• HP Envy 15 - q47002 i7: laptop overheating, does not recognize any USB. Even in the Bios.

  Hello

  I bought this product last year, so my warranty wore off.

  My laptop is overheating and it is very slow at this point (even videos are not working well). I tried to clean it up but it was without result.  I want the game and computationally intensive applications, but I'm afraid of the motherboard or hard drive failure.

  Now to the point. I can't install the new OS, any OS because this laptop doesn't have a DVD player and it doesn't recognize any usb 2.0 or 3.0.  I tried to change the options in the Bios and I tried to uninstall and install the drivers (they are up to date).

  What should I do? I can't install a new system because of this problem, and I can't use anything more demanding than youtube which is really annoying since this laptop has good specifications.

  I am currently running Windows 8.1 which I got when I made a purchase.

  I hope someone answers!

  Thank you.

  EDIT: In the Device Manager it says device not installed with yellow exclamation point. By Usb or ext hdd. And it will not find the device-specific drivers. As I never need them on another PC or laptop.

• Cannot stop a USB device due to some unknown program running.

  If I can't stop a device USB due to some unknown program running (like a virus), how can I find the program, so that I can stop it with the Task Manager?

  Hello

  The message (this device is currently in use. Close any programs or windows that might be using the device, and then try again) is usually the result of an application, file, open the document, audio or video, or any other application is being used (ranging from the USB key) when you try to remove it by clicking Remove the device safely in the notification area.

  The error can also be caused if your anti-virus is actively followed / analyze the USB drive. Normally, where the withdrawal of a USB flash drive, Windows must stop all operations of reading / writing on the disk so that it can be removed safely. If this is not the case, the flash player may be damaged or lost or corrupted data. However, if Windows determines that a file is in use, it can then provide a message that indicates the volume cannot be stopped now.

  So, before to eject or unplug a mass storage device, make sure that none of these activities are performed on the mass storage device before ejecting.

  A cut-off device

  Most USB devices can be removed and unplugged. When the fact of unplugging storage devices, such as USB flash drives, make sure that the computer has finished saving all the information on the device before removing it. If the device has an activity light, wait a few seconds after the light has finished flashing before unplugging.

  If you see the icon remove the device safely in the tray on the side right of the bar tasks, you can use it as an indication that devices have finished all operations in progress and are ready to be removed. Click the icon and you will see a list of devices. Click the device you want to remove. Windows will display a notification to tell you that it is safe to remove the device.

  I also suggest you make a system full scan just to be sure.

   http://www.Microsoft.com/security/scanner/en-us/default.aspx

  Note: The data files that are infected must be cleaned only by removing the file completely, which means that there is a risk of data loss.

• USB not recognized - even when there is no USB devices at all the

  For a few days now, I get the message

  "USB device not recognized: one of the USB devices attached to this computer is not working properly." The device has not been recognised "."

  He keeps popping up in my right corner below, every 5 seconds if I don't click it. When I click on the message, I get a list of devices (ports) are available. There is an "unknown device". Maybe it has something to do with the (biometric) finger scan? This has not worked very well lately...

  Even when there is no single USB device installed (normally, I have a mouse and a Targus laptop cooling mat installed as USB devices), it keeps popping up. I tried to remove the USB port from the list (or uninstall) in the remote control, but it seems that it keeps happening.

  I got it all of a sudden, I have nothing specific to has not logged any strange devices (except for a spotlight on exit external screen, but this has nothing to do with USB). I also hear the sound for the connection / disconnection USB devics randomly when I'm on my laptop.

  Someone has an idea?

  Thank you

• Satellite A100-991 - cannot boot from USB device

  My Satellite A100-991 (MS Windows XP MCE, SP3) does not start from a USB key or USB hard drive. The same USB devices are bootable if they are connected to a desktop computer or a laptop from other manufacturers. I put the USB as the first boot device and use an image "Bart PE" on my USB device.

  In fact, I have installed 2.10 Phoenix Bios version and I wonder if I could update the BIOS by using the 'sa105v21.exe' program and that this would resolve the startup problem.

  Hello

  Have you tested different USB keys? I think that your current USB key is not compatible
  Also test the USB to different USB ports. A port may be defective for the computer to start t with him.

  Theoretically, you can try upgrading the BIOS but don t forget s a bit more risky and it should be the last step.
  Prior to this, load default settings in the BIOS and check if you can boot from USB.
