MPPro wake up and boot issues


i running yosemite 10.10.4 beta on macbook pro (15-inch, 2011), 2.2 ghz intel core i7, 16 gb ram , 480 gb intel ssd, replaced 750 gb hdd. has dedicated amd radeon 6750 gpu 1024 ddr ram.

after having typical gpu issue replaced gpu , had peace couple of months gpu issue returned. anyway not problem writing about.

asking strange behavior mbpro doesn't wake after being in sleep mode. when opening mbpro screen stays dark, keyboard light doesn't come on. when close mbpro light on front right turn on , stays on , fan starts run after time.

thing can do hard reset via power button. then, when boot screen progress bar , apple logo come up, bar fills 1 fifth , bar , apple logo disappear.
screen turn greyish blue , nothing else happens.

can reboot again via hard reset , run diagnostic test pressing option + d. test finds no issues (neither short nor long version do) , after test can reboot without issues.

works when press option when rebooting , select boot drive (ssd).

know behavior , comes from? come faulty gpu. if yes thought computer boots integrated gpu , switches deticated gpu after boot up?

don't think comes beta 10.10.4.

anyway, appreciate serious suggestions , hints.
 

repair disk permissions seemed help

well, regarding ssd issue running verify , repair disk permissions in disk utility seemed help. @ least now. don't know, maybe ssd starting bad drive space.

there gpu issue. strangely when running hardware test, there no indication of issues gpu.
