Display getting slower to light after mouse or keyboard activity

RknRusty · 28 Jun 2015

I searched sevenforums.com for similar cases, but all results involved resuming from sleep or standby. In my case, the power options are set to "never sleep" and "turn off the display" after 2 hours (I changed it to never turn off until this is resolved). When it first started it was a few seconds. Over a couple of weeks, it's grown to 7 minutes or more. All works well after it finally lights the display.

I believe you can see my system info, Win7 32, single user home desktop of the early Win7 era. No upgrades or fiddling has been done, I gradually gave that up after W7 came along. Possibly not listed is a Logitech USB wireless mouse that has worked fine for a year or so. Sometimes its driver is using a lot of resources during the display-off condition, but stops immediately upon waking up. This can be seen in the CPU history in Process Explorer, which I frequently check before starting to work with the computer. The only recent new equipment is a new cable modem.

I did notice there were two sessions of CMD.exe open, and I'm not sure I've noticed that before. I usually back an image every Sunday night, but I think I'll postpone this week's until I work this out.

Thanks for any ideas.

Update:
After 8 hours with the display set to not turn off, nothing has gone glitchy with my computer. It's ready to go as soon as I start any work. I don't know if that's any sort of clue, but I figured I should add that observation.

I checked the task scheduling in Norton Security and see nothing that might be different when the display sleeps. In fact I can think of nothing that should "care" whether the screen is black or not... except the video circuitry. I hope my hardware isn't failing, I don't want a new computer. This has been the most trouble free system I have ever had, and that dates back to my 8088 days.

I've decided to go ahead and run the weekly (Acronis)image backup tonight. The reason I was hesitating earlier is that my external drive has only room for one at a time. I'm aware that if the computer ever goes blooey during the backup, I'm up the crick. One of these days I'll get a big drive.

So are you saying that your monitor powers off and then takes up to 7 mins to power back on? That would be a monitor failure probably capacitors in the power supply or deflective florescent bulbs not starting up. It is probably cheaper to get another monitor unless you can fix it yourself.

Hi, Indiana, thanks for the reply.
No, the monitor doesn't power off. The pilot light stays lit and the screen just goes black. I can manually turn the power off and it lights instantly when I turn the power back on, no matter how long it was off.

Here is a picture of the settings in Power Options where I usually set it to turn off the display after 2 hours. But it does not kill the 120v power, just the display signal.

You have to try it on another PC to make sure monitor is alright.

I have a little XP Netbook I can connect it to. I'll get around to that this week and report back with how it goes.

Yep, the monitor is toast.
Thanks,

Bummer

Did you try with the same cable by the way?

Ahhh!, "headslap smiley" Lol
No I didn't. And I went out and bought a new AOC 22" for $109 bucks. After I installed it and confirmed it was working, I tried the old cable, and yes, it works fine, even when I wiggle it.

I love the new one. That extra 3" is a lot.
I saw some that advertised the ability to display a screen with video from multiple applications. None were in the size/price I needed, and as far as I can tell, this one does not. That would have been very useful for me. Oh well. I still like it a lot.
Thanks for all of y'all's input.
