Hi everybody!
Yesterday night I wanted to change the fan and the heatsink of my Lenovo X60T tablet (which I am using to study) because the fan was not far from being completely wrecked and made noises so that you could not work any longer without getting insane. So I ordered a new one.

Then I surfed the net and didnt find any tutorial from the beginning to the end so it took a little longer to exchange the fans because I decided put a tutorial into the net by my own. And here it is :).

You can torn it down into the following steps:

1) remove the battery
2) remove the keyboard
3) remove the HDD
4) remove the keyboard cover
5) prepare the motherboard for being clipped out
6) clip out the motherboard
7) replace the fan and heatsink
8) reassemble everyhing

What you need:

1) patience
2) caution
3) you should be grounded, electrically uncharged
4) very small screwdrivers
5) small nippers
6) some mechanical and electrical skills
7) time, dont do the replacement when you are in a hurry. It took me (with taking the photos) almost 3 hours
8) and finally…patience :)

So lets start:

1) remove the battery
Now thats an easy one. On the bottom side of the laptop where the VGA output is there is a small switch that you need to unlock. Then press the unlock switch on the bottom center of the laptop and remove the battery.

2) remove the keyboard
To remove the keyboard you need to remove the screws on the bottom side of the laptop where you can see the keyboard-symbol. Should be 4 screws.

NOTE: The screws have letters A,B and C written on the holes. Keep each screw-group together as they have different length. That will help you when you reassemble the laptop!

Then on the top side just push the mouse buttons a little into the direction of the display. Then the keyboard should turn loose and you can lift it up.

NOTE: Dont lift the keyboard and throw it away because its connected to the motherboard.

Pull the small circuit-board directly upwards (towards the sky ;) ). It doesnt look like one but it is a connector!

3) Remove the HDD
On the bottom right side (where the power connector is) there is a screw with a HDD symbol. Open the screw, remove the cover and pull out the HDD.

4) remove the keyboard cover
So its time to get rid of more plastic. On the bottom of the laptop, remove ALL screws. All screws should have a “chip”-logo on the side. Get rid of them. Turn around the laptop and carefully remove the top cover.

5) prepare the motherboard from being clipped out
Now we prepare the motherboard. There are some connectors on the motherboard that would get damaged if you just pull the board out. Those are:

a) WIFI Antenna
b) display connector
c) pcmcia slot
d) power plugs on the board

But first of all remove ALL metal (silver looking screws) you can see. Should be 2. Here is a picture where I marked the parts a, b, c and d and the screws (screws are marked without letters). You can click on the picture, it is made with full resolution.

The display connector b is a little difficult. You have to remove 4 screws first and then clip it out (under the circuit board there is also a connector) directly upwards. Difficulty comes when you want to remove the motherboard because you got to bend the display connector towards the display. Just pay attention you dont break anything. It definitely fits!!! I tested it!!

6) remove the motherboard
Now comes a tricky part where you need patience. Clip the motherboard CAREFULLY out. I began to bend the plastic case of the laptop a little where the audio ports are and lifted it there. Then I raised the board a little where the PCMCIA adapter is located and then where the VGA port is. You can lift it.

You dont need to remove any futher plugs etc. Just lay the board backwards onto the display. To prevent scratches you can put a little paper onto the display first.

7) replace the fan unit
Finally we can replace the fan and the heatsink :). We need to remove 4 screws here.

Then partly remove (not completely) the black plastic tape and the power plug.

NOTE: The power plug from Lenovo sometimes differs. My laptop had a 4-pin connector but with only 3 cables attached and the exchange part had a 3-pin connector. The 3-pin connecter fits perfect into the left three pins of the 4-pin connector on the board.

Then build in the new fan and pay attention if both heat plates are covered with heat-conductor.

Finally you just need to revert those steps back until the laptop is reassembled again.
If you have done everything right then it should look like this:

I hope you enjoyed it! Like always feel free to comment!
