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

Have they seen lights get brighter or flicker, then call the power co.
if it affects supplies everything else could be suffering from stress.
Have there been storms or power interuptions. Good quality surge
suppressors should be used on everything they care about. Its probably
not a worker but should be looked into, the power co is free, they
know what to look for and usualy come out quickly. Once I had my
incomming lines loose and it was cutting out power, wires on the main
panel could be loose, a bad pole transformer are things the power co
will check for free.

Assuming this in North America somewhere?
Look for broken/bad neutrals and or if the amateur doesn't know what
he is doing he may have mixed up and/or connected ground and neutrals
together thinking (incorrectly) they are the same. Or sloppy/poor
connections when something wasl altered repaired or extended.
Because if a neutral is open one can with North American 120 - 0 - 120
standard wiring get 240 volts across something designed for 120 etc.
