HP Pavilion dv6-2158nr Troubleshooting

The computer will not charge while plugged into the a power outlet.

Check the power adapter connections and where it plugs into the laptop.

If the adapter is plugged into a power outlet and no light is flashing on the adapter, then there is either a problem with the adapter or the wall power outlet. Check to make sure your electricity hasn't been shut off.

Note: (If power is going to the laptop through the adapter, there will be a light on the front of the PC and one on the adapter that will be flashing slowly)

Detach the battery from the laptop and use laptop with only power adapter supplying power.

If the computer functions only while plugged in and dies immediately or a short period after, then your battery may be old and needs to be replaced.

The built-in laptop or a external USB mouse will not move cursor.

Make sure the button above the mouse pad is not red because it disables the mouse.

If that does not work, then it may be disabled by Windows. Click on "Start" and search for "Device Manager". Expand "Mice and other pointing devices", right click on each device, and make sure they are not disabled.

Follow the link to HP's device driver page and download the driver to use built in mousepad: http://h10025.www1.hp.com/ewfrf/wc/softw...

If you're using another mouse, make sure is attached securely and getting power.

If you are using an external mouse, make sure it is connected securely. If the mouse is wireless, the batteries may need to be replaced.

If you are using the trackpad, wipe it off with a dry cloth. If that doesn't help then reinstall the driver by selecting Driver-keyboard, Mouse and Input Devices and downloading the touchpad driver here: http://h10025.www1.hp.com/ewfrf/wc/softw...

The speakers aren't playing any sound.

Check that the mute button is off and increase the volume. Play something that has sound on the laptop and listen carefully for noise

Check the audio jacks if you are using external speakers or headphones and make sure you have plugged them in correctly to the audio out jack, which is positioned on the far right of the laptop. Also check if external speakers are plugged into power.

Right click the sound icon on your start bar and click playback devices. Make sure the speaker arrangement you are trying to play on is enabled in this menu.

Test the playback by right clicking on your speaker icon on your start bar>playback devices>right click on speakers>test. Check if you can hear any noise coming from either of the speakers (Note: There will be a loud "bing" noise if it is correctly enabled).

Check to see if your playback device is not disabled by following the previous route and checking that the disable button is not checked.

Search for audio playback on your start bar and select "Find and fix audio playback problems" and follow the instructions that follow.

If you have more than one playback device, such as a pair of external speakers, follow the previous route once again to make sure that they are enabled.

If all of the above do not work, it may be an issue with your speakers and you'll need to replace the built-in speakers. You can do so by following the repair guide on this device's main page.

The screen remains black when you press the power button.

Try a hard reset by holding down the power button for 30 seconds until the computer shuts do

If none of the above work, your brightness may be turned down. Turn up your brightness and contrast of your monitor by using the keyboard shortcuts located on your laptop.

Before breaking open your device, and if possible, plug in another monitor into the VGA port on the side of the computer.

If the screen is on and displays properly but your device's LCD monitor will display anything, try the next step.

If using an external monitor, you may have to change your display settings by searching for "Adjust screen resolution" from your start bar and adjust accordingly to the dimensions of your monitor.

The problem is with either the device's LCD monitor plug-in and needs to be reconnected by using the repair guide.

If your monitor screen cannot turn on and you have tried all previous steps, your LCD monitor may be broken and you will have to replace it using the repair guide.

The CD won't play or be read in disk drive.

Your computer may not know to what to do when a disk is inserted. Check to make sure the computer is actually seeing the disk by holding “start” and pressing “r”. This will bring up the Run window and you can type “d:” to read the disk if can be read.

The disk drive may have come loose from the main board. Push the disk drive into the computer to reattach it.

Insert the disk you are trying to read into another computer. If that computer cannot read it, the disk must be replaced.

If the drive is properly connected and it still won’t read any disk, the drive must be replaced.

The computer gets very hot or sometimes shuts down after becoming hot. These are the possible causes and solutions

Excess dust can clog the computer’s fan and it cannot dispense heat as well. Aim a can of compressed air and the vent on the back of the computer and blow into the vent. A bunch of dust should be dispersed out.

When the computer is powered, the fan should be ejecting heat from the vent on the back of the computer. If no heat is coming out or you do not hear the fan spinning, it may be broken. The computer will need to be disassembled and the fan and heat sink assembly replaced.

The thermal paste that redirects heat from the processor to the heat sink needs to be replaced. This means most of the computer will need to be disassembled and the fan and heat sink assembly will need to be removed from the motherboard. Under the fan and heat sink there are three computer chips. Each of them will have some gray residue on them. Wipe the residue off using a paper towel, being careful not to touch any other components. Then squirt a dime-sized amount of thermal paste onto each of the computer chips and attach the fan and heat sink assembly back.
