I have read many forums that state the Macbook Pro 2015 needs / does not need a battery to boot. I'm not convinced as yet which is correct.
The Macbook Pro mid 2015 I have has no battery and do not really want to buy one just to test.
This model has the newer trackpad which is not clickable when turned off.
At the moment, without battery it does turn on with no display (with backlight), no chime and then turns off after 13 seconds. I see this from the power draw on my DTPS.

Hi everyone, I have a MacBook a1398 emc2910 with an 820-00426A motherboard.
I have a short on the "PPBUS_G3H" line... I traced it to the "U7310" IC

and indeed the IC is shorted between "Vin and VSWH."
On the motherboard, Vin to ground = open and it's OK.
VSWH to ground = about 5,50 / 7.50 Ohms.
With this measured value, can I safely replace this IC or is the CPU compromised?
Do you have any other suggestions?
Thanks for any help you can give me.07-20-2025, 03:35 AM -

I tried using the built-in tool to restore the MacBook (Settings > General > Transfer or restore > Delete) but it got stuck when trying to remove the Find Device configuration (it asked me for the password for my old Apple ID -now I use the same account but...06-27-2025, 08:54 AM -
Hi there! I have not so usual situation...
I have 2015 MacBook Air A1466 EMC 2925 with 8Gb of RAM. It seams that I've killed it by bad SSD adapter. It starts, cooler works... But no chime, screen is black. SMC reset seams works, NVRAM reset doesnt works...
My repair guy has checked all possible. It's all ok with power. The last idea - I could kill EFI firmware... So, I need a firmware of EFI to check it. I have a programmer. But I don't have a similar laptop now to download it and compare
P.S. If you have else any ideas about repair, or you had a similar...12-20-2024, 02:31 PM -
