Overview

The Lenovo ThinkBook 15 G3 ACL is a business-oriented laptop built around the AMD Ryzen 5 5500U processor, a six-core chip that balances performance and efficiency for everyday productivity tasks. Paired with 20GB of DDR4 RAM — a generous allocation that combines 4GB soldered onboard with a 16GB SO-DIMM — and a 1TB PCIe SSD, this machine handles office applications, web browsing, video conferencing, and moderate multitasking without hesitation. The 15.6-inch Full HD IPS panel provides crisp 1920x1080 resolution with consistent viewing angles, while the grey backlit keyboard supports comfortable typing in any lighting condition.

Connectivity is a strong point for the ThinkBook 15 G3, with two USB 3.2 Type-C Gen2 ports, two USB 3.2 Gen1 Type-A ports, HDMI output, an SD card reader, and a built-in RJ-45 Ethernet jack complementing 802.11ax Wi-Fi 6 and Bluetooth 5.2 wireless. At just 3.75 pounds and 0.75 inches thin in its Mineral Grey chassis, the laptop remains portable enough for commuting and travel. Windows 10 Pro provides enterprise-grade features including BitLocker encryption and remote desktop, with an upgrade path to Windows 11 available. The 65W power supply keeps the 3-cell 45 WHr battery charged, though users who frequently work unplugged may want to keep the charger accessible.

Pros & Cons

👍 Pros

20GB RAM provides ample headroom for multitasking and business applications
1TB PCIe SSD offers fast boot times and generous storage for files and applications
Full array of ports including USB-C, HDMI, Ethernet, and SD card reader eliminates dongle dependency
15.6-inch Full HD IPS display delivers clear visuals with wide viewing angles
Lightweight at 3.75 pounds for a 15-inch business laptop

👎 Cons

45 WHr battery is on the smaller side for a 15.6-inch laptop, limiting unplugged endurance
720p webcam produces lower quality video compared to 1080p cameras on competing models
4GB of RAM is soldered, so total memory expansion depends on the single SO-DIMM slot
Integrated AMD Radeon graphics are not suited for demanding creative or gaming workloads
60Hz display refresh rate is standard but unremarkable compared to higher-refresh options

Frequently Asked Questions

The ThinkBook 15 G3 provides 2 USB 3.2 Gen1 Type-A ports, 2 USB 3.2 Type-C Gen2 ports, 1 HDMI port, an SD card reader, and an RJ-45 Ethernet port.

Does it come with Windows 11 or Windows 10?
