Best laptops, ranked on official ENERGY STAR specs
Official ENERGY STAR certified notebook computers, including official two-in-one notebooks, rugged notebooks and mobile workstations, compared on the Computers V9.0 record. We score official Typical Energy Consumption (TEC), official sleep-mode power, official short-idle power and official system memory for the certified configuration shown. Missing official fields are shown as Not listed and score at the category minimum. When more than one official configuration is certified, this page uses the official configuration with the lowest official TEC.

Acer N23H7 (R724T)
Score 9.7/10 · Check price
Why it wins: Official TEC 7.7 kWh, official 64 GB memory. Official ENERGY STAR record lists a TEC of 7.7 kWh.. Official ENERGY STAR record lists sleep-mode power of 0.4 W..
"Not listed" means the official manufacturer specification table we used does not publish that figure. Prices show "Check price" until a retailer feed provides a current price.
A computer and its power adapter or internal power supply are mains-powered electrical devices. Use the official power adapter or a certified replacement, keep vents clear, and do not open an internal power supply. Notebook batteries are typically lithium-ion; do not crush, puncture, or incinerate them, and follow the maker's charging and travel guidance. Recycle batteries and electronics through a certified e-waste program. Official Typical Energy Consumption (TEC) is a certified laboratory annual-energy figure for the configuration shown, not a utility bill we measured. Confirm the current official specification, the installed processor, memory and storage, and the adapter rating with the maker and the retailer before you buy.

Other official certified configurations
The ENERGY STAR record lists 10 official certified configurations under this official model. This page uses the official configuration with the lowest official TEC (13.4 kWh). Other official TEC values listed for this model include 13.4.
Every product here has an official ENERGY STAR product type of Notebook, Two-In-One Notebook, Ruggedized Notebook or Mobile Workstation. Official desktop PCs and official all-in-one (integrated) desktops are ranked in their own tables. Official TEC, official sleep power, official short-idle power and official system memory are still the scored fields.
Official TEC is a certified annual-energy figure, not a bill we measured
TEC on the ENERGY STAR Computers V9.0 record is a certified laboratory estimate of typical annual energy use for the configuration shown. A different official processor, memory or display option can change official TEC. Official battery capacity and official display size, when published, are shown as extra details and are not scored.
What “Not listed” means
If official sleep power is missing from the ENERGY STAR record, the field is Not listed and scores at the category minimum. Official Apple records in this dataset often list 0 watt-hours of battery capacity; we show that official battery field as Not listed rather than treat a published zero as a measured capacity. A few official records list battery figures far above a typical watt-hour range; those official numbers are quoted as a source-data note and are not scored.
Safety
A computer and its power adapter or internal power supply are mains-powered electrical devices. Use the official power adapter or a certified replacement, keep vents clear, and do not open an internal power supply. Notebook batteries are typically lithium-ion; do not crush, puncture, or incinerate them, and follow the maker's charging and travel guidance. Recycle batteries and electronics through a certified e-waste program. Official Typical Energy Consumption (TEC) is a certified laboratory annual-energy figure for the configuration shown, not a utility bill we measured. Confirm the current official specification, the installed processor, memory and storage, and the adapter rating with the maker and the retailer before you buy.
How this ranking is calculated
Score = weighted average of normalised specs, out of 10. Full method
Official TECThe official Typical Energy Consumption (TEC) of the certified configuration, in kWh, published on the ENERGY STAR Computers V9.0 record. Lower official TEC is a lower certified annual-energy figure. It is a laboratory result for the configuration shown, not a utility bill we measured. Official values outside the reference range are clamped at the range ends for scoring only; the official figure is still shown. Scale: 25 → 7 kWh.
35%
Official sleep powerThe official Sleep Mode power published on the ENERGY STAR record, in watts. Lower official sleep power means less certified power while the computer is in sleep. If the field is blank it is shown as Not listed. Official values outside the reference range are clamped for scoring only; the official figure is still shown. Scale: 2 → 0.3 W.
25%
Official short-idle powerThe official Short Idle power published on the ENERGY STAR record, in watts. Lower official short-idle power means less certified power in that idle test state. Official values outside the reference range are clamped for scoring only; the official figure is still shown. Scale: 10 → 3 W.
20%
Official system memoryThe official system memory (RAM) published for the certified configuration on the ENERGY STAR record, in GB. A different official configuration of the same model can list a different official memory figure. Official values above the reference best are clamped at that best for scoring only; the official figure is still shown. Scale: 8 → 64 GB.
No. Rankings use only figures published on the ENERGY STAR Certified Computers V9.0 record, each linked on the product page. We do not publish prices, customer ratings or hands-on performance test scores.
Why does a model show only one official memory or processor figure?
ENERGY STAR can certify more than one configuration of the same official model. When that happens we keep one page and score the official configuration with the lowest official TEC. Other official certified configurations, and their official TEC values, are listed as extra details. Confirm the installed processor, memory and storage with the maker and the retailer.
Is a lower official TEC always the right laptop?
No. Official TEC is a certified annual-energy figure for one configuration. It does not tell you whether the official display size, official battery capacity or official processor is the right fit. Use the score to shortlist, then confirm the current official specification with the maker.
Do commissions change the ranking?
