I have a Y510P that has the annoying habit of slightly oscillating the fan speed when it's in a low-power-using state. It goes slightly louder for one second, then slightly quieter for one second, then slightly louder for one second, and so on. Other solutions haven't worked; Speedfan has no access to the fans and Lenovo's own fan speed control driver is useless. I was hoping I'd be able to control this in the extended BIOS; does anyone know if this is the case? Ideally I'd just tell the fan to never go below the second-to-lowest speed so that it doesn't oscillate any more but I'd like to know if this is possible before doing something that would potentially brick my machine. (My apologies for posting this in two threads, I wasn't sure if the other post had gone through or not.)

Hi everyone, I was trying to find a way to unlock the BIOS on my Y510P (no wonder it's so barebones) because of the possibility that I might find fan speed controls there. My laptop has the annoying habit of slightly oscillating the fan speed when it's in a low-power-using state. It goes slightly louder for one second, then slightly quieter for one second, then slightly louder for one second, and so on. Other solutions haven't worked; Speedfan has no access to the fans and Lenovo's own fan speed control driver fails to even start up. I was hoping I'd be able to control this in the extended BIOS; does anyone know if this is the case? An unlocked BIOS would be nice regardless but I would also appreciate some advance information before I try something that potentially bricks my machine.
