Disassemble the laptop DNS doing it yourself is a task that scares many users. The fear of damaging fragile components or losing the warranty often stops even experienced equipment owners. However, with the right approach, patience and a set of tools, the procedure becomes completely doable. In this article we will look in detail at how to safely dismantle the case, get to the internal components and avoid common mistakes.

Laptops DNS (especially popular models with diagonals 14.1", 15.6" And 17.3") have a standard design, but some nuances depend on the specific series. For example, in the line DNS Prestigio case mounts may differ from budget models DNS Ultrabook. We will take these features into account and give universal recommendations applicable to most brand devices.

Before you begin, make sure you have a good reason for disassembling: dust cleaning, replacing thermal paste, RAM or SSD upgrade, or keyboard/screen repair. If the goal is simple curiosity, it is better to refrain: each disassembly increases the risk of damage to the cables or contacts.

Preparing for Disassembly: Tools and Safety Precautions

The first step is collecting the necessary equipment. Without the right tools, you risk stripping screws, damaging plastic latches, or scratching the case. Here is the minimum set you will need:

  • 🔧 Screwdriver set: cross (PH0, PH1) and flat (SL2.0) for housing screws, as well as a five-pointed (Pentalobe P5) - it is often used in laptops DNS for attaching the bottom cover.
  • 🧲 Magnetic mat or tray for screws: to avoid losing small parts and keep them organized (for example, the keyboard and case screws often differ in length!).
  • 📸 Smartphone for photography: record each stage of disassembly, especially the location of cables and connectors. This will save you during reassembly.
  • 🧴 Plastic picks or guitar picks: they will help you carefully pry the case latches without damaging them.
  • 🔌 Antistatic wrist strap (or at least regular grounding with your hands on a metal object): static electricity can damage the motherboard or SSD.

Before starting work completely unplug the laptop and remove the battery (if it is removable). If the battery is soldered, disconnect its cable from the motherboard first of all. This will prevent a short circuit from accidentally touching the contacts.

⚠️ Attention: Laptops DNS series Gaming (For example, DNS 15.6" GTX) often have additional metal screens over the radiators. Their screws may be hidden under stickers - don't forget to check! Tearing off such a sticker without heating it with a hairdryer will lead to traces of glue on the case.

Removing the Bottom Cover: Step by Step Process

Laptop bottom cover DNS secured with a combination of screws and plastic clips. Let's start with the screws:

  1. Turn the laptop over screen down on a soft surface (for example, a towel).
  2. Unscrew all visible screws along the perimeter. In models DNS 14.1" there are usually 8–10 of them, in 15.6" - up to 12. Pay attention to the screws near the screen hinges - they may be longer than the rest!
  3. If the screws are stuck, use WD-40 or rubber band for better grip of the screwdriver.
  4. After removing the screws, carefully pry the lid with a pick, starting from the corner near the touchpad. Move around the perimeter, releasing the latches one by one.

Do not use excessive force - if the cover does not budge, check that all screws are removed. In some models (for example, DNS Ultrabook 15) additional fasteners may be hidden under the rubber feet.

DNS 15.6" Gaming 12–14 PH1, Pentalobe P5 Additional screws under the stickers
DNS Ultrabook 13 6–8 PH0, T5 (asterisk) Magnetic lid + 2 latches

Access to internal components: what you can replace yourself

After removing the cover, you will see the insides of the laptop. In models DNS a typical layout includes:

  • 🖥️ Motherboard (usually under a metal screen).
  • 💾 SSD/M.2 drive (can be covered with a thermal pad).
  • 🧠 RAM (in budget models it is often soldered!).
  • 🔋 Battery (soldered in or on a ribbon cable).
  • 🌬️ Cooler and radiator (usually secured with 3-4 screws).

In 2022+ DNS series laptops, the RAM is often integrated into the motherboard (e.g. DNS Air 14). Before purchasing a new RAM module, check the specifications of your model on the manufacturer's website!

The easiest components to replace are:

  1. SSD: usually format M.2 2280 (For example, Kingston NV1 or WD Blue SN570). It is enough to unscrew one screw and remove the drive at an angle of 30°.
  2. RAM (if not soldered): press the latches on the sides of the slot and remove the strip.
  3. Wi-Fi module: a small board under a cover with antennas. B DNS often used Intel AX200 or Realtek RTL8852AE.
⚠️ Attention: When replacing SSD in laptops DNS with Optane Memory (For example, DNS 15.6" i5-1135G7) you need to disable the technology in the BIOS (Advanced → VMD Controller → Disabled), otherwise the new drive will not be detected.
💡

If you are changing thermal paste, use liquid metal (For example, Thermal Grizzly Conductonaut) only on copper bases of radiators. For aluminum, classic paste is suitable Arctic MX-6.

Disassembling the keyboard and touchpad: nuances and risks

Keyboard and touchpad in laptops DNS are attached to the top of the case and connected to the motherboard with cables. To remove them:

  1. Unscrew the screws under the cover (usually 3–5 pieces, marked as KB or KBD).
  2. Carefully lift the keyboard using a plastic spatula, starting at top edge (from the screen side). Don't pull the wires!
  3. Disconnect the keyboard cable by prying the black latch of the connector up (not sideways!).
  4. For the touchpad, repeat the process - its cable is usually located nearby, but shorter.

