hy to all,

excuse me for my English. In first post the file Lenovo Y580 - Y480 BIOS v8.01 (5DCN90WW) - Mod.zip((8.01) has extension *.ROM and the another one Lenovo Y580 - Y480 BIOS v8.00 (5DCN90WW) - Mod.zip(8.00) has extension *.BIN. i first tried 8.00 which is BIN file it worked fine but missed all board serial number. when i tried 8.01 ROM file with fpt and BIOS-fix all procedure you mention earlier. my laptop got bricked. pleas guide me and explain to me difference extension matter or not. min original version is 8.01. now i recovered min laptop.

If you looked back a few pages you would have seen that I posted the EXACT same thing. It is a driver problem, not a BIOS problem; and it still does not work with the new drivers.

Backlight for what? You still haven't specified. If the volume functions don't work also then you need to replace your keyboard.

You are the first person with a v9 of anything on this thread.

thanks for reply..

function button working, with volume, brightnes etc except backlight. backlight mean when i press Fn+space button all keyboard glow in lenovo y580. and also there is separate volume mute button not working. backlight and mute button stop working when i flash wrong version 5DCN96WW v9.01... after recover back to original bios 5DCN90WW v8.01. but EC version could,nt back to original. i think because of the difference between ec and bios version these button not working.

i am just asking that how can i fix this problem. and if you ask than i will tell the whole story.

additional information... UEFI setting not working. now using legacy for hard drive to boot window.

Bios version 5DCN90WW v8.01

EC version 5DCN96WW v9.01

lenovo y580

backlights and volume buttons not working maybe because of NVRAM not clear during roll back from wrong bios version. any help would be appreciate

Ummmmm....

To control the display backlighting you press the Orange Fn key and either the Up or Down Arrow Keys. If you have a non-factory display you only get Minimum or Maximum brightness.

For the keyboard backlight you press Fn and the Space bar. The service techs may not have reconnected all of the ribbon cables so removing the keyboard and double checking that they are indeed connected could fix it. I have no clue how old your laptop (or keyboard) is so the backlights could have died if they do not turn on.

thanx for reply
