Owners of older laptop models are often faced with the need to service them. Model HP Pavilion g6, released back in the early 2010s, remains popular due to its maintainability and availability of spare parts. However, over time, the device begins to overheat, make noise, or lose performance, requiring internal intervention.
Process laptop disassembly is not difficult if you act consistently and carefully. In this article, we'll take a closer look at how to access internal components, replace thermal paste, and clean the cooler without damaging the fragile plastic latches or cables. Proper preparation and knowledge of design features Pavilion g6 will help you save time and avoid unnecessary expenses at the service center.
Preparation of the workplace and necessary tools
Before physically tampering with the device, it is necessary to create conditions that eliminate the risk of damage to the electronics. Static electricity - the main enemy of the motherboard and other sensitive components. Before starting work, be sure to touch a grounded metal object or wear an antistatic wrist strap.
You will need a set of screwdrivers. For HP Pavilion g6 Phillips screwdrivers with a fine tip (PH0 or PH1) are best, as well as a plastic pick or a special card for prying the latches. It is not recommended to use metal tools to open the case, as you can scratch the plastic or accidentally short the contacts.
Arrange the parts in the order they were removed. This is critical during assembly as screws may vary in length and diameter. If you mix them up, there is a risk of piercing the board with a longer screw or not tightening the short screw all the way, which will lead to play in the cover.
Make sure there is enough space on the table and good lighting. You will need a container to store the screws and, preferably, a bolt pattern. Take your time at this stage, since it is quality preparation that determines the success of the entire operation.
Turning off the power and removing the battery
The first and most important step is to completely de-energize the device. Removing the battery must be performed before any other action, even before unscrewing the screws on the case. On the model Pavilion g6 The battery locking mechanism has its own characteristics that you need to know in advance.
Turn your laptop upside down. On the side or bottom you will find the battery lock slider. You need to slide it to the unlocked position and then remove the battery. Be careful that if the slider sticks, do not use excessive force or the plastic retainer may break.
After removing the main battery, it is necessary to discharge the residual voltage in the capacitors. To do this, press and hold the power button power button within 15-20 seconds. This action ensures that there is no charge left in the system that could cause a short circuit when the contacts touch.
It is also worth checking for the presence of a built-in battery or additional batteries, although in this model they are usually external. Make sure the power supply is unplugged and the cord is unplugged from the laptop. Working with the device under voltage is strictly prohibited.
⚠️ Attention: Never try to disassemble a laptop if the battery is swollen. In this case, there is a risk of fire due to mechanical impact. First, safely dispose of the old battery.
Removing the bottom cover and unscrewing the screws
After removing the battery, we proceed to removing the bottom cover. In the model HP Pavilion g6 the screws are fixed in different places. Some of them are located under stickers with information about the serial number, and some are in special recesses for rubber feet.
Carefully inspect the bottom. You need to unscrew all visible screws. If there is a screw under the sticker, carefully pry the edge of the sticker with a utility knife and remove it. Don’t be afraid to damage the sticker, the main thing is to gain access to the fasteners. After unscrewing the screw, the sticker can be glued back or replaced.
Use a plastic spatula to pry off the lid. Start at the corner opposite the display hinges. The plastic latches fit quite tightly, so move around the perimeter, gradually unsnapping the latches. Do not use brute force to avoid breaking the fragile clips.
When all latches are released, the cover can be removed easily. Set it aside in a safe place. Now you can see the internal structure: cooling system, hard drive, RAM and motherboard. Pay attention to the location of the screws, as some of them may be hidden under the metal plates.
☑️ Check before removing the cover
It is important to understand that at this stage we are not yet disabling internal loops, but only freeing access to the main nodes. If your goal is only to replace the RAM, then further disassembly may not be necessary. But to clean the cooling system it is necessary.
Removing the cooling system and replacing thermal paste
The heart of the maintenance process is working with the cooling system. B HP Pavilion g6 uses a copper tube and a radiator with a fan. Over time, the thermal paste dries out into a hard crust, which blocks heat dissipation.
To access the radiator, you need to unscrew the screws that secure the cooling system to the processor and video card. Pay attention to the markings on the radiator housing or on the screws themselves (numbers 1, 2, 3). Unscrewing must be done in reverse marking order (from 3 to 1) to avoid distortion of the chip cover.
After unscrewing the screws, carefully lift the radiator. If it's stuck, you can rock it slightly from side to side, but don't jerk it too hard. Disconnect the fan connector from the motherboard by pressing the latch or simply pulling the connector. The entire system can now be removed.
Now you need to clean the old thermal paste. Use cotton swabs soaked in isopropyl alcohol. Thoroughly clean the surface of the processor and the copper base of the heatsink. Do not leave lint from the sticks. Apply a thin layer of new thermal paste using a plastic spatula or the edge of a card.
Reinstalling the radiator requires the same care. Fasten the screws according to the markings 1 to 3 to ensure even pressure. Do not tighten the screws all the way at once, do it gradually, crosswise. This will ensure perfect contact between the chip and the heatsink.
⚠️ Attention: When removing the cooling system, make sure that you do not damage the cable going to the fan. It often runs very close to the radiator mounting screws.

