Blue charge light rapid blink

[raggy]

The blue charge light on my DV6000 is blinking rapidly but the machine does not charge the battery or power up. What is broken?

[Mumbodog]

Will it power up with the battery removed?

A continuous blink of the power led usually means the power adapter is supplying insufficient power.

No, it does not. With or without batter, same result.

I have even had the socket replaced by a repair shop.

Thanks!

is it possible to measure the power supply, or do I take the chance and buy a new one?

[Mumbodog]

You can use a voltmeter, but this is not always a good indication if it is bad.

I took the laptop to a different repair shop who diagnosed a blown motherboard. They even showed me the burnt insulation between the mobo and the case. repair cost is estimated at £ 330, which is unlikely to be cost effective.

Thanks everybody for your suggestions.
