The new ThinkPad T420 has a collection of improvements that end users and IT will appreciate including enhanced video chat and conference calling thanks to a new Conference Call Mode which listens to sounds in a complete 360 degree radius using the dual array microphones and the ability to dial it in with the Private Chat Mode. Users will also love that the keyboard noise is now suppressed so that they can take notes without deafening the other callers.

The ThinkPad T420 also gets a performance boost thanks to TurboBoost+ from Lenovo which makes use of efficient designs and enhancements on the standard Intel TurboBoost 2.0 to keep laptops in TurboBoost for longer so that users have extra power when they need it.

Also updated are several usability features including the ability to close your laptop and walk to another conference room without losing your WiFi connection. IT managers will like that the battery and docking solutions for the Lenovo ThinkPad T, L and W Series are all the same for easy use across the corporation.

The ThinkPad T420 is rated for 15 hours with the standard 9 cell battery, and can be extended to 30 hours using the T series slice battery which stacks on the bottom. Slice batteries add weight, but they don’t extend out the back of the notebook like many extended consumer batteries do.

Its disassembly method is very simple, just like the ThinkPad T470, you only need to remove the external battery first, and then remove all the screws on the bottom case. Use the guitar pick open the bottom case slowly, and there are many snaps on the back cover to securing the case to the laptop body. Be careful do not to break the snaps.

Thinkpad T420 Memory Slots

I’m falling back to options for the T480 because of this year’s disaster of a design T490.

On Lenovo web site, I see T480 with two separate drive slots
1. traditional 2.5″ slot for magnetic hard disk or M.2 2280 SSD.
2. M.2 2242 SSD.

How would I know, if I first buy it with a traditional disk, then replace it later with a M.2 2280 drive, that the adapter cable will be there? Or do I have to source for that cable component separately?
