Performance and Benchmarks
Our review unit’s performance is bottlenecked by the amply sized but lethargic 1TB 5400RPM hard drive. Lenovo could have mitigated this by offering an SSD cache or hybrid hard drive/SSD combo. The 1TB drive seems dominant on all Z400 Touch configurations but as I noted earlier in the review, this drive can be upgraded provided you’re willing to disassemble the chassis.
Our Lenovo IdeaPad Z400 Touch review unit has the following specifications:
- 14-inch touch-enabled display (1366×768 resolution, TN panel, glass surface)
- Windows 8
- Intel Core i5-3230M dual-core processor (2.6GHz, up to 3.2GHz Turbo Boost, 3MB cache, 35W TDP)
- Integrated Intel HD graphics
- 6GB DDR3-1333 RAM (1x 2GB, 1x 4GB; max. supported)
- 1TB 5400RPM hard drive
- Internal DVD burner
- Intel Centrino Wireless-N 2230
- Integrated Bluetooth 4.0
- Integrated HD webcam
- 4-cell li-ion battery
- 1-year limited warranty
- Dimensions: 13.6 x 9.6 x 1.14 inches
- Weight: 5.29 lbs.
- Starting price: $599.99
- Price as configured: $719.99
These specifications are slightly better than average due to the inclusion of the touch display though otherwise unremarkable. That isn’t to say they’re inadequate; the Z400’s level of performance regardless of configuration is sufficient for almost every personal computing task minus 3D gaming (such as Call of Duty: Black Ops II) since no dedicated graphics card is offered. For power enthusiasts, Lenovo makes an Intel Core i7 quad-core processor available in the top tier ($800+) Z400 Touch configurations.

Heat and Noise
The Z400’s single fan exhausts out the left side of the chassis. This traditional design is more practical than the increasingly trendy but shortsighted cooling systems on some newer notebooks, where the exhaust is situated at the back of the chassis and deflects air off the display lid. The Z400’s cooling design is more effective since exhaust is ported directly out of the chassis, keeping it and other parts of the notebook overall cooler.
The Z400’s fan remains dormant for most normal activity including light web browsing. It’s inaudible except in a near-silent room on low speeds.
The IdeaPad Z400’s internal battery provided three hours, 11 minutes of runtime; this translates to about five and a half hours of real-life usage which is just shy of Lenovo’s claims. This is an average time for a 14-inch budget notebook.
