I have an old MacBook aluminum laptop that got dropped on a corner.
I'd like to beat the dent out of it so the lid will close properly.

I
rounded the end of the screwdriver blade, which was about 3/16" wide,
such that the end is now a section of a thin disc. The radius of this
disc section is slightly less than the radius of the corner. I then
braced the aluminum case with some resilient material and made several
taps on the handle end of the screwdriver while the tool was engaged

I used a
small ball pein hammer that Starret sells which has a magnifying lens
in the hammer head, it was the perfect weight.

That's their "Toolmaker's Hammer". Its intended function is
placing the point of a center punch properly relative to the
intersection of scribed lines using the magnifying glass, and then
striking the center punch to mark for drilling. (Depending on the size
of drill intended, you may want to follow up with a heavier center punch
and hammer, but you can find the previous mark by feel at this point, so
no need for another magnifier. :-)

The single page "manual" accompanying the hammer is fun to read,
too.

Enjoy,
DoN.
