Windows is not shutting down completely or Restarting by itself when connected to power adapter or Docking station |Windows 10|

Welcome to my other post where I am going to tell you about another interesting fix where we are going to fix one more Windows 10 issue in which Laptops just restarts by itself when you choose to Shutdown the computer and it auto restarts by itself especially when Laptop is connected to Power sources like Docking Station or AC Adapter.

No matter how many times you try to shut the computer down using the power button, using Start menu shutdown options, shutdown command or creating a shortcut but it will always restart.

But seems like power source is somehow triggering it to restart, initially, I had a thought that it could be an issue with the HW of the computer because it was shutting down all the ways and then restarting from outside of the OS. But later identified issue started to occur after 1803 update on the Windows 10 PC and when tried rolling it back to a 1709 update of Windows 10 this issue disappear hence to regenerate and confirm that issue is with Windows alone reinstalled the Windows 10 1803 upgrade now the issue came back.

Did research and found this issue mainly on i7 processor working on Windows 10 1803 version and found a fix as well.


FIX

Open Run Box (Win logo Key + R) Then type powercfg.cpl to access the power options page as in below image:
Open Run Box (Win log Key + R) Then type powercfg.cpl to access the power options page as in below image:



Then click on "Choose what the power buttons do", as highlighted in yellow in the above image.

Then uncheck the box "Turn on fast startup(recommended)", as highlighted in green in below image:



If you are successfully able to save this option then try shutting down the computer and see how does it work. If you are successfully able to Shutdown the computer then your issue is resolved or else you can try below command to remove this setting completely:

POWERCFG -H Off


Run this command with Admin rights to make it work.

Issue Status: resolved.



Problem Detail:

This one's relatively rare, but it's a big enough problem that it's shown up on several different support forums: When you install the Creators Update it might automatically enable Windows' Fast Startup option, which puts your PC into a low-level hibernation state when you shut it down.
Fast Startup can create more problems when booting up, like getting stuck at the BIOS and having to pull the power plug to get the PC up and running again. It can also make it difficult to access the BIOS if you need to change boot settings or check on an overclock mode(S3,S4,S...n, hyperthreading and turbo boost)in BIOS. Luckily, there's an easy fix. You just need to disable hibernation with our good old friend, the command prompt "CMD".
If you are still facing Windows 10 Auto restart issue, and it does not matter whether the AC adapter/Docking station is connected or not, then Click here for a fix.

Android P the Pie is Android 9 |Android|

Android  P the 9th Edition of the Android Operating System is Android Pie.
The first look was issued and this new OS by Google is ready to rock the mobility market.
Android and the Pie were spotted in Google's California Based Headquarter on 7th of August 2018.

The much awaited Android Pie is focused on simplicity, intelligence, and well-being. The on-air updated has been released for Eligible Google Pixel Phones and Essential PH 1.

A lot of amazing features are said to be included in this version of Android 9, but what caught my interest are:

The new Slice Feature of the Android Pie is said to be very powerful as it enables the partial function of the app to be active without even opening an App, for example, like you can book your UBER cab without even opening an App.

Another feature Digital Wellbeing is something which will track your habit how you use your phone, how many time you unlock the phone which app you use the most, how many notifications you received from where and also let you take the control like how you want to do things. Digital Wellbeing represents the Dashboard where you can see all these traced activities. Another feature is you can set the timer for the App you want to use, You can utilize Do not disturb mode now and also add a time to remind you it's time to go to bed and make you practise healthy routine.

Now we will talk about simplicity that means this version of Android is very easy to use, you may find it is even easier to navigate through the apps and running apps on this version of android then ever.
So we know this Android version is Android Pie which is also known as Android 9 or Android P and their earlier names of Android Operating system are as below:
  1. Android Donut (v1.6), The beginning of a new era of mobile computing.
  2. Android Eclair (v2.0)
  3. Android Froyo (v2.2)
  4. Android Gingerbread (v2.3), A big milestone, excellent graphics and high-end gaming. Remember Dell Streak.
  5. Android Honeycomb (v3.0)
  6. Android Ice Cream Sandwich (v4.0)
  7. Android Jelly Bean (v4.1). Another milestone with changed GUI.
  8. Android KitKat (v4.4)
  9. Android Lollipop (v5.0)
  10. Android Marshmallow (v6.0)
  11. Android Nougat (v7.0)
  12. Android Oreo (v8.0)
  13. Android Pie (v9.0), The present.
As you can see all the above naming given to Android Operating Systems are based upon the name of Sweets, so the latest one is based on the name of sweet American Pecan Pie. 

