[dead CMOS battery]
I WILL open it, but is there any chance I can find the Gateway2000 P5-75
schematics and battery specs online before I do so I can put it all back the same day?

Gateway, P5-75, and probably Gateway 2000, are all ambiguous; you cannot
really tell what the motherboard uses without an exact model number
of the (probably Intel) motherboard.

What you CAN do, is get to Radio Shack and buy a coin cell (CR2032) and
an alkaline 4.5v (#840) and maybe a 1/2AA (#5150) lithium cell, and
after you see the innards and plop in the battery you need, take
the others back to the store for a refund. For ten-year-old hardware,
those three possibilities cover almost every desktop computer.

Two caveats: if the old battery is leaking corrosive goo, you will have
to clean that up. And, the replacement sometimes does NOT LOOK LIKE the
original battery (look for a labeled socket that fits a pigtail on the alkaline
battery, and use the handy velcro on the battery to attach it ... somwhere).


We were junking those machines as too old to use at the factory, last
millennium. I may have a motherboard for one, in a crate full of win
3.1 & 95 computers that got pushed under a workbench. 'Gateway 2000'
was their pre millennium brand name, and on every computer they sold.

I think they used the Dallas RTC module with an internal battery. A
black, 28 pin module that was usually soldered to the motherboard.
