The PowerBook 145, manufactured by Apple Computer, was a speed-bumped PowerBook 140, increasing the processor speed from 16MHz to 25MHz. The standard hard drive was upgraded from 20 MB to 40 MB. The 145 also introduced a new feature for the battery-conscious; users would be able to program the 145 to sleep or completely shut down whenever the clamshell unit was closed. Though a direct descendant of the 140, the 145 was actually the replacement for the PowerBook 100 as the low-end model, the 140 having been superseded by the new mid-level 160.

It was replaced by the PowerBook 145B in June 1993. The only codename for this model is Colt 45.

The Apple Macintosh PowerBook 145 features a 25 MHz 68030 processor, 4 MB of RAM, and either a 40 MB or an 80 MB hard drive in a compact portable case with a 9.8-inch monochrome passive-matrix display.
