Most laptops require a fair bit of de-montage to get at that battery. If the computer is running while it is removed nothing will happen, until you shutdown the computer and try to start it again. At that point it will have forgotten it's clock and (in most cases) will have reset all Bios settings to factory default.
If you don't change the battery, the battery will die. Your battery is dead when your screen is blank and you have thus lost your CMOS memory. When your desktop computer or laptop starts experiencing the symptoms of CMOS battery failure, it's a clear indication that the CMOS battery, often a lithium battery, is nearing the end of its lifespan.
Once the battery is completely dead, though, the only way to get your laptop running again is to plug it into a power source. When this happens, you’ll probably see a warning message on your screen telling you that the battery is low and advising you to save your work and shut down gracefully.
Your laptop battery is made up of a series of cells that store energy. When you use your laptop, those cells discharge and the battery gradually loses power. If you don’t charge the battery regularly, the cells can become damaged and the capacity of the battery will diminish over time.
If you don’t charge the battery regularly, the cells can become damaged and the capacity of the battery will diminish over time. Eventually, if you let the battery completely discharge too many times, the cells will be so damaged that they can no longer hold a charge and the battery will be dead.
Checksum errors are the most common indications of a CMOS battery failure. The Checksum errors usually occur when a conflict between the BIOS and the CMOS happens. These errors prevent a computer from booting up. Hence, you have to fix the checksum error first if you want to use your computer.
