What can we say about the design of ThinkPad - these phones have always put function over form. ThinkPads that we know has changed subtly but surely, they were introduced 20 years ago. The L420 has a black plastic exterior with a subtle matte finish. Unlike previous ThinkPad is not in L420,
with its square cut in the sides and front with a gentle slope. An interesting feature is the design of loudspeakers in the cover under the screen, portable speaker for most companies are still in the palm of the hand or on both sides of the keyboard.
Overall build quality is excellent, despite all external plastic, feels solid L420. The plastic is thick and tough. The wrist area barely moves when pressed, which means it is a great support. The frame is folded once twisted the corners, which is another good indicator of a solid internal structure.
Two metal hinges of the screen is well positioned to support the bridge, I am inflexible. Because all the plastic, the screen becomes a bit "in place, and push the screen to cause some ripples on the screen. This should be a non-problem, assuming your laptop is not thrown around. Those who wish to update the L420 easy to find the RAM, hard drive and wireless card, remove the large main panel at the bottom of the laptop.
