ASUS K42F weird problem.

[rickybucalan]

hello tech.mates!!!

i just wanna ask for help about this weird problem of mine..

i got a asus k42f laptop w/ i3 cpu with no display at first. then i flash bios and its works and i notice keyboard is not working fine then.

i was replaced the keyboard cos some keys are not working. then now it works.

after a week it comes back to me and client says that the keyboard was not working and its typing character by it self. so i replaced it with another one.

but the problem is still the same. its typing by it self even i disconnect the ribbon of keyboard to the mainboard.

i used usb keyboard but it still the same.

i also think it might be bios issue. but it was not cos i already tried to flash the bios 2nd time.

any idea would releave my stress.

tnx in advance.

If it is your first SIO replacement, I recommend you practice it on an scrap board first. then, do it on this board.
