We disassemble an HP laptop to replace the RTL8723BE Wi-Fi module: a detailed guide

Module RTL8723BE - a popular Wi-Fi/Bluetooth adapter that was installed in many laptop models HP 2013–2018 (series Pavilion, ProBook, EliteBook etc.). Its replacement may be necessary if the network connection is unstable, there is no Bluetooth signal, or an upgrade to a more modern standard (for example, Wi-Fi 5/6). However, disassembling a laptop is a process that requires care: one wrong move can lead to damage to cables, connectors, or even the motherboard.

In this article you will find step-by-step instructions with photos, a list of necessary tools, as well as unique nuances of disassembling specific HP models with the RTL8723BE module (for example, features of mounting antennas in HP Pavilion 15 or the location of the screws in ProBook 450 G3). We will also analyze common mistakes that users make and give recommendations on choosing a replacement so that the new adapter works without problems with drivers.

Preparing for Disassembly: Tools and Safety Precautions

Before you start disassembling, make sure you have everything you need. The absence of even one tool can turn a simple procedure into agony. Here minimum setwhich will be required:

• 🔧 Screwdriver set: cross PH00 (for most screws), flat 1.5 mm (for prying up the latches), and also torx T5 (found in some models EliteBook).
• 🧲 Magnetic mat or tray for screws - so as not to lose small parts (in HP ProBook there can be up to 15 of them!).
• 📸 Smartphone for photographing each stage. This will help you put your laptop back together properly, especially if this is your first time disassembling it.
• 🧴 Plastic picks (or guitar picks) - they will help you carefully separate the case latches without scratches.

Pay special attention electrostatic safety. Module RTL8723BE sensitive to static electricity, therefore:

• 🚫 Do not work on carpet or in woolen clothing.
• 🖥️ Connect to laptop antistatic wrist strap (or at least touch the metal case of the system unit before starting work).
• 🔌 Disconnect your laptop from the network and remove the battery (if it is removable). In models with a non-removable battery (for example, HP Spectre) this is more difficult to do - we’ll talk about this separately.

⚠️ Attention: If your laptop is under warranty, disassembling it will void it! In some countries (for example, in the EU), the law obliges manufacturers to maintain a warranty for self-repairs, but in Russia and the CIS this does not apply. Check conditions with an official dealer HP.

Determining the laptop model and location of the RTL8723BE module

Module RTL8723BE may be in different places depending on the model HP. To avoid disassembling your laptop at random, first determine its exact modification. To do this:

1. Turn the laptop over and look for the serial number sticker (usually starting with the letters 5CD, 5CG or 2AN).
2. Enter your serial number on the website HP support — the full model will be indicated there (for example, HP Pavilion 15-au003ur).
3. Check the location of the module in service manual (you can download it on the same site HP or on ManualsLib).

Below is a table with a typical layout RTL8723BE in popular models HP:

Laptop model	Module location	Disassembly Features
HP Pavilion 15 (series au, ab)	Under the bottom cover, next to the RAM	You need to remove 11 screws and carefully snap off the cover (the latches are fragile!)
HP ProBook 450 G3/G4	Under the keyboard, to the right of the cooler	You need to remove the keyboard (unscrew the 3 screws from the bottom and disconnect the cable)
HP EliteBook 840 G3	Under the back cover, under the metal screen	Screws under rubber feet! The cover is secured with latches + 2 hidden screws
HP Envy 13	Under the bottom panel, next to the SSD	The case is adhesive! You will need a hair dryer to soften the glue.

If your model is not in the table, use universal rule: module RTL8723BE usually located near the antenna wires (the thin black or white cables that go to the screen cover). In 90% of cases it is located under the bottom cover of the laptop, but in ultrabooks (for example, HP Spectre x360) may require complete disassembly.

Step-by-step disassembly of an HP laptop: remove the bottom cover

Let's start with the simplest option - disassembling a laptop with a module RTL8723BE located under the bottom cover (for example, HP Pavilion 15 or HP 250 G5). Follow the instructions strictly in order:

1. Unscrew all screws on the bottom cover. Please note:
   • 🔹 Screws can be of different lengths! Remember where each one stood (for example, in HP ProBook 4 screws are shorter than the others).
   • 🔹 In some models, the screws are hidden under rubber feet - carefully pry them off with a flat screwdriver.
2. Disconnect the latches around the perimeter of the lid. Use a plastic pick:
   • 🔹 Start in the corner next to the screen hinges - the latches are weaker there.
   • 🔹 Move the pick along the seam until the lid begins to rise.
   • 🔹 Don't use force! If the cover does not budge, check that all screws are unscrewed.

Remove the cover and set it aside. Now you will see the insides of the laptop: motherboard, cooler, battery (if non-removable) and, most likely, the module itself RTL8723BE.

This is what the module looks like RTL8723BE in a typical laptop HP:

⚠️ Attention: In models HP Omen and some Pavilion Gaming under the cover there may be an additional metal screen covering the module. It needs to be unscrewed separately (usually 2-3 screws). Don't confuse this screen with a cooler!

Removing the RTL8723BE Module: Antennas, Mounts, and Traps

Now that you have reached the module, you need to carefully remove it. There are several here critical momentswhich often lead to breakdowns:

1. Disconnect the antennas:
   • 📡 Antenna cables (MAIN And AUX) are attached to the module with small connectors U.FL. Gently pull the black plastic connector housing upwithout pulling the wire!
   • 🔧 If the connector does not give in, use tweezers, but do not use force - you can tear off the soldered contacts.
2. Unscrew the screw securing the module:
   • 🔩 Usually this is a screw PH00 with a spring washer. Don't lose it!
   • 🔩 In some models (for example, HP EliteBook 840) the screw may be under a metal plate - it must first be removed.
3. Remove the module:
   • 🖥️Grip the edges of the module and gently pull it at an angle of 30° (not straight up!). Connector M.2 2230 (into which the module is inserted) may be tight.
   • 🚫 Do not use a screwdriver as a lever - you can damage the connector on the motherboard!

