I have a strange problem right now with my Precision M4500 laptop[8Gb Elpida 1333Mhz DDR3 RAM, 500Gb WD Black HD, Core firstname.lastname@example.orgGhz]. I had wiped the hard drive by overwriting it with ones and zeroes. I then re-installed Windows 7 Professional 64 bit on the hard drive. I proceeded to install the necessary drivers in the order that Dell recommended. And I updated the BIOS to A15, if I'm remembering right. Unfortunately the USB 2.0 ports on either side of the laptop do not work. I tried uninstalling each port in Device Manager and then reinstalling, with no luck. I tried updating the drivers on the USB hubs and that didn't work. I tried updating the chipset drivers, but that didn't help the USB 2.0 port connectivity issue. So now I"m a bit frustrated to say the least. Does any one have any additional suggestions for things to try?
Oh yeah, I also tried to cycle the ports by connecting it up to a PR03X docking station and then disconnecting it. That didn't work either.
A further note: The USB ports seem to have at least some amount of power running through them, as I can hook up my USB powered Thermaltake laptop cooler to it and it the fan and blue LED light come one once connected.
