Upgraded to 2Gb ram and keyboard/trackpad stoped working

Hi,

I'm trying to upgrade my PB to 2Gb from Kingston (KTA-PB533/1G, not value line) but, even the ram being recognized and "OK", a few minutes later of installing it, the keyboard and trackpad stop working...and the only way to get it working again is switching to my original 512 slot. Even repeating the process, i can't resolve the problem... I believe it's something with the bluetooth..when it happens, with the 2Gb ram, i don't now why, but the bluetooth turns on too and after this, every time i reboot, the bluetooth startsup! Only switching to original ram solved the problem until now ( I hope)...

It was told me by the seller that this is the compatible slots to my PB by Kingstone and it was confirmed by apple support when he send my serial number to confirm.

Can you help me on this?

Many thanks in advance and sorry my english.

what OS are you running

Its odd that Ram that is recorgnised by the system is interfering, is it somehow hitting the keyboards ribbon cable

Hi louishen, thanks for your help.

In fact, after read your answer, i had a look to that ribbon cable and, although beeing plugged, the plastic part that locks the cable was oppened. I'm gona try now get the ram to work propelly.

But, if that's the problem, why the bluetooth interference? I,ve no doubt about the bluetooth involvement in this problem.

I'll let you know tomorow about the result.

Many thanks again.
