How do I clean my laptop?
Unfortunately, unlike a desktop computer, a laptop is not as easy to open and clean. However, there are still several steps an end-user can do to clean and maintain their laptop or portable device.
Before cleaning a laptop, we suggest the laptop first be turned off and unplugged. Also, because you are going to be cleaning the laptop, we also suggest you remove the battery.
Cleaning a laptop case
Cleaning the exterior portion of the laptop case can help keep the laptop looking new. The exterior case of a laptop can be cleaned by using a cotton cloth that has been dampened with water. It is not recommended that the exterior case of the laptop be cleaned with household cleaning solutions. However, if there is a substance on the laptop that cannot be cleaned with water, we suggest using rubbing alcohol.
Cleaning case openings
If dust, dirt, hair, or other substances are in the case openings, it can prevent airflow, which can cause the laptop to overheat and may even cause it to reboot unexpectedly.
Look for laptop openings where the laptop draws in cool air from outside or blows out any hot air from the inside of the laptop. These openings are usually on one of the sides, the back, or the bottom of the laptop. Dust, dirt, hair, or other substances can almost always be removed using a cotton swab or compressed air.
Caution: If you are using compressed air to clean the openings that have fans in them, the amount of air blown on the fans can cause them to spin too fast, damaging or destroying the fan. To help prevent this issue, place something in-between the fan blades, such as a toothpick, to keep the fan from spinning why blowing compressed air at and through the fan and air ducts.
Cleaning a laptop keyboard
Like almost everything else on a laptop, a keyboard is also different from the standard computer keyboard. With many laptop keyboards, the keys cannot be completely removed. Therefore, we suggest cleaning the keyboard by using the same damp cloth you used to clean the exterior case of the laptop. Also, compressed air can be used to blow out any dust, dirt, hair, or other substances from in-between and underneath the keys.
If you have spilled something onto the laptop keyboard that is causing the keys to stick and cleaning it does not help, we suggest that you have the laptop professionally serviced.
Cleaning a laptop mouse (touchpad)
Cleaning the laptop touchpad can help improve the look of the laptop, and it also may help to improve the responsiveness of the touchpad. To clean the touchpad surface, use the same damp cloth used to clean the exterior of the laptop.

Cleaning internal laptop components
Cleaning the inside of a laptop computer can be a difficult task. However, in some situations, it may be necessary because of excessive dust and dirt buildup in the laptop, such as on the processor's heat sink.
Disassembling a laptop is much more complicated than disassembling a desktop computer. Because of the small form factor, it is much more difficult. Instructions for disassembling a laptop depend on the laptop model and brand. Because there are so many different brands and models of laptops, we cannot provide information on how to disassemble every laptop. If after performing the cleaning steps listed above, you still believe the laptop is overheating because of dust or dirt, we suggest taking the laptop to an authorized repair center.
If you still prefer to disassemble the laptop and clean it yourself, you need to find instructions for doing so from the manufacturer, if available, or by searching on the Internet.
Note: The manufacturer's warranty may be voided if you disassemble the laptop yourself.
