Identifying the make and model of your Windows 7 or Windows 8.1 laptop is usually as simple as finding the logo on top and the model number somewhere on the bottom. To find the model number on some laptops, you have to remove a small plate cover or -- in some cases -- the entire bottom cover. However, if your laptop is entirely unmarked, you can use the Windows Control Panel or the System Information tool to see all the details of your laptop, including specifications.
Finding Information With the Control Panel
Open the Windows 7 Start menu and open the Control Panel.
Select the group of options with the title "System and Security."
Click on the "System" heading. This opens a window that includes several pieces of information. First it lists your version of Windows and whether you have Service Pack 1 installed. Then the model should be listed, though in some cases, this field may be missing. It also lists some of the most important information for determining your laptop's compatibility with software or drivers, including: type of processor, amount of RAM and whether you have a 32-bit or 64-bit system.
