Hi everyone, I have reviewed this thread over and over for the last couple months while I tried to tackle the problem on my HP DV4170us laptop. I wanted to share my experiences so hopefully they can help some of you. For me, this was an intermittent problem until one day it was permanent. The USB ports were working fine, then they started acting up, and finally one day, just quit working all together. I tried just about everything imaginable in terms of a SW fix from virus scans to many things posted on this forum. I never performed an OS restore because I did not believe that was the problem at all. My solution: I purchased a new motherboard on eBay for $75 and swapped mine out. This completely fixed my problem! I am not sure at this time of HOW the USB ports on the motherboard went bad. Connected to my laptop are two external hard drives, optical mouse, and an M-audio FastTrack recording interface. It may have had something to do with the M-audio device, but I am not certain. I never liked the fact that the unit was USB powered. I have since purchased a powered USB hub so that it will have a separate power supply. I am wondering, how many of you with the USB problem have experienced other problems as well. I am particularly interested in the people who have had luck simply taking out the battery for 30 mins. For myself, I had also noticed intermittent keyboard functionality, problems shutting down the computer, and battery charging. Lastly, when my computer first boots, the screen had a red/pink tint to it until the windows XP logo appears and then the colors were normal. Many of these problems lead me to think it is a power issue. Has anyone simply tried replacing the AC adapter and/or battery? Even though my computer is working again, my battery still doesn't charge. I would like to determine if this issue is related or not. Best of luck to you all.
