Point of View Tab P1046 recovery mode

Hello everyone!
I have Point of view P1046 tablet. It doesnt want to boot. Just stay on android welcome screen for a while then shows black screen. How can I boot into recovery mode? There is no volume buttons, only power, esc and pinholle for reset. Adb recovery via pc doesnt work, adb devices list is empty.
Help me please, I am desperate. Sorry for my bad english.
