我有一台 2012 年中期生产的 13 英寸 Macbook Pro。我用售后电池更换了电池,虽然可以使用,但是使用寿命不如原装电池。
最近,由于另一个问题,我重置了 SMC,现在我的电池百分比显示不正确。充满电后,它会长时间保持在 100%,在 50% 左右时会突然关机。当我重新打开它时,电池电量显示为 0%。
到目前为止,我尝试再次重置 SMC。我尝试两次耗尽电池电量并重新充电至 100%,但问题依然存在。
以下是我上次出院的结果:
11:30 100%
11:53 96%
12:12 83%
12:47 59%
12:59 52% (shut down)
13:00 0% (plug in - turn on)
