Laptop upgrade in 2026: what can be replaced and what cannot

Has your laptop started to slow down, get hot, or is it simply outdated? Don't rush to buy a new one - modern laptops can often be upgraded, saving up to 70% of the cost of a new device. However not all components can be replaced: Unlike desktop PCs, laptops have strict upgrade restrictions. In this article we will look at what can really be updated in your model, and where it is better to accept the factory equipment.

The main directions of upgrade are random access memory (RAM), storage (HDD/SSD), battery, cooling system and less often - processor or video card. But even here there are pitfalls: for example, in ultrabooks Apple MacBook or Microsoft Surface soldered memory makes upgrading impossible, and in gaming laptops MSI or ASUS ROG sometimes you can even replace the GPU. We have collected current data on models 2020–2026 and will tell you how to avoid mistakes during disassembly.

1. Diagnostics: what exactly is slowing down your laptop?

Before spending money on an upgrade, determine the bottleneck of the system. You can do this for free using built-in tools or third-party utilities:

• 🔍 Windows Task Manager (Ctrl+Shift+Esc): in the “Performance” tab, see the loading CPU, RAM And disk. If during simple tasks (for example, working in a browser) the RAM is loaded at 90%, it’s time to add more slots.
• 📊 HWiNFO or AIDA64: Shows component temperatures, hard drive and motherboard models, and supported memory types.
• 💾 CrystalDiskMark: Tests the disk read/write speed. If your HDD produces less than 100 MB/s - replacement with SSD will give a productivity increase of up to 500%.
• 🎮 3DMark or Unigine Heaven: Check the performance of the video card. In laptops it is usually integrated or discrete, but it can be replaced only in 10% of models (for example, in Alienware or Clevo with MXM slots).

Please note temperature under load: if the processor heats up above 90°C, the problem may be in the thermal paste or cooling system, and not in the hardware. In this case, the upgrade will not help - repair is needed.

2. Replacing random access memory (RAM): how much do you need and how to choose?

RAM is the easiest and most effective upgrade for most laptops. Even budget models Lenovo IdeaPad or HP Pavilion often have a free slot for an additional bracket. The main thing is to know the limitations of your motherboard.

How to check compatibility:

1. Find out your motherboard model (via msinfo32 on the command line or CPU-Z).
2. Check the specifications on the manufacturer's website (for example, ASUS or Lenovo). Look for lines like Max RAM: 32GB or DDR4 3200MHz.
3. Determine the memory type: DDR3, DDR4 or DDR5 (in laptops 2023–2026). You can't mix different generations!

Laptop type	Max. amount of RAM	Memory type	Examples of models
Office (budget)	8–16 GB	DDR4 2400–2666 MHz	Lenovo ThinkPad E14, HP 250 G8
Gaming	32–64 GB	DDR4 3200 MHz / DDR5 4800 MHz	ASUS TUF Gaming, MSI GF63
Ultrabooks	Soldered (not replaceable)	LPDDR4X/LPDDR5	Apple MacBook Air, Dell XPS 13
Business class	16–32 GB	DDR4 2933 MHz (ECC)	HP EliteBook, Lenovo ThinkPad P1

Important details:

• 🔧 If on a laptop one strip (for example, 8 GB), add a second one of the same size to work in two-channel mode - this will speed up productivity by 15–20%.
• ⚠️ In some models (for example, Acer Swift 3) the RAM slot may be occupied by the factory slot, and the second slot may be empty. Check!
• 💡 For laptops with Intel Core i3/i5/i7 12–13 generation And AMD Ryzen 5000/6000 optimally 16–32 GB DDR4 3200 MHz.

