No. You may just need to do a power manager reset 
(Command-Option-Fn-Power, or whatever the keys are listed as on the 
port panel on the back) to rewrite the corrupted PMU code (after the 
main battery is charged), or:

- your PRAM battery is dead or shorted *
- your PMU board is defective *
- your motherboard is bad *

* = requires extensive disassembly of your machine to replace

The correct procedure for rewriting the PMU code is on 
accelerateyourmac somewhere if the power manager reset doesn't fix it.
