why laptop battery suddenly stop discharging

why laptop battery suddenly stop discharging

Maybe we all face this situation : Some times we should travel to some place as the business or holiday. You know the 12 hours or more journey time is too wearily. So we like enjoy ourself with our laptop to watch movie or play game. Suddenlly the Dell Latitude D620 Battery stop dischargging in the 70% power state or more. You maybe very confuse about this : maybe some problem with my laptop or my laptop dead. In fact most of them are caused by the temperature or the over-Current.

Most laptop batteries have the protection circuit. When the laptop battery temperature is too high or discharge current is too large, out of laptop battery protection circuit action standards. Thus causing the Dell Latitude D600 Battery power automatically stop discharging and force the issue.

The most common situation is that laptop battery is running at full speed . The Dell Inspiron 710m Battery current is too large to result in automatic protection. For example, from the drive to capture the contents of DVD discs into the mobile hard disk, when a large number of both host and peripheral power consumption, is likely to make current standards of protection beyond the battery. D0 not panic in that case. You only used to disconnect peripherals and wait about 10 minutes, then you can reboot the machine.

There is also a common situation : using the battery in a hot environment and high-load operation, , so that the ambient temperature plus the heat generated by the battery self-discharge Dell Inspiron 640m Battery protection circuit may exceed the preset temperature, which is particularly high frequency P4 machines in high-temperature environment may occur after high-speed operation.

Encountered such a situation should remove the batteries placed in a cooler place (remember not to put refrigerator frozen!), After half an hour should be back to normal. High temperature for the lithium Dell TC030 Dell PC764 battery damage is relatively large, less than a last resort and should be avoided in high-temperature environment and high-load operation.

How to charge your laptop battery properly?

How to charge your laptop battery properly?

During the the process of notebook using, we need no to deliberately charge the laptop battery to 100% state or fully discharged laptop battery to automatic shutdown protecting. The correct way is that charge the battery in 20% state and stop charging in 98% . If the machine has the power calibration procedure, when the battery standard-by time significantly reduced. Then calibrate the battery in time to active the protection circuit performance.

For early notebook batteries as Dell XPS M1730 Battery (Ni-MH Ni-MH or Ni-Cd Ni-Cd), really need to fully charge and discharge in order to maintain good battery capacity. But for the lithium battery is not necessary even it may damage the battery.

In fact the lithium batteries has a little memory effect. The lithium VGP-BPS9/S battery materials is very sensitive to the conditions as temperature, the use of frequency and so on. The battery will be aging after used for some period time (standby time reduced). The natural wear and tear is an important reason, and inadequate maintenance is another important reason.

A well-designed lithium batteries have a very good protection circuit to prevent excessive charge and discharge.As over-charging and discharging of the Sony VGP-BPS8 battery will be the rapid reduction activity. Under the protection of protection circuit, the user fully charge and discharge the battery several times, in fact, impossible to achieve had "full" level.

Sometimes WINDOWS show that ThinkPad R40 Battery capacity is 20% or more, you can use 30 minutes. But after used 10 minutes or less the machine suddenly automatically shut down. The reason is that the battery has been aging, the battery protection circuit can not monitors the battery real capacity. In the normal battery depletion, the protection circuit original parameters have been unable to properly reflect the actual situation of the battery

So power calibration procedure is to correct the benchmark protection circuit parameters to accurately reflect the actual capacity of the IBM ThinkPad R50 Battery. This correction process will often take two or three complete charge and discharge. As previously mentioned, fully charge and discharge will reduce the battery activity. It is not frequently used, usually once a month.

Where can I buy a NAS?

Tap Price comparison pcwelt.de the concept of a NAS are listed the most important dealers and equipment and their prices. Also very useful are online shops where you can specify exactly which properties you wish devices. Then you'll see the best candidates. In comparison, you should note that most NAS drives are offered without - so you have the cost of the hard drives still expected to do so.