3. Replacing HDD with SSD: how to speed up a laptop 5 times?

Transition from HDD on SSD - the most noticeable upgrade for older laptops. The system will boot in 10 seconds, and programs will open instantly. But there are several pitfalls:

• 🔄 Form factor: Used in thin laptops M.2 NVMe (For example, Samsung 980 Pro), and in the old ones - 2.5" SATA (For example, Crucial MX500). Check which slot is free!
• 📏 Capacity: For Windows 11, 256GB is enough, but if you are storing games or videos, go for 1TB.
• 🔧 System cloning: You can transfer data from HDD to SSD via Macrium Reflect or Clonezilla (free).
• ⚠️ BIOS Compatible: some older laptops (before 2015) do not support NVMe — you need firmware or an adapter.

Step-by-step instructions for replacement:

1. Download the Windows image to a USB flash drive (on the website Microsoft) or clone the current disk.
2. Unscrew the back cover of the laptop and find the drive. B M.2- the slot usually has a small screw for fixing it.
3. Carefully remove the old drive (do not pull the wires!) and insert the new one. For 2.5" SATA a sled may be needed.
4. Connect the laptop to the network and turn it on. If the system does not boot, go to BIOS (F2/Del at startup) and select the boot device.

What to do if the BIOS does not recognize the new SSD?

If after installing the SSD the laptop does not boot or the disk does not appear in the BIOS:

1. Check whether the drive is inserted correctly (the contacts must be clean).

2. Update the BIOS to the latest version (instructions on the manufacturer's website).

3. For old laptops (HP ProBook 450 G2 and similar) you may need to enable the mode AHCI instead of IDE in BIOS settings.

4. If used NVMe, but the laptop does not support it, try installing Windows in Legacy (not UEFI).

In laptops Apple MacBook Pro until 2015 (with connector PCIe 2.0 x4) SSD speed is limited to 1.5 GB/s - newer drives (for example, Samsung 970 EVO Plus) will work slower than factory ones.

4. Battery upgrade: when to change and how to extend life?

The average laptop battery life is 3–5 years (or 500–1000 charge cycles). If the laptop holds a charge for less than an hour or suddenly turns off at 20%, it’s time to think about replacing it. But not all batteries can be changed independently:

• 🔋 Removable batteries (found in Lenovo ThinkPad T-series or Dell Latitude): easy to replace, just snap off the latches.
• 🔧 Built-in batteries (most modern laptops): disassembly and disconnection of the cable will be required.
• ⚠️ Batteries in MacBook (2016 and newer): glued to the body, requires a special tool to replace (iFixit sells sets).
• 🔌 Universal replacements: for example, a battery from HP Pavilion 15 often approaches HP 250 G7 - check by model number (written on the label).

How to extend the life of a new battery:

• 📉 Keep the charge between 20% and 80% - full discharges/charges will shorten the lifespan.
• 🔥 Do not use the laptop on soft surfaces (pillow, blanket) - overheating kills the battery.
• ❄️ Store your laptop at a temperature of 10–30°C. In cold weather (-10°C) the battery can lose up to 50% of its capacity.
• 🔌 If the laptop is constantly connected to the network, reduce the maximum charge to 80% in the settings (MyASUS, Lenovo Vantage or via BIOS).

5. Updating the cooling system: when cleaning doesn't help?

If the laptop overheats (shuts down under load or runs at low frequencies), the problem may be:

• 🧹 Dusty radiator (cleaned with compressed air or disassembly).
• 🧴 Dried thermal paste (changes to Arctic MX-6 or Noctua NT-H2).
• 🔧 Worn out fans (can be replaced with quieter ones, for example, from Delta or Sunon).
• ⚠️ Thermal pads (in graphics laptops they “dull” over time and stop transmitting heat).

Step-by-step instructions for replacing thermal paste:

1. Turn off the laptop, remove the battery (if removable) and the back cover.
2. Disconnect the cooler and carefully remove the heatsink from the processor/video card.
3. Remove old paste with a cloth soaked in isopropyl alcohol (90%+).
4. Apply a thin layer of new paste (about the size of a grain of rice) and assemble everything in reverse order.

