Dell commonly uses Phillips #1 for many screws. On various Dell laptops I opened, I think I used Phillips #1 for everything. If you have a good quality bit with clean edges and good taper, a Phillips #1 will likely turn a #0 screw as well. That M2x3 likely takes a Phillips #1 bit. Ensure that the bit fits snugly into the screw receptacle. If it is loose, size up. If it won't sit in the recess sufficiently to turn it, size down. Apply steady, even pressure and turn slowly. Whenever touching components or working inside a computer, wear a grounded wrist strap, also called anti-static wrist strap, ESD wrist strap, or ground bracelet. It's a cheap and sensible precaution. Rest the laptop on an anti-static mat or at least a reasonable alternative such as corrugated cardboard.
