 Hi O Donnell ! 

 

I'm here to help you today

 

You have a "dead CMOS battery" and need to be replaced

it's uses is to power up the BIOS even your PC is turned off

and most uses to save data like date & time

 

 Don't worry about the price    it's very cheap 

 

CR2032 Battery button cell ( most founded on calculators and watches )

You can buy one on your local department stores

 

 

 Hope it helps

This problem is related to the BIOS but not it is not always the CMOS battery at fault, it could also be the BIOS chip itself.

 

CMOS batteries can last up to 6/7 years dependant on how old they actually are when they are first fitted, the type of computer also determines the type of battery and the replacement procedure, not all notebook batteries are the CR2032 type + some are soldered into the MB.

 

Please provide information about your computer, this includes is it a notebook or desktop, is it a custom build or brand name such as Dell or HP, if it is a brand name provide the model name or series number (not serial) providing these details will enable us to better assist you.

Yay! Thanks Captain the CMOS Battery of my desktop PC 

is already drain out of power i put it on my old watch to check if it got power or not

 

I replaced it with a CR2032 battery and seems to be working fine

Yup very cheap indeed 

 

I observed it for 10-11 boot and the error didn't appear again 

 

thank u i'll report back after 2-3 days for more observation

ahh.. hi

 

i brought my LG desktop pc since 2004 so i think its been 10 years

and the CMOS checksum error showed up a year ago and i didnt take action on it

 

about what Captain Lasky said i really think it's the battery because after i replace

the battery it never happen again 

 

but thanks for the advice i'll observe it for 2-3 days 

[phillpower2]

10 years is good for a CMOS battery and is about the max that I have heard them last.

 

Hopefully the issue is resolved and to be sure that it is one final check that you can do is, when you next shutdown the computer for the night, check that the time and date are still correct first, shutdown, disconnect the power from the wall socket and then press the power on button for a few seconds to dispel any residual charge that may remain in the system, if the next time you boot up the system it boots normally and the time and date are still correct you can deem the issue to be resolved.

 

You are welcome btw

Your welcome O Donnell  

 

To observe it properly always check the time & date before

shutting down so you can analyze if it changes or not on your next boot

 

I'm very glad that the issue is resolved hoping the error

would not appear again
