Proper disassembly allows you to extend the life of your device by several years without contacting a service center. In this article we will look in detail at the process of removing the back cover, accessing the internal components and subsequent assembly. The main thing is to act carefully and have the necessary tools on hand to prevent mechanical damage.
Preparing the workplace and necessary tools
Before you begin physical impact on the body, you need to create the right conditions. The work surface should be level, clean and spacious enough so that the laid out screws do not get lost. Lighting is critical as you will have to work with small details and traces that are difficult to see in dim light.
You will need a screwdriver set containing Phillips bits PH0 and PH1. It is also necessary to have a plastic mediator card or a special spatula for prying off the lid. It is better to exclude metal objects to avoid accidental short circuits or scratches on the case.
- 🛠️ Phillips screwdriver with magnetic tip for easy gripping of screws.
- 🔋 Antistatic bracelet or at least touching a grounded metal object.
- 📱 Flashlight or table lamp with cool white light for better visibility.
- 📦 Container with cells for sorting screws by size and installation location.
Turning off the power and removing the back cover
The most important stage is the complete de-energization of the system. Turn off the laptop through the operating system and unplug the power supply from the outlet. Then press and hold the power button for 15-20 seconds to discharge any residual voltage in the motherboard capacitors. This will prevent the device from accidentally starting during operation.
Next, turn the laptop over and find the screws that secure the bottom cover. In models HP Pavilion they are often hidden under rubber feet, which will have to be carefully pryed off. Make sure you remove all screws, including those in the recesses, as even one screw left may prevent the cover from being removed.
☑️ Preparation for disassembly
After removing the screws, use a plastic spatula to separate the top and bottom of the case. Start moving from the corners, moving around the perimeter until you hear the characteristic clicks of the detachable latches. Do not use excessive force as the plastic may crack and the latches may break off.
⚠️ Attention: In some versions HP Pavilion the battery is connected to the motherboard via a cable, which can be hidden under a metal frame. Be sure to turn it off immediately after removing the cover to avoid short circuits during further operation.
Access to memory modules and storage
Once the cover is removed, you are presented with a view of the internal components. First, find the random access memory (RAM) modules. They are usually located in slots at an angle of 45 degrees or horizontally, depending on the specific revision of the board. To remove it, you need to carefully move the metal clips along the edges of the slot to the sides.
The memory module itself will pop up at an angle, after which it can be easily pulled out with your fingers. When installing a new module, ensure that the notch on the pad aligns with the tab in the slot. Insert the bar until the latches make a characteristic click to ensure reliable contact.
- 💾 RAM: check frequency and type compatibility (DDR4 or DDR5).
- 💿 Storage: most often this is an M.2 NVMe SSD, secured with one screw.
- 🔌 Trains: be extremely careful with flat trains, they are very fragile.
- M.2 NVMe SSD
- 2.5 SATA SSD/HDD
- Combined option

Replacing thermal paste and cleaning the cooling system
Heat management is a critical aspect of any laptop's performance. Over time, the thermal paste dries out and the heatsink becomes clogged with dust, which leads to overheating and throttling of the processor. Access to the cooling system often requires unscrewing the screws holding copper pipes and fans in place and carefully lifting them up.
It is better to clean the radiator with compressed air, blowing through the cells on both sides. If possible, remove the fan completely and clean the blades with a soft brush. Remove old thermal paste with a lint-free cloth soaked in isopropyl alcohol until the surface is perfectly clean.
⚠️ Attention: Never try to remove the fan if it is glued to the radiator with a factory thermal pad. Use force to separate them carefully, otherwise you may damage the fan motor bearing.
Apply a small amount of thermal paste (about the size of a pea) to the center of the processor. When you clamp the cooler, it will distribute itself evenly, the main thing is not to overdo it so that it does not leak onto the contacts of the motherboard.
Comparison of HP Pavilion models by disassembly difficulty
Not all models in the series HP Pavilion identical in terms of component availability. Some versions have a more sophisticated design that allows parts to be replaced without completely removing the housing, while others require a more complex procedure. Understanding the differences will help you estimate the amount of work ahead of you.
The table below shows the main differences in the design features of popular generations. Pay attention to the location of the screws and the type of battery mounting.
| Model | Cover fastening type | Battery Access | Difficulty in disassembling |
|---|---|---|---|
| HP Pavilion 15-cs | Screws + latches | Cable under the cover | Average |
| HP Pavilion 15-eg | Screws (hidden under the legs) | Separate compartment | Low |
| HP Pavilion Gaming 15 | Lots of screws, metal frame | Flex cable + screws | High |
| HP Pavilion Aero 13 | Ultra-thin body, fragile latches | Built-in | Very high |
Features of the HP Pavilion Aero 13 model
This model is characterized by extreme lightness, which is achieved through the use of magnesium alloy. The lid is held on by very tight latches, and if you pry it off carelessly there is a risk of bending the body. It is recommended to use a special plastic tool with a thin edge.
Assembly sequence and performance check
Assembly is carried out in reverse order. First, connect all the cables, making sure that they are inserted all the way and that the latches click into place. Then, carefully route the wires so that they do not block any vents or touch hot components.
Before tightening all the screws, check if you forgot to connect the battery or if the cables are twisted. Temporarily turn on the laptop without closing the lid to make sure the system starts up, the fans are spinning, and the keyboard is working. If everything is in order, turn off the device and close the case.
- 🔧 Tighten the screws crosswise to avoid skewing the lid.
- 🔍 Check that all rubber feet are in place.
- 🚀 Start the system and check the temperatures in idle mode.
The correct assembly sequence ensures that there are no extraneous sounds or vibrations when the laptop is operating. If after assembly you hear a strange hum, most likely a wire is pinched somewhere or the memory module is not fully inserted.
Common mistakes when doing DIY repairs
Newbies often make the same mistakes, which can lead to costly repairs. The most common problem is using the wrong screwdriver, which leads to the screw slots slipping off. If the screw is tightened tightly, do not try to unscrew it with force, use an extractor or carefully drill out the head.
Another mistake is ignoring the markings of the loops. There are often inscriptions on the laptop case or on the cable itself indicating where it is connected. By mixing up the connectors, you can damage the controller or display.
⚠️ Attention: HP Pavilion 2020-2023 models often use a single screw to secure the SSD and a metal strip that blocks access to the M.2 slot. Do not attempt to remove the screw without first removing the metal cover, otherwise you may damage the slot.
How to unscrew a licked screw
Place a wide rubber band on the head of the screw and press the screwdriver firmly. The rubber will fill the voids and allow it to cling to the metal. If that doesn't help, use a drop of superglue on a screwdriver (carefully!) or special extractor bits.
FAQ: Frequently asked questions about disassembly
How many screws are usually in an HP Pavilion and where are they hidden?
The number of screws varies from 6 to 14 depending on the size of the diagonal. The main screws are located around the perimeter, but 2-4 screws are often hidden under rubber feet or stickers in the center of the bottom cover.
Do I need to disconnect the battery before cleaning dust?
Yes, this is required. Even if you are just planning to clean the fan, disconnect the battery cable from the motherboard. This will eliminate the risk of a short circuit if a metal object accidentally touches the board contacts.
Is it possible to replace the SSD in HP Pavilion with any other?
Technically it is possible, but you need to take into account the interface. Most modern models only support NVMe M.2. Check the length of the module (usually 2280), as some thin models may not have mounting for longer bars.
What should I do if the cover does not come off after removing all the screws?
Don't use force. You may have missed a screw under a sticker or rubber foot. Examine the case carefully in good light. If there are no screws, check to see if the latches are stuck due to dirt.
