Einleitung

The fan in this laptop prevents the computer from overheating. It provides good airflow into the computer and out through the vents. Any clogging or damage could cause other problems in your computer.

Werkzeuge

Schritt 1

Close the display and turn over the computer.
Make sure your device is powered down and unplugged before beginning the replacement.

Schritt 2

Use a J0 bit tipped screwdriver to unscrew the one 6 mm Phillips screw on the RAM cover.

Schritt 3

Lightly lift the RAM cover up and at an angle, away from the computer.

Schritt 4

Use your fingers to carefully pull the securing clips on the RAM away from each other.
The RAM should pop up when the clips are released.

Schritt 5

Remove the popped up RAM by pulling it away from the connection.
If it does not pop up pry it out in a steady and straight direction.

Schritt 6

Slide the CD/DVD drive on the side of the laptop out using your fingers.
Using a J0 bit screwdriver, unscrew the one 2 mm Phillips screw.
You only need to unscrew this screw if you are using this as a prerequisite guide.

Schritt 7

Lift the plastic yellow flap on the system board.
Use the J0 Bit screwdriver to remove the one 6 mm Phillips screw in center of the system board that is connected to the keyboard.

Schritt 8

Flip over the computer and open the display.

Schritt 9

Insert a spudger next to the plastic indents located at the top of the keyboard and gently pry to release the securing clips.
Lift the keyboard off of the computer.
Be careful not to tear the ribbon that attaches the back of the keyboard to the computer when lifting it.

Schritt 10

Flip the keyboard over onto the palm-rest assembly.

Schritt 11

Flip the little black securing bar near the base of the ribbon with a spudger to release the ribbon from the computer.

This description is incorrect. I juist ruïned the keyboard connector. In my laptop there is no black securing bar. Instead, the white connector from the keyboard needs to come out of the black one on the motherboard. This is done horizontally.

Hurrah, just used these instructions to replace my fan and have a beautifully silent working laptop again - thanks! I skipped steps 20-23, and it would have been useful to have a mention that thermal compound was necessary to make a good connection when replacing the heat sink - but all in all great clear instructions. One happy good-as-new laptop owner!

This guide was bloody marvellous! This was the first time I’ve opened a laptop by myself and it was quite a ride but a fun one the only struggle that I had was the bloody blue ribbon connecting to the motherboard other than that the rest was really easy to follow. Thank you so much for the guide and I hope I can some day be a contributor just as great as you random internet person ^^
