AC Adapters for PowerBook Duos may all look alike, but they're not all the same. Apple just introduced a new unit, with item number M4174LL/B, which works with the new Duo 280 and 280c models, as well as all previous models; it replaces M2781LL/A, introduced earlier this month, which also works with the new and old models. The M4174LL/A adapter works only with the Duo 210, 230, 250, and 270c models. The new item number for the adapter that works with all Duos was probably adopted in order to avoid confusion. Nice try.

Increase Boom Volume Quickly
If you're using Boom to increase the volume on your Mac, you can change the amount to which Boom increases the volume quickly in two ways. Either use the slider available from Boom's menu bar icon, or enable and set hotkeys (Command-Shift-+ and Command-Shift-- by default). Then, when you need that push to 11, more volume is available at the click of the mouse or tap of the keyboard.
