MacBook Pro is just dead

My Macbook Pro does not start (boot) anymore, no sign of life at all.

What I tried so far:

1. pressing the power on button in various combinations with the cmd, ctrl and shift buttons (as suggested on some websites)

2. removed the battery, pressed the start button for at least 10 seconds and replaced the battery

3. removed the battery and tried to start without battery (but with the battery charger connected)

Doing a battery check (pushbutton at the left side) rusults is no leds lighting when the battery charger is disconnected and all leds lighting when the battery charger is connected.

Any help is appreciated,

Rik

Knowing the exact year/model would assist us with getting specific info for you.

Check the power adapter voltage with a meter. Perhaps it has failed.

Can you borrow another adapter or charge the battery in another MacBook ?

Rik. Thanks for accepting my answer but its a little premature if you are not up and running. Now I have the model no ill see if I can't give you more specific advice. Are you willing to put your Mac apart to investigate?

由完成的

Ok, I "unaccepted" the answer.

As long as it can be reversed I am willing to disassemble the Macbook.

Thanks, Rik

Did your MagSafe only light up with a dim green light?

Mine shows only a dim green light with the battery in or just the AC. The battery lights are all off. Do you think your fix would work in my case?

I had no LEDs lighting when running only on battery and all LEDs lighting when running on the AC power supply.

But if you have the screwdrivers, the resistor and a voltmeter at hand it takes less than half an hour to try it.

Anyone else in this situation can try this, to verify if the battery is the culprit (on older Mac models with removable battery):
