well are they "stuck" or stripped? if they're stripped...i'm not sure. the screws are countersunk to the point where you would not be able to easily dremel a line for a flatblade.

if the teeth of the screws are still in good condition then you might try some WD-40. its worked for me in the past.

keyword is some. just spritz a little into the holes and shake the laptop a little bit to work the stuff down in there and let em sit for a minute or so. then try again.
