Thank you for your post, Intel does not yet have any driver for Windows* 8. (No ETA yet). If you got the laptop with Windows* 8 Preview installed you or if you upgraded it from the original install then you might have the drivers on the recovery partition. That would mean to reload the original Operating System save the drivers and then test them.
Note that the laptop manufactures commonly customize their Operating System and drivers for optimal performance. If you use a retail Operating System and generic drivers you may get different/unexpected behavior.