How to enable Wifi and Lan at the same time ? | Windows 10 |

One of the recent questions raised to me as if we can use Wifi and Lan at the same time, the generalized answer is no we can not use it at the same time, second question - is there a workaround to this situation?
This is something I need to check out for!
So in order to search about did some research and found that many people posted a fix for Windows 7 but could not find the accurate fix for Windows 10 or we can say no one has really tried it so far.
So let's go ahead and make a note of what people were doing on Windows 7 and then we will try to replicate them in Windows 10.
Tried below steps:
Chances are, your laptop's wireless card has a "disable on wired connect" feature configured as a default.
  • In the Windows 7 Control Panel, launch Network and Sharing Center
  • Click "Change Adapter Settings"
  • Right-click the wireless adapter you're using
  • Left-click "Properties"
  • On the Networking tab of the Wireless Network Connection Properties window, click "Configure"
  • That will display the properties window of the wireless card.
  • Click the "Advanced" tab and see if there's an option for "Disable on wired connected" or Something similar to it would be there.
  • If there is, and it’s enabled, disable it.
Check in BIOS settings:
Some computers have a BIOS setting that determines this behavior. Whether this BIOS feature exists and where to find it is model-specific, but here are a couple of examples, which should at least help you figure out what to look for if you have a different model.
  • On HP laptops (probably all recent models, but I can vouch for EliteBook, ProBook, and ZBook systems), switch to the System Configuration tab, select Built-In Device Options, and uncheck the box next toLAN/WLAN Switching
  • On some laptops, go to Settings→ Power Management → Wireless Radio Control, and in the right pane uncheck the box next to Control WLAN radio.
Then one of the fellow friends suggested to try bridging:
  1. On the Windows 10, click on the Windows icon. Type view network connections and press Enter. (You can also type NCPA.CPL in Run Command box, Run Command box can be opened using WinKey+R).
  2. Identify your Ethernet connection and your wireless connection. The Ethernet connection is called Local Area Connection and the wireless connection is called Wireless Network Connection.
  3. Click on Local Area Connection to select it.
  4. Press and hold the Ctrl key and click on Wireless Network Connection to select it. Now you should have both connections selected.
  5. Right click on the selection and select Bridge Connections.
This legacy setting was superseded in Windows 10 with a new setting that is the "metric" much like in typical networking.
Go to your adapter properties, IPv4 settings, (keep current DHCP or static IP) and click on the "advanced button". There you will see the new checkbox andautomatic metric the textbox to enter manually at your discretion. The lower the number the higher the priority.
So as concluded for Windows 10 Machine try bridging the networks and see if works for you as well.

Now restart the computer it should be working. 

Note: If still not working it may be some issue with HW, to ensure and verify that issue is not with the HW you can try to boot the computer using the Bootable DVD Media. If it boots up through DVD then above steps should work or the DVD drive may need the special Drivers to run the type of DVD users may trying to run, for this, you can always look out for it on manufacturer's websites and applications provided with the computer. 'cause sometimes it happens that user tries to use the Blu-ray media and without proper application or nonsupported drive hence also need to check the kind of Media being used by the users.  

Webcam not getting detected - Laptops |Windows10|

Internal Webcam Not working inside Windows 10: 

Windows 10 users may come across the issue when they will notice that the Webcam is not at all working and not getting detected in device manager in laptops & all in one computer.

May get worried that Webcam itself has gone faulty, but it is too soon to worry, so we have simple and easy issue identification technique and we can resolve the issue as well.

But before we proceed we need to verify whether it is a Software issue or Hardware (About which you are worried) issue.

Issue Identification:

First, we will go to the device manager and check for if the Webcam is getting detected under Other Devices, Imaging Devices or Webcam, it should get detected in either one of them.

If getting detected, then it is a simple issue with drivers open properties to check for status and try to uninstall and reinstall the driver form appropriate source.

Just in case it is not at all getting detected in device manager then there is no way to work around with the drivers, hence in this condition, we need to check the Webcam is set to on in system BIOS or not.

To check it I will recommend checking it in BIOS, depending upon your system’s manufacturer go into BIOS, nowadays most of the BIOS manufacturer supports have the option to turn Webcam on and off in BIOS.

If the option is not present in BIOS then it should be by default on or you do not have the webcam, check your invoice details and confirm your laptop has this feature, and just in case if it was working fine better then you do not need to check it in the invoice. Now we are sure that webcam is all set in BIOS so now we will try the below fix.  

