My 3 E D C keys stopped working on my laptop. What could I do to try and fix this?

Edit: I have taken the keys off and cleaned under them and used a can of air on them. I am using Vista. The laptop is toshiba satellite a135-s4427

please provide some more info: make and model of your laptop? operating system? and are you sure it's not just a case of Fn Lock or Num Lock? – Molly7244 Dec 8 '09 at 4:14
This also just started happening with my Dell Inspiron 1720. But it seems intermittent... sometimes they work sometimes they don't. Weird. – Charlino Mar 26 '10 at 1:57

Sounds hardwareish- being in a line like that. Clean the keyboard with a can of compressed air, see if there's anything stick under those keys. Be careful, you might shift whatever it is to somewhere worse or tricky to get to. If you want to, you might be able to remove the keyboard for better access. If it's a fairly popular laptop, a google of "laptop name remove keyboard" should find a tutorial or video.

By the way, how did you write the "E D C" in the question?!

First I'd try cleaning it in case dirt got underneath the keyboard. If you have a compressed air can, spray it underneath the keys while holding the laptop so the keyboard faces downward. If you don't have a compressed air can, blow on it!

You can use SharpKeys to ensure they are correctly mapped.
