It appears that the keyboard charges fine, but no matter what I do with the mouse, it doesn't charge properly. It is almost as if it is going to sleep/standby and then not continuing to charge. It doesn't matter if the mouse is plugged into the keyboard or if it is plugged into the power adapter directly. For example, the mouse was plugged into charge (adapter) on Monday, 6/10, and I just took it off the charger today, 6/12 @ 2:06 PM EST. The mouse was at 33% charged, and was about 13% when I originally plugged it in. The lights on the mouse/keyboard come on when plugged into charge, but then they eventually go out. It is at that point that I thought it stopped charging. In order to get it fully charge, I have to leave it plugged in an make sure I "wake" it up every so often. Does anyone else have this problem?
