The touchpad has been unresponsive for some time now but I cannot pinpoint when the problem first appeared.

Pressing F5 does nothing for the touchpad. On the contrary, F5 deactivates the keyboard for some unfathomable reason.

The touchpad does not even appear on the Device Manager. I've uninstalled and reinstalled the drivers, but this hasn't helped either.

I've tried having a look at the BIOS (v1.6) but I haven't found any relevant options.

I've also tested running a Ubuntu Live USB stick, but touchpad didn't work either.

Based on all this, it seems like a hardware problem to me, but any ideas or input would be welcome, before I pay for a repair.

Thanks in advance,
