Key Advantages

The ThinkBook 15 Gen 4 offers powerful CPU options that cater to various professional workloads. Its fast NVMe SSD storage boosts overall system responsiveness and quick file access. The inclusion of modern connectivity standards like Thunderbolt 4 and Wi-Fi 6E ensures future-proof networking and accessory support.

The laptop's display delivers sharp and vivid images with anti-glare technology for comfortable extended use. Enhanced security features like TPM 2.0 and fingerprint sensor provide reliable data protection. The backlit keyboard improves usability in low-light conditions, supporting productivity around the clock. Compact design and lightweight build make the device portable without compromising build quality.

Limitations

While performance is solid, integrated graphics options may not be suitable for intensive gaming or high-end graphics workloads. Battery life, although decent, may deplete quicker under heavy usage or with high refresh rate displays. Some configurations may lack discrete GPU options, limiting creative professionals.

Memory upgradeability can be restricted depending on model variants due to soldered RAM. The 15.6-inch size, while offering larger display area, makes the laptop less compact than smaller ultraportable models. Ports and expansion options may be limited compared to workstation-class laptops, potentially necessitating dongles. The chassis material, while premium, might show fingerprints or smudges easily.
