When Your Computer Will Not Keep Time, Replacing a Mother Bord Battery.


One may ask, why would I change the battery on my PC, and many of us don't even realize that there PC has one but believe it or not your computer would not be the same without it! .

The battery on your computer motherboard is responsible for feeding the configuration memory, or CMOS, and to feed the real time clock of the computer, the one that show the date and the time.

You can bet it's time to change your battery when your computer is giving one of the following error messages when you turn on your computer.


CMOS BATTERY STATE LOW
CMOS SYSTEM OPTIONS NOT SET
CMOS TIME AND DATE NOT SET.
CMOS CHECK SUM FAILURE

Another indicator of a low battery is a clock that, after being set, runs well while the computer is on,but shows the wrong time when the computer is turned on the following day (it is late).

The motherboard battery can be built using three different technologies:Nickel-cadmium (NiCd), NVRAM (Non-Volatile RAM) and Lithium (Li). The Lithium battery, which is a round one (the size of a coin) and can be easily found at watchmaker's and computer parts stores, has long been the most used type. To buy one of these batteries, all you have to do is to look for a model CR2032.

Replacing the motherboard lithium battery demands some care, it is important that you have your computer turned off, unplugged, and that you have gotten rid of any static build up you may have (you can do this by touching a metal object that is grounded or wearing a anti-static bracelet that is clipped to a ground).

The lithium battery may use basically three socket types: socket with upper tab, socket with lateral tab, and the socket into which the battery stands instead of lying.


While the replacement of the battery in the socket with the lateral tab or of the one that stands is simple – all you have to do is draw back the tab using your finger or a small screwdriver and replace it.

Replacement of the battery that has an upper tab covering it demands extra care. In this type of socket, if you raise the metallic tab to replace the battery, it will lose its pressure and will not make contact with the battery anymore,damaging the socket. In this case, the correct replacement of the battery in done pressing a small plastic lock at the side of the socket with the fingers or using a small screwdriver. That will allow the battery "to slide" laterally, not damaging the upper tab.

Congratulations friend! you have successfully fix your computer! Rest easy in the rewards of your efforts and smile smugly with the knowledge that you have saved yourself cash.

Good Luck and happy Computing!

How to change battery on asrock k7s8x motherboard


A coin-cell battery (CR2032) usually powers the real-time clock and CMOS memory. The battery is 3 Volts, 3/4" in diameter and has an estimated life of three years. When the computer is plugged in, the standby current from the power supply extends the life of the battery.
Just open the desktop, locate the CMOS (Coincell) and remove using screw driver. Replace the battery with CR2032 or an equivalent one.The following brands are used interchangeably for this item: Energizer (ECR2032), Duracell, Panasonic, Eveready, and 3M etc, which can be purchased from any local electronics store.

GoodLuck!
Dont forget to appreciate the solution if I could have been of any help!

Motherboard timer is not working properly


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).

An indication it is time to change the motherboard battery is receiving one of the following error messages when you turn on your computer: CMOS CHECKSUM FAILURE, CMOS BATTERY STATE LOW, CMOS SYSTEM OPTIONS NOT SET and CMOS TIME AND DATE NOT SET. Another indicator of a low battery is a clock that, after being set, runs well while the computer is on, but shows the wrong time when the computer is turned on the following day (it is late).

The motherboard battery can be built using three different technologies: Nickel-cadmium (NiCd), NVRAM (Non-Volatile RAM) and Lithium (Li). The Lithium battery, which is a round one (the size of a coin) and can be easily found at watchmaker's and computer parts stores, has long been the most used type. To buy one of these batteries, all you have to do is to look for a model CR2032 one.

Replacing the motherboard lithium battery demands some care. It seems to be a simple task, but it is not.

The lithium battery may use basically three socket types: socket with upper tab (Figure 1), socket with lateral tab (Figure 2), and the socket into which the battery stands instead of lying (Figure 3).

Fig 14e23e4b.jpg

5671bf9.jpg

Fig 2

While the replacement of the battery in the socket with the lateral tab or of the one that stands is simple (Figures 2 and 3) – all you have to do is draw back the tab using your finger or a small screwdriver and replace it – the replacement of the batter that has an upper tab covering it (Figure 1) demands extra care. In this type of socket, if you raise the metallic tab to replace the battery, it will lose its pressure and will not make contact with the battery anymore, damaging the socket. In this case, the correct replacement of the battery in done pressing a small plastic lock at the side of the socket with the fingers or using a small screwdriver. That will allow the battery "to slide" laterally, not damaging the upper tab.
Whatever the socket used, don't forget that the replacement of the battery should be done while the computer is off.

Times of day clock stopped when i on my inspiron laptop 1525 times of day clock stopped


you are experiecing with your CMOS battery so:

try taking the CMOS battery out
leaving for 30 seconds
make sure it's all unplugged from the wall
do that first
then press the power button after the 30 seconds
to drain all power
then put battery back in
and plug in and turn on

and if still problem remains then you need to change your CMOS battery.

Why litium battery in mother board(intel,asus)?


The lithium battery is use to power up the RTC/CMOS chip which stores the date and time, and some essential configuration settings for your motherboard. If you notice that your computer clock is not displaying the proper date and/or time after you set it correctly, then you may have to change the battery.
