The only way for me to turn it on was to plug in the MagSafe connecter (which only showed the green light).

I then asumed it was a problem with the replacement battery (from eBay) and put back the original battery.

For some strange reason, the original battery wasn't recognised either!

I've reset the PRAM and SMC, but still to no avail!

I would greatly appreciate your help!

I have a late 2011 mackbook pro which battery indicator showed not working/replace battery soon, replaced the battery with one I bought from ebay. When installed worked as it showed to have 60 % change out of the box, I went ahead and charged it fully and then it drained after a couple of days and would not recharge. Waited a couple of days, it charged a 2nd time and this time i did SMC reset and calibrated as suggested. After the 2nd charge ran out, it started to drain fast and would not charge while plugged in. Replaced with the old battery, charged one time and now back neither old nor new battery will charge, megasafe doesn’t light up at all. Any suggestions?

I turned it off, everything seemed normal, but the next morning it wouldn't turn on again. It won't even start up: absolutely no sound, as if it was completely dead.

I checked the battery indicator and it was completely charged. I opened it up and disconnected the battery, plugged in the MagSafe charger, and there was still no response. I plugged the battery back in and no response. Plugged in the charger and connected the battery and no response.

I took out the hard drive and all my info was there; it would mount on a different MacBook Pro with no problem, and luckily I got all my files backed up.

So I know the hard drive is not the problem. The fan won't even move when trying to turn it on.

I tried taking out the RAM, one by one, no RAM at all, switching them from slot to slot: no response.

Tried out all of the key combinations on the keyboard as well... still nothing.

I don't know what else to try. I read somewhere that the on/off button is connected to the ribbon cable from the keyboard. I checked, and it is plugged in correctly to the logic board. I'm afraid my logic board is dead, but after only a little more than a year????

Any guesses?

Thanks for your help.

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.

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!

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!

I have a MacBook Pro with a RAID 0 SSD setup so I can have a fast IO, worked like a charm for years...

Now I would like to upgrade to High Sierra and the installer informs me that: "You may not install to this volume because it is part of a AppleRAID.".

Is there any way to get around this?

If I do a clean install can I make a bootable APFS RAID?

Around two days ago I was about to move my workhorse to the kitchen, to do some culinary research (read: how to boil potatoes) when my MacBook just turned off when I disconnected the charger. I've had this problem before, which went away after a short while by itself. I just pinned it down to magnets or magic. After a while of being mildly annoyed by it shutting down, I began testing the battery in TechTool, which gave me virtually no information save for the fact that the battery is just maintaining its charge, but not actually getting any.

The battery indicator shows a 100% charge, as does Coconut Battery, which should mean that it's not the SMC. I did an SMC and PRAM reset, though it's unclear if it did anything at all. I'll try an SMC bypass and see if that does anything at all and update on this.

Logic tells me that it's the I/O board which is fooling around, but given my current financial situation, I don't want it to be. So, bottom line, is there any way to be completely sure that it's due to the I/O board, and/or any good way to fix it? Any help will be very appreciated and will hopefully help others in the future too.

For the sake of clarity, I'll enclose two Coconut Battery screenshots for future reference.

I'm looking for answers regarding the new Samsung 860 EVO 500 GB 2.5” SATA III SSD compatibility? Does anyone out there try to install this new internal hard drive to an old late 2011 MacBook Pro?

I assume I'll need an upgrade hard drive cable like the one who installed the 850 EVO but what else should I know to upgrade my laptop to an SSD internal drive?

I am wanting to upgrade the logic board on my MacBook Pro 13" (Mid-2010) with the one from the MacBook Pro 13" (Mid-2012). Both laptops have the same model number (A1278). By upgrading, I wish to increase the processor speed, maximum RAM, graphics capabilities, thunderbolt and have USB3.0 capabilities.

Essentially I want to put in this:

MacBook Pro 13" Unibody (Mid 2012) 2.5 GHz Logic Board

(although I'd try to find the i7 2.9GHz model)

And remove this:

MacBook Pro 13" Unibody (Mid 2010) 2.66 GHz Logic Board

Does anyone know if this upgrade would be possible? Would the new board fit correctly into my old MBP body (screw placement etc)? Will all the other connections will be the same (LCD, Battery, Fan, SuperDrive etc etc) or will I need adapters/converters. If so, it wouldn't be worth it. But If the two boards are directly interchangeable without any serious problems, this could be a nice upgrade and would breathe a few more years of life into my laptop!

Thanks in advance for help!

Does anyone know the location of the power on pads on the (13 inch mid 2012) Mac book pro.?

When I play a music or other sound and set the volume more than 3/4 of max volume, I hear disturbing rattle/cracking sound especially when playing music with great bass. Rattling sound most likely come from left side but when I drag left-right balance to full left or full right, Rattling sound gone. Someone can tell me what happen actually with my mac? Is it really blown or this is usual problem?

Thank You

It originally came with 2x4gb DDR3, and I replaced with 2x8gb DDR3L, as advised by a friend and after checking several online foruns.

About 6 months later the macbook died and I had to get the logic board replaced.

The thing is: "the guy" at the repair shop said the ram was probably the cause, because using a low-voltage ram on the system originally designed to use DDR3 ram caused the system to have "extra energy running around" and it fried the logic board.

I checked around online in all kinds of foruns and didn't find anyone talking about it. Lots of posts says it's fine to replace DDR3 with DDR3L. My friend still uses his macbook and nothing happened.

Has anyone heard about this?

The macbook is currently using its original DDR3 ram, but I still have the 2xDDR3L with me and I don't know if I should replace it again.

The next day I put everything back together and tried the keys again and they still didn't work. Everything else on the computer works fine except those 2 rows of keys.

I've been around a lot of forums trying to read up and find out what my next step should be but am not sure. I took the back piece off to reveal the logic board and dusted everything off - I didn't see any water or visible damage. A lot of people recommend completely taking apart the Macbook (eek!) and blow drying everything. I just need to know:

1. If the keys aren't working now, would they even work if I tried that?

2. If it doesn't work, what needs to be replaced? I hear some people replacing logic boards and others replacing keyboards. Are they connected to each other or separate pieces of the laptop?

Sorry if this sounds confusing, but I need to figure out what to do next because I'm really dreading going to Apple with this issue and paying a ridiculous amount for repair (especially if I might be able to handle this myself).

Thanks for any help!
