Hi all,

 ACER AZ5600-U9002 will not post. No beeps and screen remains black. PSU is good and RAM is good. CPU fan spins for a few seconds then stops. I see it has no CMOS battery. My guess is that the BIOS is corrupted
I am wanting to know if there is any way to flash the BIOS with it being in this condition?

 Also, if the CPU is bad could it cause the same SITUATION as described above?Replace CMOS battery.  CR-2032, available everywhere.Where is the CMOS battery found on this machine?There must be one, because it says this in PAGE 113 of the manual, but I have looked at all the disassembly PHOTOS and can't see where it is

Random Loss of BIOS Settings
If the computer is experiencing intermittent loss of BIOS information, perform the following actions one at a
time to correct the problem.
1. If the computer is more than one year old, replace the CMOS battery.
2. Run a complete virus scan using up-to-date software to ensure the computer is virus free.
3. If the computer is experiencing HDD or ODD BIOS information loss, disconnect and reconnect the power
and data cables between devices.
If the BIOS settings are still lost, replace the cables.
4. If HDD information is missing from the BIOS, the drive may be defective and should be replaced.
5. Replace the Motherboard.
6. If the Issue is still not resolved, see “Online Support Information” on page 175.
