1.5 amps of 120v AC is 180 watts. Amps multiplied by volts equals watts.
Some power bricks are rated at lower voltages than 120 such as 110 or 100.
For $50 you can get a universal Auto/Boat/Airplane DC-DC power adapter for a notebook.
Depending on you model notebook, 12vDC power adapters cost less than $20 at buy.com.
