How to carefully remove the back cover of an HP Pavilion laptop: instructions with photos and tips

Disassembling a laptop HP Pavilion - a task that sooner or later faces every owner who wants to replace thermal paste, add RAM or install an SSD. However, removing the back cover incorrectly can damage the latches, cables, or even the motherboard. In this article we will figure out how to remove the cover without risk, what tools are needed and what to look for depending on the model of your Pavilion.

It is important to consider that the design of laptops HP Pavilion varies depending on the year of manufacture and series (for example, Pavilion 15, Pavilion x360 or Pavilion Gaming). We'll focus on universal principles, but also point out key differences for popular modifications. If you have never disassembled equipment before, don’t worry: with the right approach, the process will take no more than 20–30 minutes.

Preparation: Tools and Precautions

Before you begin disassembling, make sure you have everything you need. Missing even one tool can complicate the process or lead to damage. Here is the minimum set:

• 🔧 Plastic spatula (or a pick) - for carefully prying off the cover without scratches.
• ⚒️ Phillips screwdriver (usually PH0 or PH1) - for screws.
• 🧲 Magnetic mat or container - so as not to lose small screws.
• 📸 Smartphone - for photographing the location of parts before disassembly.
• 🧴 Alcohol wipes — for cleaning contacts (if necessary).

Pay special attention electrostatic safety. Touching laptop components with static charges can damage them. To avoid this, touch a grounded metal object (such as a radiator) or use an antistatic wrist strap before working. Also Never disassemble a laptop on a carpet or padding surface - they accumulate static electricity.

⚠️ Attention: If your HP Pavilion It is under warranty; disassembling it yourself will void it. In this case, contact the service center HP.

Step 1: Shutdown and Unplug the Laptop

It would seem an obvious point, but many people overlook it. It is not enough to simply turn off the laptop with a button - you need to completely disconnect the system:

1. Close all programs and run complete shutdown via menu Start → Shutdown.
2. Disconnect power supply from the outlet and laptop.
3. If the battery is removable, remove it. In most modern Pavilion (For example, Pavilion 15-ec1xxx) the battery is built-in, so this step is skipped.
4. Press and hold the power button 10–15 secondsto discharge the residual charge of the capacitors.

Why is this important? Even when turned off, voltages may remain on the motherboard, which, if touched carelessly, can damage components. For example, contacts USB-C or HDMI often connected directly to the board and are static sensitive.

Step 2: Removing the Back Cover Screws

Screws on the back cover HP Pavilion may vary in length and diameter. A common mistake for beginners is to put them in one pile and then mix them up when reassembling. To avoid this, follow the algorithm:

1. Turn the laptop over screen down on a soft surface (for example, a towel).
2. Inspect the cover: screws may be hidden under rubber plugs (especially in models Pavilion Gaming). Gently pry them off with a plastic spatula.
3. Unscrew all visible screws, including those located under the legs (if they are removable). Usually there are from 8 to 12 pieces.
4. Lay out the screws on a magnetic mat in the order in which they were unscrewed, or take a photo of their location.

The table below shows typical screw types for different series HP Pavilion:

Laptop model	Screw type	Quantity	Features
Pavilion 15-dw1xxx	PH0 × 5 mm	10–12	One screw under the removable foot
Pavilion x360 14-dh	PH0×3mm And PH0 × 6 mm	8	Long screws hold the screen hinges in place
Pavilion Gaming 15-ec	PH1×5mm (black)	14	4 screws are hidden under rubber plugs
Pavilion 14-ce	PH0 × 4 mm	9	One screw next to the power connector

⚠️ Attention: In models Pavilion x360 Some of the screws can secure not only the cover, but also the screen hinges. If you unscrew them all the way, the screen will become unstable - do not turn the laptop over after this!

Step 3: Carefully separate the cover from the body

The cover still stays in place after removing the screws plastic latches. They need to be snapped off around the perimeter, starting from one of the corners. Here's how to do it right:

• 🔹 Insert the plastic spatula into gap between cover and body at one of the corners (usually it’s easier to start from the bottom right).
• 🔹 Smoothly move the spatula along the edge, applying uniform force. You will hear the characteristic clicks of the clips being released.
• 🔹 Do not try to tear off the cover abruptly - this may break the latches. If the resistance is too strong, check that all screws are removed.
• 🔹 After snapping three sides, lift the lid at an angle 30–45 degrees, since it can be connected via cables (for example, to a touchpad).

