Right, Here goes...
The laptop only displays the error when the battery charger is plugged in.
However after starting the computer system up she cannot connect to the internet, just says can't find any networks in range. Also it says that Wireless compatibilty is turned off and there should be a button on the laptop to toggle this on/off however there isn't.. Any way to do this from the OS?
Also there were 76 program errors displayed e.g. Internet Explorer failed etc.
But, It's still in Warranty

haha
so i'll help her back up files onto USB Sticks and tell her to send it to Dell after a phone call...
Thanks very much for you help
