Comment 3 for bug 354584

I'm experiecing a similar behavior.
When I had intrepid my battery lasted, at least, 3 to four hours (Dell Vostro 1000, 9 cell battery), with Jaunty I'm experiencing the same 10-20 minutos battery life as Joe.

I've tried running powertop and using it recomendations but that didn't seen to help.
Dunno if this is relavant, but it says that it cannot get a estimated baterry live from ACPI.

I'll try loading a 2.6.27 or a 2.6.29 kernel to see what it gives me.

Any aditional info I'll be glad to provide!
