Laptops ASUS are known for their reliability, but even the highest quality equipment requires maintenance. One of the most common procedures is replacing or temporarily removing the battery. This may be necessary if it is swollen, broken, cleans the cooling system, or moves while transporting equipment. However, incorrect actions lead to damaged connectors, short circuits or even loss of warranty. In this article - step-by-step instructions for different series of ASUS laptops, including ZenBook, VivoBook, ROG and budget models, as well list of tools And critical warnings, which are ignored by 90% of users.

Features of laptops ASUS - variety of designs. In some models the battery is removable (for example, in older X550 or K550), in others - soldered into the body (as in most ZenBook or ROG Zephyrus). We will analyze both options, paying attention hidden latches, types of fastenings and how not to damage the cables. You will also find out why Removing the battery while the laptop is running may result in a BIOS reset and loss of data on NVMe drives - this nuance is rarely mentioned even in official manuals.

Preparing to Remove the Battery: Tools and Safety Precautions

Before you start disassembling, make sure you have everything you need. The minimum set of tools depends on the laptop model, but in 95% of cases it will be enough:

  • ✅ Plastic spatula (or mediator) - for separating latches without scratches.
  • ✅ Phillips screwdriver (usually PH0 or PH1) - for screws on the bottom cover.
  • ✅ Thin flathead screwdriver — for prying off removable batteries in older models.
  • ✅ Antistatic wrist strap (or at least touch a metal object) - to avoid static discharge.
  • ✅ Hair dryer or alcohol — if the battery is glued (relevant for ROG Strix And TUF).

Important: not all ASUS laptops allow you to remove the battery without complete disassembly. For example, in ASUS ZenBook UX330 or VivoBook S14 The battery is hidden under the motherboard, and removing it requires removing the cooler, drive, and even the keyboard. If you are not confident in your skills, it is better to contact a service center - especially if the laptop is under warranty.

⚠️ Attention: If your laptop ASUS equipped soldered battery (For example, ROG Zephyrus G14 or ZenBook Flip), its forced removal without special equipment can lead to power supply rupture. In such cases, it is recommended to disable the battery programmatically via the BIOS (option Disable Battery), if available.

How to determine the battery type in your ASUS laptop

Before removing the battery, you need to understand whether it is removable or not. This can be done in three ways:

  1. Visual inspection. Turn the laptop over and check the bottom cover:
    • 🔋 If there is separate cover with battery icon (often found in ASUS X550, K501) - the battery is removable.
    • 🔧 If the cover is solid, without separate hatches, the battery is most likely soldered or glued.
  • Model verification. Enter the name of your model into the search engine with the query “battery replacement”. For example: ASUS TUF A15 battery removal. Usually the first results are video demos or manuals from iFixit.
  • Diagnostics via BIOS. Go to the BIOS (usually the F2 or Del on boot) and find the section Power or Advanced. If there is an option Battery Health Charging or Disable Battery - The battery is most likely non-removable.

    • For convenience, we have compiled a table with popular models ASUS and the type of their batteries:

    Laptop series Models (examples) Battery type Difficulty of extraction
    ZenBook UX330, UX430, UX530 Soldered/glued ⭐⭐⭐⭐ (requires complete disassembly)
    VivoBook S14, S15, X512 Glued (less often soldered) ⭐⭐⭐ (need a hair dryer to soften the glue)
    ROG Strix/TUF G531, G731, FA506 Glued + screws ⭐⭐⭐⭐ (risk of damage to cables)
    Budget series X550, K550, E402 Removable (latches) ⭐ (simple)

    If your model is not included in the table, use official ASUS support site - there are often disassembly diagrams in the section Manuals & Documents.

    💡

    Before disassembling, take a photo of the location of the screws and latches on the phone. This will help put the laptop back together correctly, especially if the screws are of different lengths (as in ROG Zephyrus).

