turn down the power of usb3 and turn it on back via program

Q: turn down the power of usb3 and turn it on back via program

Hello Microsoft team,
We need for an application to unplug and replug usb3 - not physically but with a program.
We checked a lot on the internet but did not find answer how to do it in windows 8.1 pro (in c++).
We know that hibernation creates something alike, but how can we only turn down the power of usb3 and return the power back on back via program (in c++).
Thank you for your help.

Hi

First I am not sure if should post this in this forum or under hardware problems as I am not sure where the problem is coming from.MY apologies if this isn't the correct forum, moderator please move to correct forum.

I own a HP computer and have been very pleased with it.
I am running windows 7 and the processor is an AMD Phenom II.
I have always have pentiums before that. My problem is simple, when I lose power my PC which I always leave "ON", is very hard to turn back on.
I turn it on, turn the monitor on and it will take 2 or 3 restarts or a wait of 6-8 mn to have it back on.
The last time it happened it was so bad, that I though for sure the HD was fried.
I have it hooked to an aging surge protector which has protected several of my PC's for years (Nothing ever fried when hooked to it).
Since I am fairly new to AMD and windows 7 I am not sure what is creating this.

What does this and how to correct it?

Thanks

Patrick

A:PC hard to turn back on after power outage!!!

Possibly a failing power supply. If you want to leave your PC on all the time you should consider a UPS so the PC won't shut down abruptly when the power goes it.

You could try and disconnect the hard drive just to see if that changes how it powers on.

Running Windows Vista Ultimate.

Display turns off after about fifteen minutes regardless of whether I am actively using the computer or not. The only way to turn the display back on is to close and then open the lid. This disconnets me from AOL, so I have to sign back on again, and if I was emailing, I might lose my current email.

Under Power Options, I have 'Turn off the display' set to Never for both On Battery and Plugged in. Under 'Put the computer to sleep' I have both On battery and Plugged in set to never. Nonetheless, the display still shuts off while I am working.

What do I need to do to prevent the display from turning off at odd intervals?

So I have already tried the solutions such as boot up the pc and press shift and such to get a menu and then download somthing on a usb and get into an administrator account.The Administration account I can at least log onto as it's not password protected but I still can't turn on Wi-Fi which basically defeats my whole purpose of using the computer as I use it for gaming. So regarding me not being able to log into my actual account, I've tried resetting my password multiple times without success. I think it's due to the fact that I am not able to connect to any Wi-Fi spots (which I assume is because of safe mode which I can't turn off for some reason) And that brings me to my next point, of I can't connect to Wi-Fi die to safe mode. I have tried to turn off safe mode in the settings but when I press the button for it to turn off it slides back over to the on side. Please let me know if you have any other solutions that I have not tried yet, Thanks !

So this doesn't happen all the time, but every now and then my PC will suddenly lose power. It doesn't go through the shut down process, it just dies. Then after about 5 seconds it starts to restart. It either restarts successfully and loads back into windows, or it does this thing where it starts up for one second, then powers off, waits a second, then starts up and powers off again. It never powers on after that.

I've found out that opening up the case, pulling out the power cable connected to the motherboard and plugging it back in fixes it. Once I do that it starts up next time I try to turn it on.

Here are my specs:

Corsair 16G (4x4GB) Vengeance CMZ16GX3M4A1600C9 DDR3

Once again the computer impaired one comes to the table of knowledge...

I shut down my PC, fans stop, lights go out. About 6-8 mins later it starts up again, been doing this for four days now. I ran a virus scan which came out clean. The only way to keep it turned off is to unplug it. The only tinkering I've done lately is to try to open a port on my router (which I didn't get done, forgot password and reset button doesn't work). I don't think my PC is set to hibernate, I have never used that feature.

Is there something I should check?

Last night, my computer turned off while I was using it. It wouldn't turn back on, and everything else on the surge protector was working fine. Since I've had problems with power supplies before, I turned the switch to the off position, removed the power cord, and let it cool off, in case it had overheated. When I tried to turn it back on, the power light and the LEDs on the inside blinked on and then back off. They were on for maybe a tenth of a second. During that time, there's no sound of my computer trying to turn on or anything, just the lights. Does anybody have any idea what this might be, or where to begin to troubleshoot??

btw, I know I mentioned LEDs, but I don't have any extensive mods, no overclocking, etc. Just pretty lights.

