I have a Griffin PowerMate that I have had for about a year, all of a sudden the stupid thing just went nuts and ended up locking up my computer and causing all kinds of problems. I found this out after thinking that my os got hosed and did a restore from my backup drive and still was having problems. I ended up discounecting everthing and my machine ran fine with out a hiccup. I started plugging things back in and figured out the culpret was the PowerMate, I tried to download and install the most current driver with no avail. After further investigation of the PowerMate itself I was able to see what looks like scorching on the circutry inside the unit next to the LEDs (while looking through the bottom plastic). I figured that something went screwy internally so I called up Griffin Tech and to my suprise (sarcasim) they said it was out of warranty but they said that they have no similar problems and offered to send me a replacment free of charge if I gave them my credit card number so they could bill my 90% in order to due an advance replacement which would be refunded upon me sending the defective unit back. I have a replacment in the mail but has any one experienced any problems like this with there PowerMate?
