NEC Personal Computers has released the LAVIE BM94C, a new laptop that prioritizes extreme portability and battery life over raw power. This device matters to travelers and remote workers because it weighs just 999 grams yet claims a two-day runtime without a charger. The company achieved this endurance by using a specialized 99.9 Wh battery built with aerospace-grade carbon laminate from Toray. You should consider this machine if your daily workflow involves moving between locations and you want to leave your power brick at home.
NEC packs a 99.9 Wh battery into a 999 gram laptop chassis
The LAVIE BM94C runs on Intel Core Ultra processors, with options for the Core Ultra 5 (models 322 or 335) or the Core Ultra 7 355. It pairs these chips with up to 32 GB of LPDDR5X memory and an SSD of up to 1 TB. The system features a 14-inch display with a 1920×1200 resolution. NEC designed the internal architecture to support modern connectivity standards while keeping the chassis thin and light.
Specifications
- Battery Capacity: 99.9 Wh
- Weight: 999 g
- Processor Options: Intel Core Ultra 5 322/335 or Ultra 7 355
- Memory: Up to 32 GB LPDDR5X
- Storage: Up to 1 TB SSD
Connectivity options include two Thunderbolt 4 ports, two USB 3.2 Gen 2 ports, HDMI, and Gigabit Ethernet. The laptop also supports Wi-Fi 7 and Bluetooth 5.4 for wireless connections. NEC rates the battery for roughly 30.5 hours of video playback and up to 50.8 hours at idle under JEITA 3.0 testing. A 30-minute fast charge provides enough power for a full eight-hour day of use.
NEC claims the battery retains around 72.7% of its capacity after five years of use. This longevity is managed through an AI charging profile that optimizes power consumption over time. The company states these figures are enough to leave the charger at home for an overnight trip. The LAVIE BM94C is available in Japan starting at 584,100 JPY (around $3,582). It ships in late July.
We looked at other lightweight ultrabooks earlier while tracking NEC's product releases. The LAVIE BM94C stands out by combining a sub-1kg weight with a massive 99.9 Wh cell. This configuration allows users to travel light without sacrificing all-day battery life. The device is now available for purchase in Japan.
