[Request] Unlock Bios 123B for Compal HEL80

Hi,

I have a laptop with Compal HEL80 motherboard with Intel dual core chipset (Bios 123B of 24/08/2007) with Windows 10 Pro 64bit (in attachment).

I recently increasing RAM bringing it to 4GB (previously installed 3GB). The system recognizes installed 4GB but I can use only 3GB (even the bios "counts" 3072 MB) .  How can I use all 4 GB installed?  Can I do this by unlocking hidden options from bios?
