When I get a call from a customer saying their computer no longer switches on,
And having suggested the obvious – like replacing the fuse, trying a different power supply cable and the even more obvious…
I ask if they’ve had a power cut.
Got to ask because you never know!
If none of the above has done the trick, it tends to be one of the following…
A faulty Power Supply Unit (PSU),
A dead motherboard,
Or if it’s a laptop, a faulty battery as this can sometimes prevent the computer from starting up.
In my experience though, in around 95% of cases the PSU tends to be the culprit.
But a blown Power Supply Unit is something that can easily be prevented…
And for as little as £15.
What you need is a surge protection cable.
This will stop any power surges from a badly wired or faulty electric circuit or even a thunderstorm lighting strike ever reaching a gadget or device that’s plugged in to the surge protector.
So rather than spend £60 – £70 on a replacement PSU,
Around £250 on a replacement motherboard,
Or £600 on a new machine, this is a no brainer.
