Hello!
I modified laptop - Lenovo B50-30 with Celeron N2840.
Belive or not but this laptop comes WITHOUT ventilation slots and WITHOUT fan. There is only Ship like this on CPU: http://pl.tinypic.com/r/4gke1f/8
But i found power connector for fan on mainboard.
So i modified laptop: http://i59.tinypic.com/delpp0.jpg added fan and made ventilation slots: http://i57.tinypic.com/eqnmhc.jpg
***
Fan starts when i turn laptop on.
Fan starts when i run Lenovo dust removal.
But fan does not start when i run benchmark and CPU temperature goes up.
I installed SpeedFan - does not work.
I installed TPFanControl - does not work.
But TPFanControl shows something like this in status: Fan: 0x40 / Switch: 97°C ( 0; 0; 0; 0; 0; 0; 0; 0; 97; 0; 0; 12; )
I belive that fan controller is turned off in BIOS or locked on 97°C.

BIOS/UEFI:

Am i right? Is there a way to change fan behaviour? How to unlock advanced options in bios? Is there any fan control option?
