While replacing my SSD
, I managed to strip a screw. I used the Dremel approach to remove the stripped screw, as the screw head was above the level of the PC board. I used strips of cardboard to keep the filings out of the computer, and they worked well. You could also use plastic wrap, duct tape, etc -- whatever your level of paranoia calls for
The Dremel worked like a champ. I was surprised at how little cutting it took, and how little effort it took to remove the screw with the flat bladed screwdriver when the slot was cut - I guess that a screw made of metal soft enough to strip that easily is also going to be easily cut with a Dremel. Have a magnifier on hand when working, or try the screwdriver in the slot frequently while cutting.
Whenever you are cutting metal, keep in mind that you will
get metal filings, whether you use a hand file, drill or Dremel. Always mask off the electronics to keep the filings in check, and consider running a magnet over the area afterward.
The opening in the bottom of these mini laptops is pretty small. Most hand files are going to be difficult to use in the enclosed area you will have, whereas the Dremel needs only enough space to fit the cutting disk.
