| 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.

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.
