@smdflea has very good experience in fixing bios and hp virgin bios should work. You said the laptop lying for long time. You got display before flashing bios??

Re: hp probook 455 g4 dump file

yes , it works fine , the chip model is 25B128CSIG, when i use "detect" on ch431a programmer shows memory type :GD25Q128 , using this config i could read the chip , erase , and write, but i get verifying problem "chip main memory with the contents are in disagreement" , now it gives the same led flashing after restoring the original dump file which i backed up, anyway to fix that?

Oh, I'm sorry.. the problem is that when it turns on, the screen remains black, and the fan from the processor starts to whine more and more.
