I use two of these as my go to drivers for computers and anything else "lighter" duty:

DEWALT DW920K-2 1/4-Inch 7.2-Volt Cordless Two-Position Screwdriver Kit

Amazon.com: DEWALT DW920K-2 1/4-Inch 7.2-Volt Cordless Two-Position Screwdriver Kit: Home Improvement

Had great luck with them and the batteries. No issues and they are worked hard.



Also have two of these:

Milwaukee 6547-1 2.4-Volt Ni-Cad Cordless Screwdriver

Milwaukee 6547-1 2.4-Volt Ni-Cad Cordless Screwdriver - Cordless Electric - Amazon.com

I use them for more "micro" work on hard drives, etc. No issues again. Well made tool.
