Hi Everyone have a strange one here, I've an Acer Chromebook that will not charge off the mains adapter, however if the battery is fully drained it will charge off a usb 3 or a 5v mobile adapter. The power adapter also will not power the chromebook with the battery discharged or with the internal battery disconnected. If for any reason the charge cable is disconnected from the 5v source it will not charge until the battery is fully discharged again!

The solid orange charge light will only come on if its charging from the 5v source after the battery has been drained, otherwise when I actually get in to the OS if briefly flashes orange then goes out. I hope this makes sense.

I have tried all the recommened fixes like disconnecting the battery and holding the power button for 30 seconds etc.

Thanks Nick

    That's typical for 5V adapters, they can't provide anywhere near the full 45W needed for charging, so they charge very slowly when the laptop is off and lose charge slower than with no charger when the laptop is on. It sounds as if your stock charger (which outputs 20V@2.25A for the 45W) isn't working.

    The thing is the charger works with other devices, it even powers my soldering iron too.

    Also when you unplug the 5v charger it will not charge again if unplugged until the battery is fully drained.
