Where is the battery in a laptop: search and features in 10+ popular models

You're trying to replace the battery but can't figure it out. where is the battery located in a laptop? This problem is familiar to many - especially when it comes to modern ultrabooks with non-removable covers or models with non-obvious arrangement of elements. Unlike older devices, where the battery could be removed in a second, today manufacturers hide it under decorative panels, adhesive bases, or even inside the case.

In this article we will look at exact locations of batteries in laptops of different brands - from MacBook Air to gaming MSI, and also tell you how to safely remove them. You will learn what tools you will need, how to avoid damaging the cables, and what to do if the battery is “swollen.” For clarity, we present unique disassembly diagrams for 5 popular models from 2023–2026, which are not in the standard instructions.

Why does the battery location differ between laptops?

The battery design depends on three key factors: device form factor, its purpose and year of manufacture. For example, in budget laptops Acer Aspire or Lenovo IdeaPad The battery is often removable - it can be removed by sliding the latch on the bottom cover. And in premium Dell XPS or HP Spectre The battery is integrated into the body and glued to the aluminum frame to save space.

One more nuance - gaming laptops (For example, ASUS ROG or MSI Raider). Here the battery is often divided into two modules located on the sides of the motherboard. This is due to the need to distribute weight and keep powerful components cool. At the same time in MacBook Pro The battery is a single lithium-polymer unit, occupying up to 30% of the internal space.

• 🔋 Removable batteries: found in laptops before 2015 and some budget models (for example, Lenovo ThinkPad T480).
• 🔌 Built-in (non-removable): standard for ultrabooks (MacBook Air, HP Envy) and most devices after 2018.
• 🔧 Modular: several small batteries connected in parallel (typical for gaming laptops).

Interesting fact: in some models Microsoft Surface The battery is hidden under the keyboard, not under the bottom cover. This complicates access, but allows you to make the device thinner.

Where to look for a battery: 5 typical places

If you don't know which side to approach disassembly, start by inspecting the case. Here most common placeswhere manufacturers place batteries:

1. Under the removable cover (on the bottom panel). Typical for laptops with service hatches, for example, Lenovo Legion or Dell Inspiron. The cover can be secured with 1–2 screws or latches.
2. Under the entire bottom panel. In this case, you will have to unscrew 10–15 screws and carefully pry off the cover with a pick (this is how the MacBook Pro And HP Pavilion).
3. Under the keyboard. A rare but common option - for example, in Microsoft Surface Book or some Samsung Notebook.
4. In a “sandwich” with the motherboard. The battery may be on top or under the board (typical for Razer Blade).
5. In a separate compartment on the side. Found in transformers and 2-in-1 devices, for example, Lenovo Yoga.

Before disassembling your laptop, check to see if the battery is stuck. B MacBook and some HP use adhesive tape, which must be heated with a hairdryer or a special tool to safely separate.

Step-by-step instructions: how to find and remove the battery

If you decide to replace the battery yourself, follow this algorithm. Important: before disassembly turn off the laptop, disconnect the charger and hold down the power button for 10 secondsto discharge the capacitors.

Step 1: Removing the Bottom Cover

Most laptops have the battery hidden under the bottom panel. To remove it:

1. Turn the laptop over and remove all screws. In some models (for example, MacBook) they may be hidden under the rubber feet - carefully pry them off.
2. If the cover does not come off, check for hidden latches around the perimeter. B Dell XPS 13 they are located near the screen hinges.
3. Use a plastic card or pick to pry up the cover, starting from the corner. Do not use metal tools as they may scratch the casing.

Step 2: Battery Localization

After removing the cover, inspect the interior:

• 🔍 The battery usually looks like a rectangular block with wires leading to the motherboard.
• 🔌 In some models (HP Omen) it can be covered with a metal plate with additional screws.
• ⚠️ If the battery is swollen (visible by the bulge of the cover), don't touch it with your bare hands - use gloves.

Step 3: Disconnecting the cable

Before removing the battery be sure to disconnect it from the motherboard:

1. Find the connector (usually white or black, 4-6 pins).
2. Gently pull the plastic latch or pry off the cable with a flat-head screwdriver. Don't pull the wires!
3. In some laptops (Lenovo ThinkPad) the connector can be fixed with a screw - do not forget to unscrew it.

If the battery is glued, heat it with a hairdryer (temperature no higher than 60°C) and carefully pry it off. B MacBook For this purpose, special spatulas or thread are used.

For clarity, below is an example of the location of the battery in MacBook Pro 14" (2021):

MacBook Pro 14" (2021) battery diagram

The battery occupies the right side of the case and consists of 4 cells connected into one block. The power connector is located on the motherboard and is secured with a black latch. To extract you need:

1. Unscrew the 6 screws on the metal plate.

2. Heat the glue around the perimeter of the battery (use a hair dryer or iOpener).

3. Carefully pry off the block with a plastic spatula, starting from the top corner.

What to do if the battery is swollen

A swollen battery is not only loss of capacity, but also the risk of fire. If you notice that the bottom cover of the laptop has become bulging or there are gaps between the keys, immediately unplug the device and do not use it.

⚠️ Attention: Lithium-ion batteries may emit toxic gases or catch fire if damaged. Do not puncture a swollen battery or subject it to mechanical stress.

Proceed according to the following plan:

1. Isolate the laptop. Place it on a non-flammable surface (such as ceramic tile) away from flammable objects.
2. Do not charge the device. Even if the laptop turns on, it is dangerous to continue using it.
3. Remove the battery (if possible without risk of damage). For non-removable models, contact a service center.
4. Dispose of the battery at a special reception point. Don't throw it in regular trash!

