HP Laptop for parts / needs unlocked BIOS chip (Bengeo SG14)

Laptop but note:
- NO Memory (DDR4 needed)
- NO Hard drive (SSD)
- BIOS locked by password (not known)

So for parts only (it does work when it has the above) and needs a new BIOS chip. Only recommended if you know what you're doing!

Laptop is a HP EliteBook 840 G4.
