Thanks it worked !!! BTW is this BIOS valid for all Ideapad M490s or just my own as mentioned in the readme?
Serg008 - I saw that you had mentioned it in a previous post but I wasn't sure how to proceed with that utility. I will give that a shot. Thanks. Edit - works perfectly.
Serg008, can advanced user perform bios modification if he has such programmer? P.S. Oh, God! I hate Lenovo and HP! Evil companies that make their consumers suffer!!! I'm stuck with awful Broadcom 4313 chip inside my beautiful notebook. It gets me max 72 mbit of speed in a world where 300 is reality!!! Furthermore, it freezes in 33% of boots and reboot doesn't help. Only power off and power on. Never, never Lenovo or HP or any whitelist adopters!!!
