Hey all, I’ve encountered a weird problem with my friend's HP G62’s keyboard. Certain keys have stopped working – most of the keys on the A-L row, plus the backspace key and a couple of others. Mostly the problem manifests itself when attempting to log into Windows. Occasionally I can log in without incident but the problem always appears again sooner or later. Originally the problem was intermittent but slowly became more common and is now pretty much constant (though not always). Initially I thought it was a hardware fault with the keyboard (the laptop is a few years old now) but after a bit of investigation I’m not so sure. All the keys appear to work in the BIOS – I tried setting a BIOS password just as a test and all key presses are registered just fine. I didn’t actually save the changes though as I didn’t want to risk not being able to access the BIOS again, but nevertheless the keyboard seems fine in the BIOS. I have repeated this test several times and always the key presses are registered. This led me to believe the problem might be related to Windows – e.g. a driver issue or other such software conflict. I set about (with heavy use of the on-screen keyboard) rolling back, updating and re-installing the drivers respectively as well as messing about with the installed keyboard languages/layouts but nothing seemed to work. The same keys are still failing inside Windows – but not in the BIOS. I also tried returning the laptop to factory settings but that didn't work either. I decided to re-format and re-install Windows completely (a reinstallation was long overdue anyway!!). I installed Windows 7 Pro from a verified-working disc (I’ve used the same disc for several problem-free installations on other PCs) but when it came to creating a user account and password the same problem with the same keys occurred again. So, maybe not a software fault then… but all the keys work fine in the BIOS which would suggest it’s not a hardware fault either… help! I haven't been able to try a Linux live CD as I haven't got one floating around and I'm all out of discs atm. I'll get hold of some soon and update the post if it sheds any light on things. Anyone know what could be causing this and what, if anything, I can do to fix it? Is it something to do with the BIOS being so low-level that whatever hardware fault is preventing Windows from registering the key presses is not affecting the BIOS? Is that even possible? Don’t most OSes ‘talk’ to the hardware through the BIOS anyway? I just can’t understand why the keyboard seems to work flawlessly in the BIOS but not elsewhere. Perhaps it’s a bug in the BIOS itself? Faulty MoBo? Extra-dimensional entity taken up residence in the keyboard controller? I was originally going to simply replace the keyboard but I’m not sure if going to the expense and trouble of doing so will yield any results now. Btw if it helps, and to save potentially going over old ground, I’ve tried a few other things too before posting here, after a few searches and perusing HP's support forums; Tried a USB keyboard and this worked fine – so at least I know there’s no problem with the USB ports Also tried a suggestion I found on which involved removing the battery and holding the power button down for 30 seconds to remove any residual charge, then plugging in and booting up straight to the BIOS without the battery attached and resetting the BIOS to default settings. This didn’t work either - and I tried it twice just to make sure! Any feedback or further will be greatly appreciated. Cheers.
