Recently, my laptop started displaying the message 'GRUB loading...' while emitting a really loud beeping sound (using the mute and volume adjustion keys had no effect), which always persists for a good minute. Then, when I finally get to the boot menu, I can not move the selection, it does not respond to 'enter' which should initiate the selected loader, and none of the other options work either.
Although I am not sure whether it is the cause, it started the day after I spilled a small amount of tea near the lower area of my laptop, although before I shut my computer down (after which I was unable to start it up anymore), only the '6' and left shift keys stopped working.
I have no idea on what to do, as I am relatively new to *nix systems, and I could not find anything useful on Google. I have tried rebooting multiple times, as well as not using my computer for 12 hour to let whatever tea was left in there dry out. Could someone point me in the right direction?
