The Lenovo ThinkBook 15 G4 ABA has a physical footprint of 357 mm wide by 235 mm deep, with a thickness of just 18 mm and a total volume of 1510.11 cm³. It weighs 1700 g, which is fairly typical for a 15.6-inch laptop in this class. The design does not rely on a fanless cooling approach, and it is not weather-sealed or splashproof. On a more practical note, the keyboard includes backlighting, adding usability in lower-light conditions.
The ThinkBook 15 G4 ABA features a 15.6-inch IPS panel with a 1920 x 1080 resolution, resulting in a pixel density of 141 ppi. Typical brightness is rated at 300 nits, and the screen includes an anti-reflection coating to help reduce glare in brighter environments. The display does not support touch input.
The ThinkBook 15 G4 ABA is powered by an eight-core, 64-bit processor built on a 7 nm process, running at a base speed of 2 GHz across all cores and capable of reaching a turbo clock speed of 4.5 GHz, with 16 threads available thanks to multithreading support. It comes with 16GB of DDR4 RAM at 3200 MHz, with the system supporting up to 40GB of memory in total. Storage is handled by a 1024GB NVMe SSD connected over PCIe 4.0, offering flash-based storage with no moving parts. On the graphics side, the integrated GPU runs at a base clock of 300 MHz and a turbo of 2000 MHz, with DirectX 12 support rounding out the graphics capabilities.
In Geekbench 6, the ThinkBook 15 G4 ABA scores 1724 in the single-core test and 6424 in the multi-core test, reflecting the processor's per-core capability alongside its overall multi-threaded throughput. PassMark results follow a similar pattern, with a multi-threaded score of 18067 and a single-threaded score of 3046.
The ThinkBook 15 G4 ABA offers a reasonable spread of ports, including one USB 3.2 Gen 2 Type-C port, two USB 3.2 Gen 1 Type-A ports, and a single HDMI 2.1 output for connecting external displays. There are no Thunderbolt 3 or 4 ports, no USB 4 ports, no DisplayPort or mini DisplayPort outputs, and no VGA connector. Wired networking is covered by one RJ45 Ethernet port, while wireless connectivity includes Wi-Fi 6 (802.11ax) with backward compatibility for Wi-Fi 5 and Wi-Fi 4, alongside Bluetooth 5.1. The laptop also features an external memory card slot and supports AirPlay.
The ThinkBook 15 G4 ABA is equipped with a 45 Wh battery. The laptop does not include sleep-and-charge USB ports, nor does it use a MagSafe power adapter.
The ThinkBook 15 G4 ABA includes stereo speakers and a 3.5 mm headset jack for audio, though it does not support Dolby Atmos or an S/PDIF output. A front-facing camera is built in, supported by two microphones, while biometric options are absent — there is no fingerprint scanner and no 3D facial recognition. Voice commands are not supported. The laptop does not come with a stylus, and it lacks motion and location sensors such as a gyroscope, accelerometer, compass, and GPS. An optical disc drive is also not included.
The processor in the ThinkBook 15 G4 ABA is a laptop-class CPU with a clock multiplier of 20, a maximum operating temperature of 95 °C, and a Thermal Design Power (TDP) of 15W. It contains 10,700 million transistors and supports a range of instruction sets including SSE 4.1, SSE 4.2, AVX, AES, FMA3, F16C, and MMX, along with NX bit support for hardware-level security. The multiplier is locked and the chip does not use big.LITTLE technology. Cache memory is organized across three levels: 512 KB of L1, 4 MB of L2 at 0.5 MB per core, and 16 MB of L3 cache at 2 MB per core. The CPU operates across two memory channels and supports RAM speeds of up to 4267 MHz, though ECC memory is not supported. Integrated graphics come in the form of the Radeon Vega 8 with 8 execution units. The overclocked PassMark result is recorded at 18,850, and compatible chipsets include X570, B550, A520, X470, and B450.
