Help me interpret an LED diagnostic sequence

Can anyone interpret this LED diagnostic sequence?
My wife's Toshiba Satellite Pro M10 (the one featured previously) was finally dropped on the floor, and now it refuses to power up. I tried it without the battery - still nothing, so I stripped it right down, reseated everything, and put it back together. Still nothing. The left-most LED (the "plug") is now blinking in a diagnostic sequence, but I am at a loss to interpret it. It was giving exactly the same sequence before I took the machine apart ;)
I suspect the motherboards's been damaged, and if that's the case then it's not worth replacing, but I'd like to know why it's complaining in case it's something relatively easy to fix.
I recorded a movie of the LED sequence; apologies for the low quality.

Response by poster: Thanks, PROD. I did some extra searching based on what you've said, and I think the error code is hex 72. However, I still don't know what this means, as I don't have access to a service manual.

which suggests that the problem is "PPV voltage is not more than 0.68V when the computer is booting up".
Whatever that means!

Gene, here is an abandoned Expert Exchange link that covers the error code that you are receiving.
It is possible that a capacitor may be damaged. That usually spells certain doom for a motherboard. Unless you have a wave soldering machine.

We used to have an enterprise-scale metric assload of earlier Satellites (6100's, but I think they were only a year older than this model). A blinking amber light always meant a bad motherboard.
