My Toshiba NB 305-N310 netbook battery loses its charge after 1 week of non-use. Here is how I fixed this problem.
I’ve never had any previous portable computer exhibit this behavior. I’ve got an old Dell laptop that can sit for 6 month or more and maintain a charge. This little Toshiba netbook was losing charge completely after sitting unused for a week! I was about to return it to Costco when I found my solution!
The NB 305 Toshiba net book comes with a feature called USB Sleep & Charge. Apparently it allows you to charge devices from your netbook battery even while the computer is turned off. That sounded like a stupid feature to me… and one that I would never use. So I turned it off.
Immediately my net book started holding a charge! It can sit for weeks now (the longest it has gone unused so far) and maintain that same battery charge as when it was turned off. Somehow USB Sleep and Charge was draining the battery even though I wasn’t plugging anything in.
So disable USB Sleep & Charge and your NB305 battery should start working as expected.
