What do you mean by "original time"?
This is a short missive on how it works and wear to lay blame: The clock in
Vista picks up its initial time from the system BIOS when the system is
started. After that, it works on its own and does not rely on the BIOS
If it loses time or changes while the system is running, then it is a
software issue - nearly always related to antivirus software, but there are
other causes - and has nothing to do with the system BIOS clock or battery.
If the time changes when the system is shutdown and restarted, then it is
definitely the system BIOS clock. Replacing the battery generally works for
the latter case unless the BIOS is being reset to defaults every time the
system is loaded.
