Hello! I have a HP 630 Notebook PC. After some time the warranty expired, I tried to clean it up on the inside, because there was too much dust and it was overheating very fast. After doing this (I disconnected some cables and reconnected them the exact same way they were), some keys are not working. I tried Hard Reset, I tried uninstalling the keyboard from Device Manager, still not working. Also, I ran HP PC UEFI Hardware Diagnostics, and it returned me this error code: UAGDWJ-0008HX-MFKR5F-G03403. Do you know any solutions for my problem? Thanks in advance!
