If the time and date is way out each time you start your machine it is probably the motherboard battery.
This is a large watch type battery (CR2032) available from most pharmacy's and jewellers stores.
You will need to remove the side cover of your machine to get access to the battery and change the battery with the power cord unplugged from the wall.

Change the CMOS battery.

If you had taken the time to post the computer manufacturer name, and model number; I would know what motherboard we're dealing with, and what type of CMOS battery it uses.

Generally the battery is a CR2032.
A type of watch battery.

Set computer clock three hours later


Hi buffaloman...
To set your computer clock go to the time in the bottom right hand corner of your desktop screen.
Left click on the clock and a window will open, you will then click on "Date/Time Properties" and it will let you change the time of your computer clock.

Clock not accurate


Hello,

If the clock keeps on getting out - dated, the most probable cause would be the CMOS battery. It is a small circular battery that is located on the motherboard that keeps the time and of your system up to date even when it is turned off. Replace the battery and it should work fine.

Cheers!

Not keeping time


Go into the BIOS by pressing F2 when you first turn on the laptop. In the main screen you should be able to change the time and date. After you do that save the changes and exit and go into windows and see if the date and time is current.

Let me know how it goes.

The date & time on my Sony viao laptop will not stay accurate. Please advise.


This is a good indicator that you have a virus. Your CMOS battery could be dead or dying but that is rather unlikely and once the computer is running the clock should be accurate if that is the problem. I would run a virus/spyware scan ASAP.

I have a e system desktop the clock keeps running late


Computers have an internal battery on the motherboard that helpd the board retain certain data when the computer is off. If the battery is low or dead it will cause this problem. The easiest way to replace the battery is to open the side of the computer when it is off and remove the battery from the battery holder on the motherboard. The battery looks just like a watch battery. Replace it with the same kind of battery (available at most drug stores) once you have replaced it turn on your computer and reset your clock.

CMOS battery replacement


Your Pc should have an Intel E210882 motherboard in it.
A coin-cell battery (CR2032) powers the real-time clock and CMOS memory. When the computer
is not plugged into a wall socket, the battery 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.
The clock is accurate to ± 13 minutes/year at 25 ºC with 3.3 VSB applied.
When the voltage drops below a certain level, the BIOS Setup program settings stored in CMOS
RAM (for example, the date and time) might not be accurate. Replace the battery with an
equivalent one. Figure 14 shows the location of the battery.
These batteries are very common and can be purchased at Wal-Mart, Walgreens, Etc...
Here is a link to the motherboard manual with battery replacement procedures:
