Losing Connection With Display When Booting Whith Usb Device

by NMNuZ / May 16, 2013 8:42 PM PDT


I'm having a strange problem with a user at our company. When she boots, while a usb device (doesn't matter which one) it boots well, but after you get the screen 'Starting Windows' the screen gots disconnected and it is like when you put on the screen before booting the pc. The button of the screen is flashing.Anyone has an idea?

Not that uncommon

That's not that uncommon really, and one of the basic troubleshooting steps of any boot related issue is to disconnect all non-essential devices from the computer.

If swapping the unit out for another one isn't an option, then you're probably better off explaining to the user she'll just have to plug in her flash drives and whatever else AFTER the computer finishes booting. If I had to guess as to why this is, I'd say that she probably has a number of USB devices, more than one are of suspect repair and/or origin and somewhere along the line that device (or devices) damaged the USB controller on the motherboard. Assuming my hypothesis is correct, it probably is in the very early stages of failure, and you should expect it to fail outright at pretty much any time, though it may well continue on as it is now for years.

You can also try reloading the OS, hoping you get lucky and it solves the issue, but I doubt it will.

Happened to me.

This is a sad story of HP failing me for the last time as a new HP laptop that would not boot with certain USB devices plugged in. The BIOS was set to not boot from USB yet the BIOS would hang until the device was unplugged.

HP was never able to correct that issue and in fact, destroyed the laptop in their repair center. It was my last HP.
