I'm glad for the what to do answers, but I'd like to understand why it does this? Is something wearing out? Did the shutdown go wrong?

Hello,
Could someone please explain what might be wrong with a Wallstreet. It is turned off, the AC is plugged in, and the green light at the hinge stays on, not blinking as it would do in sleep.
Green Light of Death (GLOD)
Unplug the AC Adapter, remove the battery(ies) then hit the power button, the green light should go out. Now plug in the adapter, wait a few seconds then hit the power button. If it starts okay then put the battery(ies) back in.
Basically the Power Management Unit (PMU) gets into an incorrect state. It is much like a program crashing and taking the OS with it. In both cases you have to reset to clear it. There is a PMU reset key sequence but I have found it doesn't always work. Disconnecting the AC Adapter and removing the batteries leaves only the PRAM battery. Pushing the power button puts more of a load on the PRAM battery than it can supply (AFAIK there is a protection circuit to avoid damage). This removes all power from the PMU which resets it.
