Hola,
I'm currently installing Windows10 on a Positivo Ultra S4000 laptop for a friend and was looking for a newer BIOS.
Or perhaps a BIOS from a re-branded laptop with the same motherboard.
I would also like to know if it's possible to solder a SIM-card slot on the open space on the motherboard and if it's possible to do a cpu upgrade.
I'm not a certified technician but i am interested in electronics and like to take them apart / repair them.
So, that's who i am and why i'm here.
