Hola,
yo he recuperado varias baterias de MacBook con NLBA1; algunas con muy pocos ciclos, 2-53.
Es un problema clasico de los portatiles que se usan siempre conectados a la corriente.
Si las baterias no trabajan de vez en cuando, terminan bloqueandose.
Sin embargo, necesitaras tener licencia de reset comprada.

Hi,

I would like to email Louis directly but I cannot find his email through YouTube etc, as expected and I'm not 'in the business' as far as entertainment goes. I have a few questions for him and was wondering if you could point me in the right direction.

Kind regards,

Joshua

Hello, I'm looking for a specific boardview for almost one year and now I found it. But the problem is, it's on chinafix.com and I am not able to sign up. Please if you are able to download this 7z file (or you know someone who has access) and could make it publicly available (or at least just send it to me) I would be very thankful. Best regards https://www.chinafix.com/thread-1265978-1-1.html

Hi,
I have A1707 Macbook Pro with no image output on the internal screen as well as on external monitor using USB-C adapter.
Haptic feedback is present.
When it's connected to the charger (takes 20V)fans are spinning, there is USB activity, keyboard lights up (Caps Lock LED turns on n off) as well as the touchbar. I am able to hear sound when typing.
U9850, U9800 were replaced from the donor board but nothing changed

Good Afternoon, firstly I'd just like to say, I love what you do here at Rossmann repair group and wanted to check out your forums. Can I ask, how do I get access to post on the forums? Or is this a subscription only service? Thank you for your time, Richard.

Hola, tengo un Air de 2015 con placa 820-000165A recién cambiada. El problema es que no carga, no tiene sonido, no va la webcam y observo que la placa viene sin S/N. Será tema de BIOS? No sé que mirar.

Hi
I own a A2551, 2020 MBP and it stopped charging after a software update. Now the battery is all drained, neither i can power it or charge the battery.
When i read the voltage in usb-c ports it pulls something around 5V then machine reverses the current, then sometimes pulls something like 2A then 0.24A.
I can see current is flowing in only 3 out of 4 ports. Does this sound like something you've experienced before?
