After a motherboard replacement of my acer aspire A515-45-R4kx, from acer authorised center itself, the keyboard started misbehaving. most keys are not working and some those are working, behave abnormally. On pressing the window key, the laptop goes to lock screen and in the lock screen, it behaves as a scrolling button. same for the Y,R,Q or any other key.

The laptop is under warrenty and motherboard was done under warrenty. The technician said keyboard needs replacement, but with earlier motherboard, it was fine. the old motherboard was dead due to a IC issue. external keyboard is working fine.

Is the motherboard faulty or the keyboard and how to fix it ?

Hi,

Go to Device Manager, expand Keyboards, right click Standard PS/2 keyboard and select Properties, move to Driver tab and uninstall the driver, reboot and see whether it helps.

You could try checking the cable connection before sending it for another repair service, contact Acer support centre explain everything to them.
