I updated my Manjaro installation yesterday after about a month or two of non use. After updating I closed the lid for about half an hour. After resuming from sleep the touchpad has been completely unresponsive and somehow it has persisted into my windows 10 installation. Does anybody know how to troubleshoot this? I’m borderline Linux illiterate.
Thanks in advance.
Welcome to the forum! 
That is not how you’re supposed to run Manjaro. Manjaro is a curated rolling-release distribution and is meant to be kept up-to-date. Updates are always announced on dedicated threads under the Announcements category, along with the caveats that come with the update, if any. As a rolling-release distribution on the cutting edge, there regularly are some major changes to the underlying system, often requiring manual intervention ─ the procedures are then explained on the aforementioned announcement thread.
If your usage includes months of non-use, then you are always going to be running into difficulties when upgrading your system, and then you will probably be better off using a fixed-point-release distribution.

Unfortunately I haven’t seen anything related to my problem in the announcements or known issues thread. I’ve already applied the cups manual intervention. Currently browsing for touchpad related issues. Is there anything else you can recommend?
Didi you reboot after the update or just closed the lid?
I think I did. I typically reboot immediately after an update to prevent issues like this from happening.

I’ve seen this several times in journal since the update. Not sure if that helps.
