This wretched computer...

My daughter managed to get a grain of rice under a key, spent months chasing it round until we got it out!

Turn keyboard upside down and tap the back, I just did mine, and found plenty of debris...
must remember not to smoke when typing, stop eating biscuits....Or try a paint brush around the keys,
if you want a real shock open up your Machine and check out the dust on your fan......lol....
remember to wash your hands afterwards......

I have a "Magic Duster" - a small brush with floppy nylon bristles that picks up dust like - well, magic. A couple of flicks over the keyboard and it's done. Great for cleaning flat screen monitors too.
