I'm not sure if it's the way I'm using my unit or if I am having a problem but I am getting some odities with battery usage. I find that there are times when I lose a lot of charge over night. For example, when I shut down for the night I was at 17 percent. In the morning I was at 3 percent. There are also times when I only lose 2 percent over night. What is running to use so much power? It doesn't make sense that a clock and calendar would require so much. I also find that the power level drops more rapidly once it hits 60 percent charged. I'm getting about 11 hours of actual usage although I managed about 8 once. Do I have a problem or is that normal? Other than that, I'm getting the hang of using my unit efficiently. I am having a bit of a problem with saving and retrieving items from and to the calculator but that's for another time. I'll read the help file again and I'll most likely get it! Have a nice day. Going to be about 60 and sunny! Anne West anne_k1stm@xxxxxxxxxxxxxx -- No virus found in this outgoing message. Checked by AVG Free Edition.
