Lenovo ThinkPad Edge E420s


The Lenovo ThinkPad Edge E420s business laptop is slim, sleek, and loaded with good hardware, but its overall performance is good rather than great.

Speedy processor, hard drive. Light and strong construction. Attractive design. Comfortable keyboard. More affordable than comparable ultraportables. Long battery life. Light on bloatware.

Performance lags behind competitors.

Lenovo ThinkPad E420s Review


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...

Solid build quality ; Excellent keyboard ; Great battery life (6+ hours) ; Good design

Non-removable battery ; Low-resolution display ; No status lights ; 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.

Lenovo ThinkPad Edge E420s Laptop Review


There's a time and place to act a fool, like at a Ludacris concert for example, or when entertaining your in-laws during a holiday function in which you're trying to encourage a hasty departure. Likewise, there are situations where showboating simply...

Chic design with a clean layout ; Quad-core foundation ; Dolby Home Theater v4 audio technology ; HD webcam performs well in low light situations

Lack luster gaming performance ; Difficult access to internal components

Lenovo designed the ThinkPad Edge E420s for small-to-medium business (SMB) users, and if evaluating it on those terms, the E420s proves a solid workhorse. It has plenty of horsepower to beam PowerPoint presentations to potential clients, and with its...

Lenovo ThinkPad Edge E420s review


The Lenovo ThinkPad Edge E420s would never be accused of being pretty, though it is worth noting that the ThinkPad range has come a long way since Lenovo acquired it from IBM. They're still built like tanks, though, and the E420s is built to shrug off...

The ThinkPad E420s couldn’t be much different from the excellent Lenovo IdeaPad G570. To be fair to the ThinkPad it is a very work-focused model, but the poor battery life, lack of storage space, mediocre screen and relatively high price all count...

Lenovo ThinkPad Edge E420s 14in Core i5 laptop


Review I have always been a fan of ThinkPads, ever since my father brought home a beaten 560e featuring a 150MHz Pentium which was rejected from the corporate pool due to travel abuse. Even though half of its 1GB disk was bad sectors I ran it well into...

The ThinkPad range has been typically targeted at business users, however, I can certainly see more general users adopting the Edge series, especially as the price of the business class fare edges further below the £1000 mark. This Core i5 version is...
