Question about Compaq Presario 4640 (311300-003) PC Desktop
I have to reset the clock every time i turn on computer. it reverts back to 1997. works fine after reset.
Unfortunately, most manufacturers will not list the exact type and model of your CMOS (Motherboard) battery; therefore, you will need to open up your computer, locate the battery on your motherboard, and record the information about it such as voltage, chemistry, wiring, and packaging. If possible, remove the battery and take it to the location you plan on purchasing a new battery from.You may be able to find replacement batteries at a nearby electronic store like Radio Shack, or online via a Google search.
