A few weeks ago, I decided to replace my macbook’s battery - after 5ish years, the only thing about this laptop (the best laptop ever made) was the battery life drained quickly. I ordered a battery + kit from iFixit, and replaced the battery. I conditioned the battery, but every time it discharged it would jump from above 50% battery to 7% battery, then die shortly after (i.e. a very discontinuous discharge). I received a replacement battery for the replace from iFixit, and replaced again. However, I’m still having the same problem with the battery jumps . I figure it’s unlikely to be the battery, but am unsure what else could could be causing the issue. I’ve reset PRAM and SMC.

I used to use SM951 AHCI in Mac Pro 5.1, 6.1, all Retina and Air 2013-2015 but what about NVMe once? Have anyone tried?

My internal hard drive disk has stopped working on my Macbook.

The hard drive is not recognized at boot up, so I get the famous question mark. I tried to connect another hard disk and got the same error message. So I guess the problem comes from the logic board?

When I try to access it from the external bootable drive using Disk Utility I can't see it either.

The disk I'm using is good, and it works when connected with USB (this is what I'm running now). But of course I would prefer to put it inside and connect it with SATA.

Now, I'm wondering what I should do. A new logical board is expensive, and it would be too bad to change it completely, because everything else is working perfectly. So, I'd like to get some advice, maybe for how to check the connectors, change the disk controller or add a new one, or whatever can help to get a more practical solution.

Thank you for your help.

So, when I put my MacBook in the charger and click the on button it went on for 5 sec and then turned off. I pushed the button again and now I could login I looked at the battery it was still 80% so I thought that's odd.

Then when I logged in it shuts off again. I've tried for several times to turn it back on sometimes it didn't even turn on and sometimes it turns on and then it shuts off again after seconds.

I went to a computer store but they didn't know what was going on the guy said that he couldn't find anything weird in my MacBook (software) yes of course when the guy looked at it it worked. Until it suddenly shuts down and I was like: 'Yes that's the problem!' But he had no clue. All he said was: 'send it back to apple'

So another thing: I'm traveling and need my MacBook for my work (I'm a colorist and work in the film industry) I need it everyday.

Maybe something important: last June I Accidentally closed my MacBook with the charger between so my display broke. I replaced it, cost me lots of money, and then after 2 months it was loose (I haven't fixed it yet, been more than one month now)

I can move my display up and down for at least 1cm. I can also detach the black bar underneath the display from the display, think this used to be glued together.

I don't know if this might be the problem from the MacBook shutting down randomly.

Ps. Sometimes my MacBook doesn't shut off completely and the fans start making extreme noises. It's like my MacBook is frozen.

Mid 2015 with Retina display

• 2,5 years old
• Used daily
• MacOS Sierra

I've turned it on again and clicked the D that brought me to some sort of check. It said: nothing is wrong.

Now it just restarts randomly. It's better but still not 100%

So, I need a new card.

• Are all MXM 3.0 B cards compatible or does the card need Apple firmware?
• Would a 6970M card for a Dell Alienware laptop or another card with the same chip as one of the iMac 2011 models work?
• Where can I get a card that works? (<400$)

I've see a lot of questions and answers that dance around these questions but none that actually answers them specifically so ANY help will be greatly appreciated.

• ''Are all MXM 3.0 B cards compatible or does the card need Apple firmware?"
• "Would a 6970M card for a Dell Alienware laptop or another card with the same chip as one of the iMac 2011 models work?'

I found out Apple uses special firmware and for a card to work it needs an EFI flash with Apple firmware.

A card without Apple firmware will simply result in a black screen.

A friend of mine did suggest I could remove the BIOS/EFI-chip from the original board and reflow it onto a cheaper card - but that will probably be too complicated for a lot of people and I already had a new card on the way.

Cards that already have Apple firmware (pulled from iMacs) are interchangeable though - I upgraded from the 1GB 6970M to the 2GB version.

• "Where can I get a card that works? (<400$)"

You can get a working card on Ebay or Aliexpress - any MXM 3.0 card pulled from an iMac should be fine. I paid ~300$.

Lastly, as @mayer pointed out, if you have an iMac 27" Mid 2011 with issues, the GPU is most likely the cause and Apple will fix it if it's no older than four years, because it's a recognized issue.

Apple refused to fix this one because it was sold in 2011 but if you want to fight Apple, maybe that'll work too - I chose to fix it myself instead.

Looking at the pictures below it looks possible....

Macbook Pro 2011 logic board:

Has anyone attempted it?

Tried so far:

PMC-reset

Cleaning the trackpad and its edges with a soft cloth from the top and from the bottom after removing the battery.

Oddly enough, for the first few hours it would go away if I restarted the computer, but would reappear if I adjusted the tilt of the screen. Now restarting, jostling, shaking, etc has no effect.

Photo of defect

Any ideas? I suppose I'll do a little exploratory surgery today and see if I can re-seat any ribbons/cables that go to the screen....I'm hoping I don't have to replace the whole thing. Any tips would be incredibly appreciated....I'm in the middle of exams, and this is not making studying very easy!

Cheers!

For what it's worth, I was just able to fix mine with the help of this list.

For me, the key was trying to start the computer with no RAM installed. After that succeeded, I went ahead and put a single RAM chip back in, and it started up.

What started the problem was the main battery getting too depleted, which seems to have an impact on other parts of the system.

Thanks, everyone!

After that the iMac doesn't boot properly. It does the chime sound, then the apple logo with indicator and then just goes to a white screen. The keyboard doesn't work as caps-lock light wont come on.

I have tried the following:

• RAM reset (Cmd+Opt+P+R)
• SMC reset (unplugged power source for 2-3 hrs, held down power button for 10 sec)
• Removed ram cards and powered up, it did the SOS beep with 5 second intervals, so I'm guessing logic board is fine
• Holding down Option key during startup brings up the disk selector (I have 2 partitions one with Lion and one with Mountain Lion) neither boots up.
• Tried booting from an external Mountain Lion Install USB drive, it shows up in Disk Selector, am able to select it, but then it stops at white screen
• Ran a thorough Apple Hardware Test off the internet through ethernet cable, took 1:45 hours and it showed no errors
• Tried to run through Mountain Lion Recovery Disk, same white screen
• Entered sIngle user mode (Cmd+S) and ran fsck -fy on boot disk, it gave a few minor errors, so I repeated fsck -fy a few times until it no longer gave errors, still doesn't get past white screen. I'm able to browse the HDD in single user mode using the shell. Then did "exit" and also "reboot" commands, both ended in white screen.

I've looked around and found several guides dealing with this exact problem, but as you can see from the elaborate list above, none of those remedies have worked for me.

Any help is greatly appreciated, I'm on a tight deadline to finish this animation project and this is the only machine I have access to at the moment.

I don't have Apple care nor warranty and there's no Apple store/Genius Bar nearby.

I went ahead and installed 16GB RAM ram in my Macbook. It works fine, except for when I try to run Windows 7 Pro in bootcamp. It comes to the login screen then it stops. sometimes it just comes to a white screen. I think win pro7 can handle 192 GB REM, so what's the problem? Can it be the memory model ? I bought Crucial DDR3 16GB 1333MHz SODIMM for Mac.

Thanks!
