Over time, the laptop begins to work slower, gets hotter, or simply stops coping with modern tasks. Instead of buying new equipment, you can improve your current laptop - it is often cheaper and more effective. In this article, we will look at which components can be upgraded, and where it is better not to take risks, so as not to turn the laptop into a “brick”.

Not all laptops are equally repairable: ultrabooks Apple MacBook or Dell XPS often have soldered components, whereas gaming models ASUS ROG or MSI allow you to replace almost everything. Before using a screwdriver, check service manual your model - it can be found on the manufacturer’s website or on iFixit. If you've never disassembled your equipment, start with simple improvements: cleaning the system or replacing thermal paste.

There are no universal tips in this article - only specific recommendations taking into account the type of laptop (office, gaming, ultrabook) and budget. For example, Replacing an HDD with an SSD gives a performance increase of up to 500%, even if other components remain the same. And in some cases, it is enough to configure Windows correctly for the laptop to “fly”.

1. Replacing the hard drive (HDD) with SSD

The simplest and most effective upgrade for any laptop over 5 years old. Traditional HDD (hard drives) with mechanical parts lose SSD tens of times faster. After replacement, the system will boot in 10–15 seconds, and programs will open instantly. Even budget SATA SSD (For example, Crucial MX500 or Samsung 870 EVO) is superior to any HDD.

For laptops with interface M.2 NVMe (most models after 2017) faster drives such as WD Black SN850X or Samsung 990 Pro. They are more expensive, but they justify themselves in games and video work. Before purchasing, check which type of SSD your laptop supports:

  • 🔧 SATA III — maximum speed ~550 MB/s (suitable for office tasks).
  • ⚡ NVMe PCIe 3.0 - up to 3500 MB/s (ideal for gaming and editing).
  • 🚀 NVMe PCIe 4.0/5.0 — from 5000 MB/s (needed for professional workloads).

How to transfer data from an old disk? Use cloning programs, e.g. Macrium Reflect or Clonezilla. If the SSD is smaller in volume than the HDD, first clear the disk of unnecessary files or transfer only the system partition.

📊 What type of drive do you have now?
  • HDD only
  • SSD SATA
  • NVMe PCIe 3.0
  • NVMe PCIe 4.0/5.0
  • I don't know
⚠️ Attention: In laptops with two slots (for example, Lenovo Legion or HP Omen) you can install an SSD along with a HDD. But if there is only one slot, you will have to sacrifice capacity or use an external drive to store files.

2. Increase random access memory (RAM)

Lack of RAM is a common cause of slowdowns, especially if you work with Photoshop, Chrome (with a dozen tabs) or modern games. The minimum comfortable volume today is 16 GB. For office tasks, 8 GB is enough, but if you edit video or stream, it’s better 32 GB.

Before purchasing please check:

  • 🔍 Memory type: DDR4 (most laptops after 2016) or DDR5 (new models, e.g. ASUS Zephyrus G14 2023).
  • 🖥️ Number of slots: one slot means you have to change the bar completely, two means you can add a module.
  • ⚡ Frequency: must match the supported motherboard (for example, DDR4-3200).
RAM capacity For what tasks is it enough? Approximate prices (2026)
8 GB Office, web surfing, old games 2 000–3 500 ₽
16 GB Modern games, 1080p video editing, programming 4 000–7 000 ₽
32 GB 4K editing, streaming, virtual machines 8 000–12 000 ₽
64 GB Professional work with 3D, rendering, server tasks 15 000–25 000 ₽

If the laptop already has one stick (for example, 8 GB), it is better to buy a second one with the same characteristics so that it will turn on dual channel mode - this will speed up work by 10–20%. To check compatibility, use utilities like CPU-Z or HWiNFO.

💡

Before installing new memory, update your laptop's BIOS - this will help avoid compatibility issues, especially if you are using high-frequency modules.

3. Replacing thermal paste and cleaning from dust

Over time, the thermal paste dries out and the cooling system becomes clogged with dust. This leads to overheating, throttling (automatic performance reduction) and even sudden shutdowns. Replacing thermal paste and cleaning the fan can reduce the temperature by 10–20°C, which is especially important for gaming laptops.

Which thermal paste should I choose?

  • 💰 Budget: Arctic MX-6 or DeepCool Z5 - enough for 2-3 years.
  • 🔥 Middle segment: Noctua NT-H2 or Thermal Grizzly Kryonaut — the best price/quality balance.
  • 🏆 Premium: Thermal Grizzly Conductonaut (liquid metal) - for extreme cooling, but requires caution (conducts electricity!).

