CMOS Batteries
First, let’s start with a little bit of background on CMOS batteries. A CMOS battery is a small, coin-shaped battery that provides power to your computer’s Basic Input/Output System (BIOS). The BIOS is responsible for booting up your computer and keeping track of time and date. Over time, CMOS batteries can lose their charge and need to be replaced.
If your computer’s time and date are constantly resetting, or if your computer is having trouble booting up, it’s a good sign that the CMOS battery needs to be replaced. Luckily, replacing the CMOS battery on a Lenovo laptop is a pretty easy process.

Method 1:
- Unplug the AC adapter and all peripheral devices from your laptop.
- Disconnect the battery connector from the motherboard.
- Remove the screws that secure the CMOS battery to the housing.
- Gently pull out the CMOS battery.
- Clean the contact points on the battery and housing with a cotton swab dipped in isopropyl alcohol.
- Reinsert the CMOS battery into its housing, being careful not to bend or break the battery leads.
- Screw the housing back into place, making sure not to overtighten the screws.
- Reconnect any cables you disconnected earlier, then reattach the battery and plug in your AC adapter.
Method 2:
- If possible, power off your computer and unplug it from the AC power adapter. If you cannot power off the computer, press and hold the power button for four or more seconds to force it to shut down.
- Remove the service door from your computer. The service door is located on the bottom of most Lenovo laptops. If your computer does not have a service door, skip this step.
- Locate the CMOS battery on the motherboard. The battery might be in a different location depending on your model of laptop, but it will be clearly marked on the motherboard.
- Remove the CMOS battery from its housing by gently pushing it out with your finger or a small flathead screwdriver.
- Wait five minutes before reinserting the battery into its housing. This clears any residual power from the motherboard and helps reset the BIOS settings.
- Replace the service door, if applicable, then screw it into place. Reconnect your computer to the AC power adapter and turn on your computer.
