Notebook computer Energy Label Energy Consumption Standard and Labeling Method
Neng-ji-zi No. 11005006180
Amended and announced on July 8, 2021, and become valid on July 1, 2023.
1. The applicable scope, test conditions and methods, energy consumption standard, and notebook computer energy label verification should conform to the following regulations:
(1) Applicable scope:
A notebook computer as defined by the National Standards of the Republic of China (hereafter referred to as CNS) 62623 “Desktop and notebook computers - Measurement of energy consumption” or a notebook computer certified by the relevant competent authority, not including tablet computers with touch-control screen or other substitute input devices.
(2) Energy consumption test conditions and methods:
1. Tested according to the testing procedures and conditions in the CNS 62623 regulations.
2. When the product has a preset start ALPM (as ALPM Note 1), test according to Appendix 1 regulations.
(3) Notebook computer energy label energy consumption standard:
The notebook computer's actual tested typical energy consumption ETEC should be lower than or equal to the maximum typical energy consumption ETEC_MAX.
1. The notebook computer's actual tested typical energy consumption ETEC equation is as follows:
ETEC=8.76 × (0.25 × POFF + 0.35×PSLEEP + 0.10×PLONG_IDLE + 0.30×PSHORT_IDLE)
POFF: Off mode tested average power (W)
PSLEEP: Sleep mode tested average power (W)
PLONG_IDLE: Long-term idle state tested average power (W)
PSHORT_IDLE: Short-term idle state tested average power (W)
When notebook computer is equipped with ALPM and preset to start, PALPM indicates the ALPM's average power. Calculation can use PALPMto replace PLONG_IDLE and PSLEEP.
2. Notebook computer's maximum typical energy consumption ETEC_MAX equation is as follows:
ETEC_MAX= 0.65× (TECBASE+ TECMEMORY+ TECGRAPHICS+ TECSTORAGE+ TECINT_DISPLAY)

(3) The product's tested power use POFF
sound to be round up to the second decimal point. If the product is preset to start ALPM, the PALPM
is round up to the second decimal point. The product's ETEC
value and ETEC_MAX
values are rounded up to the first decimal point.
2. The notebook computer energy label energy consumption marking should be processed according to the following regulations:
(1) The name and address of the label user should be clearly displayed on the product or package.
(2) If the aforementioned entity is an agent, the manufacturer's name and address must be displayed on the product or package.
(3) The product catalog shall have the product's ETEC
Note 1: Alternative Low Power Mode (ALPM): when the computer has been idle for a while and has been automatically or manually put into power-saving mode, the screen should be off. Computer with ALPM must maintain an Internet connection or immediate response to the user interface equipment. The Modern-Standby mode commonly seen in recent years is a type of ALPM. PALPM
shows the average power obtained under ALPM.
Note 2: Obtain the basic allowable power use TECBASE
according to fraction P.
•P= [CPU core number] ×[CPU clock rate (GHz)]; of which, the core number represents the physical core and the clock rate represents the CPU's highest clock rate when reaching thermal design power (TDP); does not include turbo boost clock rate.
Note 3: TECGRAPHICS
: only calculate the first installed discrete GPU, but not covering the automatically switchable GPU; of which:
FB_BW: graphic memory bandwidth (GB/s) = memory effective clock rate (MHz) × buffer memory data bandwidth (bits)/(8×1000).
Note 4: TECSTORAGE
: applicable for two or more internal storage units (HDD/SSD); calculate only once.
: increase given by the high-efficiency display; cumulative increase can be used for multiple screens.
2. High-efficiency display must simultaneously satisfy the following definitions: (1) contrast ratio of more than 60:1 (at least 85? horizontal viewing angle); (2) resolution greater than or equal to 2.3 million pixel; (3) gamut supports 99.0% of RGB.
3. Parameter description:
EP: high-efficiency display allowable value (when not a high-efficiency display, EP=0; for high-efficiency display and the screen diagonal length is (d)<27 inches, the EP=0.3; for high-efficiency display and the screen diagonal length is (d)≧27, the EP=0.75).
R: screen resolution (million pixels).
A: viewable area (square inches).
