Battery problem on Ubuntu 12.04

[John_Gone]

Hello,

Since a while, I noticed my laptop has a kind of problem with the battery consumption.
When the battery is fully charged, the laptop goes on normally and then, after a certain time (depending on what I'm running, a video, a game, etc...), when the battery notifier arrives approximately to 1:20 of energy left, my computer goes immediately off without any warning. It doesn't display any logout logo at all, it just turns black, and I have to plug it with the charger or it won't reboot correctly.

How is this possible ? Is there a problem with the battery itself or can I fix this directly with some command ?

Also, I'm a complete newbie so if I forgot to mention something important, please tell me.

Thanks in advance!

I had the same trouble with my phone - it would shut down at 25%. The "Reset battery estimates" function didn't help. I bought a new battery and now the phone battery lasts until 1%.

So... I should change my laptop battery ?

Sounds like your battery is toast.

Usually through the cycles of charge and discharge, battery time decreases. You use to get 2 hours on battery, now you only get 1 hour, and so on.

If your battery is showing a set time left before charge - but then suddenly no power and system goes off - probably damaged cells in the battery.

Sorry to say, probably time for a new battery - or run plugged in

Well, I think I'm going to buy a new battery then!

Thank you all for replying!
