Check All Power Cord Connections
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)
Charging Light is Flashing but Computer Won't Turn On
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.

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.

Mouse is Skipping Around Your Screen
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...
Sound Not Playing
The speakers aren't playing any sound.
Turn Off Mute Button and Raise Volume
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.
Check Sound Settings
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.

Drive is broken and needs replacement

The computer gets very hot or sometimes shuts down after becoming hot. These are the possible causes and solutions
Fan is Blocked
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.
Fan is Not Getting Power
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.
Thermal Paste Needs to be 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.
