Quick Tip – Common Macintosh PowerBook 100 series issues

If you own a Macintosh PowerBook 100 series laptop, here are some of the common problems that you need to watch out for:

Case plastics – The plastics used for the case of the PowerBook 100 series laptops can become brittle over time, which can cause the screen hinge assembly to break away from the case or screen.

Rear port door – For some reason, Apple chose to locate the power button behind the rear port door. This door therefore needs to be opened each and every time that the PowerBook is switched on, and this can cause the door to break off due to the plastic becoming brittle over time.

Ni-Cad batteries – The Nickel-Cadmium batteries used on the PowerBook 100 series will fail with age and use (although the internal cells can be replaced), and they can also corrode their battery terminals if left for a long period of time inside a PowerBook.

Screens – The active-matrix screens used on the PowerBook 170 and 180 can show darkening of the corners after being powered on for a few minutes. The passive-matrix screens used on the PowerBook 140, 145, and 160 can turn completely black due to failing electrolytic capacitors inside the display.

This video applies to the following models of Macintosh Powerbook:

The PowerBook 100 and 190 series laptops are not covered, as they have a different case design.