In models DNS Prestigio The keyboard can be glued with double-sided tape. In this case, warm up the case with a hairdryer (temperature no higher than 60°C) and carefully pry up the keys one at a time, starting with Space (the largest).

What to do if a key breaks off?

If the plastic key fastener is broken, you can order a new one on AliExpress (search by laptop model + “keyboard key”). For temporary repairs, use superglue Loctite 406 (does not leave marks) and a toothpick to secure the mount.

Please note keyboard backlight cable (if there is one) - it is thinner than the main one and breaks easily. B DNS Gaming the backlight is often controlled by a separate controller located under the touchpad.

Cleaning the cooling system: how not to damage the radiator

Cooler dust is the main reason laptops overheat DNS. To clean the cooling system:

  1. Unscrew the screws securing the cooler and radiator (usually 3-4 pieces, marked as FAN).
  2. Disconnect the fan power connector from the motherboard.
  3. Remove the radiator along with the cooler. Be careful - thermal paste may stick to the processor!
  4. Remove dust soft brush or vacuum cleaner at minimum power. Do not use wet wipes!
  5. Apply new thermal paste (a layer thick 0.1–0.3 mm) and reassemble everything in reverse order.

In laptops DNS with dual cooling system (For example, DNS 17.3" Ryzen 7) there may be two radiators: for the CPU and GPU. It is better to clean them one by one so as not to confuse the thermal pads.

Model Cooling type Number of fans Recommended thermal paste
DNS 15.6" i3-1005G1 Single radiator 1 Arctic MX-4
DNS Gaming RTX 3050 Dual heatsink + 2 heat pipes 2 Thermal Grizzly Kryonaut
DNS Ultrabook 14 Passive + active 1 (thin) Noctua NT-H1

Reassembly: how to avoid mistakes

Assembling a laptop DNS after disassembly it requires no less care. Follow these rules:

  • 🔄 Check all cables: They must be firmly inserted into the connectors until they click. This is especially true for the screen cable - its distortion will lead to artifacts on the display.
  • 🔩 Tighten the screws crosswiseto avoid body distortion. Start with the corner screws.
  • 📋 Check the photosmade during disassembly. For example, keyboard and case screws often differ in length by 1–2 mm.
  • 🔋 Connect the battery last (if it is removable). This will eliminate the risk of a short circuit if you accidentally touch the board.

After assembly don't turn on the laptop right away. First:

  1. Connect the charger and check if the power light is on.
  2. Start your laptop without lid (if possible) and make sure the cooler is spinning.
  3. Check the operation of the keyboard, touchpad and ports (USB, HDMI).
⚠️ Attention: If after assembly the laptop DNS does not turn on, but the power indicator is on, the problem may be incorrectly connected screen cable or RAM. Double check all connectors!
💡

The most common mistake during assembly is forgetting to connect the touchpad cable. This results in the cursor not moving even though the keyboard works.

Typical problems after disassembly and their solutions

Even with careful disassembly, problems may occur. Let's look at the most common ones:

Problem Possible reason Solution
Laptop won't turn on The power cable or RAM is not connected Disassemble and check connectors
Screen doesn't work The matrix cable or connector is damaged Reconnect the cable, replace if necessary
The cooler is constantly running at maximum Fan connector not connected Check the connector FAN on the motherboard
Touchpad does not respond The cable is disconnected or the controller is damaged Reconnect the cable, update the driver

If after cleaning the laptop DNS became warm up morethan before disassembly, probable reasons:

  • Too thick layer of thermal paste (optimally - 0.1–0.3 mm).
  • The radiator is poorly secured (the screws are not tightened).
  • The thermal pad on the memory chips or VRM is damaged.

In models with discrete graphics (For example, DNS 15.6" GTX 1650) Pay special attention to cleaning the second radiator. Its dust often blocks the air ducts, which leads to GPU throttling.

FAQ: Frequently asked questions about disassembling DNS laptops

Is it possible to disassemble a DNS laptop without removing the keyboard?

Most models no. The keyboard blocks access to the motherboard and cables. The exception is some DNS Ultrabook, where the RAM and SSD are located under the bottom cover. But to clean the cooler or replace thermal paste, you must remove the keyboard.

Which screw should I unscrew first?

Start with screws in the corners bottom cover - they are usually shorter and less susceptible to “sticking”. In models with a metal body (for example, DNS Gaming) First loosen all screws 1-2 turns, then unscrew completely.

What to do if the housing latch is broken?

If the plastic latch is cracked but not completely broken off, it can be strengthened epoxy glue (For example, Moment Super Epoxy). If the latch is missing, replace the bottom cover (look for the article number by laptop model + “bottom case”).

How often should you clean your DNS laptop from dust?

Recommended Frequency:

  • Office models (For example, DNS 14.1" Celeron): once every 12–18 months.
  • Gaming laptops (DNS RTX 3060): once every 6–8 months.
  • Laptops in dusty rooms: once every 3–4 months.

Signs that cleaning is necessary: increased cooler noise, spontaneous shutdowns, hot case in the area F1–F12.

Can a vacuum cleaner be used for cleaning?

It is possible, but with reservations:

  • Use minimum power (or a special attachment for electronics).
  • Keep the vacuum cleaner at a distance 3–5 cm from the fee.
  • Do not touch the nozzle to the components - Static electricity can damage them.
  • Better to combine with soft brush for hard to reach places.
