L540 touchpad maintenance?

2019-05-16, 2:26 AM

There doesn't seem to be a forum for L-series notebooks, but this one comes closest I guess.

I bought an L540 at an internet auction whose touchpad's "mouse buttons" don't work. Compared to the very similar touchpad of the E540 that I also own, it seems to be pushed in.

The hardware maintenance manual doesn't contain information about the touchpad.

 

Are there instructions how to remove or generally service the L540 touchpad? Could I replace it with the E540 touchpad (the E540's screen as stopped working, so that I can't use it as a laptop anymore)?

 

EDIT: Apart from the "mouse buttons", the touchpad works: I can move the mouse pointer, and I can generate mouse clicks by tapping on it.

 

 

Moderator comment: Moved your thread to L-series ThinkPads.

Hi berndbausch, Thanks for reaching out. We found the manual that will teach you how to disassemble the touchpad you can find it by clicking on this link (Page 96) https://download.lenovo.com/ibmdl/pub/pc/pccbbs/mobiles_pdf/l440_l540_hmm_en_sp40a26004_04.pdf?CID=ww:lenovosocial:20x9m6.

As for replacing the touchpad, the part number for the Keyboard bezel with touchpad for the L540 is 01HX011 while for the E540 04X4976. You can test it but there is a high chance that it will not be compatible.

Thanks much, Jack, for the pointers.

 

For now I am happy with my "new" L540; I can live with the partially functioning touchpad, but will have another look at it after the current projects I am working on.
