Ultimate durability is a core value that ASUS ExpertBook laptops deliver for business users, ensuring your valuable assets will survive whatever daily rigours, 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.

Low Temperature Operation Endure -31°C for 3 days with power on
High Temperature Operation Endure 43°C for 3 days, with power on

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.
easy data entry
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.
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.
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!
