Hi all, I'm new here and have a problem with my laptop...it wont turn on! When you plug the power lead into the laptop, the battery light is lit but when you try to turn the laptop on it goes off- there's also a small clicking sound each time I try to turn it on. I've tried running the laptop without the battery and still no success. Also if you leave the power lead in the battery light goes off within a minute...I'm absolutly stuck with what to try next- I've used compressed air etc to try and clean everything out...still nudda. Any help much appreciated!