How to clean your laptop from dust:

Turn off the laptop and remove the battery (if removable)

Unscrew the bottom cover (use a plastic clip spatula)

Blow out the fan and radiator with compressed air (can or compressor)

Remove old thermal paste with alcohol and cotton swabs

Apply a thin layer of new paste (about the size of a pea)

Reassemble the laptop and check the temperatures in HWMonitor-->

If the temperature is still high after cleaning, the problem may be degraded thermal pad between the chip and the heatsink. In this case, it also needs to be replaced (for example, with Fujipoly Ultra Extrem).

⚠️ Attention: In laptops with soldered memory (for example, Apple M1/M2 or some Lenovo Yoga) Replacing thermal paste yourself may void the warranty. In such cases, it is better to contact the service.

4. Processor upgrade (CPU)

Replacing a processor is one of the most difficult upgrades, but in some cases it is worth it. For example, if you have a laptop with removable CPU (most models until 2020 are on the platform Intel or AMD) and you want to significantly increase performance.

Things to consider:

  • 🔧 Socket: must match the motherboard (eg LGA 1151 for Intel 8th/9th generation or FP6 for AMD Ryzen 4000/5000).
  • 🖥️ TDPNote: The new processor must not exceed the maximum power consumption that the cooling system is designed to handle.
  • ⚡ BIOSNote: Some laptops require a firmware update to support new CPUs.

Examples of successful upgrades:

  • 📈 Intel Core i5-8300H → i7-8750H (up to 30% increase in games and rendering).
  • 🚀 AMD Ryzen 5 3550H → Ryzen 7 4800H (improved multi-threaded performance by 2 times).

Where to buy a laptop processor? On AliExpress or eBay They often sell used chips in good condition. But be careful: some sellers give out rebranding processors (eg i7-9750H with reduced frequencies) for full-fledged models.

How to check processor compatibility?

1. Find out your motherboard model (via CPU-Z or a sticker under the lid).

2. Find the board specifications on the manufacturer's website (section "Supported CPUs").

3. Check the list with the desired processor.

4. Check reviews on forums (eg. NotebookReview or Reddit) - sometimes newer chips are unofficially supported.

5. Replacing the video card (only for some models)

90% of laptops have a video card soldered in into the motherboard and cannot be replaced. However there are exceptions:

  • 🎮 Laptops with MXM slot (for example, old Alienware or Clevo).
  • 🔧 Some models Dell Precision or HP ZBook with removable GPUs.
  • 🖥️ External video cards via Thunderbolt 3/4 (For example, eGPU Razer Core).

If your laptop supports GPU replacement, please note:

  • 🔌 Maximum power: for example, slot MXM 3.0 Type B Supports cards up to 120W.
  • 🖼️ Driver compatibility: Some laptops block non-original video cards.
  • 💰 Price: used NVIDIA RTX 2070 Mobile will cost 15,000–20,000 ₽, and RTX 3080 Mobile — from 50,000 ₽.

For most users external video card - a more realistic option. For example, boxing ASUS ROG XG Mobile with RTX 4090 turns even a weak ultrabook into a gaming station. But there are nuances:

  • ⚡ Performance losses of up to 15–20% due to the interface Thunderbolt.
  • 💻 Requires a laptop with a supported port (usually USB-C/Thunderbolt 3/4).
  • 💰 The cost of the set (box + video card) starts from 80,000 ₽.

6. Screen upgrade

If your laptop's display is dim, has poor viewing angles, or low resolution, you can replace it. This is true for older models (before 2018), where there were often TN panels with permission 1366×768. Modern IPS or OLED-screens offer:

  • 🌈 Wider color gamut (100% sRGB vs 60–70% for older matrices).
  • 🔍 High resolution: Full HD (1920×1080) or 4K (3840×2160).
  • ⚡High refresh rate: 120 Hz or 144 Hz for games.

How to choose a new matrix:

  1. Find out the exact screen model (via AIDA64 or a sticker on the back of the matrix).
  2. Find a replacement with the same connector (For example, eDP 30-pin) and size (13.3", 15.6", etc.).
  3. Check compatibility with the backlight inverter (if available).

Examples of successful upgrades:

  • 📺 Replacement 1366×768 TN on 1920×1080 IPS in Lenovo ThinkPad T440p - the difference is like between day and night.
  • 🎨 Installation OLED 4K in Dell XPS 15 for working with graphics.
⚠️ Attention: In laptops with touchscreen Replacing the matrix often requires transferring the sensor layer, which complicates the process. Also some models (for example, MacBook Pro) have proprietary connectors, and it is extremely difficult to find a replacement.

