Hi there,
My laptop refuses to turn on and all lights are off… did the hard reset, (refresh + power button for 30 s), bought a new charger..nothing is happening….
Is anybody know what it could be??
Thanks

Hi,
One possibility is that the input power jack to the laptop could be faulty and therefore when you connect the charger nothing registers in the laptop.
Also if this was the case if you kept using the laptop on the battery only (or even with the charger connected and didn't notice that it wasn't charging the battery) the battery would eventually go flat and you then couldn't start the laptop either.
The laptop would have to be opened and the circuit checked from the input power jack to the motherboard.
If that was found to be OK after that further testing would be required to ascertain what the problem is.
What is the full model number of the laptop?

Hi,
Thanks for answer. The model of my laptop is CB3-431-C69V. ACER Chromebook 14.
Thank you for your help.
Hi,
Here's a link to a video that may be of some help.
I realize that it is not your exact model number but it is in the same series so it still may be of some help.
It shows how to open the laptop so that at least it can be inspected for any obvious damage to the components.
This link to the ifixit Acer Chromebook CB3-431-C5EX guide should also help to open the laptop for inspection
If you disconnect the DC-In jack - example only from the motherboard connector, you can test it for continuity with an Ohmmeter, to verify whether it is faulty or not.
If it is OK you'll have to delve further into the problem.
Not an easy task if you haven't got a schematic of the motherboard
