Your old laptop ASUS slows down, gets hot and can barely cope with modern tasks? Don't rush to send it to the landfill! Even models from 5-7 years ago (for example, ASUS X550VX, K551LN or F555LA) can be brought back to life with minimal investment. In this article - 7 proven methods, how to upgrade a laptop without buying a new one: from replacing thermal paste to upgrading the SSD and fine-tuning Windows.

We'll sort it out hardware and software methods, which work on 90% of models ASUS (series ZenBook, VivoBook, ROG, Transbook and budget lines). We will pay special attention critical upgrade errors that can kill the laptop forever - for example, why you can’t put an SSD in a DVD drive slot without an adapter, or how improperly cleaning the cooler leads to overheating of the processor.

1. Diagnostics: determine the weak point of the laptop

Before spending money on an upgrade, find the bottleneck your ASUS. Brakes can be caused by:

  • 🐢 Slow HDD — if the laptop “thinks” when opening folders or launching programs.
  • 🔥 Overheating - sudden shutdowns, fan buzzing, hot case.
  • 🧠 Lack of RAM — freezes when working with the browser (10+ tabs) or editors.
  • 🖥️ Outdated OS — Windows 10/11 on weak hardware without optimization.

For accurate diagnostics, use free utilities:

  • 📊 CrystalDiskInfo — checking the HDD/SSD status (see parameter Reallocated Sectors Count).
  • 🌡️ HWMonitor — temperature monitoring (norm for processor: up to 85°C under load).
  • 🖥️ Task Manager — CPU/RAM load (if RAM is 90% full, an upgrade is needed).
📊 What ASUS laptop do you have?
  • ZenBook
  • VivoBook
  • ROG
  • Transbook
  • X-series (X550, X555, etc.)
  • Other

⚠️ Attention: If in HWMonitor CPU temperature exceeds 95°C, turn off your laptop immediately - this is a risk of chip damage. First solve the cooling problem (cleaning + replacing thermal paste), and only then upgrade.

2. Hardware upgrade: what can be replaced in an ASUS laptop

Most laptops ASUS (except ultrabooks ZenBook UX) allow you to upgrade:

Component Maximum upgrade Difficulty of replacement Approximate cost (2026)
RAM Up to 16–32 GB (depending on model) ⭐⭐ (easy) 2 000–6 000 ₽
HDD → SSD SATA III (up to 1 TB) or NVMe (up to 2 TB) ⭐⭐⭐ (average) 3 000–10 000 ₽
Battery Original or analogue ⭐⭐ (easy) 1 500–4 000 ₽
Thermal paste High temperature (eg Arctic MX-6) ⭐⭐⭐⭐ (difficult) 300–800 ₽
Wi-Fi module Dual band (5 GHz) ⭐⭐⭐ (average) 800–2 500 ₽

⚠️ Attention: In laptops ASUS ROG (For example, GL552VW) is often used soldered memory - it cannot be replaced! Check your model's specifications on the website ASUS support (section Specifications → Memory).

Back up data to an external drive

Buy an antistatic wrist strap (or work on a wooden surface)

Prepare screwdrivers (phillips, flat, sometimes needed T5)

Download drivers for new hardware (especially for SSD NVMe)

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

-->

3. Replacing HDD with SSD: major performance boost

Transition from HDD to SSD - the most noticeable upgrade for an old laptop. Windows boot speed will increase by 3–5 times, and programs will open instantly. For most models ASUS suitable:

  • 💾 SATA III SSD (For example, Crucial MX500, Samsung 870 EVO) - for laptops until 2018.
  • ⚡ NVMe SSD (For example, WD Black SN770, Samsung 980 Pro) - if there is a connector M.2 2280 (check via HWiNFO).

🔧 Step by step instructions:

  1. Clone your system from HDD to SSD using Macrium Reflect or Clonezilla.
  2. Open the back cover of the laptop (on some models ASUS To do this you need to remove the keyboard!).
  3. Remove the old HDD and install the SSD in the same slot (for M.2 use a standard screw).
  4. If you want to leave the HDD as a second drive, buy DVD drive bay adapter (For example, ORICO 2.5" to 9.5mm).
💡

After replacing the SSD, be sure to check the operating mode in Disk Management (Win + X → Disk Management). If the drive appears as GPT, but works in mode Legacy BIOS, switch to UEFI for maximum speed.

