You will need an SPI bios programmer to make a backup of the chip.The chip is in a WSON8 package,so you will need to desolder it first ,then put it into a WSON8 adapter or alternatively use a WSON8 pogo adapter (unreliable YMMV) .Then read the chip a few times,check to make sure you`ve made a good backup, then post it here inside a zip or rar attachment and also post the laptop serial number.

I tried unlocking the 840 G4 bios because it was password protected. He no picture since then! I uploaded both the original dump and the unlocked file! Please help!
Read the rules before posting please! You must post the laptop serial number !
Additionally unlocking method for this laptop model is available at BIOS guides, methods, resources and tools thread!
