Lenovo Yoga 500-15IBD OLD BIOS File

Hi, I have a problem with the keyboard on my Yoga 500 where some of the keys don't work as they should.

It's not a Windows issue and I could do with trying an older version of BIOS.

Can anyone provide the previous version BIOS file to BDCN63WW.cap for a Yoga 500-15IBD

Thanks

Andy

Welcome to the Lenovo Community AndCam !

 

Which keys do not work?  Try using a USB keyboard to see if the problem is the same.  If a USB keyboard works without any problems then you most likely have a hardware issue with the keyboard. 

 

As for the BIOS flash, they shouldn't be done needlessly since there is always an element of risk when flashing the BIOS.  Even in the most perfect environment a BIOS flash can go wrong and cause more problems than what you are trying to solve.  In other words you have a keyboard problem now with a working computer...... a bad BIOS flash, you could have a dead machine.

Re: Lenovo Yoga 500-15IBD OLD BIOS File

Hi, Thanks for the advice. My keyboard problem is a bit of a weird one.

It all works fine if I use a US keyboard.

ut if I use the laptop keyboard, I have problems. Just using lower case letters I get all the letters of the alphabet...

abcdefghijklmnopqrstuvwxyz

If I use the lft shift to get capitals, I get....

ACDEFGHIJKLMOPQRSUVWXZ (missing the capital b, n, t and y)

If I use the right shift, I get....

ADEFGHIJKLOPQRSTUWY (missing th b, c, m, n, v and x)

If I use Caps Lock, all the leters work Ok...

ABCDEFGHIJKLMNOPQRSTUVWXYZ

I can type a "/" but not a "question mark".

Do you still think this is a hardware issue"question mark"

hanks Andy

Just to rule out any hardware conflicts, try this......

 

1. Shut down Windows and unplug the charger / adapter.
2. Press and hold the Power Button for 15 seconds.
3. Plug in the charger / adapter and power up the system to see if the problem was resolved.

 

If that didn't resolve the problem what I would next try is go into Windows Device Manager and select the keyboard by right clicking on it.  Then choose uninstall from the menu.  Windows will then uninstall the keyboard.  Reboot the computer and on boot up Windows will reinstall the keyboard.  By reinstalling should resolve any driver conflicts. 

 

If that doesn't work then I would recommend you contact Lenovo Support for additional warranty assistance for a keyboard hardware issue.

I tried the steps as suggested but it dd not resolve the problem.

I know it is not a Windows problem as I tried a Linux boot CD and still get the same issues.

I will raise it with Lenovo Support for further assistance.

Thanks

This problem was resolved by sending the laptop off for repair under warranty.

Very quick turn around and had the keyborad replaced.
