Same here with two devices:
1. Noname Tablet, Allwinner A10, Android 4.0.4
2. Huawei Ascend G700, Mediatek MT 6589, Android 4.2.1

Quick and dirty workaround:
Set "Stay awake" under Development options, connect charger over night and switch off display with power button.

This is working with both devices.
