The main thing is to follow the instructions and take your time. And for those who are planning not only cleaning, but also an upgrade, we have prepared a component compatibility table.
What tools are needed for disassembly?
Before you start disassembling, prepare everything you need. Failure to use the correct tools can result in loose screws, scratches on the case, or even damage to internal components. Here minimum setwhich will be required:
- 🔧 Phillips screwdriver (preferably magnetic, size PH0 or PH1) - for most case screws and internal fasteners.
- 🔨 Plastic pick or guitar pick - for carefully prying off the lid latches.
- 🧲 Magnetic mat or container - so as not to lose small screws (they are in ASUS K52J about 20 pieces!).
- 🖌️ Thin flathead screwdriver (1.5–2 mm) - for disconnecting cables and connectors.
- 🧴 Thermal paste (For example, Arctic MX-4 or Noctua NT-H1) - if you plan to replace it.
- 🧹 Soft bristle brush And compressed air can - for cleaning the radiator and fan.
- 🔌 Antistatic wrist strap (optional) - to protect components from static electricity.
If you are planning replacing thermal paste, prepare additionally isopropyl alcohol (90%+) and lint-free wipes for cleaning the old layer. To disassemble the cooling system you may need hexagon 2.5 mm - Use it to unscrew the screws securing the radiator to the motherboard.
⚠️ Attention: Do not use metal screwdrivers to pry plastic latches! This will lead to chips and cracks. A plastic pick or a special spatula for disassembling electronics is a must-have tool.

Preparing a laptop for disassembly: important steps
Before you take a screwdriver, you need to properly prepare your laptop. This will save you from unpleasant surprises like short circuits or data loss.
Turn off the laptop and disconnect the power supply
Remove the battery (press the latch at the bottom of the case)
Disconnect all peripheral devices (mouse, flash drives, external drives)
Make a backup copy of important data (in case of errors during assembly)
Prepare your workplace: flat surface, good lighting -->
Pay special attention battery. B ASUS K52J it is attached with one latch, but many users forget what is hidden under it one of the back cover screws. If you do not unscrew it first, the plastic may crack when you try to remove the cover.
We also recommend take a photo of the location of the screws before unscrewing them. B ASUS K52J Screws of different lengths are used (for example, to secure the motherboard and hard drive), and mixing them up during assembly is a common mistake that leads to component damage.
⚠️ Attention: If you are disassembling a laptop for replacing thermal paste, let it cool for at least 30 minutes after turning it off. Working with a hot radiator is not only inconvenient, but also dangerous - you can get burned.
Step-by-step disassembly of the ASUS K52J case
Now let's move on to the process itself. Disassembly ASUS K52J consists of several stages, and we will analyze each of them with photographs and comments.
1. Removing the back cover
Let's start by unscrewing all the screws on the bottom of the case. B ASUS K52J them 11 pieces (not counting the screw under the battery!):
- 🔹 9 screws around the perimeter (length ~5 mm).
- 🔹 1 screw under the battery (length ~3 mm).
- 🔹 1 screw in the hard drive compartment (length ~7 mm).
Once all the screws are removed, carefully pry the cover with a plastic pick, starting at the corner next to RAM compartment. The latches are quite fragile, so do not use excessive force. If the cover does not budge, check that all screws have been removed.
What to do if the cover does not come off?
If the lid does not open after removing all the screws, you may have missed one of them. Most often people forget about the screw under the battery or in the hard drive bay. Also check that the cover does not cling to the cables - sometimes they are glued to the body with tape.
2. Removing components
After removing the cover, you will see the insides of the laptop. B ASUS K52J The components are arranged as follows:
| Component | Location | Extraction Features |
|---|---|---|
| Random access memory (RAM) | Upper left corner (under cover) | Press the latches on the sides of the module |
| Hard drive (HDD/SSD) | Center of the case (in the metal compartment) | Unscrew the 4 screws, pull the tab |
| Wi-Fi module | Upper right corner (under the black cover) | Disconnect antennas, unscrew 1 screw |
| Cooler and radiator | Lower left corner (under the copper tube) | You need to unscrew 4 hex screws |
When extracting hard drive Pay attention to the rubber gaskets in the compartment - they often stick to the case and get lost. Without them, the disk will rattle during assembly.
RAM can be removed without tools - just press out the latches on the sides of the module. B ASUS K52J usually installed strips DDR3 SO-DIMM with a maximum capacity of up to 8 GB (2×4 GB).
If you are planning to upgrade your RAM, check the compatibility according to your motherboard model. B ASUS K52J a fee was often set K52JC or K52JR, which support memory up to 1600 MHz.
3. Disassembling the cooling system
To access the fan and radiator you must:
- Disconnect the cooler cable from the motherboard (carefully pry the connector with a flat-head screwdriver).
- Unscrew the 4 hexagon screws (they may be under seals - do not damage them if the laptop is under warranty!).
- Remove the radiator by rocking it from side to side (the thermal paste may “stick”).
Clean the radiator and fan can of compressed air, holding the cooler blades so that they do not rotate due to the air flow (this can damage the bearing). To remove old thermal paste, use isopropyl alcohol and lint-free wipes.
