You said it does power back on, so it might not be completely dead.
If you have any CDs, DVDs, or other types of disks in any of the drives, eject them when it powers on and try starting it again.
No discs in drive at all. I did try inserting the OS disc and power cycling, but nada. And I have had the battery out of all power cycles.
If it made all the right noises and the disk lights up, and the cd drawer opens and closes, it's not dead.
There's a chance you blew the display power supply, which is replaceable for less than $200, which is probably less than your insurance deductible.
Just hold a bright light near the screen, turn the laptop on and look for faint letters and images. If you see stuff, it's a display problem (power supply or lamp). If not, it's something else.

CD tray opens, but no noise. No deductible on State Farm's PAPolicy. Tried a C4 dive light on the screen; ever shine your light across a large room in a cave dive? Dark!
One friend suggested leaving it unplugged for 24 hours, to make sure there's no charge left in. Alternately, open the case, remove the internal battery, and toggle the CMOS switch off for at least five minutes, then toggle it back on, replace the internal battery, replace the case, and replace the main battery pack. I think leaving it all unplugged for 24 hours would be easier.
I tried my spare power cord: nope! [-]I need to ask about power surges, but[/-] I've never heard about State Farm denying a PAP claim even on flooded dive cameras, which is why I ensure my all of my cameras, O2 & CO analyzers, both dive puters, that laptop, etc. with them - and it's cheaper than DEPP or DAN equipment.
Edit: Power Surges Covered! But thanks for the heads up.
If I do the claim, I'll put the original HD back into it, move its HD to this laptop to update my back up. I generally back up all documents once or twice a month to an External HD, but as busy as I have been on the farm haven't since July 7. Eh, if I had stored anything important I would have backed up sooner; I may not even bother with that but then it's so easy. My first HD change took a few minutes, but since then - fast.
