Lenovo IdeaPad U400 Review


The Lenovo IdeaPad U400 is a stylish thin and light laptop. Though not quite and Ultrabook, the U400 exhibits a lot of those features. As Lenovo claims to have a 7hr battery life and a 30 day standby time on the unit. Least take a look at the design of the Lenovo U400. It is made from a single sheet of Aluminum  that is sandblasted to give it a warmer touch.  The U400 is designed to look like a actual note book, though we could agree it borrow a lot of it’s styling from the MacBook. The U400 is less than an inch thick (22.6mm) and weighs about 4.36lbs. Specs wise, the U400 ranges from a 2nd generation Intel core i3- i7, up to 8GB of ram, 1TB of HDD storage or 64GB SSD1 storage, video graphics are either Intel GMA HD 3000 Graphics or AMD Radeon HD6470M 1GB. Built-in DVD drive, 1 USB 3.0, 1 USB 2.0, HDMI out. Integrated 1.3M (720P)webcam.  An interesting part of the U400 is the fact that it has only one vent to keep the unit cool, it  is deigned with a breathable keyboard that allows air to flow through the keyboard into the unit and then two fan cool the system and flush air out the singular vent on the left side of the U400. Here are the specs for the system we tested

  • Intel Core i5 processor 2.4Ghz
  • 6GB of Ram
  • HD6470M 1GB Graphics processor




The Lenovo IdeaPad U400 is a solid Laptop, on the issue and claim of 7hr battery life, I did get roughly 6hrs with Wi-fi , browser on energy efficient mode. Which is close to Lenovo’s stated battery life number. On performance the core i5 processor handled video processing very well and some other heavier task.  Another very useful feature is the Lenovo One Key recovery, which allows you to backup your system easily. Also if you have a failure in Windows you can use the One Key recovery Button on the left side of the U400 to restore your system.  The are some fault with the U400, the most important one is the TouchPad, though nice and smooth, can be finicky, key board feels shallow and no SD card reader slot, which I don’t understand why. Still the Lenovo IdeaPad U400 is a solid Laptop, with great battery life and performance.
