ACPI problem...

Hi friends,

I am using Lenovo y500 776136q model laptop. I found some problems with my laptop, Some compatibility issue with linux. Problem is My laptop’s keyboard and mouse won’t work when I am booting to linux from “computer off state”. But When I am booting after restarting from windows it works fine. What I am thinking is, the problem is with ACPI thermal zone and Bios. ie ACPI works fine after Laptop reaches a particular temperature.Windows not shows any problem. Can anyone tell me a fix for this problem. I have tried many Linux distros…But same problem…
