This happened out of the blue, no previous issues. OS is Windows 10. Apologies in advance if I haven't supplied enough details. Attached are any solutions I found and tried, along with photos (no screenshots so slightly blurry).
The laptop has not been damaged. After updating the BIOS to the latest version found on the support website, the laptop restarted and now briefly goes to the Acer logo, before showing the following sequence of screens:
"The upgrade process has been suspended because the battery charge is too low. Please plug in a power source; the process will continue when the charge is more than 25%"

"Boot option menu" (empty)

"no bootable device - please restart system"

The next step would be to check the BIOS right? Here are the screens of that.

Following this thread, I have checked for eMMC SD references and I think this is present (serial numbers etc still being read?)

I don't think this covers my model, but I have tried this on different stages of the process. I have even drained the battery, tried while charging, and tried again when the battery would definitely have been at near-full capacity.

Following this thread, I tried switching the different UEFI/Secure boot modes. Nothing.

Some threads talk about making a cd for recovery. Is this perhaps possible with a USB? What about 'flashing the BIOS'? Just thinking what else I can do.
Is my drive dead? Am I missing something obvious? Should I go to a repair shop and have them crack it open, see if there's a loose connection? Or should I just call in my warranty and get a replacement
