False "Low Battery Alarm" with after-market battery - Dell Studio

Hello,

Sorry for being away from posting on the forum since a long time, though I have been visiting the forum lot many times, without logging in - mainly through Google search. That shows how effective the website really is.

Since some time a very persistent error has been bothering me and I thought it best to come here and post the issue.

After my original battery for my Dell Studio 1555 32-bit computer died, I replaced batteries thrice, one after another (the computer is five years old).
The three replacement batteries were:
1. Dell - exact replacement 56 Wh
2. LB1 - matching specs but 48 Wh
3. Dell - exact replacement 56 Wh

Since the second replacement battery, the Low Battery Alarm has been disturbing me each time that:
1. The computer is restarted with the main power disconnected.
2. The main power jack is removed after a 100% charge.
3. The main power jack is removed anytime.

Since in the first place I never set this alarm manually, I am assuming there could either be a Dell specific registry issue with after-market batteries, though I don't understand why. Either way the irritant must go.

I checked Advanced Power Options under Power Scheme but found nothing that would give me a hint of what's wrong.

The alarm screenshot is attached.

Any help would be welcome.

Rule out the OS and Drivers by downloading a Linux LiveCD and booting from that See if you get the same errors/alarms/warnings.
If you do it could be a faulty charging circuit in your laptop. Check with Dell and see if they have a battery calibration tool. Sometimes completely running the battery flat a couple of times does a "reset" kind of thing.
Sorry I can't think of anything else just now.
