Gray screen HELP!!

[slim617]

As of right now, i wont have exact details but i hope someone can provide information as of what to do before hand.

So, a while back, i upgraded my girlfriends macbook pro, i believe 2013.
with a samsung 840 pro ssd. i think it was the pro.. i am pretty certain.
But definitely a samsung.

As of recently, she did the most recent update and now it wont load properly.

First it would load extremely slow with the load bar
And now it just loads a grey screen. Nothing else.

i am not familiar with mac or apple. I also dont recall how ive installed any of the things.

But the computer works great, till it was updated.


Could this issue be caused by the third party ssd?
Does it have anything to do with Trim?
What can i do so far to get it out of gray screen?
I dont believe ive ever enabled trim?
how do i check?
Could it be an update issue?


I have been trying to read up on trim and i dont really understand what it is in terms of grey screens or if they have any relations.

I also came across enabling or disabling trim.. causes security issues?

I am really lost and i hope some can ellaborate..

I will provide more information when I actually go check out the laptop

Thanks

If you added a 840 Pro, the latest is the mid-2012 non-retina MBP.

Enabling TRIM will cause a security hole to be opened up as it disables kext signing. TRIM is disabled by default on non-Apple OEM SSDs. If you have not enabled TRIM on it before, then TRIM isn't the reason.

If it's a 15"/17" model from 2011, Radeongate could have hit it.

Have you tried doing a PRAM and SMC reset?

is there not a macbook 2013? i think thats what she has. i am pretty certain.

i will need to inspect further what exactly it is, but because there is a gray screen i dont think anything can be accessed.

What is PRAM AND SMC?

we have tried entering safemode, but that did nothing

what is Radeongate?

i can only find information, but not really understand, but.. does trim or anything cause just a blank gray screen? or anything in relations to that?
-how do i check if trim is enabled or disabled?

There is no 2013 non-retina MacBook Pro, which she has. You may have bought it in 2013, but that does not mean that it's a 2013 Mac.

The current non-retina MBPs with the DVD drives are still available for purchase today, but it's still the mid-2012 model. You still can buy it in 2015, but it's still called a mid-2012 non-retina MBP.

PRAM reset:
Hold down Cmd+Option+P+R during startup, and keep them help down until you hear the startup sound for a second time.

SMC reset:
Plug in the charger.
Shut the MBP down.
Press Left Shift+Ctrl+Option and the power button at the same time.
Release all at the same time.
Then press the power button again to switch it on.

Radeongate is the infamous GPU issue caused by a manufacturing flaw in 2011 15"/17" MBPs with an AMD Radeon GPU.

If you can't boot, you cannot check whether TRIM is enabled/disabled.

Your best option is to boot into Recovery (hold down Cmd+R at startup) and then reinstall OS X from there. All your data will remain intact during reinstallation.

Non of the options above worked, havent tried recovery.

If i cannot check if trim is enabled or disabled how do i tell if that is not an issue?
generally, how do you enable or disable it to begin with?
for recovery, how does that exactly work?
- do i need a disk? (we dont have one)
- is it from a restore point? ( didnt ever set one..to my knowledge, unless it does it automatically)
- does " reinstalling" not work the same as windows? where it formats first?
it is really important to retain all saved files in the hdd
- how do you tell if ssd is fried?

Thanks for all your help! you are the only one who is actually helping i really appreciate it.

tried everything you have suggested, but cant access even recovery mode.

does compatibility issues with a third party ssd cause this?

would this also be considered a dead ssd?

thanks!

The 13" machines have a dodgy hard drive cable. Make sure everything is properly seated and try again.

The cable itself isn't all that expensive, you could always replace it for peace of mind.

If that doesn't solve it then the SSD is likely toast.

I don't think it's a dead SSD (it's very rare).

As snaky69 said, the SATA cable might be failing. To test this, try putting your SSD in an external USB 3.0 enclosure (preferably with UASP - it's pretty cheap). At boot, hold down the Option key, and then plug in the 840 Pro in a USB 3 enclosure over USB. Then when it appears on the screen, select it and boot from it. If it starts up, your SATA cable died.

Thanks for the help! it turned out to be exactly that..

apple fixed it for 60 bucks though =/
