ASUS ALL IN ONE computer ET2221i-b85 The time is not correct and keeps losing time. I want to replace the cmos battery .


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.

How do I fix my CMOS Battery Low error so I can correct the Time and Date since it's stuck on the 01/01/2004 date and won't save in my BIOS?


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.

Hope this helps

Chek smos errer


You have described you problem incorrectly. I guess the error mess is "CMOS Cheksome error. " I guess.

This messenger comes due to following situations.
1. CMOS battery low. Check for the CMOS battery (most commonly CR2032) power if it is low this message can appear.
2. BIOS has been reset on purpose or by a fault. Set time date and other settings.
3. Motherboard problem. Rarely motherboard will have this issue with CMOS or with the battery powerline making it to lose CMOS Setteings. Change the motherboard or live with it.

When to change CMOS battery?


You will need to change the battery just when the computer says something like this "System CMOS checksum bad - Default configuration used" or also could say something like "CMOS battery low", etc. That's the time to change the battery.

Got message "CMOS battery low" What steps are


Assuming you know how to get into your computer and identify the CMOS battery, you just need a pair of tweezers or similar to remove the battery. Once it has removed, take it into a drug store or pharmacy and find the exact same battery, and replace it in the motherboard. If you can't identify the CMOS battery, please let me know and I can help you with that.

Every time i open my laptop, I had to press F1 to load the windows, and I think I read, cmos battery is low. I have to change the date and time everytime I turn on the laptop. Is it really the CMOS...


Yes the cmos battery is the problem, the laptop must be dis-assembled right down to the motherboard where the battery is located in order to fix this issue.
