[REQUEST] Lenovo Y50-70 (9ECNxxWW) Whitelist Removal

[1vanK]

Hi,
I need some help...
So, I stack together laptop from old parts, most of them are from Toshiba satellite L350-147 (LCD, housing)...but motherboard is from Toshiba l300-17o. Visible difference is in screen size, l300 is 15", and L350 is 17", and MBOs are exactly the same (at least regarding dimensions, connectors....), so the Frankenstein laptop (after replacing NEC/TOKIN capacitor on MBO) starts to work (great, right?). The only bad thing is that the 105key keyboard acts like it is 85 key keyboard... A friend of my said "there is a numb-lock option in BIOS", so i have search for it, but there is no such option, I have insyde BIOS 1.5 version (MBO Part number: PSLB0E-06U015G3), I was looking and it seams to be the last update...and no numb-lock option in BIOS... So I have tried to turn numpad with Fn+F11, numlock led turns on but numeric pad is not working, and I have found that numbers are allocated across leathers [m j k l u i o 7 8 9 ] and not over the numpad ...

So, the big question is, is it possible to update l300 with modded BIOS where 105key keyboard would function in proper way?
If answer is "yes" please direct me in what to search for, and what to learn more to make keyboard work as expected.

Thank You in advance for answers and feedback.
