Then today (the next day), the same thing happened, only this time it did start up after only a few pressing-the-power-button tries-again when I held it down.

It was as though it were frozen, apart from the blinking light. I tried pressing, pressing and holding it down, pressing and holding it down for quite a while-nothing happened.

But its power light was flashing (blue, if it matters-that's its usual color), and when I pressed the power button, which usually makes it shut down or start up, nothing happened.
