Macbook 2015 will not power on - screen black - force touch feedback working
Hi all,
Looking for some help with my Macbook 2015 12".
Currently I am stuck at the stage where the device will not power on and does not display anything. No chime on power either.
The problem.
Here is what I have discovered so far.
- The force touch seems to be the only way I can tell the machine is powered on. When clicking on the touchpad, I receive a force touch back.
- I can hold the power button for 5 seconds and the device will power off. I only know this as the force touch stops working.
- I have tried resetting SMC (ctrl + power) and PRAM (option + command + p + r) - does not seem to make a difference.
So here I am stuck.
Here is what happened before shutting down. As a side note, this is the second time this has happened and I can only associate both times to finder crashing. The last time I managed to get it working again by leaving it in power on mode (force touch pushing back) overnight to let the battery run down. Put power back in and powered on. It then booted as normal. Obviously I don't want to have to do this again / every time and I think finding a solution to the below might resolve this.
Possible Cause
Before shutting down, my finder crashed. I believe this was caused by a network drive that still appeared mounted and in /Volumes, but was no longer accessible as it was not on the same network. Office share to home network, of course it's not going to see it.
I attempted to force reload finder. Finder would not behave as normal and not open up.
I opened a terminal and force unmounted the network drive from /Volumes using "diskutil unmountdisk force /Volumes/drive"
I could then click open new window, I would then have to select "Window > (new window name e.g. Documents)"
It would then bring that window to the front and I would have access to finder again. Network drives had disappeared from the side.
The computer appears to work as normal other than that. The only finder issue is it would not bring Finder windows to front when clicking on it.
I attempted a shutdown, Desktop closes but the dock stays. It hangs at this and does not shut down, requiring me to hold the power button to hard reset.
The first time this happened, I could not shut down using Finder. I opened up a terminal window and ran a shutdown command, but did exactly the same thing.
I will see if the machine powers back on when it runs out of battery again. But this is not overly helpful or productive to be without a computer for this long. Especially considering how long it takes to eat through the battery.
Any help appreciated. Thanks.
