Re: G700 f4 problem

2014-01-20, 16:49 PM

I applied the bios patch to fix the F4 key bug for our G700.

 

The F4 bug is now fixed but we are encountering other problems with this system, like Windows To Go usb drives no longer booting ('UNMOUNTABLE_BOOT_VOLUME' error).

 

This was working fine before the bios update.

 

I have tried all possible bios configurations, but no way to have usb drives boot again.

 

Could you please provide an .exe to revert back to the original bios?

 

Thanks!

You are absolutely right. I made the same experience, that it seems to be impossible to boot from USB now with the new BIOS.
At the moment I have no idea, how to return to the old original BIOS

to gibonus,
I have no idea, which program turns of your computer under which circumstances.
My procedure in such situations would be:
Wait until all lamps are off - the battery lamp may stay on - and until the machine is completely quiet. Wait additional 20 seconds. In case there happens nothing the computer will not turn on by itself. One exception: Some computers might turn on by itself in case there is a planned start (e.g. for updates).
Anyway you can turn on a machine which was quiet for 20 seconds manually.
Wait 0 seconds and after that it will not turn on

new experience:

A USB-Stick made by Seagate's DiskWizard will boot also on the new BIOS. MBR of this USB-Stick is different from that what was made by Windows 8. Type of USB-Stick was identical in both cases.

 

Conclusion: It seems to depend on type of MBR if an USB-Drive will boot on the new BIOS.

CLEO,

 

THANKS FOR YOUR RESPONSE.

 

I CALLED THE SERVICE CENTER AT THE ADDRESS LISTED BELOW.  THEY REFUSE TO WORK ON THE G700 MODELS AND SAY I HAVE TO MAIL IT IN SOMEWHERE.  I CANNOT AFFORD TO BE WITHOUT THIS WORK COMPUTER.  I BOUGHT THIS COMPUTER FROM LENOVO ONLINE.  PLEASE EITHER LET ME KNOW WHERE I CAN TAKE THIS TO HAVE THIS WARRANTY WORK DONE OR PROVIDE INSTRUCTIONS FOR BEING REIMBURSED FOR THE FULL PURCHASE PRICE SO I CAN BUY ANOTHER BRAND OF COMPUTER WHICH INCLUDES WARRANTY SERVICE.  THIS LENOVO F4 PROBLEM COMBINED WITH THE LACK OF SERVICE IS UNBELIEVABLE.

COFFEEECUP,

The machine has to be with service engineer to flash the BIOS.
Anyway, I sent a PM to you. Could you check?

Good news is that I have been trying to push the backend team to make this BIOS available in Lenovo support site for public download. They should be up soon. I'll share the link with you later.

Cheers,
Cleo
