Hi ! Peste

Actually I just have a password screen, when I miss the password 3 times it shows no code but just a message telling that I can shutdown or restart my computer.

I hope it's what you were asking, if it's not I'm sorry

you need an SPI programmer..here is a video as an example...https://www.youtube.com/watch?v=DWWigscuQDY

I salute the tech giants in the house. Please i wish to find out, if i allow my programmer auto detect my BIOS chip and gives it a name that doesn't match what's written on the chip, could this affect the functionality of the chip when i reflash with the backed up bin file?

is the chip in the programmer's database??? choose the chip manually..if it is not in the database, you can choose a similar chip..nothing happens with the chip..

I tried this sir after put the charger the caps indicator light turn on then off after 2 to 3 seconds, then i press power button no response not turning on

Flash all the original files of the device and take a screenshot to show me. I looked at your main bios file, it has no password.

the best thing is to remove the chip from the board, remove it with a blower, there are adapters for these chips, search in the software database and see which ones accept this chip..

These are the only thing I have look at the image.


That's why I'd ask if jumpering the pinouts directly will be also work? I'm afraid to damage the BIOS chip if I overheated the chip with hotair workingstation/blower. We are far from suppliers and other technicians if I damage the chip I can't find a replacement.

I just want to ask if is it fine to read/dump bios without removing the bios from the motherboard? Like resoldering pinouts using jumper(magnetic) wire to programmer.
I am planning to reset or remove the bios admin password of HP 640 G9. The bios chip of this laptop is flat unlike other units that has spider pins and this I my first time repairing hp elitebooks bios.
I hope someone provided me a clear answer, I also would like to know what programmer is compatible for hp elitebook 640 G9 to read&write?
