We disassemble a Samsung laptop ourselves: from preparation to assembly

Disassembling a laptop Samsung - 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 and tools, the process is easier than it seems. This article will help you understand the nuances of disassembling various series - from budget NP300 up to bonus Galaxy Book Pro, — and also avoid typical mistakes that lead to breakdowns.

We won't try to convince you that disassembly is easy. Every laptop Samsung There are some pitfalls: hidden latches, non-obvious battery mounts, or thermal paste that can flood the motherboard if not handled carefully. But if you are willing to spend 1-2 hours on careful preparation, the result will live up to your expectations. Perhaps you need clean the cooling system, replace thermal paste or increase the amount of RAM - in any case, our guide will become a reliable assistant.

Preparing for Disassembly: Tools and Safety Precautions

Before you start disassembling, make sure you have everything you need. The lack of even one tool can turn the process into agony. For example, without plastic pick you risk damaging the case latches, and without antistatic wrist strap — burn sensitive microcircuits with a static discharge.

Here is the minimum set you will need:

• 🔧 Screwdriver set (Crusades) PH00, PH0, straight 1.5 mm, 2 mm, and also Torx T5 for some models)
• 📏 Plastic picks (or guitar picks) to separate the body
• 🧲 Magnetic mat or a container for screws (so as not to lose small parts)
• ⚡ Antistatic wrist strap (or at least periodically touch the metal case of the system unit)
• 📸 Smartphone for photographing each stage (useful for reassembly)

Pay special attention place of work. The ideal option is a large table with good lighting and without carpets (they accumulate static electricity). If you are dismantling your laptop on the floor, use antistatic mat or at least an ordinary wooden board.

⚠️ Attention: Laptops Samsung series Galaxy Book Flex And Galaxy Book Ion have an aluminum body with adhesive joints. To disassemble them you will additionally need hair dryer (to soften the glue) and suckers (same as for smartphones). Without this, the risk of damaging the case is 80%.

We determine the model and look for a disassembly diagram

Not all laptops Samsung are understood in the same way. For example, Samsung NP300E5E has a classic design with access to the hard drive and RAM through a separate cover, and Galaxy Book Pro 2 requires complete disassembly even to replace the SSD. Therefore the first step is exact model identification.

You can find it:

• 🏷️ On sticker on the bottom (look for inscriptions like Model: NP750XED-KA1RU)
• 🖥️ B BIOS (when loading, click F2 or Del)
• 🔍 Via Device Manager in Windows (section "System devices")

Once the model is determined, find official service manual (Service Manual). For most laptops Samsung You can download them from sites like ManualsLib or LaptopMain. If the manual is missing, study the disassembly on YouTube - look for videos with your exact model (for example, “Samsung Galaxy Book Flex2 disassembly»).

Laptop series	Disassembly Features	Difficulty (1-5)
Galaxy Book Pro/Pro2	Adhesive housing, battery with screws under the cover	5
NP300/NP350	Separate cover for HDD/RAM, simple design	2
Notebook 9 (2018)	Hidden latches under rubber feet	4
Odyssey	Metal housing with torx screws	3

Step-by-step disassembly: from cover to motherboard

Let's start with the simplest option - disassembling a laptop with a separate cover for RAM and storage (for example, Samsung NP300E5E). If you have a unibody model (like Galaxy Book Pro), skip the first steps and proceed to the section on separating the chassis.

Step 1: Turn off the power and remove the battery

• ⚡ Turn off the laptop and disconnect the charger.
• 🔋 Turn the device over and slide the battery latch to the Unlock (if there is one). In models without a removable battery (for example, Galaxy Book Flex) First you need to remove the bottom cover.
• 📷 Take a photo of the location of the screws - this will save time during assembly.

Step 2: Removing the Bottom Cover

• 🔧 Remove all screws (usually they are marked with arrows or a K for keyboard). In some models, the screws are hidden under rubber feet - carefully pry them off.
• 🕳️ Insert a plastic pick into the gap between the lid and the body and carefully move along the perimeter. If the cover does not budge, check that all screws are removed.

Step 3: Accessing Internal Components

After removing the cover you will see:

• 💾 Hard drive/SSD (usually secured with 1-2 screws)
• 🧠 RAM (in slots DIMM, fixed with latches)
• 🌡️ Cooling system (heatsink and fan screwed to the motherboard)
• 🔌 Battery (can be glued or fixed with screws)

⚠️ Attention: In laptops Samsung with discrete graphics (for example, NP700G7C with NVIDIA GeForce) the heatsink is often connected to the GPU and CPU by a common heat pipe. Do not try to remove it without preheating - the thermal paste may “stick” and damage the chips.

How to remove a glued battery?

For models with a bonded battery (e.g. Galaxy Book Ion):

1. Gently pull the special loop (if there is one).

2. If there is no loop, pry off the battery with a plastic spatula, after heating the glue with a hairdryer (temperature no higher than 60°C).

3. Do not use metal tools - risk of short circuit!

Cleaning the cooling system and replacing thermal paste

One of the main reasons for disassembling a laptop is overheating. If your Samsung turns off under load or constantly runs at high fan speeds, the problem is most likely dust or dried thermal paste. Let's look at the cleaning and replacement process using an example Samsung Notebook 9 (2018).

Step 1. Dismantling the cooling system

• 🔧 Unscrew the screws securing the radiator (usually 4-6 pieces). Be careful - some screws may be different lengths!
• 🧹 Carefully remove the radiator. If it doesn't give in, don't use force - in 30% of cases the thermal paste “sticks” to the processor, and a sudden movement can tear the chip off the board.
• 🧽 Clean the radiator and fan from dust using soft brush And compressed air can.

