charging prohibition option. If there is no problem with the
hardware, the battery can be charged.
2. Poor contact of the battery interface
Solution:Reinstall the battery interface and ensure that the
battery interface is in good contact.
3.After the weather is too cold, Mac's power supply will have a
certain protection mechanism. The protection mechanism
may cause: automatic shutdown when the battery remains
20% or less or stop charging when the battery remains 85% or
more.
Solution:You can consider raising the indoor temperature
to around 250Cto 300C before charging.
Why does the computer show a lower capacity (mAh) than
advertised?
Watt-hour (Wh) is the energy capacity of a battery, milliam
pere-hour (mAh) is the charge capacity of a battery. The actua
voltage (V) and power (mAh) used by the computer can be
changed. Usually the energy (Wh) of the battery is relatively
constant, which is also the keyto determining the performance
of the battery. In addition, the actual performance of our batter
ies is generally higher than advertised. Calculation method:
The voltage is 12.26V, the battery capacity is 5400mah, and
the actual battery capacity is 1
n a word, Wh gives a more accurate definition of the energy
stored in a battery.
