Laptop power consumption is 117 watts but the power adapter is 90 watts what the situation?
Power adapter maximum output power of only 90W, then the machine's power consumption can not exceed this value, the hardware mark prevail, the software is not measured out of this, but according to the various models of hardware projections, for reference only Only, there is no practical significance.
How can the general notebook so high power, do not know how your power is measured out? For the notebook power supply, and then boot power is the highest, usually 60W or so. At this time the power supply size, the actual reflected in the charging speed.
The single is the highest instantaneous power, the overall work will not be in the highest power on the time
Although the adapter voltage is low but the current is large, the notebook motherboard with a voltage regulator, the power supply system through the voltage adjustment to the appropriate pressure for the notebook!
Laptop power consumption is 117 watts generally refers to the maximum power consumption, this is only all the hardware settings at the same time when the power consumption, but in fact all the settings at the same time to achieve the maximum is unlikely, generally 60-80% Is the actual use of the maximum value, the manufacturers are often repeated under the test to determine the power adapter power, is to ensure that the normal work of the laptop (usually about 20% margin) set the capacity, so large Do not have to be tangled for this. Now the power adapter power is rated power, the general instantaneous reach of the power will be more than +20%, but also to meet the normal needs of normal work.
