Standby missing totally in Windows XP

[Bill]

My Latitude C400 was upgraded from W2000 Pro to W-XP Pro
last week. After that, the Standby function is missing
from Start-Shutdown and in the Power Option Properties (no
standby and hibernation displayings and options at all).
Other functions, like display, wireless network, and WS
Office, work OK. I have downloaded the latest Bios Update
and vedio driver from Dell website and installed into the
laptop. But nothing changes. I need the standby to let the
machine sleep when I close the lid.

A funny thing is if I reboot the laptop at the docking
system, the Standby comes back. I set the Power Option for
standby when closing the lid. (No meaning to set it when
works on the dock with an external monitor.) I click Start-
Reject from Dock (same as sleep or standby), then pull off
the laptop from the dock, open the lid, the machine works
OK. After I close the lid and reopen it, the blue screen
shows up, and the machine reboots. After reboot, Standby
is gone. Our IT technician has worked on the issue for a
long time and could not fix it. Dell supporting also
cannot give me much useful help. SOS. Thank you who can
help me in advance.

Hi,

The problem stems from a non-compliant driver. It may be certified for
WinXP, but in conflict with another. I would assume they've tried installing
the most updated ones. It may help to install an older version instead.
Which driver? I don't know, it could be any driver that causes this, but
video and nic drivers are especially suspect.

Rick,

Thank you for the rapid response.

I failed to find the driver that may causes the conflict.
The problem (no standby) will be gone if I reboot the
computer on the dock. Can you get any clue from that fact?

I really appreciate your time.
