Hello.
I have an interesting case, at least for me, to see if someone has insights. My flatmate spilled his drink in his inspiron 2515. He unplugged it, removed the battery and let it dry for several days in a bag with rice. I opened it and cleaned what I could with acetone, even some spills on the motherboard. The computer starts perfectly and everything works fine, except that it has no sound (the driver produces an error) and the / key is stuck, even with the keyboard ribbon unplugged. Interestingly, with the keyboard plugged it is the g key that is stuck. The sound could be fixable with a sound card, but the stuck key makes it useless.
I have tried everything I have found on the web: upgrading BIOS, disconnecting the keyboard controllers, combinations of keys, pressing all the keys of an external keyboard, everything. Since you start the computer, you hear the bipbipbip of a pressed key. For the sound I updated the drivers of the sound card and the same: the icon appears as if no volume and a message says something like "no sound device found".
Any other ideas? Could it be the motherboard? Could that be fixed or does it need replacement? Should I take it out and try to clean it? Should I risk trying to replace it?
Thank you in advance.
