Hi !
I have problem with Dell 5520 15" laptop.
Laptop has this motherboard ... https://cdn.badcaps-static.com/pdfs/...a856347d78.pdf
When i try to turn it on it spins fan for 3-4 seconds, power led goes on, 3 leds above keyboard (upper right corner) are lit in some sequence and after that fan stops and power led remains on. Screen is black. I tried to connect monitor on VGA port but there is no image. I tried to power it on with battery and charger in a any combination. Result is allways same.
To power it on i have to short pins 3 and 4 on JPWR connector because it also has some problem with power button board or cable.
Anybody has idea what to check first in case like this.
Thank You !
