The question “is it possible to upgrade a laptop” is asked by owners of devices older than 3-4 years, when performance begins to “sag” under modern tasks. The answer is ambiguous: some models allow you to replace almost everything except the processor, others - only the drive, and still others are completely sealed “tight”. In this article we will look at which components can be realistically updated?, what to look for when choosing spare parts, and when an upgrade is not economically feasible.

The main problem is architectural restrictions. Manufacturers (especially Apple, Dell XPS, HP Spectre) are increasingly soldering RAM and storage devices to the motherboard, leaving the user only the opportunity to replace the battery. But even in such cases there are loopholes: for example, thermal paste update or installing an external GPU via Thunderbolt can give a performance boost. Below is a detailed guide with examples for different brands and models.

Which laptop components can be upgraded: complete list

The degree of “upgradability” depends on form factor and year of manufacture of the device. Below are the components that most often need to be replaced, from simplest to most complex:

  • 🔋 Battery - the safest upgrade. In 90% of laptops, the battery is removable (except for ultrabooks like MacBook Air or Lenovo Yoga).
  • 💾 Hard disk (HDD) or SSD — you can almost always replace it, but ultrabooks often use the format M.2 2242 (short), which is difficult to find on sale.
  • 🖥️ Random access memory (RAM) - budget and gaming laptops usually have free slots (for example, ASUS TUF or Acer Nitro).
  • 🌡️ Cooling system — replacing thermal paste, cleaning dust or installing copper radiators (relevant for MSI, Gigabyte).
  • 🎮 Video card (select models only) - rare, but in laptops with MXM slot (for example, old Alienware or Clevo) replacement is possible.
  • 📡 Wi-Fi/Bluetooth module - an often ignored upgrade, but a transition from Wi-Fi 5 on Wi-Fi 6E can speed up the Internet.

And now - something that can almost never be replaced:

  • ❌ Processor (CPU) - soldered in 99% of modern laptops (exception - old ones Intel Socket G3 or AMD FP5).
  • ❌ Integrated graphics (for example, Intel Iris Xe) is part of the processor.
  • ❌ Screen (except for replacement with a similar one) - updating the matrix to a more modern one (for example, with 60 Hz on 144 Hz) is often impossible due to connectors.

  • RAM
  • SSD/HDD
  • Battery
  • Cooling system
  • Video card
  • Nothing, everything is fine

How to Determine If Your Laptop is Upgradable

Before purchasing new components be sure to check:

  1. Manufacturer's documentation. On the sites Lenovo, HP or ASUS There are sections “Service Manual” or “Hardware Maintenance Manual” with disassembly diagrams. For example, for Lenovo ThinkPad T480 it states that modules are supported DDR4-2400 up to 64 GB.
  2. Diagnostic programs. Utilities like CPU-Z, HWiNFO or AIDA64 will show the current configuration and free slots: 
    CPU-Z → вкладка "SPD" → проверьте количество слотов RAM и их заполненность.
  3. Video showdown on YouTube. Search for your laptop model + “disassembly” or “upgrade”. For example, for Dell Inspiron 15 5000 there are videos that show how to get to M.2 slots.

Critical point: if your laptop has RAM soldered (for example, in MacBook Pro 2020+ or HP Envy x360), then its upgrade is impossible - only replacement of the entire device.

Brand/Series RAM upgrade Upgrade SSD Battery upgrade GPU upgrade
Lenovo ThinkPad (T/X/P-series) ✅ (up to 128 GB on some models) ✅ (2x M.2 + SATA) ✅ ❌
Dell XPS 13/15 (2020+) ❌ (soldered) ✅ (M.2 only) ✅ (but difficult) ❌
ASUS ROG Zephyrus (G14/G15) ✅ (1 slot free) ✅ (2x M.2) ✅ ❌
Apple MacBook Air/Pro (M1/M2) ❌ ❌ ✅ (but requires special tools) ❌
Acer Nitro 5 / Predator ✅ (2 slots) ✅ (2x M.2 + SATA) ✅ ❌ (except for old MXM models)
⚠️ Attention: In laptops with Intel 12th generation and later (For example, Core i7-12700H) is often used LPDDR5-memory soldered to the board. Check it out at CPU-Z on the “Memory” tab - if the type Soldered, upgrade is not possible.

