Welcome to a laptop battery specialist
of the IBM Laptop Battery
Toshiba's Portégé Z20t is an ultraportable laptop/tablet hybrid, one of the new breed of two-in-one systems that can be used as a slate-mode tablet or a conventional laptop.
It is also one of the early systems based on Intel's Core M platform, designed to offer increased battery life in portable systems without sacrificing performance.
Announced towards the end of last year and shipping since this spring, the Portégé Z20t is aimed at business users and professionals, a traditional market for Toshiba.
In keeping with this, the system looks smart and stylish with battery such as IBM 08K8198 Battery, IBM 08K8197 Battery, IBM 92P1075 Battery, IBM ThinkPad R40 Battery, IBM ThinkPad R32 Battery, IBM 02K6928 Battery, IBM 02K7054 Battery, IBM ThinkPad A20 Battery, IBM ThinkPad A20M Battery, IBM ThinkPad A21M Battery, IBM ThinkPad 240 battery, IBM ThinkPad 240Z battery, but also feels rugged enough to stand up to the rigours of life on the road.
For the mobile professional, the Portégé Z20t offers enough performance for business applications, and at 1.51kg, should not be too weighty to carry around.
A key feature is that the tablet and keyboard sections both have batteries, which Toshiba claims should deliver up to 16 hours of use.
In fact, the Portégé Z20t seems to be one of the most successful two-in-one designs we have seen, so those looking for a mobile business PC that blends the capabilities of a tablet and an ultraportable laptop without too many compromises should add this to their shortlist.
However, potential buyers should be aware that there are several models of the Portégé Z20t, some of which feature Intel's vPro management and security technologies, while others (such as our review unit) do not.
Some also come with a Wacom digitiser screen and stylus while others do not, and some with 3G/4G mobile broadband, while this model did not.
