Thanks for the info. So basically you can (Should) only work on Apple Machines (And Others) that are out of warranty. No prob.
Yeap...that makes common sense,if you still have a warranty or applecare,go to tha applestore or gravis etc. But if its an older machine or the garantie has run out then don't hesitate to contact me for help!
Don't forget,some of the latest problems like battery charge or trackpad discoloration(macbook topcase) problems can still be covered by apple and are free of charge depending on your serial number.
