With the iBook (three models, two CPU series; different builds) one of the resets known
as (PMU) is covered in this archived article from Apple Support. -- Depending on what
model year, build model, order number, or identified by exact means, this reset varies.

Early clamshell first-edition iBook G3 with color versions; then early 'snow' white G3, and
the last build G4 white polycarbonate Mid-2005 12-in (1.33GHz) and 14 in (1.42GHz). Each
of these sections of the product time-line, have different reset methods. Oldest versions of
G3 had 'PMU reset button' in the portable computer. Later build year models no longer did.
Another reset that conditionally (or in process of troubleshooting) may be helpful: Involves
'parameter random access memory' or PRAM. ~ Later Macs use same keyboard keys to reset
a different designator 'non-volatile random access memory' or NVRAM.
Both of these use same keyboard shortcuts and exact timing to implement is required.

Could be the hard drive has failed, if the rotational disc inside has seized or the electronic board
inside the case which supports drive function, has failed, the unit would be bricked. If you have
an externally enclosed hard drive in FireWire case with its own power supply (and chipset made
specific to external drives, that allows them to start the PPC Mac OS from certain drives) that can
be used to troubleshoot. You'd have to either have a system clone from a working same Mac, or
have install-restore system disc to make a new startup system on an external FW HDD.
So a re-set button may be a hoped for easier means, if it worked; otherwise be ready to look deeper.
My last model 'Mid-2005 iBook G4' 1.33GHz does not use separate button for reset PMU. Nor did G3
'white' first edition 2001.

PS: Edit for last sentence above: IF tiny button with triangle next to it by ports on
iBook G3 (white) = is a reset button. ~ However note the conditions of PMU reset
the use of these instructions in the article portray a 'limited use scenario' at best.
Certain fringe models may not have the tiny button. Original articles no longer
show this exact detail; prior to archival status some had images in the articles.
Good luck & happy computing!😊
ibook reset button to fix bricked laptop?