⚠️ Attention: In laptops ASUS Transbook (For example, T100) is often used eMMC memory, which cannot be replaced. In this case, only Windows optimization will help (see section 5).

4. Cleaning and replacing thermal paste: combating overheating

Over time, the thermal paste dries out and dust clogs the radiator - this leads to throttling (automatic reduction of processor frequency) and sudden shutdowns. Cleaning is recommended once every 1–2 years.

🛠️ What you will need:

  • 🧴 Thermal paste (Arctic MX-6, Noctua NT-H2).
  • 🧹 Brush (soft, for dust).
  • 🪛 Screwdrivers (PH00, T5 - depends on the model).
  • 🧻 Lint-free wipes and isopropyl alcohol (90%+).

🔧 How to clean:

  1. Turn off the laptop, remove the battery (if removable) and the back cover.
  2. Carefully remove the cooling system (unscrew the screws diagonally so as not to bend the radiator!).
  3. Remove old thermal paste from the processor and video card chip (if any) with alcohol and a tissue.
  4. Apply new paste thin layer (about the size of a grain of rice) and spread evenly.
  5. Blow out the radiator with compressed air (or a clean brush) and put everything back together.
What happens if you apply too much thermal paste?

Excess paste may leak onto motherboard components, cause a short circuit, or impair heat dissipation. The optimal layer is 0.5–1 mm (for laptops).

⚠️ Attention: In laptops ASUS ROG (For example, GL502VM) is often used liquid metal instead of thermal paste. It cannot be replaced with regular paste - this will lead to overheating! In this case, you need a specialized paste (for example, Coollaboratory Liquid Ultra).

5. Windows optimization: software overclocking

Even after a hardware upgrade unoptimized Windows may slow down. Here's what to do:

🔄 Disable unnecessary services:

  • 🖥️ Go to Start → Run → services.msc.
  • 🛑 Disable:
    • Superfetch (SysMain) — caches data, but only slows down on the HDD.
    • Windows Search - if you do not use file search.
    • DiagTrack - Microsoft telemetry.

⚡ Power settings:

  • Go to Control Panel → Power Options.
  • Select a scheme High performance (even on battery).
  • B Additional options install:
    • Minimum processor state → 100%.
    • Battery threshold → 80% (will extend battery life).
💡

The most effective way to speed up Windows on a weak laptop is to turn off visual effects. Go to Control Panel → System → Advanced system settings → Performance and select Provide better performance.

🧹 System cleaning:

  • 🗑️ Remove junk using CCleaner or BleachBit.
  • 📦 Uninstall unnecessary programs via Control Panel → Programs and Features.
  • 🔍 Check startup: Ctrl + Shift + Esc → Startup (disable everything except antivirus).

6. Alternative OS: what to install instead of Windows

If your laptop is too weak for Windows 10/11, consider lightweight alternatives:

Operating system Minimum Requirements Pros Cons
Linux Mint (Xfce) 1 GB RAM, 15 GB disk Fast, stable, driver support Not all Windows programs work
ChromeOS Flex 2 GB RAM, 16 GB disk Simple, cloud-based, good performance Limited functionality (browser + Android apps only)
Windows 10 LTSC 2 GB RAM, 20 GB disk No unnecessary updates, easy No Microsoft Store, hard to find image
AntiX Linux 512 MB RAM, 5 GB disk The lightest, works even on Pentium 4 Complex interface for beginners

🔧 How to install:

  1. Download the image from the official website (for example, Linux Mint).
  2. Write to a flash drive using Rufus (select partition scheme MBR for old laptops).
  3. Boot from the flash drive (click F2, Del or Esc when turning on to enter the BIOS and select the boot device).
  4. Install the system next to Windows (or instead of it).

⚠️ Attention: On laptops ASUS with Secure Boot (For example, ZenBook UX330) Linux may not start. In this case, disable Secure Boot in BIOS (Boot → Secure Boot → Disabled).

