Yes!!! this worked for me on a Toshiba CB35 C3300 (Chromebook 2016) US Model.
I tried to do it on a second one (as I have 3 CBKS with same issue) but no light at all appears beside the Power port.
Tried to reseat the PWR to MBD cable too but FAIL.
Thinking of calling toshiba support *cringe* for a replacement.
