Hey guys! I've recently found out this amazing forum where people talk and discuss about electronics repairs and i'm actually amazed with everything that here's have to offer.
Oh well, i came here looking for a simple bios file in order to get my main laptop working again, but after a while trying to figure out what the hell was going on, i'm quite concerned that it would be worse than i tought. I was fooling around with Mr. Smokeless's UMAF BIOS mod, looking for a way to enable CSM compatibility and legacy boot on my device.

It's already computrace disabled and all that good stuff, W25Q80V and W25Q128V seem fine. The issue is powering the thing on, the fan will spin for about a half second and if power is kept in, it continues to do so in intervals. If I place the battery in, it will show orange for just a sec, now interestingly, if I place a charger in both the TB port and charging port at the same time it will turn white or charge until completion, how odd, but it won't boot. Any ideas? -

After messing around with bios (reflashing it), removing ssd, wifi, battery, etc, none of helped, I checked 5v and 3.3 coils and to my surprise, multimeter showed both coils hovering around 4V for 5V coil and 2V for 3.3v coil.
Thermal camera did not showed anything hot, but I'm sure something is either going...
