Is it possible to upgrade a laptop? The Complete Guide to Upgrading in 2026

Laptops have long ceased to be “disposable” equipment - many models can be upgraded, extending their life by 3-5 years. However, not all components need to be replaced: if MacBook Air soldered memory and processor, then in the gaming ASUS ROG Strix almost everything can be changed. In this article we will look at what details can be realistically updated?, and where the upgrade is pointless or dangerous. We will also compare the capabilities of budget and premium models, tell you about hidden pitfalls and provide a checklist for safe modernization.

According to the study iFixit, only 23% of 2023 laptops received a repairability rating higher than 7 out of 10. This means that the majority of devices are either difficult to disassemble without damage, or their components are non-standard. But even in such cases there are loopholes - for example, replacing thermal paste or installing an external GPU via Thunderbolt. The main thing is to understand limits of the possible and don’t overpay for useless “improvements.”

1. Which laptop components can be upgraded?

The list of replaceable parts depends on the model, but there are universal rules:

• 🔧 Random access memory (RAM) - the simplest upgrade. 80% of laptops have slots SO-DIMM accessible after removing the back cover. The exception is ultrabooks with soldered memory (for example, MacBook Pro on Apple M1/M2).
• 💾 Storage (SSD/HDD) - replaced in 95% of cases. Even if there is only one slot, you can install M.2 NVMe instead of SATA or add a second drive via an adapter.
• 🔋 Battery — theoretically replaceable, but often requires flashing the controller (relevant for Lenovo And Dell after 2018).
• 🌡️ Cooling system — cleaning and replacing thermal paste/gaskets gives +10–15% performance. In some models (for example, MSI GS66) you can change coolers.
• 🖥️ Screen - rare, but possible. B ThinkPad and some HP EliteBook The matrices are removable, but precise selection of connector and resolution is required.

But processor, video card and motherboard replacement is almost never possible. In 99% of laptops they are soldered to the board. The exception is older models before 2015 (for example, Dell Precision M4800) or specialized workstations like HP ZBook. Even if the chip is removable, replacing it will require flashing the BIOS and may lead to overheating due to incompatible cooling systems.

2. How to check the compatibility of components before upgrading?

Before purchasing new parts, you need to make sure that they will fit your model. Here 3 reliable ways:

1. Official documentation. On the sites Lenovo, HP And Dell there are sections Service Manuals with disassembly diagrams and lists of compatible components. For example, for ThinkPad T14 it states that RAM modules are supported DDR4-3200 up to 64 GB.
2. Selection services like Crucial System Scanner or Kingston Configurator. They scan your system and suggest compatible SSD and RAM.
3. Disassembly of similar models on YouTube or iFixit. Videos tagged "disassembly" or "upgrade" will show you which screws to remove and where the slots are located.

Pay special attention form factors:

• 🔹RAM: SO-DIMM DDR4 (most common) or DDR5 (in new gaming laptops).
• 🔹 SSD: M.2 2242/2280 (length 42 or 80 mm), SATA III or PCIe 3.0/4.0.
• 🔹 Battery: Check the voltage (usually 11.1V or 11.4V) and capacity in Wh.

What happens if you install incompatible memory?

The laptop may not turn on and display an error POST (flashing lights or beeps) or operate at a reduced frequency. In the worst case, the memory controller on the motherboard will burn out.

Component	How to check compatibility	Risks of error
RAM	Use CPU-Z (tab SPD)	The laptop will not start or will slow down
SSD	View supported protocols at BIOS (section Storage)	The disk will not be detected or will work at speed SATA instead of NVMe
Battery	Check the article number on the old battery with the new one (for example, L17M4PB2 for Lenovo Legion)	Laptop won't charge or shuts down at 100% charge
Thermal paste	Make sure that the new paste is non-conductive (e.g. Arctic MX-6)	Short circuit and failure of the motherboard

3. Step-by-step instructions: how to upgrade RAM and SSD?

These are the two most popular upgrades that you can do yourself. Let's look at the process using an example ASUS ZenBook 14 (UX425) - a typical mid-class ultrabook.

