![]() ![]() Power on/off issues: While there could be plenty of reasons why your computer isn't booting at all, one of them could be a failing CMOS battery.These drivers will most likely be related to the input/output devices connected to your computer. Missing driver: It's also possible that recently installed drivers may disappear on account of a failing CMOS battery.The keyboard and mouse could also stop working altogether, since the BIOS acts as an intermediary. The mouse cursor could become inaccurate, or there could be a delay in the movement. Input devices begin malfunctioning: Since the BIOS is responsible for managing devices such as the keyboard and mouse while booting, they may malfunction if the CMOS battery has been discharged.Usually, the date and time will be reset to a time way back in the past. Incorrect date or time: The most common sign of a discharged CMOS battery is incorrect date and time on your computer.So everything appears to be in order.Your computer will start acting abnormally when the CMOS battery is discharged. Below is an example of the BIOS setup for this computer now displaying the correct time after I manually set Windows date and time on the desktop taskbar. For some systems, you simply need to press the Delete / Del key to enter BIOS setup. You can verify if you BIOS are updated as well on the next startup. This can be accomplished through the Windows taskbar. Make sure you manually set your Windows time and date so that it’s current. Set current time/date: Replacing your CMOS battery will reset your computer’s time and date. Power on / start your PC: Power-on your PC and start your computer as normal.ġ0. Put things back together: Replace your PC case side panel, reconnect cables and power cord.ĩ. Simply apply some light pressure and it should snap securely in place.Ĩ. It has the positive plus sign + flat side up and visible from above. For example, the model shown here is a lithium CR2032 battery. Be sure to keep the positive side up and facing you. Insert your new CMOS battery: Inserting your new battery is usually a lot easier than removing it. ![]() If you are using a tool to pry the battery use caution not to touch any surrounding part of the motherboard.ħ. Depending on your model this can be a little tricky. The tab should just move slightly and allow the spring underneath to push the battery upward so that it can be removed. Remove the old CMOS battery: Release the CMOS battery tab by pushing it away from the battery. Be sure that you replace the battery with the same type/voltage to avoid potential issues.Ħ. Battery types include Lithium battery (as shown in the pictures here, a coin-shaped model CR2032), NVRAM (Non-Volatile RAM) and Nickel-cadmium (NiCd). Locate the CMOS battery: As the image below illustrates, you will need to locate the CMOS battery on your PC’s motherboard. If you plan on doing this without a wrist strap you can touch a metal part of your PC case while you work.ĥ. Ground yourself to avoid static discharge: Attach your anti-static wrist strap and place the grounding clamp to a metal part of the case. Some PC cases have quick access latches or a combination of screws and latches.Ĥ. Gain access to your motherboard: Open your computer case side panel to gain access to the motherboard. It’s always good to invest in an anti-static wrist strap to help avoid damaging your computer.ģ. So if possible try to avoid working in an area with carpeted floors. Keep in mind too, that carpet floors are known to readily transfer static electricity. A good choice is a non-metallic desk or table, like a wood or laminate surface to work on. Additionally, you’ll want to select a workspace to help prevent accidental static discharge while replacing the battery. So in this step take some time to find a location with enough room to work. Move your PC to a Suitable Workspace: Depending on your PC model, you may need to rotate your computer’s case (possibly setting it on its side) to gain easy access to the motherboard’s CMOS battery. An anti-static wrist strap is highly recommended.Ģ. ![]()
