Thanks so much for your help, sir. It's working. The SN is empty, so I will try to add its own SN. Thanks, and I appreciate it.

Hi, I have a hp probook 450 g5 i5 8th.
Initially when I plugged in the power the notebook turns on by itself and after a few seconds the fan, I noticed that the kbc nuvoton was overheating and I ordered a new one from china.
now after changing the new kbc, when I plug it in the screen flashes and when I flash various bios it almost always changes behavior.
Important thing, when I plug in the power, the blue light appears for a second and then goes off, the battery is charged.
I attach my original dump to clean

check if you soldered all the KBC pins well...

it's all soldered well, go over them one by one.
I bought the chip on aliexpress asking to program it for the card in question.
Has the chip been reprogrammed? or if it reprograms itself with the 16mb bios file
There is a difference between one chip and another, with the old one I tried to reprogram some bios but it didn't do anything, only the fan at maximum, this one instead tries to start.

So, I tried to put a VGA cable but nothing, then out of curiosity I put a USB stick and the result is excellent, it started with errors though, is it possible to clean the bios file? so that I load my original?
