I have a 15 - inch Retina MacBook Pro from the mid - 2014 model. Here is the link: https://www.badcaps.net/forum/showth...light=820-3662 . The battery broke some time ago. After I removed the battery and plugged in the original power adapter, the MBP could boot up normally. However, when I checked with IntelPowerGadget, I found that the CPU speed was limited to 0.8 GHz, and it ran very slowly. Later, I found a solution on GitHub. There is an open - source project called cputune that can set the CPU running speed. So I can now run the MBP at full speed. But another problem... -
Hello All,
tl;dr: minimal electronics experience and my first repair, lifted 8 pads off the laptop display LED controller board when attempting a connector replacement, options are attempting pad repair or jump wiring.
Laptop Model: MacBook Pro 15 Mid-2014 Retina, A1398 MGXA2LL/A
eDP Display: Samsung LSN154YL01-A02, assembly sold as Apple part 661-8310
Soldering Equipment: Hakko FX-888D w/ T-18 tips (Chisel, Conical, Bevel types)
I needed to replace the 30-pin I-PEX Cabline connector (labeled J8300 in the Apple 820-3662 mainboard schematics),... -
Hi Guys,
I've got 2.2GHz i7 Logic board for MBP 15" A1398 Mid-2014 MacBook Pro. Received it with no past history. Did some microsurgery to move iSight adapter to it as it came to me with ripped pads for it and no connector. Have been waiting for a heatsink to arrive to start fully testing when assembled..
Everything seems working: booting / charging, however FANS run on full blast (MAX FAN RPMS)
Thought to check what ASD can point out and it gives no specific clue. It goes to certain point and then machine goes to sleep and does not come back on. Adding... -
Hi Everyone!
Will be forever grateful if someone can give insight/direction.
Got machine with liquid damage - Apple MacBook Pro 15-Inch "Core i7" 2.5 Mid-2014 (DG). Wasn't powering on completely. After inspection got the idea that charging IC is blows and couple more places of corrosion (swapped few more components form doner board).
I have a spare working logic board with irrelevant physical damage (just a donor board to me now) Apple MacBook Pro 15-Inch Mid-2014 (IG).
Replaced U7100 (ISL 6259) from it - powers on OK now, though battery... -
Hi Folks,
Just wanted to clear up a misunderstanding of mine (or what I expect is one). Isn't the 12V rail from the 24 pin, EPS and PCIE separated? IE if I put a power resistor on the ATX 12V pin that is not going to load, thus tell me if the EPS or PCIE rails are fine?
I was recently watching ArIs from Hardware Busters video on how to properly test ATX PSUs without using 5 figure Croma substations.
The PCB adapter he used breaks out the 12, 5 and 3.3V pins from the 24 pin and gives you banana plugs to connect to. That is a bit useless is it not? Aren't...
