A core part of all computers (laptops or desktops) is the Central Processing Unit (CPU). In recent years, ARM-based CPUs have become more popular due to their power efficiency which makes them great for mobile devices like smartphones and laptops.

ARM-based CPUs are architecturally different from more traditional x86/x64 CPUs, in which all Sage desktop software applications were created for. 

This means that Sage software, for example Sage 50 Accounts, will not work on a computer which has an ARM based CPU. Some examples of ARM-based CPUs and devices are:

ARM Devices:

• HP OmniBook X
• Lenovo Yoga Slim 7x
• Dell XPS 13
• Microsoft Surface Laptop
• Microsoft Surface Pro 11
• Samsung Galaxy Book 4 Edge
• Acer Swift 14 AI

• ASUS Vivibook S15

ARM CPUs:

• Qualcomm Snapdragon X Elite
• Qualcomm Snapdragon X Plus

 CAUTION: This is not an exhaustive list, more models are available. Please consult with your IT equipment supplier or follow the steps below to check if you have an ARM CPU.
