L440 Touchpad stops working

Dear all,

since almost 2 years I am pretty happy with my L440.

But lately, I often have problems with the touchpad becaue it suddenly stops working,

no mouse moving, no touchpad-based clicking. 

The trackpointer still works and also the hardware buttons for left and right clicking are still working.

 

However, depending on the task i prefer either trackpad or touchpad.

 

I already changed the sensitivity for palm checking but no effect. 

 

Any ideas?

 

Thanks in advance.

Re: L440 Touchpad stops working

Thank you. I was using the lenovo System Updater to ensure an up-to-date system. But with your link i noticed that System Updater seems not to provide always the most recent updates.

Thus, I will give it a try

 

EDIT:

Meanwhile i get "an error occurred while loading resource dll". Seems it is related to the power manager.

Hi Bleu,

 

We are sorry to hear that  touchpad issue has been not resolved.

 

You could also use the System Restore feature to get your computer back the time when it worked.

 

Note: Please take the data backup.

 

Hope this helps. Do post back if any further details required.

 

Best Regards,

Poojitha.

Re: L440 Touchpad stops working

Pretty disappointing solution to simply restore a backup as this problem might occur at any time again. Should I restore then again including all overhead like reinstalling applications?
