UPDATE: For those having issues with the unit being sick at .79Ghz, the problem is the power adapter. These units are being shipped with 90w adapters, which are simply NOT SUFFICIENT. This unit needs at least a 180W adapter to function properly.Unit was not booting when it arrived. Rather than deal with trying to troubleshoot it, I tried returning it for a replacement. It already took a week to arrive and then I would have to wait until the sellers receives the defective unit before they would even send it the replacement. So I opted to troubleshoot and fix it myself.
