Lenovo BIOS Update - 10 [64] - 4WCN47WW

2020-10-23, 4:48 AM

I'm here to just help if someone who's not deep technical or a normal person who'll face issues after this new bios update.

 

New Lenovo BIOS Update 10 [64] - 4WCN47WW has been released on 16-10-2020 after updating the firmware has changed my OS boot mode from Legacy Support to UEFI mode hence after the firware update completed my OS was not booting and I just thought to see my bios mode and it was changed to UEFI, when I changed it back to Legacy support everything was all right and back into my beautiful screen again!!.

If anyone has been updated or some one got the prompt to update this firmware, just keep in mind that you may face the same issue and just change your boot mode accordingly and you'll be back to your system.

 

Thanks

Best regards

Hello Ayushi,

Glad if I can help you this out!!, Please shut down your Laptop and and Power on and immidiately press on F2 which will take you to bios mode and from bios mode go into boot options and check the boot mode if it's UEFI mode change it to Legacy Support and save the settings and exit from BIOS mode.

hope this works for you.

ThanksBest regards

Hello!

I know that's a common issue but my laptop ideapad 320-17IKB is experiencing high fan noise(or coil whine) while the cpu usage AND temperature is low ...Also I have tried several apps that check fan speed but all of them are not able to detect the CPU fan.... Thank you in advance for your interest, I wish you a happy new year!
