Power on OK, chimes, then text saying, 'you need to restart...'
Powers on OK, chimes, then a gray screen and text in 4 languages saying, "You need to restart your computer... " Stays powered up with that message.
Normal sounds otherwise; chime, fan; HD.
If, I hold down power button through 1st chime, then, a BEEP sound occurs, then, a 2nd chime, then, a black screen and then it powers off.
Boots OK into Disc Target Mode no problem.
I've reseated RAMs. The BATT is good. The Charger is good. Charge circuit works OK.
Is this a good question?

Does this behavior change at all if you hold down the left Shift key while booting, triggering Safe mode? If you hold down the Option key while powering it on do you reach a screen that shows your hard drive? If so then you might try to boot to an external OS (either from an external hard drive, to another Mac booted to target disk mode or to the gray discs that came with your Mac). By holding Option when powering on you should be able to see, and select, any bootable Mac OS that is connected to your Mac.

Yes, it behaves differently:
Holding L Shift key, power on, boots; sometimes it gets past the gray screen with text as above, but after a few minutes the Apple logo becomes a circle with a line across it… and it just sits there.
Holding Option, power on, boots, then HD appears with an arrow beneath. I click on arrow, then the gray screen with the text as above appears.
No peripherals connceted.
You mentioned "Kernal Panic." That appears in dark letters on top of the gray screen. Also "Unable to find driver for this platform" And hexadecimal addresses; more.

Have you upgraded/updated any software recently? Do you have the gray restore discs that came with your Mac? If so you might try booting to those by inserting it into your Mac and either booting while holding the C key or using the Option key method I mentioned above to select your restore disc. If it boots properly to those discs then it's likely a software issue and a disk repair and/or reinstallation of the operating system would be in order.

I have not performed any updates or upgrades. Neither has laptop been damaged: no drops, no spills. I do not have the "gray restore discs." I do have gray restore discs (OSX 10.5.2) that came with another laptop, an A1260, but have not tried them with concern they might not be ejected.
Starting with holding down Option, HD reliably appears but then clicking on the arrow the gray screen appears with text as above, or simply shuts down.
Starting with holding down L Shift key it chimes, gear wheel spins, but then shuts down.
