Where Is The Cmos Battery In An Acer Extensa 4420 Laptop? How Do You Replace It.
My laptop is losing time and the CMOS battery needs replacement. I am unable to locate where this battery is. I would also like to get a free service manual as I already have the user guide.

CMOS battery usually looks like a coin. Round, flat and silver lithium battery, similar to wrist-watch battery, only larger in diameter. It is usually placedin black plastic seat near the BIOS chip.
I'm not familiar with Acer motherboard layout, but it is a standard thing among PCs.
Some motherboards have different kind of battery that looks more like a capacitor than a battery. And it is soldered (sort of), so you won't be able to replace it without some electrician skills.
