Both ultra-slim laptops come with the ASUS Turbo33 Technology


Reportedly, the March issue of ASUS eMagazine disclosed two new ultra-portable computers that add to the company’s UL (UnLimited) Series. The UL20At and UL30Jt feature aluminum exterior, less than 1-inch profile, long battery life but do not pack a built-in optical drive.

These notebooks come with the ASUS Turbo33 Technology, which supposedly enhances system performance by up to 33%. Furthermore, the UL30Jt supports NVIDIA’s Optimus Technology.



This Intel GS45 Chipset-sporting thin and light laptop is powered by up to an ultra-low voltage Intel Core 2 Duo SU7300 (45nm) central processing unit with a clock frequency of 1.3GHz, 3MB of cache and a 10W Max TDP.  In addition, it is equipped with a 12.1-inch Glare LED backlit display with a maximum resolution of 1366-by-768 pixels, providing customers with the opportunity to watch and enjoy HD 720p videos.

The ASUS UL20At comes with up to 4GB of internal 1066MHz DDR3 memory and up to a 500GB HDD that rotates at 5400RPM. Graphics are taken care by an Intel GMA 4500MHD, which sports both dedicated and shared video RAM.

In terms of connectivity, this ultra-slim notebook ships with an integrated Wi-Fi 802.11 b/g/n module and a 0.3MP web camera for video conferencing.


This model packs an Intel HM55 Chipset and offers more power in form of a low-voltage 2010 Intel Core processor. Users are provided with up to an Intel Core i7-640UM CPU with a core speed of 1.2GHz (2.26GHz with Turbo Boost Technology), 4MB of cache and 18W Max TDP. Moreover, thanks to the Intel Hyper-Threading Technology, the system remains stable even if multiple applications are being run simultaneously.

The 13.3-inch Glare LCD widescreen display delivers a 1366-by-768 pixels HD resolution. As already mentioned above, the UL30Jt ships with the NVIDIA Optimus Technology, which presumably lets consumers switch between the integrated Intel GMA HD and NVIDIA GeForce 310M (1GB of dedicated DDR3 VRAM) graphics controllers. This feature is useful depending on whether you need longer battery life or high-performance at a particular moment.

The ultra-slim notebook can handle up to 4GB of RAM and has a storage capacity of up to 640GB (HDD, 5400RPM). A 0.3MP web camera is also available for video chats.

Other specs

Both ultra-portable laptops come with up to a Microsoft Windows 7 Ultimate operating system. ASUS claims the UL20At weighs 1.56kg (3.44lbs) with the integrated 6-cell battery, which is good for up to eight hours on single charge. In addition, the UL30Jt reportedly has a battery life of up to ten hours (8-cell battery) and a weight of 1.7kg (3.75lbs).
