Chosen Solution
Alright so my grandparents had somebody over, idiot spilled water on the laptop. Luckily for some odd reason, the laptop survived no problem. Anyhow, since the incident, the specific Keys don’t work.. B N += Caps and Del I’ve read online that this particular combination seems to be going out on many other HP laptops. Here’s a few forums I’ve found. http://h30434.www3.hp.com/t5/Notebook-Ha… http://h30434.www3.hp.com/t5/Notebook-Ha… http://www.askmefast.com/Caps_lock_B_and… http://www.tomsguide.com/answers/id-2706… Anyhow, I’ve completely disassembled the unit, cleaned it out, made sure there’s no water. Took off the keyboard, placed it in a rice bag for a week, hair dryed it. Etc I plugged it in, keys still don’t work. Funny thing is I have an old husk that’s the same model (which I used to build the laptop in the first place, using the best bits) I used the old banged up keyboard and the keys seem to work in reverse.. The B N += Caps and Del all work, but nearly everything else doesn’t. So I guess I can rule that the keyboard itself is somehow wrecked in a weird, ritualistic kind of way. Anyway I can dispel this wretched magic upon thine key tiles? Thanks
The keyboard is driven by a matrix of wiring underneath, shorting out or disconnecting some of them will cause some particular keys to malfunction. You can try with a known good keyboard. If that keyboard is working, then your keyboard is broken. If the same issue persists, then there is something wrong on the main logic board.
