[QUOTE="MDJCM, post: 1535208, member: 117544"] Trying to work this one out. MBP ~2011 13", has had a spill on keyboard BUT, will boot perfectly from another Mac's firewire'd target mode hard drive. The only broken hardware appears to be a usb port and the trackpad. It otherwise functions fine. :Cool: If I try to boot it from its own drive or a Snow Leopard DVD, it gives the 3 beeps. So I've replaced the hard drive, and went to install from the DVD but still giving the 3 beeps. I mean, if it works fine over Target Mode, doesn't that prove that everything is fine except the HDD? :Confused::| (I am aware 3 beeps is a RAM issue, have tried every configuration of RAM/slot and the pattern is the same, no boot from own drive or DVD but ok boot over firewire) [/QUOTE]
