I have a Logitech cooling pad for my Dell 17" Studio laptop with 4 GB RAM and Vista Home Premium. It mysteriously stopped working. When I plug the cooling pad in other laptops, it works fine. I have...


Seems that your laptop's USB ports are not providing enough power to the cooling pad. This could be due to you connecting too many USB peripherals to your laptop. Test if you can get the cooling pad to work by disconnecting all other USB devices.
As a permanent fix, you can buy an active USB hub (one powered by external power source) & connect your cooling pad to it.

My mouse doesnt get detected on my system. please help


Instructions
  1. 1

    Turn off your computer.

  2. 2

    Unplug the power supply, remove your laptop batter, and wait at least 30 minutes before returning the battery and power chord to the laptop. As explained by Trouble Fixers, a cache of data from your USB device is stored on the motherboard. This cache is not completely erased until the motherboard fully discharges following power-down. Once the cache is cleared, most USB errors will be fixed.

  3. 3

    Turn on your laptop computer.

  4. 4

    Try to use the malfunctioning USB port. In most cases, simply turning off and unplugging the laptop will help remedy the problem. If a problem persists, continue with Step 5.

  5. 5

    Click on the "Start Menu."

  6. 6

    Click to open the "Control Panel."

  7. 7

    Click on "System and Maintenance."

  8. 8

    Click on the "Device Manager." A new window will open that lists all hardware and external devices currently installed on your laptop computer.

  9. 9

    Scroll the list until you notice the heading "USB Root Hub." Click on this option.

  10. 10

    Select the USB port that reads "Unknown Device." All other, functioning USB ports should say "unused port" or list a specific external USB device.

  11. 11

    Right-click on the Unknown Device port and then select "Update Driver." According to the tech-help website, Amit Bhawani, this will trigger an automatic update of the USB drivers. If no new drivers are found, the old driver will also refresh and repair. In many cases, a malfunctioning port is simply caused by outdated driver software. With the latest drivers, your port can be used with current USB devices without any problems. If problems do reoccur, then the port may be physically damaged and you'll need to take the laptop computer to a computer repair technician to get a new USB port installed

Dead USB Ports...


First go into Device manager and see if there is a Yellow! or a Red (x) next to any of the USB ports. If so right click and there will be a tab with solutions. If that doesn't get you anywhere go into BIOS and search for all of the USB ports. You should be able to add or turn onto Automatic to get them going. USB is simply a port, so some kind of the way the ports either got shut off or they are blocked.

USB Port has failed; 4E00:032B


Electrical surge on hub port. Either a device attached to the port, or the port itself, has drawn more current than allowed, and the hub turned off the port. The port will not function correctly until you reset it. If the device is the cause, it must be detached before resetting the port. To reset the port, disconnect the device, and then click Reset in the dialog box. If the port is the cause, close the dialog box, and do the following to re-enable the port:
Disconnect the hub.
Re-attach the hub.
If it is the root hub, unplug all attached USB devices from the computer, and (if they have power supplies) unplug them from the electric supply. After a few moments, reconnect the devices. The computer can be restarted at any time.-->
