Vista wakes itself up from sleep

Sponsored Links

When I put Vista to sleep, it usually wakes itself up, often after only a
few minutes. A low-power feature isn't worth anything if it won't stay in
low-power mode.

When Vista wakes itself up, powercfg doesn't give any useful info:

C:\stuff>powercfg -lastwake
Wake History Count - 1
Wake History [0]
Wake Source Count - 0

The System Log has this entry:

Event ID: 1
The system has resumed from sleep.
Wake Source: Unknown

and whenever Vista wakes itself up, the Event ID 1 entry is always preceded
by:

Event ID: 104
The service is publishing to the network.
Keywords: Event originating from the fdrespub service
Source: Resource Publication

Is there a way to prevent Resource Publication (whatever that is) from
waking Vista up?

Thanks,
Sam

You might try going through this troubleshooting guide to see if will
help narrow down the cause. Check the Network Device to see if that is
waking the computer up. (Step 5)

Resource Publication can be turned off using System Configuration (in
Administrative Tools).
