Hi!

Today I TRIED to turn on my Compaq Evo N1000v notebook.
It was not longer time connected to power adapter (battery is missing), I connected power adapter, LED indicates power.
When I hit power on button, LED indicator lights turns off and of course notebook STARTS not.
To get power adapter LED indicator light it needs to unplug power adapter for longer time and then connect - LED indicates power, but hitting power button does again the same...

Whee can be problem?
I found over the web nothing.

MiroBad/FAULTY power port...or the AC adapter has failed...
Ok, how to check power adapter?

MiroYou will need a DC Voltmeter to check the output voltage of the adapter. The output voltage should be printed somewhere on the adapter. For example my Lenovo Thinkpad adapter output voltage is 20 VDC.


I just checked your adapter at Newegg and the output voltage should be 19 VDC.Can help to test 5V USB power connector? Adapter it has.

MiroIf the AC adapter has a USB CHARGING port, testing it does not guarantee 19 VDC at the power plug. Also as Patio mentioned it could be a faulty power port.
Now I'm sure - even USB 5V works not.
THANK you all for help.

MiroI was sure, but it's not true.

I found other AC adapter and tried it.
The same problem - so I think two adapters cannot tobe faulty.

So, it is in power connector like you mentioned...
How to fix power connector?

Thank you for all.
MiroMiro,
Following is a link to a generic video on changing or repairing the power plug (jack) on a laptop.

Here is another video with the jack mounted on the motherboard.

I'll follow one of them and maybe ask anything if I will have problem.
