Okay Guys,

My friend has asked my advice about his Toshiba Satellite Laptop.
When he presses the 'A' key, the S comes out, and when he presses the 'S', the D key comes out, and when he presses the D key, either an A, or an S comes out.

Is this a hardware fault or possibly software?
My first instinct was it could simply be dust or a buildup of dirt underneath and removing the keyboard and using some compressed gas could be the answer. (Laptops aren't my strongpoint!)

Any help would be very appreciated.

Cheers
Joe
