Ok so I got this Dell Inspiron 1721 a little while back and everything was running fine untill last night when my keyboard and mouse started flashing over and over, at first I thought maybe the plug wasnt in right and i unplugged it and plugged it back in, it worked for a little while then started doing it again, so i unplugged everything. I accidently left the mouse plugged in for a while and when I went to unplug it the plug was searing hot (was plugged in near the battery, whch could have been the reason for that), so now i think my laptop fryed my keyboard and mouse and it happened at the same time so I think all of my usbs are shot now. anyways my question is this, Is this a normal problem with the powered usb 2.0s? and since i think im going to have to send my dell in, do you think i stand a chance at getting my keyboard and mouse replaced by them or am I sol? together they cost me around $100 new.