Fix

Go to device manager and click on view menu on top select View Hidden Devices, now see if you see anything under Imaging Devices or Webcam, just in case you find something new in there which is transparent just right click them and click on Uninstall, then go to Device manufacturer or chipset Manufacturer website and install the chipset drivers & USB drivers, Because Webcam works through internal USB port.  now restart the computer. You will find it is working just fine now.

In most of the cases, you will find this specific issue when the customer will report after doing operating system installation their Webcam is not working. Chipset driver and USB drivers are a fix for this issues.



| Windows 10 | Touch Pad not working.

Touchpad Not working inside Windows 10: 

Windows 10 users may come across the issue when they will notice that the touchpad is not at all working and they tried connecting external USB mouse and it was working just fine.
May get worried that touchpad itself has gone faulty, but it is too soon to worry, so first, we have to try simple and easy issue identification technique and we may resolve the issue as well.
But before we proceed we need to verify whether it is a Software issue or Hardware (About which you are worried) issue.

Issue Identification:

First, we will go to the device manager and check for if the TouchPad is getting detected under Human Interface Device and Mouse and Keyboard input devices, it should get detected in either one of them.
If getting detected, then it is a simple issue with drivers open properties to check for status and try to uninstall and reinstall the driver form appropriate source.
Just in case it is not at all getting detected in device manager then there is no way to work around with the drivers, hence in this condition, we need to check the Touchpad functionality outside the operating system.
To check it I will recommend checking it in BIOS, depending upon your system’s manufacturer go into BIOS, nowadays most of the BIOS manufacturer supports Mouse and Touchpad support try checking it there.
Just in case if your BIOS does not support Mouse and touchpad in BIOS then try to check it in Windows Recovery.
It will conclude to two situations; 1: Touchpad is not working in BIOS/Windows Recovery. or 2: Touchpad is working in BIOS/Windows Recovery.

Fix

Situation one: Touchpad not working in BIOS and Windows Recovery, then it is identified as Hardware Problem you should contact the manufacturer for getting it repaired or contact local IT to get it fixed for you.
Situation two: Touchpad is working in BIOS/Windows Recovery, go to device manager and click on view menu on top select View Hidden Devices, now see if you see anything under Mouse and Keyboard input devices or Human Interface devices, just in case you find something new in there which is transparent just right click them and click on Uninstall, then go to Device manufacturer or chipset Manufacturer website and install the chipset drivers, now restart the computer. You will find your touchpad is working just fine now.
In most of the cases, you will find this specific issue when the customer will report after doing an operating system installation their touchpad is not working. Chipset driver is a fix for this issues.

Issue identified when system is only on battery so we can try below before concluding any Hardware issue :

Open Device manager by right clicking on Windows 10's  - Windows logo on left hand bottom which is for opening the Start Menu as below:
Now go to Network Adapter and check by any chance if you have Intel Dual Band Wireless card in there, if yes double click on that to open its properties then click on Advanced

 Now in Advance on left hand side look for properties and in properties look for Transmit Power then on the right hand side change Highest to Medium Then click OK.
Intel Wifi may or may not be part of your computer hence if this option is not there then do not worry you can proceed with next step. 

As we know that the Speaker is being Static only when the AC adapter is connected hence in this case we will try to uninstall and reinstall the battery driversin device manager.
To uninstall the Batteries Drivers check the above image expand the Batteries and right click Microsoft AC Adapter then select uninstall, do the same for Microsoft ACPI-Complaint Control Method Battery, once this both option are invisible from the device manager then click on the icon which is highlighted in green above with a arrow mark, which is for Scan for Hardware Changes, Click on it and it will reinstall the Drivers.

Now check the Speakers they should be working fine now.

How to Enable SCCM /Network installation on UEFI client BIOS and enable Network Boot

Issue: Need to boot from Network in UEFI mode, changed BIOS settings and system is still not loading up the OS.


Problem Description: You got the latest machine Intel processor Generation 8 or 7 I processor, and the supported chipset has Latest BIOS is set to UEFI mode and a this BIOS setting does not even support Internal Storage devices anymore in old known LEGACY MODE.
While doing Operating System Reinstallation on Legacy Mode users are able to see the windows files are loading to Hard Drive and it is successfully finishing the installation but then again booting the computer to NO BOOT Device found. That means the Hard Drive has the Legacy image but a computer will not let it boot from there.  If you want to verify this fact you can set the computer on UEFI MOde and try to add the boot device while adding it you will find MBR files are present in HDD which is for Legacy, and EFI files missing which are needed for UEFI Boot. 
People trying to boot through the Legacy LAN options they are finding it difficult to boot it properly because of the problem described above from the SCCM servers.  Because of the image loaded on the SCCM server is the LEGACY image(This are customer image so they can not decide the format they just print themselves on the Hard Drive, and these images are in LEGACY Format). Here IT technicians have to inform there Deployment Administrative team about the situation and recommend them to create another customer UEFI image which will resolve all these issues. 

