Comment 33 for bug 974455

I had the same problem...

First time i solved it by flashing to last BIOS version. But the problem returned after some time so flashing is just temporary fix. Last BIOS (56CN43WW) does not fix the problem. The act of flashing probably resets something somewhere and makes it work, until UBUNTU mess it up again. How it does I dont know, just wondering how OS can break something on BIOS level...

Next time I made couple of actions and i'm not sure what exactly made my 't' work again:

- I was Enabling/Disabling Function keys in BIOS (...that can be related to some kind of keyboard remaping)
- I Used recovery button on left side when NB was switched off and than choosed "One key recovery" (and as I don't have recovery image on my disk it failed)
- I tried to load BIOS defaults
- I accidently let my NB switched on and drained battery

Personaly I think "One key recovery" or playing with "Enabling/Disabling F keys" was the trick but I cant confirm that so for sure i'm listing all actions I took. The only true is that my 't' is back without BIOS flashing.

Hope this was helpfull...
