Laptop doesn't resume from suspend if connected to power supply

Hello,

I'm getting a weird bug here..
If y suspend (I use pm-suspend) while the laptop is running on batteries, then I'm able to resume just fine (with or without the power plug pluged in at the moment I resume). But if when I suspend, the laptop is connected to the power plug, then it will freeze on resume (black screen, "suspend" led light on but fan spinning).
I guess it's something caused by the "laptop-mode" scripts but cannot find what.

Does anyone have any idea about it?

Thanks a lot

My lappy, like many, would not resume from suspend unless I added resume and deleted autodetect from my mkinitcpio.conf, then regenerating the image through #mkinitcpio -p kernel26

Similar thing happens to me too. Irregularly cannot wake the machine whan on AC power. I can wake it every time when running on batteries. The phenomenon occurs about 50:50, I would say.
