MBP trackpad doesnt work after upgrading the ram.

Hi guys
I finally got my hand in the 4gb ram.
I followed Coltton guy to upgrade the ram.
The machine boot normally, I entered the password and I cant used the track pad.
I wonder what is wrong with it???
Can someone give me a solution???
Thanks.

 

Try swapping back the old RAM and see if the trackpad comes back?

Sounds like a driver got messed up during the shutdown/restart - I wouldn't think bad RAM could have that specific an effect.

 

I just tried it but doesnt work.

 

Try to do it again and now the keyboard is not working neither.

 

now try this:

Take out the new ram and replace the new ram again. Perhaps it's badly seated. If it doesn't work, your drivers are corrupted. Try reinstalling os x. everything will be fine. Btw, do you have bootcamp? Are these working under bootcamp?

 

if you want to figure out if its an OS driver problem or a hardware/plug issue... you can try turning it on and holding down Option for the boot menu and see if the kyyboard and mouse are working there.

do USB hooked up keyboards and mouseses work ok? the built in ones run off the USB bus too... if they do, you need to pop that thing open more, the whole bottom panel and see if somehow the pressure knocked a plug loose. You should be able to find most of the little tiny plugged in cables and make sure they are all in....

 

That was an hardware issues.
A technician helped me to look over it and said that I have to replace a Mobo .
Good thing that he replaced it for me right away.

 

You took it to the apple store and they replaced it for you right there? Thats some really good service, considering it technially went bad after you replaced it with a 3rd party ram.

 

Before that I put back the ram and did not say any word about replacing the ram last night
+1 to apple service
