G700: Pressing F4 button closes a window unexpectedly

Question

I have a problem with F4 button. I don't like to use hotkeys without FN therefore I turned off hotkeys in BIOS.

 

Now I get a new problem that the F4 button is working as ALT + F4. It means that any action with the F4 button will result in closing a window.

Answer

Update to version 7ACN89WW (v3.07) or above should address this F4 key issue.

 

Previously we advised users to get assistance from nearby service centre for flashing the new BIOS due to concern about any issue may arise from flashing BIOS by users.

 

Now, the BIOS can be found in our support site.

 

Download here: 7ACN89WW (v3.07)

 

Summary of changes:

Modified: 

1. Modify hotkey F4 function for new spec.

 

Fixed: 
1. Fixed no sync physical boot option to invoke the boot order fault.

Great solution.  Does this update work on the keyboard bios for the Z710?

arndwg,

 

Z710 will have its own BIOS. Do not flash wrongly!