🔧 Replacement of RAM

1. Turn off the laptop, unplug the charger and ground yourself (touch the metal object).
2. Remove the 8 screws on the back cover (usually Torx T5 or Phillips #00).
3. Carefully pry the cover open with a plastic card, starting from the corner near the screen hinge.
4. Locate the RAM slots (usually under the black protective film). B ZenBook 14 one slot is soldered, the second is removable.
5. Press the latches on the sides of the module and remove it. Install the new one at an angle of 45° and press until it clicks.

💾SSD installation

B ZenBook 14 slot M.2 located under the metal screen next to the battery:

1. Remove the screw securing the old SSD.
2. Pull the disk through the plastic loop (do not handle the chips!).
3. Install the new SSD at a 30° angle and secure with a screw.
4. Reassemble the laptop in reverse order.

After replacing the SSD you will need clean installation of Windows or cloning the old disk using Macrium Reflect or Clonezilla. Don't forget that NVMe-disks are faster SATA 3–5 times, but only if the motherboard supports PCIe 3.0/4.0.

4. Battery upgrade: when is it justified?

The average laptop battery life is 3–4 years (or 500–1000 charge cycles). If your laptop holds a charge for less than an hour, it's time to think about replacing it. However, there are nuances:

• ⚡ Original batteries (for example, for MacBook or XPS 13) cost 30–50% of the price of a new laptop. It is often cheaper to buy a used model.
• 🔄 Analogues from third companies (like Green Cell) are cheaper, but may not display the charge percentage correctly or may discharge faster.
• 🛠️ Reflashing the controller required for Lenovo And HP after 2018. Without it, the laptop may not turn on with a new battery.

Check before purchasing article number of the old battery (printed on the label) and compare with a new battery. For example, for Dell Latitude 7490 battery will do CN-05W6J7-75734-5XJ-1G3F capacity 60 Wh. If the capacity of the new battery is higher (for example, 97 Wh), make sure that the laptop supports this voltage - otherwise the controller will block charging.

⚠️ Attention: In laptops HP Spectre x360 and some Acer Swift The battery is glued to the case. To replace it you will need hair dryer (heat the glue to 60°C) and plastic spatulas. Do not use metal tools - they may puncture the lithium polymer cells!

5. Cooling system upgrade: cleaning vs. replacement

Overheating is the main cause of performance degradation. If your laptop starts to slow down and make loud noises, it's time to start cooling. There are two ways:

1. Cleaning and replacing thermal paste (cost: 500–1500 ₽). Efficiency: +10–15°С.
2. Replacing coolers or radiators (cost: 2000–5000 ₽). Efficiency: +20–30°С, but not suitable for all models.

For cleaning you will need:

• 🧴 Thermal paste (Arctic MX-6, Noctua NT-H2).
• 🪛 Screwdriver set (Torx T4–T6, Phillips #00).
• 🌬️ Compressed air cylinder or vacuum cleaner with reverse draft.
• 🧻 Lint-free wipes and isopropyl alcohol (90%+).

Process (for example MSI GF63):

1. Remove the back cover and disconnect the battery (unplug the connector!).
2. Take photos of the location of coolers and radiators.
3. Remove the cooler, clean the blades with a cotton swab dipped in alcohol.
4. Remove old thermal paste from the processor and video card with a napkin.
5. Apply new paste (a pea-sized drop) and put everything back together.

Replacing coolers only makes sense in gaming laptops (for example, ASUS TUF Gaming or Legion 5). Like in ultrabooks MacBook Air or XPS 13 The coolers are non-removable or replacing them will not have a noticeable effect due to the compact case.

⚠️ Attention: In laptops with steam chamber (vapor chamber), for example Razer Blade 15, independent disassembly is fraught with depressurization of the cooling system. In such cases, it is better to contact the service.

6. Can Apple laptops be upgraded?

Laptops Apple are famous for their “non-repairability”, but there are exceptions:

Model	What can be replaced	What not to do
MacBook Air (M1/M2, 2020–2023)	Battery (officially), keyboard, touchpad	RAM, SSD, processor, screen
MacBook Pro 13" (2015–2019)	SSD (via adapter), RAM, battery, keyboard	Processor, video card
MacBook Pro 16" (2019–2021)	RAM (in models up to 2020), SSD, battery	Processor, screen (glued)

Main problem MacBook — proprietary components. For example, in MacBook Pro 2018+ non-standard is used SSD with controller Apple T2, which is not compatible with conventional NVMe-disks. To replace you will need an adapter like Sinotech M.2 NGFF (about 5000 ₽), but even with it the speed will be lower than the original one.

