ASUS ExpertBook P5 P5405 is ASUS's Copilot+ business notebook built for professionals who want a light 14 inch laptop with strong AI performance and all day battery life. The model discussed here is the ExpertBook P5 P5405CSA in Misty Gray with an Intel Core Ultra processor, QHD+ display and Windows 11.
Design, Display And Build For Work
The ExpertBook P5 P5405 centers on a 14.0 inch WQXGA 2560 x 1600 IPS display with a 16:10 aspect ratio and 144 Hz refresh rate, giving more vertical space for documents and smoother scrolling in productivity apps.ASUS's launch specification sheet lists brightness at 400 nits and coverage of 100% sRGB, which suits office lighting and color accurate work such as presentations and light photo editing.
The chassis uses aluminum and is finished in a Misty Gray color, and ASUS quotes dimensions of 12.28 in x 8.79 in x 0.65 in with a weight of about 2.8 lb, so it stays in the thin-and-light business category rather than ultraportable extremes.The same ASUS spec table also notes a 63 Wh battery and a 65 W USB-C power adapter, meaning the laptop is designed to balance runtime and charging speed without a bulky power brick.
Intel Core Ultra Platform And AI Features
Inside, the ExpertBook P5 P5405 line offers up to an Intel Core Ultra 7 258V processor and an Intel Core Ultra 5 226V option, both part of Intel's Series 2 family with a built-in Intel AI Boost NPU (neural processing unit).ASUS's technical specifications page specify that the Core Ultra 7 258V configuration pairs with 32 GB of LPDDR5X memory, while the Core Ultra 5 226V configuration comes with 16 GB of LPDDR5X, both soldered onboard.
Graphics are handled by Intel Arc 140V or 130V integrated GPUs depending on configuration, and the Intel AI Boost NPU can reach up to 47 TOPS in the higher end model for AI workloads that meet Microsoft's Copilot+ PC requirements.The ASUS launch release positions the ExpertBook P5 as ASUS's first Copilot+ PC for work and highlights that it delivers up to a 3x AI performance boost over the prior generation, enabled by the NPU and AI tuned platform.
On the software side, the laptop ships with Windows 11 Home or Windows 11 Pro and includes ASUS AI ExpertMeet and MyASUS among the built in applications.The ASUS US eShop listing describes AI ExpertMeet as a meeting assistant requiring at least 12 GB of RAM and emphasizes the dedicated Copilot key for launching Microsoft Copilot features such as summarizing content and generating drafts within Windows.
Memory, Storage And Connectivity Options
For memory, ASUS specifies that the ExpertBook P5 P5405 can be configured with 16 GB or 32 GB of LPDDR5X RAM mounted on the package, with the maximum capacity equal to the preinstalled amount.The tech specs page specify storage options of 512 GB or 1 TB NVMe PCIe 4.0 SSDs in an M.2 2280 slot, plus an additional M.2 2230 PCIe 4.0 slot for expansion or IT managed installations.
The I/O port selection aims to cover both modern and legacy office needs. ASUS lists two Thunderbolt 4 USB-C ports that support display output and power delivery, two USB 3.2 Gen 2 Type-A ports, a full size HDMI 2.1 port and a 3.5 mm combo audio jack.The launch spec table adds that the webcam is a Full HD camera with IR capability for Windows Hello face sign in, and the audio subsystem includes a smart amp, built in speakers and array microphones tuned for conferencing.
Wireless connectivity includes Wi-Fi 6E and, in some configurations tested by reviewers, Wi-Fi 7, along with Bluetooth 5.3 or 5.4 depending on region and SKU.A review of the ExpertBook P5 notes that the machine uses Intel's latest platform with Wi-Fi 6E or Wi-Fi 7 options and confirms a 63 Wh battery, which is consistent with ASUS's own technical documentation.
Battery Life And Performance Compared With Peers
In independent testing, the ExpertBook P5 P5405 has shown strong battery life within the Copilot+ PC landscape. One lab report measured about 14 hours and 22 minutes of runtime in a productivity benchmark, indicating that the 63 Wh battery and efficiency tuned Intel platform can support a full workday away from an outlet.Lab testing reported by a US notebook review outlet contrasts this with many earlier Intel business laptops that fell under 12 hours in similar tests.
Pricewise, ASUS positions the ExpertBook P5 P5405 between mainstream consumer notebooks and higher priced premium business machines. The launch press release lists a US MSRP starting at $1099.99 and a band of $1099.99 to $1489.99 depending on configuration.ASUS's US announcement states that the ExpertBook P5 is available through the ASUS Store and several major retailers, which places it in the expected range for a 14 inch business laptop with modern Intel silicon and QHD+ display.
A detailed US review describes a configuration with an Intel Core Ultra 5 226V, 16 GB of RAM and a 512 GB SSD starting at about $1100 and a higher end Core Ultra 7 258V, 32 GB RAM and 1 TB SSD configuration at about $1300.The same US review frames the ExpertBook P5 as a business notebook priced competitively against other Copilot+ PCs and traditional business laptops, noting its QHD+ 144 Hz display as a differentiator versus many competitors that ship with 60 Hz panels.
