Laptops are a diverse category of devices, and other more specific terms, such as ultrabooks or netbooks, refer to specialist types of laptop which have been optimized for certain uses. Hardware specifications change vastly between these classifications, forgoing greater and greater degrees of processing power to reduce heat emissions.

     1. Quality Attributes

      Reliability

     laptop users gave their machines high marks for durability, support, and most features aside from “performance for the price.

        Performance

     laptop and portable machines is made using thousands of PerformanceTest benchmark results and is updated daily.

       Security

     • Laptop theft is growing fast, representing a staggering 57% of all stolen information. Putting alaptop security program in place is a must for the education, government, and business community.
     • Computer Security Products offers a range oflaptop security devices including laptop cable locks, notebook security cables, laptop tracking and recovery software, laptop lockdown brackets, portable storage laptop carts, netbook security carts, laptop lockers, and STOP security plates.

     VI.Possible problems

     • Laptop hardware problems usually start with the power connector or power supply. The electrical connection to the motherboard becomes loose and the laptop does not charge. This is when many people feel they need a new laptop.
