Win 7 (64) "sleep" and "hibernate": power supply for USB devices

Hello: Just ordered a new PC with Win 7 Ultimate (64) and I need advice on creating a power plan. I learned the hard way with Vista Ultimate (32) that "sleep" and "hibernate" cuts the power of USB, such as UPS devices with battery backup. It was a bad function, since my UPS runs the software that automatically stops the system if necessary. However, when the Vista computer went to 'sleep', the connection to the ASI has been cut, while the UPS is no longer communicates with the central unit. Therefore, if stopped and directed were needed when the system is idle / "asleep", UPS might not make it. The only solution I could find was to create a custom power plan that stops the CPU (and that only updates the display on screensaver for X minutes and then turns off the screen). Obviously a question of wear for the system, being never in mode 'sleep'. Windows 7 behaves similarly, depriving USB power in "sleep" or "hibernate"? Will I need to apply the same workaround? Please notify. Thank you! daledoc1

Right click on the USB device device manager concerned and select properties then power management and clear the option to Turn off energy-saving and activate the option to wake up from its sleep.

  • Sleep and Hibernate works not properly

    Hello
    I have a laptop HP running Win7 64 bit which has developed a problem when you use power-saving features and ensures extended. I rarely stop or restart the system and very rarely use Hibernate, opting instead for simply use sleep function when I close the lid. Stop and restart both to perform as expected, but whenever I try to use the sleep function, either by closing the lid or via the options on the start menu, simply, the screen goes black and the laptop runs - the fan is on and the hard drive light flashes sometimes. I waited for about ten minutes, but nothing changes. Then, when I lift the lid to wake the system, nothing happens and I have to do a closed hard. The same thing happens with the Hibernate.

    I used the system restore already to try to resolve, by choosing a restore point, a few days before the recent updates or system changes, I did but the problem remains.

    I also changed the settings in the power settings to try to solve the problem, but once again failed to do.

    I turned it off Hibernation using start, run, powercfg-h off but once again, this has not fixed the problem. >

    Any advice greatly appreciated.

  • Questions about the replacement of a power supply for a P7-1235

    I decided to do an update on my Pavilion P7-1235. I put in a graphics card and put in power level. After doing some research on this forum and others I know well enough that I need. The only question I have is about the food. I don't know what the original power supply. There is a vent on the side where it however. So I guess that there is a fan on this side of the power supply. This eating plan I get:

    http://www.Newegg.com/product/product.aspx?item=N82E16817139050 & TPK = % 20500% 20% 20modular %2 watt Corsair...

    I noticed that the fan is on top? Now there is no high ventilation in my P7-1235, I worry for nothing? I think that all the supplys to look the same. What is the top of the fan page for? Or can anyone suggest a replacement perfect for my exact Pavilion model?

    Sorry if the questions are stupid, but I'm still learning and want to do what I can myself!

    Hello

    Yes, you can use the power supply the same way. The image is in a vertical position for the convience of the buyer. I have the same with number of power supplies and it was fine. You can check the following links people have set up exact POWER supply in different ways.

    http://pcpartpicker.com/builds/by_part/Corsair-power-supply-cx500m

    However, please be aware of your power supply size and your case. If you have all materials/components in stock for your computer, then it is what it is;

    ATX case:

    : Height 39.4 (15.55 inches)

    Width: 17.5 cm (6.89 in)

    Depth: 40.9 cm (16,14 inches)

    PSU stock:

    (5.9 x 5.5 x 3.4 inches)

    And the power supply you want;

    Corsair size;

    "5.9"x 3.4"x 6.3"

    As you can see the length of the Corsair is considerably larger than your stock of power supply. This could hampor of air or could even make it so the holes of the PSU and the case does not match. However, this is usually not what worry. The height and width that should be worried because the length rarely causes problems, I wanted to just make sure that you knew in advance.

    Take advantage of your power supply; Corsair is a great brand.

