Many users are faced with the problem of their laptop running slowly and are looking for a way to speed up the system. Often the only effective solution is to replace the old hard drive with a modern solid state storage. However, before purchasing a new device, a logical question arises: where exactly is the SSD physically located in your laptop and is it available for self-installation?
The answer to this question is not as clear-cut as it might seem at first glance. The design of modern ultrabooks and gaming laptops is radically different from each other. While some models have the drive slot in an easily accessible area, others require complete disassembly of the case to find it.
Understanding the internal architecture of your device is the first step to a successful upgrade. If you're planning to expand the memory or speed up the boot time of the operating system, you need to know exactly what form factor your laptop supports and where the corresponding connector is located on the motherboard.
Types of form factors and their location
Before looking for a physical installation location, it is important to determine the type of drive that supports your laptop. There are two main standards: classic 2.5" SATA and compact M.2. Each of them occupies its own unique space inside the case and has its own mounting requirements.
Classic hard drives and SATA SSDs have a rectangular shape and a standard size of 2.5 inches. They usually take up the most space and are mounted in a special compartment or basket. Such drives are most often found in gaming models, workstations and budget devices, where a large amount of memory is important, and not the minimum thickness of the case.
In contrast, M.2 modules are small boards that resemble sticks of RAM. They connect directly to the motherboard through a special connector and are secured with a screw. Due to their compact size, they can be located in the most unexpected places, sometimes even under the keyboard or processor cooling radiator.
- 🔹 SATA SSD - occupies a separate compartment, requires power and data cables
- 🔹 M.2 NVMe — installed directly into the slot on the board, no wires required
- 🔹 M.2 SATA - physically similar to NVMe, but uses a different data transfer protocol
⚠️ Attention! Never attempt to insert an M.2 drive into a 2.5-inch drive slot or vice versa. Physical notch will prevent incorrect connections, but brute force may damage the motherboard.
Where to look for a drive in cases of various brands
Laptop manufacturers approach the issue of internal space layout in different ways. Brands seem to have HP or Dell Often there is a separate cover on the bottom panel of the case specifically for quick access to the drive. This allows the user to replace or add an SSD without unnecessary tools or disassembly.
At the same time, manufacturers of ultrabooks such as Apple MacBook or ASUS ZenBook, strive for maximum compactness. In such devices, the M.2 slot may be located under the cooling system or even under the keyboard, which makes the search and replacement process much more difficult. In some rare cases, the memory is completely soldered onto the board and cannot be replaced.
Gaming laptops, such as series MSI GE or Lenovo Legion, usually have a spacious body with many compartments. Here you can often find two slots at once: one for the main disk and the second for expansion. Sometimes the second slot is hidden under a cover or requires only part of the top cover to be removed.

Visual inspection and search for a slot without disassembly
Before picking up a screwdriver, it is worth conducting a thorough visual inspection of the bottom of the device. Take a closer look at the seams of the body and the presence of separate hatches. The presence of screws that are a different color or size from the others often indicates where the access cover is attached. Also look for special hard drive or lightning bolt icons printed on the case.
If there is no separate hatch, you must remove the entire bottom cover. Be careful: on modern models, the mounts may be hidden under rubber feet or serial number stickers. Use a plastic card or a special pick to carefully open the latches so as not to damage the plastic case.
After removing the cover, the internal map of the device will open in front of you. Look for connectors that are clear of other components. If you see a rectangular metal bay secured with screws around the perimeter, this is most likely a place for a 2.5-inch drive. Compact M.2 slots are usually found closer to the center or edge of the motherboard.
- 🔍 Look for screws hidden under the rubber feet of the case
- 🔍 Check the bottom panel for storage access icons
- 🔍 Check for plugs on the case that can be easily removed
⚠️ Attention! Open the housing only on a clean, dry, non-electrical surface. Static electricity accumulated on the body can damage sensitive components on the motherboard.
Tools and preparation for the search
To successfully search for and subsequently install an SSD, you will need a minimum set of tools. A Phillips screwdriver with a magnetic tip is usually sufficient to avoid losing small screws inside the case. A plastic pick or card is also extremely useful for safely releasing the lid latches without scratching.
If you plan to transfer the system or data from an old drive, prepare an external SSD box or adapter cable in advance. This will allow you to connect both drives at the same time and clone data before physically installing a new drive in the slot. Without this step, you will have to reinstall the operating system from scratch.
Before starting work, do not forget to completely disconnect the laptop from the network and remove the battery if it is removable. Even if the battery is built-in, after removing the back cover, first disconnect the power cable from the motherboard. This will eliminate the risk of a short circuit if the contacts are accidentally touched with a screwdriver.
☑️ Preparing to replace the SSD
Location in specific models and ultrabooks
In thin ultrabooks, the placement of the SSD can be unexpected. Sometimes the M.2 module is located under the keyboard, which requires removing the entire top panel. In such cases, it is necessary to carefully disconnect the keyboard and touchpad cables so as not to tear them. Often there are also batteries located under the keyboard, which require special care during operation.
Some models Lenovo ThinkPad or HP EliteBook the M.2 slot can be covered with a metal plate with a processor cooling system. In this case, it is necessary to dismantle the entire cooling system, having first unscrewed all the screws in the correct order indicated on the radiator sticker, so as not to damage the thermal pads.
Some manufacturers such as Dell XPS or Razer Blade, use specific mounts where the SSD is secured not with a screw, but with a spring mechanism or latch. In such cases, it is important to carefully examine the slot design before removing the old drive so as not to break the retainer.
What to do if the slot is occupied?|If your laptop has one M.2 drive installed and the second slot is not available, you can consider using an external SSD via USB 3.1 Type-C to expand the storage. This solution is often cheaper and easier than searching for rare adapters for internal slots.-->
If you're not sure about the compatibility of your device, the best thing to do is go to the manufacturer's official website and find the specifications for your model. The maximum number of supported drives and their form factors are usually indicated there. This will save you time and money by preventing you from purchasing the wrong equipment.
- 🛠️ Carefully study the disassembly diagram for your specific model on the Internet
- 🔌 Look for cables that may interfere with access to the M.2 slot
- 💡 Check for thermal pads that may be covering the connector
