Yoga 460, Ribbon cable trackpad to mainboard

[cfds]

Hello all,

I have recently bought a cheap yoga 460 in pieces and are slowly rebuilding it in a working laptop.
It was missing all the goodies like SSD, RAM and even the touchscreen. SSD and RAM I had and the touchscreen assy I found very cheap.

Now I am looking for the touchpad ribbon cable connecting the touchpad to the mainboard. Seems difficult to find as the Y460 was not the most popular laptop around.

If someone has a yoga 460 and has the bottom cover removed, it would help me a lot if you could take note of the number so that I can do a more focused search on the internet.
I know it has 12 contact points and should be roughly 12 cm long...

Thanks for your help.

Cheers,

Yves

Looks like P40 and Yoga14 and Yoga460 all use the same parts.
The frubom has these two touchpads (but no mention of a cable):
00JT977 N CS15S_3+2BCP,MYLR,BLK,CHY
00JT978 N CS15S_3+2BCP,MYLR,SIL,CHY

Here's a picture of the back of the palmrest: https://www.ebay.ie/itm/384261948409
Looks like it's quite a long (flat) cable from touchpad to mobo.

Looking on eBay for: lenovo touchpad cable these look promising:

Since most of the newer touchpads all look the same, I wouldn't be surprised if all their cables also all have the same connectors (but different cable lengths).

Thanks RBS...
The ebay listing with the palmrest I found yesterday and I took a screenshot in the hope I could read the number on the ribbon cable...
I also realized that the Y460/Y14 and P40 are basically the same machines.

As for the cable you found on ebay, the last only has 6 contacts and the other 2 ones I can not see how many contacts they have, looking at my touchpad it has 12 contacts...

"Since most of the newer touchpads all look the same, I wouldn't be surprised if all their cables also all have the same connectors (but different cable lengths)" I agree that's why I ordered the following cable from ebay yesterday...

Short update, the yoga 460 is alive...
The cheap 2nd hand display is working perfectly - stylus and touch all good.
Battery from 2017 with 25 cycles has nearly its full potential which is a testimony of the quality used compared to the poor quality batteries used in the newer Yoga 910 and the Yoga 930 which I am currently using - I am now running the 3rd battery on a laptop from 2019.
Still waiting for the ribbon cable to arrive so touch-pad is still not working and the external volume buttons are not working so I ordered a new start/volume up and down board, hopefully I can get that sorted out.
So another one saved...shame that it only has a FHD display , I am really spoiled with the 4K display of the 910/930, if not I would sell these consumer laptops and use the 460 for work.
More to follow...

Last update...the 460 is fully up and running!
Replaced the power/volume board to get the external volume buttons to work.
The ribbon cable I bought did not work so I ended up buying a palmrest assy which still had the touchpad and ribbon cable installed.
I fitted that palmrest as the original one had some damage on one corner.

All is working fine now except for 1 USB port, the plastic guide in the port is broken - maybe I will replace that if I feel confident enough to solder on the mainboard.

As a last something I forgot to mention, the BIOS battery was dead giving me some beeps and prevented me to start the laptop. As at this early stage I did not if the mainboard would work so I took a new CR2016 button cell, recovered the cable connections from the original BOIS battery and taped the terminal on the + and - on the cell, protected it all and its working since. The prices for a new BOIS battery are nuts seen the cost of 1x CR2016 battery.

The final question...how much did I pay to get the yoga 460 working again?

Laptop 85€
480GB SSD 50€ (I could have done a lot cheaper and it did not had to be a 480GB drive but I can use this drive in another laptop)
Palmrest 30€
Wifi card 17€
HDD to mainboard cable 22€
Touchpad to mainboard cable 7€ (did not work)
Complete display assy 50€
Power/volume board 17€
RAM 8GB 41€

I paid all in all 310€, I do find these for around 300€ in good working order so its not been the deal of the century but it was a lot of fun!
