The Dell Inspiron 5405 is a laptop designed for general computing tasks, offering a balance of performance, portability, and user-friendly features. It supports various operating systems including Windows 10 Pro, Home, and Home in S mode (all 64-bit versions).
The laptop has a sleek design with dimensions of 16.74 mm (0.66 in.) front height, 17.90 mm (0.70 in.) rear height, 321.30 mm (12.65 in.) width, and 216.20 mm (8.51 in.) depth. Its maximum weight is 1.40 kg (3.09 lb), though this can vary based on configuration.
On the right side, the Inspiron 5405 features a microSD-card slot that supports micro-Secure Digital (mSD), micro-Secure Digital High Capacity (mSDHC), and micro-Secure Digital Extended Capacity (mSDXC) card types. It also includes a USB 3.2 Gen 1 port for connecting peripherals with data transfer speeds up to 5 Gbps, and a headset port for headphones or a headset (headphone and microphone combo).
The left side provides a power-adapter port for charging and powering the computer. A power and battery-status light indicates the power state (solid white for charging, solid amber for low/critical battery, off for fully charged). This light also serves for system diagnostics on some models. An HDMI 1.4b port allows connection to external displays or TVs, providing video and audio output. There's another USB 3.2 Gen 1 port for peripherals, and a versatile USB 3.2 Gen 1 (Type-C) port with Power Delivery/DisplayPort capabilities. This Type-C port supports two-way power supply up to 7.5 W and can connect external displays (requires a separate USB Type-C to DisplayPort adapter). The Dell Adapter USB-C to USB-A 3.0 is shipped with the computer to connect legacy USB 3.0 accessories.
The laptop features a touchpad for mouse pointer control, with distinct left-click and right-click areas. The power button, located on the base, can also integrate an optional fingerprint reader for secure login. Pressing the power button turns on the computer, puts it to sleep, or, if held for 4 seconds, forces a shutdown. Power button behavior can be customized in Windows.
The keyboard is available in standard or backlit versions, with a QWERTY layout. It has 81 keys for United States and Canada, 82 keys for United Kingdom, and 85 keys for Japan.
