Re: toshiba p50-b need bios

hello, this is VG20SQG\20CQG MB REV 2.1 motherboard and my device is toshiba satellite l50-b-11u. When I say turn off the computer, the fan continues to run and does not turn off. I think this is from the bios. I have solved such problems with bios before, but I cannot find the bios file. I tried the bios and ec files here but it didn't work. Could you help?
