Part of the lithium-ion battery charge because the regular short period of time, resulting in cell voltage of each power has been lower than 2.5V, then the internal battery protection circuit will open, the battery would be no way to use. Now use the normal charger is no way to recharge it. Some battery analyzers can be imposed on high-voltage lithium-ion battery moment to re-activate the battery. However, if the voltage is below 1.5V batteries and maintained for some time, so best not to charge this battery, this is very dangerous. To prevent this from happening, we recommend that users not in the lithium-ion
EMACHINES E530 Battery is completely discharged in the case of preservation, but should let the battery has some power, the future is full before using it again.
All personal computers (including a number of other electronic devices) has a battery power conditions to ensure the maintenance of some of the data within the system. Usually the battery is a small, non-rechargeable lithium battery. Such as personal computer BIOS settings, current date and time, Plug and Play devices resource allocation and so forth through the battery to maintain data is not lost. Persistent connections in the host power supply case, the battery can usually use 5-7 years, save the battery alone, then only last about 1-2 years. If this battery is exhausted, it will lead to time and date, BIOS settings, and data loss. Since this is a non-rechargeable batteries, so users need to replace the piece.
Not suitable for the temperature, the internal lithium-ion battery will trigger the reaction of other chemical compounds that we do not want to see, so many positive and negative electrodes for lithium ion batteries with protection of temperature between the membrane or electrolyte additives. In the case of the battery to a certain temperature, the composite membrane electrolyte membrane hole closed or degeneration, increased battery internal resistance until the circuit, the battery will not heat up, make sure battery temperature is normal. And deep charge-discharge lithium-ion battery can increase the actual capacity of it? Experts clearly told me that this is meaningless. They even said that the so-called full charge and discharge using the first three of the "active" in their knowledge of where the two doctors, could not understand what this is necessary. But why so many people of deep charge-discharge capacity after the Battery Information in the label will change it? Will be mentioned later.
Although there is little lithium-ion battery memory effect nickel-cadmium batteries, memory effect is the principle of crystallization, in the lithium battery is almost not produce this reaction. However, lithium-ion battery capacity after repeated charge-discharge will continue to decline, its causes are complex and diverse. Mainly positive and negative changes in the material itself, from the molecular level, the positive and negative electrodes of lithium ion on the hole to accommodate the structure will gradually collapse, clogging; from the chemical point of view, is the passive activity of positive and negative material, there's the other side to form a stable compounds. Cathode material physics will appear gradually falling off, etc., in short, can ultimately reduce the
EMACHINES E443 Battery charging and discharging process of free movement of lithium-ion number.
Over-charging and over-discharge, lithium-ion batteries will cause permanent damage to the positive and negative, from the molecular level, can be intuitively understood, excessive discharge of carbon anode will lead to excessive release of lithium ions and makes it appear lamellar structure collapsed, over- Rechargeable lithium-ion will too hard to go into negative carbon structure, and makes some lithium-ion can no longer be released. This is also why the lithium-ion batteries are usually equipped with charge and discharge control circuit of the reasons.
Manipulation some notebook CPU for mobile use and the average desktop CPU is a big difference, mobile CPU operating frequency is generally not fixed, it will be with the software on the CPU to change the CPU requirements of work frequency, of course, the higher the frequency the more costs of electricity, so try not to run in a notebook CPU requirements for software is relatively high, so that CPU operating frequency can be controlled to some extent, in order to achieve the goal to power.
Third, set the power management
WINDOWS control panel in the power management program can be set, we generally can set it to "Portable / Laptop." I also suggest that you can display the screen saver properties set directly to "black", and the wait time is set to 5 minutes, so that when we do not operate in the notebook for some time, it will direct black state, so to run than Other screen saver to be more energy-efficient.
For some brand-name notebook makers, usually provide more professional power management software, in line with their own laptop to use, they often have some special features: for example SONY dedicated power management application can set the cooling fan speed, You can also turn off do not use the IEEE1394 interface and MEMORY STICK slot, to conserve battery power head to; IBM's power management program can reduce the refresh rate of the LCD screen; and TOSHIBA Toshiba's power management program can directly power shortage Close you specify any one device. Rational use of the software can be more extended notebook usage time.
Fourth, the hard disk.
So like Sony laptop
EMACHINES E442 Battery manufacturers own production, is how to control process management, once a quality problem, who will monitor? Sony has not answered so far, but has repeatedly said, "these batteries in extremely rare circumstances will fail," adding that large quantities of recall "is responsible to the consumer." As for the fire explosion personal injury caused by events such as the user provides and uses Sony battery cells of the brand of the computer makers have so far failed to give "how to be responsible" argument. Founder Director of Public Relations Liuren Gang told reporters, notebook manufacturers are monitoring their own products, not specifically a department to monitor the battery and other products.
