Just open the case, pop the battery out and go buy a replacment. It's not hard to remove/replace it and you should see it pretty easily.

How to verify that the CMOS battery needs to replace


<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 />

Am having hp g6 laptop and i forgot my password,so how can reset my password


Holy Cow a bios password?

Did you try removing the CMOS Battery?

You'll have to remove the CMOS battery. Most laptops require you to take the laptop apart to get to the CMOS Battery. It will be a silver battery about the of a nickel on the motherboard. The most common is CR2032. Also sometimes the battery will be in a vinyl covering and have a cable that attaches to a port on the motherboard. Whichever type you have you'll need to either remove the battery or unplug the cable and let the laptop sit for an hour or two. Then put it back, reassemble the laptop and reboot the laptop. With the CMOS battery out the computer will lose the date, time and password.

If removing the cmos batter does not remove the password you'll have to go to the manufacturers website and look for the manuals. See if the manual references how to reset bios. Most likely you'll have to short the jumpers or pull a pin.

It sounds like the CMOS battery(s) are dead. They hold the most recent boot information including current date. Assuming both machines are on the older side, it's entirely possible the CMOS batteries no longer are providing enough power to retain this information.

My date has to be reset every time I turn on my computer. How do I ensure the date and time is memorised thereby avoiding resetting. Thank you.


most of the cases the main reason behind the date time reset problem occurs due to weak CMOS battery on the motherboard. So, you just need to change your CMOS battery on your motherboard to resolve this problem.

The time always changes whenever I turn the computer off. How do I get it to stay current?


Sounds like your CMOS battery is dead on your system. The is the Real Time Clock battery or RTC (CMOS). Your system needs to be opened, if it is a desktop, open the case and look for a disc shaped battery, remove and replace with the appropriate one. You will then have to get into the systems bios by tapping F2 wgen the computer starts and resetting the time and date, then once windows boots, you will have to reset the time and date in windows, time zone etc. If you have a laptop, you will have to find the type of battery that is installed and do the same procedure when installed.

How to solve CMOS checksum and timer errors?


Hello,

Your backup battery is to weak to save the cmos data. Open your computer case and look for a round silver battery that looks like a quarter. Remove it and go to Radio Shack or a drug store battery section and get a replacement. The battery number is probably CR2032 but may be CR2025 or CR2016. insert the new battery and power up your computer, this time when you set the time and date the settings will stay when you turn it off.

I hope this helps, If so please rate our solution.

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.