TIA for any help!!

I'm baffled.

Had to reinstall Windows XP. It appears there are issues with SP2 involving the video graphics card and the sound. Now I'm stuck. I thought that if I chose "do not use this device" under "Device usage" on the display adaptor tab, that it would pick the right adaptor.

Anyway, my screen went blank and I tried to reboot in safe mode and it sticks at mup.sys. I disabled mup and it now sticks at "nid" something or other.

I got the bright idea to use "Windows Narrator" to try and reenable the adaptor but I think the reinstall or the SP2 killed my sound.

Now I'm really stuck. Is there a way to reenable VGA adaptor from the command prompt in recovery mode?

Recently when I installed the GTX 750 Ti into a pre-built PC (HP Compaq 6000 Pro MT) the PC would not boot. After leaving the power supply plugged in after I tried many times to turn on the PC the fans started to run at max power. Now whenever I plug in the power supply the fans run at full power the disk drive works and whatever is plugged into the PC like a keyboard or something it works. But when I press the power button the computer does not boot. I've tried to uninstall the GPU and it won't boot. I've unplugged everything from the MB. I never shocked the computer either.
 

A:After installing GPU PC will not turn back on.

The GeForce GTX 750 Ti graphic card uses 60W and requires a minimum of a 300W power supply.
The HP Compaq 6000 Pro Microtower PC has a 320W power supply.

I don't believe insufficient wattage is part of the problem.
It's my guess you damaged something or didn't properly seat the graphic card or didn't properly connect it to the monitor.

Hi, a few weeks ago I came home a few hours after having used my computer in the morning to find it off. It would not turn on. I unplugged everything and took off the side panel and found the PSU still warm. I read around on similar postings on this forum and decided it was my PSU. I bought a new one. Still didn't turn on. However, the f-lock led on my keyboard was lit up when the switch on the PSU was flipped on. So I e-mailed my motherboard company, Epox. I recieved some directions that would get rid of electricity still in the board such as holding the power button down for 10 seconds, setting the cmos to 2-3 for a few seconds and putting it back onto 1-2. One of the directions was to remove the round cmos battery, which i did not do because I was unable to reach it enough to remove it. I also took it completely apart and replugged everything in. No such luck. So, I bought another mobo, one just like it but the chipset was nforce3 250 instead of nforce3 ultra. Supported the same hardware, though. Still will not work. So, now i'm wondering if it's the power button on my case. I am probably going to plug my friend's case's power button into my mobo and see if it turns on.
>>>>To summarize-
1)Computer mysteriously turns off.
2)Buy new PSU.
3)Fiddle around with old mobo, but end up buying new one.
4) Still will not turn on. And when I say won't turn on, i mean nothing turns on, moves, makes noise, or lights up.

An easy way to troubleshoot the case power switch is to completely disconnect it from your motherboard. Then take a regular screwdriver, and just quickly touch (short) the two pins that the case's power switch usually connect to.

Hopefully your system will fire up, and you'll know you have a dead power switch!

A:My cybershot won't turn back on

Sony camera problem.

This could be happening for several reasons. The camera could have a software /firmware fault, or it could be a problem with something preventing the lens from moving as it should.
But it's just as likely to be the Li-ion battery not holding a charge as it used to.
If you have a mains adapter, try that instead of the battery, see if it works then.
You may need to buy a new battery, as they don't last for more than a couple of years, especially with heavy use.
If you can get the screen on using the mains adapter, go into the menu and do a 'factory reset'. Take the memory stick out first.
All faults are repairable, but you would do well to get a quote first, as a new camera may be cheaper, (unfortunately).
The pictures on your memory stick are not affected by camera faults, as a rule, but if you have another one, try it, just in case there is a problem with the edge connector on it.

Hi,
I've just recently had this happen, but I've been here enough to know I may have contracted a nasty.

Last week my system started hanging up and plain not responding. My wireless aircard refused to work in a manner like it was telling me that it was already in use, when it wasn't even plugged in! I couldn't get much to work right so I rebooted in safe mode, ran a couple of scans, which found nothing, rebooted in normal mode and my aircard was working again. Yay.
It worked normal except for the Windows pop up box that says you are offline kept popping up, and I couldn't close it unless I connected to the net via my aircard. Now my AVG has been switched off and I can't get it to turn back on, and my surfing via aircard is noticably slower. And, my power icon in the tray has gone away.

