Several of our schools are using the same model.  Only seen this once before.  One item to look at if you have not already is resetting the LVDS cable at both board and screen ends.

Do you think it is the battery/power issue or screen?  Does the charge light go from amber to green after it has been "charged" for a while indicating a good battery, but the power throughput to rest of the device isn't working as it should?  I know that with the CTL device that I am referring to it took a while to figure out the cause.

As Craig Donnan has added, CTL support is fairly good at trying to assist with these issues.  My assumption is that you have already gone that route...

Please let me know what "fix" you ultimately use as we have multiple schools running these.

Good luck!

We’re seeing a trend here, and wonder if anyone else has experienced this problem - and hoping someone might have a solution.  

We have 12+  CTL NL6 ChromeBooks that are just out of warranty.  Suddenly, they do not accept a charge.  We’ve swapped chargers, charging ports, and the cables which link the port with the motherboard.  We’ve swapped batteries, and even tried removing the battery from the machine and powering up directly from the power supply (this often works with Macs which have a power/battery problem).  Nada.  

Replacing the motherboard itself is almost as much as purchasing a new machine, so that’s not worth it.
