My 17 in MacBook Pro does`t turn on...

My MacBook Pro wont turn on, i was working with it at the afternoon and i put it to sleep, i tried to turn it on .... nothing happened i tried all the diagnosis but none of it worked, resetting the PRAM and the other trouble shoots but my mac does`t have reaction for any of them. I heard could be a problem with the flat cable or maybe motherboard issue...?

Thank you

When the battery drains all the way down on this model it will not start till it has about a 15-20% battery charge. Try leaving it plugged in for a while. You can even press the power on button and walk away and it will boot after it has enough charge. Check the test button on the battery and see what you get.

I had the same problem with my MacBook Pro. It is fairly common. You Tube it, there are plenty of videos. Mine started for 2 seconds and shutdown. An apparent mother board issue. If it is still under warranty send it in. If not, you have nothing to lose, so try this. I did this today and my MBP is now working like new again.

There are also plenty of videos on youtube that show exactly how it is done. It sounds kind of scary, but mine was no longer under warranty and I really had nothing to lose. One problem I did have is that I didn't seat the RAM back in properly after I put everything back together, so there was about a half an hour after I did this, that I didn't think it worked, but it did.

It's kind of amazing, but makes sense if you think about what it is actually doing. softening the solder to close up the broken connections.

Good Luck!

Hi All,

I took my mac to one of the mac store today in Ft lauderdale...they checked it out, the logic board has failed, probably caused by the Nvidia card...They will replace it free of charge...;-)

I`ll get back with the resault, maybe it will help someone..

Thank You
