So what my laptop should do automatically is to stop charging once it hits ~90%, and start charging again when it hits ~40%. And the OS should give me an easy-to-reach option to "charge to 100%" for when I'm about to make a trip. Why hasn't anyone implemented this yet?
- silverlake 12y agoMy Sony VAIO had this 7 years ago.
- IE6 12y agoYeah my thinkpad did this from the same vintage but that was only on Windows. I think quality of battery management on other Operating Systems is varied...
- SmellyGeekBoy 12y agoMy ThinkPad E530 (1 year old) has this, it's part of Lenovo Power Manager. Again, only on Windows (it doesn't charge at all in Ubuntu, which I've never managed to get to the bottom of)
- tertius 12y agoI have this as "conservation mode" on my Lenovo Yoga Pro 2, and probably all new Lenovos.
- misnome 12y agoMacbooks have also done this for, like, forever, but more with the top few percent than 10%-60%
- gpvos 12y agoYeah, it lets it drop to about 97% before it starts charging again. That doesn't really count, although I guess it's nice.
- cmavr8 12y agoYes this is not real battery care-taking. Ubuntu does it by default like that (I guess linux kernel in general). Although the low and high thresholds (97 and 100% resp.) are adjustable.
- jen729w 12y agoSee Siracusa's analysis of this suggestion. http://atp.fm/episodes/33-a-30-minute-skip-button http://atp.fm/episodes/33-a-30-minute-skip-button TL;DR: good idea, but people will forget and become shitty when their laptop isn't at 100% when they go on a trip.
- cmavr8 12y agoYou're right. Someone should have done it in each OS. In linux it's just a matter of echo-ing a few numbers to the write "files". I just made a script to do it, see my other comments here if interested.
