Bios not saving settings.
I've been having a really weird problem with my Acer Aspire E5-511 laptop. The Insydeh20 bios seems to be completely broken. I first realized there was a problem when I wanted to install Arch Linux when, instead of showing the bootable USB drive in the boot options, it showed EFI USB Drive, EFI network boot, and EFI CD boot. when I go into bios and do ANYTHING the settings don't get saved. IF I set everything to default and do save and exit then it just freezes. I've tried downloading the bios install from Acer and it doesn't apply, no matter what I try. I have my computer dual booted with Windows 10 & Ubuntu 17.10.
There is 2 issues with the CMOS idea: One, if it was an issue that the CMOS battery was dead, then the settings would be the default settings, which they aren't. Second, the CMOS battery is soldered to the motherboard, and I do have a soldering iron, but am not too experienced with it and don't want to risk ruining my motherboard if at all possible.