I have a Toshiba Satellite P-105, 32 bit processor, Vista Home Premium, SP 1.

So I have an ASUS P4C800-E motherboard in a system that a built a few years back. It worked fine but the system has been sitting in my basement for a year or two unused.

I decided to take the components and drop them in a new case.

I have hooked everything back up properly (i think) but when I hit the power button, the cpu fan, power supply fan and case fans turn on for a brief second and then shut off. (the green standby light on the motherboard is on)

What do I do?

I think you can tell from my question I am exteremly amatuer at this. Simple explanations please...
 

A:Turn power on... fans start up then power shuts off in 1 second

With it shutting down after 1sec, I would check that the hsf is plugged in and working. If there is no fan input ie fan speed, most boards shutdown. In addition that the hsf is installed correctly. If it is loose, etc you will have problems. Most of the time when the hsf is loose, it shuts down in about 5~10sec not 1sec. I tend to think it is more of a shorting problem of the board to the case.

If that is not the case, I would attempt to pw ON the system outside of the case. There are complete instructions in a guide at the top of the forum. It is called troubleshooting guide for problem builds.

I recently upgraded Windows 7 to Windows 10. When I power down the system from the menu, my computer does not completely turn off. The procedure I use is described below:

Click Windows_Start_button > Power > Shutdown

The system closes applications and appears to initiate a shutdown procedure. Everything appears to be shut off, but my mouse is still lit up. I do notice that the fan stops and everything else appears to be completely shut down. When I was running Windows 7 before my upgrade, my system completely powered down.

I have a dual boot system with Linux, and when I power down from Linux, the shutdown is complete, so I don't think I accidentally did anything to the hardware or BIOS.

Has anyone else experienced this? I'm pretty sure there is some tweak in Windows 10 that would fix this, but I haven't found it yet. Thanks for any suggestions you might be able to offer.

A:Power down button does not completely turn computer power off

I found the solution on another thread. If you have this problem try the following:
1. Log in as an administrator.
2. Right click the Menu button.
3. Left click -> Control Panel > Power Options > Choose what the power button does > Change settings that are currently unavailable
4. Uncheck the box next to Turn on fast startup (recommended)
5. Make sure Hibernate is unchecked.
6. Left click Save changes.
The next time you shut down the computer, it will be completely powered off. At least this worked on my machine.

I've tried 4 different power supplies, different processor, different BIOS batteries, different RAM, etc, but no matter how many times i try to turn it on it just wont turn on.

I do recall doing something innthe BIOS last night which seemed to start this dilemer. I went into power management and did something to the power switch option, then set everything back to default settings.

This is when things started to happen then my pc just wouldn't turn on at all.

It's a socket939 MSI CoreCell.

Could something i did in the BIOS really be causing this problem and is there a way to fix it?

Like i said there does seem to be power going to the motherboard but it simply wont turn on (i even tried different power switches just in [email protected]

Any help would be greatly appreciated. I just don't want to buy another 939 motherboard as most shops don't cell them any more and it means i'd have to buy a new processor too.
 

A:Computer wont turn on with power switch but there is power going through it?

If it is a BIOS setting, removing the CMOS battery for a few minutes should clear it. Since you've already changed the battery more than once, it would seem that is not the problem. Considering what you already tried, it might be the motherboard itself or possibly the graphics card but my money is on the motherboard. Just to be sure do you have another graphics card to test with?

Hi!
Recently, I upgraded my Laptop to Win 10. However, because a program doesn't work in Windows 10, I decided to go back to Windows 8.1. I did it through the "Settings" that you can find by clicking the "Start" button. After the computer restarts for Windows 8.1, it's all normal - Until after I enter in my password, the screen becomes black. The screen's not broken, because the mouse cursor is still there. I restarted it a coupon of times, took out the battery and everything, but it still won't work. Luckily, I still have most of stuff on my old HDD, so I can just use it. But I really want to use my SSD since it's much faster. I really hope someone can help me.
My laptop:
Sony Vaio S Series SVS151E2AP
Thanks.

