Lenovo ThinkPad T480 14" Vs Lenovo ThinkPad T490 14"

The Lenovo ThinkPad T480, released in 2018, and the Lenovo ThinkPad T490, launched in 2019, are both 14-inch business-oriented laptops from the renowned ThinkPad T-series. While they share core principles of durability and productivity, the T490 introduced a refreshed design and updated internal components, whereas the T480 is notable for its unique hot-swappable dual-battery system. Both devices operate on the Windows platform.

The ThinkPad T480 was released in 2018, making it one year older than the T490, which debuted in 2019. This difference can influence the duration of official operating system support and driver updates.

• Software Longevity: Both models run Windows, with long-term support dictated by Microsoft. The T490, being newer, may receive driver and security updates for a slightly extended period, potentially offering a longer practical lifespan for future Windows iterations.
• Repairability and Upgradability: ThinkPads are generally designed for repairability. The T480 stands out with its external, hot-swappable battery, making battery replacement straightforward. The T490, while robust, features a single internal battery and some RAM soldered to the motherboard, limiting future memory upgrade options compared to the T480's fully slot-based RAM.
• Build Quality: Both laptops utilize durable materials such as magnesium alloy and glass-fiber reinforced plastic, characteristic of the ThinkPad T-series, ensuring they withstand daily professional use.

When evaluating performance, the primary differences between the T480 and T490 lie in their available processor generations and memory configurations, impacting overall system responsiveness and multitasking capabilities.

• Processing Power: The T480 typically features 8th generation Intel processors, while the T490 offers options for both 8th and 10th generation Intel processors. The 10th generation processors generally provide incremental improvements in processing efficiency and integrated graphics, leading to slightly faster application loading and smoother handling of moderately demanding tasks.
• Multitasking and Memory: The T480 supports up to 32GB of RAM across two slots, offering flexibility for upgrades. The T490 can be configured with up to 48GB of RAM, though typically with 8GB or 16GB soldered to the motherboard and one upgradeable slot. This higher maximum capacity in the T490 can benefit users who frequently run numerous applications simultaneously.
• Storage and Responsiveness: The T480 offered both traditional hard drive and solid-state drive options, whereas the T490 primarily utilizes faster NVMe PCIe solid-state drives. This focus on SSDs in the T490 contributes to quicker boot times, faster application launches, and a more responsive overall user experience.

Both the ThinkPad T480 and T490 feature 14-inch displays, but the T490 introduced some panel advancements and a more modern aesthetic.

• Display Technology and Resolution: Both models offer various 14-inch IPS (In-Plane Switching) panels, including Full HD (1920x1080) and WQHD (2560x1440) resolutions. These options provide clear and vibrant visuals suitable for productivity and media consumption.
• Brightness and Special Features: The T490 introduced additional display options, such as a Low Power Full HD panel for improved battery efficiency, and a PrivacyGuard Full HD panel, which limits viewing angles to protect sensitive on-screen information. While both offer good brightness, the T490's specialized panels cater to specific user needs.
• Design and Viewing Experience: The T490 features noticeably slimmer bezels around the display compared to the T480. This design change gives the T490 a more contemporary appearance and can contribute to a slightly more immersive viewing experience, despite both having the same screen size.

For audio-visual capabilities, both the ThinkPad T480 and T490 provide standard features suitable for business communication, with the T490 offering a minor enhancement in security.

• Webcam Performance: Both laptops typically include a 720p webcam, adequate for video conferencing and online meetings in well-lit environments. The image quality is functional for communication rather than high-fidelity photography or video recording.
• Microphone and Speakers: Both models are equipped with dual array microphones designed to reduce background noise, enhancing clarity during calls. The down-firing stereo speakers on both devices provide clear audio for conference calls, presentations, and casual media playback.
• Security Enhancements: The T490 offers an optional infrared (IR) camera, which enables facial recognition for Windows Hello, providing an additional layer of biometric security. Both models also feature a ThinkShutter, a physical privacy cover for the webcam.