Once the UEFI image is deployed you need to boot the computer in UEFI network mode which we have described in the below article. 

Follow below steps to get the issue fix: 

To fix this issue you need to go into System BIOS, you may do it by pressing DEL, ESC, F2 or any other key as per the System Manufacturer's guidelines.

Once in BIOS make sure UEFI and Secure boot both are on, now look out for System Configuration or Advanced options in BIOS and in there you may find something which says Network click on it and then put a check mark on UEFI Network Stack. 

To be on safer side we can also disable TPM from Security, just disable it so that it will not cause any issues loading up from Network.

Now go to one-time boot menu by pressing F12 on the manufacturer logo and it will take you to the list of the device through which you can load from different sources. So here you will find that the traditional option with legacy option ROM was Boot From Network but now after making the changes you will find the new option under UEFI boot device are IPV4 and IPV6 so here you have to select IPV4 and here you go it will load up the windows.

If it still fails to load windows or any other OS then you need to check with SCCM task scheduler whether it is configured for UEFI supported OS or not.

Once configured properly you will not find any issues.

____________________________________________

Above steps are very genuine and effective way to take care of the issue but just in case you still want to go with the LEGACY MODE due to some reason then you can try to downgrade the TPM Firmware rom 2.0 to 1.2. Some of my users have reported that is enabling the  Internal Hard drive boot on the computer.

Audience: IT Technicians with higher computer technical experties, kindly do not try above steps if you do not undertand the content. 

How to run IE 9, 8 & 7 compatible web pages in |Windows 10|

You may find that many a times you come across some websites which does not support version above IE 9, they  give errors that this website just support IE 6,7 and 9. But as known fact we all knows that Windows can not support any version below IE 11 and its keep on updating.

So what to do if you have Windows 10 installed on your computer and you want to use the Website which supports lower version of Internet Explorer.

So there is a work around though some of the users may find it little time consuming and hectic but still it is the only way you can run degraded Websites on the Windows 10 platform without any problem.

To fix this issue you need to open Internet Explorer make sure its not the Edge browser, you specifically needs an Internet Explorer to do it.

To open Internet explorer you can type Windows Key + Q to open Cortana Search and type in Internet Explorer or IE in there and it will show you the Internet Explorer on top of it as in below image.

If you are going to make use of Internet Explorer again and again the I will recommend you to right click the Internet Explorer option select the option Pin to Start as highlighted in above image.

Now open Internet explorer and then click on the gear icon on the right hand side top of the page and the select Developer Option you can also open Developer Option  by simply pressing F12 key on the Keyboard. 

Once the Developer option is open you will get horizontal bar at the bottom of Internet Explorer, there you will find option which says Emulation click on it and there would be option underneath it to change User agent String there select Internet Explorer 9 as in below image:
Now on the right hand side of Emulation you will find a small Desktop icon with Mobile icon in it click on it and select as in below image: 
That's it now open the websites you want to run in IE 9 compatibility mode in IE11 and you will find it to be working just like your old Internet Explorer 9. 


Best way to get into Device manager | Microsoft Windows |

As you already may know your best way to get into Device Manager, may be you might be using Windows 10 and now that right clicking on Windows Start Logo will give you option to open device manager, or you love to just simply type Device Manager in Cortana or traditional Windows Search box and open device manager or any other way.

But maybe sometime the Search Box may not work some time it may not be Windows 10 and you may just have Windows 7 where you have to right click on My Computer then click on Manage, then on left hand click on Device manager.

But the best to open Device manager in any situation is Windows Key on keyboard + R key on the keyboard.

Which will pop up the Run box and you can type in there Devmgmt.msc and it will open up the device manager, just like in below image:

Just in case Windows + R key due to some condition with the windows operating system and you are not able to find a ways to open device manager, then you can open a Run box through Task Manager, to do that you need to press CTRL+ALT+Delete keys on the keyboard and it will go to blue screen from there select the option Task Manager it will pop up a Task Manager box and if you are using Task Manager for very first time you may find some thing like  below:

So need to click on More details and it will bring up the full page of task manager as in below image: 
Now  again you will get a new task it will bring up Create new task box.
You have additional benefit of this box over run box, that is you have a privilege to run the new task as an administrator in here.
So when you want to run CMD, Device Manager or any troubleshooting apps using Administrative privilege and your Start Menu is not working or you have logged into an user account then try using Task manager. 

