Today, several years after mass production, the issue of the relevance of these machines is especially acute. Many owners are looking for ways to extend the life of their devices, and potential buyers in the secondary market want to understand whether the purchase is ASUS X540 mistake. In this article we will analyze in detail the design features, real upgrade possibilities and typical problems faced by users of this line.
Design features and housing design
Appearance ASUS X540 made in a strict, but not devoid of elegance style. The body is predominantly plastic, which is the norm for this price segment, but the build quality is surprisingly high. The screen cover often has a textured finish that doesn't attract fingerprints and gives the device a more premium look compared to the smooth, glossy counterparts of competitors.
The case materials are rigid enough to avoid the squishing effect when carried, but they are sensitive to shock. The thin plastic on the ends can crack if handled improperly or squeezed too hard in a backpack. The screen generally has the bezel thickness typical of 2015-2016, which makes the device a little bulkier than modern Ultrabooks, but is compensated by a reliable opening hinge.
- 💡 The weight of the device is about 2.1 kg, which makes it comfortable enough to carry for short trips.
- 💡 The kit often includes a power supply with a connector that is resistant to frequent pulling out, which reduces the risk of the socket breaking.
- 💡 The stand at the bottom has rubberized feet that prevent sliding on the table during intensive typing.
Performance and hardware platform
Under the hood ASUS X540 hiding a wide range of processors, from low-power Celeron to more powerful sixth-generation Core i3 and i5. The scenario for using a laptop depends on the choice of processor. Models with Intel Celeron N3060 or N3350 processors are suitable exclusively for web surfing and working with documents, while versions based on the Core i5-6200U are capable of light video editing and running undemanding games.
RAM in most configurations is represented by DDR3L or DDR4 modules, which provides some flexibility when upgrading. However, it is worth considering that in some versions one channel is soldered on the board, and the second is available for expansion. This means that the maximum memory capacity may be limited by the specifics of the motherboard, and installing two 8 GB sticks may not give the expected increase if one channel is fixed at 4 GB.
- 🚀 Intel Skylake series processors provide decent energy efficiency and heat dissipation.
- 🚀 Integrated Intel HD Graphics 520 allows you to run old games at low settings.
- 🚀 The presence of an M.2 slot for SSD (in some revisions) significantly speeds up the system compared to HDD.
It's important to note that actual performance is highly dependent on the cooling system. B ASUS X540 It uses one heat pipe and a fan, which can be noisy under load.

Display and multimedia capabilities
Laptop screen ASUS X540 most often has a diagonal of 15.6 inches and a Full HD resolution (1920×1080). This is a standard solution that provides comfortable work with text and watching movies in good quality. However, the quality of the matrix can vary greatly depending on the specific batch and region of delivery. Budget versions often have TN matrices with narrow viewing angles, while more expensive versions boast IPS panels.
Viewing angles on TN matrices leave much to be desired: when viewed from the side, the image is inverted or loses contrast. Brightness is typically around 220-250 nits, which is good enough for indoor use, but in direct sunlight the screen becomes almost unreadable. Color reproduction also often suffers from lack of saturation, making this model unsuitable for professional graphics work.
- 📺 The screen is perfect for watching movies in the dark due to sufficient contrast.
- 📺 The presence of ASUS Splendid technology allows you to adjust the color temperature through the software.
- 📺 The 0.3 MP webcam provides a very grainy picture, suitable only for emergency calls.
The sound subsystem also has its own characteristics. The built-in speakers, although SonicMaster certified, are not capable of delivering deep bass. The sound may seem flat at maximum volume, so using external headphones or speakers is highly recommended for a better music experience.
Disassembly and upgrade options
One of the main advantages of the series ASUS X540 is the relative ease of access to internal components. To access the RAM and hard drive, it is not necessary to remove the entire bottom cover; just unscrew a few screws in a special hatch. This allows owners to upgrade the device themselves without the risk of damage to the case or loss of warranty (if it is still valid).
The cooling system also requires periodic cleaning. Over time, the heatsink becomes clogged with dust, which leads to processor overheating and throttling. The disassembly process involves removing the keyboard, which is the most difficult step. The keyboard is held on by latches, and careless handling can lead to their breakage. It is recommended to use a plastic card to carefully pry the keys around the perimeter.
☑️ Preparing to clean the cooling system
- 🔧 When replacing thermal paste, use high-quality compounds, for example, Arctic MX-4 or Thermal Grizzly.
- 🔧 The hard drive slot supports 2.5 inch formats, but the height of the drive should not exceed 9.5 mm.
- 🔧 The M.2 slot supports 2280 format drives, which makes it possible to install fast NVMe SSDs.
Typical problems and solutions
Owners ASUS X540 often encounter a number of system and hardware problems. One of the most common is overheating and fan noise. This is due to the fact that the factory thermal paste dries out over time, and the ventilation grilles become clogged with dust. Solving the problem requires completely disassembling the laptop, cleaning the radiator and replacing the thermal interface.
Another common problem is the touchpad or keyboard failing. In some cases, this is a software failure that can be solved by reinstalling the drivers via Device Manager. However, if the problem occurs after liquid ingress, the board will need to be professionally cleaned and possibly the controller replaced.
⚠️ Attention: If the laptop does not turn on and the indicators do not light up, check the integrity of the fuse on the power board and the condition of the DC-in connector, which often breaks due to mechanical stress.
Also worth mentioning are the problems with the screen. There are cases when, when opening the lid, the image disappears or stripes appear. This is a sign of damage to the matrix cable that passes through the loops. Replacing a cable is not the most difficult task, but it requires care when disconnecting fragile connectors.
Common mistakes when replacing thermal paste yourself
Mistake 1: Using too much paste, which causes it to squeeze out under the processor. Mistake 2: Using abrasive products to clean the crystal, which damages the protective layer. Mistake 3: Uneven distribution of paste, leaving air pockets.
Operation optimization and software
For stable operation of the laptop, you need to configure the software correctly. Utility ASUS Live Update allows you to receive timely driver and BIOS updates, which is critical for correcting compatibility errors. It is also worth paying attention to pre-installed software, which can slow down the system.
Disabling unnecessary services and startup programs via Task Manager can significantly speed up Windows boot time. If you have Windows 10 or 11 installed on your device, it is recommended to disable transparency and animation effects in the system settings. This will reduce the load on the integrated graphics and processor.
