Hello, I have an Acer Aspire One 110-Ab (Ubuntu 10 installed now), with a very big problem for months I bought a 7 hours battery and months later the problem appeared (I don know if this battery was the origin of it): If I use it with any of the 2 batteries the screen goes to black a few minutes after using it. If there is a secondary screen it loses connection. It's still on, but you can't do anything. The batteries are ok, fully charged, so I think the problem is in my netbook (something in the battery power system doesn't work). The only solution is to switch it off. Any idea? Sorry for my English, it's not very good. Thanks!
