Which is the original touchpad on the T440/540/W540? There are 3 version of the click-pad

2019-12-15, 18:54 PM

Hello and a good day

I want to replace my click-pad on my W540 casue it got all mushy on the corners when pressing, but I have found 3 different versions of the same click-pad, can someone help on which of them is the best version?

 

My W540 has the first one in the picture, my T540p came with the second one in the picture, but I dont know if they werent replaced prior to me buying the laptops.

 

Could anyone help with which might be the best one, or the genuine one that was mounted from the factory on these laptops?

 

Thank you a lot for your time and help

 

Cheers, Criss

Welcome to the forums.  If you want to look up the original parts that came with your laptop you can go to parts lookup.  Dont post your serial number online.  However if you input at the below site it should provide you part numbers for your laptop as it was shipped from factory.

There are always multiple suppliers of the same part and each supplier would have its own FRU.  They are all "plug compatible".

Thank you for the info guys, well I was curious which of the designs was the best, or which one shipped from the factory but I guess I will order the first and the second one and see the difference.

Thanks again

Hi,

 

If you follow my post it tells you what to do to find out how it was shipped from factory.  You just need your serial number.

I have checked with my serial but on the As-Built page and comodity type it does not list the touchpad, even checking the parts list for the T540p does not list the touchpad, it only lists the Palmrest as a whole, which I presume it includes the touchpad

The W540 trackpad has to have been 'the' worse design. I replaced mine with an after market type similar to the W540. There should be a thread somewhere on the forum about the issue and the registry patch to recognize the keys. I used an Eathtek p/n 4328334041, the driver needed is v19.0.12.61 gggr05ww.exe. Most likely if you search those terms, you'll find all the help you need.

Reg Patch: [HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\SynTP\Parameters]

"ExtraCapabilities7Add"=dword:00010000

"ExtraCapabilities7Mask"=dword:ffffffff
