Unmatched Performance Powered by Intel Core 7 240H

At the heart of the ThinkBook 14 G8 lies the next‑generation Intel Core 7 240H processor, a hybrid CPU architecture offering a powerful combination of Performance (P) and Efficiency (E) cores. According to official specifications, this processor features 14 cores and 20 threads, with boost clock speeds reaching up to 5.1 GHz, delivering cutting‑edge speed for demanding tasks.

This advanced hybrid design intelligently allocates workloads—performance cores handle heavy computing such as video rendering, programming IDEs, virtualization, and multitasking; efficiency cores optimize battery life and handle background tasks. Whether you're running multiple apps, crunching financial models, or handling graphics workflows, the ThinkBook 14 G8 provides sustained, lag‑free responsiveness.

Memory and Storage Designed for Modern Workloads

This model ships with 8GB DDR5-5600MHz RAM, ensuring smooth multitasking for professional and academic use. The memory is partly soldered but includes an additional SODIMM slot, offering expandability up to a massive 64GB, giving professionals the freedom to scale performance as needs grow. 

For storage, the laptop features a 512GB PCIe Gen4 NVMe SSD, offering fast boot speeds, instant app launches, and quick file transfers. The device also includes dual M.2 expansion slots, enabling further storage upgrades for users who manage large datasets, 4K video assets, or multiple virtual machine images. 

This combination of cutting‑edge RAM and blazing fast SSD ensures fluid performance across office suites, cloud collaboration tools, development environments, and creative apps.

Stunning Visuals with a 14‑Inch Full HD IPS Display

The ThinkBook 14 G8 features a 14‑inch Full HD (1920×1080) IPS display, offering vibrant, accurate colors and crisp visuals suitable for everyday productivity, streaming, editing, content review, and online collaboration. The display boasts 300 nits brightness and an anti‑glare coating, ensuring comfortable viewing in bright indoor or outdoor environments.

IPS technology provides wide viewing angles, making it perfect for client presentations, team collaboration, or entertainment. The anti‑glare finish reduces reflections, ideal for users working long hours under office lighting or near windows.

Premium Build Quality with Military‑Grade Durability

Built with a durable aluminum chassis, the ThinkBook 14 G8 is designed to withstand everyday wear while maintaining a premium, professional look. According to verified specifications, the laptop is MIL‑STD‑810H certified, meaning it endures rigorous tests involving shock, dust, temperature, vibration, and accidental handling. 

Weighing around 1.5 kg, it strikes a balance between sturdy construction and portability, making it suitable for travel, office commutes, or hybrid work lifestyles. The modern Arctic Grey finish offers a clean and sophisticated aesthetic, complementing professional work environments.

Advanced Security for Enterprise‑Grade Protection

Business laptops require strong security—and Lenovo delivers. This model includes:

• Fingerprint reader integrated into the power button for secure biometric login 
• TPM 2.0 security chip for hardware‑level encryption
• IR camera support for facial recognition (configuration dependent) 
• Webcam privacy shutter to physically block the camera when not in use

These protections help safeguard sensitive data and maintain privacy in professional environments where cybersecurity is paramount.

Connectivity Without Compromise

The ThinkBook 14 G8 includes an extremely versatile set of ports, allowing you to connect to all essential peripherals without the need for dongles:

From the verified model information:

• 2× Thunderbolt 4 (USB‑C) for high‑speed data transfer and external displays
• 2× USB‑A 3.2 ports
• HDMI 2.1 for 4K external monitors
• RJ‑45 Ethernet for stable wired networking
• SD card reader for creatives
• 3.5mm audio jack
   

Wireless connectivity is equally robust with Wi‑Fi 6E and Bluetooth 5.3, ensuring strong, stable connections during online work, conferencing, and cloud‑based workflows. 

Long‑Lasting Battery with Rapid Charge Capability

According to validated sources, the ThinkBook 14 G8 features a 60Wh battery, offering up to 12 hours of typical use—making it ideal for travel, field work, campus use, or long business days. Rapid Charge technology allows the battery to charge up to 80% in just 1 hour, ensuring you’re ready to continue work quickly. 

This combination of battery efficiency and fast‑charging ensures uninterrupted productivity throughout the day.

Superior User Experience: Keyboard, Audio & Camera

Backlit Keyboard

A backlit keyboard enhances usability in dim or low‑light conditions, allowing comfortable typing during travel or late‑night sessions. 

High‑Quality Audio

The device includes high‑quality speakers and noise‑cancelling microphones suitable for online meetings, webinars, and virtual collaboration sessions. 

1080p FHD Camera with Privacy Shutter

Provides clear, professional video conferencing quality along with essential privacy controls.
