I get chime, fan and then system reboots on its own
I just got a 2011 15” MacBook Pro and works as described,
When I plug the batt., I get the chime, fans spin, white screen, (no keyboard light) and after some time (+- 20 seconds), the system reboots, (chime) and then shut off.
Only boot if I plug the batt. or magsafe…
This happen with no SSD, with SSD (Sierra with GPu disable), bootable USB etc….
Can it be the Keyboard?
Can I unplug the keyboard connector from motherboard and try with external keyboard? Or should break for parts?
Is dit een goede vraag?
