Take you a comprehensive understanding of notebook power and battery

Generally we will care about how big the sound of the notebook fan, how slow the system is running, but it is easy to ignore the power supply or battery, for notebook power and battery How much do you know?

1. In order to prevent the memory effect, do you need to charge the battery before using it?

A: It is unnecessary to discharge the battery before each charge, and it is harmful. . Because the practice proves that the deep discharge of the battery will unnecessarily shorten the battery life, it is recommended that the battery can be charged when it is used about 10%. Of course, when there is still more than 30% of the battery power, it is best not to charge, because the memory effect does exist.

2, the first use of the battery, the first three need to charge 12 hours

A: This is completely unnecessary. Because today's laptops have a complete power management circuit and charging management system, when the battery reaches saturation, the control circuit will automatically switch to the open circuit state, so as long as it is full, it does not mean that the longer you charge, the longer you can use it. of.

3, when inserting AC power, should take the battery down to prevent repeated charging and discharging?

1, even if the battery "unfortunately" is recharged, the loss is not It will be much larger than the power drop caused by not using the battery for a long time.

2, your data is much more precious than your battery or even your notebook. Sudden power outage not only hurts your notebook, but the data that cannot be recovered is too late to regret.

3, the notebook's power control circuit is designed with this feature: when the battery reaches 90% (such as most HP models) or 95% will be charged, and through natural discharge to achieve this capacity The time is from 2 weeks to a month. When the battery is idle for a month or so, it needs to be fully charged and discharged to maintain the battery capacity. At this time, you should be concerned that the battery should be exercised instead of being recharged after being idle.

4, how to extend the notebook's use time as much as possible?

Answer: 1. Use the hard drive and CD-ROM slowdown software: such as NERO DriveSpeed, PowerBooster and other software can be reduced The speed of the drive such as the optical drive and the hard disk can also effectively reduce the work of the notebook.

2. The screen brightness is lowered. The LCD screen is a large power consumer, and the brightness reduction can effectively extend the use time.

3. Turn on the power saving functions such as SpeedStep and PowerPlay. Today's notebook processors and display chips have the ability to reduce operating frequency and voltage to extend the use of time, open the appropriate options can greatly extend battery life.

5. Do you need to fully charge the battery for long-term storage? (The percentage is the percentage of the current saturated state relative to the initial value)

Answer: Storage temperature 40% charge state 100% charge state 0 degree 98 % (after one year) 94% (after one year) 25 degrees 96% (after one year) 80% (after one year) 40 degrees 85% (after one year) 65% (after one year) 60 degrees 75% ( One year later) 60% (after 3 months)

Obviously, if you want to store the battery for a long time, it is best to put it in a dry and low temperature environment and let the remaining battery power be around 40%. Of course, it is best to take the battery out once a month to ensure that the battery is well preserved, and that the battery is completely lost and the battery is damaged.

Power or battery also has a certain role and status in the notebook, so do not ignore it when you usually maintain the computer, you can do it according to the above maintenance, so the life of the notebook or power supply will long.
