My yoga 900 wont turn on and the charge light not lit.
I stupidly bought and plugged in a cheap power charger to my Yoga 900. It was going to be my portable back up.
It immediately shut the computer down.
The charging light was NOT lit on.
I then tried to used my OEM charger. The light still doesn't turn on.
I pulled the back cover off and took the battery off. Held to power button for a minute to dissipate the capacitive charge. Reconnected the battery. Still NOT on. Charging light still NOT lit.
I heard that the CMOS may need to be replaced?
I dont think this yoga 900 comes with one?
The manual said the system board needs to be replaced?
It looks like the power port connects directly to the system board.
