G580 20157 Bios Downgrade

Hello,

when i installed latest bios update on my lenovo g580 20157 62CN97WW

when i enter bios i see g480 instead of g580 also no Serial Number

 

on windows 10 CPU runs too hot

also bad graphics performance (intel hd4000 + 610m)

 

is there any way to roll back to 62CN40WW?

 

tried direct install from exe but i got ERROR 233 - Only secure capsule is allowed on a SecureFlash system!

Did you try resetting the BIOS? You can do this by powering off the notebook, removing the main battery pack and disconnecting the AC adapter. Once this has been accomplished - press and hold the notebook power button for more than 30 seconds, then release. Reinstall battery, reconnect power adapter and turn on the notebook normally and check to see if the problem still exists.

Good luck.

I would suggest contacting Lenovo Support via phone - they may have a older BIOS available for you to install.

Good lucl!

On the support tab there is a section near the bottom for links to other features / areas on the site.  You shoud see one for "Phone Numbers" and it should take you to a page where you can select your region and find a number to call in the drop down listing...

 

Link to phone number site (USA)...

 

This shows the US of A listings when I view the page.

 

Good luck.
