Hi @kylew87212
Check if there's a part number on the touchpad and search online for the number to find suppliers.
Here's the [https://download.lenovo.com/consumer/mobiles_pub/ideapad_slim_5_5i_14_16_hmm.pdf|hardware maintenance manual] for the laptop that may help.
Go to p.59-p.60 to view the procedure to remove the upper case with keyboard assembly, so that you can see if there is a part number on the touchpad.
The [https://pcsupport.lenovo.com/us/en/products/laptops-and-netbooks/ideapad-s-series-netbooks/slim-5-16irl8/82xf/parts/display/compatible|parts list] for the model, doesn't show the touchpad as a separate item as it is most probably included as part of the C-cover with keyboard assembly. Click on ''Machine Type > Select Commodity'' to see all the available parts and their part numbers.