Step-by-step instructions: how to upgrade RAM

Magnification RAM — the most noticeable upgrade for multitasking (working with Photoshop, Chrome with 50+ tabs, virtual machines). Minimum recommended volume in 2026 - 16 GB, optimal - 32 GB.

Find out the maximum supported volume (via Crucial System Scanner)

Buy compatible modules (for example, Kingston Fury Impact for laptops)

Prepare an antistatic wrist strap or work on a wooden surface

Make a backup copy of your data (in case of failure)

Disconnect the laptop from the network and remove the battery (if removable) -->

Replacement steps:

  1. Unscrew the back cover of the laptop (usually you need a Phillips screwdriver PH0 or PH1). In some models (for example, HP Pavilion) the lid is held on by latches - use a plastic spatula.
  2. Find the RAM slots - they look like long connectors with latches on the sides. If there is only one slot and the module is already installed, you will have to replace it (for example, from 8 GB to 16 GB). If there are two slots, it is better to install two identical modules to work in dual mode.
  3. Insert the new module at a 45° angle and press until the latches click. Make sure the contacts are not bent.
  4. Reassemble the laptop and check the memory in Windows (Start → Settings → System → About) or through memtest86 (to check for errors).

Tips for choosing RAM:

  • 🔹 For Intel 10-12 generations suitable DDR4-3200 (For example, Corsair Vengeance).
  • 🔹 For AMD Ryzen 5000/6000 better DDR4-3600 with low timings (CL18).
  • 🔹 In ultrabooks (for example, LG Gram) is often used LPDDR4X - it cannot be replaced by DDR4!

1) Are the modules inserted correctly (the latches should click).

2) Voltage compatibility (most laptops require 1.2V or 1.35V).

3) Update the BIOS - sometimes new memory requires firmware (relevant for ASUS And MSI).-->

Replacing an SSD: what to look for when choosing a drive

Updating storage from HDD on SSD — the most tangible upgrade: the system boots in 10 seconds, programs open instantly. But there are nuances here:

  • 🔧 Form factor:

    - 2.5" SATA - outdated, but still found in budget laptops (for example, Acer Aspire 3).

    - M.2 SATA - slow (up to 550 MB/s), but cheap.

    - M.2 NVMe - modern standard (speed from 2000 MB/s). Suitable for most laptops after 2017.

  • 📏 Module length:

    - 2242 (42 mm) - in compact ultrabooks (Lenovo IdeaPad).

    - 2280 (80 mm) - the most common (suitable for Dell XPS, HP Omen).

    Check the length of your current SSD or look in the manual!

  • ⚡ Protocol:

    - PCIe 3.0 (up to 3500 MB/s) - for laptops until 2020.

    - PCIe 4.0 (up to 7000 MB/s) - for new AMD Ryzen 6000 or Intel 12-13 generations.

Top 5 SSDs for upgrade (2026):

Model Form factor Capacity Speed (read/write) Price for 1 TB
Samsung 990 Pro M.2 2280 (PCIe 4.0) 1–2 TB 7450 / 6900 MB/s ~10 000 ₽
WD Black SN850X M.2 2280 (PCIe 4.0) 1–4 TB 7300 / 6600 MB/s ~9 500 ₽
Crucial P5 Plus M.2 2280 (PCIe 4.0) 500 GB – 2 TB 6600 / 5000 MB/s ~8 000 ₽
Kingston KC3000 M.2 2280 (PCIe 4.0) 512 GB – 2 TB 7000 / 6000 MB/s ~7 500 ₽
Intel 670p M.2 2280 (PCIe 3.0) 512 GB – 2 TB 3500 / 2700 MB/s ~6 000 ₽

How to transfer the system to a new SSD:

  1. Connect the new SSD via USB-SATA adapter or insert into the second slot (if available).
  2. Use Macrium Reflect or Clonezilla to clone a disk. B Macrium select the source disk → “Clone this disk” → specify the target SSD.
  3. After cloning, replace the old SSD with the new one and boot. If Windows does not start, repair the bootloader via bootrec /fixmbr on the command line.
⚠️ Attention: In laptops with Optane Memory (for example some Intel NUC or HP EliteBook) when replacing the SSD you may need to disable Optane in BIOS (Storage Configuration → Intel Optane → Disabled).