7. Battery replacement

A laptop battery degrades over time: after 2–3 years, the capacity drops by 30–50%, and battery life is reduced to 1–2 hours. Replacing the battery can return autonomy to the level of new technology.

How to choose a new battery:

  • 🔋 Original: expensive (RUB 5,000–RUB 15,000), but guaranteed to be compatible and safe.
  • 💰 Analogue: cheaper (2,000–6,000 RUR), but there is a risk of running into poor-quality assembly.
  • 🔌 External battery (For example, Anker PowerCore) - if the original battery is non-removable.

Before purchasing please check:

  • 📏 The exact name of the battery model (written on the old one).
  • 🔧 Compatible with power controller (some non-original batteries are not detected by the system).
  • 🔋 Capacity: must match or be higher than the original one (for example, 48 Wh → 65 Wh).

After replacing the battery calibrate it: Discharge completely and then charge to 100% 2-3 times. This will help the controller correctly determine the capacity.

💡

If the laptop does not turn on on battery power, but works on mains power, the problem may not be with the battery, but with the power controller on the motherboard. In this case, diagnostics in the service is required.

8. Software optimization: what can be done without an upgrade

You don't always have to take your laptop apart to improve its performance. Often enough correct settings:

  • 🖥️ System cleaning: Uninstall unnecessary programs via Control Panel → Programs and Features.
  • 🔄 Disabling startup: in Task Manager (Startup tab) disable everything except the antivirus.
  • 🛡️ Reinstalling Windows: A clean system without “garbage” works 20–30% faster.
  • 🔧 Driver Update: especially important for the video card and chipset (download from the manufacturer’s website, not through Windows Update).
  • ⚡ Performance Mode: in Control Panel → Power Options Select the "High Performance" scheme.

Useful for gaming laptops:

  • 🎮 Undervolting (CPU voltage reduction) via ThrottleStop - Reduces temperature and increases productivity.
  • 🖼️ Graphics optimization: in NVIDIA Control Panel Set "Preferred Graphics Device" to your discrete graphics card.

If the laptop slows down due to low memory, but RAM upgrade is not possible, use swap file on an SSD or external drive with technology ReadyBoost (on Windows). This will not replace RAM, but it will help with simple tasks.

FAQ: Frequently asked questions about laptop upgrades

Is it possible to replace the processor in an Apple MacBook laptop?

In the majority MacBook (since 2016) processor soldered in into the motherboard, so it cannot be replaced. Exception - some models MacBook Pro until 2015 (for example, with processors Intel Core i7-4xxx), but even there the upgrade is limited to compatible chips.

Is it worth buying an external video card for a laptop?

External video card (eGPU) is justified if:

  • Do you have a laptop with Thunderbolt 3/4 (For example, MacBook Pro or Dell XPS).
  • You do rendering, video editing, or play less demanding games.
  • You are willing to accept productivity losses (10–20% due to the interface).

For modern games at maximum settings eGPU If it doesn’t work, it’s better to build a full-fledged PC.

How to check which SSD my laptop supports?

Methods:

  1. Use the utility HWiNFO - it will show the connection type (SATA or NVMe) and free slots.
  2. Look at the model specifications on the manufacturer's website (section "Storage").
  3. Disassemble the laptop and check the stickers on the slots (for example, M.2 2280 PCIe x4).
What to do if, after replacing the SSD, the laptop does not see the disk?

Possible causes and solutions:

  • 🔌 The disk is not initialized: go to Disk management (Win + X), find a new SSD and create a volume on it.
  • 🖥️ Wrong format: Format the disk to NTFS.
  • ⚡ Problems with SATA/NVMe: Check if your laptop supports the connection type (for example, some older models do not work with NVMe).
  • 🔧 BIOS doesn't see the drive: Update the motherboard firmware.
Is it possible to improve the sound on a laptop?

Upgrading the built-in speakers is almost impossible, but you can improve the sound using software:

  • 🎵 Use Equalizer APO to adjust the equalizer.
  • 🔊 Connect external speakers or headphones via USB-C or Bluetooth 5.0 (For example, JBL Charge 5).
  • 🎧 To record your voice, use an external microphone (for example, Fifine K669B).

Some laptops (eg. ASUS ROG) you can replace the sound card with a better one, but this is rare.
