Problems with overheating and sudden shutdowns are familiar to many laptop computer owners, especially those who have been using them for several years without maintenance. Laptops Acer are famous for their performance, but their cooling systems are often clogged with dust, which leads to a decrease in processor frequency and noisy fans. Ignoring this process may result in the failure of expensive components such as a video chip or motherboard.
Regular cleaning is not just a whim, but a necessity to maintain stable operation of the device. If you notice that the case is hot to the touch, and applications are sluggish even under minimal load, then it's time for some maintenance. In this article, we will look at how to safely disassemble the device, remove accumulated debris and return the cooling system to its former efficiency.
Preparing the workplace and necessary tools
Before you begin disassembly, it is extremely important to create a safe space to work in. You'll need a clean desk with a hard surface, good lighting, and no drafts to prevent fine dust from settling on exposed components.
The most important stage is preparing the tools. You don't have to buy a professional kit, but there are some specific items you should have on hand. For a successful procedure, you will need a Phillips screwdriver with a thin blade, a plastic card or a special mediator paddle, a can of compressed air and isopropyl alcohol.
- 🔧 Phillips screwdriver (PH0 or PH00) - for unscrewing the screws on the bottom cover
- 💨 A can of compressed air - for blowing dust out of hard-to-reach places
- 🧼 Isopropyl alcohol (90%+) - for degreasing contacts and removing old thermal paste
- 🧽 Cotton swabs and lint-free cloth - for careful cleaning of the radiator
- 🧴 New thermal paste - for example, Arctic MX-4 or Thermal Grizzly to replace
Don't forget to also prepare a container for the screws so you don't lose them while working. It is best to use a magnetic mat or divide the screws into groups on a piece of paper, labeling which one was located.
Safe disconnection and removal of external cover
The first and most critical step is to completely de-energize the device. Turn off the laptop through the menu Start → Shutdown, and then disconnect the network adapter and all connected peripherals such as mouse, flash drives or external monitors.
The next step is to remove the battery, if its design allows this to be done without disassembling the case. In models Acer Aspire or Extensa older generations often do this with one movement of the latches. If the battery is built-in, as in the series Acer Swift or Aspire 5, you will have to immediately begin removing the bottom cover.
- 🔋 Disconnect the battery cable from the motherboard immediately after opening
- 🔩 Carefully unscrew all the screws on the bottom panel without using excessive force
- 🪜 Use a plastic spatula to pry out the latches around the perimeter of the lid
Be extremely careful when handling latches. The fragile plastic of the case can crack if touched carelessly. Move slowly around the perimeter and do not push down on the cover until you are sure that all the latches have clicked into place.
⚠️ Attention: Never try to remove the bottom cover by force if it does not give way. Chances are you've missed one of the hidden screws, often located under rubber feet or stickers.

Primary cleaning of the cooling system without disassembly
Sometimes simply venting the outside of the radiator is enough to improve the situation, especially if the laptop has been used recently. This method avoids the risk of damaging cables or connectors when completely disassembling the case.
You need to direct a stream of compressed air at an angle into the vents. Do this in short bursts so that the dust does not get deeper, but flies out. It is advisable to fix the fan blades so that they do not unwind from the air flow, which can damage the bearing.
- ❄️ Keep the container vertical to prevent drops of condensation from flying out
- 🔄 Secure the fan blades with a toothpick or finger before blowing
- 🌬️ Blow through the grilles on both sides: from the back and through the ventilation slots
This method is effective for removing the surface layer of dust, but it will not replace a thorough cleaning of the radiator if it is clogged with “felt” of dirt.
What to do if you don’t have a compressed air cylinder?
You can use a regular vacuum cleaner, but at minimum power. However, it is better to use a special hand pump or even a hair dryer in cold air mode, keeping at a safe distance so as not to overheat the plastic case with static electricity.
