External Monitor Won't Power Off when Laptop Screen does!
Hi,
I have an external monitor attached with an extended display config so I have my laptop screen on the left and a big 24 inch external DELL screen on the right (both displaying different content, the external is my main display).
Everything works well as you'd expect except that when the laptop screen goes to sleep the external screen doesn't, it acts like its no longer getting a signal and displays the self test image that moves around.
This is on a DELL Inspiron 15R Special Edition / 7520 laptop, this same monitor used to power save on the previous XPS 16 laptop.
Any ideas?
Thanks
Dennis

I've been told that its a problem with this model (probably saved a couple of cents in manufacturing costs), it doesn't send the appropriate signal to the monitor over the SVGA port. That and a deficient dell monitor mean that it is not possible to get it working.

Hi,
Welcome to the Community. Which model of the Dell Monitor you are using. Normally a software that goes out with the monitor should have been installed. Its called PowerNap, if you do not have the CD, then you can download it from support.dell.com. Check the below link.

Thank you

Hi,
Thanks for the info, that does look like what I need.
I do have the CD for my Dell E248WFP monitor, I'd already checked that but I just checked it again the disk boots into html text only with no options for installing anything, examining the disk I can see a directory for the driver but can't see any other software.
I did follow your link to " <ADMIN NOTE: Broken link has been removed / replaced from this post by Dell> and that doesn't list my Dell Inspiron 15R Special Edition (7520) under Compatibility. For that matter it doesn't list WIN7 at all, it is 64 bit so I'll give it a go...

PowerNap is a 200 MB monster which took 2+ hours to download! Dell seriously need to at least quadruple the number of servers bandwidth or both. Extremely slow downloads have happened for all my downloads over many days (from DELL only). I'm surprised an app like this is even 1 MB in size let alone 200 times that!
Anyway Power Nap has actually made things worse rather than better, not only doesn't it power off the monitor but when I start using the laptop the external screen hangs and can't even be powered off by the power button. I have to turn it off at the wall to recover.
I have changed the setting to try dimming rather than sleeping as an interim solution (hope that doesn't hang also).

In spite of being only listed at 64 bit its actually a 32 bit app, I found a log at "C:\Program Files (x86)\Dell\PowerNap" called "PowerNapWatcherLog.log"
Anyway that log contains this over and over:

Hi,
I have run out of ideas, were you able to get this fixed?
Thank you

Hi,
I'd since noticed and fixed this issue (video driver issue): en.community.dell.com/.../20134011.aspx
So I tried PowerNap again. It still doesn't work but no longer locks up the monitor.
So issue is unfortunately an ongoing back burner... Are we sure this is not a bug with this 15R model?

Hi,
If I use this tool: www.entechtaiwan.com/.../moninfo.shtm
It confirms my external monitor as supporting "Standby, Suspend, Active off/sleep" etc but also correctly says the laptop screen is a "Generic PNP Monitor" (as device manager confirms) but also that it doesn't support sleep.
1) Should the laptop screen be generic?
2) Has the laptop got confused because the internal one is marked as generic and therefore not able to sleep (after all it does sleep and its the external one which doesn't)?