  • Power supply for use in the UNITED Arab Emirates

    Hello

    I just bought a Time Capsule of the airport and an Apple TV (4th gen).  I'm moving to Dubai for work and I intend to take with me.  I can't find out how to replace the power supply for use in Dubai (plug type G).

    • Can I just buy a travel voltage converter?
    • What is the frequency difference (US is 60 Hz and UNITED Arab Emirates is of 50 Hz)?
    • Could I just buy a 'EnergyPal travel Charging Station ETCS04' and connect directly?

    Thanks for any help!

    The airport Time Capsule and the Apple TV work on 100-240 Volts and 50/60 Hz automatically, so they'll work pretty much anywhere in the world if you have the map of the right ankle.  A voltage converter is NOT necessary.

    You can buy the cards you need to any store from the airport, luggage, in Dubai store, etc., most of the hotels the.  If I remember correctly, Dubai uses the same type of plug that she used in the United Kingdom, as well as should work as well.

    I do not think that the higher 5 GHz channels are permitted in Dubai, so be sure to put the time Capsule to use a lower numbered GHz 5 channel... 36, 40, 44 or 48.

    Hello

    I have a HP p6210y (http://support.hp.com/us-en/document/c01859864) and I need to upgrade the power supply for the Radeon HD 4890 I have now. I am reviewing the PSU below. However, the dimensions are actually smaller than my current diet. Who's going because of my problems in terms of ride it properly in the case?

    http://www.Newegg.com/product/product.aspx?item=N82E16817338038

    If this will cause problems, can anyone suggest a power supply (it's the exact size as my current) which would be suitable for my graphics card. I need "500W with two connectors to power 75W 6-pin PCI Express.

    Thank you!

    I believe that the PSU is designed for a different style of the case. Discover the Corsair CX500, or CX600 power supplies. They are highly recommended and are favorite forum. In addition, they are only slightly larger than the stock power supply HP and are known to adapt.

  • HP Elite 1090-T H8: seeking your suggestions for upgrading the power supply for a new video card

    I have a HP EliteH8-1090 t who is about a year, but with an AMD Radeon HD 6570 low power graphics card and a 450W power supply. I want to upgrade the 650W power to support the installation of a replacement graphics card.

    I tried to replace the HP 450W with Corsair TX650 and Corsair TX850 food. The system appears to power (DVD drawer opens and closes, the hard disks spin, fans run) with either a Corsair, he's stuck at this point. My system is unable to enter start mode when either power supply is installed - it seems stuck in a mode of seed, and the monitor still asleep.

    Can someone please advise on a compatible power supply for HP system? I'm puzzled by why a simple exchange of a power supply does not work. Just like a record, the system has a card mother Pegatron IPMTB-K (Truckee).

    Thank you!

    No problem. I wish you good luck with it. On a positive note the HX650 is a much better than the TX650 ILA unit internal quality and what I like is the best it's quite fan fan much quieter than the TX650 while helping your organization of cable being modular and help keep temperatures cooler in your computer case.

  • Power supply causing USB problems.

    I recently bought a HP p6267c at Costco. It is a system of Q8300 with 8 GB of RAM and it works quiet well. As the graphics card on this subject is not as good as my 9600GT, I decided to give it a shot. Only problem is that the power supply on the HP does not have the PCI-E power connection. I put in my diet from my old computer and the computer starts well, just all USB ports do not have the connections of the mouse or the keyboard. I plugged in my iPod and he acknowledged and grew. I wonder what could cause my power supply for connecting USB not notice just the keyboard and mouse.

    Well, it provides enough power for the USB on my old system. Also, I put the 4350 in the system and does not require the PCI-e power, and it still does not detect the keyboard or the mouse. I don't know exactly what is the cause, but the 5V shall not work just somehow on the new computer. The Board just freaked out on me too, so I think return this machine and starting from scratch. Thank you for the help guys, but I just think I got bad luck on this one.
