Chuwi’s CoreBook series, once praised for its ultra-portable design and affordability, is now at the center of an unexpected technical setback. The company is offering full refunds after discovering a significant thermal management issue with the laptop’s custom CPU variant, which can lead to overheating during prolonged use.
This problem stems from a mismatch between the CoreBook’s cooling system and the power requirements of its proprietary x86-based processor. While Chuwi has built a strong reputation for delivering lightweight laptops without major technical hiccups, this incident marks a notable exception. The flaw affects both the 14-inch and 16-inch models, which were designed to balance portability with everyday computing tasks like browsing, document work, and light media consumption.
- Key specifications:
- Display: 14-inch or 16-inch 2K IPS (1920x1200) with 300 nits brightness
- CPU: Custom x86-based SoC optimized for low-power workloads
- RAM: Up to 16 GB LPDDR5 (soldered, no upgrade path)
- Storage: Up to 1 TB NVMe SSD
- Ports: Two USB-C (one with Thunderbolt 4), microSD slot, 3.5mm audio jack; lacks HDMI or Ethernet
- Weight: 980 grams (14-inch) / 1.1 kilograms (16-inch)
- Price: Originally $799 for the base model, now being fully refunded
The CoreBook’s compact form factor and budget-friendly price made it a standout in the ultraportable market. However, this CPU limitation exposes a trade-off that power users must now consider—convenience versus long-term reliability. For those who demand sustained performance or extended battery life, this flaw could make the CoreBook less appealing compared to competitors like the ASUS Vivobook Flip.
Chuwi is reportedly working on a hardware revision to address the cooling issue, but no timeline has been confirmed. The question remains whether the revised model will retain its original price point or if the CoreBook can regain its footing in a competitive market. For now, affected users are advised to contact Chuwi’s support team for refund processing.
