Black screen and black Touch Bar

Hey there,

I’m out of ideas maybe you guys have some input for me.

I’ve got a 2017 15” MBP with Touch Bar and all of the sudden it won’t boot - no warranty left.

The thing is: the fans start spinning, the display and the touch bar stay black. Trackpad is reacting (well at least it’s on) but the keyboard isn’t (no green light pressing the caps lock key). Oh and no backlight is on (I can’t see anything if I use a light to check the screen).

I don’t have an external keyboard at hand (no adapter atm) but I’ll try the SMC and PRAM/NVRAM Reset on Monday with one I ordered.

I opened it up but there is no liquid damage - while I was at it I replaced the heat sink thermal paste and unplugged everything to see if that fixed the problem - no luck though.

The odd thing is that the Mac is booting up even when it’s closed and the processor gets extraordinarily hot.

If I force it to shut down by holding the power button it won’t reboot - only if I disconnect the battery and reconnect it.

I’d be happy if anyone could help me out here :)

I’m a little confused - at first you said that your Mac won’t boot, then you said that it boots up even when it’s closed, then you said that it only reboots when you uninstall/reinstall the battery.

I agree with your decision to get a working keyboard and try to perform a reset. If you can, see if you can use the keyboard function button to increase the brightness of the screen.

Well I mean it boots but not really since only the fans start spinning and the trackpad turns on. Also it won’t boot willingly or at least barely reacts to me pressing the power button.