    Step-by-step instructions: removing a removable battery (using the example of ASUS X550)

    If your laptop belongs to the budget series (X550, K550, E402 etc.), most likely the battery is removable. The process takes no more than 5 minutes, but requires accuracy.

    Turn off the laptop and disconnect the charger|

    Turn the laptop over onto a flat surface|

    Wear an antistatic wrist strap or touch metal|

    Prepare a plastic spatula or thin screwdriver-->

    1. Turn off the power. Turn off the laptop, take out the charger and wait 1-2 minutes - this is necessary for the capacitors on the motherboard to discharge.
    2. Locate the battery clamps. The bottom cover should have:
      • 🔒 Two latches (usually marked as Battery Lock or with a lock icon).
      • 🔧 Screw (in some models, for example ASUS K750).
  • Pull back the latches. Slide them into position Unlock (usually in the direction of the arrow). If the latches are tight, use a plastic spatula, but do not use too much force as they may break.
  • Pry up the battery. Gently pull the battery up using the special notch. If it does not budge, check that all latches are disengaged.
  • Remove the battery. Don't pull the wires! Hold onto the plastic battery housing.

    • After removal, inspect the battery contacts and connector on the laptop. If they are oxidized, wipe them with alcohol. Do not use abrasive materials - this will damage the coating.

    ⚠️ Attention: On some models (ASUS N550, N750) the removable battery is connected through a cable, and not through contacts. In this case Do not pull the battery up — first you need to disconnect the cable from the motherboard (you will need to disassemble the laptop).

    Removing a soldered or glued battery (ZenBook, ROG, VivoBook)

    If your laptop is a premium or gaming laptop, most likely the battery is not removable. In this case, the process is more complicated and requires patience. Let's consider a universal algorithm using an example ASUS ZenBook UX430:

    Step 1: Remove the bottom cover.

    • 🔧 Remove all screws (usually 8-12 pieces). B ROG Strix some screws may be hidden under the rubber feet.
    • 🕳️ Pry off the lid with a plastic spatula, starting from the corner. Be careful - in VivoBook the lid is often held in place by latches that are easy to break.

    Step 2: Disconnect the battery from the motherboard.

    • 🔌 Find the battery connector (usually black or white, with the inscription BAT or Battery).
    • 🖱️ Carefully pry the connector with a plastic spatula and disconnect it. Don't pull the wires!

    Step 3: Remove the battery.

    • 🔥 If the battery is glued (as in ROG Zephyrus G14), heat it with a hairdryer (temperature no higher than 60°C), then pry it off with a spatula.
    • 🔧 If the battery is secured with screws, unscrew them (usually 2-4 screws).

    On some models (ASUS TUF A15) the battery may be soldered to the board. In this case, removal will require a soldering station and experience with electronics. Do not try to unsolder the battery yourself - this is fraught with a short circuit.

    What to do if the battery is swollen?

    If the battery is swollen, it cannot be pierced or bent - this may cause a fire. Carefully remove the battery (if possible) and place it in a non-flammable container (such as a metal can). Dispose of it at special collection points (in Russia - through the Ecotekhprom system).

    Common mistakes and how to avoid them

    Even experienced users sometimes make mistakes when removing the battery. Here are the most common ones and how to prevent them:

    • ❌ Disassembly with the laptop turned on. This may lead to reset BIOS (especially in models with Intel Management Engine) or damage to the power controller. Always turn off your laptop and unplug the charger!
    • ❌ Using metal tools to pry off the lid. This leaves scratches and can short out the contacts. Use only plastic spatulas.
    • ❌ Applying force to the battery latches. B ASUS X550 and similar models, the latches are plastic and break easily. If the battery cannot be removed, check that all latches are disengaged.
    • ❌ Ignoring loops. On some models (ASUS N550) the battery is connected via a cable that needs to be disconnected to removing the battery.

    Another typical problem is loss of screws. B ROG Strix And TUF The screws are of different lengths, and if they are mixed up, you can damage the motherboard. To avoid this, arrange screws in groups or take photographs of their locations.

