Help with dead laptop?

I have an HP Pavilion ze4300. Dead...
If the power supply is plugged into the wall, the green led indicater is soild green and bright. If I plug it into the laptop, it gets VERY dim and blinks spartically.
And the laptop will not turn on. It appears the battery is fully charged as it lights to 100% when you hit it's test button...although while plugged in the wall NO lights come on at all.
What can I look at enternally to maybe be the cause?

 

For starters try removing the battery, plug the laptop in the wall and see if it will come on with the battery out of the loop.
It's common for those batteries to have a dead short when they go bad.

 

I have tried that suggestion...remove the battery and try straight from the wall. Same result. Laptop does not power up, no lights and light on transformer dims and flashly with no particular pattern.

 

You could try a diffrent power supply and see if that helps otherwise it sounds like a dead motherboard.

 

Could broken power switch make it appear dead?

 

Scott or sparrow (Mike) might be able to confirm this, anyway...

The other day I got some second-hand power packs for the scales at work. I wanted to check that they were working so I tested the voltage with a multimeter. The voltages turned out to be quite accurate for their specified output. The amperages were way over, although they were being tested without being "under load ".

I am just thinking that if you did not have access to another power supply, you could test it with a multimeter.
