    I have the same problem, and I think the cause was an overheated AC power supply. I have gone through checking the power circuit through the jack right to the motherboard. I beleive the problem to be a diode right after the connector has gone bad. I checked continuity through the diode and the values are as high as another diode of the same type was checked. I have heard there is a problem with this componet failure on the M2000 board. Has anyone else heard this?

    I have the same problem. I was doing some work on my laptop and it just shutoff. Now I can't get it to do anything whether its plugged to AC power or on battery. I have purchased two power adapters for this laptop in the past 3 years, the last just a few months ago. I'm not sure if the laptop has been ruining the adapters or if the adapters have cause a problem with the system board. The adapters are of the correct specs for the unit

The PC will not power by battery or AC adapter.

Note: As of yesterday I have purchaced another motherboard. After close examination I found a hair line crack on the underside of the motherboard where the DC jack is affixed.

Thank you all for your responses.

Check the power adaptor to see if the power is coming out, as well as there is mains power going into it. The laptop should operate without the battery, if the power adaptor works.

My laptop is Acer Aspire 4520. It is only charging when it is off. I can use the laptop until the charged battery goes low bat and it will shut down. But when I use it with a Power adaptor, it always goes...

If your adaptor is not supplying enough current, it won't be able to run the laptop and charge at the same time.
Try a new adaptor. Cheap as anything on ebay!

I have a Dell D600 (PP05L), its not powering up no lights. I noticed on the power adapter the green light goes out when plugged into ac power. What could be wrong here? please help

Hook up your power adaptor to ac power without it being hooked up to the laptop and see if the green light stays on. If it does then you know your adaptor is okay. if your adaptor is only hooked up to ac power and the green light still turns off then you know your ac adaptor is bad.

Take out the battery from your laptop. Now hook up the ac adaptor to the laptop and if it stays green then you know your battery is bad but you also want to make sure you can get your laptop to turn on. Hopefully it will turn on with only the ac adaptor hooked up to it.

the vr\ery first thing what u have to do is that disconnect the ac adaptor and take the battery out of the computer and then press and hold down the power button without the battery and the adaptor for one minute and then connect the ac adaptor and put the battery back in and then try and turn it on and what u can do is that try and turn on the computer only with the battery and then take the battery out and try and turn it on only with the adaptor,and then what u can try is that try with the different adaptor having same configuration,and try and connect the ac adaptor into the different wall outlet....good luck

No power

Measuring the voltage outputs without applying a load doesn?t eliminate the adaptor as the problem. You also have to know how may amps it can supply as well. To answer you specific question common problems are defective battery, A/C power supply and my favorite?s defective power connector or circuitry inside. When you plug in the A/C power adaptor do any of the LEDs light, up? Does anything happen? Also try removing the battery, plugging in the A/C adaptor and try powering up. If this doesn?t work please supply answers to the above questions plus any other pertinent information you may have. As always please don?t forget to rate the posting but please wait till after we?ve finished.
