Finding the CMOS battery on your motherboard is half the battle: It looks like a small silver disc and is usually positioned next to the main PCIe slot. With a light press on the retaining clip, the battery can be removed and replaced. Most newer motherboards use a CR2032 battery, which can be bought for just a few dollars.
Newer laptop models usually have a tiny CMOS battery with wires soldered to it connecting the battery to the motherboard. And in most cases, the battery's well hidden or even located on the opposite side of the motherboard.
All motherboards are equipped with a CMOS battery. In the past, it was necessary to maintain the operation of the CMOS memory, which was responsible for storing BIOS data and other parameters of a personal computer. Previously, BIOS settings were stored in CMOS memory which was powered by an independent power source like batteries.
Find your CMOS battery. It is typically on the right side of the motherboard and looks like a coin. Once you find your CMOS battery, we recommend you take note of the orientation of the battery, whether the + or – is facing up or down. Using a small tool, such as paper clip, carefully lift the retainer clip to free the battery.
Every PC motherboard has a battery. That battery serves two purposes: to feed the configuration memory (also called CMOS) and to feed the real time clock of the computer (the one that show the date and the time).
With a light press on the retaining clip, the battery can be removed and replaced. Most newer motherboards use a CR2032 battery, which can be bought for just a few dollars. But there is also the possibility that your board uses a different type, so you should definitely check this beforehand.
The CMOS Battery. Complementary Metal ... And this can be supplemented by external cache memory fitted on the motherboard which is the Level 2 or secondary cache. PCI slots – The Expansion Buses. PCI stands for Peripheral Component Interconnect and the expansion …
