Is the only way to resest/delete the BIOS passwort removing and reprogramming the bios chip? Or is there any other easier method?

Most Elitedesk models the BIOS IC is accessible when the bottom cover is removed. You need to use a suitable SOIC8 clip (like a Pomona 5250) in conjunction with a half decent programmer (I use a SVOD3) to do the dump.
Use RCUnlocker by Rhetorical Cheese to remove the password from the dump, and write it back. Then you just need to reset all security defaults to factory in BIOS setup.
I just did 11 x 430 G4's y'day without disassembly.

Two of the posted requests have a different type of chip W25Q128BV WSON8 , MX25L12805D SOP16

WSON8 huh? Well can't use the clip then. The Elitebooks I've seen with that chip do have pads on the PCB that you can connect with pogo pins.
Don't know what the 640 G3 is like to pull apart, but some Elitebook models are a major PITA to pull apart just to do a BIOS IC. Any suggestions on a half decent Pogo pin clip?
