* As of Mar 1, 2019 based on internal ASUS market analysis comparing ASUS ExpertBook P3540 laptop size to competing products in its class (laptops with a 15” screen) from vendors including Dell, HP, and Lenovo.

Non-stop performance for every need
P3540 gives you day-long power so you can get more done, wherever you are. Its high-capacity 70Wh battery can last up to 16 hours1 on a single charge, so you can stay productive for longer when you’re far away from power outlets. For effortless performance, P3450 is powered by the latest 8th Gen Intel® Core™ processors, and offers an ultrafast SSD plus a high-capacity HDD, giving you responsive storage with no shortage of room for your files.

Maximum workspace, minimum burden
The expansive 15-inch NanoEdge display has extra-slim bezels that help make P3540 incredibly compact and pleasingly light, for take-anywhere mobility. Its precision-crafted chassis is finished in elegantly classic gray, creating a truly professional impression wherever you go.

Comprehensive and reliable connections
When you’re working on the go, full connectivity is vital. P3540 has a comprehensive set of I/O ports, including four USB ports and an SD card reader, along with HDMI, LAN and VGA ports for easy data transfers and versatile peripheral connections. For enhanced reliability, the solidly constructed ports are tested to endure over 5000 insertions.

Ready for action
Ultimate durability is a core value that ASUS ExpertBook laptops deliver for business users, ensuring your valuable assets will survive whatever daily rigors, accidental impacts, or hostile environments they encounter. All ASUS ExpertBook series laptops are strongly built and strictly quality-tested in accordance with US MIL-STD 810G military standards and ASUS internal quality tests, which include physical impact tests like drops, knocks, and spills, and exposure to extremes of altitude, temperature, and humidity.

Robust and versatile 180° hinge
The hinge can be a weak point on standard laptops, but not on P3540. It’s built to withstand use in tough business environments, with a full 180° of movement: this not only reduces stress on the hinge, but allows it to lay flat for easy screen sharing. The hinge is also torture-tested with 50,000 open/close cycles to ensure maximum durability.

Ergonomically designed keyboard
With any ASUS ExpertBook Laptops, your comfort is one of our top priorities, P3540 goes the extra mile with its exclusive ErgoLift hinge that automatically tilts the keyboard to a comfortable typing position, widely spaced, long-travel keys* that gives a more responsive and comfortable desktop-like typing experience, and a standard full-size numeric keypad for speedy data entry.
* Key travel: The vertical distance a key moves when pressed. Longer key travel gives a more natural desktop-like feel.

Safeguard your data and assets
Data is the lifeblood of your business, which is why ASUS ExpertBook laptops offer comprehensive business-grade security. P3540 offers rock-solid security from physical hardware protection to identity security with a Kensington lock slot, TPM 2.0 chip, webcam privacy shield, and a fingerprint sensor.

Webcam privacy shield
For extra peace of mind when working in sensitive environments, the webcam on P3540 has an integrated privacy shield that simply slides over the webcam to stop it being used.

TPM 2.0
The TPM 2.0 security chip securely stores authentication information (such as passwords or encryption keys) used by software to protect important data and transactions. It can also completely block access to a PC if a security threat is detected at boot-up.

Fingerprint sensor
Accessing your P3540 couldn’t be easier or more secure, thanks to Windows Hello technology and the fingerprint sensor next to the touchpad. Now there’s no need to type in your password every time to log in — a single touch is all it takes!

Maximum support, minimum effort
The ASUS ExpertBook Service Package3 offers a wider range of solutions that go beyond the standard warranty to meet the needs of business-critical IT environments. The extended offerings protect your business — not just the hardware, but also let you customize a service solution that best meets your needs.

One-stop management
ASUS ExpertBook laptops are designed to help simplify asset-management processes for both MIS staff and end users. The exclusive ASUS Business Manager — an easy-to-use PC management tool — lets you easily backup and restore data, apply automatic updates, or diagnose system health. Additionally, the optional ASUS Control Center is a centralized management suite that includes remote management, hardware and software monitoring, and easy-to-use optimization features.
