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?

With the drive installed & connected, MagSafe disconnected and battery removed, press the power button and hold it for a good 15 sec to fully discharge the logic board. Now plug in the MagSafe and quickly press the Shift (⇧) to enter into Safe Mode. Are you able to get that far? What do you see on the screen.

It looks like the folding compression latch has come off the logic board base. It you look you should see a small pin on each side this is the hinge pin =which sits into the mating slot in base piece. Carefully bow the part just enough to get into the the correct placement.
