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.
Just because it changes from current to chemistry and back doesn’t change age the fact that the laptop is powered from the battery while it’s being charged…. The charger is supplying no power to the laptop, just through the battery. So if current can’t go through the battery… how could it be receiving power…?
Think of it like a water tank connected to a “T” in a hose, when the tank is partially empty some of the water from the hose will go into it, but once the tank is full the water just continues through the hose bypassing the tank entirely.
Once the battery is charged current goes directly from the DC power supply to the laptop electronics, like the example with the hose and tank it just bypasses the battery entirely because the battery is at the same potential as the power supply.
Batteries don’t have an ‘input’ and ‘output’, they just have a single connection.
I’m just not gonna even address the first parts, that’s only true on some cases as I have pointed out multiple times now, not every device is the same….
…….
All batteries have two connections…. A positive and a negative. You clearly have no idea what you’re talking about here.
