Message 2 of 2. Hi zdravko , Welcome to the HP Forums! I need the exact model number and product number of you PC. Did you make any hardware or software changes on the PC? You can also follow the below steps: Use HP Support Assistant Network Diagnostics: If your computer has a wireless key or button on or near the keyboard and the wireless activity light is off or amber in color, then press the key or button to enable your wireless adapter.
If problems persist, continue using these steps If your computer does not have a wireless key or the wireless activity lights remain off or orange then continue using these steps. From the Windows desktop, click the HP Support Assistant icon in the notification area at the bottom right corner of the screen. If a welcome screen opens, select the options you want, and then click Next.
In the My devices screen, select your device from the options listed. The My Devices menu screen is displayed. On the My devices menu screen, click Internet and Security. Click HP Network Check. If a User Account Control message opens, click Yes to allow the computer to make changes. If the diagnostic test finds no issues, close the windows and continue to the next section. If the diagnostic test finds one or more issues, continue following the steps in this section.
Click Possible Root Causes. Click one of the tool icons for steps to resolve the issue, then follow the on-screen instructions. After completing the instructions, click Re-check. HP Support Assistant checks the network connectivity. Use Windows 7 Network and Internet Troubleshooter. Click Troubleshooting, then click Network and Internet. Although it may sound obvious, the adapter can become loose without even knowing. If it's plugged in partially, it can make it seem like the adapter is not working, but it may not be getting power from the wall outlet.
When in doubt, a good way to make sure it is plugged in properly is to disconnect and reconnect the plug. Many laptop AC adapters have a power indicator light on the adapter brick.
Check for this indicator light and if there is one, make sure it is light up with a green light. A power indicator indicates that the adapter is receiving power. Some wall outlets require a light switch to be in the on position for the outlet to be active. Many newer houses, apartments, and condos feature this type of wall outlet. If the light switch is on, verify the wall outlet is working in general. Use a voltmeter to measure the power output and verify the outlet is functioning properly.
Alternatively, you can also try another wall outlet. Also, double check the circuit breaker and make sure nothing is tripped or turned off. Most laptop AC adapters come in two pieces.
Make sure both of those pieces are connected firmly and securely. The two pieces connect at the rectangular box piece, often called the brick. You can verify the connections by disconnecting and reconnecting all cables. Although it may seem obvious, the adapter can become disconnected from a laptop pretty easily. The metal tip on the adapter cord needs to be firmly attached to the laptop for the laptop to receive power from the adapter.
Also, in the tip on the adapter or the connection on the laptop, there is often a small metal pin. Make sure this pin is not bent or broken as it can cause a problem with the laptop receiving power from the adapter.