For gaming laptops (ASUS ROG Strix, MSI GE76) useful to install copper thermal pads instead of standard ones (for example, Thermal Grizzly Minus Pad 8). This will reduce the GPU temperature by 5-10°C.

6. Is it possible to upgrade the processor or video card?

In 90% of laptops processor is soldered to the motherboard and cannot be replaced. Exceptions:

• 🖥️ Old laptops (until 2016) with sockets PGA or BGA (For example, Intel Core i7-4700MQ in Dell Inspiron 15).
• 🎮 Gaming laptops with socket LGA (rarely, for example, Clevo P775TM1).
• ⚠️ Mobile processors (Intel H-series or AMD Ryzen H) often have TDP limitations - installing a more powerful chip can lead to overheating.

With video cards it’s even more difficult:

• 🔧 B 10% gaming laptops (For example, Alienware Area-51m or Eurocom) slot is used MXM, allowing you to replace the GPU.
• 💡 The cost of such a video card (for example, NVIDIA RTX 3080 Mobile) can reach $1,500, which is comparable to the price of a new laptop.
• ⚠️ Attention: even if the slot MXM yes, the manufacturer can block replacement at the BIOS level (relevant for MSI GT76 and similar).

If your laptop does not fall into this 10%, forget about upgrading the CPU/GPU. It's better to sell it and add money for a new model.

7. Updating BIOS: Risks and Benefits

BIOS firmware can:

• ✅ Add support for new processors (for example, 13th generation Intel Core into old motherboards).
• ✅ Fix bugs with fan control or battery charging.
• ✅ Unlock hidden settings (for example, the ability to disable Secure Boot).
• ⚠️ Attention: A failed BIOS update can turn your laptop into a brick. Always use stable power supply (not battery powered!) and official software from the manufacturer's website.

How to update BIOS safely:

1. Download the latest BIOS version for your model from the official website (ASUS, Lenovo etc.).
2. Connect your laptop to the network and close all programs.
3. Run the firmware file (usually has the extension .exe or .fd).
4. Don't interrupt the process! Wait for the automatic reboot.

After updating, reset BIOS settings to factory defaults (Load Default Settings) and configure again.

FAQ: Frequently asked questions about laptop upgrades

Is it possible to put two SSDs in a laptop: one M.2 and the other 2.5" SATA?

Yes, if the laptop has both slots. For example, in Lenovo Legion 5 or HP Omen 15 often provided M.2 NVMe for the system and 2.5" SATA for storage. Check the specifications of your model - sometimes the second slot is occupied by a Wi-Fi module.

Is it worth upgrading a 2015 laptop?

Depends on the model. If this is a business laptop (ThinkPad T450, Dell Latitude E7450) - yes: you can add SSD, RAM and replace the battery. If it's budget Acer Aspire E5 — it’s better to buy a new one, since even after an upgrade it will lose performance to modern laptops.

How to transfer Windows to a new SSD without reinstalling?

Use cloning programs:

1. Macrium Reflect Free - simple interface, supports NVMe.
2. Clonezilla - free, but more difficult to set up.
3. Samsung Data Migration - if you have a Samsung SSD.

Important: after cloning, disconnect the old disk, otherwise bootloader conflicts may occur.

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

Check:

• Are all cables and connectors connected correctly (especially the motherboard power supply).
• Are the RAM or SSD contacts shorted (relevant if you touched components without an antistatic wrist strap).
• Are the BIOS settings lost (try resetting them by removing the CMOS battery for 10 seconds).

If the laptop still does not work, contact a service center.

Which SSD is better to choose for a laptop: NVMe or SATA?

NVMe (M.2) 5–10 times faster SATA, but only if your laptop supports PCIe 3.0/4.0. For office tasks (Word, Excel) it will be enough SATA SSD (For example, Crucial BX500), but for games, video editing or programming, take NVMe (For example, WD Black SN850X or Samsung 990 Pro).
