I've seen that happen with a acompletely empty battery pack. What happens if you remove the battery pack from your laptop and try to start it up using the power adapter?

I've also seen similar things happen with faulty memory chips. Those are fairly easy to replace. My guess is that your laptop has two memory modules (since it was top of the line when you bought it), try and find out what happens if you remove one of those (test both modules).

The pen is mightier than the sword. But if you literally want to have some impact, use a typewriter
