Hi Anak
And thanks to everybody for reply
"Are you comfortable working inside your computer"?
No I am not.. don't have experience but give me clue. I will try to get help from somebody else
So as I see only solution, I should try to replace the bios battery
Well gelaw....This is how I see it....
As you have stated, and fimble has pointed out
I have a home computer for more than 3 years
The average life of one of those batteries is five years.
On computers I have, and had. The clocks would show signs of erratic behavior in the three to five year range, and all I had to do was change out the batteries and that cured my situation.
I did have one situation where the clock froze, and swapping out with a new battery fixed that.
My best advice?
I would go with the new battery as it is cheap insurance. They run $5 American in my area.
It probably is the CR2032 type as fimble has stated, but you need to get inside to check for the number, and whether or not (In very rare cases) it is soldered to the Motherboard before you go and purchase a new one.
No sense buying a 2032, then finding out it's something else.
If it isn't soldered it is just a matter using a non-conductive implement, and lifting it out of the retention ring it is held in.
If it is soldered, and you or your friend does not have experience in electronics, I would suggest taking the computer into a shop to have it done.
It also sounds like you have never had this case apart so it should get a good cleaning inside also.
If after you get the batteries swapped out, and you still have the same problem, then it is time to do the BIOS flash.
My one curiosity is; how is the BIOS clock behaving? But, you would probably need your friend to help you to get to that screen to see that.
If you can not find any one to help you to do this I or another member are only a post away, and will help you, step by step if necessary.
Oh, an gelaw, please see what you can do to fill out your SystemSpecs.
It is very helpful when a fellow member or me know what type of computer we are working on.
