    Battery Meter conflict, windows7 v.s. manufacturer


    Hello, the windows provided battery meter, and my Linux counterpart battery meters read the same value, I've been having power failures recently, basically capacity dropping from 60% to 30% over matter of a few seconds.

    I am currently running the manufacturer's battery reset software. However, I'm curious, which one do I trust?

    When working at HP I found the battery meter it had, reliable.

    However, in your case, as Linux also disagrees, why not let it run to 0% and see for yourself? (and then tell us, please)

    BTW: What type of laptop is it? Have you researched for any credibility issues on that particular application?

    It is Lenovo T430. From my findings, the laptop and software should be perfectly fine. I am pointing at ACPI chip in battery failing. It was uncharacteristically cheap battery I replaced the stock with. I had the new battery exactly for 14 months now.

    I noticed the terrible battery calibration, or some sort of issue when I was running a short code I wrote which I ironically named "batterykiller", as I expected it to be very power demanding.

    The battery meter from Linux and windows are both unreliable to true capacity also. The charging gets "stuck" at 77% but it says the battery is still charging, but no change. Also, at 30% the computer crashes due to low battery.

    I've been checking things via software.

    Manufactured for 75 Wh, available 64Wh(aging probably), but the battery refuses to charge after 45Wh. So, pretty much charges up what 6 cell battery would hold. I think 3/9 cells are dead. The battery meter on an older stock battery seems to work properly. I think both the 3 cells died, and the internal circuit inside is failing to recognize dead cells.

    I ordered a new battery, and I am going to dispose of the 1/3 dead battery. I have dealt with Li-Pos burn up on me before, I'm not as familiar with Li-Ion, but I certainly do not wish to take chances.

    For the time being, I am using the stock 6 cell battery with 75% capacity left, and I gave the dying 9 cell battery to my server laptop(which is an identical which remains powered at all times at home, acting as a pseudo-server).

    I'm curious, are there any safety software that recognizes hardware failure in batteries?

    Not safety software that I know of - I think some of the tray type utilities have battery meters and maybe alarms that can be set - not sure if this would help

    There are also battery testers and similar that may give you more information or at least an ongoing data record for comparison - one is shown here ... Determining the maximum capacity of your laptop battery.
