    Acer ES1-711

    hello everyone,i have a mentioned laptop with the board DA0ZYLMB6D0 rev: D

    laptop turns on, but no picture,all the voltages present,CPU cold,USB has power,but not blinking the usb stick light, so not reading from usb, fn+esc works, starts to blink power led,but not reading from USB, fan spins up at powerup and doesn't work even if i heat the cpu with hot air...it seems something is missing at powerup,but what... i tried flashing bios a few times, it's 1.8V, and i have the adapter, so everything went fine, but to no avail...could the EC bee the problem? how to flash EC?

      If all voltages are present, cpu cant remain cold. Check voltage on coils near cpu.

            It has nothing to do with crystal.
