I think i fix it, it was bad bios. I reflashed the bios using tl866ii plus programmer and also flash ec firmware, the laptop now working good again. Thank you..
I have the same problem with this laptop. Is it normal if the switch on pin 1 voltage is 19v? I have changed the mosfet in pq23 because it was faulty and the laptop bootup fine, but there is another problem, the laptop will shut down and start on repeatedly until i turn it off.
