Business laptop for mobile professionals

The Dell Latitude 7490 is a 14.0-inch business laptop built for mobile professionals who need reliable productivity on the move. It runs Windows 10 Pro 64-bit on an Intel Core i7-8650U processor with a 2.6GHz base frequency and up to 3.5GHz turbo. The 16GB DDR4 memory and 512GB SSD provide responsive multitasking and fast storage access. A 1920 x 1080 FHD non-touch display, backlit keyboard and integrated HD Graphics 620 complete the package for office work and travel.

Sustained load behaviour and thermal limits

Under sustained load the i7-8650U operates within its ultra-low-power envelope, so clock speeds settle below the 3.5GHz maximum once thermal limits are reached. The integrated HD Graphics 620 shares system memory and is suited to desktop applications rather than heavy 3D or compute tasks. Battery life exceeds 80% of the original capacity, giving several hours of typical office use before a recharge is needed. Fan noise becomes noticeable during prolonged high-CPU workloads such as large compiles or video exports.

Installation experience and common pitfalls

The laptop arrives with Windows 10 Pro pre-installed and configured, so initial setup follows the standard out-of-box experience. Driver updates are delivered through Windows Update and the Dell support site using the 7490 service tag. The 512GB SSD is not user-replaceable without disassembly, and the 16GB DDR4 memory is soldered, preventing future upgrades. Buyers who need more storage or memory should consider a different model. Some units ship with a generic power supply instead of the original Dell adapter.

商品問答

How quiet does the Core i7-8650U run when the laptop is used all day?

The Intel Core i7-8650U operates at a 2.6 GHz base frequency and can boost to 3.5 GHz, allowing efficient performance that keeps fan noise low during extended work sessions.

Which cables and peripherals do I already need to connect to the Type-C, HDMI and RJ-45 ports?

You will need an HDMI cable for external displays, an Ethernet cable for wired networking, and any USB-C accessories such as docks or chargers that match the Type-C port.

Can the HD Graphics 620 drive my older 1920 x 1080 monitor over HDMI?

Yes, the Intel HD Graphics 620 supports the full 1920 x 1080 resolution over the built-in HDMI port, so your existing FHD monitor will work without adapters.
