For about two days now, certain keys on my keyboard have suddenly been behaving erratically, on and off. They are the 't', 'y', left ctrl and tab keys. Sometimes they do not work at all and other times they register 2-5 presses instead of 1. It has been infuriating to even type these three sentences! In fact, it is the exact problem outlined here, by another user, with the exact same keys: http://h30434.www3.hp.com/t5/Notebook-Hardware-e-g-Windows-8/Keys-not-working/td-p/2534251
I have tried the disconnecting battery and adapter + holding power button trick, as well as uninstalling and reinstalling the latest keyboard drivers. The keys do not work as expected in the command prompt either.
Any help would be appreciated!
Edit: My laptop is a HP pavilion g6 by the way, using Windows 7. T and Y seem to be common keys that are unreliable with HP laptops but I cannot find a solution online.
