Laptop - Temperature problem - HP Pavilion dv6
HP Pavilion dv6
This HP Pavilion dv6 came to me last week. The problem was high temperature and make the computer restarting every two minutes.
Before describe the process step by step how to fix it, lets talk with simple words about temperature in a laptop. First of all you have to know that too much heat can kill your computer. In order to keep the temperature low, computers have a cooling system and temperature sensors. The sensors sent signal to the main unit when the temperature is dangerously high and give order to restart the computer immediately in order to prevent any damage.
How you recognise the problem
- Computer is generating a lot of heat
- Fan is start kicking on at shorter intervals
- If fan is making the usual noise and then one day it stops or the noise is getting louder, that is mean heating problem will be appear soon.
- Computer is starting up normally but after 1 to 4 minutes restart with no warning
What you need
- A clean table that you are going to work
- Set of screwdrivers
- One thermal paste (find one at http://www.ebay.co.uk/itm/New-UK-Arctic-MX-2-Thermal-Grease-Paste-Compound-For-PC-CPU-VGA-XBOX-360-PS3-UK-/280949908809?pt=UK_Computing_Thermal_Compounds_Supplies&hash=item4169eb6549#ht_1220wt_1186 )
- Two or three small plastic boxes for the screws ( I use small magnets to keep in order my screws).
- Pure alcohol ( http://www.ebay.co.uk/itm/IPA-Isopropyl-Alcohol-99-9-Pure-50ml-Dropper-Bottle-/140573765857?pt=UK_BOI_Medical_Lab_Equipment_Lab_Supplies_ET&hash=item20bad970e1#ht_2250wt_982)

OPEN THE LINKS UNDER THE PHOTOS TO WATCH THEM IN FULL SIZE
Remove the battery from the notebook. On the side photo a couple of screws are marked. Remove all of them also. Next the two plastic covers will be free to remove them.
Remove hard disk (very carefully). Using both hands try to open the two clips at the same time as shown in the picture to remove RAM card. Do the same thing for the second RAM card. Using a screwdriver remove the Bios Battery.
Using a screwdriver remove the two clips from WiFi card. Moreover, remove the screw and finally the WiFi card from motherboard.
Remove all the marked screws shown in the side photo. These screws must be kept together and note that are from the outside of the laptop. In addition to this, all screws have the same size except from the four small screws under the battery.
On this step pull out the cover shown in the first side photo. Moreover this plastic cover has a lot of clips which mean don't use any screwdriver because you are going to damage the plastics. On second photo check out the correct points to pull out the plastic cover.
Do the same thing to the other side, but be careful because the plastic has two wires underneath. YOU ARE NOT GOING TO REMOVE IT FROM THE LAPTOP YET!! JUST RELEASE THE CLIPS FROM IT !! See photo in step 6 to understand better.
Remove all screws shown in the side photo photo. Push in front the keyboard to see underneath and release the keyboard connector.
With your fingers take the blue plastic and pull out the two wires.Next step is to remove the plastic that has been prepared in step 5.
Remove all the wires from the motherboard as shown on the two photos
Time for the speakers to be removed.
Remove the four screws that keep the screen stable. Then remove the screen as shown in the side photos
Take out the plastic cover as shown in the side photo.
Take out the DVD-RW as shown in the photo. Moreover take out the Remote Control.
Remove the mouse pad as shown in the photos
Remove the cable of the sound card from the motherboard and also the screw that keeps the motherboard stable.
Remove the motherboard very carefully! Never put pressure on electronic components!
Turn the motherboard to the other side and remove the fan socket. After that remove the screws from number 1 to 6. The numbers can be found near the screws. Cooling system is free to be removed from the motherboard.
Remove the five small screws in order to free the fan and then clean the air vents.
Clean old thermal paste from the cooling system. In order to do that use the pure alcohol with kitchen paper. Pure alcohol is evaporated quickly and it is not going to harm electronic parts.
Clean the old thermal paste from CPU and Graphic Card with the same way.
Put back the fan to the cooling system and apply approximately 2mm of new thermal paste on the top of CPU and Graphic Card. With a toothpick the paste has to be spread uniformly. Carefully put back the cooling system to the motherboard.Then take the steps backward to put together all the part of your computer to the correct place.
