Now all the books were gone! Aiieee! Fiddled a bit more, and did a reset. Took out the SD card. Plugged it into the USB port. Eventually it came back, and now showed the books in main memory. But all tags and Collections information and memory of where I was in various books: poof!
Now I've got it back on USB charging, with the SD card back in. (It had not indicated a low battery--down maybe one bar.) It shows up in Calibre now, but only the main memory--SD card is invisible--and all the tags are missing from the books on the Reader.
So I seem to have clobbered the database somehow, and maybe knocked out the SD card, all in one go.
Any suggestions on how best to put things right?

I've never used Calibre and I have the 550, not the 700. But it's been my experience that by performing a reset the collections will disappear on the Reader. Also, I found out early on that any time you remove the SD card from the Reader the collections are also wiped out (although the books are still there.) In my case I have to sync the Reader with the Sony Library, which has my collections sorted out, in order for the collections to reappear on the Reader and SD card.
I have about (just under) 1500 books on my Reader, divided between the Reader natively, the SD card and the MS card. It's been my experience that when I sync my Reader and unplug it from my computer it seems to take a long time to repopulate, or index all of the books, thus I don't sync it very often. I use the AC wall charger that came with my 500 to charge the Reader because by the time the Reader is finished going through it's paces and showing all my books and collections (from the sync action) the battery is usually already down one or two bars and so needs to be charged again soon.
This indexing (I'm sure there's a better word for it) is what uses alot of the battery power, so I try not to plug it into my computer very often unless I have SEVERAL books to add to the Reader at once. Otherwise the result is a vicious circle of charging via USB, unplug the Reader, wait a long time for the Reader to re-index everything, and by then half the charge is gone already. I wouldn't be without the wall charger (a very important accessory to me.)
Also from my own experience, I found I need to be more patient with the Reader when it's indexing after unplugging from the computer. It DOES seem to take forever with so many books on it, but you can't rush it or unnecessarily think something is wrong, when there isn't. Also, I've found that when the arrow on the screen stops spinning and the Reader still doesn't show the collections, just leave it alone and turned on. I've found that the arrows will start spinning again and the next time it stops all the books and collections will be there. I used to get frustrated because I thought it wasn't working right but found I just had to be very patient (probably because of having so many books for it to index, I don't know.)
As for prolonging battery life, I'm sure the 700 uses power more quickly than the 500 or 550 simply by using the integrated light. But on my Readers the power lasts a very long time when just reading. I don't even bother turning it on and off all the time. If I'm reading and I lay it down somewhere expecting to pick it up again and continue reading anytime soon, I just leave it turned on. If it sits long enough without turning a page it will turn itself off after awhile. No harm done and no extra power used.
Since I don't know how the Reader works or reacts with Calibre, my soap box dialog above probably didn't help much. I'm sure someone with Calibre experience will be along shortly to help you out.
Don't fret. I'm sure help is on the way.
Oh, and there's no charge for the questionable usefulness of the above information.
