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,
Это хороший вопрос?
A history of the machine might help.
the macbook worked fine for years, some days ago I left it in working order, when I returned one hour later it was dead.
