The ThinkPad E420s represents a good value at its $799 price point. Just be aware it has limited screen options and a non-removable battery.
The ThinkPad E420s is a consumer-oriented ThinkPad with a 1-inch thin chassis, a weight of just 4 pounds, and more than 6 hours of battery life. If that isn’t enough to spark your interest, it has a starting price around $700. Read our full review for all the details.

Starting at $699, our E420s has just two optional extras – the faster Core i5 processor (as opposed to the i3 processor in the base system) and the Professional edition of Windows 7. The E420s comes rather well-equipped for the price though coulduse a longer warranty period; business notebooks typically come with a two- or three-year standard. Of special note in the specifications list is the non-removable battery, 7mm thin Seagate hard drive (most drives are thicker at 9.5mm), light weight and slim dimensions.
Build and Design
The E420s departs from the essential ThinkPad design in a number of ways. For starters, the exterior is simpler and sleeker – there are fewer lines and less buttons. The palm rest and keyboard surround, lid, and bottom of the notebook have a rubber non-slip coating, which feels great and adds a measure of durability. The screen has a large glossy piece of plastic covering it, which Lenovo calls “infinity”. It may look good on a display shelf, but in reality it smudges up easily and worse, has even more reflections than a regular glossy display. The edge of the display is surrounded with reflective plastic, which again looks good but is a chore to maintain.
The E420s has a metal alloy support structure inside the chassis, something it has in common with a ThinkPad. The chassis is extremely solid as a result and does not flex even under strong pressure. The lid however could be stronger; it flexes when twisted by the corners; additionally, the fact that minor ripples appear on the screen when pushed in from behind means it could have better support.
Overall the build quality is impressive; aside from some glossy plastic and a lid that could be stronger, there is little to complain about.
Ports and Features
The E420s has an ample array of ports including HDMI v1.4, a USB/eSATA combo port, and a slot-load DVD burner. The inclusion of a DVD burner is notable given the thinness of the chassis; many notebooks are coming without them these days. The E420s lacks USB 3.0, a docking station port, and an ExpressCard slot. Something strange about this notebook is the lack of status lights; at the very least, a hard drive status light should have been included. All picture descriptions are left to right.
