Does it seem like no matter what you do, your computer is always out of battery power? It might be time to replace the battery. Every battery has a designed capacity-basically the amount of charge that it's designed to hold. Over time batteries lose their ability to hold a charge. This means that even though you're fully charging your battery, the actual amount of power that the battery can hold is going down.

Some of the telltale signs that your battery is going bad are shorter use times, and subsequently, shorter times to recharge. If you notice the amount of time you can spend unplugged is going down, then chances are your battery has lost much of its ability to hold a charge. Another sign that your battery might be on the wane is that it takes less time to recharge. A battery that's going bad might also cause your computer to turn off or hibernate unexpectedly, even if the battery meter displays ample capacity remaining (70 or 80 percent).

Fortunately, Windows can help you know when your battery is unable to hold a full charge. When your battery gets down to 40 percent of its original capacity (that is, it can only hold 40 percent or less of its designed capacity after it has been charged), you'll see a notification via the battery meter icon that your battery might be going bad. This notification is new in Windows 7-earlier versions of Windows can't notify you when your battery is going bad. If you don't want to receive this notification, you can turn it off by clearing the check box on the battery meter.

Many batteries will show signs of problems well before reaching 40 percent of their original capacity. Also, many computer manufacturers have programs that you can use to measure the performance of your battery. These programs might be more sensitive to battery problems and should be used first to check the condition of your computer's battery. For more information about solutions to this problem, see Solutions to common battery problems.

Note

Some computer manufacturers report the designed capacity of their batteries to be the level of the last full charge, so it's possible that your battery might be below the warning threshold without giving you any warning. If your computer continues to run out of battery too quickly, but your battery meter shows that it's fully charging, it might be time to consider replacing your battery. Check with your computer manufacturer for information about replacing your battery.

Using the battery meter to monitor power consumption

• The battery meter is a handy tool located in the notification area of the Windows taskbar that makes it easy for you to keep an eye your computer's power consumption. The battery meter icon indicates whether your laptop is plugged in or whether it's running on battery power . When you point to the battery meter, you can see the percentage of battery charge remaining as well as an estimate of how much time you have until you'll need to plug your computer in.
• When you click the battery meter icon, you can get more information-like which power plan you're using and, if you have more than one battery, how much charge is left in your second battery. You can also change power plans and access additional settings for managing more power options. For more information, see Battery meter: frequently asked questions.

Using power plans to save your battery

One of the easiest ways to save your battery without affecting the performance of your computer is to use one of the built-in power plans that come with Windows. Power plans are basically collections of hardware and software settings that control how your computer uses power. There are two power plans that come with Windows that are useful for laptops:

Balanced. This is the plan that most laptops use by default. It offers full performance and display brightness when you need it and saves power during periods of inactivity.
Power saver. This plan can help you get the most from a single battery charge. It saves power by reducing system performance and screen brightness.

In addition to the power plans that come with Windows, your computer manufacturer might offer additional plans. You can also create your own power plan, or customize the settings for one of the existing plans. For more information, see Change, create, or delete a power plan (scheme).

Getting the most out of your battery

In addition to using power plans to get the most mileage out of a battery charge, it's also important to take care of your battery to make sure you get the most life out of it.

• Make sure you're following the manufacturer's instructions for charging and maintaining your battery. Only use a charger and power cord supplied by the manufacturer.
• Don't let your battery get too hot (or too cold). A hot battery is a sign of trouble and usually means that your battery isn't working properly. You should stop using it right away. Also, make sure that your battery isn't exposed to extreme temperatures. Batteries are designed to work best at room temperatures. Avoid using (or even storing) batteries in extreme temperature conditions.
• Use your battery to keep it fresh. Don't keep your computer plugged in all the time. It's a good idea to discharge and then recharge your laptop battery about once a month. Also, you should let your battery run down before you recharge it.

Telecom Power Energy

Telecom Power Energy

Communication power supply energy, though not of primary energy and energy-saving air-conditioning equipment, can significantly reduce energy consumption room, but the communication power supply room energy consumption as a part of their work not only need to reduce their power consumption, but also need to develop energy saving technology with the main equipment, maximizing reduces room energy consumption.

"Our main equipment annual increase of 15%, but electricity has been no change in the budget, or less than 50 million yuan every year." Complaints director of a land Fangyun Wei, points to the voice communication maintenance personnel.

Today, in charge of not only bears Fangyun Wei basic equipment maintenance, but also the financial cost control, part-time work - the protection of secure communication based on minimizing the operation and maintenance costs. Among them, operation and maintenance costs account for the largest proportion of electricity as an entry point to reduce costs through energy from the main equipment, air-conditioning energy consumption in various angles in-depth analysis, and strive to choose the best investment returns than the energy-saving products and programs, but in the face saving 30%, 50% of the master energy-saving products, good housekeeping operation and maintenance charge of not ignoring the power supply and other ancillary products for communications requirements of energy-saving technologies.

