I have an HP Pavilion laptop, and a few days ago it's battery was low so I plugged in the power adapter cord to charge it. As soon as I connected the cord the laptop died.

I have a power surge protector to protect it from any voltage fluctuation, so it can't be that.

I showed it to a service centre and they told me that the laptop's motherboard was damaged. They didn't tell me why the motherboard got damaged, but I would like to know.

I would like to know why my laptop's motherboard got damaged and how to protect a laptop from this type of accident in the future.

  • Was there anything possibly wrong with the power cord or laptop? like things hanging out/cracked/broken? Had you dropped it recently, or spilled anything? Is this an HP-brand power cord, or a third-party one? Also, are you sure you're plugging it into a wall outlet with the correct frequency (I think the US usually uses 60Hz, while the rest of the world uses 120Hz?)

  • Was the laptop on when you plugged it in?

  • Everyone uses 50-60 hz. Its the voltage that's different. SMPS generally work with different voltages with no issue tho.

If the "service center" said "Its mother board damage"

Its probably defective, and dont want you to ask them to replace it...

Go ahead and ask them to replace it.
