Thread: Macbook pro trackpad doesn't work after upgrading

Hi guys

Finally got my hand on the 4 GB ram. I have continued to improve Colton type ram. The machine will boot normally, I entered the password and I can not use the track pad. I wonder what is wrong with her. Can someone give me a solution?

Try exchanging the old RAM back and see if the trackpad?

Sounds like a driver in a bad state during the shutdown / reboot - I will not think badly of RAM you can have a specific effect.

I want to tell you that I have tried it earlier but it does not work.

Remove the new ram and replace the new ram again. Maybe sitting is bad. If it does not work, the drivers are corrupted. Try to reinstall OS X. everything will be fine. BTW, do you have bootcamp? Are these working under bootcamp?

If you want to find out if your operating system a driver problem or a hardware / plug question ... you can try turning it on and hold down the option to boot menu and see if the mouse keyboard and are working there.

This is a hardware problem. A technician helped me to look over and he says I have to replace a Mobo. Well I will replace it immediately.

You understand the Apple Store and are replaced there by yourself? That is a really good service, given that he was bad technically after you replaced it with a 3rd party ram.

Before I return the ram and not say a word about the replacement of the ram last night
+1 to apple service.
