Disassembly of brand laptops HP - this is a procedure that requires care and precision, since the design of many series has its own unique features. Users often face the need to replace a drive or add RAM, but are afraid of damaging flimsy latches or breaking cables. Unlike older models, modern HP Pavilion or ProBook equipped with hidden fasteners that are easy to miss at first glance.
Incorrect force when removing the cover can lead to the formation of cracks in the case, which will significantly reduce the aesthetics of the device and its value during future sale. We will analyze in detail the algorithm of actions for various lines so that you can safely access the internal components. It is important to understand that each episode, be it Spectre, Envy or budget 15-cb, has its own fastening nuances.
Preparation of the workplace and necessary tools
Before starting any physical impact on the case, it is necessary to ensure conditions that exclude static electricity and loss of small screws. The work surface should be level, clean, and well-lit so that you can see the marks on the screws and the position of the latches. The absence of an antistatic wrist strap can be compensated for by touching the unpainted metal part of the battery or case before starting work.
You will need a set of screwdrivers with magnetic bits, as screws in laptops HP often have a specific shape and easily roll onto the floor. Use a Phillips head screwdriver PH0 or PH00, depending on the size of the fastener. A plastic card or mediator is useful for carefully prying up the latches; metal objects should absolutely not be used due to the risk of damaging the tracks on the board.
- 🛠️ Magnetic mat for sorting screws by size
- 🔧 Precision screwdriver set
PH0AndPH00 - 🪙 Plastic card or pick for removing latches
- ⚡ Antistatic wrist strap or frequent grounding
Sometimes the screws are hidden under rubber feet or labels. If you see a sticker covering the screwdriver recess, carefully pry up the edge of the sticker. It is important not to break the warranty seal if the device is still under warranty, otherwise the service center may refuse free repairs.
Basic Power Off and Battery Removal Procedure
The most critical stage is completely de-energizing the device. Most modern laptops HP The battery is built into the case, so it cannot be simply pulled out, as in older models of the series Compaq. You will need to disconnect the battery connector from the motherboard after removing the back cover, but first you need to unplug the device and turn it off with the button.
If you have a model with a non-removable battery, disconnecting the connector is the only guarantee that an accidental short circuit will not burn out VRM or chipset. In some cases, for example in the series ZBook, you need to remove the keyboard to access the battery, but this is the next level of disassembly. For standard Pavilion Just unscrew all the screws and remove the bottom panel.
⚠️ Warning: Never attempt to remove the cover while the laptop is plugged in or in sleep mode. Even a laptop that is unplugged can retain residual voltage in the capacitors, which is dangerous for electronics.
After removing the cover, the first thing to do is find a wide cable or connector going from the battery to the board. Gently pry it out with a plastic spatula. Do not pull on the wire itself, only pull on the plastic housing of the connector. After disconnecting the battery, you can proceed to further manipulations with the memory or drive.

Algorithm for unscrewing screws and searching for hidden fasteners
Screw assembly HP often has hidden elements. In the series 15-dw or 15s The screws can be hidden under rubber feet in the corners of the case. You will have to carefully peel them off to get to the fasteners. Use a thin tool to avoid tearing the rubber, otherwise it will lose its shock-absorbing properties.
Some models such as HP EliteBook, have screws with colored marks or special heads. Pay attention to the markings on the bottom panel: often the manufacturer indicates the number of screws and their location. If the screw does not come out, do not apply excessive force; check to see if it is hidden under the serial number sticker.
- 🔍 Inspect the corners of the case under the rubber feet
- 📄 Check the warranty information stickers for holes
- 🔩 Use a magnetic screwdriver to hold the screws
If you see a screw that looks different than the others, check the documentation for your model. In some cases this is a screw to access SSD without removing the entire cover. Do not unscrew it if you plan to change only the RAM, so as not to damage the integrity of the case.
☑️ Preparing to remove the cover
The process of removing the plastic back panel
When all the screws are unscrewed, the most important stage begins - removing the cover. The pinching elements (clips) are located around the perimeter of the case and often have a gap of only 1-2 millimeters. Insert the plastic card into the slot between the top and bottom of the case and slowly slide it along the edge.
An audible clicking sound is normal when plastic clips come loose, but it should not be loud or sharp. If the clip does not budge, check whether you forgot to unscrew the screw in another place. Violence will cause the clip to break, causing the cap to become loose or not seal properly.
Pay special attention to the areas around ports and hinges. In models HP Omen plastic latches are often located there, as this is a high-stress area when opening the lid. Move smoothly, without tearing off the cover abruptly, so as not to break the cables that may be connected to the board through the back panel.
What to do if the clip breaks?
If you break the plastic retainer, don't panic. The cover can be secured with a screw in this place or you can use special glue for plastic. The key is to ensure a tight seal for cooling and dust protection.
⚠️ Attention: Some models HP Spectre The touchpad or speaker cable passes through the back cover. Open it very slowly and immediately check that there is no tension on the wires before removing the panel completely.
Once all the latches are released, lift the lid and turn it over. Carefully disconnect the cables, if any. They are usually secured with metal locks that need to be lifted up or to the side. Do not pull on the wires; use a plastic spudger to release the lock.
The main mistake beginners make is trying to tear the cover off the body without first snapping off all the clips around the perimeter, which leads to cracks in the plastic.
Features of disassembling gaming and ultrabook rulers
Gaming laptop series HP Omen And Victus have a more complex cooling design, so the back cover often contains ventilation ducts. The screws here can be longer and the clips more massive. It is important to follow the unscrewing sequence so as not to deform the housing under the pressure of the cooling system.
In ultrabooks Spectre And Envy An adhesive connection between the lid and the body is often used. In such cases, it is necessary to use a plastic card and slowly cut through the adhesive layer. Sometimes using a hairdryer is necessary to soften the adhesive, but do so with caution so as not to overheat the components inside.
The table below shows the features of various series that will help you navigate before starting work.
| Laptop series | Mounting type | Features of dismantling |
|---|---|---|
| Pavilion / 15s | Screws + clips | Screws under rubber feet |
| ProBook / EliteBook | Screws + clips | The presence of marks on the screws, access to the SSD without removing the cover |
| Spectre / Envy | Glue + clips | Care required when peeling off, possible adhesive streak |
| Omen / Victus | Screws + powerful clips | Long screws, complex ventilation system |
Ultrabooks often have more fragile display cables that run through the hinges. When removing the back cover, make sure the laptop is closed to avoid straining these wires. In gaming models, it is important not to damage the radiators, since they can be mounted on the rear panel.
Before completely removing the cover, take a photo of the internal layout on your phone so that when assembling you don’t forget where to connect each cable.
Common mistakes and ways to prevent them
The most common mistake is using metal tools to pry the lid. This inevitably leads to scratches on the case and the risk of puncturing the motherboard. A plastic card is your best friend in this process. If the clip doesn't budge, go back to looking for hidden screws.
Another common problem is loss of screws. They may be different sizes, and if you mix them up, you may damage the threads or cause the lid to not fit properly when reassembling. Use a magnetic mat or draw a diagram of the screw locations on a piece of paper.
- ❌ Do not use magnetic screwdrivers near hard drives (HDDs)
- ❌ Do not pull the cable cables when disconnecting
- ❌ Do not leave the cover unsupported when disconnecting cables
If you feel the lid won't open, stop and check to see if you forgot to remove the screw in the hinges or under the sticker. Strength is no help here; it will only break the plastic. In 90% of cases the problem is a missing hidden screw under the rubber foot.
