Laptopas are very sensitive device and need more care than the desktops computers. Cleaning your Toshiba Satellite M45 hardware will help your laptop run more smoothly and minimize wear and tear on your system. Dust, pet hair, dander, food crumbs and residue from liquids such as coffee and soda find their way into your computer and settle onto internal components and into your keyboard. This dust and residue also builds up on your display screen and clogs vents. To keep your laptop in excellent working order, it is recommended that you regularly perform routine cleaning tasks outlined in this guide.
1: Cleaning Internal Fans
Clean internal fans once a year to prevent damage to the CPU’s circuitry. If your fans are not fully operational you’re the fine silicone circuits can melt in your CPU.
To clean these fans inside your laptop:
1. Gather the following supplies: #1 screwdriver (found in a small screwdriver set), cotton swabs, and isopropyl alcohol.
2. Shut down and unplug your laptop.
3. With the lid closed, turn your laptop upside down. Push the two tabs towards the outside edges of your laptop (see picture). Remove the long rectangular-shaped plastic battery cover
underneath your laptop near the screen hinge. While tabs are pulled, slide the plastic battery cover away from the hinge and pull it off. Unhook and remove the battery.
4. Remove 14 screws located around the base of your laptop. These screws are set down inside holes on the backing.
5. Then, remove the 3 screws from the component panels. (Be sure to store these small screws safely.) Pull the backing off carefully.
6. Remove small screws holding fans in place with the screwdriver.
7. Use several cotton swabs moistened with isopropyl alcohol to remove dust thoroughly from both fans.
8. Place fans back in place and twist screws back in with screwdriver.

2: Washing Down Heat Sinks
The Toshiba Satellite M45 has two heat sinks. Cleaning dust accumulation on your heat sinks once a year will improve the heat transfer process, keeping your laptop cooler.
1. If the battery is not removed and backing is still attached, follow steps 1 to 3 from Section 1: Cleaning Internal Fans.
2. Remove the heat sink attached to the CPU. Clean it with a cotton swab moistened with isopropyl alcohol. Cleansers other than isopropyl alcohol may leave a residue.
3. If your CPU is attached to the heat sink, the thermal grease might have dried out. Thermal grease made of silicone or metal based grease is applied to the base of heat sinks to help
conduct heat from the microprocessor and the heat sink. Use a flathead screwdriver to carefully pry the CPU and heat sink apart. Place the CPU back into the socket on the motherboard.

4. Remove old thermal grease from the heat sink bottom using cotton swabs moistened with isopropyl alcohol. Then, apply a new layer of thermal grease.
5. Place clean heat sink on top of chip. Repeat steps 1 to 3 with second heat sink.
3: Blowing Vents and Ports
There are two vents on the bottom of your laptop and one on the left hand side which allow air to enter the internal cooling system. Several physical network ports located on the sides of your laptop allow cables to connect to computers, routers, modems and other peripheral devices. Cleaning vents on your Toshiba Satellite M45 every six months helps your laptop’s cooling system work efficiently. Also, cleaning its ports every six months helps external
devices run properly.
1. If battery is not removed and backing is still attached, follow steps 1 to 3 from section 1: Cleaning Internal Fans.
2. While plastic backing is still removed from your laptop, blow both sides of vents with compressed air. Make sure the surface area you are working on is clean so debris does not blow into your ports. Keep air can upright to prevent liquid from accidentally leaking out of can. This, or any, liquid can damage components inside your laptop.
3. Use tweezers to remove any debris from your ports. Then blow compressed air into ports.
Ports include:
§ Right side: two USB and one i.link IEEE-1394
§ Back side: RJ11, RJ45, and S-Video
Do Not Use Your Laptop on Soft Surfaces. If you use your laptop in bed place your laptop on
a hard surface. The soft mattress, pillows and sheets will prevent heat from escaping out of the
sides and bottom of your machine. Overheating can cause permanent damage to the silicon chips in your computer.

4: Maintaining the Keyboard
Cleaning your Toshiba Satellite M45 keyboard weekly will reduce debris buildup and extend the life of your keyboard.
1. Turn off computer.
2. Turn laptop upside down and gently tap edge of case.
3. Using a keyboard brush with long fibers (often found at office supply stores), pass brush gently across the tops of keys, pushing dust and debris over the edge of your laptop.
4. Hold brush in vertical position. Pull brush between rows of keys from left to right, pushing dust and debris out from between keys and over the edge of your laptop.
5. Wipe tops of keys gently with moist cloth. Do not spray liquid directly on keys.

5: Wiping the Display
The technology of your LCD screen is extremely delicate. Cleaning your laptop display takes little effort, however, if done incorrectly can cause great damage. Wipe your display weekly.
1. Moisten a lint-free cloth with a spray bottle filled with distilled water. Do not spray liquid directly on screen.
Important: Tap water is filled with minerals that can streak your screen. If distilled water is not solvent enough to clean your screen, mix a solution of half distilled water and half vinegar. Do
not use solutions containing Acetone, ethyl alcohol, toluene, ethyl acid, ammonia, or methyl chloride on your LCD screen.
2. Wipe display in a repetitive motion either top to bottom or side to side.
