I'm using my laptop (ASUS G73JW) with external monitor.
The OS is Windows 7 ultimate 64.
I set to "Do nothing" when the lid is closed and "Never" sleep in power settings.
It never goes to sleep even if I'm doing nothing with my laptop for a long time.
But it goes to sleep in random time when I start to play video with media player, even if I keep doing somethng with mouse or keyboard.
I tested with various other media players, but symptom is the same.
I'm not sure if this is the same on other laptop models/vendors.
It seems like a bug is in Windows kernel drivers or ASUS specific drivers.
Anyone has an idea how to fix this problem?
