Lenovo ThinkPad T480 14" Vs Lenovo ThinkPad T490s 14"

The Lenovo ThinkPad T480, released in 2018, and the Lenovo ThinkPad T490s, launched in 2019, are both 14-inch business-oriented laptops from Lenovo's reputable ThinkPad T-series. While sharing the core ThinkPad philosophy of durability and productivity, the T490s distinguishes itself with a more streamlined design and updated display options, whereas the T480 offers greater internal upgradeability and a unique battery system. Both devices typically run on the Windows operating system, providing a familiar and robust computing environment for professional use.

When considering the longevity of these laptops, several factors come into play, including their release timelines, operating system support, and physical design for repair and upgrades. The T480 and T490s, being from consecutive generations, offer similar expected software support durations, primarily dictated by Microsoft's Windows lifecycle.

• Release Timeline: The ThinkPad T480 was released in 2018, while the T490s followed in 2019. This means the T490s will likely receive official operating system updates for approximately one year longer than the T480, extending its software longevity. [1, 2, 4]
• Repairability and Upgradability: The T480 is generally considered more user-serviceable, featuring two accessible RAM slots and a unique hot-swappable external battery system. This design allows for easier component replacement and memory upgrades, potentially extending its practical lifespan. [13, 30, 31, 35, 36] In contrast, the T490s has its RAM soldered directly to the motherboard, limiting memory upgrades, though its SSD and internal battery remain replaceable. [4, 11, 16, 18, 37, 38, 39]
• Build Quality: Both models uphold the ThinkPad reputation for robust construction, having undergone MIL-STD-810G military testing for durability against various environmental stresses. This rigorous testing suggests both laptops are built to withstand demanding daily use. [4, 8, 10, 19]

The performance of the ThinkPad T480 and T490s is well-suited for general business and productivity tasks, with both models featuring 8th generation Intel Core processors. The practical differences in day-to-day responsiveness and handling of demanding applications are subtle but present.

• Processor Capabilities: The T480 utilizes 8th Gen Intel 'Kaby Lake Refresh' processors, while the T490s features slightly newer 8th Gen Intel 'Whiskey Lake' processors. While both offer solid performance for multitasking, web browsing, and office applications, the 'Whiskey Lake' chips in the T490s provide marginal efficiency improvements and slightly higher clock speeds, which can translate to a minor boost in responsiveness for intensive workloads. [1, 4, 11, 15, 25]
• Memory and Storage: The T480 offers two RAM slots, allowing for significant memory expansion up to 64GB, which is beneficial for users running numerous applications simultaneously or working with large datasets. [13, 30, 35] The T490s, with its soldered RAM (up to 32GB), is less flexible for future memory upgrades. [4, 11] Both support fast NVMe SSD storage, ensuring quick boot times and rapid application loading. [4, 6, 13]
• Graphics Performance: The T480 had configurations available with an optional NVIDIA GeForce MX150 discrete graphics card, offering a performance advantage for light graphical tasks, photo editing, or casual gaming. [10, 13, 23, 29] The T490s relies solely on integrated Intel UHD Graphics 620, which is sufficient for everyday visual tasks but not designed for graphically intensive applications. [1, 4, 11, 19]

The visual experience on these laptops varies depending on the specific display panel chosen, with the T490s generally offering more advanced options for clarity and brightness.

• Display Technology and Resolution: Both models offer 14-inch displays with various resolution options, including Full HD (1920x1080) IPS panels. The T480 also had a lower-resolution HD (1366x768) TN panel option, which provides a less vibrant viewing experience. [13, 41] The T490s, however, introduced more premium options, including a WQHD (2560x1440) HDR display with Dolby Vision and a high brightness of 500 nits, as well as a Low Power Full HD panel at 400 nits, offering superior visual fidelity and outdoor visibility. [1, 4, 6, 19, 21]
• Brightness and Clarity: While the T480's Full HD IPS panels offer decent clarity, some users found the base options to be less bright. [2, 17, 32] The T490s, particularly with its higher-end display configurations, provides significantly brighter screens, which improves usability in well-lit environments and enhances media consumption. [1, 4, 19]
• Special Features: The T490s also offered an optional PrivacyGuard display, which limits viewing angles to protect sensitive on-screen information from onlookers, a feature not available on the T480. [4, 19]

For communication and multimedia, both laptops provide standard features, with some minor distinctions in their integrated components.

• Webcam Quality: Both the ThinkPad T480 and T490s typically come equipped with a 720p webcam. This resolution is standard for video conferencing and provides adequate image quality for most virtual meetings. [2, 10, 23, 33, 41]
• Microphone and Speakers: Both models feature dual-array microphones designed to capture clear audio during calls. The T480 includes 2W stereo speakers with Dolby Audio Premium, while the T490s has 1W speakers with Dolby Audio Premium. While both offer satisfactory audio for general use, the T480's slightly more powerful speakers might provide a fuller sound experience. [6, 13]
• Privacy Features: The T490s generally includes a ThinkShutter, a physical privacy cover for the webcam, offering an added layer of security. [6, 9, 11, 14] While some T480 configurations also offered a ThinkShutter or an IR camera for facial recognition, it was not universally present across all models. [10, 23]
