Macbook mid 2009 A1278 Problems

[Steveb1471]

Hi

I was wondering if somebody could give me some advise on what to try next in relation to a boot issue i am having with my Macbook pro

At present my Mag safe light will report fine, orange charging and green charged.

When i press power i can hear the macbook pro boot for roughly 8-9 seconds (no display) it then cuts of and restarts in what can only be described as in some sort of hibernation mode. No hdd activity, no caps lock light, No display. Fans are on

I have tried :

Enter Recovery - Command + R
Reset NVRAM - Option + Command + P + R
Safe Mode - Shift
Apple Diagnostics - D
Apple Diagnostics - Option + D
Power Cycle - Holding power button for 10 seconds

I have also reset SMC

None of the above did anything

I have changed the Ram with no success.

I have unplugged battery and tried to boot just of Magsafe with no success

I have uplugged trackpad and tried to boot with no success.

I am really running out of ideas and am starting to think about logic board failure or CPU failure, but it strange that i get a green light and spinning fans.

Logic board is 820-2610, no obvious signs of board damage, however i am not a component level expert.

can anyone give advise to what else could be issue?

Many thanks

Steve

i've seen things like that before.

can you try reseating the memory?
also is this a 13" or a 15" MacBook Pro?

Hey homie!!! I have dealt with this exact same thing and was able to get my 2009 Mac Pro working well. I downloaded a program called “GFX card status”. What’s happening that’s causing the random restarts is this: you have 2 graphic cards in your Mac, the low quality card is faulty in some of the ones from that year, and when it tries to switch over to the high quality card, the system crashes. What the “GFX card status” program does, is allows you to choose “Intergraded Mode” Which keeps the HD graphic card In use and reduces random restarts by 90%.

The OP can't boot so the gpu utility can't be used until the MacBook has booted.
