IBook G3 Power problem

Anyone willing to help with a power problem.
I'm trying to get a used IBook G3 to powerup (got such a deal LOL)
I've checked the power suppy w/a meter it reads 24VDC
The power cord lights up when I plug it into the laptop, no other
signs of life.
I've pressed the reset button (above the headphone jack) with power
cord disconnected
Also lifted the keyboard to look for any obvious damage.
Also removed the battery and tried reset and powerup

Any options besides opening it up?
Any advice about taking it apart.........no taking for service is not
an option


Thanks in advance for the help
