U410 Cannot Update BIOS or Access it through UEFI

I can't get the BIOS to update (to version 65CN99WW, running a much older version). When I run the provided tool the laptop just sits at a black screen and doesn't do anything. Do I have to update to a BIOS in between first? And to get to the BIOS to boot from a flash drive or something, I can't access the UEFI settings option in the advanced Windows settings.

Re: U410 Cannot Update BIOS or Access it through UEFI

Hi a_dunker , 

 

Greetings. 

 

Similar to your issue on this article that you can follow . 

 

To those that are running Windows 8 and not able to access the BIOS, please download the BIOS update from the link below. 

 

BIOS Update for Windows 8 (32-bit, 64-bit), Windows 8.1 (32-bit, 64-bit) - IdeaPad U310, U410

 

  • Fix issue: BIOS and boot menu can't be accessd after windows recovery.
Install the package in Windows
  1.  Restart computer. Press Fn+F2 enter BIOS.
  2. Choose "Configurtion-> BIOS back flash" , set to Enabled.
  3. Choose "Boot-> Boot Mode", set to UEFI. save and exit.
  4. Locate the file 65cn99ww that has been downloaded.
  5. Double click the 65cn99ww For Windows 8, you may run it as administrator by right-clicking on the icon and selecting “Run as administrator”.
  6. Click YES.
  7. System will reboot and flash BIOS. During the process, you are advised not to turn off the computer.
  8. When the update finishes, the computer will automatically reboot for the changes to take effect.
  9. Press Fn+F2 to enter BIOS menu, load default setting-> save and exit.
  10. Please reboot the system again.

 

You can also try turning off the PC and using the Novo button (one key rescue button left side item1 page 4)  to turn back on. This would offer the BIOS setup option from the Novo menu , Choose "Configurtion-> BIOS back flash" , set to Enabled. Choose "Boot-> Boot Mode", set to UEFI. save and exit. 

 

Update us how it goes. 

 

 

Regards

Part of the problem is I cannot enter the BIOS at all. It boots straight into Windows. Similar with the novo key, if I use it to boot the computer the selection screen comes up, but no matter what I choose it boots into Windows.

Hi a_dunker , 

 

How if you just remove the harddrive .

Then access the BIOS and change settings to defaults and maybe consider disable secure boot .
