Extremes of temperature, altitude and humidity can be bad news for a laptop, so every ExpertBook goes through a series of tough climatic tests to make sure they can survive in harsh environments, whether they're turned on or off. ASUS bake them in desert-like heat, freeze them down to super-chilly temperatures, subject them to steamy humidity and check if they can survive at dizzying altitude – so they’re fit to work wherever you might travel.

ASUS ensures that every component of your ExpertBook laptop delivers long and reliable service, no matter how tough the going gets. They pound the keyboard with up to 10-million keystrokes, test the hinges with up to 20,000 open-and-close cycles, subject the chassis to 50,000 twisting tests to mimic those one-handed dashes to the meeting room, and ensure the touchscreen has a precise and consistent response. ASUS also connect and disconnect the I/O ports 5,000 times for endurance, and check that performance isn’t affected by cable quality. Finally, ASUS pressure-test the display using up to 30 kg of force on the lid and the underside of the chassis. Only if it survives all these is a laptop deemed worthy of the ASUS badge.
