Win7 pure version of the system laptop battery how to save electricity

The first trick brightness setting
The display screen is also a large power consumer, we can reduce the brightness of it to achieve the purpose of power saving. First, right-click on the desktop, then select the “nVIDIA” or “ATi” control panel from the pop-up menu, and lower the brightness value in the “Brightness” option.
After testing, the editor can save about 3W power consumption after lowering the screen brightness, which is equivalent to reducing the standby function by 14%.

The second trick is to turn off unnecessary peripheral devices.
First, enter the BIOS settings of the notebook (press F2 to enter during startup), and in the Advanced option, turn off some of the peripheral devices that are not available at the conference (Disabled). These devices are: Wireless LAN, mouse, and camera. After turning off these unnecessary devices, the editor found that it can save about 2.2W of power consumption, which is equivalent to a 10% reduction in standby function.

The third trick is to close the CPU core.
Many friends think that turning off the multi-core of the books can also save power. Is this the case? We also did a test, shutting down the three cores and leaving only one job. And surprised! In fact, the stupid power consumption has not decreased much. Turning off the CPU core will only increase the load on the processor (such as 4 people’s live, become a person) and does not reduce functionality.

The above is the tutorial on how to save power in the win7 pure version of the notebook battery. The above method can help you to extend the power supply time of the notebook when you need to use the laptop urgently, saving a total of 24% of power consumption. Of course, the best way is to connect the power supply or prepare an auxiliary battery to prevent power outages, so you won’t be afraid even if the game is played for a long time.

How to choose a power adapter？

There are many models of power adapters. How do you choose a power adapter? There are several principles for replacement.

1. The voltage is the same or similar. The nominal input voltage on your computer is 16V, and the rated output voltage of the following adapter is 20V, which is quite different and cannot be replaced in this way, which may damage the computer.

2. The plugs have the same polarity. The polarity of the symbol on your notebook is negative inside and outside. I can’t really see the polarity of the label on the adapter. You can see if the symbol is not the same as the one on the notebook.

3. The rated output current of the power adapter cannot be less than the rated input current of the computer. The maximum input current marked on your computer is 3.36A, then you should buy the output current greater than or equal to 3.36A when you purchase the power adapter, the bigger the better, but the larger the output current, the higher the rated power, too big. Waste, and very cumbersome, generally slightly larger than the line, leaving some margin.

What if AC adapter shell is broken?

In theory, the circuit can be used without damage. Note that the primary side circuit of the power adapter is not isolated from the mains. It is very dangerous to be exposed. Its heat sink will carry dangerous voltage, so don’t use it before you handle the insulation.

What is the phone most afraid of?

Do you know what the phone is most afraid of? The persecution of nature and your own negligence are the reasons for its shortened life! Here are five phones that are most afraid for your reference.

First fear: wet environmental damage:

Avoid using the phone in a humid environment (seaside/rain) to prevent large amounts of moisture from entering the board to form water spots, short circuits, or oxidation of the metal interface. Because if the charging hole is oxidized, there is a risk of burning when charging. The mobile phone should be used moderately to generate a certain temperature inside, and naturally evaporate the water vapor that is usually accumulated. If the mobile phone is not used for a long time, it needs to be specially protected from moisture. Soaking water: Obviously, what kind of things can still be alive after soaking in water? Sulfur: Avoid using mobile phones in places where sulfur is heavy, so as not to aggravate metal oxidation.

 

Second fear: damage caused by collision:

Basic common sense, mechanical collisions are easily damaged. Squeeze: The mobile phone is forced to oppress, although the damage is not as direct as the crash, but some screens have black spots, most of which are caused by the rupture and rupture of the liquid crystal. Because the pressure on the LCD screen can be quite limited, users should pay attention!

Third fear: damage to the temperature environment:

Mobile phones should be protected from heat exposure. In particular, the high temperature in the car in summer makes it easy for the board or battery to change due to high temperatures, and the screen is easily distorted due to material changes. Temperature difference: The temperature difference generated when the mobile phone enters and exits the air-conditioned room. The moisture generated by the cold air may corrode the circuit board, causing short circuit of the electronic components and affecting the life of the mobile phone!

The fourth fear: damage to the improper use of the battery:

If the original battery is not used, the contact between the phone and the battery is not as good as the original battery. Shake for a long time,
There may be loose joints and prone to momentary power outages.

