I set the brightness on my tablet display below half. When the processor gets warm it gives the message "Brightness throttled...

Here is the thing. Acer will switch to battery when the battery is fully charged. This will switch the sleep, and Power settings to battery mode, despite of the fact that you have it plugged in with the Charger that was included or not. This means that if you have the settings between battery, and "plugged in" set differently, the Acer will default to the battery sleep settings. The switch control for this is in the hardware, not the software, and not user servicible. It causes display glitches and disrupts both Bluetooth, and Wi-fi as it switches between battery, and charger. It will do this even if both sets of settings, are the same.

I got this problem when I did not let the device fully charge the first time I bought one. Only thing that worked to fix it was to do a full reset, and leave the device completely shut down, while plugged in over night.
