Disassembling an HP Pavilion laptop: a step-by-step guide with photos and expert advice

Disassemble the laptop HP Pavilion doing it yourself is a task that scares many users. The fear of breaking latches, damaging cables, or losing screws often stops even experienced equipment owners. However, with the right approach and knowledge of the nuances of the design, the disassembly process becomes predictable and safe. In this article we will look in detail at how to remove the back cover, remove the battery, get to the cooling system and replace key components - from RAM to solid state drive.

Feature of the line Pavilion (including popular models 15-dw1xxx, 14-dv2xxx, x360) is a modular architecture that simplifies upgrades, but is fraught with hidden pitfalls. For example, some screws may be hidden under the legs, and plastic latches may break if opened incorrectly. We'll show you how to avoid these mistakes, which tools are really needed (spoiler: it’s not always a Phillips screwdriver!), and we’ll give you a checklist for preparing the workplace.

Important: if your HP Pavilion Still under warranty, disassembly will void it. In this case, it is better to contact a service center. For everyone else, head on to the step-by-step guide!

Preparing for disassembly: tools and work area

Before you grab a screwdriver, make sure you have everything you need. Unsuitable tools are the leading cause of damage to the housing and internal components. Here is the minimum set that will be needed for most models Pavilion:

• 🔧 Screwdriver set with bits PH0 (cross, size 0) and T5 (asterisk). The latter are often used to mount SSDs.
• 📏 Plastic picks (or guitar picks) - for carefully prying the latches. Metal tools scratch the body!
• 🧲 Magnetic mat or a container for screws (so as not to lose small parts).
• 🔋 Antistatic wrist strap (optional, but recommended to protect electronics from static discharge).
• 📷 Smartphone - to photograph the cable location before disconnecting.

The work area should be level, well lit and without carpets (they accumulate static electricity). Place the laptop on a soft cloth to avoid scratching the lid. If you are disassembling a model with a touch screen (for example, Pavilion x360), make sure the screen is closed - this will reduce the risk of damage to the display cable.

⚠️ Attention: Some models HP Pavilion (For example, 15-eh series) have hidden screws under the rubber feet. If you do not unscrew them in advance, you may break the plastic fasteners when trying to remove the cover.

Removing the back cover: secrets of latches and screws

The first and most critical stage is dismantling the bottom panel. This is where the majority of newbie mistakes lie. Let's start with the screws:

1. Turn the laptop over and disconnect the battery (if it is removable). If the battery is soldered, disconnect the power cable from the motherboard after removing the cover.
2. Unscrew all visible screws (usually there are 8–12 of them). In models Pavilion 15-dw1xxx Often there are screws of different lengths - remember where they were!
3. Check rubber feet — additional screws may be hidden under them (especially in models 2021–2023).

Now - the latches. They are located around the perimeter of the lid and require care. Start at the corners where the plastic is thinner:

• 🔹 Insert the plastic pick into the gap between the cover and the body (battery side).
• 🔹 Smoothly move the pick along the seam, one by one releasing the latches. Don't force it - if the cover doesn't budge, you've missed a screw!
• 🔹 For models Pavilion x360 latches can be two-level - first release the top row, then the bottom.

Model HP Pavilion	Number of screws	Latch type	Hidden fastenings
15-dw1000–15-dw2000	10–12	Plastic, single-level	Screws under the legs
14-dv2000–14-dv3000	8–10	Metal + plastic	Battery latches
x360 (all series)	6–8	Two-level	Screws under the decorative panel
17-by	14+	Reinforced metal	Mounts under the keyboard

⚠️ Attention: In models Pavilion 15-eh and newer, the back cover can be glued around the perimeter. In this case, you will need a hairdryer to soften the glue (temperature ~60°C). Do not use a knife - it will damage the body!

Removing the battery and disconnecting the cables

After removing the cover, you will see the battery (if it is removable) and several cables. The main rule here is do not pull the wires, and carefully disconnect the connectors. Let's start with the battery:

Most models Pavilion The battery is secured with 4–6 screws. Unscrew them, then pry the battery out with a plastic spatula. If the battery is stuck, do not use force - warm it up with a hairdryer (maximum 50°C) and try again. In models x360 The battery is often glued, and you will have to carefully “peel it off” using a thread (pass it under the battery and saw it back and forth).

