Setting Can Change To Shut Off Power To USB Buses / When Power Off PC?
Jun 9, 2011
I use my PC for audio production and I have a few external controller devices that are USB powered, for example a midi keyboard. I recently had to build PC due to a theft....long story short after building the new PC I've noticed that my USB buses have continual power to these external devices after I've powered down the PC. My old windows 7 PC did not do this. Is there a setting I can change to shut off power to the USB buses when I power off the PC? Or is this a hardware issue?

I've been having this trouble on my laptop where the power setting just changes at will. I usually put it at power saving when i use it to write but it just takes 10-20 seconds before it by itself changes to High performance.

My computer will not shut down with the "shut down" command. It goes to a screen with message "shutting down" then just sits there. I need to power off manually to shut it down. Once I reboot I can then shut down properly. But after some time of normal use I can't shut down. Are oine or more of my programs leaving some residual piece in place that doesn't stop when I close the program?

Windows 7 home premium pretty sure it is an X64 Randomly shuts OFF not DOWN, then when upon restart (manually pushing the power button) it opens like normal put my login password in and it opens fine then reopens the last program running automatically.

My brother set his max cpu rate to 30% in power options. He says it saves power on his notebook and the batteries last longer. I told him thats a bad idea. But he dont listen to me.

I've customized my power setting so that the monitor is set to turn off after 25 min of inactivity. It was working for a several days but just last week, I noticed that my monitor was not turning off as expected. When I looked in the power setting, the "Turn off the display" was set to NEVER.
I changed it back to 25 min; it worked for a few days....but somehow it keeps reverting back to the NEVER. I should add that I have all the OS updates installed and I am the only user on this computer.

Laptop will not turn off when I tell it to shut down. The operating system seems to shut down, but the computer itself stays on (case lights and fan are still active) and can only be turned off by holding the power button for 4 seconds. I have tried everything short of re-installing the OS - which I cannot do because of the non-transferable programs I have on this laptop. It is a Dell Vostro 3450 running Windows 7 Professional 64-bit.

On a Toshiba LX835 all-in one, is there a way to set Bios Auto On after power outage? It seems like the BIOS on most computers allow this, however, the option is not obvious in the power management section of the BIOS for this model.

I have made sure that the power settings in control panel have been set to "never" under advanced settings. About 4 months ago, windows decided to set my monitor shut off time to 20 minutes. The first time it happened, I figured it was a one-off thing, and set the monitor off setting back to "never". Fast forward 4 months, and I have to turn the setting to "never" every time I start my computer. I've even made custom power profiles, and every time I restart, the monitor off setting keeps going back to 20 minutes.

I had a power loss while installing a windows update about two months ago. Ever since then my system will hang either on logging off or shutting down.I have tried making a new user (No Help)it hangs in safe mode also.I also do not have a list of prior updates in control panel since this problem.The system works fine other than that.

I would like a way to program my notebook computer to 'turn off' not 'shut down' when I press the power button, like a desktop computer would. In Windows 7, there does not appear to be that option available in the list of available options under 'Power options'.

My computer gets at least ONCE BSOD every time I turn it on after a long period of shutdown. It also sometimes randomly just shuts off or give me additional BSODs. It has got to the point that I can't even load to windows recently, which lead me to reformat my computer. I know the drivers here are not the latest ones, I am trying to use only the drivers from the CDs that came with the hardwares because the last time I used all the latest ones it still caused BSODs. I am not sure what other information I need to post up.

I've done a lot of searches using variations of the above title and came up empty or just plain missed the answer.I'd like to know, if it is not asking too much, the following points:
1. What exactly is the function of Link State Power Management in the Power Options Advanced Settings, PCI Express?
2. What are the implications of using the options available:
a) Off.
b) Maximum power savings.
c) Moderate power savings.
d) Which option is the best selection for my Dell laptop.

Anyways, in laptops (gaming or not), does setting the power plan to High Performance actually improve gaming (frame rates, speed and anything else) in battery mode? I'm using a laptop (not dedicated gaming, but suffices) and my games (the recent ones) slow down whenever I'm in battery mode. A couple of friends told me I should set it High Performance, which I doubted since they don't seem to be the type to change the power plan settings and more so with the advanced plan settings.

Over the past 2 years my PC has been afflicted with random power off/power on/reboot events.It will go for months without these and then have multiples of the events in a day. (I had 8 of them 3 days ago.)I assume I have a hardware problem, but nothing has been found and I'm grasping at straws.The time between power off and power on is several seconds.I had assumed this rules out a software cause, but maybe I'm wrong. I know Windows can schedule a power off, but can it tell BIOS (or something) to power back on in a few seconds?I know blaming the power supply is a much more simple explanation, but then I'm left with explaining the intermittent nature of the failure.

My computer wouldn't shut down, even with holding in the power button, and so I just let it run out the battery. Then it wont turn on. I tried holding down the power button to clear out any charge that might be remaining. I have managed to get it back on, but I have to make a connection at the clip where you plug the power button ribbon into the mobo. Also, this is the second time I have had to do this. The computer works fine afterwards...or seems to anyway.

is it very highly recommended to do a registry change - USB Port Remains Active for Disabled or Safely Removed USB Device to power down usb devices like external hard drives after clicking safely remove on windows 7i started using windows 7 recently and the first internal hard drive which i used for external storage on the netbook - windows 7 became unusable after 4 times' usage. Later, I found out about external hard drives still spinning after safely remove or shutting down the computer , on windows 7.i want to protect my other external hard drives so, hence my question above.
No one around me did the registry change as they said that as long as safely remove feature is used, it is enough already despite that the hard drive is still spinning.i hope that i can find at least one person here who is very serious in caring about his/her external hard drives, to give me his/her input.I notice windows 7's usb issue started back in late 2009. I wonder why Microsoft never include its remedy - USB Port Remains Active for Disabled or Safely Removed USB Device in the updates. Is there any bad effect when using the remedy

I am hooked up to a UPS, but when that runs out and I am away, I sometimes need to be able to remotely logon to my computer. Is there a way to get the BIOS to automatically restart the computer after the UPS runs out when the power goes out?

I've changed the setting of maximum processor state on battery from 100% to 50% to save battery. But the setting resets to default 100% time to time. I don't know why this is happening.
