Intermittent keyboard and trackpad issues

[DavidNE]

For a month or so, I'm starting to have intermittent issues with the keyboard and trackpad of the laptop.

The keyboard stops working until the laptop is restarted, or the trackpad does the same. The issue is increasing in frequency, to the point I cannot use the laptop more than a couple of hours at a time most of the times.

I have also gotten several times a CMOS error when doing the restarts which I'm not sure if it's related or not.

The trackpad error often persists after reboots. The keyboard hasn't at least yet.

I tried following:

The only step that seemed to have an effect was the bios reset.

It seemed to fix the trackpad (but I cannot be sure as it's a bit random it's getting fixed) and the keyboard seemed to last a bit longer than usual (about a day) but it failed again.

I tried to load a linux distribution via a live usb while the trackpad wasn't working and it wasn't working either, which makes me think of a hardware or bios issue. On linux (Ubuntu) the trackpad typically works fine.

Any ideas what could I do? I still have the warranty under Spain (2 years) but if it's solvable it would be better to not be without a laptop for a while.

Thanks!
