omen 15-ek0000nj does not turn on and no LED lights glow or blink

[odedeizenberg12]

hi!

last night I've updated the system recommended updates from the windows settings as I normally should've, after a very long time that I haven't done those updates. the laptop was plugged to my external screen and docking as I've always had. after a few updates (I think it was the BIOS update) I noticed that the external screen an all the equipment (such as mouse and keyboard...) doesn't work, but the laptop itself was booting normally as always, so I tried to find any notification about why the screen and other equipment didn't work but the system showed nothing, so I've unplugged the USB-C of the screen and equipment from the laptop and when I tried to plug it back in, suddenly the laptop turned off and from this point it does not showing any signs of life, no LED lights, no charging indicator, not the screen of the laptop itself, nothing!

I tried to open it to get to the battery, and checked the AC adapter, the AC jack, and battery itself with a voltmeter- all showed a good results, and I can't see anything wrong inside of it, the motherboard looks good (keep in mind- I didn't take apart anything more then the battery so I haven't seen the whole motherboard). also- my warranty expired.

what can I do? what could be the problem if the whole tests were good? what could've happened?

thanks!
