Hello,
Do you know the purpose of the component that is not welded in the lower right corner of the red square on the picture of step 12: http://d3nevzfk7ii3be.cloudfront.net/igi...
Someone tells me I can not have my backlight re-working without this component, but I think it simply does not work because of a liquid.
Any ideas ?
Thanks in advance
I just replaced the logic board, and all went fine, as far as I can tell. However, my new battery is still in transit, i.e: I do not have it at hand. My question is, how critical is it to have a battery in this model....given all the "do not remove battery or else" warnings. Is it OK to try to boot it just with the regular power supply? I do not want to fry my new logic board, so I need some informed opinion on this...
