My father’s Acer Chromebook 14 (CB3-431) will no longer power-on. It worked fine for 18 months before one day it no longer charged. Once the battery ran down it no longer powers on. I suspected the power port might be at fault, as the socket is quite loose. When removed the back I noticed a white mark on the motherboard near to what I believe is the charging circuit. Now I am no longer sure whether it is worth ordering a new power port. Does anybody know if this looks like a blown motherboard component?
It’s hard to tell from the picture. A blown motherboard component would have probably made a noise and emitted some kind of smell when it detonated. Also, the computer would have likely become symptomatic immediately. It could be a blown component, or that white mark could be because of a manufacturing defect. Perhaps the unit is refurbished, or was otherwise handled by a technician who damaged it? To make sure that the power port is at fault, I would probably first replace the battery and see if that doesn’t fix the issue. It’s always best practice to try the least invasive solutions first.
