Did this start recently? Does the machine remember the date and time? Have you run the Dell diagnostics?

sure sounds like the BIOS battery is going bad. i don't suppose you've got a spare?
 
if i remember correctly, it's located under the mem cover on the btm. (i'm working on a c610 right now and it's under the kybrd)

That's a very strange problem, especially considering that the Service Tag is stored in non-volatile memory on the motherboard. It shouldn't be affected by loss of (battery) power. You may want to try replacing the CMOS battery as suggested, but I'm a little doubtful that this will fix the problem.

Just for kicks, try updating the BIOS to the latest revision, if possible.

Hi. Thanks for your advice.
First I will try to replace the bios batteries.
Is the Bios batteries called "Reserved Batteries", which are linked by several button batteries?
Second I will try to downgrade Bios version,
Now I am using A23.
Thanks again.

The batteries are often several small hearing aid/watch battery cells linked together, with a plug extending from one end. They usually come in a black, green, or yellow plastic shink casing.

The Asset utility for laptops is not the same as the one for desktops.
The utility is dell internal and not released to the public.
Only dell certified techs can change laptop service tags.

The Asset utility for laptops isn't exactly a secret, despite its being labeled "INTERNAL USE ONLY." Every time I've had a Dell tech work on a laptop, or received a motherboard replacement, I've gotten on of the CDs containing the Asset utility with the /s switch. It shouldn't be too hard to get a copy...
