laptop keeps turning off even with 70 % of battery,

[piyush]

the laptop turns off automatically without any warning. When again switched on, it shows the right amount of power reamining but again starts draining quickly and turns off in about 10 mins. Again when switched on it has the right amnt of battery left.
The battery is fine as it works well with windows and gives around 2.5 hrs .I am running 13.10, upgraded fron 12.10.

indicator-power only shows the power remaining; the actual shutdown is done by gnome-settings-daemon's power-manager plugin. However, it's doing it in response to what it's told the power charge is by upower, so I suspect that's going to be a more useful place to report this issue if it is software-related.

To be clear, you're getting this without any "laptop battery critically low" type messages?

Could you attach the output of "upower --dump" from before the laptop shuts down?
