Lenovo IdeaPad U400 Ultrabook

The Lenovo IdeaPad U400 is a 14-inch Ultrabook designed for mobile professionals who value a full aluminium chassis and integrated optical drive. It runs Windows 8 Pro on an Intel Core i5-2450M processor with 6GB of DDR3 memory and a 500GB hard drive. Discrete AMD Radeon HD 6470M graphics supplement the integrated Intel HD Graphics 3000 for visual tasks.

Suited for aluminium build and optical media

This laptop suits buyers who want a slim metal body under five pounds with a built-in slot-in DVD reader/writer for discs. The 1366x768 non-touch display and 6GB memory limit users who need higher resolution screens or more RAM for heavy multitasking. Buyers requiring solid-state storage speed or a lighter sub-4lb device should look elsewhere.

Discrete AMD Radeon HD 6470M graphics

The dedicated AMD Radeon HD 6470M GPU provides discrete video memory for better graphics performance than integrated-only alternatives. This specification decides suitability for light creative work or older titles needing discrete acceleration. Verify that this graphics level meets your specific application requirements before purchase.

Questions about this item

Will the 500GB hard drive or the 6GB DDR3 memory need replacing first?

The mechanical 500GB drive is the component most likely to wear out before the soldered 6GB DDR3 memory.

What thermal limit appears first during prolonged loads on the Core i5-2450M and Radeon HD6470M?

The CPU and discrete GPU share a thin ultrabook cooler, so temperature throttling typically arrives before sustained clock speeds can hold.

How loud and hot does the U400 get when running all day?

The aluminium chassis spreads warmth evenly, and the single fan stays at a low hum under typical office workloads.
