Disassembling an HP Pavilion laptop: step-by-step guide with photos and tips

Laptops HP Pavilion are one of the most popular devices for work and entertainment, but sooner or later the user is faced with the question: how to independently disassemble the laptop for cleaning, replacing thermal paste or upgrading components? Unlike monolithic ultrabooks, the series Pavilion (especially models 15- And 17-dw) often allows disassembly without specialized tools. However, even here there are pitfalls: hidden latches, fragile cables and the risk of damaging plastic clips.

This article will help you avoid mistakes during disassembly. We will analyze the process in detail - from preparing the workplace to removing the motherboard - taking into account the characteristics of different generations Pavilion (2018–2026). We will pay special attention models with discrete graphics (For example, HP Pavilion Gaming 15) where cooling requires more frequent maintenance. If you are planning to replace SSD M.2, add RAM or simply clean the cooling system, here you will find current diagrams and unique techniques for safely removing the cover without damaging the housing.

Preparing for Disassembly: Tools and Safety Precautions

Before you begin, make sure you have everything you need. For disassembly HP Pavilion you will need:

• ✅ Plastic spatula (or mediator) - for releasing the lid latches without scratches.
• ✅ Phillips screwdriver PH00 (for most screws) and TORX T5 (for some 2022+ models).
• ✅ Antistatic wrist strap or at least a grounded surface - static electricity can damage the motherboard.
• ✅ Thermal paste (For example, Arctic MX-6 or Noctua NT-H2) - if you plan to replace it.
• ✅ Containers for screws — magnetic trays or packages with markings (for example, “Lid”, “Cooler”).

Important: before disassembling completely discharge the battery (to 0%) and disconnect the charger. In models HP Pavilion x360 (Transformers) the battery is often soldered to the board, so disconnecting it requires special care. If you are working with a laptop under warranty, remember: do-it-yourself disassembly voids warranty obligations (except when the documentation states otherwise, as is the case with some models with user-upgradable RAM).

⚠️ Attention: On laptops HP Pavilion 15-ec (2020–2021) there is a touchpad cable running under the keyboard, which can be easily damaged if the top panel is removed carelessly. If you are not confident in your skills, start by removing the bottom cover.

Removing the bottom cover: hidden latches and typical mistakes

Let's start with the most difficult stage - dismantling the bottom panel. B HP Pavilion it is secured not only with screws, but also with plastic latches that are easy to break. Here is a step-by-step algorithm:

1. Turn the laptop over and remove all visible screws (usually 8-12). In models 15-dw1xxx one screw may be hidden under the rubber foot - check it!
2. Carefully pry off the lid plastic spatula, starting from the corner next to HDD/SSD-compartment Do not use force - if the cover does not budge, you have missed a screw.
3. Disconnect the cables (if they exist). B Pavilion Gaming Under the cover there may be an additional connector for the keyboard backlight.

A typical mistake for beginners is trying to remove the cover with a jerk. As a result, the clips break and the later cover begins to hang loose. To avoid this, move the spatula along the seam, releasing the latches one by one. In models 17-by (with a number block) the lid is more difficult to attach - here you may need a second spatula to simultaneously press on opposite sides.

Access to components: RAM, SSD and HDD

After removing the cover you will see the main components. Most models HP Pavilion available for upgrade:

• 🖥️ RAM: usually 2 slots DDR4 SODIMM (maximum 32–64 GB depending on model). B Pavilion 15-dw one slot is often occupied by soldered memory.
• 💾 Drives:
  • M.2 SSD (usually PCIe NVMe, less often SATA).
  • 2.5" HDD/SDD (in models with two drives).
• 🔋 Battery: in most cases removable (except x360 and some ultrabooks).

For replacement RAM Simply unclip the latches on the sides of the module and remove it. When installing new RAM, make sure it is compatible with your model - e.g. Pavilion 15-ec supports DDR4-3200, and the older ones 15-dw - only DDR4-2400. For M.2 SSD You will need to unscrew one screw and carefully remove the drive at an angle of 30°.

⚠️ Attention: On laptops HP Pavilion with hybrid graphics (NVIDIA MX or GTX) when replacing thermal paste, you must also clean the contacts of the discrete GPU from the old paste - otherwise overheating is possible.

Cleaning the cooling system and replacing thermal paste

Overheating is a common problem HP Pavilion, especially in gaming models. To clean the cooler and radiator:

1. Disconnect the battery (if removable) and disconnect the cooler cables.
2. Unscrew the screws securing the cooling system (usually 4–6 pieces). Be careful - in Pavilion Gaming The heatsink can be glued to the GPU.
3. Remove the cooler and clean it soft brush or compressed air. Do not use a vacuum cleaner - it creates static electricity!
4. Remove old thermal paste from the CPU and GPU with alcohol (90%+). Apply a thin layer of the new paste (about the size of a pea).

In models with NVIDIA GTX 1650 or RTX 3050 The problem of thermal pads “drying out” on GPU memory chips is often encountered. If after cleaning the temperature has not decreased, check their condition and, if necessary, replace them with new ones (1–1.5 mm thick).

Removing the keyboard and top panel (for experienced ones)

If you need to get to the touchpad, webcam, or display cables, you'll need to remove the keyboard. This process is more complex and risky:

1. Remove the screws under the bottom cover (usually 2-3 at the top of the laptop).
2. Carefully pry the keyboard off with a plastic spatula, starting at Space. B Pavilion x360 it is fastened with latches, in other models - with screws.
3. Disconnect the keyboard cable (it's fragile!). Gaming models may have an additional backlight cable.

Under the keyboard you will find:

• 🔊 Speakers (in Pavilion 15 they are often glued with double-sided tape).
• 📷 Webcam and its cable (in Pavilion 14 The camera is integrated into the display).
• 🖱️ Touchpad (in Pavilion Gaming it can be secured with screws).

⚠️ Attention: On laptops HP Pavilion with touch screen (x360, 15t-touch) the display cable runs under the keyboard. Damage to it will result in a non-functional touchscreen or streaks on the screen.

Assembling a laptop: checking and testing

Once completed, reassemble the laptop in reverse order, following these tips:

• ✅ Check that all cables are connected all the way - even a small play can cause errors.
• ✅ Tighten the screws criss-crossto avoid distortion of the cover.
• ✅ After assembly, turn on the laptop and check:
  • Keyboard operation (especially Fn-keys).
  • Temperature in HWMonitor (should be below 50°C when idle).
  • Display in BIOS new RAM or SSD.

If the laptop does not turn on after assembly, check:

1. Battery connection (in Pavilion 15-ec The connector may not be fully secured).
2. Motherboard power cable (in models with discrete graphics it sometimes comes off).
3. Presence of post codes (flashing indicators Caps Lock/Num Lock indicates a RAM or GPU error).