About This Post: This is just a general idea and base foundation to many other troubleshooting we will be sharing in our past and future posts, so may be possible if you just reading this post you may not be able to make out anything out of this post and may think that why this post is here but it is addition to many other upcoming post.

Touchpad cursor erratic movement when the power cord is connected | Windows 10 |

You may come across the trouble that sometimes you find that the touch pad is working very erratic or lagging while you may have connected the AC adapter to the computer.

You may find that why it is changing its behavior while the adapter is connected.

You may also conclude that there must be some problem to the computer physically and the power supply is affecting the behavior of the computer.

But the reason behind the erratic behavior of the cursor lies with in the software and with the windows nothing to do with the physical hardware of the computer.
To ensure it I will recommend that you should go into the system BIOS by pressing DEL or F2 or ESC key at the boot depend upon the manufacturer of your chipset, if it is recently purchased computer recent means like within 3-4 years from now then I believe it should support mouse in BIOS and try to check it there with and with the AC/Power cable plugged in and see if it still shows erratic behavior in there, if not then it is confirmed that it is nothing to do with the HardWare.

So it leaves us with two situations:

1: If it does cause trouble in BIOS(for people who does not have cursor support in BIOS they can try using WINDOWS Recovery mode, I think I have discussed that in my previous post that how to get in there)  then you already knew it has something to do with HW so you can check it out with Hardware support for your computer they will replace either the Touchpad or the DC in or maybe both of them.

2: If it does not shows any erratic movement of cursor in BIOS or winRE mode then you are left out with software troubleshooting which I am going to help with as below :

Click on Windows Icon and type in on Cortana EDIT POWER PLAN


Select Edit power plan option as in above image it will bring up the Edit Plan Settings box as below:

Now click on Change Advanced Power Settings and it will bring up other box where you will be having different power options to select first thing first ensure you assign the power button action to Shutdown in there, because my experience with Hibernation has not been good on Windows 10 machine.  Last time I used Hibernation was with my Windows ME machine back in year 2002, found it to be major cause of No Boot issue. The reason why I do not recommend Hibernation will be explained when I will tell you about fixing Sleep Issues in Windows 10.  So for now lets stick to Erratic cursor issue.

Now just like in below image ensure that the USB selective suspend settings are enabled both in battery and without battery.
Now the Critical battery action.
In above image it shows Hibernate but you need to change it to Shutdown on  battery and Do nothing when plugged in.  It will somewhere help you PC to be very actively understanding the devices and the setting in the computer.

Now we are done with the edit power plan, Just to ensure that every thing is correct and this system will now never go in Hybrid Sleep/Hibernate then run one last command.

Open command prompt with Admin rights just like in below image:

Once in command prompt type in Powercfg -h off and press Enter
We are completely done with the editing power plan has been completed.

Now our actual Troubleshooting will start form here now open Device manager by right clicking on Windows 10's Windows logo on left hand bottom which is for opening the Start Menu as below:
Once in Device Manager expand Human Interface Devices:
Underneath Human Interface Devices check for USB Input Device
Now Double click on USB Input Device Options and open their properties box and on top select Power Management:
Now remove the tick mark from "Allow the computer to turn off this device to save power" repeat this step for all the USB input devices.
Now go to Universal Serial Bus controllers:

Here double click on the below option and even change there Power Management as we did in USB input Devices, check all the option for Power Management and remove the tick form all option listed under USB Controllers:

Now go to Network Adapter and check by any chance if you have Intel Dual Band Wireless card in there, if yes double click on that to open its properties then click on Advanced

 Now in Advance on left hand side look for properties and in properties look for Transmit Power then on the right hand side change Highest to Medium Then click OK.
Intel Wifi may or may not be part of your computer hence if this option is not there then do not worry you can proceed with next step. 

As we know that the cursor is being erratic only when the AC adapter is connected hence in this case we will try to uninstall and reinstall the battery drivers in device manager.
To uninstall the Batteries Drivers check the above image expand the Batteries and right click Microsoft AC Adapter then select uninstall, do the same for Microsoft ACPI-Complaint Control Method Battery, once this both option are invisible from the device manager then click on the icon which is highlighted in green above with a arrow mark, which is for Scan for Hardware Changes, Click on it and it will reinstall the Drivers.

Now the final step click on Cortana Search Box and type in Touch Pad, it will populate the Options Select Touchpad Settings:
Now look out for the option as in below image which says Medium Delay,  just change it to No delay.
Now check and you will find that your issue is resolved and it is no more lagging or freezing while on AC adapter.
