Lenovo Enhanced Experience 3
Lenovo Enhanced Experience 3 for Windows® 7, our 2012 edition, is both fast and optimized. Using Lenovo's RapidBoot technology, Enhanced Experience 3 PCs have optimized system files, processes, and hardware settings to start your PC 40% faster than a typical Windows® 7 computer (based on tests conducted by CNET Labs, Beijing in December 2011Results take the average of Lenovo EE 3 notebooks and desktops and compare with averaged data from 49 competitor products of similar configuration (Intel® Core™ i3, i5 and i7 PCs only). Testing conducted using the independent VTS tool to measure start-up time and other performance measurements. Note that EE 3 performance times vary by model and configuration.). Plus with our new technology, BootShield continues to maintain fast boot performance even when multiple applications are installed over the life of your system.
How RapidBoot Works
RapidBoot uses a collection of proprietary technologies and optimizations, which vary based on the EE 3 system. Smart defragmentation defragments the area of the hard disk drive that contains the boot files used to load Windows®. Defragmenting increases the speed that the data can be accessed and read. HDD accelerator uses system memory (RAM) as a cache for boot files, which allows faster performance.

At the same time, advanced optimization occurs on several levels. Hundreds of drivers have been reconfigured to improve performance. Proprietary BIOS development reduces BIOS post time. Non-essential Windows® 7 services are delayed until after the boot process is complete. Preinstalled software (like antivirus) is compiled and imaged. And finally, we use only the highest quality for key components like graphics, hard drive, and memory, which drastically increases performance.

Time taken from power-on until boot is complete (defined as CPU no longer being used to load Windows® 7 and start-up applications). A Lenovo Enhanced Experience 3 PC features a fast start-up process while still initializing critical security features like antivirus software.
How BootShield Works
BootShield, which is only available on our notebooks, checks the availability of system resources during the boot process and selectively pauses the launch of additional software until resources are freed up or until the user manually launches the specific program. As a PC ages, more software is typically installed, which if left unchecked, can greatly contribute to decreased system performance and boot. With time, the benefit of BootShield continues to grow.

Optimized for Business
A Lenovo Enhanced Experience 3 PC offers more than just fast boot. EE 3 systems are optimized for business — whether large or small.Not all features are available on all models. Robust security features include self-encrypting drives, fingerprint ID, BIOS port locks, and more. Superior web conferencing functionality incorporates light-adaptive, HD webcams, advanced noise-cancellation technology, and dual digital array microphones.

The Difference Between EE 2.0 and EE 3
EE 2.0 focused on both RapidBoot and RapidDrive technology, with the latter applying only to systems with a solid state drive (SSD). While we continue to improve RapidBoot technology, EE 3 focuses on PCs with standard (i.e., spinning) hard disk drives (HDDs). These PCs are configured with Intel® Core™ i3 or higher and meet the criteria of desktop startup in 23 seconds and laptop startup in 25 seconds. (The average boot time for an EE 2.0 certified PC is 29 seconds.)

Additionally, our laptops that include EE 3 also include BootShield technology, which is exclusive to EE 3. Bootshield maintains fast boot performance even after installing multiple applications. What's more important than the boot times between EE versions, however, is the difference between an EE 3 certified model and an average PC running Windows® 7: the Lenovo Enhanced Experience 3 PC boots 40% faster!

Note: Because EE 3 involves a combination of many optimization technologies and, in some cases, hardware changes, it's not possible to upgrade to EE 3. Even with the latest drivers and BIOS updates, it's still not possible to achieve the same performance standards.

Basis for EE 3 Performance Claims
The claims for EE 3 are based on testing a large number of competitor products that are popularly available in a variety of countries and comparing them against similar Lenovo products. All testing was conducted independently by CNET Labs, Beijing in December 2011, using the independent VTS tool — which is the industry standard measurement tool for PC boot times. The claim of "40% faster" is calculated from taking the midpoint of our Lenovo EE 3 notebooks and desktops, and then comparing that midpoint with averaged data from 49 competitor productsSample competitors include Acer, Apple, Dell, HP, Samsung, Sony, and Toshiba. of similar configuration (Intel® Core™ i3, i5, and i7 PCs only). Performance varies by model and configuration. This measurement may differ from the time taken from pressing the power-on button until the appearance of the Windows® Start menu when measured with a stopwatch.

System Imaging Impact on Corporate Customers
Corporate preload images vary greatly. We optimize the software that's preloaded on a Lenovo system, identifying and correcting any performance bottleneck that occurs. Additionally, we install proprietary technology that further improves boot performance. Using Lenovo-provided BIOS, drivers, and software utilities significantly decreases boot performance issues. Nonetheless, there are three methods that our large enterprise customers can choose from:
  • Build corporate image using the Enhanced Experience 3 preload as a base and realize up to 100% of EE performance benefits.
  • Lenovo builds the corporate image to customer specifications, using Enhanced Experience 3 preload as a base, and customers realize up to 100% of EE performance benefits.
  • Build corporate image without using EE 3 as a preload, but installs the latest BIOS, drivers, and software utilities from Lenovo.com, and realize up to 80% of EE performance benefits.