A particular type of device can we not recommend, but we recommend saving to network the two producers Synology and QNAP. The reason: by now, although many manufacturers have jumped on the NAS-train, have produced the earlier network components. Their devices offer but one crucial drawback: The installed software that is updated less often than with Synology or QNAP. The units of the two companies have also cut off test is always very good.

How many disks do I need?

Larger NAS can accommodate four to five hard drives. How many you need depends on two factors: the required storage and data security. If your files when a hard disk failure still be available, you'll need at least two hard disks, because the files must be stored twice. Read more about it in "What a RAID system?".

Hard drive: 3.5 or 2.5?

Hard drives are available in two formats: 3.5 and 2.5 inches. Most NAS use 3.5-inch hard disks, since these offer several advantages: they have more space, are much cheaper and often faster. Currently let to 3.5-inch hard drives up to two terabytes of hard disk drives, the 2.5-inch counterparts, come on up to 500 gigabytes. A NAS with 2.5-inch hard drives is worthwhile only if you often have to carry the device or if you have little space. Because these devices are much smaller and lighter.

Which Hard Drive?

Modern network storage hard drives require a SATA-I/II-Anschluss. In addition, the drive must have the right size, that is, 2.5 or 3.5 inches. Some NAS drives are supported only up to a certain storage capacity. Please consult the website of the manufacturer.

Generally you should look hard at the following: Do they include words such as "Eco-Green", "GP" (Green Power), "LP" (Low Power) or similar, they eat less power than traditional hard disks. This they achieve with a smaller number of turns. As a nice side effect, they are quieter and produce less waste heat, while also addressing the NAS fan is quieter. Since a NAS is the network connection or the processor speed brakes usually, you need fear no big speed loss.

Heading energy efficient work A

The article via: http://www.guide-shopping.org

Heading still pick up a quick e-mail or look up an appointment with a laptop is no problem. When the battery is empty, also uses the best notebook any more. Then good advice is usually expensive. To not so far and the battery lasts longer, it is worthwhile to note a few tips.

Work has already traveling something. Whether at the lake or on the train, just the laptop on and go. Thus, for even during working quickly once take hitzefrei. However long the break lasts not usually move. After more or less short time the battery is empty and thus the office break ends. With a few tricks can extend battery life, however. What are the tricks, click here.

The course for long working on the road already made the purchase. If the notebook as a desktop replacement, that is, with a strong processor and a gamer video card purchased, it should be also be on the desk.

A press photographer who wants to edit his pictures to send on the road, and should, but buy a fast machine, but have also the same one or two spare batteries in luggage.

The equipment of the notebook provides the energy

Kerstin Hausmann, spokeswoman for the German Energy Agency (dena) says: "The technical equipment of a computer has a decisive effect on its power consumption. Depending on which components are installed in desktop PCs can achieve a power consumption of up to 300 watts, average Power-efficient computer-equipped, however, only about one quarter of it. More power always means more consumption - and thus higher costs. " In stand-by mode, the consumption is about half.

When buying a notebook to the fact that a mobile processor is installed. Such processors, switch back to the mobile operating a gear. Although this means a lower speed, but this will also conserving power. You put the device back to the mains, the processor runs at full power.

Simple Tips

For energy-efficient work the way you should first consider the simplest tips. A general rule: Turn off the radio if you do not need a long time. As a long time, has for ten minutes. Work on the road, you should always be aware that you only have a limited power budget while. If it is possible so a few thoughts to paper to make some with paper and pen a few notes, you should do so. Who works long before the computer and think, losing battery capacity.

Display is not too bright

Reduce the screen brightness. Of course, you should be able to work more pleasant. If the laptop is not being used in the beer garden, you can safely turn the brightness by a few candelas per square meter down. This saves a lot of electricity. Depending on the device it is possible with less brightness, good and happy to ten watts of power saving

Instead use mouse

Notebooks with a touch pad that serves as a mouse equipped. He who uses his laptop on the road, should also draw on this pad. A real mouse is an external device and consumes electricity. So better to dispense and use the touchpad.

Stiftung Warentest examined in the January issue 16 navigation devices. Winner is the Falk F12. Only every second device was evaluated when navigating with "good".

