ASUS Zenbook S 14 in-depth review

The ASUS Zenbook S 14 UX5406 is not just an ultra-thin well-crafted laptop. The new Intel Lunar Lake CPUs power it (these are also known as Intel Core Ultra 200V or Core Ultra (Series 2)). You can choose from three chips with 17W base power and the top dog is a 30W model. The main focus here isn't top-of-the-line performance, this time it's all about efficiency and power management. Here, Intel ditches Hyper-Threading and that's why you get four P cores (Lion Cove) and the same amount of LP E cores (Skymont). Intel's Thread Director firmware hints to the OS about which and how many cores are best suited for each task and load. The LPDDR5x memory is placed onto the CPU which reduces latency and frees some space on the motherboard allowing the manufacturers to create even thinner devices. Th[...]

Disassembly, maintenance and upgrade options

Opening the DeviceUndo the 10 Torx-head screws securing the bottom panel. If you’re confident, the easiest way to start is from the cutouts. Insert a thin plastic tool at a 45-degree angle, with the top side pointing inside the bottom panel. Pop half of the plate by lifting the tool, then work your way around the sides, back, and front. Alternatively, pry the top two edges (but note the stiff internal clips), then continue with the back, sides, and front.More info: Be cautious not to insert the tool horizontally as it may damage the speakers. Here's the internal look o[...]