In some models (for example, Pavilion 15-cs) the cover is additionally fixed double-sided tape near the battery. If you feel resistance, do not apply force - warm the area with a hairdryer (temperature no higher than 60°C) or carefully pry off the tape with a spatula.

Step 4: Disabling loops (if necessary)

After removing the cover you may see one or more flexible cablesconnecting the cover to the motherboard. Most often this is:

• 🖱️ Train touchpad (usually black, with a latch).
• 🔋 Train battery (red or orange, in models with a removable battery).
• 📶 Antenna wires Wi-Fi module (thin black or white).

To disconnect the cable:

1. Gently lift plastic latch connector (usually white or black).
2. Pull the train perpendicular board, not from side to side.
3. If the cable does not give way, do not pull by force - check whether the additional latch on the back side is holding it.

In models Pavilion Gaming may be present additional keyboard backlight cable. It is thinner than the others and is often glued to the lid - remove it last.

What to do if the cable breaks?

If the touchpad or keyboard cable is torn, it can be replaced (price - from 300 to 1500 rubles, depending on the model). The main thing is not to lose the plastic latch of the connector, since without it the new cable will not be fixed. In extreme cases, the connector can be glued with superglue (be careful not to get it on the contacts!).

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:

• 🔌 Trying to remove the cover without unscrewing all the screws - leads to broken latches. Always check for hidden screws under the feet or rubber plugs.
• 💥 Using a metal screwdriver to pry off the cover - leaves scratches and can slip, damaging the board. Use only plastic or wooden tools.
• 🔋 Disassembly with battery connected - risk of short circuit. Even if the battery is built-in, disconnect its cable first.
• 📱 Lost or misplaced screws — leads to an uneven fit of the lid during assembly. Use a magnetic mat or marker for numbering.

Another common problem is damage to Wi-Fi antenna wires. They are attached to the cover and, if removed abruptly, can come off the connectors on the module. To avoid this, before completely removing the cover, carefully disconnect the antennas from the module (they are usually marked MAIN And AUX).

Assembly: how to put everything back in place

Assembling a laptop HP Pavilion - a process reverse to disassembly, but with several nuances:

1. Make sure everything cables are connected and secured with latches. Pay special attention to the touchpad cable - if it is not fully inserted, the touchpad will not work.
2. Check if there are any left foreign objects inside the case (screws, pieces of plastic).
3. Place the cover in place and begin to snap it into place. the side opposite the hinges (usually from the top).
4. Tighten the screws criss-crossto avoid distortions. Do not over-tighten them as this may cause the plastic to crack.

After assembly, turn on the laptop and check:

• 🔋 Does it work? charger (the indicator should be on).
• 🖱️ Is it functioning? touchpad and keyboard.
• 📶 Is there a signal Wi-Fi (check antenna connections).

If something doesn't work, don't panic. Return to disassembly and check the connections of the corresponding cables. In 90% of cases, the problem is solved by reconnecting.

FAQ: Frequently asked questions about HP Pavilion disassembly

Is it possible to remove the lid without a plastic spatula?

Technically yes, but the risk of damaging the latches or housing increases significantly. As a last resort you can use plastic card (for example, banking) or wooden stick, wrapped in cloth. Metal objects (knives, screwdrivers) are strictly not recommended.

What should I do if the laptop does not turn on after assembly?

First check:

1. Connection power cable to the motherboard (in models with a removable battery).
2. Reliability of fastening RAM And SSD (if you touched them).
3. Absence foreign objects under the cover, which can make contacts.

If the laptop does not respond to the power button, disconnect the battery (if possible) and try turning it on from the power supply.

How can you tell if all the lid latches are latched?

When assembled correctly, the cover should:

• sit tight, without gaps around the perimeter.
• Do not sag when pressing on the corners.
• Do not make squeaks or crunches when pressed.

If the cover is loose or there are gaps, check to see if the screws are loose or if the latches are broken.

Do I need to update the BIOS before upgrading components?

Yes, if you plan to install new processor or RAM at a higher frequency than the current BIOS version supports. For example, in some Pavilion 15 to work with DDR4-3200 BIOS version required F.10 or newer. Check compatibility on the website HP Support.

Is it possible to disassemble HP Pavilion without experience?

Yes, if you follow the instructions carefully and take your time. The main thing is do not use excessive force And record every step (photo or video). For the first disassembly, choose a simple action, for example, SSD replacement or dust cleaning, and not a complete disassembly.
