Hi folks.
I've got a laptop with a keyboard that is behaving very strangely. I have checked the internal connection and it seems all good. The keys do totally random things including the odd one working correctly and others dealing out whole strings of characters. What can i do to confirm it has failed and is not just some software issue before i buy a replacement part. The machine is running a fresh 8.1 install and is an ASUS X551M.....noting flash, celeron processor.
Any suggestions appreciated.
