Lately my gf's moms house has been tearing up power supplies. They had
a laptop power source go bad, and then 2 more after that. Its weird
that all these could go bad at the same time. I also found out that
they have a guy doing some work around the house. I'm wondering if he
did something to mess up the wiring as most his other work was very
poorly done. The place is out of town so I don't have access at the
moment but wondering if you had any ideas on what could possibly be
going on?

thanks

Maybe a loose neutral (grounded conductor) between the meter and the
house? Or possibly the same thing between the power company's
transformer and meter? Either could cause the voltage to be unbalanced
enough cause problems.
You'd have maybe 150 volts on one line and 90 on the other instead
of 120 on each. It would probably be noticeable though on other things
as RBM said.
