S540 Touchpad not working

The Touchpad on a cliënts S540 is not working anymore. It started with complaints about non-responsiveness when the laptop woke from sleep (after being closed and opened).

I've tried to install the latest drivers (18.0.7.99) from the Lenovo website but that didn't give a solution.

 

The laptop is running Windows 7 Professional 64bit.

Hi Niels84,

 

Welcome to Lenovo Community!

 

As per the query we understood that you are facing issues with Touchpad not working after resuming from sleep mode on your ThinkPad S540.

 

Please check with updating the touchpad firmware from the below link.

 

http://support.lenovo.com/us/en/products/laptops-and-netbooks/thinkpad-s-series-laptops/thinkpad-s54...

 

Hope this helps.

 

Best regards,

Hemanth Kumar

Re: S540 Touchpad not working

Thanks for the reply Hemanth.

I tried to install the firmware from your link but I either got a message that the driver was not found/installed or some weird error message with selectors. I tried to install the drivers again but that didn't help.

 

The second thing I tried was to reinstall the machine from the recovery partition but that didn't work out either. Now the keyboard drops out after a few seconds of logging into Windows and the touchpad/trackpoint aren't resposive at all.

Hi Hemanth,

 

I've tried your suggestion and it didn't work, both keyboard and touchpad are still unresponsive.

 

I also tried to boot from a Linux Live memorystick. The touchpad and trackpoint didn't work within this boot but the keyboard did work. In a weird way though because every key was registered as multiple strokes. For example if I press F it registers as FFFFFFFFFFFFFFF

Hi kajjak33

 

Just to have more information, can you please share the full model number of your machine?

 

If you also can check the hardwareID (from the Windows Device manager) of the touchpad and share it will be great to document more about this issue on the forum.

Re: S540 Touchpad not working

For what it's worth: The unit I had was returned for repairs because it was a hardware problem.

And we're back...
