    This happens on my daughter-in-law's computer. When she attaches a USB device it powers off her computer. Just inserting the connector completely shuts down the computer. What could be causing this? This is a Dell Inspiron E1505 laptop running XP Home

    It is any USB device but only in the top port on the side of the computer. The ones in back don't cause the problem and I can't get the plug into the bottom one on the side.

    This makes me think that there is a hardware fault probably Mother board related however, owing to the fact that the USB ports have a power supply it could be dirt of dust creating a short and the PC/Motherboard shutting down to protect it's self, have you tried giving the port a good blow out with compressed air? and does it still shut the PC down with just a USB cable is plugged in with no device connected

    I will try the blow out. It shut down when I plugged in a USB flash drive. I don't know if that is considered a device connected. I'll have her try just plugging in a cable. I suspect it is the port that is shorting out.

    I would say that the ports are not connected to the MOBO properly, who built the PC?
    if the back ones are working and the front ones are not then, its not likely to be anything else

    If you have a few USB devices attached at the same time such as keyboard, mouse, printer and then plug another device such as a flash stick then this can be enough to overload the rail that the PSU uses for USBs

    Dell built this computer. The only device plugged in is the printer. I am leaning towards two separate issues.One is the USB port which I think might be faulty since she told me it might have gotten dropped. I can't get a plug into the bottom port on the side. The ports in the back seem to work. I was able to get a different printer to work so I think the issue she is having with her printer is related to the printer, not the USB port.

    It sounds as if you have a faulty USB port. (Possibly damaged when dropped) It's best not to use it at all. (Hopefully not a prelude to motherboard failure)


    All Dell computers ship with a utility partition on the hard drive that contains the Dell Diagnostic Utility: You can test the hardware
    using this. Use the symptom tree to test for USB connectivity. (Otherwise the test will run for all hardware)

    Restart the computer.

    As the computer boots, press <F12> when the Dell Splash Screen appears.

    When the Boot menu appears, highlight the Boot to Utility Partition option, or the Diagnostics option and then press <Enter> to start the 32-bit Dell Diagnostics.

    Press the <Tab> key to highlight Test System Press <Enter> to continue to 32-bit Diagnostics.

    Express Test will run a quick test of devices in the system. (Takes 10-20 minutes.)

    Extended Test performs a thorough check of devices in the system. (Takes an hour or more.)

    Custom Test used to test a specific device or customize the tests to be run. Exit to MS-DOS will exit the diagnostics to a command prompt.

    Symptom Tree. This option lists the most common symptoms and allows you to select tests based on those symptoms

    I will try the diagnostics the next time I am at her house. Thanks for the advice
