Cautionary tale: Macbook Pro in the shop. I keep a tidy shop. A messy shop is a dangerous shop, so I do what I can to clean it regularly. I have 3 workbenches: My carpeted electronics bench, my "workbench" (heavy work) and a wall-mounted "fold-down" butcherblock-style bench which is mostly for layout & design work. That said, while each bench has a purpose, any / all of these might see electronics, drilling, grinding, etc. While I strive for cleanliness, none of these tables could be called "operating / clean-room clean". That's just not possible. Today, my Macbook Pro is a goner. A victim of my "clean" shop. I always thought Apple's power connector was pretty nifty! Having tripped over PC power cords (resulting in torn plugs), the magnetic "break-away design" of the Mac struck me as ingenious! Well, I used my my MBP in my shop yesterday (something I've done a million times), and the magnetic power receptacle "sucked up" a dinky little piece of steel bench detritus....unbeknownst to me. When I went to charge the MBP, the little LED in the plug didn't com on. An examination reveals a shorted, burned up receptacle and a dead power supply. Lot's of burn marks & fried contacts. Be careful out there! Learn from my mistake! The piece of debris was not much larger than the head of a pin...but that's all it took. Since you're unlikely to ever rid your shop of detritus that small, my suggestion: your MBP should not go into the shop. Or maybe a piece of gaffers tape over the receptacle... Something! My 2 cents, /rant.
