From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

is there any program to force a linux based OS or a mac to only use outlet power and not battery power, even if I cannot physically remove the battery? (linux.community)

more questions about the MacBook Pro, Core i5, 2.8 GHz (I5-4308U), model A1502 (EMC 2875), a model where I cannot disconnect the battery, because the whole case is closed, a model Im going to use to experiment with mac and create a partition to install a linux distro alongside the mac os.

My favorite notebook is a one that lets me take the battery off if I don't need it. This way I've been able to need just one battery in the last 8 years. Regarding the mac, I'm going to need a new battery (it lasts 5 hours the most) and don't want to waste charging cycles.

My question is twofold:

Is there any linux program that lets me manage the battery so I can choose to rely solely on outlet power, even if I cannot physically remove the battery?
the same question for mac.

You are not wasting charge cycles by leaving the battery plugged in. it is not being held at optimal charge for storage but it will last a lot longer plugged in.

It would be the worlds stupidest engineer that would design a power circuit attached to a potential class d fire hazard that had access from anything other that possibly contact pads on the controller itself. If i were a bad actor and the os has a way to access the charging circuit i would firebomb your house by telling the controller the battery is empty and have it over charge. This would be bad.

Note: I see that apple may have done the dumb and i am facepalming

There are a number of commands an operating system can safely give to the charge controller. Examples include:

Run the device from external power; do not charge the battery
Limit/taper charge to X percent/voltage (assuming X is under the maximum)
Limit the charge rate to (something under the maximum)

Lower-level control could potentially allow extremely dangerous operations like unbalancing the cells or overcharging the battery, which would be bad.
