Ubuntu 10.04 new battery calibration procedure ...

Asked by Dave Cooper

    I posted a similar query to the Ubuntuforums under Dell Ubuntu Support and no one has responded, so I am posting here. I hope that is OK ...

    I bought a new battery for my Dell Latitude 2100 netbook running 10.04. It is the first new battery I have had to buy for this device.

    Before I install it, I thought I would check about the procedure to calibrate a new battery for this Ubuntu machine. (On my Windows XP netbook, after I install a new battery, there is a specific procedure and recommended iterances of that procedure before normal usage can resume). I know how to do that in Windows XP.

    Is there something similar with Ubuntu 10.04? The battery is:
    Dell Li-ion, Type F079N 11.1V 28Wh capacity

Thanks ...

That no one responds may be because not so many buy a new battery, they rather buy a new laptop.
Also uncertain what you mean by calibrating.
A common procedure is to load and unload it completely.
Ubuntu 12.04 comes with some standard power utilities e.g. power statistics to review load cycles and of course modules of the kernel itself. Another tool would be powertop.

Thank you for responding. I am not sure about providing links here, calibration is best explained in the following web page for Windows devices. When you buy a new battery for a Windows device it is recommended that you calibrate the new battery:

For Linux devices, the only discussion I have found is the following:

I am using Ubuntu 10.04 LTS.

I will leave this question up there for a few more days to see what comes up.

Dave, thank you for the links.
Well the second one basically says the same as I did, if that calls calibrating then fine with me.
I do exactly this with my diving torch and laptop.
>> A common procedure is to load and unload it completely.

------ Quote of second link:
Recharge you battery to full, 100% if possible.
1. Right-click on the battery icon on tray and choose settings
2. Find the battery settings and set everything to "Never", ie. the system will not shutdown when battery is low
3. Let the machine run until battery is dry and machine switches off by itself. (not to suspend or shutdown, mind you)
4. You might want to take the battery out and then back in, no idea if this helps, but shouldn't hurt either.
5. Plug-in the AC-cable and let the battery recharge to full
------ End of Qoute.

And yes of course Ubuntu contents battery settings and tools as mentioned.
Insert a 12.04 live medium and test it yourself.

It may sound stereotyped but I'll repeat it anyway - Linux is *not* Windows.

Xianggang ...

Thanks for responding. I resolved the issue shortly after initially posting the query. The calibration technique I used is essentially the same as on other OS's.

Groetjes ...