Now - the trains. There are usually three of them:

• 🔌 Touchpad cable — located in the center, secured with a latch. To disconnect, pull the black “tab” up.
• 🔌 Keyboard cable - is located closer to the top. Be careful: its connector is fragile!
• 🔌 Display cable - the widest, often glued with tape. Don't pull the wires - grab the connector.

On Pavilion 2022+ models, the keyboard cable can be soldered to the motherboard. There is no use in trying to disconnect it - just replace the entire board.

Access to the cooling system: cleaning and replacing thermal paste

Overheating is a common problem HP Pavilion, especially in game modifications with a video card NVIDIA MX. To get to the cooler and radiator, you need:

1. Unscrew the cooling system mounting screws (usually 4–6 pieces with springs). The screws can be of different lengths - remember their location!
2. Carefully remove the radiator. If it is “stuck” to the processor, do not pull it - warm it up with a hairdryer (60–70°C) and rotate the radiator left and right.
3. Clean the fan from dust with a brush or a can of compressed air. Do not use a vacuum cleaner - it creates static electricity!

Replacing thermal paste is a critical step. B Pavilion Cheap thermal paste is often used, which dries out in 1–2 years. Apply new paste (eg Arctic MX-4) thin layer (0.1–0.2 mm). Excess paste leads to overheating!

Processor model	Recommended thermal paste	Temperature under load (normal)
Intel Core i3/i5 10th–11th generation	Arctic MX-4, Noctua NT-H1	70–85°C
AMD Ryzen 5/7 4000/5000	Thermal Grizzly Kryonaut	75–90°C
Intel Core i7 12–13 generation	Coollaboratory Liquid Ultra	80–95°C

⚠️ Attention: In models with a video card NVIDIA MX450/MX550 The heatsink is often attached to the GPU and CPU at the same time. When removing the heatsink, do not tilt it - you can damage the memory chips on the video card.

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

Check if the power cable is connected to the motherboard (common error). If the laptop turns on, but there is no image, reconnect the display cable. If the cooler does not rotate, make sure that its connector is connected to the motherboard (usually 2-pin or 3-pin).

Replacing RAM and storage drives

One of the main reasons for disassembly HP Pavilion - upgrade RAM or SSD. In most models, access to the memory slots and M.2 connector opens immediately after removing the cover. However, there are nuances:

RAM:

• 🖥️ In models 15-dw And 14-dv usually 2 slots DDR4 SODIMM. The maximum supported volume is 32 GB (2x16 GB).
• 🖥️ Memory operates in dual-channel mode only if the modules are of the same frequency. For example, 8 GB 3200 MHz + 16 GB 2666 MHz will give single-channel mode.
• 🖥️ In models with soldered memory (for example, some Pavilion x360) upgrade is not possible.

Drives:

• 💾 M.2 SSD (connector Key M) - supports NVMe And SATA. In models 2020+ usually only NVMe.
• 💾 2.5" SATA - found in older models (until 2019). To replace it, you will need to remove the optical drive (if any).
• 💾 In some Pavilion 17-by there are two M.2 connectors, but the second one may be occupied Wi-Fi module.

When replacing an SSD, be sure to transfer your Windows license if it was associated with the old drive. To do this, use the utility ProduKey from NirSoft.

Assembling a laptop: how to avoid mistakes

Assembly is no less important process than disassembly. The main thing here is sequence And neatness. Start by reconnecting the cables:

1. Connect the display cable, then the keyboard and touchpad. Make sure that the connector latches are locked (you should hear a click).
2. Install the battery and tighten the screws. For models with a glued battery, use new double-sided tape.
3. Secure the cooling system. Tighten the screws criss-crossto avoid skewing the radiator.