One more nuance - battery lock. B MacBook after 2017, the new battery must be “tied” to the motherboard via Apple Configurator. Without this the laptop will show the message "Service Recommended" and refuses to charge.

7. External upgrades: docking stations, GPU and peripherals

If internal upgrades cannot be carried out, you can improve the laptop “outside”:

• 🖥️ External GPU (eGPU) via Thunderbolt 3/4. Suitable for MacBook Pro, XPS 15 and other laptops with a port USB-C. Increase in games: +30–50% FPS (for example, RTX 3060 Ti in the case Razer Core X).
• 💻 Docking station with additional ports (HDMI, Ethernet, USB-A). Useful for ultrabooks with limited connectors (e.g. Lenovo Yoga).
• 🎮 Game controllers or mechanical keyboards via USB/Bluetooth. Reduce input lag (important for eSports).
• 🔊 External sound card (For example, Focusrite Scarlett) for streamers and musicians.

The main disadvantage of external upgrades is dependence on port capacity. For example, Thunderbolt 3 provides up to 40 Gbps, but in reality the external video card loses 15–20% of performance due to latency. Also, not all laptops support eGPU in Windows — sometimes manual configuration of drivers is required.

To connect the eGPU to MacBook you will need:

1. Housing with power supply (for example, Sonnet eGFX Breakaway Box).
2. Video card AMD (NVIDIA is not officially supported in macOS).
3. Cable Thunderbolt 3 (length no more than 0.5 m for minimal losses).
4. Setting in System Preferences → Displays.

FAQ: Frequently asked questions about upgrading laptops

❓ Is it possible to replace the processor in a laptop?

In 99% of cases - no. The processors are soldered to the motherboard. The exception is older models before 2015 (for example, Dell Precision M6800) or workstations like HP ZBook. But even if the chip is removable, replacing it will require:

• Compatible motherboard (with the same socket, e.g. PGA988 for Intel 4th generation).
• BIOS updates (otherwise the laptop will not start).
• Microcode flashing (in some cases).

Risks: overheating (the new model may not match the TDP), unstable operation or complete system failure.

❓ Is it worth changing HDD to SSD in an old laptop?

Yes, this is the most effective upgrade for laptops older than 5 years. Replacement HDD on SSD gives:

• Speed up Windows boot from 1-2 minutes to 10-15 seconds.
• Faster launch of programs (for example, Photoshop will open 3-4 times faster).
• Reduced noise and heat (SSD has no moving parts).

For laptops before 2015, choose SATA III SSD (For example, Samsung 870 EVO). In models after 2017 it is better to install NVMe (For example, WD Black SN850X) - it is 5 times faster.

❓ How to understand that your laptop needs cleaning?

Signs of a cooling system clogged with dust:

• Loud operation of coolers even when idle.
• Spontaneous shutdowns under load (thermal throttling).
• CPU temperature above 90°C in games or rendering (tested in HWMonitor or Core Temp).
• Hot case in the keyboard area (especially on the left, where the processor is usually located).

If the laptop is older than 3 years and at least one of the points matches, it’s time to clean it. In advanced cases, dust can cause short circuit on the motherboard.

❓ Is it possible to install two operating systems on a laptop?

Yes, but there are nuances:

• On one disk (separation via Disk Management on Windows or Disk Utility on macOS). The downside is that if one OS fails, another may suffer.
• On two disks (For example, SSD for Windows and HDD for Linux). The best option, but requires a second slot.
• Via external SSD (For example, Samsung T7 with USB-C). Slower, but safer.

For MacBook with chips M1/M2 officially supported only macOS. Windows installation is possible via Parallels Desktop (virtual machine) or UTM (ARM emulator).

❓ What to do if the laptop does not turn on after the upgrade?

Algorithm of actions:

1. Check the connections of all connectors (especially power and RAM).
2. Reset BIOS: Disconnect the battery and press the power button for 30 seconds.
3. If new RAM is installed, try booting with one module (rearrange them one by one).
4. For SSD: check that the drive is inserted correctly into the slot (it should click).
5. If all else fails, return the old components and check if the laptop turns on. If yes, the problem is in the new parts.

If the laptop makes beeps, decipher them using BIOS code table (for Dell, HP, Lenovo they are different).
