    It could potentially be a faulty battery. But I have to ask, which operating system are you using? Windows 7 without the appropriate BIOS upgrade doesn't play well with batteries on the D250 (speaking from experience). Also, have you tried updating the BIOS to the latest spec's?

    I'm also having this problem. My battery does not charge more completely. I'm using ubuntu 9.10. Until yesterday my battery charges 100%, now no longer loads. Francees you could fix?

    I have had this exact problem with two separate batteries. I managed to fix one of them by doing a couple of cycles of fully discharging the battery and then charging it for 8 hrs.

    If you try it, you need to disable any power monitoring that will force the system to shut down or hibernate at a specified battery level as you need to discharge the battery completely each time.

    Laptops have smart batteries that follow the spec http://sbs-forum.org/. The chip inside the battery-pack does all the things and communicates via I2C (or more preceise SMBus) to the laptop. The smart battery might require a capacity re-learn cycle (see sbs spec) that is typically a full-charge, fulldischarge,
    and repeated to full-charge of the battery pack to preceisly estimate the batteries estimates.
