Ubuntu killed 2 batteries (thinkpad x41t)

[wbonx]

Hi,
everybody knows that linux have big problems managing power autonomy of laptops.
But what everybody doesn't know is that the modules that have to manage the battery charging program and powersupply are so bad coded that often battery life is reduced consistently after using a linux system (ubuntu) for just 2-3 month.
Personally i burned 1 battery using it just 3 month with ubuntu when under windows it gives about 5 hours of power (now 50 minutes).
Then I bought a new one, changed the modules, used modules built for my thinkpad x41t and the new battery lost 50% of his life in about 2 month.

How is it possible? I lost something like 200euros cause the 2 batteries where original IBM replacement.

Where I have to submit the bug? Is a kernel bug or the problem is that ubuntu is using not well written modules? or what else?

Thank you.

Linux really isn't bad at handling laptop batteries. It's just a matter of having the right drivers and keeping the battery from getting damaged by heat. The best thing you can do is remove the battery when you aren't running on it or charging it. More info here: http://www.thinkwiki.org/wiki/Mainte...tery_treatment.

No. It really isn't about heat and drivers. There is something very wrong with the way Ubuntu handles laptops. I have also had a few laptops that had got their batteries completely killed after installing Ubuntu.

See https://bugs.launchpad.net/ubuntu/+s...er/+bug/481576 , essential part is "Apparently, draining a Li-on battery completely kills the battery (mine only has 9.8% of it's original capacity).".

Edit: Mine went from 2.5hr to barely 2min after two hibernations. Luckily my laptop is used constantly from AC anyway. Else I might be a bit angry...

I too did notice this "sucking of power" from my netbook, it's supposed to have 6-hour battery life....turned out i needed to disable the wireless to get the most out of it.

It is not about how much power it sucks. It's about how much it drains your batteries total capacity.

Edit: it still has status of "Low" on the bugtracker.

Quoting Samuel Kogler:
May I ask why the priority of this bug is LOW? This can damage hardware seriously, and open work is just gone...

My bad..... either way it still drained my batteries lol

Now I am really scared to use Ubuntu ... I was happy when i first installed and started using it. Now if it spoils the hardware, then its better for me to use Windows...

Nooooo!!!!! Please don't lose yourself to windows!!! (That said I do run Windows on my second laptop for the same kinda reasons) I should've said this earlier: the battery life improved after a kernel update so all is good now. I get 3-4 hours when using WLAN and 6 hours without using WLAN. It used to be 1 hour with WLAN.

If the laptop doesn't shut down before the battery is totally drained (I always thought the hardware cut out before that happened), then could well lose some capacity; reconditioning methods may fix it. I've never seen this happen on any of our laptops, so it must be uncommon at the least.

Could you explain:
