Before paying for a update to Windows 8.1 from XP...or even updating from Windows 8 to Windows 8.1 on your laptop...make sure your laptop supports the upgrade. Failure to check could lead to no compatible drivers. This holds true for all laptop brands. Every manufacturer has a "can I update to..." in its support section. Amd says..
"" If the current operating system is not the version originally installed on the notebook it may not meet all requirements and compatible graphics drivers may not be available. Please refer to the notebook manufacturer for supported operating systems and drivers.""
