Aspire 3 A315-56 the touchpad does not work If I start in UEFI, I can't see any touchpad

Lightray

Hi there!
On my Aspire 3 A315-56, the touchpad does not work anymore. You can switch it on and off but without effect. The driver is installed. I already de- and reinstalled the driver (from Acer's website). Device manager sais, the device is working properly (which is obviously not true). If I start in UEFI, I can't see any touchpad... What else can I do?

Hi,
Go to BIOS and move to Main tab, press Ctrl+S buttons together, you will see the options for Touchpad, check whether it's in I2C mode or PS2 mode, if it's in PS2 mode switch to I2C mode, press F10 button to Save and Exit.

Hi BrummyFan2!
Thanks for the advice! When pressing Ctrl+S a touchpad suddenly appears, but it is already in I2C-Mode... I tried restarting in Ps2 und again in I2C mode, but still, there touchpad does not work. Any other ideas?

Best!

Hi Lightray,

Try Press and hold Fn+F7 check if the touchpad is working. If not tap on F7. 

Check this T/S and post the result.

Hi,

Did you try pressing Ctrl+S button together while in Main tab?
