I've been handed a laptop to "clean-up", it appears to be infested with spyware and various limewire type downloads.

It had a habit of randomly shutting down after 30 seconds, BSODs if cables connected and so forth.

I've booted into safe mode, installed CCleaner, did a quick cleanup of the registry and removed a load of temporary files. Next I installed Avast antivirus and hey presto it found a substantial amount of trojans and other such nasties.

Rebooted, then once again it switched off, only this time I can't get it to switch back on. When I press the power button the blue "lightning bolt" LED flashes, but nothing happens.

I have a similar laptop at home, the dv6000 and I've had the same problems. I bought a new power lead which let me boot it up but then it stopped again.

Is there anything I can do? Or was it pretty much the last nail in the coffin? Seems quite common for this model to short out on the motherboard

just to state the obvious, the battery was on 98% before reboot so its not flat. All of this happens whilst running on battery power, just plugged into mains but no change – user155695 Nov 23 '09 at 15:02
    
Let it cool down and then try to power it back on. Does it turn on after a break? – Marcin Nov 23 '09 at 15:59

try to take out one ram chip and see if it boot's up.like marcin was thinking, it might be overheating. – mike Nov 23 '09 at 17:28

Ok, after some digging on HPs website I found a table explaning what different series of flashes denote a problem with. Here is the page; http://h10025.www1.hp.com/ewfrf/wc/document?lc=en&dlc=en&cc=uk&lang=en&product=435618&docname=c01732674

As you will see, the bottom one explains that a continuous blinking Power LED means there is insufficient power.

Not sure why the laptop would be getting insufficient power if it is plugged in to the mains. Unless there is a problem with the power adapter or you are using the incorrect adapter which is not supplying enough juice to the laptop, as explained here.

As doesnt seem to be a problem with the laptop its self, I would reccomend getting another power adapter designed for this laptop.

Hope this sorts out your problem

Try removing the battery and then putting it back in. That got rid of the flashing and started charging the battery again.
