Comment 7 for bug 65249

A couple of observations:

1) On my Sony Vaios at least, they plan for the keyboard to be removed for access and cleaning. 3-5 screws on the base are removed with a Jeweller's screwdriver and then the keyboard lifts up at the back. The clip holding the flat plastic cable into the connector on the circuit-board can be flipped up with a thumb-nail and the keyboard removes.

2) I had a recent weird experience that was keyboard-related in an oblique way. I usually alter the BIOS typematic rate settings so the repeat-rate is as high as possible. This usually means it goes from 4/second to 30/second. On one system it took me over 6 months to discover it was the reason that the Grub countdown timer ran about 8 times too fast - I'd had to increase the timeout to 200 to have 5 real seconds to press Escape!

So, with that in mind is there anything in the BIOS settings that isn't default, or could conceivably relate to keyboard, including interrupt settings?
