I don't know if this is a software problem or not, so forgive me if this is the wrong forum to post it on.
My Asus Q301LA refuses to wake from sleep mode if the charger is plugged in and the battery is fully charged. To elaborate, all that happens is the light on the power button comes on, but my screen is still blank. I have to force shutdown or force sleep, remove the charger and then wake it again.

Though it will still come on if the charger is not plugged in when I press the power button or the battery is not fully charged. I recently imported it from the US into India, so is it possible it is a power-related issue? Although I am using a proper voltage converter and adapter.
