when ever i take the battery out of my acer aspire 5920 the 1 2 q w a s z x fn both of the ctrl and shift keys tab capslock ` and esc keys stop working. the first time this happened i fix it by a hard reset, the second time the hard reset didn't work, so i had to take out the cmos battery cable for a few minutes. this time none of these things worked and i'm out of ideas. i have updated the bios and a lot of other things like that, i just need some help. will i be able to fix this problem or do i have to take it somewhere to be fixed and what is causing the problem. help would really be appreciated because the on screen keyboard sucks.
