Touch pad getting disabled randomly, I fix it, but later goes back to being disabled. AN515-54-728C.

I have an acer AN515-54-728C.
Firstly this issue didn't appear till about 2 months later when randomly the touchpad stopped working and the touch pad had seemingly disappeared as the touchpad settings tab in windows was gone and the device in device manager would be gone. My first thought was to get new drivers so I went to the page where I could download the appropriate drive for my system for the touchpad and downloaded it. That didn't fix it. Eventually the fix I came to was going to The Registry Edit tool and going to: \HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\System and changing EnableCursorSuppresion value from 1 to 0 and after restarting my system it fixed and the touchpad was working again. But after about 20 or 30 mins it stopped working again and I would have to go back change the value back to 1, Restart, change it back to 0, Restart, and then it would be fixed again. I'm wondering what going on or what could be occur that is disabling the touchpad. Any help as too what could cause this or ways to fix this would be great.

Before installing the touchpad driver you have to install the i/o drivers first to make it to work.

Please look at the key f6 and f7 key on keyboard . You can see the hand symbol with fingers . That denotes the touchpad function key. On some models it will be on f6 and some models it will be on f7. So we need to use the right key depending upon the laptop model . If fn + f7 is not working then we have to use f7 alone to make it to work.

On some old laptop models there will be a separate button right next to touch pad area which is beow the space bar. It is used to turn on and off the touch pad. On some old models it will be right next to power button. On all new models, f7 key is used to enable and disable the touch pad.

If you would like to disable and enable the touchpad, please press and hold fn key on the keyboard and then press f6 or f7 once. If the touchpad is not getting disabled you can either press f6 alone or f7 alone without holding the fn key. It is used to enable or disable the touchpad..

After disabling and enabling the touchpad check how it is working..

If it is still not working
Go to support.acer.com
chose your country
type snid or chose your model
go to drivers - Install the i/o drivers first and then install the touch pad driver

@William_mk2 I have already done both of these things and they have not done anything.

Some times a simple system restore will fix the issue. We can create a new user - set it as admin and check. We can always do a refresh or reset on your computer to fix the issue.

Try windows + x
chose powershell admin or command prompt admin
Type rstrui
chose an earlier date on which it was working fine.
click on finish and yes.
It will restore your computer to an earlier date on which it was working fine.

Kindly follow the details from link
