I have MacBook Pro 17inch 2011 late.
i had some changes on my mac os lion. my display screen color does no not appear normal.
I erased my partition and I reinstall mac os. but it seems mbp did not reset to factory settings. i have stiill the problem.
how I should reset to factory settings completely?
should I reset my firmware? how?
I would be grateful if you could help me.
Then you have a hardware problem and should take the computer in for service. You cannot fix a defective screen by reinstalling the software.
This not hardware. I had this problem before and they fixed it by reset to factory settings.
Should I erase the whole disk (including GUID partition table)?
I did erase only macintosh hd.
If you tried everything, do it, but it won't work if you did it
i don't know why SMC reset and PRAM reset did not solve.
When last time this problem happened, the technical team said that there is nothing about hardware. they fixed by reset to factory settings. why i can not do that!?
Is it important to do PRAM and SMC reset first, and then erase and reinstall MAC OS Lion?
Is it any difference between reseting SMC by removing battery and (Shift-Control-Option keys and the power button) keys?
I don't know exactly, HOW! but the problem solved!
Thanks for your help.
How to reset factory settings and firmware?
