What can be changed in a laptop: a complete upgrade guide

Over time, the laptop begins to slow down, overheat, or discharge too quickly. Instead of buying a new device, many users prefer modernize existing laptop - replace outdated components with more powerful or serviceable ones. However, not every part in a laptop is replaceable: Manufacturers often solder key components to the motherboard to reduce the thickness of the case or save on repairability.

In this article we will look in detail at what components can you change in a laptop yourself?, and which ones - only at the service center (or not at all). You will learn how to determine the compatibility of spare parts, avoid common mistakes during disassembly and not void the warranty. We will pay special attention security: Working with electronics requires care, and incorrect actions can lead to a short circuit or failure of the device.

1. Random access memory (RAM): how to increase performance

One of the simplest and most effective upgrades is replacing or adding RAM sticks. Most laptops (except ultrabooks and models with soldered memory) allow you to increase the amount of RAM, which is especially important for working with graphic editors, virtual machines or modern games. For example, transition from 8 GB on 16–32 GB can speed up video rendering in Adobe Premiere by 20–40%.

Before purchasing new memory, check:

• 🔍 Memory type: DDR3, DDR4 or DDR5 (indicated in the laptop specifications or on the manufacturer’s website). You can't mix different generations!
• 📏 Form factor: for laptops used SO-DIMM, not desktop DIMM.
• ⚡ Frequency: if the motherboard supports 3200 MHz, but you install 2400 MHz, the memory will operate at a reduced frequency.
• 🔄 Number of slots: Some laptops only have one slot, and to upgrade you will have to replace the existing bracket rather than adding a second one.

To find out your current RAM configuration, use utilities like CPU-Z (tab Memory) or AIDA64. Information can also be found in Windows Task Manager (section Performance → Memory).

⚠️ Attention: In laptops Apple MacBook (starting from 2016), Dell XPS 13/15 (models after 2020) and many ASUS ZenBook The memory is soldered to the motherboard. Attempting to replace it will result in damage!

2. Storage: SSD instead of HDD and storage upgrade

Replacing the hard drive (HDD) to a solid state drive (SSD) is the most noticeable upgrade for an old laptop. SSD speeds up Windows loading by 3-5 times, and launching programs (for example, Photoshop or AutoCAD) happens almost instantly. In addition, SSDs are shock-resistant, quiet, and consume less power, resulting in longer battery life.

There are three types of SSDs used in modern laptops:

• 💽 2.5" SATA - universal format, compatible with most laptops (speed up to 550 MB/s).
• 🔌 M.2 SATA - compact connector, but the same speed as 2.5" (suitable for thin laptops).
• ⚡ M.2 NVMe - the fastest option (speed from 3000 MB/s), but requires motherboard support (check the specs!).

If your laptop has a free slot M.2, you can install an SSD in addition to the existing HDD by organizing two-level storage: the system and programs are on the SSD, and the files are on the HDD. For this purpose in Windows use the function Storage Spaces, and in Linux — LVM.

⚠️ Attention: When replacing a drive in laptops with BitLocker (Windows Pro) or FileVault (macOS) required disable encryption before removing the disc! Otherwise, the data will not be available on the new SSD.

Unplug the laptop and remove the battery (if removable)

Back up your data (to an external drive or cloud)

Prepare a screwdriver with a magnetic tip (usually T5 or PH0)

Check the availability of an adapter for M.2 (if needed)

Download a bootable USB flash drive with Windows/Linux for a clean installation-->

3. Battery: when and how to change it

A laptop battery loses capacity over time: after 2–3 years, it can only hold a charge of 30–50% of its original value. If your laptop turns off when unplugged or runs out of power within 1-2 hours, it’s time to think about replacing it. However, not all batteries are removable: in ultrabooks (for example, MacBook Air or Lenovo Yoga) the battery is glued to the case and will require disassembly to replace.

Before purchasing a new battery:

• 🔋 Check it out laptop model And battery part number (written on an old battery or in BIOS).
• 🔌 Make sure the new battery has the same capacity (in Wh or mAh) and voltage (usually 11.1V or 14.8V).
• 🛡️ Buy only from official suppliers or trusted sellers - cheap Chinese analogues may swell or ignite.

To calibrate a new battery after installation:

1. Charge it up to 100%.
2. Unplug the charger and discharge to 0% (until the laptop turns off).
3. Repeat the cycle 2-3 times - this will help the controller correctly determine the capacity.

4. Keyboard and touchpad: repair or replacement

The keyboard is one of the most vulnerable parts of a laptop. Over time, the keys begin to stick, fall off, or stop working. In most cases, individual keys can be replaced (they are secured with latches), but if the backing or cable is damaged, a complete replacement will be required. The same goes for the touchpad - it can be changed if it is not soldered into the motherboard (as in some HP Spectre or Acer Swift).

Reasons for replacement:

• ☕ Liquid ingress (even after drying, contacts may oxidize).
• 🔨 Mechanical damage (cracks, chips).
• 🖱️ Touchpad malfunction (does not respond to touches, spontaneous clicks).
• 🔤 Wear of keys (erased symbols, tight movement).

To replace the keyboard:

1. Turn off the laptop and remove the battery.
2. Gently pry the keyboard latches with a plastic spatula (starting from the top edge).
3. Disconnect the cable by pulling the tab (do not pull the wires!).
4. Install a new keyboard and connect the cable.

⚠️ Attention: In laptops Apple (starting from 2015) and some models Dell Latitude The keyboard is integrated with the battery. Replacement requires complete disassembly and risks damaging the battery!

5. Screen: replacing the matrix or the entire display

A cracked screen, dead pixels, or backlight problems are common reasons to replace your display. In most laptops, the matrix is attached to the lid with latches, and the cable is connected to the motherboard. However, in ultrabooks (for example, Lenovo ThinkPad X1 Carbon or HP EliteBook) the screen may be glued, making repairs more difficult.

What to look for when choosing a new matrix:

• 📺 Resolution and diagonal: must match the original (for example, 1920×1080 for 15.6").
• 🔦 Backlight type: LED or OLED (the second option is more expensive, but has more contrast).
• 🔄 Refresh rate: if original 60 Hz, and you install 144 Hz, may not work without BIOS firmware.
• 🔌 Loop type: 30-pin or 40-pin (check with the seller).

Replacement process:

1. Remove the rubber plugs at the edges of the screen (the screws are hidden under them).
2. Unscrew the screws and carefully separate the matrix from the cover (use screen suction cups).
3. Disconnect the backlight and matrix cables (they are fragile!).
4. Install a new matrix and reassemble in reverse order.

6. Cooling system: cleaning and replacing thermal paste

Laptop overheating is one of the main reasons for slow performance and sudden shutdowns. Dust, dried thermal paste, or a faulty fan can raise the processor temperature to 90–100°C, which leads to throttling (automatic frequency reduction). Solution - cooling system cleaning and replacing thermal paste.

What you will need:

• 🧹 Brush or can of compressed air.
• 🧴 Thermal paste (Arctic MX-6, Noctua NT-H2 or Thermal Grizzly Kryonaut).
• 🔧 Screwdriver and plastic spatula.
• 🧻 Lint-free wipes and isopropyl alcohol (90%+).

Step by step instructions:

1. Turn off the laptop, remove the battery, and remove the bottom cover.
2. Clean the radiator and fan from dust (you can use a vacuum cleaner at minimum power).
3. Remove the cooler, remove the old thermal paste with alcohol and apply a new one (a layer thick ~0.5 mm).
4. Check the rotation of the fan - if it does not spin, replace it.

⚠️ Attention: In laptops Apple (starting from 2018) and some MSI The heatsinks are soldered to the chip. Replacing thermal paste yourself in such models can damage the motherboard!

7. Processor and video card: can it be upgraded?

Replacing the processor (CPU) or video card (GPU) on a laptop is a difficult and often impossible task. In 90% of modern laptops these components soldered to the motherboard, and replacing them requires specialized equipment (for example, BGA stations) and skills.

Exceptions:

• 🖥️ Some desktop replacements (For example, Dell Precision or HP ZBook) have socket processors (LGA 1151, LGA 1200).
• 🎮 Gaming laptops (ASUS ROG, MSI GT) sometimes they allow you to replace MXM video card, but this is rare.

Before purchasing a new processor, check:

• 🔧 Socket (For example, BGA 1440 for Intel 12th generation).
• ⚡ TDP (thermal package) - if you install a processor with TDP 45W into a laptop designed for 15W, it will overheat.
• 🔄 BIOS support - Some motherboards require a firmware update to work with new CPUs.

• 🔊 Speakers — if the sound wheezes or disappears, the problem may be torn wires or damaged membranes. Replacing the speakers in most laptops is no more difficult than replacing the keyboard.
• 📷 Webcam — if the image is blurry or the camera does not turn on, it can be replaced (usually attached with latches to the top frame of the screen).
• 📶 Wi-Fi/Bluetooth module - if the laptop does not connect to the network or constantly loses connection, the adapter may be to blame. Modern modules (for example, Intel AX200) support Wi-Fi 6 And Bluetooth 5.2.
• 🔌 Charging port - if the laptop does not charge, the problem may be in the connector DC-in or USB-C (in new models). Replacing the port requires soldering.
