I'm a slider by nature member of Facebook group of people who affect electronics on the internet and throughout time it talks of us cell phones key cards lights if upset tired excited car alarms door alarms computers machines go haywire and hey forget even trying to wear a watch. So hey the next time the lights go out check your date... It may just be one of us...

Some people have that happen to them. A friend of mine did too and it cost her a lot of money buying new equipment.
But she's learnt a way to deal with it and it doesn't happen anymore. It is basically accepting the frequency of electricity and allowing it so you don't clash with it any longer.
