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.

    I’m sorry but you’re mixing concepts. Electrical charge: measured in Coulombs, physicaly either electrons or gaps. Current: movement of electrical charge. Battery charge: chemical capacity to generate a voltage differential. Voltage differential: the potential energy difference that pushes charges through a circuit.

    Electrical charges need to move through a battery for it to do useful work. If the battery is causing the movement (current), it is depleting its chemical charge. If the battery is not pushing the electrons, it’s likely being chemically charged (the complexities of which are beyond a lemmy comment). In both cases, the battery is part of the circuit that is conducting electrical charge. If there are no parallel paths and you remove the battery, the circuit ceases to exist and so does the current.
