How it works
1. The official ENERGY STAR record
Every scored figure comes from the ENERGY STAR Certified Computers V9.0 dataset, linked on the product card. If a figure is not published we show "Not listed" and score it at the category minimum, so an unpublished number never outranks a published one. Official ratings are for the certified configuration shown.
2. Different computer types, the same official fields
Official laptops, official desktop PCs and official all-in-one PCs are each ranked in their own table so official form factor does not dominate the score. All three use official TEC, official sleep power, official short-idle power and official system memory. Multiple official configurations of one model share one page, scored on the official configuration with the lowest official TEC.
3. Match it to the work, then check the listing
A lower official TEC is not automatically the right computer for a 16-inch display, a workstation chassis or a long day off-plug. Official battery capacity, official display size and official processor, when published, help you shortlist. Use the official adapter, keep vents clear, and recycle batteries through a certified program. Then check the price on Amazon. Commissions never change the order.