Charging: Do not turn on the phone while charging, so as to avoid the high temperature of the phone charging the board. The car charger should be plugged in after the car is started, so as to avoid the instantaneous peak current flowing back to the mobile phone when the car is started, causing damage to internal parts. Friends who go abroad often have to bring some spare batteries. Otherwise, they must use the original charger to avoid the voltage difference and hurt the machine. Static electricity: The human body is charged with static electricity. If the disassembly and assembly of the mobile phone is not carried out on a platform that can discharge static electricity, it may cause the electrostatic entrainment to invade the fuselage and cause a short circuit.

Fifth fear: the harm of dust and grease:

The accumulation of dust can also interfere with current conduction between the board contacts. Grease: The long-term veneer of the mobile phone panel, the oil on the face may penetrate into the fuselage, pollute the internal lines, causing damage!

Out of battery,go charging?Oh no, your battery won’t accept!

A lithium battery, strictly speaking, is a lithium-metal or lithium alloy anode material, and a non-aqueous electrolyte solution is a disposable battery. The lithium battery we usually refer to is mainly a lithium-ion battery. It is a rechargeable battery that relies on lithium ions to move between the positive and negative electrodes to work. Lithium-ion batteries use an embedded lithium compound as an electrode material. At present, the main positive electrode materials for lithium ion batteries are: LiCoO2, LiMn2O4, LiNiO2 and LiFePO4.
Rechargeable lithium-ion batteries have a wide range of applications, and the batteries we use on various electronic devices are currently lithium-ion batteries. For example, mobile phones, tablets, laptops, and even electric cars.

The reason why it has such a wide range of applications is due to its superior nature. Taken together, it has high energy density, high average output voltage, low self-discharge, no memory effect, wide operating temperature range, excellent cycle performance, fast charge and discharge, high charging efficiency, large output power and long service life. There are quite a few advantages, such as no toxic or hazardous substances.
Lithium-ion polymer batteries are the most commonly used lithium-ion batteries and are very common on a variety of electronic devices. This lithium polymer is an improvement of ordinary lithium ion batteries. It replaces the liquid organic solvent in ordinary lithium ion batteries with colloidal or solid polymer. It has good safety, does not break out, and can shape various shapes. The battery. Therefore, such lithium polycarbon batteries are used in various handheld electronic devices and pure electric vehicles.

Compared with lithium-ion batteries on ordinary handheld electronic devices, lithium-ion batteries on modern pure electric vehicles have the following advantages:

1. The battery capacity is large. The battery capacity of modern pure electric vehicles is generally very large. For example, Tesla’s Model 3 series has the lowest battery capacity of 50 KWH, which is equivalent to 50 kWh. This large battery capacity is achieved by combining a series of lithium-ion batteries in series and in parallel.

2. The charging time is short. Today’s electric cars generally have a fast charge function. Generally, fast charging can be filled with 80% of electricity in half an hour, and the subsequent 20% takes a long time for security reasons. But this is already very convenient. For example, the domestic battery life of pure electric vehicles is generally around 200KM, 80% of the electricity has been able to drive around 160KM, which is enough for short-distance urban commuting.

3. Long battery life. The lithium polymer battery of a mobile phone or a notebook computer generally has a service life of less than 5 years, and the battery capacity will be seriously degraded after more than 5 years, which cannot meet the demand. However, the five years are short for electric vehicles and cannot meet the demand, because the average vehicle usage time will be more than 10 years. Therefore, the batteries of pure electric vehicles are generally improved lithium-ion batteries, and the service life is generally more than 10 years.

Of course, in addition to the above various advantages, lithium ion batteries also have some disadvantages, for example, intolerance to overdischarge. When overdischarged, excessively embedded lithium ions are fixed in the crystal lattice and cannot be released again, resulting in a shortened life, and deep discharge is more likely to damage the battery.

Therefore, using a low battery can damage the lithium ion battery. Therefore, whether it is a mobile phone, a laptop or an electric car, it should not be charged when the battery runs out. Generally speaking, if there are conditions, it should be charged when the battery has about 40%-50% of the battery. .

In addition, lithium-ion batteries are not tolerant of overcharging. When overcharging, the positive electrode of the battery will be deintercalated with too much lithium ions, and overcharging for a long time may cause the lattice to collapse, thereby irreversibly reducing the capacity of the lithium ion battery.

In short, the emergence of lithium-ion battery technology has accelerated the popularity of electronic devices, such as mobile phones and notebook computers. In addition, the commercialization of pure electric vehicles is also inseparable from the development of lithium-ion battery technology. Lithium-ion batteries with large capacity and fast charge and discharge will definitely drive the development of the pure electric vehicle market.
