N400c specifications

The Compaq N400c is a notable lightweight notebook that was introduced in the early 2000s, targeting mobile professionals and students alike. It features a sleek design that highlights portability while still accommodating essential computing capabilities.

One of the main features of the N400c is its size and weight, making it ideal for users who require a laptop that can easily be carried around. Weighing approximately 4.2 pounds, it boasts a compact form factor that is conducive to both travel and work in tight spaces. The N400c is equipped with a 12.1-inch XGA display, offering a resolution of 1024 x 768 pixels, which provides decent clarity for basic productivity tasks, web browsing, and presentations.

In terms of performance, the N400c typically comes with Intel's Pentium III Mobile processor, operating at speeds of around 1 GHz. This processor is designed to deliver adequate performance for everyday computing tasks such as word processing, spreadsheets, and general internet use. Coupled with a maximum of 512 MB of RAM, the N400c ensures that users can multitask efficiently, although it may struggle with more demanding applications.

The storage options available on the N400c include a standard 20 GB hard drive, which can accommodate the necessary documents, software applications, and media files for most users during its time. Additionally, the notebook features a CD-ROM drive, making it easy to install software or play media from discs.

Connectivity is a significant aspect of the N400c, which includes several ports such as USB 1.1, parallel, serial, and VGA for external display connections. Ethernet support is also provided, along with an optional modem for dial-up internet access. While wireless capabilities were becoming increasingly popular, the N400c had limited options for connectivity in that regard.

Battery life is another important characteristic of the Compaq N400c. It typically features a 6-cell Lithium-ion battery, which offers an average battery life of around 3 to 4 hours, depending on usage patterns and power-saving modes employed.

In summary, the Compaq N400c stands out as a practical choice for users seeking a lightweight, portable laptop with sufficient processing power for general tasks. Its combination of decent performance, connectivity options, and compactness makes it a valued device for its time and an appropriate solution for mobile professionals.
