Why is the MacBook Keyboard not working after upgrade to 10.9.2?
I am (not a Mac expert) trying to repair the Macbook of a friend, whose keyboard has stopped working after an upgrade to 10.9.2. It is an icelandic keyboard and right now types only three characters and all others either do not respond or come as blank spaces.
An external bluetooth keyboard and a usb keyboard work fine. Tried to reset (through the usb keyboard) PVRAM but it keeps going into the Mac utilities, safe mode option is also not working. Could not reset SMC with the Shift-Control-Option keys (on the left side) and the power button... so opened the back panel and disconnected the battery connector and pressed the power.
When I go into Mac Utilities (where I reached instead of PVRAM reset) there is a log for which I have not found any clue on the internet

Please guide me as to the next step.
