    I have a 2017 MBP 13" non-touchbar model.

    Last Tuesday, I left for work with it fully charged. It was running when I left and I just closed the lid to put it to sleep as I always do. When I got to work an hour later I opened the laptop, and it was powered off. I pressed the power button and the fan immediately started spinning full speed. It booted from a shutdown state, but was incredibly slow and the battery died almost instantly.

    I got it home, recharged the battery and then booted it again. As soon as I pressed the power button the fan came on full speed, and it was incredibly slow (multiple minutes to boot, very long freezes when I open a web page, etc).

    The battery icon was gone gone from the bar at the top. When I went to the system preferences -> energy saver to turn it back on, as soon as I click the check, the battery icon would appear for about 0.25 seconds, then disappear again the box would uncheck itself. In that menu it also said the current charge was 0.

    When I closed the lid the fan continued full speed and I could see the screen was still on, so it wasn't going into sleep mode. I tried rebooting several times with no change.

    For the past week, it's spent most of the time shut down but I've used it for a few short sessions though all the problems were still happening.

    I have a genius bar appointment for tomorrow so tonight I was backing up all my files, when it shut down due to a dead battery. I recharged the battery, and when I powered it back up, the fan was no longer spinning and it booted up quickly.

    Any idea what, if anything, is wrong with the machine and what I should say at the appointment tomorrow? I've got about 1 month of warranty left on the machine, so I'm a bit concerned about just letting it go and seeing what happens.

    Sounds like a rogue process try an smc and nvram reset and repair your disk as first measures this may solve it.

    It will be interesting to see what the genius bar people find out. Something is running. My guess is a 3rd party application.

    It was unlikely to by a 3rd party application just because the problem starts as soon as I pressed the power button from a completely off computer, before the computer has a chance to begin the POST.

    Anyway, I had the appointment today, explained to the genius exactly what I said in my original post. He ran his diagnostic and it came back perfect. He said that because of the problem I had, he'd still recommend a system restore which I agreed to.

    So he wiped the SSD, and started the restore, it got to a flashing folder with a question mark and shut down. He said that was normal and just happening because he'd blanked the SSD. But it repeated that way about 4 times and then he said the store wifi wasn't that good so he got an ethernet cable to try again. The same thing happened 2 more times trying to do the restore over the wired network.

    He said because of his diagnostic he's sure the machine is fine and if I do the restore on my own internet at home it should work, but he wouldn't send me home with a bricked machine if I didn't want, so he gave me he option of leaving it for them to reinstall in the back which would take a couple of days. I decided to leave it because I didn't want to get home and find the machine was bricked, so right now the machine is with Apple.

    Does that sound reasonable? That they can't do a system restore over the store's internet and have to send it in but there's no problem with the computer, it's the store internet at fault?

    Well the are sharing a internet connection amount hundreds of devices, so it does make sense. Did you get your laptop back in working order?
