Please help! MBP 15" 2011 will not boot at all
Hi,
My 15 inch early (May) mbp 2011 will not start up. Here is what I have observed so far:
1) When power button is pushed (without MagSafe attached) hard drive will spin up and about after 3-5 seconds it will turn off (hard drive spins Down, no further boot process) No chime, no led indicator light in front.
2) When power button is pushed (with MagSafe attached) hard drive spins up, keeps spinning, but no further boot process. Just black screen and spinning hard drive.
3) When attempting SMC reset, fans turn to high, and screen remains black, still no boot)
4) Since mbp fails before booting, PRAM/NRAM resetting is not a possibility. (Tried)
5) I have also removed the battery cable from the logic board, and tried resetting without any luck.
6) I entered CD into optical drive - it "ate" it, but will not eject now. (Tried holding eject/left mouse/control e etc) still nothing.
7) After letting mbp rest for 1 day, it booted fine like nothing happend, worked fine for 1 day, then next morning back to square one. Now 5 days later still nothing.
If anybody has any ideas what could be wrong, or have possible solutions, please don't hesitate.
Thanks in advance, Oliver
