    i am a computer tech who knows next to nothing about a mac. i have a macbook pro that a guy wanted me to fix as the shop where he took it had it for a month with no results. i booted it from a usb with puppy and saw that the hard drive was not showing up. after some research, i deduced that the hard drive cable was bad, so i replaced it. i then booted into puppy again and the hard drive was showing up, so i fixed it.

    he didn't have the disc, so i unplugged it and sat it aside until he got the disc. when i was going to return it, it didn't turn on. i hooked up the power, and the light turned green, then went to amber. the power light on the front will flash about every 8-10 seconds, like it is in standby. other than that, nothing. all i did was leave it sit for a few days. after about half an hour, the light on the cord turned green, and the battery leds show all green when i push the button.

    i tried reseating all of the cables on the motherboard, took out the ram and switched them, trying each in each slot also, took out the battery, and removed the motherboard and replaced it. i cannot find anything wrong, and do not have any other compnets i can switch out. any suggestions? maybe some known issues, or can it get stuck in standby? i cannot even get to the white screen to boot from the usb.

    yes, i have. i have tried every combination of buttons to hold down and nothing works. i am having a hard time accepting that it just went bad by sitting around for a few days. if this is what a mac is supposed to do, then thank the gods that i don't own one.

    It's really weird that it died just like that! maybe an apple genius can solve the issue?

    not to offend or anything, but if i wanted to pay an apple genius to figure it out, i wouldn't be on here trying to get help from the community. besides, they would charge me a lot more than the $50 i am going to charge the guy that owns it. that's just not good business sense. i am leaning toward a problem with the mainboard, but it could be a battery or ram. i may just take it back to him and charge him for the part i put in, and $30 to cover installing it and gas to bring it back. i just hate charging anything for a repair that isn't finished, even though i have about 3 hours in it right now.