7. External accessories: how to expand your capabilities

If hardware upgrade is not possible, external devices will help compensate for the weaknesses of the laptop:

  • 🖥️ External monitor - connect via HDMI or USB-C (For example, ASUS ProArt PA248QV). This will relieve the built-in graphics.
  • 💾 External SSD - for example, Samsung T7 Shield (1 TB, USB 3.2). Use as a system drive or to store files.
  • 🎮 External video card - through Thunderbolt 3 (For example, ASUS ROG XG Station). Suitable for ASUS ROG and some ZenBook.
  • ⌨️ Keyboard and mouse - wireless (for example, Logitech MX Keys) will take the load off the touchpad and built-in keyboard.

💡 Life hack for gamers: If you have a laptop ASUS ROG (For example, GL553VD) with Thunderbolt 3, you can connect external GPU dock (For example, Razer Core X) and install a full-size video card (for example, RTX 3060 Ti). This will give an increase in games up to 200–300%!

💡

External GPU only works with laptops that have a connector Thunderbolt 3 (indicated by a ⚡ icon). Check the specifications of your model on the ASUS website!

FAQ: Frequently asked questions

Is it possible to put two SSDs in an ASUS laptop: one in the HDD slot, the other in M.2?

Yes, if the laptop has both connectors. For example, in ASUS X550VX can be installed SATA SSD instead of HDD and NVMe SSD into slot M.2. But keep in mind:

  • The BIOS may not support booting from NVMe (solved by updating the BIOS).
  • Some models (eg ASUS K551LN) have only one slot M.2, which is occupied by the Wi-Fi module.

Please check compatibility via UserBenchmark (enter laptop model).

Is it worth updating the BIOS on an old ASUS laptop?

Updating the BIOS may add support for new processors or SSDs, but risky:

  • ✅ It's worth updating if: the new version fixes critical bugs (for example, problems with NVMe).
  • ❌ Not worth it if: The laptop works stably, and the update only adds “minor improvements”.

🔧 How to update safely:

  1. Download the firmware from ASUS official website (only for your model!).
  2. Connect your laptop to a UPS (or at least a surge protector).
  3. Do not update via Wi-Fi - only via cable.
  4. Do not interrupt the process (even if the laptop is frozen at 99%).
How to check if my ASUS laptop supports NVMe SSD?

There are 3 ways:

  1. Visually: Open the back cover and see if there is a connector M.2 with key M (for NVMe). Keyed connector B or B+M only supports SATA SSD.
  2. Via HWiNFO: Launch the utility, go to Motherboard → M.2 Slots. If in line Protocol indicated PCIe x4, then NVMe is supported.
  3. By model: Check the specifications on the ASUS website (section Storage). For example, ASUS FX503VD supports NVMe, and ASUS X540SA - no.

⚠️ Attention: Even if there is a connector, the BIOS may not have an option to boot from NVMe. In this case, you will have to update the BIOS or install Windows on SATA SSD.

My ASUS laptop does not turn on after the upgrade. What to do?

Causes and solutions:

  • 🔋 Power not connected: Check that the battery and power supply are connected correctly. On some models (for example, ASUS N550JK) the laptop will not turn on without a battery, even if connected to the network.
  • 🧠 Incompatible RAM: If you installed a new RAM stick, try:
    • Install it in another slot.
    • Return the old bracket and check if the laptop turns on.
    • Update BIOS (sometimes support for new RAM modules is added).
  • 💾 SSD problems: If you replaced the disk, check:
    • Is the SSD connected correctly (sometimes you need to press it harder).
    • Reset BIOS (remove battery CR2032 for 10 minutes).
    • If SSD NVMe, but the laptop does not see it - update the BIOS.

If all else fails, reset BIOS to factory settings (press F2 or Del when turned on, then select Load Default Settings).

What is the easiest antivirus for an old ASUS laptop?

Top 3 antiviruses with minimal system load:

Antivirus RAM consumption (in background) Free version Features
Kaspersky Security Cloud Free ~150 MB Yes Good protection, but sometimes slows down when scanning.
Bitdefender Antivirus Free ~100 MB Yes Minimalistic, but there is no Russian language.
Windows Defender (built-in) ~50 MB Yes The easiest, but weak protection against 0-day threats.

💡 Advice: Disable automatic scanning in your antivirus settings and run a manual scan once a week. This will reduce the load on the processor.
