Hi,
After I shutdown my laptop, it booted by itself. But has only gone up to the BIOS. And keeps looping back there. My device is an Acer one 10 (2 in 1, where the screen part can be used as a tablet and the keyboard dock is an external HDD). The bios (v1.007.x32) is limited, and Aptio is version 2.17.1249

I've tried fiddling with the limited options on the bios setup utility, but obviously that hasn't worked. I've only been able to force shut down by holding the on/off button. I've seen some forums suggest to enable CSM, but as my bios is limited I don't have access to it.

I'm also wondering if it could be a hardware problem. This laptop has had a history of the battery burning the motherboard (but it was under warranty then).

Thanks in advance for any help.

I'd suggest these free bootable diagnostics:  http://www.carrona.org/initdiag.html

The MemTest86 (NOT the MemTest86+) will boot to the UEFI

The hard drive diagnostics won't (and, unfortunately, I suspect the hard drive).

 

You'll have to locate a UEFI bootable drive that can run hard drive diagnostics.

I have an ISO for this - but it's over 700 mB in size.

If you're interested in downloading it, let me know so that I can upload it for you.
There'll be 2 versions - and both are experimental - they've worked on a few systems, but didn't work on the last one that I tried it on.

 

If you can't do that, then the only other option that I can think of would be to try another hard drive and see if that fixes the problem.

Unfortunately, I don't even know if this system can be worked on outside of the factory.

I'd suggest posting over at the Acer support forums for more expert advice.

I put this up in the Acer forum as well, and the response was that it's possible the integrated storage is gone or inaccessible, and that only Acer could fix it.

I'd still like to try doing those diagnostics to be sure. This laptop has no CD's slot, so I'll use a USB. Do I load it with the UEFI ISO first then the memtest86?

Also, do you think it's worth to try discharging the CMOS battery? I've read in other places that it helps reset the BIOS.

There's many different ways to do this, and I'm not an expert at any of them.
The first thing is to try Rufus:  https://rufus.akeo.ie/

Read up on how to create a bootable disk for an ISO on a UEFI system

 

Discharging the CMOS shouldn't hurt the system if done properly - so give it a try and see what happens.
