When the lights flicker, your computer feels it too.
Storm season is here, and down here in Cornwall that usually means the odd power cut. A laptop just carries on running on its battery. A desktop computer switches straight off, and you lose whatever you were in the middle of. Either way, the surge when the power returns, or lightning nearby, can damage a computer or router.
A few habits help. Save your work often. When a storm is right overhead, switch off and unplug at the wall, router included. After a cut, wait a few minutes before turning things back on, because the power often flickers on and off before it settles. A surge-protected extension lead is worth having too.
If you use a desktop for work, or run bookings for a holiday let from one, it's worth thinking about a UPS. That's a battery box that sits between the wall socket and your computer. When the power goes, it keeps things running long enough for you to save your work and shut down properly. A laptop doesn't need one, as its own battery already does that job.
Not sure whether your setup needs one? Drop me a line and I'll point you in the right direction.
