The platform is centered on Windows 7 compatibility, having DDR3 RAM and SATA support with an improved SSDs lineup. However, the laptop still lacks some standard features that have become mass available by that time, such as no DVI/HDMI port on the chassis. This is even less understandable on the 15 inch models. The trackpad is slightly larger than on the previous laptop series. Cooling is clearly improved compared with the previous laptop series but it is much noisier due to the CPU's poor energy efficiency. | The platform is centered on Windows 7 compatibility, having DDR3 RAM and SATA support with an improved SSDs lineup.

The LCD screen continues to be the biggest letdown. As years pass, Lenovo is clearly not bothered to consider screens even a passing importance on this laptop's lineup. The only saving grace is that the screens have the same brightness levels you would expect from other manufacturers and that Lenovo ensured a good enough brightness level range that can be triggered through keyboard shortcuts. | The LCD screen continues to be the biggest letdown.

Also, not redesigning the case after the change from the 16:10 format to 16:9 and specifying the same screen size affects productivity. | ||
It has a high performance CPU, especially compared with the previous if Intel Core 2 Duo offering. The virtual core count is increased from zero to two, helping smoother multitasking. The i7 offering is particularly powerful but the CPUs themselves require lots of cooling making them noisier than the previous T400/T500 range. Higher performing models with NVIDIA graphics are only slightly noisier and warmer than base Intel graphics laptops. | It has a high performance CPU, especially compared with the previous if Intel Core 2 Duo offering.
