Hello guys! I need a little help, I have one laptop for repair, it is an Aorus 17G YD, gaming laptop. Broken display, some cable ripped form daughter board connector, case broken, battery discharged and probably locked, etc. After I did the most tedious job I ever did on soldering back the broken cables (shielded cable) , I measured resistance on CPU and GPU core, 3 and 5 v ps and any coils I find on the board, everything seems to be fine. After I plugged the charger I don't get the power led light on from the charger connection maybe because the battery is locked , but on power button I have 3.3v, if I press it, the laptop awakens, power on led on, fan spins, cooler warms, the rgb led from the keyboard lights, and I get display backlight on. On the display connector I have 19v, 3.3v present etc. Ive tried to connect an external monitor on HDMI or mini DP ports and from the keyboard I press Fn and F5 to toggle from internal to external display but I get no picture from the external monitor. I plugged an external keyboard, and I get caps lock and num lock toggle. What sould I try more to get picture on the external monitor so I can know that the laptop is good and after that, buy the replacement display and maybe the case. Thank you!
LE. I've managed to unlock the battery, some of the cells were over discharged, and the thermal fuse was melted, now I have charging led on, and if I unplug the charger, the laptop stays on! I've measured the eDP connector (40pin) in resistance mode and in diode mode, with internal display attached, stdby and pwron and I get like this: 1-Stdby OV pwron 1.72V ,2,3,4,5-OV(probably NC) , 6-3.3V , 7,8,9-gnd , 10,11,12,13-19V ALW, 14,15 gnd, 16, 17-3.3V, 18 without display I get 0.024V with display and pwron I get 2.94V, 19-gnd, 20,21,22,23-3.58V ALW, 24-gnd, 25,26-0.59V pwron, 27-gnd . 28,29-0.022V, 30-gnd, 31,32-0.022V, 33-gnd, 34,35-0.022V, 36-gnd, 37,38-0.022V, 39-gnd, 40, only resistance 1.2K
From 25 to 38 there is eDP pairs,probably 25 si 26 eDP AUX line and the rest eDP data line. No eDP AUX and eDP data line is shorted to ground. The arrangement of pin is al litlle strange, because the panel is without microphone and camera, it have 300Hz refresh rate, I think no pwm backlight adjustment. etc.
So, how do I get the laptop to toggle from internal display to mEDP external port or HDMI port, from FN-F5 combination key from keyboard? Sorry for the long post! Thank's!

But today, I’m making an exception here. Why? No idea. Perhaps only because the repair details are still “fresh” in my head… which is ironic, given this is a 16 year old monitor that hardly anyone will care about today. It is new to me, though. 
I picked it up last November from someone on my local Craigslist. It wasn’t very close to where I live, but was close to a family friend that I had to go visit anyways. So after watching the posting on Craigslist for a few weeks and seeing it getting...
