Keeping time has always been a problem for computers, as their internal clocks needed something to synchronize with. If you have an Internet connection and use Windows, you can get the time adjusted regularly using a time set function from Windows online. The CMOS battery will have little to do with time settings, unless it goes bad. Then, not only will your date and time go out of sync, so can many other settings in the CMOS. So, unless you are getting a low battery warning, or both the date and time are out of sync, you probably don't need a new CMOS battery and replacement probably won't fix you time drift issue.
In Windows 10, to get auto time sync, go to "Settings", then select "Date and Time". Under this you will see an option to "Set Time Automatically", as well as to select your time zone.
<p>The CMOS battery is named after the Complementary Metal
Oxide Semiconductor power. The CMOS has the current date and time functions for
desktop and laptop computers. It allows the computer to automatically adjust
the time, even on computers that are disconnected for long time. When a
computer no longer has the date and time and forget it on every boot, the CMOS
battery probably needs replacing. Some computers have messages when the battery
is weak, while others just lose the current date and time after each shutdown.<br />
<p>Time & Date Errors<span> </span><br />
<p><span> </span><br />
<p>1. Turn on the computer. Look in the task bar at the bottom
right. Make sure the date and time is set correctly. Double-click the time and
click the up or down arrow to switch to the correct time. Click on the arrow
next to month to change the month. Click "OK" when finished.<br />
<p><br />
<p>2. Turn off the computer. Wait 3 to 5 minutes and start the
machine.<br />
<p><br />
<p>3. Look on the taskbar to see if time was lost and said a
strange date January 1, 2000. Replace the CMOS battery, if this is the case.<br />
<p><br />
<p>CMOS Error Message<br />
<p>1. Look for error messages like "CMOS checksum
error", "CMOS Read Error" or "CMOS battery failure"
when you start your computer. These errors are caused in the machines shut down
for several months or when the CMOS must be replaced.<br />
<p><br />
<p>2. Let the computer on for 24 hours. Restart the computer
and find the error.<br />
<p><br />
<p>3. Change the CMOS as the return error.<br />
This is usually a very short and sweet step to complete.
After you have changed the CMOS battery over to a new one all you should have to do is go into BIOS set the date, the time and the year. Save the settings in the BIOS, exit and restart the computer.
You have to set the date, time and year in the BIOS first then change it on the desktop.
The proper battery to use for CMOS is a C2023 coin cell battery.
The CMOS (BIOS) battery keeps the computer'a comfiguration and the Date & Time settings in the CMOS (BIOS) chip in its memory. When the CMOS (BIOS) battery is flat these configuration information is lost. Replace the CMOS battery with a new one, in most cases this battery is a lithium 3 volt battery type CR2032 and it is coin size battery 18mm in dia.(check it to make sure the type of battery is installed on your motherboard). When you replace this battery then go into the BIOS and set the Date & Time etc.
click start control panel date and time you can make your adjustments to the date and time from there or right click on the date and time and you should seeAdjust date and time tabhope this helps
Hi Good day!! That error maybe cause of your CMOS battery it may be not working, replace your CMOS Battery (2032 3volts), after you replace it with new one, set your date and time setting according in your time zone.
When a laptop/computer prompts for a BIOS date and Time setting every time you boot up, this indicates the BIOS battey is flat or nearly flat. This BIOS battery needs to be replaced and the BIOS Date and Time setting needs to be configured etc.
The 161 CMOS error means the CMOS/BIOS battery is dead/flat and needs to be replaced.
The 163 CMOS error means the Date and Time could not be updated when you change the Date and Time setting. This is caused by the flat CMOS/BIOS battery.
When you replace the battery with a new one, the BIOS will go back to the default settings, go into to BIOS setting (press F2 when you boot up) and change the Date and Time, then save and exit.