Cooling system upgrade: when you really need it

Overheating is a common problem in gaming laptops (MSI GF63, ASUS TUF Dash) and thin ultrabooks. If the processor temperature under load exceeds 90°C, and the fans are running at maximum, it's time to act. Improvement options:

  • 🧴 Replacing thermal paste - the most effective measure. The best pastes for laptops:

    - Thermal Grizzly Kryonaut (for extreme cooling).

    - Noctua NT-H2 (good price/quality balance).

    - Arctic MX-6 (does not conduct current, safe for beginners).

  • 🌀 Dust cleaning - accumulates in radiators and fans. Use a can of compressed air or a soft brush.
  • 🔧 Replacing thermal pads - if they dry out (become brittle). For GPUs, thick gaskets are often used 1.0–1.5 mm.
  • 💨 Installing a cooler with copper pipes - relevant for laptops with weak standard cooling (for example, Lenovo Legion 5 until 2021).

Step-by-step process for replacing thermal paste:

  1. Remove the back cover and get to the cooling system (you may need to disconnect the fan cables).
  2. Carefully remove the old paste with a cloth soaked in isopropyl alcohol (90%+). Don't use cotton swabs - they leave lint!
  3. Apply a thin layer of new paste (the size of a grain of rice for the CPU, a little larger for the GPU). Excess paste impairs heat dissipation.
  4. Reassemble the laptop and check the temperatures in HWMonitor or ThrottleStop under load (for example, in the test Cinebench R23).
What happens if you apply too much thermal paste?

Excess paste can leak onto the motherboard components, causing a short circuit. This is especially dangerous for laptops with a dense layout (for example, MacBook Pro or Razer Blade). Also, a thick layer impairs thermal conductivity - the temperature may even increase!

When cooling doesn't help:

  • If laptop throttlit (reduces frequencies due to overheating) even after cleaning, the problem may be degraded battery (it heats up and loads the system).
  • In ultrabooks with passive cooling (For example, MacBook Air M1) you can only replace the thermal paste, but the effect will be minimal.

Battery upgrade: how to extend the life of a laptop

The battery is the most consumable component. After 2-3 years, the capacity drops by 30-50%, and the laptop works from the outlet for 10 minutes. Signs that it's time to change the battery:

  • 🔋 The laptop turns off when the charger is disconnected, even if it shows 20-30% charge.
  • ⚡ Battery life has been reduced to 1-2 hours (from the original 6-8).
  • 🔥 The battery is swollen (can be seen from the deformation of the case). In this case, you cannot pull - a swollen battery can damage the motherboard!

How to choose a replacement:

  1. Check the battery model - it is indicated on the sticker (for example, LI20V4PC-4 for Lenovo or PA-5178-1BR2 for HP).
  2. Buy an original battery or a certified replacement (for example, from Green Cell or Camelion). Avoid cheap Chinese copies - they may not hold the container or swell after a month.
  3. For laptops with a non-removable battery (e.g. MacBook Pro) you will need special glue (B-7000) and plastic spatulas for neat removal.

How to reset the battery controller (if the laptop does not recognize the new battery):

  1. Unplug the laptop and remove the battery.
  2. Press and hold the power button on 30–60 seconds (discharges residual charge).
  3. Connect the charger without battery and turn on the laptop.
  4. Turn it off, insert the battery and turn it on again. In some models (for example, Dell Latitude) may require a BIOS reset (Load Default Settings).

1) Is the battery cable connected correctly (in some models it is fragile).

2) Controller compatibility (for example, battery from Lenovo T480 not suitable for T480s).

