Laptop Maintenance/Overheating Prevention: Ensuring stability and performance of your laptop requires proper care and periodic maintenance.

In order to combat overheating, most laptops have a heatsink and a fan attached to the CPU and other vital microchips.

The heat sink absorbs the heat generated from the microchips.

And the fan helps transfer that heat into the outside air by blowing it.

The special paste between the heatsink and the CPU is called thermal grease.

It can withstand very high temperatures.

And ensures proper heat transfer between the microprocessor and the heatsink.

Over time the thermal grease dries up.

And the fan sucks in debris from the outside that coat the internal components.

Both of these outcomes decrease the efficiency of heat transfer and reduce the cooling of the system.

As part of your laptop maintenance.

You can reapply the thermal grease and clean all dust and debris from the inside of the laptop.

Laptop Maintenance/Overheating Prevention

1. Things You’ll Need

Laptop computer

Grounding strap (optional)
Precision screwdriver set.
4-8 small containers to collect screws (recommended)
Can of air
Thermal grease
Plastic prying tool

2. Place the plastic screw collection containers in a straight line.

You will fill them in one by one in one direction.

  • Make sure to place the screws from separate areas into separate containers.
  • For example Screws under the keyboard go inside one container and screws holding the motherboard goes in another.

3. Prepare a clean workspace.

4. Inspect if the laptop has multiple covers or one solid cover.

5. If it has one solid cover, skip to the next part of the article.

6. Using Philips ph00 screwdriver unscrew any screws that are on plastic covers first.

7. Take out every screw on the back case.

8. If the laptop has a CD drive, slide it out by just pulling it out perpendicular to the laptop

9. If there was a rectangular chip (RAM) under of the covers you may pull it out by lifting it up and sliding it out at a 45 degree angle.

10. Remove any screws that were under the plastic covers and the RAM chips.

11.Locate and remove the hard drive.

It should be a rectangular shaped box that was under one of the covers.

  • In order to remove the hard drive, slide it out or if it just pulls out, disconnecting the SATA cable attached.
  • If there is a silicone sleeve pinch it and wiggle it out of its enclosure.

12. Flip over your laptop and open the lid.

13. Inspect the keyboard to see if it has seams or if it is uni body with the hand rest.

If you can’t tell then assume it is uni body.

  • If there is a plastic cover, pry it off with your prying tool by going around the edges. Take off the cover and remove the screws underneath.
  • If the keyboard does not have a cover, then there should be four to five small push tabs above the function keys. Use a flat head screw driver to push these in.

14. Lift off the keyboard.

There will be a a large ribbon underneath.

15.Identify if the ribbon connector has two tabs on on the sides or one tab in the middle.

If there is one tab pull it perpendicular to the mother board. if there are two tabs push the m parallel to the mother board and away from the connector.

16. Remove any screws that were under the keyboard.

17. Put on the grounding strap or touch a large metal object in order to discharge the static electricity in the body.

18. Review what you see inside.

There will be many different cables and ribbons connected to the motherboard.

Unplug the cables by pulling on the plastic connectors. Release all the ribbons by unlocking the small plastic latches on the motherboard.

19. Using the prying tool go around the seam in-between the case and the hand rest in order to unlock all the clips holding them together.

20. Remove the hand rest revealing the motherboard. (Largest board inside the case)

21. Disconnect the display cable.

It is a large black bale wrapped in cloth. pull on it by pinching the loose cloth or plastic in perpendicular to the motherboard

22. Remove any remaining screws on the motherboard.

23. Look for a small green board with two or three skinny antenna cables plugged in.

The board is called a network card.

24. Pluck out the antenna cables by pinching them and pulling them out perpendicular to the board.

25. Pull out the small network card by sliding it at a 45-degree angle.

26. Slowly wiggle the motherboard out of the case by lifting up the side that’s closer to the center.

When one side of the card is out of the case slowly slide out the motherboard in the direction away from the edge of the shell.

27. Blow off all dust and debris inside the case and on the surface of the motherboard using the air duster.

28. Place the motherboard on a clean surface.

Flip it to the side with the heat sink and the fan are located.

29. In order to take out the fan, unplug the wire coming out of the fan and into the motherboard.

Remove the screws around the fan.

30. Clean any lint collected between the heat sink and the fan with the air duster.

31. Using the air duster blow out the dust deposited in inside the fan.

32. Remove all the screws going through the heat sink and detach them from the motherboard.

33. Using your prying tool scrape off any dry thermal grease paste off the heat sink.

Using a microfiber cloth, carefully wipe any grease still on the CPU. Be very delicate wiping the CPU.

34. Using the thermal grease syringe, squeeze out a little drop on the CPU.

Spread it around the edges using the tip.

35. Re-seat the heat sink on the motherboard and replace the screws.

Do not overtighten them.

36. Reposition the fan back on the motherboard.

Reattach the unplugged cable and replace the screws.

37. Reassembling

Place the motherboard back into the case.
Replace only the screws taken out during the motherboard removal.
Plug the cables back into their respective plugs.

38. Insert the ribbons into their respective slots.

Push the two tabs on the sides perpendicular to the board or if it only had one tab push it down perpendicular to the board.

39. Reposition the hand rest and reattach all the wires and the ribbon cables for it.

Apply the method from the previous step to the cables and ribbons on the hand rest.
Close the laptop lid, flip the laptop upside down, and re-seat the hard drive.
If you took out the optical drive, slide it back in now.

Replace the screws from the back cover and insert the battery.

40. Get the tips

Note if there were any larger screws and which holes they went in.

Look over every hole one more time and make sure you did not leave any screws behind.

Take a picture of the motherboard before you started removing the cable ribbons so you will know to put it back later.

You may also use a sheet of paper to trace an outline of the holes from where you removed the screws and place the screws on the sheet of paper in their respective positions.


  • Be very careful not to over-tighten the heat sink and the motherboard screws.
  • Do not grab the motherboard by the electrical components.
