BIOS update for Ideapad 310151KB

I am told via the Lenovo Companion application that there is a BIOS update available for my Ideapad. However, when I go to download it, I get the following screen:


Since mine is NOT a Touch-enabled laptop, can I still install this BIOS update?

Re: BIOS update for Ideapad 310151KB

I went to your drivers download page and found a BIOS update; however, the readme is sending a mixed message as to whether (or not) you can (or should) install this BIOS update:


Flash BIOS update - Flash from Operating System version for ideapad 310-14IKB, 310-15IKB, 310 Touch-15IKB, 510-15IKB

Installation README
Updated Date: 2017-03-07
This package updates the basic input/output system (BIOS) on Lenovo Ideapad 310/510 - 14/15IKB(with Touch)
BIOS, abbreviation of Basic Input Output System, is integrated in ROM chip on main board, which contains the basic input/output program, system configuration information, system startup self-check and pre-setup programs. BIOS provides most basic low-level hardware operations; it is the connection between software and hardware, and interfacing window of hardware and operating system.

Note: Make note of any settings you have changed in the BIOS Configuration Utility. These settings may have to be re-entered after updating the BIOS.

Attention: Do not power off or restart your computer during the BIOS flashing process, which will cause serious damage and improper functioning of your computer.

Print this file so that you can refer to it during the installation.

Although it shows this BIOS update is applicable for your unit (first line highlighted in red), I would not install it unless I get the OK direct from support because your warning message (and the second line highlighted in red) clearly raises a caution flag about compatibility here.


Good luck,

Here is another thread on this topic that has some very detailed discussions:


Ideapad 310-15IKB model 80TV Bios update - 10[64] V.3JCB24WW


At this point, I would say "If it ain't borke, don't try and fix it."
