USB Ports on laptop seem 90% dead
So I always seem to get good response on this site. Hopefully you guys can help me out again.
I bought a cheap powered USB hub off ebay. Connected to PC and when I plugged anything in was getting "malfunction" "unknown device" etc. So it was faulty. I then tried on the laptop to make sure. I then thought I'll try using some different leads to see if it was just the lead they sent me. When I connected an alternative power lead (I stupidly didnt check the v + A), it caused the laptop to switch off completely. I couldn't get the laptop back on for a sec. Was pretty sure the battery was at least half full. Eventually got it back on the the USB port I had the hub connected to wasn't working.
The other USB ports all seemed fine. I read about disconnecting everything taking the battery out and leaving it for 30mins may solve it. So i tried that but had no luck. So left it all unplugged disconnected over night.
Now today none of the uSB ports are working. I've tried plugging lots of devices in and am getting no response. Usually some of these devices would light up and stay lit while connected. When plugging in now to any USB port on the laptop the light might flicker on then off quickly. That's about it.
I've tried uninstalling USB related stuff in device manager, then restarting etc.
Any suggestions. Is my motherboard ****ed?
Unfortunately the laptop doesnt have any express/pcmcia card slots so thats not an option.
It's strange how at first it was only the port that I had the hub connected to that was faulty, now all of them are.
Any suggestions would be appreciated. Even comments on my stupidity of plugging the wrong power lead in to the HUB. Let me know what you think.
