Hi Peeps.
Just a quick question please as I am by no means an Apple fundi at all.
Can a 'popped' battery cause the Macbook to be completely dead? Client said the battery definitely popped. It doesn't look swelled or anything but it doesn't switch on at all. No lights, no fans, nothing.
Also, using a 85W original Apple charger. That is working for sure. Does it need more wattage?
Don't want to go buy a battery for no reason.
Client is adamant is worked before the battery popped and I can't see any damage what so ever on the board... -

Hi,
my MacBook Pro 15" 2018 Touch Bar (A1990) doesn't charge anymore. Board# 820-01041-A

The Macbook was charging when suddenly the "charging sound" appeared every other second for around 4-5 times.
After that the Macbook was dead. It isn't charging anymore.
The USB-C Port where the charger was plugged is burned. Also The Cable and the... -
Hello there
I have problem with Macbook Pro 15" 2017, model 2017, MB code 820-00928.
I bought it as broken with some artefacts on the screen, first I thought that this is problem with ribbon cable but after inspectiing ribbon cable I know it is fine. I tried to reinstall macOs and then I figured out that this must be something with GPU as installation freezes at the end (when drivers are loaded). I installed Windows and was able to install every each of drivers except GPU driver, as soon as I tried to install GPU driver - black screen and restart.
