Owners of laptop series HP Pavilion And HP ProBook often face the critical problem of unstable wireless network operation. In most cases, the culprit is the model’s built-in Wi-Fi adapter RTL8723DE, which is known for its software glitches and physical overheating.
Solving this problem does not always require a complete replacement of the entire device. Often it is enough to simply remove the faulty module and replace it with a more reliable analogue or update the firmware, after first gaining access to the internal components. The process of dismantling the case requires care, since modern laptops HP equipped with fragile plastic latches.
In this article we will take a closer look at how to properly disassemble a laptop. HP to access the slot M.2where the adapter is installed RTL8723DE. You will learn about the necessary tools, sequence of actions and typical errors that can lead to damage to the motherboard.
Preparing the workplace and necessary tools
Before you begin the disassembly process, it is essential to establish a safe workspace. Static electricity is the biggest enemy of electronics, so before touching internal components, motherboard It is necessary to remove the static charge from your hands.
You will need a set of screwdrivers with thin bits, preferably magnetic, so as not to lose small screws inside the case. A plastic mediator card or a special spatula is also useful for carefully prying off the covers without scratching the plastic.
Do not forget to prepare an antistatic wrist strap or at least periodically touch the metal part of the battery or radiator to equalize the potential. Ignoring this rule can lead to instant failure chipset or memory module.

Complete power off and removal of external drives
The most critical stage of any work with electronics is the guaranteed shutdown of the power source. Even if the laptop is turned off, the residual voltage in the capacitors may be sufficient to cause a short circuit when removed.
First, turn off the device through the operating system and unplug the power adapter cable from the outlet. Next, check to see if the system has sleep or hibernation enabled, as this may hide the actual power status.
⚠️ Attention: If on a laptop HP a non-removable battery is used, do not under any circumstances try to dismantle it until the cable is completely disconnected from the motherboard, otherwise the risk of damage to the power controller increases significantly.
After turning off the external power, you must disconnect the internal battery. Most models HP with adapter RTL8723DE The battery is located under the bottom cover and is connected via a wide flat connector.
- 🔌 Disconnect the power cable from the network
- 🔋 Disconnect the battery cable from the motherboard
- 💾 Remove all flash drives, disks and memory cards
Removing the bottom housing cover
Most laptops HP series Pavilion Gaming or Acer (with which this problem is often confused, although we are talking specifically about HP) have screws hidden under rubber feet. You will have to carefully peel them off to get to the fasteners.
Use a plastic spatula to go around the perimeter of the lid and release the latches. The movements must be smooth, without excessive force, otherwise the fragile plastic will crack and the case will lose its seal.
Once all the latches are released, the cover will come off. Do not rush to lift it up immediately, since thin cables from the keyboard or touchpad may be connected to the case.
☑️ Opening tools
If you feel resistance when removing the cover, stop immediately and check to see if you forgot to remove one of the screws hidden under the stickers or rubber pads.
Where to look for hidden screws?
Often the screws are hidden under a serial number (SN) sticker or under rubber feet in the corners of the case. Check all surfaces thoroughly.
Battery disconnection
Now that the case is open, first find the connector connecting the battery to the motherboard. Typically this is a wide white connector with several pins located in the central or side part of the board.
Gently pull on the plastic connector, not the wires themselves, to avoid breaking them. If the connector is tight, use a plastic spatula to lift it up slightly.
After disconnecting the battery, wait about 15-20 seconds. This time is necessary to completely discharge the residual voltage in the system and reset the power management logic.
⚠️ Caution: Do not touch the battery connector contacts with metal objects, as this may cause a short circuit even with a discharged battery.
Only after completing this step can we consider that the laptop is completely de-energized and ready for further repair or replacement of components.
Before disconnecting the battery cable, take a photo of its location with your phone so that during assembly you do not confuse the direction of connection.
Localization and dismantling of the RTL8723DE Wi-Fi module
Adapter RTL8723DE usually installed in slot M.2 2230 and secured with one screw. It is located on the top of the laptop, often next to the processor cooling system.
The adapter has two thin antenna wires attached to it: black and gray (or white and black). They need to be carefully disconnected by pressing on the connectors and pulling them up. Do not pull on the wires or you will break the inner copper core.
After disconnecting the antennas, unscrew the single screw holding the module in place. Under its pressure, the adapter will rise slightly at an angle, and you can carefully pull it out of the slot.

- 🔩 Unscrew the module fixing screw
- 🚀 Remove the adapter from the M.2 slot
If you plan to replace the adapter with a more powerful one, for example Intel AX200, make sure that your BIOS does not have a whitelist blocking other models.
Correctly disconnecting the antennas is the key to Wi-Fi operation after assembly. Damaged connectors require complete module replacement.
Assembly and performance testing
The assembly process is a mirror image of disassembly, but requires even more care. Install the new or old module first RTL8723DE into place and secure it with a screw.
Reconnect the antennas, making sure they snap into place. It is best to lay the wires in standard channels or secure them with tape so that they do not interfere with the closing of the lid.
Before final assembly, you can temporarily connect the battery and turn on the laptop to check if the system sees the new adapter. If everything works, turn off the device, disconnect the battery and reassemble the case.