Step 2: Removing Old Thermal Paste

• 🧻 Use lint-free wipes And isopropyl alcohol (90%+).
• ❌ Do not use acetone or solvents - they can damage plastic elements.
• 🎯 Pay special attention to any remaining thermal paste on VRM modules (small chips around the processor).

Step 3: Apply new thermal paste

• 🅿️ For processors Intel (For example, i5-8250U in NP850XBB) enough peas 4-5 mm.
• 🔥 For AMD Ryzen (as in Galaxy Book Flex2 15) apply criss-cross — these processors heat up more.
• 🛠️ Recommended thermal pastes: Arctic MX-6, Noctua NT-H2, Thermal Grizzly Kryonaut.

Replacing RAM and storage

Update RAM or SSD - the most common reason for disassembling laptops Samsung. In most models this can be done without complete dismantling, but there are exceptions (for example, Galaxy Book Pro, where the SSD is soldered to the board).

Replacing RAM

• 🧠 On laptops Samsung usually used DDR4 SO-DIMM (for example, in NP750XED - two slots).
• 🔄 To remove the bar, carefully spread the latches on the sides and pull it up at an angle of 30°.
• ⚠️ Make sure the new memory is compatible with the motherboard. For example, Samsung Notebook 9 (2018) supports maximum 16 GB DDR4-2400.

Replacing SSD

• 💾 Most models use the format M.2 2280 (For example, Samsung 970 EVO Plus).
• 🔧 The SSD is fixed with one screw. After unscrewing it, the drive can be easily removed at an angle.
• 🔄 When installing a new SSD, make sure it is NVMe, not SATA - in modern laptops Samsung connector M.2 usually only supports PCIe.

⚠️ Attention: In laptops Samsung Galaxy Book Flex Alpha And Galaxy Book S storage device soldered to the board. Replacement is only possible at a service center using a soldering station.

Common mistakes and how to avoid them

Even experienced users sometimes make mistakes when disassembling. Here are the most common ones and how to prevent them:

Error	Consequences	How to avoid
Using the wrong screwdriver	The screw splines are torn off, the housing is damaged	Use magnetic bits and screwdrivers with precision tip
Application of force when removing the radiator	Separation of the processor from the board, damage to the chips	Preheat the radiator with a hairdryer (50-60°C) and gently rock it
Incorrect installation of screws	Short circuit, board damage	Store screws in labeled containers or take photographs of their locations
Ignoring antistatic agents	Failure of RAM, SSD or South Bridge	Use antistatic wrist strap or periodically touch a grounded object

Another common problem is cable damage. In laptops Samsung Keyboard and touchpad cables often pass under the battery or motherboard. If handled carelessly, they are easy to tear. Always disconnect cables for a plastic connector, and not by the wires!

1. Connecting the battery and power supply.

2. Correct installation of RAM (the strips should click).

3. No foreign screws or metal objects on the board.

In 60% of cases, the problem is solved by re-disassembling and checking the contacts.-->

Assembling a laptop and checking its functionality

Assembly is no less important process than disassembly. Main rule: work in reverse order, making sure that all cables and connectors are connected correctly. Start by installing the motherboard (if you removed it), then connect the cables and install the cooling system.

Assembly order:

1. Install processor (if removed) and apply thermal paste.
2. Secure radiator and connect the cooler.
3. Connect the cables keyboards, touchpad And display.
4. Install battery and secure it with screws/glue.
5. Close bottom cover, starting with the latches at the screen hinges.
6. Tighten all screws (do not overtighten!).

After assembly:

• 🔌 Connect the charger and try to turn on the laptop.
• 🔊 Check the sound, keyboard, touchpad and ports (USB, HDMI).
• 🌡️ Run a stress test (for example, FurMark for video card) and check the temperatures.

⚠️ Attention: If after assembly the laptop turns on, but the screen does not work, check the connection of the matrix cable. In models Samsung with touch screen (eg Galaxy Book Flex) the cable often consists of two parts: one goes to the matrix, the other to the touchscreen. Make sure both are connected correctly.

FAQ: Frequently asked questions about disassembling Samsung laptops

Is it possible to disassemble a Samsung laptop without voiding the warranty?

In most cases Do-it-yourself disassembly will void the warranty.if there are seals on the laptop (for example, on the screws or cover). However, in some countries (including Russia) there is a law “On Protection of Consumer Rights”, which allows you to open the device for replacement of removable components (RAM, SSD) without loss of warranty. Check conditions with your service center.

How can you tell if the thermal paste has dried out and is time to change it?

Signs of dried out thermal paste:

• Laptop overheats even under low load (CPU temperature above 90°C).
• Fan runs at maximum speed constantly.
• Performance falls due to throttling (checked in HWMonitor).
• The thermal paste on the radiator has become hard and cracked.

On average, it is recommended to change the thermal paste once every 2-3 years.

What to do if after disassembling the laptop does not turn on?

Diagnostic algorithm:

1. Check your connection battery and power supply.
2. Make sure RAM installed correctly (try rearranging the slats).
3. Check power button - sometimes the cable moves away from the board.
4. If the laptop responds to the power button (indicators are on, but the screen is black), the problem may be video card or matrix cable.
5. If there is no reaction, perhaps short circuit on the board (check for any foreign screws).

In 80% of cases, the problem is solved by re-disassembling and checking the contacts.

Is it possible to replace the keyboard on a Samsung laptop yourself?

Yes, but the complexity depends on the model:

• B NP300/NP350 The keyboard is attached with latches and one cable - replacement will take 15-20 minutes.
• B Galaxy Book Pro The keyboard is glued to the case, and replacement will require hair dryer And suckers.
• B Notebook 9 The keyboard is integrated with the touchpad - you will have to disconnect both cables.

The main thing is not to damage the cable! We recommend that you first watch the video disassembly for your model.
