Battery Charging Problem

Hi All,
I have Linux Mint 12 installed on my Lenovo E430 laptop and I've relaized of late that even after an overnight charging my battery would only last for 1 hour. On looking into the battery information in system information while charging, I realized that the battery would charge only uptil 27.08% after which the "state" field in the system information would indicate charged and "load" field is set to 0mW. This is the first time I've encountered this problem over the past couple of months since I've installed linux Mint.

Any help would be appreciated.

1. Is it a new battery?
2. How long do you use this battery?
3. Do you work your laptop from ac-power while battery is charged and inserted into laptop?

Hi Sevs,
1. Yes, it's a new battery (I bought this laptop just 2 months back).
2. As mentioned in part 1, I've been using this battery for almost 2 months.
3. When the battery is fully charged, I unplug my laptop from the AC mains and use the battery powe, until the battery is kind of drained upon which I plug it to AC again. While I try to do this as much as possible, obviously, it's not always true.

In fact, as far as I remember, my battery would charge to 100 % and last for almost 5-6 hours until last week. I don't know what happened suddenly when I started observing this weird behavior.

If you bought the laptop new a couple of months back, it should still be in warranty which would entitle you to a new battery - surely!.

Now the difficult part, if you bought it with Windows installed, the supplier wouldn't be too keen on replacing it as they are likely to say you've invalidated he warranty by installing Mint.
I've never understood this as they're generally loath to sell you the laptop without an OS on it anyway! It's the hardware that's suspect, not the OS!

If it was bought in a store with a repair facility they might be able to let you leave it with them with a "replacement" battery fitted to prove if it's faulty or not. If it is, you should be able to have it replaced.

(I'll now wait quietly so that others can tell me how difficult/impossible this will be!! )

Play Bonny!

Hmm. Maybe there is something about power consuming setup. I heard about this about year ago, like "you need to setup something for your battery to not discharge too fast". Look for "laptop mode" or something similiar.
Here are somelinks:

The battery could have something in the contacts like dry salt or grease try cleaning the contacts very carefully .If you know someone with another way try their charger with your battery and their battery in your charger so you can eliminate either your battery or your charger as the problem.
