Found this cute little guy. Battery bms seems to either be dead or cell voltage too low. Has anyone in the Linux community revived a BMS before or recharged from zero?

    Did you Hackintoshed it? Because it looks like it’s booting MacOS.

    I love netbooks. I regret selling mine after Archlinux went 64bit only. It was beautiful (all pearly white) and small and the keyboard was perfectly usable even for my fat fingers.

    What’s that apple doing there? That’s vile.

    If you think the battery isn’t just dead dead dead and resetting the on-battery chip somehow can help, I’d like to know how, too.

    I just remembered something - often (and more likely the older the device is) - the battery consists of an array of standard cells which can be bought separately. So if you feel adventurous you can pry the battery open, unsolder the cells, test each one separately - chances are there’s just one that’s completely dead, thus making the whole thing unusable.

    I’ve revived a Dell Venue battery the laptop reported as dead. Connecting several alkaline batteries in series to provide a voltage slightly higher than the Dell battery’s rated voltage and using them charge the Li-ion battery did the trick. After charging the Dell battery for about 10 minutes I reinstalled it, the laptop recognized it and it worked normally from that point on.

    There’s a trick I learned for drone lipo batteries where if you have low cell voltage, you can set your charger up to charge a different battery chemistry, I think NiMH but don’t quote me on that, charge it for a little bit and then switch it back to lipo mode. No idea if it would work here.

      Nice trick but there’s a reason the charger is designed to not do what you’re getting it to do. Preventing explosions and such. I’d recommend looking up why/how the chemistries are different at low voltage so you can ride the line more safely

        Absolutely. I’ve only done it once or twice, just long enough to get the one low cell voltage high enough to switch back to lipo mode. Also, all the lipo charging I do is inside of a steel ammo can. My drone buddy teases me about it but I don’t care, big and/or lipo batteries are fucking scary.
