How to Replace Your PC’s Battery All Windows PCs contain a small battery that powers a chip, which experts claim stores important system data known as the CMOS settings.
If that battery runs down, whenever you make an effort to start up the computer you’ll receive errors such as “Invalid system settings–Run Setup” or “CMOS checksum error.” If you aren’t willing to buy a new PC, you’re ready to convey a new battery.
Instructions Things You’ll Need: Restore the CMOS settings
- If you’ve never developed a backup copy of your CMOS settings (by using a backup utility program like Norton Utilities or by printing a hardcopy out on paper), look them up inside the printed documentation for the system or call the vendor of the PC. Restoring your CMOS settings from your backup may help evaluate if the battery could be the problem.
- If you’re using a backup utility to regenerate the CMOS settings, insert the emergency startup disk, and stick to the prompts.
- Use the Setup utility that’s that are part of your PC’s BIOS to re-enter your CMOS settings manually. Restart your pc and wait for a screen that informs you what key or key combination to press for Setup.
- If re-entering or restoring your CMOS settings solves your condition, then it is possible your battery is fine and the settings were corrupted by the virus or some other anomaly.
If, however, your PC “forgets” the CMOS settings you only re-entered or restored once you turn your machine off (and after that back on), you probably possess a bad battery. Locate the dead battery.
- Turn off your PC.
- Before opening your PC case, placed a grounding wrist strap to stop discharging static electricity onto any sensitive components. In fact, throughout this process it’s wise to frequently touch something metal (besides your PC) that’s sitting on the floor, to make sure you discharge any static electricity.
- Open the PC. For most PCs, this entails removing a couple of screws using a Phillips screwdriver and sliding true off.
- Locate the battery on your own PC’s motherboard. This is a trickier of computer sounds because PC manufacturers manipulate many different types of batteries for CMOS settings. The most common are lithium, much like the kind in watches, nonetheless, they are also some AA batteries. Or they are able to look like two cylinders encased in red plastic: a silver box or a red and black box.
- Draw a picture of it, showing its exact position on the motherboard. Remove and replace it 1 Examine the battery carefully to view how it’s coupled to the motherboard. Most likely, the battery is attached with a clip or with Velcro.
Some older PCs may have the battery soldered for the motherboard.
- Unless you’re confident which has a soldering iron, don’t try to replace one of these brilliant.
- After you’ve removed the battery, take it to an electronics mall to complement it using a replacement.
- Replace the new battery in a similar position because of the old one, talking about your drawing (see Warning).
- Restart your PC and re-enter or restore the CMOS settings.
