Argh! Have I killed dh's laptop? Problems with keyboard

[Tigaaaarghna]

Bollards!
Full stop doesn't work anymore,
And then suddenly it'll type LOADS of full stops

Happened last night
Logged off fine then logged on again this evening and probelm still there

any clues?
PLease?

Not really any good with techy stuff but is it possible that something is stuck under the full stop button? - you could try hoovering the keyboard to see if it's got some fluff in it? Good luck

Nope, keys are really tight against each other - fluff wouldn't stand a chance!

The key still depresses, it just doesn't result in a full stop on screen

yeah,. but
how c.ome. when i type the letter c.................................................................................................

that happens?.
ev.ery tim.e (oh,. and now I'.m. getting random. full stops m.id-word - hooooray! [hmm>}}]

oh
