Hi Severin,
Remember that the screws are captive - they only loosen, they remain with the
cover - so it won't be noticeable that they are unscrewed until the cover comes
off.
I purchased many years ago and still use today, a Newer Technology 11-piece
Portable Toolkit which includes:
• Three Torx screwdrivers (T6, T8, and T10)
• Two flathead screwdrivers (1.8mm and 3.0mm)
• Two Phillips screwdrivers (#00 and #2)
• Two nylon spudgers—otherwise known as pry tools, useful for opening
iPods or Mac minis or removing the top case from an older MacBook Pro.
• A set of large tweezers, perfect for fishing out the screw you
accidentally dropped into the innards of your laptop
• A scissor clamp for holding cables and other thin objects in place.
I would be lost without this little set of computer tools.
Cheers,
Ronni
