Owners of laptops of the line HP Pavilion g series often face the need for upgrades or repairs that require access to internal components. These devices, despite their age, remain popular due to their simple design and availability of spare parts. However, incorrect actions can lead to damage to fragile cables or plastic latches of the case.
Disassembly HP Pavilion g4, g6 or g7 is a process that requires patience and accuracy. Unlike modern ultrabooks, there are many different types of screws and specific fasteners used here. If you are planning to replace hard drive on an SSD or clean the cooling system from dust, you will have to remove the top cover and keyboard.
Many users mistakenly believe that it is enough to simply unscrew the screws on the bottom. In fact, access to the motherboard often requires removing the keyboard, which is the most difficult stage of the work. Incorrect prying can break the latches, which in this series of laptops are made of rather fragile plastic.
Preparation of the workplace and necessary tools
Before you start disassembling a laptop, it is necessary to organize a safe space. You'll need a clean, well-lit table with a hard surface to prevent small parts from falling through the cracks. Be sure to turn off HP Pavilion from the mains and remove the battery, since working with internal components while the power is connected is unacceptable.
A specialized set of screwdrivers will become your main assistant. Phillips-head bits PH0 and PH1 are ideal for this series, as well as a flat-head screwdriver for carefully prying up the latches. Don't forget to wear an antistatic wrist strap or at least periodically touch a grounded metal object to remove static charge from your hands.
In addition to tools, prepare containers for sorting screws. In the building HP Pavilion g6 The screws are of different lengths, and if you screw a long screw into a short hole, it may puncture the motherboard. Lay out the fasteners in the order in which you remove them, or label the cells of the box.

Removing the bottom cover and dismantling the main components
Begin the process by removing all visible screws on the bottom cover of the case. Please note that some screws may be hidden by rubber feet or serial number stickers. After unscrewing all the fasteners, turn the laptop over and begin to carefully pry off the cover with a plastic card or mediator.
In line HP Pavilion g series the lid is often held in place by multiple hidden latches around the perimeter. Move the tool along the joint, hearing the characteristic clicks of the latches being released. Do not apply excessive force in one place as the plastic may crack. After removing the cover you will have access to the modules RAM and hard drive.
If your goal is to replace RAM or disk, you can stop at this stage. To remove the disk, simply unscrew one fastening screw and carefully slide it out of the slot. The memory modules are held in place by metal brackets that need to be bent to the sides, after which the bar itself will jump out at an angle of 45 degrees.
⚠️ Attention: When removing the bottom cover, be extremely careful with the touchpad cable. It passes through a hole in the metal partition and can break if the lid is opened suddenly.

Removing the keyboard and top panel
This stage is considered the most critical in the disassembly process HP Pavilion g4 or g7. The keyboard is held in place not only by screws, but also by a complex system of clamps under the top frame. First you need to unscrew the two screws located in the battery compartment that secure the keyboard from the bottom.
Turn the laptop over and look for thin gaps between the keyboard and the top panel. Insert a plastic spatula into these slots and slowly move along the row of keys. You will feel the latches snap open. Take your time, as the keyboard cable is very short and fragile.
Once the entire keyboard is unfastened, do not immediately turn it upside down. Gently lift the front edge and locate the cable that goes to the motherboard. Open the connector lock and remove the wire. Only then can you completely remove the keyboard from the case.

Access to the cooling system and motherboard
Removing the keyboard and top frame will give you access to the motherboard and cooling system. This is necessary for replacement thermal paste or cleaning the radiator from dust. First, disconnect all cables going to the board: from the touchpad, USB ports, display and speakers.
Pay special attention to the fan connector. Its latch is very fragile, so you need to pry it off very carefully. After disconnecting all cables, unscrew the screws securing the heatsink to the processor and video card. Remember the unscrewing order, as it can affect the uniform pressure of the cooling system.
To remove the motherboard, you will need to remove a number of other elements, such as the optical drive and touchpad. Some models HP Pavilion g series The touchpad screws are hidden under stickers. Be prepared that the process may take considerable time due to the abundance of small parts.
⚠️ Warning: Never remove the heatsink screws unless they are disconnected from the motherboard. A sudden movement may tear out the connectors located under the heatsink.
How to properly apply new thermal paste?
Remove the old layer of paste with alcohol, apply a pea-sized drop of new paste to the center of the processor and gently press the heat sink so that the paste is distributed evenly without bubbles.
Assembling the device and checking its functionality
Assembly is carried out in the reverse order, but observing a number of important nuances. Before screwing on the heatsink, make sure the processor and heatsink pads are clean and coated with fresh thermal paste. Incorrect installation of the cooling system will lead to overheating and throttling of the processor.
When connecting cables, pay attention to their orientation. If the cable is inserted crookedly, there will be no contact, or you may damage the connector. Close the connector latches until you hear a characteristic click to prevent accidental disconnection during vibration or transportation.
After complete assembly, connect the battery and power, but do not rush to turn on the laptop. First, visually check that all the screws are in place and nothing is sticking out of the case. Turn on the device and go to the BIOS to check that the components are detected correctly and there are no errors.
- ✅ Check the cleanliness of the contacts before assembly
- 🔌 Make sure all cables are tightly connected
- 🧊 Apply thermal paste in an even layer
Before complete assembly, it is recommended to connect the power and check the functionality of the keyboard and touchpad without closing the case completely.
