I accidently left my whispernet on and it drained my battery completely. I recharged it with no problem, but since then it takes about 30-35 seconds to wake up. Also if I try to turn the pages it sometimes takes about 7-10 seconds to turn. The previous page is jumping back several pages. After it has been on for a while it seems to work fine. I tried a reset but this did not correct the problem. Has anyone else seen this problem or have any suggestions?
