Ethernet LEDs always on

[Atcold]

I have a HP Pavilion dv7 2215el.

Recently (a couple of month ago) I noticed I could not anymore connect to the wired connection.

I can "see" the hardware (so, drivers are fine) and its MAC address looks fine.

What I've noticed is that both LEDs, the green and the orange one, are always ON, no matter if the laptop is connected to the router or not.

The dv7 model I have is prone to static electricity problems which are fixable by removing the battery and keep pressing the power on button for several seconds. But this didn't help this time.

I've read elsewhere that I need to reset the CMOS by moving some jumpers after removing the battery, but I wanted to ask here first what I should better do.

Thank you very much for your help.

For the moment I will keep using the WiFi.

Hi @Atcold , 

Thank you for visiting the HP Support Forums and Welcome. I have looked into your issue with your HP Pavilion dv7-2215el Entertainment Notebook and connecting with Ethernet Cable. Here is a document on how to connect with the Wired Ethernet connection using the Connection manager from HP. The led light will always blink. It is suppose to do that.

Hope this helps.

Thanks.

Hi @Mrstenter,

The LEDs are weakly ON all the time. With and without cable connected and they are not blinking. Just steadily weakly ON.

This is my current configuration. I hope it is going to help you understand better my situation.

 Tomorrow I will try to connect to my office's wired connection and with a 3rd cable, just to be sure the problem is not at home... P.S. Your editor is turning MAC addresses, in a code wrapper, which contain ':' and 'D' into smiles...

Update

I've brought the laptop to work. Nothing worked even there.

I've reset the CMOS by removing the coin shaped battery for 5 minutes and puting it back. Upon the start up the machine prompted me that the CMOS checksum was gone bad and that a reset would have been performed. After all of this, the Ethernet periferal is still down.

I believe it is a hardware failure. Is there any way I can replace the HW or what would you suggest to replace its functionality? An external USB2 to Ethernet converter? Something else?

Thank you for your help,

kind regards.

Hi @Atcold  ,

You will need to have this Notebook tested at a repair facility. The can test each part to see what would be causing the issue. You can do a system restore. System restore will help if something automatically updated and did not go well on the Notebook. I do not feel with the message you posted of the display settings that it is a hardware issue.

Hope this is helpful.

Thanks.
