I too spend a great deal of time repairing laptops. I'm currently using this one:

I have a few of these electric screwdrivers (for work and home). I used Dewalt's old 7.2v model for many years but it was just too bulky for precision work. This new 8v is less than half the size though.
I's got WAY more power than needed for such a task but once I got the feel for it I became exceeding efficient with it. It's certainly not a tool I would recommend to a weekend hobbyist to use on their laptop, but if you're accustomed to doing this type of work its a great device.
The only real down side is that you'll have to use an adapter if you rely on smaller precision bits like iFixit or Texton size. Fortunately, I've been able to find all of the bits I need in a standard bit size. YMMV.
My goto tool is my Dewalt Gyro Screwdriver This works like magic. Just a twist of the wrist allows you to forward and reverse at an adjustable speed. And it NEVER overtorques. From motherboards, furniture, and heavy duty use, this just magically knows when to stop and prevent stripping of screws.
