Battery Capacity

[spork985]

This is the third battery I've tried, it lasts about 50 minutes in my hp dv9000t notebook.

Now I just installed Ubuntu and I see this

How can I make it charge to the full capacity???

Thanks!!

You can't. Everytime you charge an Lithium ion battery it loses a tiny bit of capacity - Over time the battery will become less and less efficient in storing energy. I'm guessing you've had the battery a while?

You're options are to either buy a new battery, keep the laptop plugged in, or buy a new laptop (obviously with a new battery).

Did you buy it used? Old batteries lose capacity over time - all you can do is get a new battery. Of course, if that's a new battery, something is seriously wrong.

It's brand new! I just got it and had two before it that had the same problem.

Where can I get one of these Li-Ion calibration programs I keep reading about? There is none in my bios.

I sounds like a hardware fault else where. Perhaps a dodgy power supply connection isn't providing sufficient juice to charge the battery? I don't know, but it is VERY unlikely to receive 3 defective batteries - unless it was a bad batch.

By power supply, are you referring to the external transformer or something inside the laptop itself?

Either. It is hard to say.

Try taking out the battery, plugging the laptop in to the mains and turning it on. Does it work?

Yup, works fine. I don't like using it this way though because the battery acts as an UPS.