Memory and hard drive access
RAM modules in HP Pavilion g6 located under a separate cover or immediately under the bottom panel, depending on the revision of the case. If you remove the bottom cover completely, you will see the SO-DIMM slots. To replace memory, you just need to move the latches on the sides of the slot, and the module will jump up on its own.
The hard drive (HDD) is located in a separate compartment, often covered with a metal frame. To remove it, you need to unscrew one screw securing the frame and gently pull the plastic tab. The drive is connected via a SATA interface, which can be fixed or removable.
If you are planning to replace your HDD with a modern SSD, make sure that the selected drive is 2.5 inches in size. Transferring the system to an SSD will give a noticeable increase in operating speed, even on an old laptop. This is one of the most effective upgrades for this model.
When handling the hard drive, avoid shocks or falls. The disc mechanics are very sensitive to vibrations. If you plan to store data on the old drive, make a full backup before removing it. Any careless movement may result in data loss.
Features of working with the motherboard and cables
If you need a complete motherboard replacement or complex repair, you will have to remove it completely. This requires disconnecting many cables: keyboard, touchpad, display, speakers. On HP Pavilion g6 connectors often have latches that must be lifted up before removing the cable.
Be extremely careful with the display cable. It passes through the hinges of the case and breaks very easily if the cover is removed incorrectly. If you remove the matrix, be sure to unscrew the hinges and carefully remove the cable from the body without making sudden movements.
The motherboard is secured with many screws, some of which may be hidden under plastic covers. Before unscrewing all screws, make sure that you have disconnected all cables and connectors. Failure to remove a screw often means there is a hidden fastener or the sequence is mixed up.
When reassembling, check each step. Make sure that all cables are inserted all the way and that the latches are latched. A loose speaker or keyboard connector may result in the laptop not turning on or responding to pressure.
What to do if the screw is broken?
If the screw head is stripped, you can try using a rubber band by placing it on the screw and tightening it with a screwdriver. In extreme cases, special extractors or drilling out a screw are used.
| Component | Mounting type | Disassembly Features | Recommendations |
|---|---|---|---|
| RAM | Plastic clips | Access via separate window or cover | Ground yourself before touching modules |
| Hard drive | Metal frame + 1 screw | SATA slot, often with a plastic tab | Avoid shock when removing |
| Cooling system | 4 screws with markings | Copper tubes soldered to the radiator | Shoot in order 3-2-1, put in 1-2-3 |
| Motherboard | Lots of screws | Lots of cables, including display | Disconnect cables before unscrewing screws |
⚠️ Attention: If you are not confident in your abilities when disconnecting the display cable, it is better not to take risks. A damaged cable may require replacing the entire top cover, which is expensive.
Final assembly and performance check
After all necessary operations have been completed, the assembly stage begins. Proceed in reverse order. First install the motherboard, connect all cables and secure with screws. Then install the cooling system, hard drive and memory modules.
Before closing the bottom cover, check to see if there are any extra screws or tools left inside the case. Make sure all lid latches are in place and not broken. Put the lid on and gently press it around the perimeter until it clicks.
Reinstall the battery, making sure it is securely seated. Connect the power supply and press the power button. If the laptop boots into the system, congratulations, disassembly was successful. Check the CPU temperature using utilities like HWMonitor or AIDA64.
Pay attention to the operation of the fan: it should turn on smoothly, without any extraneous sounds. If the noise remains, the fan bearing may be worn and needs to be replaced. Also check the operation of the keyboard, touchpad and all USB ports.
Before fully reassembling, you can run the laptop without the bottom cover to check if it turns on and doesn't immediately overheat. This will help avoid repeated disassembly.
Regular maintenance will extend the life of your laptop. Even simply replacing thermal paste can reduce the temperature by 10-15 degrees, which will significantly extend the life of components. Don't be afraid to disassemble equipment as long as you do it wisely and carefully.
The main purpose of disassembly is not just to remove the cover, but to ensure reliable contact between the chips and the radiator, as well as free air flow through the cooling system.
How long does it take to completely disassemble an HP Pavilion g6?
For an experienced user, complete disassembly with cleaning and replacement of thermal paste takes about 40-60 minutes. For a beginner, this process can take 1.5-2 hours, since it will take time to study the design and carefully disconnect the cables.
Do I need to change thermal paste every time I disassemble?
It is recommended to change thermal paste every 2-3 years of active use, even if the laptop does not overheat. Over time, the paste loses its properties. If you disassemble a laptop to clean dust, replacing the paste is mandatory, since the old layer no longer provides heat dissipation.
What to do if the screws on the bottom cannot be unscrewed?
If the screw does not budge, it may be stuck or have varnish applied to it. Use a good quality screwdriver of the correct size, pressing firmly. You can put a drop of penetrating lubricant (WD-40) on the threads, but be careful not to get any liquid inside the housing.
Is it possible to replace HDD with SSD in HP Pavilion g6?
Yes, the laptop supports installing a 2.5-inch SSD. This is a simple operation that does not require special skills. After installing the SSD and transferring the system, the speed of the device will increase significantly, which will give a second life to the old laptop.
How to properly clean a radiator from dust?
It is best to use compressed air from a can or compressor. Blow through the radiator openings, having previously fixed the fan blades so that it does not rotate due to the air flow. This will prevent damage to the fan bearing.
