    Hey guys!

    So I just bought a SL500, and I tried to change the batt threshold but I couldn't find it in battery info under power manager. I searched on google and looks like SL500's batt info window might look different from the other thinkpads. Does anybody know where I can change the threshold on SL500?

    Thank you very much in advance!


    Here's how my batt info page looks like (borrowed a pic)

    The SL series may not have this feature (it is a cost reduced model).

    See attached picture for where the "Battery Maintenance" icon would be.

    It appears the SL series doesn't have that feature. That is rather unfortunate imo. Another reason a SL shouldn't have a Thinkpad logo...

    This is a little off topic but I was wondering what exactly the battery threshold feature does? I know it sets some sort of limit to how much is charged or when it starts to charge? But what are the pros and cons? Why wouldn't I want my battery charged all the way to 100%?

    Read the battery guide and go to BatteryUniversity.com for full details.

    However, the short version is that unnecessary cycles (charging and discharging the battery) as well as keeping a battery at 100% (especially while warm) is very bad for long term batter health. Charge thresholds provide a convenient way to minimize both of these problems.

    Did Power Manager 3.20 or above add back/enable changing battery thresholds for SL series users? I asked at http://forum.notebookreview.com/6195005-post52.html but never got a reply.

    I might be in the market for one... I'm looking for the cheapest Lenovo non-netbook I can find which has the power manager only to VPN into work occasionally. It seems only Thinkpads even give you ability to set the thresholds.
