Key Features:

• Display: Typically comes with a 14-inch display, available in various resolutions including Full HD (1920 x 1080). The screen offers decent clarity and brightness, suitable for most business tasks.
• Processor: Equipped with Intel Core i5-6200U, a sixth-generation (Skylake) processor. This is a dual-core CPU with Hyper-Threading, designed for efficient multitasking and moderate computing needs.
• Memory: Often comes with 8GB of RAM, which is adequate for most office applications, multitasking, and moderate data processing.
• Storage: Commonly found with either a 256GB or 512GB SSD, providing fast boot times and quick access to files. Some configurations might also come with traditional HDDs, but SSDs are preferable for performance.
• Build and Design: Features a robust, durable build with a magnesium alloy chassis. The 840 G3 is known for its solid construction and reliability, suitable for business environments.
• Keyboard and Touchpad: The keyboard is typically full-sized with a good tactile feel, and the touchpad is responsive. Some models might include a pointing stick in the middle of the keyboard (HP’s Pointstick).
• Ports and Connectivity: Offers a good range of ports, including USB 3.0, USB-C (depending on the specific configuration), HDMI, VGA, and an Ethernet port. This variety makes it versatile for connecting to various peripherals and external displays.
• Security Features: Includes options for enhanced security, such as a fingerprint reader and TPM (Trusted Platform Module) for secure data encryption.
• Battery Life: Generally decent, with typical use cases providing around 7-10 hours of battery life, though this can vary based on usage and battery health over time.

Considerations:

• Performance: The Core i5-6200U is capable for many business tasks and moderate multitasking, but it is from an older generation of CPUs. If you're running more demanding applications or need higher performance, you might find it somewhat limiting compared to newer processors.
• Operating System Compatibility: The EliteBook 840 G3 should be compatible with Windows 10, and it might support upgrades to Windows 11, though checking for specific compatibility is advisable.
• Upgradability: The RAM and storage can typically be upgraded, which might be beneficial if you find the existing configuration lacking.
