From Laptop Repair - Self Help Materials
There's very little difference between troubleshooting a Dell Latitude, Toshiba Satellite, Sony Vaio, IBM Thinkpad, HP Pavilion. The basic structure of all laptops are same, even if one model uses an Intel CPU, another an AMD,a third a PowerPC and a fourth a low power Transmeta. A technician troubleshooting Toshiba laptops may be more like to start with the battery, as they are weak, just as troubleshooting HP and Compaq notebooks often begins with the RAM. IBM and Sony and Apple laptops have been viewed as the good quality than the more popular brands, but they all suffer similar failures due to overheating.
