[G3-572-7526] Standard/PS2 Keyboard Driver Missing + Elan EzTouchFilter not working

YoshiReddy

Hi for the past two months my laptop keyboard has not been working. I have done practically everything short of sending it to a physical repair shop, because I am adamant that the problem must be software-related. My laptop keyboard does not work (none of the keys except the power button; but the touchpad is still good), but it does work when I run BIOS. After doing hours of troubleshooting, I discovered a few things: I'm missing my Standard/PS2 driver, Elan EzTouchFilter is giving me a Code 10 error, and Detection Verification is giving me a Code 45. Even after clearing my laptop and restoring to factory settings, I am still stuck with these same Driver problems. I have been using my laptop with an external keyboard. 

When I go into the Elan EzTouchfilter and look up "Problem Status" I come back with this:
Insufficient system resources exist to complete the API.

C000009A

Status hits me with:

01802400

DN_HAS_PROBLEM

DN_DISABLEABLE

DN_NT_ENUMERATOR

DN_NT_DRIVER

Basically, I can only use my laptop keyboard in BIOS. I believe I have a software driver problem.
Thank you.

Tried installing the drivers from Acer Support page for touchpad? Try updating keyboard driver from Device Manager.
