I finally convinced my friend to ditch her Dell and get a brand new MacBook Pro. I had them install a second 1GB of RAM in at the store, which took a long time because they said the first RAM chip they put in was bad. Well, we got the machine home, plugged it in and nothing. The light on the front by the latch turned on, and I could hear a faint clicking sound coming from the computer. But no Apple chime and nothing on the screen. Did they screw up the RAM at the Apple store, or is there a bigger problem that they didn't discover and assumed it was the first RAM chip they put in. Any insight would be great. Thanks.
