From what I heard from the RendezVous, the Cybook is put in a state in "sleep mode" where the only way it could drain less battery is completly off.
On "standard" computer sleep and standby is normaly the same mode, ie CPU at lowest consumption, HD/DVD and other peripherals at the lowest consumption, and RAM in a special mode that will retain informations without need of an external device (Self Refresh mode) The only mode that can go further than standby is "herbernation", unlike the standby mode, the RAM content is stored on a fixed drive (like a HD or anything else) and then the computer is turn off, and the next boot is a special one, where it read the special file on the HD and restore the RAM content. By seeing the time the PRS505 and 700 turn back "on" from the "standby mode" it doesn't look like they use such a thing. |

The interesting question is probably how it wakes up. I suspect it is by polling since otherwise it would be very hard to miss button presses and we know that happens.

Agreed, whereas perhaps the Sony uses interrupts, in which case the hardware could be put into a much "deeper sleep".

now you can see a video of the fast advance (on the Opus, but it's the same idea on the cybook, just without the accelerometre) :

I doubt they use pooling or else a standby mode is not possible. Key should be driven by interrupts not by pooling their values.

Don't you think that the fact that the Gen3 occasionally "misses" key presses is a strong indication that the o/s is polling the keys? Interrupt-driven key presses should never be missed.

Mine cybook had never "miss" any key. Maybe this was due to hardware bug? Or maybe a software bug, since when you get an interrupt, until you finish the treatement of it, you will not get any new interruption. This will mainly depend on the used CPU, but interruptions are generaly masked when you treat one. So it's possible if there is a bug here to miss some interruptions.

And when they tried to fix that problem the battery time went from 6-7 days to 2-3 days. Then they did something so we got 4 days battery time.

And after they set this back to 6-7 day. The bug that led to lose 4 day could be due to something else

So, effectively, they made a new firmware for them to make a deal with Weltbild and now release it also for existing customers. It's not that I don't appreciate the fact and welcome it but it's not as selfless as you put it, either. Quote:

Bookeen struck the huge deal with one of the largest publishing groups in the german speaking market and therefore had to put out a fw with ePub support. The fw was for them to be able to get a deal with Weltbild and has nothing to do with their evaluation of how many german language books there are for sale in any given store. Quote:
I am happy that they improved the display driver and am looking forward to a more responsive Cybook but I very much doubt it's anthing close to doubling the speed. Sorry, if I can't share your enthusiasm but I would rather first see the fw delivered and working as intended before I throw roses at Bookeen's feet. I have already experienced 3 fw updates: The first halfed my battery time and then it took two more updates to bring it back to what it was in the first place. This time I wait with applause until I can see for myself what I get... |

I have developed my own strategy, though. I press the button when I get close to the train/bus/subway station and once I am there it's finished booting. During the ride I don't switch it off even when I change transport (have set auto turn-off to one hour). That works pretty well for me so I don't mind the boot time. |
