I received a question recently from subscriber Arjun Reddy, who had power-saving problems with his laptop:
Hi there Terry !!!
Lately, I’ve run into this issue where my laptop’s display doesn’t get turned off for some reason I’m not aware of.
I triple checked the power options for any other advanced options I can get help with, turns out that my laptop’s display doesn’t get turned off although I set the option to turn off display after 2 minutes of no activity, while to dim the display after 1 minute(s).
Let me tell you something here, there’s this application, ‘uTorrent’ that always runs in the system tray and the other VoIP phone application, “Majic Jack” which is pinned to the taskbar.
Please advise on this and pass your suggestions for any settings to be tweaked.
By the way, my OS is Windows 7 (32-bit).
Thanks a ton.
I wrote back to Arjun to say that it sounded like he was on the right track — it was probably something that he was running.
If it blanks and then comes on later, it’s probably something scheduled to run.
He mentioned aprogram that was "pinned to the Taskbar", but that shouldn’t cause any problems. That is the term Windows 7 uses for a program shortcut on the task bar. His problem would have to be something that was running.
I suggested that he check your video driver settings. Even if he didn’t find anything there, he could try reinstalling your video driver to solve a corruption problem or a priority/sequency problem between the driver and something else.
But, I really think it was something that was running, either an application or a service.
Of course, it could be a byproduct of malware. Or a hardware failure. etc.
I’d give it a try as you suggested, re-installing video driver.
But, tell you what, last night my display got turned off and I was pretty surprised.
I think you’re damn right about some application running in the background and meddling into my display settings, point being, last night my VoIP device, Majic Jack (USB port with a soft-phone application) had its firmware upgraded automatically (that’s the way I set it to auto upgrade).
I’m pretty sure this is the culprit in my case, however, can you please tell me how is that I can narrow down to the application or service causing interference with the power options, that way, I can re-install, upgrade or uninstall that particular application when I next run into this issue.
I doubt if it’s a byproduct of malware as I’m using Vipre, and I totally trust your recommendation on this.
As always, thanks for your time and thoughts.
I wrote back to Arjun to say that I’d like to know a way, too. I asked him to let know if he found one.
And, he did…
I’ve figured out a way for this and would like to share with you 🙂
Here we go with the steps I followed.
1. Open up cmd prompt window (has to be run as administrator)
2. Type “powercfg -energy” (once the analysis is complete, it generates a file)
Problems in the analysis are categorized into ‘errors’, ‘warnings’, ‘information’.
3. It’s under ‘errors’ we get to the see the culprits causing interference with power options like display, sleep, etc…
(You might download the word document which talks more about ‘powercfg’ from the same page)
That said, I’ve got one last question for this week.
How is that I can bypass the login welcome page as I’m unable to, although no password is set and the account type is ‘administrator’.
I’d not prefer my intervention to hit ‘enter’ at the login page.
Please help me solve this.
Thanks for your time and thoughts.
For this last "problem," the answer is one that Arjun won’t want to hear — he should set a password and use it, even if he is the only user of his computer.
The point is, if he is the only user, he needs to be the only user — the password becomes one more layer of protection against access from the Web.
