I posted this in the W7 forum, but maybe this would be a better place for it. My apologies if this is against protocol.

Hello,
My DSL connection through the ethernet port disconnects when my screen shuts down. Is there any way to set it so that I stay conected even after the screen shuts down? I like to have the screen shut down after a few minutes of inactivity to save power. I'm using a new Lenovo thinkpad T400 with windows 7. Thanks kindly in advance!

DSL is supposed to be an always-on connection. It exists (theoretically) as long as the system is capable of receiving power and the appropriate software is installed.

<<I like to have the screen shut down after a few minutes of inactivity to save power.>>

Are you just shutting down the monitor...or are you shutting the entire system down...in your power-saving efforts?

If your broadband connection terminates, I would say that you are closing the system down.

Are you using hibernation/standby?

Thanks. It disconnects when the computer sleeps, yes. But it also disconnects when only the display shuts down (I have that set to do to save power) and the computer is still 'awake' -- hard drive still spinning. It may actually be disconnecting when I hit a key to turn the display back on -- I can't tell.

What you're talking about is the Ethernet card is going to sleep.

Here's what you do.

Go to control panel.

Look for Device Manager

Look for network adaptors

Right click your Ethernet adaptor.

Look for and click Properties at bottom of menu.

Look for Power Managment tab.

Uncheck "Allow computer to control this device to save power" Then click OK.

You should be good to go!

Thanks a lot for the suggestion, but I tried that and the problem still persists!

Update to what I have tracked down about this problem:

My DSL connection (which needs name and password initially to connect) gets disconnected, not when the display shuts down, but AT THE MOMENT THE DISPLAY STARTS UP after it has shut down. In other words when I move the track pad or hit any key, to start up the screen again, my DSL connection disconnects, and I have to 'redial'. I'm assuming this is from a momentary loss of power (?) to the ethernet adapter/port on my laptop, a new Thinkpad T400, running Windows 7. Anybody have any suggestions?

I have also posted about this in the Windows 7 forum; I'm not sure which forum is appropriate. If this is against protocol, I do apologize!

Thank you!
