When network connection is active laptop won't go tostandby/hibernate modes

[kd833]

I have a Dell laptop with Windows XP Home SP2 installed. No matter if
I have either one of the three types of network connections active
(LAN, internal WLAN, or USB WLAN), the laptop will not enter into
standby or hibernate modes. I don't have to disable the network
adaptors, they just have to be disconnected. Then the power saving
modes works. Also, both modes work if I execute them manually either
using the power-off button or sleep button. I had a shared drive and
disconnected but I think I might have a shortcut somewhere on the
desktop that might prevent the modes from executing. Is this possible?
Is a shortcut considered an open file across the network?

kd833,

See of this works.

Go to Device Manager and choose the network connection by double clicking on
it.
Then go to the Power Management tab
Make sure that the "Allow this device to bring the computer out of standby"
is not checked.

I discovered the problem. There's a driver attached to all my network
adaptors called QoS Packet Scheduler. This thing must have been
sending network heartbeats, thus keeping the laptop from entering into
the standby and hibernate modes. I didn't uninstall it I just disabled
it from the network adaptor properties. That did the trick.

Lessons learned: Yet another glich was discovered. I have a mixed home
network of XP and Vista PCs. It seems that the Vista PC was sending
NBT packets to the XP PC having the power management issue. The XP PC
would respond to these packets every 5-10 seconds. Thereby,
interupting the XP PC from entering into standby mode. So I disabled
the NETBIOS/TCP-IP on the Vista PC and the XP PC consistantly goes
into standby. Go figure. I guess I don't really need NETBIOS/TCP-IP,
so I disabled it on all PCs.
