Have an All In One Wireless computer. There are several wires plugged into the back of the monitor plus the main wire in the wall outlet.
When I open it... it shows a message: "BATTERY IS LOW" .
I thought Battery was only in a Lap Top.
Was told it may be a loose wire.
Any suggestions..?
All the wires SEEM tight.
It is Windows 10. Thanks

There is a small watch battery on the bios on the motherboard. Primarily to maintain settings. 3120? 1.5 volt.

How do I fix this ?

The motherboard battery could be the problem but so could Win10 (it's kind of fussy). The battery is on the motherboard it's about the size of a nickel and can be removed using a fairly small screw driver to push the locking clip back and it will pop out. You have to unplug from the wall and figure out how to get in. Probably by removing a back cover. Did the PC come with Win10 or did you upgrade?

Computer is only 2 months old. Yes, it came with Windows Ten and have Warranty.

Dang! Take it back to the shop you bought it from. If you got it through mail order you should be contacting them for help. If you screw around with it yourself you might void the warranty.