If the module does not eject, check:

• ✅ Are all antennas disconnected?
• ✅ Are there hidden latches on the sides of the connector (found in HP ZBook)?
• ✅ Have you confused the module mounting screw with the motherboard mounting screw (they may be nearby)?

What to do if the U.FL connector on the antenna is broken?

If the plastic housing of the connector U.FL broke off, it can be temporarily replaced with a new one (purchased separately for 100–200 rubles). However, soldering such a connector at home is extremely difficult - it is better to contact a service center. As a last resort, you can carefully solder the antenna directly to the module contacts, but this will violate the warranty (if it is still valid).

Installing a new module: compatibility and configuration

Before installing a new module, make sure it is compatible with your laptop. Module RTL8723BE has a form factor M.2 2230 with key A+E, but not all modules with such a connector will work. Here's what to check:

• 📋 BIOS support: some laptops HP (especially EliteBook And ProBook) have whitelist (whitelist) of allowed Wi-Fi modules. If you install an unauthorized module, the laptop may not boot. Check the list of compatible modules for your model on the forums (for example, TonyMacx86).
• 🖧 Connection type: module can be PCIe or USB. RTL8723BE - this is PCIe, so replace it with USB-module (for example, RTL8188EU) will not work without an adapter.
• 📡 Number of antennas: if your new module supports MIMO 2x2 (two antennas), and the old one only 1x1, you will need to connect both antennas for maximum speed.

Recommended replacements for RTL8723BE:

Module	Wi-Fi standard	Bluetooth	Notes
Intel AX200	Wi-Fi 6 (802.11ax)	5.2	Best choice for upgrade, but may not work on whitelisted laptops
Broadcom BCM94360CS	Wi-Fi 5 (802.11ac)	4.2	Good compatibility with macOS (if you plan to Hackintosh)
Realtek RTL8822BE	Wi-Fi 5 (802.11ac)	5.0	Direct replacement, but drivers may require manual installation

After installing the new module:

1. Connect the antennas (observe the colors: MAIN usually black AUX - white or gray).
2. Tighten the fastening screw (do not overtighten!).
3. Replace the cover and all screws.
4. Turn on your laptop and check that Wi-Fi and Bluetooth are working.

⚠️ Attention: If after replacing the module the laptop does not turn on or displays an error 104-Unsupported wireless network device detected, this means that the new module is blocked by the BIOS. Solutions:

• 🔧 Update BIOS to the latest version (sometimes removes restrictions).
• 🔧 Use modified BIOS (risky, may lead to a brick!).
• 🔧 Return the old module and buy a compatible one (list can be found on BIOS-Mods).

Assembling a laptop and checking its functionality

Assembling a laptop is the reverse process of disassembling, but it has its own pitfalls. Follow these tips to avoid problems:

• 🔩 Screws: Screw them crosswise (like the wheels of a car) to avoid distortion of the lid. Start with the corner screws.
• 🧲 Latches: before finally snapping the cover, make sure that all cables and cables lie flat and are not pinched.
• 🔋 Battery: If you disconnected the non-removable battery, connect it lastwhen all the screws are already tightened.

After assembly, check:

1. Turn on the laptop and check if the system boots. If an error appears No Boot Device, you may have touched the SSD cable during assembly.
2. Check Wi-Fi and Bluetooth:
   • 📶 Connect to a Wi-Fi network and measure the speed (must match the standard of the new module).
   • 🔵 Connect a Bluetooth device (such as headphones) and check the sound.

Check the temperature: If the laptop starts to heat up more, you may have installed the cooler poorly or forgotten to connect its power.

If something doesn't work:

• 🔍 Wi-Fi won't turn on: Check if the antennas are connected (a common mistake is to confuse MAIN And AUX).
• 🔍 Bluetooth doesn't work: update the drivers manually (download from the module manufacturer's website, not from the HP).
• 🔍 Laptop won't turn on: Check if you forgot to connect the power to the motherboard (some models have a separate connector next to the cooler).

Common mistakes and how to avoid them

Even experienced users sometimes make mistakes when disassembling laptops HP. Here TOP-5 most common problems and how to prevent them:

1. Broken lid latches:

   🔹 Reason: Trying to open the cover without removing all screws or using metal tools.

   🔹 Solution: Use only plastic picks and check all screws (including those hidden under the legs).

2. Torn antenna cables:

   🔹 Reason: pulling the wire instead of the plastic connector U.FL.

   🔹 Solution: Grab only the black housing of the connector and pull straight up.

3. Short circuit:

   🔹 Reason: Working without an antistatic wrist strap or touching the motherboard with metal tools.

   🔹 Solution: Before working, touch a grounded object (for example, a radiator).

4. Incompatible module:

   🔹 Reason: purchasing a module without checking BIOS compatibility.

   🔹 Solution: Look for information about the whitelist for your model on forums (for example, NotebookReview).

5. Lost screws:

   🔹 Reason: chaotic storage of screws during disassembly.

   🔹 Solution: Use a magnetic mat or stick a screw pattern onto a piece of paper.

If you do make a mistake, don't panic. In most cases the problem can be solved:

• 🔧 Broken lid latch: You can seal it with superglue or replace the lid (costs 500–1500 rubles).
• 🔧 Torn antenna connector: buy a new connector U.FL and solder (or contact service).
• 🔧 Incompatible module: return the old one RTL8723BE and buy a proven analogue.
