Does it otherwise turn on, and do you have an OS installation CD?
Older PowerBooks could easily boot Mac OS 9 from USB media, but it was slow going, even in OS 9. Officially, these systems will not boot anything off of USB, but unofficially, you can do it if you muck about in OpenFirmware.
But supposedly if you put an OS there, it'll work? That information's old so I'm not 100% sure on it, but it may be worth trying if you have the 10.3/10.4/10.5 install media and a USB hard disk.
If you have a new disk available and you suspect the disk of being dead, the easiest thing will be just to install the new disk.
