Answer 1

Tanner,
Your Lombard can run a maximum of 512MB of RAM (2x256MB). The memory module for the top slot is standard height which is approximately 2.0"; the module for the lower (bottom) slot is low-profile, meaning 1.5" or less. The standard height module will only work in the top slot; the low-profile will work in either slot. Also, these 256MB modules are unique to the early iMac, Wallstreet, and Lombard; generic 256s will not work properly.
Generally, when a powerbook's sleep light comes on when either a charged main battery and/or a power adapter is connected, and a power manager reset does not resolve the issue, you have some other hardware problem. Since the 'book is not even turned on, bad RAM would not cause this. If memory were bad, you may or may not get the startup chime, but then you would receive a dialog box on the lit display of a problem with RAM or cache memory in 9.x; OSX does not have this dialog box but nonetheless the POST (power on self-test) still runs.
When you get a power adapter, I would try this:
-remove all power;
-remove the optical drive;
-lift off the keyboard and very carefully disconnect the keyboard ribbon cable;
-disconnect the rechargeable backup battery (PRAM battery);
-lift out the microprocessor card, remove both memory modules;
-disconnect the HD ribbon cable from the logic board;
-reinstall the microprocessor card without any memory;
-connect just the power adapter, then press the power button; if no response, press the reset button on the back panel, then try the power button.
In the above, you have stripped down the powerbook to its bare essentials for a power test. If you have no hardware problem, you should have no light steady sleep light and when the power button is pressed, you should hear 1-beep...no RAM detected.

If the above produces no positive results, then you have a failed component somewhere.
