I just bought my gTablet a couple weeks ago on Woot.com during their woot-off and have only had it in my hands for 5 days (long enough to root it with Vegan 5.1 though)... and the power adapter seems to have failed. When it did work, it made a buzzing/hissing sound. Now it's silent. I'm currently waiting on a response from Viewsonic support on the problem, but I'm curious. This has a 12v 2A adapter. I believe my Asus Netbook has a 12v 3A adapter, but it's not with me at the moment, so I'm not 100% sure of the plug fit. Has anyone else had issues with the power adapter, and if so, have you found any other adapter to be a good (enough) fit for the gTablet?
