power on button light

by georgev5 / August 3, 2012 6:06 AM PDT

When I turn off my Dell XPS 8100, the power button light simply blinks when the computer turns off. I usually then turn off the overall power to all devices. Then I can return power to all devices and the power button will start the computer as usual...

The issue is that when the Power Off procedure is executed, the light on the on button is supposed to go out when the computer powers down. There should be no light when the computer is off...

Maybe it's set to sleep rather than power down?

Thank you for your input. I checked Control Panel power options. I still have Default... I tried to specify "turn off computer" when "Start, turn off computer" is requested but the white light still remains on after the computer stops running. So I left the 110v. power on the computer all night. I think that if it went into Sleep, the computer would turn itself off after some hours... Didn't happen. White light was still on in the AM.

Didn't find a document on a white light.

But the fact it works fine is a bit of a stumper. Hope it's in warranty.

In sleep mode, it does not wake up and shut all the way down. I don't want you upset with me about not knowing how PCs evolved and the differences between sleep, hibernate and a full power off.

Should Dell have such in the manuals?

Upset with you??!! Never!! I think I am having multiple problems. I had to switch my mouse because I could not get response with previous one. Now at least I can control the cursor on web sites... I will look further into sleep, hibernate, etc but I don't think that is the problem because all this happened suddenly on this computer running satisfactorily since May 2010. Thanks for your attention.

HEY THAT'S A CLUE!!!

Changing the mouse along with possible installation of mouse drivers or software can result in power down issues.

I must have missed that. For a test run, unplug the mouse and use the keyboard to shut down/power off (hint? Control + Esc, arrow keys, tab key, then enter when you get what you want highlighted.)

Some progress... I found that I had some time left with Dell so I called... They had me do a few things which did not isolate the problem completely. Finally, this AM I found the white light on even with the computer unplugged... The problem was a new hub (being a "minor" device, I forgot to mention I had added recently). The power from the hub was keeping the white light on.... I don't know if there are hubs which isolate the computer from their own generated power.... I still have outstanding problems but will maybe open a new thread to talk about these. Meanwhile, the Dell rep who thought that it was my power strip that was somehow preventing the computer from completely shutting down said that she will call back. I will tell her about this as well as additional problems.

Those hubs are just like

Those new USB wireless mice that stop a machine from powering down. I can't see the machine so I can see the connected things. But it appears you are getting good help!