If you are not confident in your abilities, do not disassemble the laptop yourself. Swollen batteries can burst if not handled carefully. At the service center they will be removed in a protective box.

How to check the condition of the battery without disassembling

Before you climb inside the laptop, it’s worth assessing the battery status programmatically. This will help you understand whether replacement is needed or calibration is sufficient.

Method 1: Via BIOS/UEFI

Most laptops have a section in the BIOS with battery information:

1. Reboot the laptop and go into the BIOS (usually the F2, Del or Esc).
2. Find the tab Power or Battery Information.
3. Check the settings Battery Health (health), Charge Level (charge level) and Cycle Count (number of cycles).

B Lenovo And Dell percentage of wear may be displayed (e.g. Wear Level: 20% - this means the capacity has decreased by 20%).

Method 2: Via Windows or macOS

Operating systems have built-in diagnostic tools:

• 🪟 Windows: Open Command line and enter:

  powercfg /batteryreport /output "C:\battery_report.html"

  The report will be saved in the root of the disk C:. Look for lines Design Capacity (factory capacity) and Full Charge Capacity (current).

• 🍎 macOS: Pinch Option (Alt) and click on the battery icon in the menu bar. The status will appear: Normal, Will need replacement soon or Replace now.

Method 3: Specialized programs

For detailed diagnostics, use the following utilities:

• 🔧 HWiNFO (Windows) - Shows cell voltage, current, and temperature.
• 🔋 Battery Health (macOS) - Displays cycle count and wear.
• 📊 AIDA64 — provides complete information about the battery model and its parameters.

If the program shows that the capacity has dropped below 60% of the factory capacity, it is time to change the battery. In modern laptops, lithium polymer batteries serve 300–500 cycles (2–3 years with active use).

Common mistakes when finding and replacing a battery

Even experienced users sometimes make mistakes that lead to laptop failure. Here top 5 misses and how to avoid them:

1. Using inappropriate tools. Metal screwdrivers scratch the case, and picks that are too thick break the latches. Use an electronics repair kit with plastic spatulas.
2. Neglect of antistatic agents. Discharge by touching a grounded object or wearing an antistatic wrist strap. Static electricity can damage the motherboard.
3. Pressing hard on a swollen battery. This is risky - it is better to carefully remove it without deforming the case.
4. Screws mixed up. B MacBook And Dell XPS screws of different lengths. If you screw a long screw into a place that is not intended for it, you can damage the board.
5. No data backup. When the battery is disconnected, the laptop may reset the BIOS settings or lose data (less commonly). Always make a backup before disassembling.

⚠️ Attention: In laptops Microsoft Surface The battery is connected to the screen via a flexible cable. If it is damaged, the display will need to be replaced, which costs up to 50% of the price of the device.

FAQ: Answers to frequently asked questions

Is it possible to replace the battery in a laptop yourself if it is non-removable?

Yes, but it requires experience. You will need: screwdrivers (usually T5 or PH00), plastic picks, a hair dryer for heating the glue (if the battery is glued) and an antistatic wrist strap. For models MacBook or Dell XPS We recommend watching the disassembly on YouTube specifically for your model — the arrangement of screws and cables may differ even within the same line.

How do you understand that the battery needs to be changed and not just reinstalled the drivers?

If the laptop discharges quickly, but in Device Manager no errors (yellow exclamation marks next to Batteries), the problem is more likely to be battery wear. Take the test:

1. Disconnect the charger and use the laptop until it is completely discharged.
2. See real operating hours. If it is less than half of what the manufacturer declared (for example, 1.5 hours instead of 6), the battery is worn out.
3. Check the report powercfg /batteryreport (see section above). If Full Charge Capacity less than 60% of Design Capacity, replacement is necessary.

Drivers only affect the display of the charge level, but not the actual capacity.

What to do if the laptop does not turn on after replacing the battery?

Possible causes and solutions:

• 🔌 Battery cable not connected. Check if the connector is inserted tightly.
• ⚡ The laptop does not “see” the new battery. Sometimes a BIOS reset is required (remove the CMOS battery for 10 seconds or use a jumper CLR_CMOS on the board).
• 🔋 Incompatible battery model. Make sure the new battery has the same part number (part number) as the old one.
• 💻 Problem with the power controller. If the laptop works from the network, but does not charge, the chip on the board may have burned out (diagnostics at a service center is required).

How much does it cost to replace a battery at a service center?

The cost depends on the model and type of battery:

Laptop type	Battery cost	Cost of work	Total
Budget (Acer, Lenovo IdeaPad)	1 500–3 000 ₽	500–1 000 ₽	2 000–4 000 ₽
Middle class (Dell Inspiron, HP Pavilion)	3 000–5 000 ₽	1 000–1 500 ₽	4 000–6 500 ₽
Premium (MacBook, Dell XPS, HP Spectre)	6 000–12 000 ₽	1 500–2 500 ₽	7 500–14 500 ₽
Gaming (ASUS ROG, MSI)	4 000–8 000 ₽	1 500–2 000 ₽	5 500–10 000 ₽

Prices are valid for Moscow and St. Petersburg for 2026. In the regions, the cost may be 10–20% lower.

Is it possible to use a laptop without a battery, directly from the network?

Yes, but with reservations:

• ✅ Works in most cases, if the power supply is working.
• ⚠️ Risks:
  • If there is a sudden power outage, data may be damaged (unless a UPS is used).
  • Some laptops (some Lenovo models) refuse to turn on without a battery - this is protection against power surges.
  • Long-term operation without a battery can lead to wear on the power connector (due to frequent charging connections/disconnections).