Complete disassembly and deep dust removal
If simple blowing does not help, you will have to disassemble the laptop to the ground. This is a difficult stage that requires patience and accuracy. Remove the bottom cover and disconnect the cables leading to the keyboard, touchpad and display if they interfere with access to the cooling system.
Cooling system in laptops Acer usually consists of copper tubes passing through a radiator with metal plates. Dust accumulates here between the plates in a dense layer, blocking the air flow. You need to carefully remove this layer using a soft brush and tweezers.
- 🧹Use a soft brush to sweep away dust from the radiator
- 🔍 Inspect the fans for dirt accumulation on the blades
- 🧼 Wipe the fan blades with a cotton swab dipped in alcohol
Pay special attention to the place where the copper tubes enter the radiator. This is often where the most dust accumulates. Clean these channels with compressed air, directing the jet at different angles.
☑️ Deep cleaning tools
Replacement of thermal paste and re-installation
After removing the dust, it is necessary to replace the thermal paste, since the old one loses its properties over time and ceases to effectively remove heat. This is a critical step to restore the temperature of the processor and video card.
First, thoroughly clean the surface of the processor and video card chip from any remaining old paste. Use isopropyl alcohol and a lint-free cloth or Q-tip. The surface should become perfectly clean and shiny.
⚠️ Warning: Do not use acetone or solvents to clean the processor, as they may damage the protective coating on the chip or the plastic casing around it.
Apply new thermal paste to the center of the processor. For modern chips, the "dot" or "line" method is best, but do not smear it with your finger if you are not sure of the uniformity of the layer. Excess paste may leak outside the crystal and onto the contacts.
If the thermal paste has dried out and turned to stone, do not scrape it off with a metal tool. It is better to wipe the surface with an alcohol wipe several times to soften and remove any residue.
Reinstall the radiator, following the order in which the screws were tightened. They are usually marked with numbers (1, 2, 3), which indicate the sequence of tightening for even pressure. Tighten the screws crosswise, gradually increasing the force.
Test measurements and performance checks
After assembling the laptop, do not rush to load heavy games right away. First, turn on the device and check if there is any strange noise from the fans. Make sure the keyboard and touchpad are working correctly and the display is free of artifacts.
To check the effectiveness of cleaning, use special monitoring utilities. Run the program AIDA64 or HWMonitor and monitor temperatures at idle and under load.
- 🌡️ Idle CPU temperature Acer should be in the range of 35-45°C
- 🔥 Under load, the permissible limit is 80-85°C for modern chips
- 📉 If the temperature is higher, the thermal paste may be applied incorrectly or the heatsink is not pressed down
| Parameter | Value before cleaning | Value after cleaning |
| :--- | :--- | :--- |
| Idle temperature | 75°C | 42°C |
| Temperature under load | 98°C | 72°C |
| Fan noise | Unpleasant hum | Quiet rustling |
| CPU frequency | Reduced (throttling) | Stable |
| Battery life | Reduced | Normal |
Regularly replacing thermal paste every 2-3 years will keep your laptop's performance at factory specifications and extend the life of your components by years.
Common mistakes when servicing laptops
Many users make mistakes that can lead to device malfunction. One of the most common is using a household vacuum cleaner without grounding. Static electricity from a vacuum cleaner hose can instantly destroy the motherboard.
Another mistake is using water or wet wipes to clean electronics. Even a small amount of moisture can cause a short circuit. Always use isopropyl alcohol, which evaporates quickly and is non-conductive.
⚠️ Attention: If you are not confident in your abilities or are afraid of damaging the device, it is better to entrust the cleaning to professionals. The cost of the service is often lower than repairing after an unsuccessful attempt on your own.
Don't forget about regular preventive maintenance. Do not place the laptop on soft surfaces such as blankets or sofas, as this will block the air intake. Use special ventilated stands to improve air circulation.
How often should you clean your laptop?
The frequency of maintenance depends on operating conditions. If the laptop is used in a dusty room or there are animals at home, cleaning should be done once every 6 months. Under normal conditions, once a year is sufficient.
