So I am working on my grandson's chromebook which he says is broken. Upon receipt from him it would not power on, or seemingly charge. As a long time IT guy, I found a 5V 5.7a usb C charger in my collection, and upon using this charger the device charged and powered on. Ok great, charger must be bad. Ordered a new charger, specifically compatible with the CP311. It appears to be similar to the original, and the output listed is the same. 5v/3A 9V/3A 12V/3A 15V/3a and 20v/2.5A 45W charger. The new, compatible charger does not work. It would appear that the device is needing the 5V5.7A that my old motorola charger provides. As the label is obscured I can not tell what the actual power spec for the device is, so can anyone tell me? Has anyone had a similar experience, or have any thoughts on what is going on here?
