    Which non-Thinkpad laptops have battery charge thresholds function?

    Sorry, I don't know to ask this else where.

    Charge thresholds in Power manager is really useful, but I doubt that if other manufacturers provide this function in their products. What about HP? Dell? Sony?...

    Thanks

    i haven't seen it in HP, Dell or Sony laptops in the past.... i think IBM has a patent of some sort on this feature (i could be wrong).

    In some Dells they let you manually disable battery charging, but I definitely haven't seen anything on the lines of programmable thresholds. I don't think HP has either, but the last HP I owned was pretty old.

    I read that batteries last the longest when held at around 50% capacity... based on that information, I'm currently set to charge below 50% and stop at 75%, but I think I might go to 60% and 80%.

    oh man i cant imagine going back to a laptop that starts charging once you plug it in.
    definitely love that about my thinkpad and it would be a much missed feature if i switched to another brand.

    most of the laptops have smart charging circuit, which optimises for better battery longevity, but none of them allows you to physically set the battery charging threshold within min xx% or max xx%. From my personal experiences this is quite unique in thinkpads, not even ideapads have it.

    Ipeapads lack of many interesting functions in Thinkpads. They even can not use Power Manager, then I don't think they have battery charge thresholds

    ideapads are what we call the consumer range of laptop the design and development of which are mostly done outside of the Lenovo's own design centers (by the Original Design Manufacturer (ODM) - people whom not only contracted with the manufacturing, but also much of the design of the laptop). Thinkpads R&D are mostly done in-house, which makes them unique.

    This is how Lenovo keeps these consumer range laptops price low and spec high.

    You can choose to stop charging at 80% or 100%. Can't change the values, but handy none the less.

    Yeah, but was it IBM or Lenovo that added the charging thresholds to the Thinkpads? I don't recall my work issued T41 having it.

    On other news, it sounds like I'll get getting a T410 for my work computer early next year. Quite convenient, considering I already have a dock for it at home! Finally, going back to Thinkpads!! I was not impressed with the HP 6930p I had for a proof of concept project, and honestly my Dell D630 just blows chunks of udder crap.

    From what i recall reading, the technology was under development when IBM sold off their PC business to Lenovo. Lenovo simply released the software when people responsible for it finished developing it.

    Ahh so then my T41 wouldn't have had it..
    I miss that work laptop, the thing was built like a tank. Even more so than my T410 I have for personal use.

    T4x was a great laptop when the detaching GPU and southbridge problem was not affecting it. It was built like tank when the lid is closed, but when it is opened, i can feel the machine arching under its own weight when held in the corner with one hand.

    In that regard T60 was much better, truly a tank with that internal magnesium rollcage.

    Which laptops? All of them! Plug them in AC when you want to charge 'em (lower threshlod), then simply unplug when they're charged (upper threshlod)!!! :D

    Seriously, now, I believe no other stock laptops other than ThinkPads. Though I remember seeing somewhere some patch programming in linux for this; not sure, though.

    I believe the Dell E-series Latitudes have some sort of battery threshold feature, as do some Sony Vaios. Some consumer Dells also have a feature where you can choose to stop charging the battery, but you have to do that every time you plug in the laptop. None are as customizable as that of the Thinkpads' though.
