Bear in mind that this voltage is passed from the diode inside the MOSFET Q7155. PPVBAT_G3H_CONN passes the internal diode of Q7155, charging current sensing resistor R7150, fuse F7140 and becomes PPBUS_G3H power rail.

In other words, the battery output will remain close unless a 10KΩ resistor is detected. The smart battery internal circuit detects the presence of the 10KΩ resistor, then opens the battery internal MOSFET to output the battery voltage. When a battery is connected to the logic board, a 10KΩ resistor R7050 is connected to the battery connector J7050 pin 15.In order to answer this question, we need to understand the principle of the Apple MacBook charging circuit. If you used Disk Utility from macOS Recovery, you can now restart your Mac: choose Apple menu  > Restart.Why the faulty R7050 caused MacBook battery not charging? – Understand the principles The order of repair in this example was Macintosh HD - Data, then Macintosh HD, then Container disk4, then APPLE SSD. Keep moving up the list, running First Aid for each volume on the disk, then each container on the disk, then finally the disk itself.

If you're asked for a password to unlock the disk, enter your administrator password.Īfter Disk Utility is done checking the volume, select the next item above it in the sidebar, then run First Aid again.If the button is dimmed and you can't click it, skip this step for the disk, container, or volume you selected.If there is no Run button, click the Repair Disk button instead.In this example, the last volume on the disk is Macintosh HD - Data.Ĭlick Run to begin checking the selected volume for errors. For each disk that you're repairing, start by selecting the last volume on that disk, then click the First Aid button or tab.
