fault on toshiba satellite keyboard fix

i have recently had a warranty motherboard replacement from toshiba on my satellite c870-156,
bearing in mind the laptop is only 6-7 months old from brand new.

since it was returned to me the keyboard is now faulty

basically the keyboard types the 'Q' by itself, the key is not sticky and is not stuck down, if i do not touch the keyboard or mouse for maybe a minute or 2 then once i touch either it will start typing the Q, it only does it when using internet browsers.

i sent it back to toshiba for this fault and they returned it with a note saying they could not find a fault.

what can i do myself? i took the keyboard off to make sure the connection was seated correctly and there was no debris

apart from replacing the keyboard what can i do??

You can connect a usb keyboard and see if that works if it does could be a driver problem If all else fails i would get in touch with Toshiba again

ok i fixed the problem by doing a factory reset, must have been a driver issue or something similar..

Glad to see you got it sorted