When installing the back cover:

• 🔧 Start by fixing the latches in the corners, then gradually snap the lid around the perimeter.
• 🔧 Tighten the screws in the reverse order (first long, then short). Do not overtighten - this will deform the body!
• 🔧 Check that all rubber feet are in place. They not only prevent slipping, but also cover the screws.

After assembly, turn on the laptop and check:

• 🔋 Is charging working (the indicator should be on).
• 🖱️ Is the touchpad and keyboard responsive?
• 🔊 Is there sound (sometimes the speaker cable comes out).
• 🌡️CPU temperature in HWMonitor (should be 40-50°C when idle).

⚠️ Attention: If after assembly the laptop does not turn on, but the power indicator is on, the problem may be an unconnected keyboard or touchpad cable. In 80% of cases, this is solved by re-disassembling and checking the connectors.

Common mistakes and how to avoid them

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

Error	Consequences	How to avoid
Using a metal screwdriver for latches	Scratches on the body, broken fasteners	Use plastic picks
Tightening the Screws	Cracks on the motherboard, broken threads	Tighten the screws with a force of 0.5–0.8 Nm
Disconnecting cables by wires	Damage to contacts, broken wires	Grasp the connector only, pull perpendicular to the board
Ignoring hidden screws	Broken latches, deformed cover	Check legs, labels, decorative panels
Incorrect replacement of thermal paste	Overheating, shutdowns under load	Apply a thin layer, use swing paste

Another typical problem is loss of screws. To avoid this, use a magnetic mat or container with cells. If the screw is lost, do not replace it with the first one you come across - HP Pavilion Screws of different lengths (eg 3mm and 5mm) are often used. Buy an original kit for your model (part numbers can be found in the documentation).

FAQ: answers to frequently asked questions

Is it possible to disassemble the HP Pavilion without special tools?

Theoretically, yes, but the risk of damage increases significantly. For example, many people use a knife instead of a plastic pick, which leads to scratches or broken latches. Minimum set - screwdriver PH0 and a plastic card (for example, a bank card). For models with a glued battery, a hairdryer will be required.

How can you tell if your laptop is properly disassembled if it doesn’t turn on?

First check:

1. Is the power cable connected to the motherboard (it often comes off when cleaning).
2. Are all the screws of the cooling system tightened (a radiator that is not tightened can block startup).
3. Is the battery connected (even if the laptop is running on mains power).

If the power indicator is on, but the screen is black, the problem is in the display cable or RAM (try reinstalling the RAM modules).

Which thermal paste is best to use for HP Pavilion with AMD Ryzen?

For processors AMD Ryzen 5/7 4000/5000 (For example, Ryzen 7 5700U) pastes with high thermal conductivity are recommended:

• Thermal Grizzly Kryonaut (12.5 W/mK) - the best option for gaming laptops.
• Coollaboratory Liquid Ultra (liquid metal, 38 W/mK) - for extreme cooling, but requires careful application.
• Noctua NT-H2 (8.9 W/mK) - a universal choice for office tasks.

Avoid cheap toothpastes (eg. KPT-8) - they dry out in 6–12 months.

Can I replace the keyboard on my HP Pavilion myself?

Yes, but this is one of the most difficult operations. The keyboard is secured with latches and screws under the touchpad. Basic steps:

1. Remove the back cover and disconnect the keyboard cable.
2. Using a plastic spatula, carefully pry up the keyboard, starting at the top (where the buttons are). F1–F12).
3. Unscrew the mounting screws (usually 2-4 pieces under the keyboard).
4. Install the new keyboard in reverse order.

Difficulty: high risk of damaging the cable. If the keyboard does not work after replacement, check whether the cable under the touchpad is kinked.

How often should I clean the cooling system in my HP Pavilion?

The recommended cleaning frequency depends on the operating conditions:

• 🏠 Home use (little dust) - once every 1.5–2 years.
• 🏢 Office (average dust content) - once a year.
• 🎮 Game mode (constant loads) - every 6–8 months.
• 🚬 Smokers/pets — every 3–4 months (dust + resins quickly clog the radiator).

Signs that it’s time to clean: constant cooler noise, temperature above 90°C under load, spontaneous shutdowns.
