Data AWK or SED to add string at specific position

Greetings.
I don't have experience programing scripts. I need to insert a string in a specific position of another string on another file (last.cfg), for example:

File last.cfg before using script:
login_interval=1800
lcs.machinename=client04

File last.cfg after using script:
login_interval=1800
lcs.machinename=newclient04

I read about awk and sed comands, by I'm not sure what use and how. Smilie
Please, I'll thank so much if someone may help me or tell me if this problem has been solve on another post.
