Computer won't sleep

HP Pavilion A6009N desktop
3 gigs RAM
AMD +64 dual core processor
Nvidia 9800GT Graphics
Microsoft 1000 wireless keyboard & optical mouse

Problem - Computer refuses to go into sleep mode. When I force sleep by
clicking the power button on the task bar the computer goes to sleep for
about 5 - 20 seconds and then wakes up and stays awake.

The cause; Installation of a gateway router from AT&T to provide TV and
internet service.

AT&T tech support claims no known issues with this router, yet the
computer slept just fine prior to installation of this router, and if I
power down the router the computer sleeps with no problem. This is not a
solution since the router must remain powered up to provide TV service
to my home.

I have searched the internet for a solution, and have performed all the
steps in the tutorial authored by Brink to no avail.

Looking for ideas., anyone?

Do you have wake on Lan disabled in your BIOS?

 

Do you have wake on Lan disabled in your BIOS? Note it may be called
something different like wake on network.

 

Go to control panel, system and maintenence, system - click on devic
manager. Go to Network adapters and right click on the adapter that yo
use to connect to router. Click properties and go to the powe
mangement tab. CLear the box that says allow device to wake th
computer.

Hope this helps

 

Daniel, this did help, and I thank you. But unfortunately it led to
another problem. When the computer goes to sleep the Ethernet connection
is broken, but when it wakes up it fails to re-establish that
connection. Is there a setting to cause the network adapter to establish
a new connection? A hot restart won't do it, only a cold boot.

Did you check if your BIOS had the same option since the Windows option you
are using is not working.
I am surprised that windows even with a restart does not work. How about
run/cmd/ ipconfig/ / renew?

 

Yeah, I think it may be coming down now to the cable. I have put this
thing to sleep several times and it re-established the connection on its
own a couple of times. This last time it failed to connect and I
unplugged the Ethernet cable and plugged it back in and it immediately
connected. I need to come up with another cable and see if that clears
it up.

If disconnecting and reconnecting the cable works then maybe using device
manager to disable and enable the connection may also work. I don't think
the problem is the cable itself.

 

Curious, I tried your suggestion and no joy. I disabled and enabled 3
times, and nuttin'. Unplugging and re-connecting does it. I can do the
deed in the back of the gateway router or at the net adapter and it will
re-establish the connection. BTW, I tried another cable and it made no
difference.
