I don't understand your problem. They said me the JBC enter automatically in sleep when you don't use it for 4s. Eink doesn't need electricity to display the page so it make sense for me:

1) you turn the page
2) probably you stay on that page more than 4s and the device goes in sleep: the device informs you on the new state turning the blue light (led?) off above the "menu key"
3) you can read the page even one hour because the device is sleeping now while eink screen shows the page (no electricity needs)
4) after one minute (for example) you decide to turn the page pushing the button "V"
5) the device awakes, it turns the (led?) blue light on and then it turns the page.

If it's all true, you have no need to bother about pushing a special button or something else, just leave the device manage the power for you :-)

But I'll get my Jetbook Color only next wednesday. Then I'll try to solve this issue


P.s.: If you change the settings I don't know what it happens. I suggest you to contact the support for details