DIGITAL: fujifilm battery , fujifilm np-100 battery , fujifilm np-120 battery .

Only one in two of the tested model in the current January-issue 16 navigation gets from the Stiftung Warentest rated "good" when navigating. One reason: Many of the solutions took too long to calculate a route. The good news: Among the "good" rated devices is also one for 94 € - Mio Moov the M305. The winner of the test but it is clear that more than three times as expensive Falk F12.

In particular, the devices from TomTom Manufacturer leave, according to Stiftung Warentest in pathfinding much time. The models by Garmin and NavGear work more slowly.

Big price difference, the test there are at buy any map updates. Here the prices vary between free tickets for up to 90 € for an update. All units except the Mio Moov M305, both for motorists and for pedestrians calculate routes.

Fuel cell development of new energy vehicles

With China's rapid economic development, the automotive industry has become one of China's pillar industries. According to statistics, China's auto output in 2007 reached 8,500,000, up more than 3000 million holdings, the world's third largest auto producer and second largest auto market. At the same time, fuel consumption has reached 80 million tons, accounting for China's total oil demand of 1/4. Today in the increasingly tense energy, develop new energy vehicles imminent. Energy experts, the CPPCC National Committee member Hu Li Ching put the lock in the hydrogen energy vision, the "use of hydrogen as a motor fuel is undoubtedly the best choice."

Fuel cell power generation system is an important way to achieve the application of hydrogen energy

Hydrogen as secondary energy, wide variety of sources, both from an industrial by-product of fossil energy of hydrogen, but also by solar energy, wind energy, tidal energy and other renewable power can not be stable electrolysis of water into hydrogen energy, but also from the gas, natural gas, bio-bacterial decomposition of organic waste agricultural straw and get, more importantly, renewable and reused.

LCD TVs will overcome the crisis in 2010 B

The increased sales thanks to the producers in particular the paragraph North America, Japan and Western Europe. But also in new markets, there is demand for flat-screen devices.

DELL: dell inspiron 8600 battery , dell inspiron 9300 battery , dell inspiron 9400 battery .

"China is a major growth engine for the global market for flat-screen devices. There can grow, the transition from tube TVs to LCD and plasma TVs to the market," said Hisakazu Torii, DisplaySearch by. "Encouragement of the governments both in China and in Japan a positive effect on demand for flat-screen TV. The change from analogue to digital transmission, which will be held in 2010 increase, probably in Western Europe, the demand for digital TVs. In North America, the massive discounts created a strong demand, especially for devices with 19 ¨C or 20-inch screens. "

A price decline of nine percent for all categories of television had brought the manufacturers narrower profit margins and higher demand. For this reason, the income of the Herstelle 2009, according to DisplaySearch by about ten percent of 112 billion dollars (78 billion euro) fall to 101 billion dollars (70 billion euros). 2010 the price reductions were not as strong. The higher consumer demand, the industry will therefore reward you with higher sales.

PV industry: the bubble has not burst divided the breakthrough

Global production of solar cells last year for the 3436MW, up 56%, of which China accounted for 35% of the share. Global thin film solar cell production reached 400MW, an increase of 1.1 times. According to some foreign authorities to forecast the next three years, the global capacity of PV systems add about 40% annual growth.

Most of our domestic manufacturers by the long single lock, scale expansion, reducing wafer thickness, increase silicon efficiency and conversion efficiency of solar cells and other means to achieve a profitable level of stability. 7 4 quarter alone last year the average gross margin and net margin level of 22.38% and 14.52%, higher than last year's level. Another contradiction between supply and demand by the international market impact of the global supply of polysilicon feedstock extremely nervous prices soared, the spot market price has now risen to 400 U.S. dollars / kg.

Downstream cells are currently a number of domestic companies have investment in the upstream production of polysilicon, some international companies have also announced large-scale capacity expansion plans. General polysilicon construction period 1.5 years -2, the total capacity needed up to 1 year or so, it is expected that the supply of polysilicon feedstock in 2008 is still tight.
