Cleaning a laptop at home. Step-by-step instruction!

Hello friends! Today we will touch on an issue that interests many, and we will tell you how to completely clean your laptop from dust at home so that it does not slow down. This is done quite simply and often the device does not even have to be disassembled. Well, without delay, let's get started.

Cleaning your laptop or netbook from dust is very important. If you do not do this for a long time, the device may simply fail, and without the possibility of recovery.

How to tell if your laptop needs cleaning

You can understand the fact that it’s time to clean your laptop from dirt by the following signs:

the device gets very hot;
when turned on, a strange growing noise is heard;
the fan works, but does not cope with its task;
programs freeze when running;
there is sticking of buttons;
The device takes a long time to turn on;
In some cases, when the laptop overheats, it turns off on its own.

All these signs indicate that the hour has come, and the laptop requires cleaning.

Assembly

I think it’s clear and so - everything is in reverse order...

Among the nuances - special attention should be paid to fixing the matrix cables (after assembly, the screen backlight may not work) and the hard drive cables - otherwise you will get a non-working “machine”. The keyboard cable is not very easy to insert and is fragile - be careful.

We put it together and turn it on :)))… and it’s a bummer!
It seems to work - but there is no control of the cooling fan! Constant loud noise from the fan running at full speed.

I rummaged through the forums (there are nuances of settings in the BIOS and the system, and I managed to climb a lot of places when the cooling was not working well) and in reviews of the product (where the cooler was purchased). From the reviews I realized that the purchased cooler, although 4-wire, is a fake! This option does not have rotation speed control—you didn’t have to buy “that.” The original worked quite well, with the controller disabled. CONCLUSION: You need to read reviews FIRST, and only then make a purchasing decision!

I waited a day or two, and went to look for another cooler. Found. And I’ve already changed the link to the second cooler I bought - here, judging by the reviews, everything should be fine with the speed control...

All three coolers in a row

and yes, the newly purchased one has speed control!

In total we have: Three complete disassembly/assembly of the laptop (the first time I looked at the cooler markings) - as best I could, I showed that disassembly was a “so-so” pleasure. Well, a completely working laptop cooling system!

Good luck and good mood to everyone!

Existing types of laptop cleaning

Ways to clean your laptop from dust:

Superficial - external cleaning of the laptop: case, screen, blowing dust from the outside through the fan holes. All this is a preventive measure not only for the device, but also for the health of the owner, since dust is extremely dangerous to health.
Deep - complete disassembly of the device, cleaning every part from dirt.

Tools required for cleaning

Vacuum cleaner/hair dryer for sucking up dust.
Compressed air cylinder. It is similar in type to a hair dryer.
Soft brushes and thin brushes for cleaning the keyboard and other small crevices.
Cotton swabs and disks.
Microfiber cloth for cleaning.
A set of Phillips screwdrivers of various diameters for disassembly.

But for the “general wash”, you need to prepare:

Machine oil to lubricate the cooler.
For wiping microcircuits, use isopropyl alcohol.
Thermal paste for cooling the device.

Features of different models

It is worth considering that there are a large number of different laptop models on the market, which may turn out to be specific and require special attention. After all, each laptop, depending on the brand, may have a complete structure or a unique arrangement of component parts, which can either have a beneficial effect on the cleaning process or hinder it. For example, Asus and Acer are trying to create laptops in such a way that they are convenient to service not only for service centers, but also for ordinary users.

And if we take Sony, HP or Samsung as an example, sometimes special skills may be required to clean such laptops. At the same time, the company itself does not seek to complicate everything, because the main point is the efficiency of using technology.

How to clean your laptop from dust without disassembling it

Superficially cleaning a laptop from dust at home is a fairly simple procedure. At the bottom there is a ventilation inlet grille - an opening for air to enter the cooling system. From the fan blades, the cooled air passes further to the video card and processor, lowering their temperature. At the end there is a fan grille through which heated air is blown out of the equipment. If you do the cleaning yourself, it is better to do it with an emphasis on the fan grilles, since a lot of household debris gets in there. Using a vacuum cleaner, you can remove small particles of dirt from the depths of the grate. How to do this as efficiently as possible?