    1) Is the power connector connected to the motherboard correctly?

    2) Is the battery cable damaged (relevant for ZenBook).

    3) Are the BIOS settings lost (try resetting them by removing the CMOS battery for 10 seconds).-->

    What to do after removing the battery: checking and installing a new one

    After removing the battery, inspect it for damage:

    • 🔍 Bloating. If the battery case is deformed, it cannot be used - recycling only.
    • 🔌 Oxidation of contacts. Wipe them with alcohol or an eraser (carefully!).
    • 📏 Connector status. If the contacts are bent, straighten them with a thin screwdriver.

    When installing a new battery:

    1. Connect the connector to the motherboard (if it was disconnected).
    2. Secure the battery with screws or glue (if so provided by the design).
    3. Make sure that the cables are not pinched or touch moving parts (for example, a cooler).
    4. Reassemble the laptop in reverse order.

    After assembly:

    • 🔋 Connect the charger and turn on the laptop. If it does not respond, check the connection of the battery and connectors.
    • 🖥️ Go to BIOS and reset settings to default (Load Default Settings).
    • 📊 Install a battery calibration program (for example, ASUS Battery Health Charging or MyASUS).
    ⚠️ Attention: In laptops ASUS ROG with two batteries (eg Zephyrus Duo) you can't connect just one - this can lead to uneven load and failure of the power controller. Always install both batteries or none (operate on mains power only).

    FAQ: Frequently asked questions about removing the battery from an ASUS laptop

    Is it possible to remove the battery on a running laptop?

    No, this is extremely dangerous. On most laptops ASUS (especially with processors Intel 8th generation and later) Hot removal of the battery may result in:

    • Resetting the BIOS and losing settings (including boot priority).
    • Damage to the power controller (especially in models with NVIDIA Optimus).
    • Loss of data on NVMe drives (due to sudden power failure).

    The exception is laptops with the option Hot-swap Battery in BIOS (rarely found in business series ASUSPRO).

    How to remove the battery if the screws cannot be removed?

    If the screws are stuck or have a non-standard head:

    • Use screwdriver with magnetic tip (For example, iFixit Mako).
    • If the screw breaks, drip WD-40 or alcohol and wait 5-10 minutes.
    • As a last resort, carefully drill out the screw with a drill (only if you plan to replace the cover).

    In laptops ASUS ROG sometimes there are screws with single-sided thread (for example, in Strix Scar). They need to be unscrewed counterclockwise, but with effort - they can “bite”.

    What should I do if the laptop does not turn on after removing the battery?

    The problem could be the following:

    1. Battery connector not connected. Check if the plug is firmly seated on the motherboard.
    2. Broken BIOS settings. Remove the CMOS (coin type) battery for 10 seconds, then reinsert it.
    3. Damaged power controller. If the laptop does not respond even to charging, contact service.
    4. Protection against non-original battery. On some models (ZenBook) the laptop blocks work with unofficial batteries. Try updating your BIOS.
    Is it possible to fly on an airplane with the battery removed?

    Yes, but there are nuances:

    • 🛫 In hand luggage: Removed battery you can transport, but it must be individually packaged (for example, in the original box or wrapped with tape).
    • ✈️ In luggage: Lithium batteries prohibited checked in as baggage (according to IATA rules).
    • 📄 Documents: Battery capacity >100 Wh may require airline approval.

    A laptop without a battery can be transported in any form (but do not forget about the rules for transporting electronics).

    How can I check if the battery in my ASUS is original?

    Original batteries ASUS have:

    • 🏷️ Sticker with serial number, which can be checked on the website ASUS support.
    • 🔋 ASUS logo on the body (sometimes with a hologram).
    • 📊 Capacity matching (check in MyASUS → Battery Health). Non-original batteries often have a low capacity.

    Also original batteries support the function Battery Health Charging (limit charge to 60–80% to extend service life).
