Lenovo ThinkPad T490 14" Vs Lenovo ThinkPad T490s 14"

The Lenovo ThinkPad T490 and ThinkPad T490s, both 14-inch business laptops released in 2019, offer distinct advantages for different user needs. While they share the core ThinkPad design philosophy of durability and productivity, the T490s prioritizes a more portable form factor, whereas the T490 offers greater internal upgradeability and a wider range of graphics options. Both models run on the Windows operating system, providing a consistent software experience.

Both the ThinkPad T490 and T490s were released in 2019, meaning they have received several years of software updates and are likely to continue receiving critical security patches for a period. The expected practical lifespan for these devices depends heavily on usage patterns and maintenance.

• OS Support Duration: As business-oriented laptops, both models typically receive extended support from Lenovo and Microsoft, ensuring continued compatibility with Windows updates for several years from their release.
• Repairability: The ThinkPad T490 generally offers more flexibility for internal upgrades, particularly with its RAM, which can extend its useful life. The T490s, with its soldered RAM, has limitations in this regard.
• Build Quality: The T490s features an all-metal base unit and a carbon fiber or aluminum lid, contributing to its robust feel. The T490 uses glass fiber plastic with an internal magnesium frame for durability. Both have passed MIL-STD 810G durability testing.

The performance of both the ThinkPad T490 and T490s is well-suited for business and productivity tasks, though there are key differences in their configurations that impact overall responsiveness and multitasking capabilities.

• Processor Capabilities: Both laptops are equipped with 8th or 10th Generation Intel Core processors, providing ample power for demanding applications and smooth multitasking.
• RAM Configuration: The T490 typically comes with some RAM soldered to the motherboard and an additional SO-DIMM slot, allowing for user upgrades up to 40GB or 48GB. In contrast, the T490s has all its RAM soldered, with configurations up to 32GB, meaning no post-purchase memory upgrades are possible.
• Graphics Performance: The T490 offers an optional NVIDIA GeForce MX250 discrete graphics processing unit, which provides enhanced performance for tasks requiring more graphical power. The T490s relies solely on integrated Intel UHD Graphics 620, suitable for general use but not for graphically intensive applications.

Both ThinkPad models offer a range of 14-inch display options, catering to various preferences for visual clarity, brightness, and power efficiency.

• Display Technology and Resolution: Both the T490 and T490s offer Full HD (1920x1080) IPS anti-glare panels. Higher-end configurations for both include WQHD (2560x1440) IPS glossy displays with Dolby Vision HDR, providing vibrant colors and deep blacks.
• Brightness Levels: Screen brightness options vary, with some panels reaching up to 400 nits for improved visibility in bright environments, and the WQHD options on both models capable of 500 nits. Low-power FHD panels are also available for extended battery life.
• Special Features: Both models can be configured with a PrivacyGuard screen option, which limits viewing angles to protect sensitive information from onlookers.

The audio and visual components of both the ThinkPad T490 and T490s are designed to support professional communication and media consumption, with standard features for business use.

• Webcam Quality: Both laptops typically feature a 720p HD webcam, often accompanied by a physical ThinkShutter for privacy. Some configurations may include an optional IR camera for facial recognition.
• Microphone and Speakers: Both models are equipped with dual-array far-field microphones for clear audio input during calls and recordings. They also feature stereo speakers with Dolby Audio Premium for media playback, though user reviews suggest speaker output is generally adequate for business use rather than high-fidelity audio.
• Video Recording: The integrated graphics on both devices support standard video recording quality suitable for virtual meetings and basic content creation. The T490's optional discrete GPU could offer a slight edge in handling more complex video processing tasks.
