I have been helping out my local schools by repairing the chromebooks they use for students. I mostly do solder work on the boards since they are becoming harder and more $$$ to find. Several have come in with the same issue.

Off the battery the USB-C port reads 5 volts for an instant then jumps to 14.9-15 volts low fluctuating amps...this is normal. The problem comes in when the battery is plugged in. The volts stay at 5v, but the amps raise to normal charging 2.85amps. The device will not boot. The odd thing to me is that some spots on the board around the battery get 12+ volts....

Could this signify a "brain" issue (CPU, RAM, NAND, BIOS) more than a power issue?

Any reply is appreciated!
