Gentlemen, I got an old 2014 13" Retina MacBook Pro i5 2.6ghz with 8gb of ram that was not working. No power. Bought a Logic Board from eBay and made sure I got one from the same year: 2014 2.8ghz i5 with 16gb of RAM. All connectors were re-seated, more than once and then... No video. Behavior...

Hi! I just replaced my late 2013 15" MBP 2.3GHz logic board to a mid 2014 2.8GHz (661-00680). The replacement board looks mint, like new. The charging light on the cable works, the fans are spinning up, but I'm getting nothing on the screen and no boot up sound. I tried a SMC reset, PRAM...

Hello all. I am watching a YouTube channel of a third party iPhone repair shop. A very reliable one actually, in Turkey. They published a video a couple of days ago. There is an iPhone 15 Pro, dropped in its case and a screen protector on in that video. No visual cracks, just the screen is...

My MacBook Pro, a late 2013 model, suddenly ceased charging, with the charging cable's small LED failing to light up. Despite purchasing a new charger, the issue persisted. I replaced the charging port, and although the LED now turns green instead of orange, indicating an attempt to charge, the...

I got a macbook air mid 2011 that's running linux and I love the form factor and everything about it but it only has 4gb of ram and that's a small problem for me these days. I was wondering if I could upgrade the logic board to something with 8gb of ram. If I'm correct I could easily change the...

I have an old Mac Pro 4,1 workhorse. It has the ATI Radeon HD 4870 PCIe video card, which occupies the lower two of the Mac Pro's four PCI slots. It tends to overheat in the summer and fail, so I'd like to install a Fox 2 exhaust / extractor fan above it. Looks like the intake of the fan will...

Hello everyone! I have MacBook Pro 13 mid 2012 and it stoped working. No green/orange led on magsafe no fan noise nothing. So I disassembled it and saw this. This TDK 6T216HFA 1205r chip looks kinda burned, so I think it is the reason. So I ask you to answer me two questions. Is it crucial for...

I am attempting to repair my wife's Macbook Pro (A2251). I know that the RAM is bad and I was initially just getting ready to remove and reball the BGA chips. Upon initial inspection I realized that it looked like there were two resistors missing on the logic board (highlighted below). I...

Hi guys, I recently upgraded to a new MacBook Pro because my 2013 model stopped powering on. I had it taken to a repair shop where they changed the battery and looked at it for a while but said the issue was with the logic board and that it would be expensive to replace. I pulled it out of...

I got a MacBook 13 2014 which is working well as I changed the battery out. Since it is in the A1466 model, is it possible to upgrade it by swapping the dual-core 2014 logic board to a 2017 logic board? Will there be no hardware or software compatibility issues?

Will a 2015 Mac Air A1466 logic board work in a 2017 model A1466

I've been using my MB since 2016, love this laptop and still is everything I need. I replaced the stupid butterfly keyboard and the battery back in January and it's been running well. I went to use the laptop a couple of days ago and it wouldn't boot up. Battery was fully charged. I plugged it...

Recently, a client's mid 2011 27" iMac died on him. His repair guy said it was beyond repair & worthless. He was gonna throw it out if I didn't want it. It seemed like such a waste so I said thank you & took it home. Physically, it looks to be in mint condition. No scratches anywhere. It...

Hey all, Quick question if I may... if you only see the first two lights lighting up on the logic board, is that indicative of a logic board failure, or GPU failure? Some background, this computer is a 2011 i7 with a K4100M gpu that was installed about two years ago (had this done by someone...
