Laptop keyboard - pressing one key triggers different/multiple keys
The keyboard on my laptop has recently started to go a bit crazy. Some buttons are unresponsive, and when I press one others are often triggered, e.g. if I press a 'g' then 'gb' is entered, or ''' goes to ''/'. The most fun is that pressing space sometimes acts to refresh a page, so entire emails etc are lost (I'm typing this on a different pc).
The laptop is 3 years old, so I assume that the keyboard is just failing and I'll have to get a usb keyboard, but I thought I'd check. Could it be something to do with the key mapping?
Thanks
