Macbook Serial Number

[anirudh]

Had my macbook logic board replaced. Now the serial number on the ABOUT THIS MAC window shows SystenSeUmb and theres no serial number. Is there anyway to enter the real serial number???

nope as its been deactivated because it had a serial number of someone else's Mac or its brand new from the factory with a different serial number that wouldnt match yours. you can find your serial number printed on your MacBook underneath the battery.

cant the apple store guys flash the real serial number on to the new logic board?

If the logicboard was replaced by Apple then they should have flashed the "old" serial number on to the new board. They probably forgot - if so, take it back in and they should do it while you wait.
