Legion Y520-15IKBN UPDATE 4KCN45WW PROBLEM

2019-02-15, 2:57 AM

Hi everyone,

I'm having a problem about the BIOS update. When I lunch the program of "Lenovo Vantage" and I try to update the bios, it crashes. After the program tells me to restart the laptop, but if i try the update again it fails. I post also a picture about the problem because I don't know what I have to do and I hope you can help me. Also, I found a solution of another similar post and  I tried it  going on Bios Setup and I did two commands : F9 for default settings and F10 to save them and exit from the BIOS menu. Consequence? Nothing changed.

I hope you can help me because I haven't got other solutions. Thanks if you read it and if you try to help me.

Greetings and welcome new Lenovo forum user from Italy,

 

The BIOS Version 4KCN45WW can be found on the Y520 Lenovo Support page and suggest giving that a try getting flashed with Vantage out of the way.

Greetings Duke3dnukem,

 

Do not rely on the Vantage application and would not delay anymore seven months is long enough.

 

 
Downloading the package
  1. Click the file link to download the file from the web page.
  2. When prompted, select a drive and directory in which to save the downloaded file.
Install the package in Windows
  1. Locate the file 4kcn45ww.exe that has been downloaded.
  2. Double click the 4kcn45ww.exe icon.
  3. Follow wizard UI by making sure what BIOS to flash and flash on what platform.
  4. Finally, press Install & Finish to start flashing. During the process, you are advised not to turn off the computer.
  5. When the update finishes, the computer will automatically reboot for the changes to take effect.

Thanks for the info!!  I've have been getting the same crash after trying to install the version 4KCN45WW  bios with Lenovo Vantage since last year.  I had given up, but kept getting notification to update the bios.  Found your postand and after downloading as instructed, I with much trepidation pushed the install on the exe file and kept my fingers crossed since I have read that a wrong bios update can turn computer into a dead brick.  However all worked well and now Vantage says system is up to date.

Hi, I have the exact same problem, but I can!t update the BIOS thru the downloaded .exe file. It says that "The version of ROM file is the same as that od BIOS." What can I do with that?
