Battery empty after long inactivity

Question

Dear fellow users, I have observed strange battery behavior with my Twist. I do not mean anything related to the battery life when computer is on, but when I shut the computer down. When I leave it off couple of days and then restart it, the battery capacity (how much it is charged) seems be at the same level, when I powered the computer off. But it happened to me twice already that I shut down the computer (no sleep, there would be a blinking light visible) and did not use it for several weeks. When I restarted Twist after several weeks of being off, the battery was completely empty (e.g., at 4% or 5% when it was originally at 50% or 99%). As the battery behaves normally when computer is running, I am wondering what a cause could be? Is there some software setting influencing power states (e.g., sleep / deep sleep / complete shut down)? Any other ideas? Thank you. Best, Pavel

UPDATE (new info): it happened again, but now more specifically. 1) Two weeks ago, I used twist on battery, turned it off with 50% battery remaining, and was not able to use it for more than a week (busy at work) --> battery level almost did not change after this, BUT 2) Two days ago, I used Twist connected to the power net (electricity), the battery was full at the end, then I turned Twist off ... only to find out that after 2 days (!) of no use the capacity of the battery was at 70% level. Any idea what is going on? I do not think there is a problem with the battery itself, but Twist "does something" sometimes...