Disconnect the device from the network.
Place it edge-on, like an open book.
Remove the attachment from your household vacuum cleaner.
Bring the tube of the switched on dust fighter to the grille and hold it there for 2-3 minutes.
It is more convenient to clean the entrance to the ventilation with a can of compressed air. It is sold freely in any construction and technical market. The elongated aerosol nozzle is easily inserted into the ventilation compartments. When pressed, air comes out of the spout, which rotates the fan blades and removes dust from it. This is done like this:
Turn the equipment over and blow out all the crumbs between the keyboard buttons with a balloon.
Place the laptop on its edge and clean the ventilation outlet.
Return to normal position and blow through the entrance.

This is a method for non-professionals, and experts recommend carrying out such preventive cleaning quite often - once every 2-3 months. This will improve the performance of the laptop and extend its service life.

Do-it-yourself comprehensive laptop cleaning

If simple methods do not help or the equipment has not been cleaned for several years, a comprehensive cleaning will be required with disassembly of the entire case.

Removing the back cover

The first step is to open the laptop to get to the contaminated parts. To do this, unscrew the bolts holding the panel at the back using a Phillips screwdriver of the required diameter. Twist them counterclockwise. On some models, only the portion of the panel above the vent is removed, rather than the entire cover. Collect the unscrewed bolts in a container so as not to lose them. If the cover does not budge, do not force it, but double-check that all the bolts have been removed. After removing the cover, wipe it outside and inside.

Radiator and cooler

First of all, find the cooler and radiator. The cooler looks like a fan in a square or round frame, and the radiator is a box with a grille. They can be blown out with a vacuum cleaner or a spray can, and dust from the microcircuits should also be blown out. But you need to use the vacuum cleaner very carefully so as not to damage fragile parts. The handset must not be brought close to or touch the circuits.
Unscrew the screws that hold the fan in place and put it somewhere else. Remove the fan, disconnect the cable leading to the microcircuit. Wipe the blades with a brush and blow air through the area where the cooler was located.
For prevention, lubricate the engine with machine oil by dropping a drop inside. Return the device to its place, attach the cable and tighten the bolts.
Thoroughly clean the radiator with a thin brush to remove old thermal paste and dust accumulations.

Video card and motherboard

The motherboard is the most fragile part of a laptop, so you need to remove it very carefully. Walk over the surface with a soft brush slightly moistened with alcohol and blow off the microcircuits and contacts.
Remove the processor from the slot as carefully as possible. Pull the socket pedal (the connector where the processor is inserted) slightly to the side and lift it up. The pedal should be vertical, then grab the processor by the sides and remove it from the connector. Go over the contacts with a cotton swab dipped in alcohol.

Replacing thermal paste

Cleaning the ventilation system involves changing the thermal paste. Remove any leftovers. If it's dry, rub it with an alcohol wipe. Be careful, there should be no scratches. Apply the paste a little at a time, spreading it with your finger or spatula (included) over the radiator plate.

Cleaning the keyboard

The keyboard is perhaps the dirtiest place on the computer. If it is not very dirty, wipe it from the outside with special napkins for equipment or a cloth soaked in a soapy solution. Wring out the cloth, soap the buttons, rub to remove dirt and soap, and wipe dry. It is important not to damage the markings or flood the keys.

Cleaning the connectors

Internet or USB ports can also become dirty. This periodically causes problems with connecting flash drives, phones and mice. Take a brush with long bristles. If the hole is narrow, then simply cut a strip of plastic along the width of the slot and cover it with double-sided tape. Dip the Velcro in alcohol and let it dry thoroughly. Lightly wipe the ports and blow them with compressed air.

Screen care

The monitor should not be rubbed with compounds that contain alcohol, as moisture may damage the screen. Buy alcohol-free wipes for LCD screens or a spray solution. Rub so that there are no streaks left. It is better to do a complete cleaning once a year.

Remove the battery

Turn off your computer. Slide the latch and disconnect the battery. This will save the components from static electricity. In addition, in almost all laptops the battery interferes with removing the cover and hides the mounting screws.

In some models, the non-removable battery is located under the cover. In this case, you need to disconnect the battery cable from the motherboard after removing the back panel.
