Power adapter and Laptop

[Thete]

Laptop is about a year and eight months old. Plugged in daily as it's a gaming beast, MSI GT70. Was happily playing WoW in a different room than usual, and suddenly, the adapter makes a strange noise. Next thing I notice is it isn't charging anymore. Try a few different plugs, adapter is dead.

What I want to know is how likely whatever caused the noise (be it a fuse or something) also fried the laptop?

Any help at all?

Can you run it off the battery without the charger plugged in? Or off the adapter with the batteries taken out? Or is it just not working either way? Was it flat when this happened?

The adapter making a noise could be the fuse in the plug (that's if plugs have fuses where you are), but it could be the adapter itself. It's hard to know about the laptop, but you should be able to get it to switch on, even a little bit, off the battery with the charger not plugged in if it's the charger/adapter that's gone.

It ran fine on battery, I didn't initially realise the noise had been the pack until I looked down at the battery indicator and realised it wasn't charging. I'm infinitely glad there was no smoke or strange smell, too.

I did think fuse,  it's beyond me actually knowing if it is that or how to fix it.

If you have a computer store locally, you could maybe take it there an see if it charges if you plug it into another laptop charger with the same current or whatever. Optionally, maybe a friend has one you could try it with.

In truth if you heard the noise from your power supply and it died it sounds like their might have been a power spike.  That noise would actually be the adapter doing it's second job of protecting your laptop from the surge.  If the adapter can't handle the power being sent into it it's supposed to blow a fuse and stop working before damaging the computer.  Adapters are cheaper then laptops and no one is going to buy another laptop from a company that just lets your equipment fry.
