this thread is some yaer old, but we have the same issue with our YOGA 500. white slowly blinking powerbutton (1 Hz). as per manual it stands for sleep mode, but we did not get it out the sleep mode, even not with power unplugging and draining battery. it would take to long.
so i opened the back of YOGA by unscrew the 11 screws and lift of the cover. disconnected the battery cable and plug in the power cord again, ans the note started immeditaly again.
inserted the battery cord again and closed the back cover of YOGA. everything is fine now again.
hopefully for a long time.
