Hi Jim,
Does the clock lose time while your machine is running?
If a computer loses time while it is on, it is not the CMOS battery.
When the machine first boots, Windows reads the computer clock to set the
time. After the machine is running Windows takes care of keeping track of
the time by counting timer interrupts generated from the same oscillator
that runs the system bus.
Try this, from Ken Blake - Microsoft MVP Windows: Shell/User...

If the clock loses time while running, try this:
Open a command prompt window (Start | Run | cmd) and enter the following
commands:
net stop w32time
w32tm /unregister
w32tm /register
net start w32time

Did you set the correct time on your CMOS clock when you changed the
battery?
If Windows displays the wrong time when it first starts, your CMOS clock may
need to be set. You have to access the BIOS to set it.
Or does it seem to lose time when the machine is first booted, like it lost
time while the machine was off?
That is a CMOS battery problem.
You can compare the system time with the Windows clock.
To determine if the time loss is a result of a weak computer battery:
1. Click Start | Run | Type: cmd | Click OK.
2. At the command prompt, type: time /t and then press ENTER.
3. Compare this time with the time that is reported by the clock on the
taskbar.
4. Type exit, and then press ENTER.
If the computer's time and the time on the clock are different, the
computer's battery may be too weak to keep accurate time, and it should be
replaced. For information about how to replace the battery, refer to the
documentation included with your computer.
The time /t command displays the current system time, without prompting
you to enter a new time.

I have put in a fresh battery and the clock still runs very slow. what
else can I do? I got the update to working again, thanks to you.

The CMOS battery, besides maintaining the BIOS settings, also powers the
internal clock or real-time clock (RTC) when the machine is turned off.
System Time and System Date being two of those BIOS settings.

I noticed my clock getting very slow, losing a hour or so per day, so I

problem,
That battery has nothing to do with your problem. Its purpose is to
maintain your CMOS settings when power is disconnected - unplugged -
from your computer.
You have other problems, I'm sure.
