Toshiba L50-B1Q0 mb: DABLIDYB8C0 rev. C) can I turn it on without power button?

[DS-1]

Hi guys,

I've found this Toshiba laptop with the screen broken for few dollars, it came with ac adapter and battery too, but without power button.

The laptop shows white led if I use ac adapter without battery and orange led with the battery on, but I dunno how to try to make it starts because I have the flat but I don't have the power button.

The mb is DABLIDYB8C0 rev. C and the flat is a 4 pin one. Can I try to make it turns on in anyway?

Thanks in advance for the reply!

The power button when pressed connects a voltage of 3.3 V (usually 3.3V) with ground, the EC (embedded controller or super I/O) detect this change a start the "power sequence".
I tried to download the schematic for you but I don't found it and probably is not available
But if you find the power button connector on the motherboard and with a multimeter (black on ground and red on a pin) identifies the 3.3 V on a pin .
With a wire , short it with ground and the notebook (if it work) turns on. It's possible that there are two 3.3v so do not hold the wire too much time on the ground.

I've found the 3.3v point. I did the short from 3.3v to ground but nothing happens. The led continues to stay white.
