If you lose BIOS settings on startup or your CMOS battery is reaching the end of its lifetime, then the battery must be replaced. This is a guide to replacing the CMOS battery of your computer. In order to replace it, the back cover of the laptop must be removed to expose the cable which secures the battery and the battery itself.
Before replacing the component, please remember to power down and unplug your computer to avoid any power surges or shorts. Failing to power down and disconnect the power cable may result in further harm to the laptop or even yourself, so precautions must be taken.
Note: When the CMOS battery is removed, BIOS settings will be reset to factory defaults.
