After installing more RAM, my MacBook Pro 15' will not power up?
I am currently using the 10.5.8 OS and want to upgrade to the 10.6 S L. Because 512 was not enough memory, I ordered 4Gb(2X2). After installation, the machine will not power up.I tried several senarios with the modules and slots, but nothing works except to replace the old module. Got any ideas ???
Esta é uma boa pergunta?
