MacBook Pro early 2011 PRAM

Hello,

when I open my macbook from sleep the screen stays black but the keybord turns on, and then I have to force restart it and do a PRAM reset couple times (CMD+OPTION+R+P), only then macbook turns on and works perfectly, otherwise it loads to a certain point at the beginning and thats it screen stays grey. Any ideas or advises? And no this problem started not when I updated to High Sierra it started with Sierra.

MacBook Pro 15' macOS High Sierra version 10.13.1

Run Apple Hardware Test. Also run Disk Utility and run First Aid on your startup drive. You might need to run it from Recovery HD or Internet Recovery if you can't boot from your startup drive. Also - running Disk Utility from a startup drive can't fix itself, but it can diagnose a problem.

Hard drive or SSD? I've seen issues where a drive was marginal or even corrupted. A corrupted drive can show all sorts of symptoms, including booting up to a certain point and then just shutting down, or going gray screen. First Aid can fix some corrupted drives, but in many cases it can't. At that point the only thing that can be done is either get a new drive or reformat. There are also concerns if there data that's not backed up, because reformatting will obviously delete everything.

How about an SMC reset for good measure?

@y_p_w Well I think SMC reset helped. Loads perfectly tried couple times. Hope it stays like that.

Thanks!

SSD. But the problem is that Recovery HD or Internet Recovery does not load, just grey screen and thats it. Did the First Aid from Disk Utility from startup drive it said everything OK.

Going to try Apple Hardware Test.
