I only recieved this RL85 yesterday. I did a clean install of windows 10 on a 2nd HDD and the main 1TB HDD to be used as storage. All was working well. I installed all the drivers. Then installed the BIOS update from the website.This worked fine and i shut down the machine. Since then my BIOS is showing 0 for the RAM and any changes I try to make to the BIOS won't save! Have I just been really unlucky and got a faulty RAM slot or CMOS chip or is this a BIOS issue? I looked at reflashing the older BIOS but I can't do this as I can even choose a DOS bootable USB because I can't save any changes in the BIOS! I have contacted ACER for a repair as I suspect a hardware failure but I would be grateful if there is a better solution. Due to the design it isn't like I can take the RAM stick out to check it!
