Medion Akoya E6435 no power
So after not powering up a Medion Akoya E6435 for several months, I found it no longer powers up at all when I tried to turn it on today. I did some basic fixes and failed to make any progress. As I removed the keyboard and felt around the parts of the motherboard that were visible, I could sense some heat coming from somewhere, it was very faint.
This prompted me to take a closer look as experience has told me a heating board is a bad sign. I disassembled the laptop completely and removed the motherboard. I then hooked up the charger and turned the motherboard on the opposite side where I felt the heat coming from. I touched the top of a chip and ouch, the heat was immense. It gets rapidly hot the moment the charger goes into the charging port.
Once I take it out, the heat subsides. I don't have to press the power button at all. It isn't even connected at this point. Pretty much nothing but the CPU and heatsink is attached to the motherboard.
So now I at least know the motherboard has some sort of fault. I cannot identify what the chip does and Google isn't helping. This is rather annoying as I'd like to try and fix it. The chip has markings “3F = 3L 80N” on it. Does anyone know what that is responsible for?
I tried to see if there were any replacement motherboards on sale, but unfortunately I couldn't find any for the E6435 model. Does anyone here happen to know if any other motherboards would be compatible with the laptop chassis? I know it's a long shot, but I thought I'd ask.
It’s the one marked “3F = 3L 80N”.
As for the motherboard number, I’m finding it difficult to locate.
I’ve screenshotted the numbers I see. There’s a sticker on the CPU fan, but that’s likely the model of the fan, so I didn’t take the screenshot.

Post an image of the "chip" in question as that may help to identify it.

Also what is the "board number" of the motherboard? (printed on the motherboard itself), include any Rev. numbers as well.
Sometimes the schematics for the motherboard can be found by searching for the board make and model number. Do not be surprised that the board is not made by the laptop manufacturer but is made by a specialist board manufacturer to order to the specifications of the laptop manufacturer
@jayeff I've added some screenshots to the main post.
