C730-19ICO BIOS Update Questions

Hello ! A month ago I bought a C730-19ICO (8700K / GTX 1060). The ventilators are a bit loud, I have some static noise coming out of the front audio jack (back is ok) and it is clearly overpriced in Europe but I'm sort of happy with it. My previous computer was an own built but this time I wanted an easy upgrade without the potential trouble. I'm very happy with the speed (gaming is not the main purpose) and soft things as Dolby (great sound !) and the configurable LEDs.

 

When I bought it I updated all the drivers to the most recent versions and the BIOS to version 1.22 (O3NKT22A, May 2019). A few days ago Lenovo has published a BIOS update on their website to O3NKT23A (1.23) and while I don't see any need to update yet as the system works well and without any problems I would like my machine to always have the latest BIOS version. I have updated the BIOS once sucessfully on this machine to 1.22 but I'm generally extremely afraid when doing so as if it goes wrong the computer will not start or in the worst case the motherboard will be "bricked".

 

Here my questions for the C730 for the case I decide to proceed with the BIOS update to 1.23 and the rare case that the process goes wrong:

 

- Is there an option to restore the original BIOS (e.g. key combination at start as in HP computers) or an "emergency" BIOS ?

- Is there some other solution as moving a CMOS jumper to update the BIOS from a USB stick ?

- Could the motherboard (BIOS chip) really be damaged i.e. made unusable ?

- And last, is there a handbook/manual for the motherboard or the steps above ? That would answer all the above questions but Lenovo does not offer a lot of help in regards to technical specifications.

 

Thansk a lot ! Miguel

Re: C730-19ICO BIOS Update Questions

Hi MiguelC730,

 

Welcome to the Community Forums.

 

The readme. txt file would offer some information for you that you can review.

 

--CONTENTS--
 1 - Installation Instructions
 2 - Flash under Operating System
 3 - Flash Program Options
 4 - Flashing Back to an Older Level of BIOS
 5 - Delaying Reboot in BIOS Update
 6 - AMIDEWIN - AMI SMBIOS Editor for Windows

 Personally, if you are ok with the current BIOS version (O3NKT22Aalong with its performance then there maybe no need to change it.

 

There are some instances that failed BIOS update may brick the board like sudden lost of power during the process or others are not happy with the changes made.

 

I hope this helps answer your query.

 

Regards

Re: C730-19ICO BIOS Update Questions

Thank you ! I read the file carefully but it does not give any hint on what to do if something goes wrong. For example some newer HP computers have an "emergency" BIOS that you activate at start with Fn+B that will allow the motherboard to try to update the BIOS from a stick in case something goes wrong during the update. I was looking for some solution in this direction.
