Laptop touchpad is jumpy
July 29, 2013 3:43 PM Subscribe
I have a new laptop (Acer with Windows 8) and the touchpad will intermittently go all goofy. It'll make the cursor jump around the screen randomly and open windows as if I'm clicking, even if I hold my finger perfectly still on the pad. My question: Is there any chance that a third-party power cord is causing this?

I have a second power cord for work that I bought through Amazon, which specified that it was compatible with my laptop model. It's the same polarity, same output, and the plugs look identical. But I can only get the touchpad to act weird if I'm using the third-party cord.
This is not a "tap-to-click" issue -- the cursor will leap all over the screen, change the size of text or icons as if I'm holding down the ctrl key, and stuff like that -- again, while I'm holding my finger still.
I brought both cords to work today and have been switching them back and forth. Since the problem is intermittent, I can't guarantee that this only happens with the third-party cord -- but so far that's the case. It will sometimes act up with the third-party cord plugged in; it has yet to act up with the Acer cord plugged in.
I've been through customer service and gone through all their recommended steps, from changing the touchpad options up to and including resetting the laptop back to factory default. The next step is to mail the laptop back to them -- it's still under warranty -- but I'd rather not if the cord is somehow the culprit. Plus, if it is the cord's fault, the techs won't be able to find anything wrong.
So: Is there any chance that a third-party cord, which seems totally compatible in every other way, is causing the touchpad to act weird?
