Y570 bios update\downgrade

[saaasa]

can someone answer my questions about BIOS. Why the BIOS update on LENOVO site only 2.06 why no 2.08. When I bought the laptop it was 2.08! Does a different version influence on the performance in games and in general. Does it Erased the previous version of the BIOS (2.08),if i downgrade to 2.06? Where can I find 2.08?

if the bios version of the file is 2.06 on the download page, it's the latest one.

Yes you are right! But when i bought laptop (i3 2330m...) the BIOS version was 2.08(47CN30WW(2.08)maybe factory bios?? ), why? Can it be manufacturer's fail? Does older version 2.06 reduses the performance versus 2.08? bad english sorry

there are few similar threads about the same issue, the answer was "same versions, just typo issue"

Do i have a problem if i don't rebooting the system before applying the BIOS update and if i install mod bios 2.06 from bios mods before? Does it rewrite this failure mod bios after install current version 2.06 from LENOVO? The current 2.06 have been installed by me without rebooting before. And i didn't notice any problems. Do i have to reinstall it with already rebooting and will it erase any problems? Thanks!

it was about y560 bios and i don't remember where it is.
you need to restart your computer before flashing bios update ,it's important. i don't suggest you to re-flash the same bios.

Why i don't need to re-flash BIOS? Will service center backup\change bios\motherboard in such case?

[yigit]

i can't say anything about it.
