I'd like to ask again about grammatical question,please advise!?

I ume I can't get an answer I can understand, so I would ask again expecting a clear explanation. A solution says "Being informed, the computer repair technician will restore lost data till the next morning." should be changed to "Informed, the computer..." Could you advise me why the 'Being' should be deleted in the first sentence if the solution points out correctly. Thanks in advance for your help.
