hp pavilion 11 ethernet port fried.. solution..?

[koen1]

Hello all,

new to the forums here, and decided to join because I have a bit of a problem with my laptop..

I did something pretty stupid today. I was trying to program a hitachi PLC with my laptop, and accidently hooked the ethernet cable up to the wrong port on the PLC (the port that would normally connect to a touchscreen / HMI) with the result that my ethernet port on my laptop got fried. After a few seconds smoke started coming out of my laptop from underneath the keyboard so I quickly janked the ethernet cable out. It was only in there for a few seconds but the damage was already done.

On the bright side: everything seems to be working OK still. Wifi is also still working. Only problem is that this laptop has only one ethernet port and I really need that port.

I took the cover of but nothing obvious pops out. I know it's kind of a vague question to ask; but would anyone have any ideas on what might've broken and how to check what might be broken and what not?

I'm not verry familiar with computers by the way, so excuse my lack of knowledge.

Many thanks in advance

What is the complete product name or product number of your notebook?

If your notebook has usb ports available then the solution would be to purchase a usb to ethernet adapter.

They do work quite well. 

Otherwise you will need to have the systemboard in the notebook replaced. 

You can even purchase one at Walmart if you happen to live near one.

The full name is 11-n001ed

I already considered the usb - ethernet option, and will probably use that for the time being, but would still like to get my ethernet port working again

I've read That this laptop has a network card / wifi card in it. Would you think this might be broken and would replacing it fix my ethernet port? Any way of testing this? I have a multimeter if theres anything i can measure to check the condition

this is the card I was talking about. Could this be the cause?

A network card is not present, there is a wireless adapter.  

Ultrabooks like  yours that have RJ-45 ports do not have seperate wired adapters that can be replaced.

The NIC is part of the systemboard and is not individually replaceable.  

Since yours was smoke checked there is liable to be some trace damage on the systemboard.

Using a mulitimeter is not going to help in any way. Even back in the old days of fat notebooks the NIC was part of the systemboard. An ultrabook is not a desktop. Even desktop motherboards have the NICs integrated into the chipset.

A systemboard replacement is how your fried network port will have to be resolved. Otherwise, to avoid the expense of systemboard replacement, use the USB to NIC adapter cable.

Under the warranty, owner induced damage of the RJ-45 port will not be covered. It is an excluded type of damage.