Do not use sharp objects (knives, screwdrivers) to clean the radiator - this can damage the cooling fins and reduce the efficiency of heat dissipation.
Replacing thermal paste on ASUS K52J: nuances
One of the most common reasons for disassembly ASUS K52J is replacing thermal paste. Over time, it dries out, which leads to overheating of the processor and video card (in models with discrete graphics). Here's how to do it right:
1. Removing old paste: Apply a little isopropyl alcohol to a tissue and gently wipe off the old layer from the processor and graphics chip (if equipped). Do not rub too hard as this may damage the crystals.
2. Applying new paste:
- For processor (Intel Core i3/i5) enough peas 4–5 mm.
- For video card (NVIDIA GeForce 310M or ATI Radeon HD 5470) - a thin layer spread with a spatula.
- Avoid excess paste - this may cause it to get on the contacts.
3. Cooling system assembly: Before installing the heatsink, make sure the thermal paste is evenly distributed. Tighten the screws criss-crossto avoid skew.
After assembly, turn on the laptop and check the temperatures in the program HWMonitor or AIDA64. Normally, under load, the processor should not heat up above 75–80°C. If the temperature is higher, the thermal paste may have been applied incorrectly or the heatsink may not fit well.
Cleaning your laptop from dust: a step-by-step process
Dust is the main enemy of any laptop. B ASUS K52J it accumulates not only on the radiator, but also in ventilation ducts, which impairs cooling. Here's how to clean as efficiently as possible:
1. Cleaning the fan:
- Secure the blades (for example with a toothpick) so that they do not rotate.
- Blow with a can of compressed air, holding it at a distance of 5–7 cm.
- Use a brush to remove adhered dust.
2. Radiator cleaning:
- Blow the radiator fins lengthwise (not across!) so as not to bend them.
- If the dust is stuck tightly, soak a brush in isopropyl alcohol and carefully clean the cracks.
3. Cleaning the keyboard and case:
- Turn the laptop over and shake it until large particles of debris fall out.
- Go over the keys with a vacuum cleaner at minimum power (or a spray can).
⚠️ Attention: Do not use the vacuum cleaner at full power for cleaning - this may damage the fan or tear off small components from the motherboard. Also avoid using wet wipes to clean internal parts as this may cause a short circuit.
After cleaning, we recommend checking the operation of the fan. Turn on the laptop and listen for any extraneous noise (creaks, rattles). If the cooler does not start, check the connection of its cable to the motherboard.
Typical mistakes when disassembling ASUS K52J and how to avoid them
Even experienced users sometimes make mistakes that lead to breakdowns. Here are the most common ones when working with ASUS K52J:
- 🔧 Screw failure - occurs due to the use of an unsuitable screwdriver. Always make sure that the screwdriver blade fits snugly into the screw slot.
- 💥 Broken plastic latches — most often the clips break around
RAM compartment. Pry up the cover carefully, without jerking. - 🔌 Damage to cables — the Wi-Fi module and webcam cables are very fragile. Pull only on the connector, not on the wires!
- 🔥 Overheating after assembly — if you forgot to connect the cooler or applied thermal paste incorrectly, the laptop will overheat.
- 🖥️ Screen not working — if after assembly the image does not appear, check the connection of the matrix cable (it is located under the keyboard).
Another common problem is loss of screws. B ASUS K52J there are many of them, and they are of different lengths. To avoid confusion, place them in groups or label the containers. For example:
- Short (3 mm) - for attaching the lid.
- Medium (5 mm) - for the hard drive and Wi-Fi module.
- Long (7 mm) - for the radiator and motherboard.
If the laptop does not turn on after assembly, do not panic. Check:
- Connecting the battery and power supply.
- Attaching RAM (sometimes modules are not fully inserted into the slots).
- Connecting the keyboard cable (if you disassembled it).
Upgrade ASUS K52J: what can be improved
ASUS K52J - a laptop with limited upgrade capabilities, but some components can still be replaced. Here's what you can really improve:
| Component | Maximum configuration | Performance boost |
|---|---|---|
| RAM | 2x4 GB DDR3 1600 MHz | Improving multitasking, working with heavy programs |
| Hard drive | SSD 2.5" (SATA III, up to 1 TB) | Speed up system and program loading by 3–5 times |
| Wi-Fi module | Intel 7260 (dual-band, up to 867 Mbit/s) | More stable signal and high internet speed |
| Battery | Original or analogue (6 cells, 4400 mAh) | Restoring battery life |
The most noticeable upgrade is replacing HDD with SSD. Even budget Samsung 860 EVO or Crucial MX500 will turn the laptop into a “rocket” compared to the original hard drive. In this case, you do not need to reinstall Windows - just clone the system using Macrium Reflect or Clonezilla.
If your model has discrete graphics (NVIDIA GeForce 310M or ATI Radeon HD 5470), then upgrading the video card is impossible - it is soldered into the motherboard. However, you can improve cooling by installing copper spacers to the graphics chip when replacing thermal paste.
Before purchasing an SSD, check the height of your HDD case. B ASUS K52J Usually drives with a height of 9.5 mm were installed, but some SSDs have a height of 7 mm. In this case, you will need an adapter or gasket to secure it tightly.
