I believe the serge damaged the port not the cable, which is why I am <br>
seeking software to test the integrity of internal things like the <br>
motherboard.<br>
My apartment is the upper basement of a house, where hydro is a part of my <br>
rent.<br>
However outlets on this floor seem to share circuits with other things both <br>
on this floor and likely in the rest of the house which may not be wired <br>
well. for example the fridge is on an outlet with other items, so, at <br>
least according to those who have already investigated a slight surge or <br>
feedback may be being sent.<br>
I suspect one of my older mac laptops has paid the price, my stereo which <br>
was just refurbished will stop, if something elsewhere int the house is <br>
turned on those kinds of things. Have to run extensions because the <br>
outlets are all under the radiators etc.<br>
The thing is though I cannot be sure just what is damaged, without a tool <br>
to test the internal items like the board itself. I only know the machine <br>
would not speak, even though sighted help at the time indicated the <br>
software was loading on the screen.<br>
