I've got a 2009 820-2530 A1278 MBP that doesn't see the hard drive. Normally when these come in and the hard drive is still good it's the 821-0814 interconnect cable that's gone bad. This is the first one I've seen where the drive is good and the interconnect cable is good but the system still...

We're working on an early 2011 A1278 Macbook Pro ( 820-2936-B ) that was brought in for light liquid damage. There was no corrosion or any signs of actual liquid contact to the board. We did replace the keyboard. The device boots normally except it almost immediately starts to appear very...

Does anyone know where I can get my hands on a schematic and board view for a Microsoft Surface Pro 4 / 1724 ? I've hunted all over the place and can't find any mention of either one anywhere.

I'm working on a Mid 2010 MBP 15" 2.66 i7 with the NVIDIA GeForce GT 330M that randomly reboots throughout the day. The crash report has the ominous "GPU Panic" as one of the first lines. I can't seem to remember where I saw it but I'm pretty sure there was an older post about how reballing...

Does anyone have access to these tool packages and maybe willing to share, sell, exchange for a jaunty show tune sung off key ?

I had a 2010 MacBook Pro 17" come in the other day with a memory issue. Easily figured out that the bottom memory slot is intermittent and after a few minutes the machine would freeze or reboot itself or toss the dreaded 3 beeps if any memory module was in there. I did verify with several new...

I'm working on a late 2011 A1297 17" MBP where one of the fans doesn't spin. The fan will move very slightly back and forth but not spin. The fan is actually good, it seems to be the power going to the fan from the connection on that side. The good side is kicking out 4.2v while the...

I'm working on a Early 2015 Macbook Air A1466 that had very minor liquid damage to the keyboard 2 months ago. The keyboard was replaced and all seemed fine until it came back today and it wouldn't charge. Using genuine apple magsafe 60w charger it would react and shows the charge icon on the...
