Preparing for Disassembly: Tools and Precautions

Before you begin disassembling, make sure you have everything you need. Samsung NP355V5C does not require exotic tools, but some moments (for example, removing the keyboard) will require care.

Here minimum setwhich you will need:

  • ✅ Plastic spatula (or mediator) - to disconnect the lid latches.
  • ✅ Phillips screwdriver PH0 or PH1 — for cover screws and internal fastenings.
  • ✅ Tweezers - for removing small parts (for example, cables).
  • ✅ Thermal paste (if you are planning a replacement) - for example, Arctic MX-6 or Noctua NT-H2.
  • ✅ Antistatic wrist strap (optional) - to protect components from static electricity.
  • ✅ Container for screws - so as not to lose fasteners (in NP355V5C screws of different lengths!).
⚠️ Attention: Do not use metal screwdrivers to release plastic latches - this will cause chips! A plastic spatula or a special tool for disassembling smartphones is ideal.

Also necessarily:

  • 🔌 Disconnect your laptop from the network and remove the battery (we will look at its fastening below).
  • 📸 Take a photo of the location of the cables and screws before disconnecting - this will simplify reassembly.
  • 🧹 Work on a clean, flat surface without carpets (they accumulate static electricity).
📊 Have you disassembled laptops before?
  • Yes, many times
  • 1-2 times
  • No, this is my first experience
  • I plan to take it apart for the first time

Removing the Bottom Cover: Hidden Latches and Screws

Bottom cover Samsung NP355V5C attached to 8 screws (6 short and 2 long under rubber feet) and plastic latches. The main difficulty is to carefully remove the latches without breaking them.

Procedure:

  1. Turn the laptop over and remove the rubber feet (two long screws are hidden under them). Gently pry them off with your fingernail or a plastic spatula.
  2. Unscrew all 8 screws (don't lose them - they are different lengths!). The screws under the legs are usually longer than the others.
  3. Begin to remove the cover from corner next to the battery — here the latches are less fragile. Insert a plastic spatula into the gap and gently move along the edge.
  4. Once the lid begins to come off, don't pull it too hard — there may be latches around the perimeter inside. Use a spatula to go over all sides.

If the lid does not budge, do not use force - in 90% of cases the problem is an unscrewed screw or an unnoticed latch under the battery. Check all fastenings again.

Removing the Battery and Accessing the Hard Drive

After removing the bottom cover you will see the battery, hard drive (HDD), RAM and cooling system. Let's start with the battery - it needs to be disconnected before further manipulations.

How to remove the battery:

  1. Disconnect battery cable from the motherboard (it is usually black and marked as BATTERY). Gently pull the plastic connector without pulling the wires!
  2. Unscrew one screw, fixing the battery (located in the center under the cover).
  3. Lift the battery by the edge and remove it. Be careful - in some revisions NP355V5C The battery is glued with double-sided tape.

Now let's move on to hard drive. In this model it is located in a separate compartment and is secured with 4 screws:

  • ⚙️ Unscrew the 4 screws in the corners HDD-compartment
  • 🖥️ Gently pull the hard drive away from the connector SATA (don't force it - it should come out easily).
  • 🔄 If you are planning to replace it with SSD, make sure the new drive is thick 7 or 9.5 mm (in NP355V5C both options are supported).
⚠️ Attention: When extracting HDD do not touch the contacts with your fingers SATA - This may damage the connector on the motherboard.
How to transfer data from old HDD to new SSD?

If you install SSD instead of HDD, copy the data using:

1. USB-SATA adapter (connect the old drive as an external one).

2. Programs for cloning (Macrium Reflect, Clonezilla).

3. Or reinstall Windows from scratch (recommended for system cleanliness).

Replacing RAM and cleaning the cooler

B Samsung NP355V5C installed two RAM slots (supported up to 16 GB DDR3L). Replacing memory is one of the simplest operations, but there are nuances here too.

How to change RAM:

  1. Squeeze clamps along the edges of the memory module (they will automatically move apart).
  2. Carefully remove the old module by pulling it upward at an angle of ~30°. Do not touch the contacts!
  3. Install the new module by aligning cutout on the placket with a protrusion in the slot. Press until the latches click.

If you notice that the laptop overheats or makes noise, it's time to clean the cooling system. B NP355V5C The cooler and radiator are secured with 4 screws:

  • 🔧 Unscrew the cooler mounting screws (they may be hidden under thermal pads).
  • 🧹 Remove dust from fan blades soft brush or a can of compressed air.
  • 🧪 If you are replacing thermal paste, completely remove the old one (you can use alcohol and a lint-free cloth).
💡

If after cleaning the cooler is still noisy, check bearing. B NP355V5C The fan often breaks down Delta - it can be replaced with an analogue (for example, Sunon with the same connector).

Removing the keyboard and accessing the motherboard

For deep disassembly (for example, replacing Wi-Fi-module or chipset) you will need to remove the keyboard. B NP355V5C it is attached to 5 latches on top and one train.

Step by step instructions:

  1. Gently pry up the keyboard with a plastic spatula from above (above the key Esc). The latches are located along the top edge.
  2. Lift the keyboard and disconnect the cable (it's under the metal latch - lift it up).
  3. Place the keyboard on the touchpad (do not disconnect the cable completely to avoid damaging the connector).

Below the keyboard you will see:

  • 📶 Wi-Fi module (standard M.2 2230, supports 802.11n).
  • 🔌 Power connector (a common problem is contact oxidation).
  • 🖥️ Chipset and Northbridge (if overheating, the thermal paste needs to be replaced).
⚠️ Attention: Keyboard cable in NP355V5C very fragile! If it breaks, you will have to look for a donor or buy a new keyboard (article: GH76-03175A).

Typical problems and how to avoid them

Disassembly Samsung NP355V5C usually resolves without complications, but there are a few common mistakesthat lead to breakdowns:

Problem Reason How to avoid
Broken lid latches Excessive force when opening Use a plastic spatula and check all screws
Torn keyboard cable Abrupt detachment without fixing the latch Lift the latch before removing the cable
Connector damage SATA Sloppy extraction HDD Pull the disk strictly perpendicular to the board
Overheating after assembly Incorrect application of thermal paste Use a thin layer (0.1–0.2 mm) and spread evenly

Another common problem is touchpad not working after assembly. This happens if you forget to connect its cable (it is located under the keyboard, next to Wi-Fi-module).

1. Connecting the battery and power supply.

2. Correct installation of RAM.

3. State of the keyboard cable (it can block switching on).-->

Reassembly: Inspection and Testing

Assembly NP355V5C goes in reverse order, but there are a few critical moments:

  • 🔩 Make sure that all screws are tightened - a missing screw can lead to vibrations and damage to the board.
