t500 bios version problem

Hi, everybody! I update my bios with bios update utility to 3.23 version and my problems began. First my t500 began to enter sleep mode randomly, after check in event viewer it`s ahci code 13. Second problem is very strange, the display dims and the brightness go lower, the laptop is in the ac and battery is ok, after 4-5 seconds it goes to max brightness, may be power plans go wrong, i dont know. Third problem is blue screens and after check the problem is with wifi card. With previos version of bios i dont have any problems. My question is how to downgrade the bios version or is there newer than 3.23? My bios version is 3.23 (6fet93ww)
