Hello I have Asus G1S

I guess this is a bit late and hopefully you have solved your problem by now, but I just had the same problem with my G1S and the following solution worked for me:

Turn off your laptop, take out the batery and remove the AC cable. Leave the laptop just like that for a few hours. I left mine for 5, but it may work with less. This should clear out your CMOS and take it out of the stuck stand-by mode, since that seems to be the problem. Afterwards just plug in the AC cable and turn it on :)

Hope this helps,

Try to do this:
1. Open and close laptop.
2. Push the PWR button at the front. This starts windows and launches media center. Now it should be back to normal.

Note that the problem will keep reappearing.

You could leave it off for a few hours, but there is a much faster solution that does pretty much the same thing. Turn your computer off, unplug ur AC and battery. Then press and hold the power button for about 15 seconds. This will drain all of the power remaining in ur computer. Then plug ur ac adapter back in and it should be fine.
