Lenovo y50 keyboard has completely stopped working

Hello

 

My Lenovo y50 keyboard has completely stopped working. Every single key will not respond.

The only thing that works is the back light. No fluids have been split on the keyboard recently!

(6 months ago a bit of water but it was ok).

 

A few things I have tried

 

1) plugging in a external keyboard - it works

2) reinstalling the keyboard drivers - no

3) Using a live version of Ubuntu - no

 

So any guesses what could be wrong? Loose cable? Hardware failure?

 

But most important how do I fix this?

 

thanks in advance!

Hi fobstaa ,

 

Welcome to the Community Forums.

 

I am also expecting that the keyboard fails to respond in the BIOS too. If cleanup and checking for corroded contacts still have the same issue then replacement of the internal keyboard should be considered.

 

It is probable that the issue is hardware in nature since using different OS shows the same failure but using external keyboard is ok. This can be verified if persistent in the BIOS since it works on basic I/O firmware interface only.

 

Here is the guideline on looking for part number specific to your machine. The support site have documentation tab for the hardware manual as reference to replacement steps.

 

I hope this helps answer your query.

 

Regards

Hi Spidey101

 

Thanks for the quick reply

 

Yes I can only access the bios via the external keyboard.

 

As you suggest, I will have a go at checking for corroded contacts and then if a clean doesn't fix it I will order a new keyboard.

 

I will report back

 

thanks again for your help
