the time which is displayed after boot is not correct. what is the problem

[renethomas]

Hello,
I don't know what my frind have done with his Laptop.
Yesterday he came to me and tryed to explain what is wrong with his Laptop.
He said after he start the machine the first time in the morning the time is set back to xx.xx.2002.
My question is now what is the reason for this Problem.

One importen Point must i say:
He have never insertet the Akku in the hole time (since he have it).
His laptop is about 4 years old....

I hope i had explain clearly what have to say about the problem.
I do this job for my frind because he think i can better english.

Thank you to try understand what my problem is.

Have a nice day

Hi rene thomas and welcome to Club Vaio.

All computers have a hardware clock which keeps the correct time while the computer is turned off. This runs on a small battery.

It sound like the battery has died.

Some are easily replaced and some are soldered in place.

What model PC does your friend have?

Hi Blencogo,

Thanks twice for your fast replay
I have never foud this Plan :smileygrin:

Tomorrow i run to my computer-shop and try to get one.
I found the place in this plan by using the search option of FireFox.
part 210 ....... (do you mean this one?).

Do you think that this battery is the reason?
Must it be a orginal sony-battery?
Or can i use a battery which looks exactly like sony?


Have a nice day

Hi again,

No I don't think that is the correct part - it is a part for the door to the main battery.

You need THIS SONY RTC BATTERY - but I can't find it on the diagram.

Thanks for your service time
