Hi, ive been lurking these forums for a while now and everyone always seems helpful so i thought id register and join in the fun myself! My first problem is that of a macbook... 2.1ghz, 1gbram, model no. a1181. Basically i bought 2 broken macbooks. the idea was to send them off and get them fixed, but the guy who usually sorts them out for me hasnt been in touch for a while, so i thought is try and save some money and bodge it myself. The macbook im fixing has a broken lcd and the panel around it is also cracked. The other mac display is intact so i figured i could just switch them over, not a problem. The only thing that concerns me is that once i go through the effort of switching them over that it still might not work. as it stands neither macbook has a HD or sled/caddy in it and im wondering if there is anyway of testing the other hardware inside without a HD? both macbooks switch on and the fan runs continuously (no sudden shut down after 5 seconds) however there is no chime and a blank black screen on both. the white power light stays on throughout. any help would be greatly appreciated!
