Before starting the disassembly, power off the laptop and disconnect the power cord.

remove the back cover
There is only a screw found on the laptop’s back cover.

remove the back cover
After taking out the back cover, its internal structure can be seen. There are the memory chip, the M.2 SSD, the 2.5-inch SATA HDD, and the wireless card under the back cover. And all these components can be upgraded and replaced by the user. With this design on the back, it is more convenient for the user to get the laptop upgraded.

I will take out components one by one. First of all, remove the battery with the capacity of 56Wh. This laptop supports fast charge technology it can get fully charged quickly.

Next, take out the HDD. This HDD is made by Seagate. With the capacity of 1TB, it can meet user’s requirement on large storage capacity.

It is the M.2 (SATA) SSD from Hynix which has the capacity of 256GB. With this SSD, the user can store data and open the laptop at a faster speed.

Intel 9560NGW
The last one to be taken out is the Intel 9560NGW dual-frequency wireless card. Its speed can reach up to 1.73Gbps. Supporting 2.4GHz, 5GHz dual-frequency Wi-Fi and Bluetooth 5.0, it can bring the user more stable wireless network experience and faster Bluetooth connection.

remove screws
Now, remove all screws securing the middle frame. Taking out four screws and disconnecting clips on both sides, and then this component can be taken out.

internal structure
This is the gaming laptop’s internal structure. The keyboard and the touchpad are placed on the top. And the motherboard, other components, and the heat dissipation module are fixed in the middle frame. After taking out all the screws, we can see the motherboard.

Uncover the shield sticker on the back of the motherboard, the chipset integrated on the back of the motherboard can be seen.

remove motherboard and heat dissipation module
Removing all the screws and cables on the motherboard. The motherboard and the heat dissipation module can be taken out.

middle frame
The middle frame uses engineering plastics. The component below the middle frame which isn’t removed is the indicator module. This indicator can show the laptop’s running state in time, which makes it convenient for the user to acquire pertinent information immediately.

internal design
Its internal design aims to provide better heat dissipation performance. The merits of the design that fixing the motherboard on the middle frame are as the following: firstly, it can reduce the influence that the laptop’s high-efficient running has on the temperature of the keyboard, in this way, the user can use the laptop more comfortably; secondly, it saves room for heat dissipation. Good heat dissipation design can efficiently lower the laptop’s temperature inside to guarantee better heat dissipation performance. Lastly, this three-layer design makes its internal structure more stable and firm.

remove the heat dissipation module
After removing screws and the fan cable according to the number hint on the black heat dissipation module, the heat dissipation module can be separated from the motherboard, and the motherboard can be fully seen.

graphics card and processor
The NVIDIA GeForce GTX 1060 Max Q 6GB graphics card and the high-performance Core i7-8750H processor are stacked in the center of the motherboard.

The motherboard has good workmanship. It has a reasonable chip layout and effectively utilizes the heat dissipation module to make the chip on the motherboard get better heat dissipation.

two memory chips
Now, take out the two memory chips. They are 8GB DDR4 memory chip made by Micron. The gaming laptop provides two slots for two memory chips, which supports up to 32GB RAM. The user can upgrade the RAM by himself.

cooling fins
The blue cooling fins, the three-phase motor, the fan with 56 LCP blades and two copper pipe constitute the cooling system module.

heat dissipation module
This powerful heat dissipation module works together with the conductive strip which covering all the chips including the processor and the graphics card to guarantee the perfect performance of the processor and the graphics card. In this way, the user can enjoy a better game experience.

all the components
A copper sheet is placed under the keyboard, aiming to improve heat dissipation performance.


Until now, I have finished the disassembly of the Dell G7 15 7588 gaming laptop. From the disassembly, we can see that the G7 boasts unique internal design and high-performance heat dissipation system. With high-efficient heat dissipation performance, the 8th Core processor, the NVIDIA 1060 Max-Q 6GB graphics card, excellent workmanship, and high specification, the Dell G7 7588 is a good gaming laptop which deserves you buying, and undoubtedly it will bring the user more stable and good experience.

  1. Hi, very interesting you unbuilt of the laptop. I have a question though. Is the heatsink on this pure copper or just has a layer of copper to aluminum pipes? I want to use liquid metal on mine later on but I heard there is a risk of corroding into the aluminum. It would be nice to know that. By the way, do you plan on using liquid metal on yours? What conformal coating is recommended for this job? Thank you
