Chosen Solution
I recently bought a replacement battery from here and now it randomly shuts off both at high and low percentages. Sometimes if i persistently click my trackpad it will “wake up” but other times it does nothing and I have to press the power button to turn it back on. I already:Calibrated the battery on install.Resetted the PRAM.Resetted the SMC.And used this command line:mv /System/Library/Extensions/AppleThunderboltNHI.kext /System/Library/Extensions/AppleThunderboltNHI.kext.BAKNeedless to say, nothing worked so far… If anyone has any suggestions, thanks in advance!
The MagSafe charger appears to be charging at a low rate. If you didn’t wait a bit you might have not caught it being more active. Otherwise you could be using a bad charger. Make sure you have a healthy charger the cable is not damaged or shows any bumps if it does you need a new charger
You can’t tell the real from the knock offs! So you really need to go directly to the Apple Store or order online directly from Apples site: Apple 60W MagSafe Power Adapter (for MacBook and 13-inch MacBook Pro) Also inspect the connector interface make sure it is clean. Not like the top one, use a Cotton swab (Q-Tip) with some isopropyl alcohol
Also make sure the contacts aren’t damaged like this one
Thats a sign of a knockoff damaging your system! Please don’t buy a cheap knock off unit as they will damage your system! Only get the REAL Apple unit directly from Apple.
