My macbook pro's trackpad is not working.

Question

I have had my macbook for 2 years. I have had no problems and no complaints till this point. However, my trackpad stopped working, now I can't do anything without a mouse. When just using a trackpad it moves without me touching it and opens random apps. I really would like to know how to fix it, or how much it will cost to fix it. (no my warrenties are gone.)

Answer 1

Hi again,
Here are some additional recommendations from an earlier post by Linc Davis:
1. Follow the instructions in this support article.
2. Reset the System Management Controller.
3. If you're using a Bluetooth trackpad, investigate potential sources of interference, including USB 3 devices.
4. A swollen battery in a MacBook Pro or Air can impinge on the trackpad from below and cause erratic behavior. If you have trouble clicking the trackpad, this is likely the reason. The battery must be replaced.
5. There's a report that a (possibly defective) Thunderbolt Ethernet adapter can cause the built in trackpad of a MacBook to  behave erratically. If you're using such an adapter, disconnect it and test.
6. There's also a report of erratic cursor movements caused by an external display that was connected but not turned on.
7. If none of the above applies, or if you have another reason to think your computer is being remotely controlled, remove it from the network by turning off Wi-Fi (or your Wi-Fi access point), disconnecting from a Bluetooth network link, and unplugging the Ethernet cable or USB modem, whichever is applicable. If the cursor movements stop at once, you should suspect an intrusion.
Cheers,
