hey, i have an interesting problem. theres this hp laptop that im working on, a pavilion dv 4000 , the user was having wierd problems with it. wen you turn it on, u hear repetitive beeping, like wen keys are being held down... it boots.. after the boot screen, then you start seeing the caps lock light turning itself on and off. it doesnt respond sometimes when u click icons...alot of crap. the mother board was replaced and it was still giving the same problem. i disconneted the keyboard...same problem...plugged in a usb key board, still the same thing. managed to get notepad open and characters n,b,&, c, = and a few others keep repeating themselves. i have reason to beleive that the alt and ctrl keys are stuck too...cus certain shortcut combinations are also activating themselves. the tap to click ofr the touchpad sometimes stops working after a while too. i also tried booting an OS that runs in ram..puppy linux....at the boot screen those characters typed themselves in too.
im wondering if its possible that the BIOS was messed around with...because thats the only logical answer i can come up with...besides it needing an exorcism....
