T520 Function keys don't work (F1 to F12) during POST

[ Edited ]

Hello

 

We have a fleet of T520's that we've applied BIOS upgrades too. Their current versions are 1.26.


It seems after this upgrade, during POST, the Function keys (F1 through F12) won't work. I've tried pressing them during the ThinkPad splash screen to get into the PXE boot menu (F12) and to get into the BIOS setup (F2) to no avail.

 

In fact, NO keys work during the boot up process. If you hold down a key during the start up the system won't even give a stuck key error.

 

The only way we've had success getting into the BIOS is by pulling the CMOS battery out, flushing the power out of the system, and then booting in. We'll then get a BIOS Date/Time error and we're given the option of Skipping by Pressing Enter, or pressing F1 to go into BIOS Setup.

 

This is the only case where we were able to get back into the BIOS. By pulling the CMOS battery.

 

I've installed the Hotkey Integration updates, tried downgrading to different BIOS versions (1.11, 1.21, 1.23, and 1.25) with no luck or success.

 

We've swapped out keyboards with other machines that don't exhibit the problem, and the problem still exists.

 

The function keys work fine once the laptops are in Windows Vista or Windows 7. It's just during POST.

 

If anyone has any suggestions or hotfixes, please let me know!


Thanks

Is this a problem with cold boot, warm boot, or both?

I've seen cases where the F-keys don't work sometimes after warm boot, but they always work after cold boot.

Please go to the following website:

http://support.lenovo.com/en_US/downloads/detail.page?&LegacyDocID=MIGR-68488

 

1.  download Sample Scripts for BIOS Deployment Guide

2.  extract ListAll.vbs

3.  on a machine that has this problem, run a command prompt as admin

4.  "cscript.exe ListAll.vbs > output.txt"

5.  paste the contents of output.txt to the forum

 

Specifically look for the setting called "StartupOptionKeys".  Sounds like your system is set to "Disable".

Re: T520 Function keys don't work (F1 to F12) during POST

The T520 BIOS sucks.  I first booted the machine and got into the Lenovo factory load so I could run the asset info program from Lenovo, winaiapackage.  Everything went fine, then I rebooted and had the machine talk to our FOG server to load it's mac info into the server.  Then I rebooted again and the thing went to pieces.  Pushing the blue ThinkVantage button doesn't give me any choices.  All it does is starts the recovery options.  I don't need the recovery options, I need to boot from the network so I can deploy the correct image.  I never had this problem on the T500's or T510's.  On those models I could just push F1 to get to BIOS or F12 and get the 1 time boot option.  I know Lenovo must have changed things to make this new and improved, but they missed the ball on this one.

yqk,

 

Please see my post in message #4 above.  Is this your personal system or is it a company system under management by your IT department?

yqk,

 

The only other suggestion that I have is to turn the system off (shutdown, not standby or hibernate), turn it back on, and then immediately start pressing the F1 or F12 button repeatedly, at least 2-3 times a second, and just keep pressing it.
