Apple Macintosh PowerBook 150 - Manual (Page 11)

To set up your PowerBook for the first time, you need the power adapter that
came with your PowerBook.
Step 1 Plug in the power adapter
When you plug in the power adapter, the computer’s battery recharges. You
should plug in the power adapter now in case the battery has drained during
shipping and storage.
WARNING Use only a PowerBook power adapter with your PowerBook
computer. Adapters for other electronic devices (including other
portable computers) may look similar, but they may damage your
computer.