3) Update BIOS - sometimes firmware is required to support new batteries.-->

Exotic upgrades: what else can be improved

In addition to standard upgrades, there are less obvious ways to upgrade your laptop:

  • 📶 Replacing the Wi-Fi module. For example, in Dell XPS 15 can be installed Intel AX210 instead of the regular one Killer AX1650 - this will give support Wi-Fi 6E and lower pings in games.
  • 🎧 Sound improvement. Some laptops (eg. ASUS ROG) you can replace the speakers with better ones (for example, from Bang & Olufsen).
  • 🖥️ External GPU (eGPU). Via Thunderbolt 3/4 you can connect a full-size video card (for example, RTX 3060 Ti) in a box like Razer Core X. The increase in games is up to 2-3 times, but there are nuances:

    - Delay by Thunderbolt (~10-15%) reduces FPS in shooters.

    - The laptop must support external GPU (checked in Thunderbolt Control Center).

  • 🔦 Keyboard backlight. In some models (for example, MSI GS66) you can replace the LEDs with RGB or white ones with a different temperature.

Example of eGPU configuration for operation:

  • Boxing: ASUS ROG XG Mobile (for laptops with a proprietary connector) or Sonnet Breakaway Box (universal).
  • Video card: RTX 4070 Ti (for rendering) or RX 6700 XT (best price/performance ratio).
  • Power supply: no less 650W (For example, Corsair SF750).
⚠️ Attention: Connecting eGPU to laptops with Intel U-series (For example, Core i5-1135G7) is often limited by capacity Thunderbolt. In this case, the increase in games will be minimal (10-20%), but noticeable in rendering or machine learning.

FAQ: answers to frequently asked questions about laptop upgrades

Is it possible to upgrade the processor in a laptop?

In 99% of modern laptops, the processor is soldered to the motherboard, so it cannot be replaced. Exceptions - older models (before 2015) with sockets PGA988 (Intel) or FP5 (AMD), but even there the upgrade is limited by chipset and BIOS compatibility. For example, in Lenovo G50-70 could be replaced Core i3-4000M on i7-4700MQ, but that's history.

Is it worth upgrading your laptop or is it better to buy a new one?

An upgrade is justified if:

- The laptop is expensive (for example, MacBook Pro or Dell Precision), and replacing SSD/RAM will cost less than 20% of its cost.

- You are missing exactly one component (for example, 8 GB of RAM to work in AutoCAD).

- The laptop is less than 5 years old, and its performance is sufficient for your tasks (except for games).

It's worth buying a new one if:

- The laptop is more than 5-6 years old, and it cannot cope with modern tasks (for example, Photoshop 2026 or Cyberpunk 2077).

- Requires replacement of CPU/GPU, which are soldered.

- Repairs will cost more than 50% of the price of a new device with similar characteristics.

How to transfer Windows to a new SSD without losing data?

Use the program Macrium Reflect Free:

  1. Connect the new SSD via USB adapter.
  2. B Macrium select the system disk → “Clone this disk” → specify the target SSD.
  3. After cloning, replace the old disk with a new one.
  4. If Windows won't boot, restore the bootloader via the command line: 
    bootrec /fixmbr

    bootrec /fixboot
    

    bootrec /scanos
    

    bootrec /rebuildbcd

Alternative - Clonezilla (free, but more difficult to use).

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

Check the following:

  • 🔌 Are all cables and connectors connected correctly (especially the motherboard power supply).
  • 🔋 Battery - try turning on the laptop without it (only from charging).
  • 🖥️ RAM compatibility - if you set the wrong frequency or volume, the laptop may not start. Check the list of supported modules on the manufacturer's website.
  • 🔧 Reset BIOS - remove the CMOS battery (the small circular battery on the motherboard) for 10 minutes or find the jumper CLR_CMOS.

If all else fails, the motherboard is probably damaged (for example, when replacing the SSD, the contacts may have been bent M.2 slots).

Is it possible to put an SSD and HDD in a laptop at the same time?

Yes, if the laptop has:

- M.2 slot (for SSD) + 2.5" bay (for
