Won't wake up from sleep mode

Genius staff was unsure of the problem. We tried resetting the SMC, sleep mode adjustments to none, once the screen reboots or comes on, it just wants to sleep. They said it could be the battery(battery is over 90%), hard drive and/or logic board. I am willing to repair if parts are reasonable. Any ideas?

Did they even try a different drive and maybe running it external with the hard drive and sata cables unplugged ?




Is there any chance of a faulty closed-lid sensor? I recently had my MacBook on top of another one, and the magnets in the lower laptop triggered the sensor on the upper laptop, making it think the lid was closed. Of course, nothing you do will get the screen to wake when the laptop thinks the screen is shut.

If you have some sort of magnetic influence, maybe the fix could be as simple as moving your laptop to a new location. If not, maybe your sensor has gone bad, and is constantly thinking the lid is closed even though it’s not.

You could try using an external monitor, keyboard, mouse, and trying it all while plugged in. This will bypass the sleep sensor on the lid.
