Aspire A515-43 touchpad not showing in device manager ;(

Kabud

After I was using an external USB mouse for some time and disconnected it- my TOUCHPAD stooped responding. Restart did not help. 
TOUCHPAD does not show in device manager either.  Can i resolve it  on a DRIVER or other software level?
Thanks a lot for answers

Sometimes a simple system restore will fix the issue.. 

Try windows x

click on power shell admin or command prompt admin 

type rstrui

chose an earlier date on which your computer was working fine  

click on next, finish, yes

It will restore your computer to an earlier date 

if you get an message - system restore not completed - click on close 

It will show you all the icons..

Try and check whether it is working now ..

If it is still not working.. 

Try windows + r - on run type msconfig 
Go to services tab - check  the box - hide all microsoft services
click on disable all and enable all 
click on general tab - chose normal startup
apply - ok 
Restart the computer and check.. 

If it is still not working.. 

Try fn + f6 or f6 alone  or  fn + f7 or f7 alone on keyboard to disable and enable the touchpad. 

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 below 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

I am really sorry for the inconvenience..   Let us do the basic steps first..

Doing the power drain and bios defaults will really help.  Kindly follow the steps given below:

Turn off the laptop. Disconnect or unplug the charger cable, devices or any other cables connected to your laptop. Close your laptop. Turn it upside down.  On the bottom of the laptop, you can find a  pin hole. It is a tiny hole. You can a find a battery symbol indicator next to the hole. It is like a + and – sign symbol as though somebody is trying to shift the battery out. Insert the pin on to the hole for 30 seconds. Remove the pin. Flip the laptop. Connect the charger cable, turn on the computer.  Only on laptops where the battery is inbuilt you can find the battery reset hole on the back of laptop.

If you don’t find a pin hole on the back of laptop then you might be using removable battery. There is no need to unscrew anything to remove the battery.  Turn off the laptop. Disconnect or unplug the charger cable, devices and any other cables connected to your laptop. Close your laptop. Turn it upside down.  On the bottom of the laptop, please look at the top or bottom depending on the way you look at it. You can find a long door. It is a battery removable door.  Just below that you can find a latch.  If you move the latch you can remove the battery door. Once the battery is removed, flip the laptop. Open the top cover, press and hold the power button for 1 minute. Connect the battery back on the back of computer. Connect the charger cable back and then turn on the computer. 

 

If you don’t see a reset pin hole on the back of laptop or if you are not able to remove the battery (if it is inbuilt) then please unplug all the cables and devices out of laptop.   Hold the power button for 1 minute.  After releasing the button you should wait a while before plugging in power. Just because the button has been pressed doesn’t bleed off all the residual electricity on the motherboard. Wait 15-30 minutes before plugging in power. Then once power is connected wait for a full battery indication before turning the system on. That allows the battery to fully reset it’s internal statistics.

Connect all the cables back and restart the computer.  

While turning on the computer, tap f2. It will go to bios. Press f9 once. It will show load bios defaults with a yes or no popup. Press enter. Popup screen will disappear.  Press f10 once. It will show save changes popup with yes or no. Press enter. Computer will restart and it will load into windows.   

 

 

It should work fine..
