All-In-One has power, but won't turn on

Microsoft Windows 10 (64-bit)

It was doing fine until all of a sudden it just wouldn't turn on. A light on the back indicating it's receiving power is on, but it seems the rest of the computer won't turn on. I just want to know if this is fixable or not and if it is, how can I fix it?

Sounds like your CMOS battery, which allows your machine to store BIOS settings and keep the internal clock going when power is removed, may be dead. I've had many of my machines refuse to show any signs of life other than a power light when that happens. Sadly, I don't know exactly how you could go about replacing the CMOS battery in an All-In-One like yours as I could not find any guides I could refer you to, but it should just be a matter of removing the rear cover, locating a battery that looks like your typical button cell (think CR-2032 style) and replacing that.
