Default Help please HP Zbook 15 G3

I was trying to remove a bios password, I removed these chips and read the data from them and unlocked them via the awesome tool on the forum but upon soldering them back now my darn laptop wont switch on and the power button flashes and also the charging port is illuminated

I likely messed something up, am using a tl866 programmer, also could anyone be so kind as to show an image of bios chip orentation for this model incase I made a booboo

Kind Regards

Paul

Appreciate that, I've also tried that to no avail, is it possible my reads were bad.

Would it be ok to flash a bios from the net as I have possibly contaminated the bios.

Thanks for your time peste
