Battery problem ?
Periodically, I let the battery drain down, normally I plug in every night
This morning my iPad would not turn on, and in tried re-booting, etc
I plugged it in and after a while it started normally
Battery level was showing at 35%, so I am wondering if this is a sign that something may be amiss with the battery or the machine itself. It is still under warranty.......
Are you plugging your iPad into the charger that came with it or are you plugging it into your PC?
If you are using your charger, then there definitely could be a problem.
You can use your PC to charge your iPad, but it will be much slower than using the charger. The only thing to be aware of when using your PC is that if you have set your power saver mode so that your PC "goes to sleep" or hibernates, this can shut off the power to the USB port and can actually cause your iPad battery to drain rather than charge!
Battery problem ?
No, I was using the iPad charger directly to the wall

When I tried to open this am, itbwould not start up and it was only after plugging it in and waiting for a while that all was OK
I am assuming that the indicator is amiss and that itbwas really fully drained (?)
Once you let it charge back up to 100%, it should be OK. It would be rare, but it certainly is possible that there could be something wrong with the battery.
Battery run down
I had just about the same problem, my battery run right down to zero. I tried to charge it via the wall socket using the apple charger, but it just would not charge. In the end I went to the local apple store and they took it round the back for a couple of hours (they suggested I went for a stroll around the shops). When I came back they had managed to get it charging, but as a precaution they suggested a complete reinstall. Luckily I had backed up all my apps on iTunes so I agreed. Since then it has been ok, but I do think it takes longer to charge than the 4/5 hours they suggest. Nowadays I tend to recharge when it gets down to about 15/17%.
Don't know if this helps you in any way but it has been my experience.
