HP Pavilion Gaming 15-cx0000 Disassembly (RAM, M.2 SSD, HDD upgrade options)

In this guide I explain how to disassemble an HP Pavilion Gaming 15-cx0000 gaming laptop, I will remove the bottom cover to access the battery, SSD, hard drive, RAM, WiFi card, heatsink, and CPU fan.

This guide will work for many different models of HP Pavilion Gaming 15-cx0008ca, 15-cx0010ca, 15-cx0020ca, 15-cx0020nr, 15-cx0030nr, 15-cx0040nr, 15-cx0042nr, 15-cx0045nr, 15-cx0049nr, 15-cx0056wm, 15-cx0058wm, 15-cx0071nr, 15-cx0077wm, 15-cx0085nr, 15-cx0086nr, 15-cx0009ne, 15-cx0026nt, 15-cx0144tx and probably some other models too.

For this disassembly, you need just a few basic tools: Torx T5 screwdriver, Phillips #1 screwdriver, case opener tool, and tweezers.

The components that can be replaced or upgraded for this notebook include the battery, memory, M.2 SSD, 2.5-inch hard disk, wireless network card, and CPU fan.

There are 7 screws on the back cover to fix it to the top cover. Use a screwdriver to remove these 7 screws, then use the case opener tool (or thin plastic tool) to slowly pry open the back cover from the top case. There are many snaps on the back cover. Be careful not to damage these snaps. Otherwise, the back cover may not be fixed to the notebook well when reinstalling it to the notebook.

After removing the back cover, we can access most of its internal components. It can be seen that the upper part includes the motherboard, fan, memory, SSD, USB board, and the lower part only has the battery and mechanical hard disk.

This is the removed back cover. There are two shock-proof sponges in the position of the mechanical hard disk. Besides, there is no special design.

This notebook comes with an 11.55v 52.5W lithium battery. In order to remove the battery, you need to disconnect the battery cable from the motherboard, and then remove all the screws that fix the battery.

It provides a 2.5-inch hard disk bay, which is fixed on the top cover by 3 screws and connected to the motherboard by a SATA cable. Some models do not have a 2.5-inch hard disk, so you can buy a SATA cable to add a 2.5-inch hard drive to your laptop.

HP Pavilion Gaming 15-cx0000 has two memory slots, one of which is equipped with 8GB Micron memory, so you can add another memory, this notebook can support up to 32GB memory.

The SSD that comes with this notebook comes from Lite-On, and there is no heat sink on the SSD. The temperature during continuous operation may be relatively high. In addition, you can see that the PCH chip also has no heat sink.

Its cooling module has two copper tubes. Although there are only two copper tubes, the power supply chips and video memory are covered.
GPU fan

The fan on the left is mainly responsible for cooling the graphics card.
CPU fan

The fan on the right is mainly responsible for cooling the CPU. You can see that there are slight differences between the two fans.