We've had a recurrent problem with our Dell desktop (about four years old; Vista operating system) freezing up while videos are playing, usually on children's websites, for some reason (like Nick Jr. or PBSKids.org, for example). The video freezes and there is a loud buzzing sort of sound. Ctrl/Alt/Delete does nothing; we have to manually shut the computer off. The second to last time it happened, it would not turn back on. After considerable tinkering, it did finally come back on; weirdly after the ethernet was disconnected and reconnected. This time, it will NOT come back on. It is a doorstop. Just give it to me straight... Are we screwed?? lol...

System Protection is turned off. To turn it back on so you can use System Restore, see Turn System Restore on or off. 
 
I went to turn System Protection on, and this is what the screen looks like:

How exactly should I turn it on, to be safe? (I was recently infected by malwares.)
 
Also, I never upgraded to Win 7 or anything or using anything like dual-boot. It's a Dell desktop, if that matters.

As stated above, recently my laptop shut down and refuses to turn back on. More specifically, it shut down when I plugged a wired usb mouse into the usb port. I've tried turning it on with and without the mouse plugged in, to no avail. Any help would be greatly appreciated.
 

A:Laptop shut down and won't turn back on

What is the make and full model ID for that laptop ? Should be on a label underneath.

Try powering it up with just the battery (assuming it has some charge), charger alone and changer and battery together. Any change ?

I am running Win 8.1 on a Samsung tablet and use Windows Defender for protection. I own the tablet it is not part of any network.
I was searching the net and Defender reported malware. After a bit of a tussle the malware seemed to be removed but Defender was turned off, so I have no protection. I went into the Control Panel/Security Centre and it reported this and had a button at the end of the message for turning Defender back on. However the button did not work. It was visible but did not seem to be enabled. When I clicked on the defender app icon there was a message saying Defender was turned off at the Group Policy level and was controlled by the Administrator. As it is my own PC I assume I am the Administrator, but this did not seem to make any difference. I searched for Group Policy but nothing was found.
How can I turn Defender back on?

A:Cannot Turn Windows Defender back On

Hello Punchy, and welcome to Eight Forums.

Did you install a 3rd party AV program?

If so, they will often disable Windows Defender by default, and Windows Defender cannot be turned on until the 3rd party program is uninstalled.

Hello, I have a brand new HP Spectre which has only been used a few times. When I close the lid of the laptop, it goes into sleep mode, similarly when I press the power button once it sleeps. My problem is that when I open the lid and press a key, or open it and press the power button again, the keyboard lights up, the fan goes mental, but the screen never turns on. I've left it for upwards of an hour before and it doesn't turn on. When I put the laptop in sleep mode also, after about 5 minutes the fan goes mad. This is awful for when I'm trying to transport my laptop without having to turn it fully off. Should I take it back as it's still under warranty? Or how can I fix this?

My Spectre 360 made a fizzling sound then turned off. There was a slight odor from the vent. It will not turn on. It's completely dead and even the charge light does not come on when plugged in. I did a search to trouble shoot the problem and it seems that this is a very common issue with this particular laptop. I'm disappointed that HP hasn't reached out to owners with this model to rectify the problem. I have been a very loyal HP customer for many years and spend more on their computers because I know they will last. My previous HP cost about $2300 ( it's still kicking) and this one was around $1000. I'm 8 months out of warranty and frustrated that I spent the extra money only to have a really big expensive paperweight. if anyone has any input or solutions I would really appreciate it.

I've already consulted Samsung about this issue, and they want me to Refresh (windows 8) my laptop. I have important programs and I DON'T WANT TO DO THAT.

Started about half an hour ago, I plugged my laptop into the wired connection because it was downloading 6 GB. Plugging in a cord activates Airplane mode. In theory, once out of Airplane Mode, WiFi will turn back on. NORMALLY IT DOES, BUT NOW IT DOESN'T. THIS IS REALLY PISSING ME OFF.

PLEASE HELP ME. IT'S A BRAND NEW LAPTOP, NOT TO MENTION MY SECOND ONE OF IT.

A:WiFi turned off and won't turn back on.

Is this a second computer with the same issue?

I would suggest contacting Microsoft as it seems to be a software issue and not hardware. Especially if you can turn on the wireless manually.
