Toshiba Satellite C855D-S5303 Fan Replacement

Lay your laptop upside down on a flat surface.

Power off your laptop and unplug the charger.

Locate the right eject switch, labeled "1".

Slide the switch all the way to the right and it should stay in place.

The second eject switch is on the left and it is numbered "2".

Slide the switch to the left and remain pushing on it, because unlike switch "1" it will not stay in place on it's own.

With hand still pushing the left switch, grab onto notch at the center of the two switches.

Pull up and towards you. The battery will begin to lift out of the device.

The battery can now be pulled out entirely. You are ready to replace it.

Using a small Phillip's head screwdriver, unscrew the single 7 mm screw (5 mm head) on the L-shaped panel on the backside of the laptop.

Once the screw is removed, pry the panel upwards by gripping the groove pictured.

Locate the hard drive. It is in a metal casing as pictured.

To remove, grab the right side of the piece and slide leftwards.

Lift up and out.

Now that you have your battery and hard drive removed, it's time to begin unscrewing the back panel.

Taking a Phillip's head screwdriver, remove the two 7 mm (5 mm head) screws located around the spot where the hard drive once was.

There are nine 7 mm (5 mm head) screws located around the perimeter of the laptops back panel. Unscrew them all.

Get a grip on one edge of the back panel that is now unscrewed and lift its entirety up and away from the device.

To remove the fan, unscrew the two 4 mm (3 mm head) screws that are around the fan.

Unplug the wire located to the left of the fan by pulling gently upwards.

Now that the fan is unplugged, you can lift it up and out of the device.