Profitable energy-saving power supply

For the communications room, the communications class power consumption is mainly switching power supply and UPS (uninterruptible power supply), their main function is to translate into electricity inside the computer room or data center equipment for voltage, filter out pollution and high-frequency interference radio, and play the role of voltage, in addition to UPS also has the power to protect the function room to prevent a sudden power failure affected the normal work of the data center to the detriment of high-precision equipment.

From the works of view, communication power consumption should be close to zero consumption, but a rich years of experience in operation and maintenance supervisor told reporters, as communication power in the work process, resulting in the loss of the electromagnetic conversion, filtering the energy consumption Therefore, the base station and the engine room, the communication power of the average electricity consumption of about 5% of the overall machine room power consumption to 10%, in particular the data center, power consuming a higher proportion of 1:00.

Comparison of main equipment and air conditioning, communications, energy supply is small, so some people think that energy conservation is not necessary to spend too much power in the communications effort. In fact compared to other, more communication power saving can play the advantages of input-output ratio.

ZTE power product line product director WANG Dong-xu his calculations, using energy-saving communication power supply products, enabling communication power saving of about 50% of the electricity to the base station, for example, if one day a power saving 2 to 3 degrees, one year is more than 1,000 degrees, more than 60 million base stations nationwide, is more than 600 million annual saving of electricity. Taken together the results of the power saving is very significant.

Second, different way to other energy-saving, energy-saving power products for the environment does not require, you can apply a large area across the country. Communication power supply unlike the new air system, the external application environment is very limited in the application of the new air system prior to the application environment needs to dust, humidity and other environmental parameters of a series of evaluation.

And comparing the main input devices, communication power supply energy is basically a year to recover costs, and modular power management, ease of expansion and to the power room expansion brought about the demand.

The most crucial is the main equipment with energy-saving technologies need to match the power, to avoid the equipment remaining in the main power supply links in the unprovoked wasteful. Can be said that communication with the power saving function of the effectiveness of icing on the cake.

High efficiency, modular paving the way for future development

Communication power saving technology revolves around communication power efficient, modular, current harmonic pollution control features under way.

Many industry experts have this consensus, "first of all need to focus on saving communication power to choose energy efficient products." Particularly applied to large data centers of large power requirements for higher efficiency. Currently, the industry claims to efficient energy-saving products Henduo, but declared energy efficient are fully loaded case Zaichan Pin, when Dianyuanchanpin Chu Yuban set O'clock, but large-scale Xia Xiang Xiao Shuai. Not conducive to energy conservation. Eaton Powerware power products marketing manager Zhang Xuewen that, UPS's full load efficiency of users, no real meaning, he said, as widespread adoption of parallel redundant systems, UPS design margin generally too large, 80% of the current application UPS with a single set of only 50% of actual or lighter, then a lot lighter and therefore even load half load efficiency, UPS is more meaningful to the users.

For large data centers use the UPS, operators for stability, security, telecommunications and other areas to consider only the choice of efficient UPS products. However, base stations and small data center power supply side, there are many alternative energy technologies, modular management is quite good power saving technology.

As an initial capacity of communication power and UPS design, taking into account the maximum load, battery charge capacity and backup capacity, resulting in actual operation in light load and the load is often ultra-light load conditions, this state, the efficiency of power conversion equipment, often lower, thereby increasing its own losses.

Modular Power Management's objective is to start from the engine room of the overall planning, centralized power supply system from the shift to decentralized power supply. As the concentration of power is difficult to avoid the multi-level power distribution, power supply link the more efficient the greater the loss; and scattered distribution, the nearest distribution, can effectively reduce the power loss.

To this end, ZTE made a "breathing" the concept of power management, by tracking changes in the load control power module of the open and sleep to make the system as the best Xiaoshuai point in the vicinity of the work of the power module of the backup method change from hot backup for the cold backup cold backup and a half, reduce in light load and ultra-light module running under load conditions. For the entire power system, the reduction of electricity use, saving electricity, improve operator TCO.

WANG Dong-xu, said the overall look from the communications room, "breathing" power management only in less than 10% efficiency on an issue, but in terms of power source with, lighter set to enhance the efficiency of 85% to about 92% efficient , power equipment, its energy is close to 50%.

200A power supply base station configured to, for example, the case of the four rectifier 50A composed of long-term work load does not exceed 40A of the work situation, with ZTE, "breathing" power management, power saving can be 3 to 4 degrees per day. The total power saving up to a year more than 1,000 degrees, assuming that price one yuan / kWh, then such a site could save over 1000 yuan a year. To communicate the power of life mostly in the 10 years, that is, the equipment throughout the life cycle, saving costs the equivalent of more than 80% of total equipment. The number of base stations for a single province, 15,000 points, the medium-sized operators provinces, the annual saving of electricity more than 15 million yuan.

In fact, ZTE's "breathing" Power management is a prominent advantage of the power module. By using modular power supply, communication power supply can adjust to meet the needs of the existing machine room equipment, to avoid the occurrence of waste. However, modular technology enables communication failure rate increases, though still within reasonable limits, but for the core network and large data centers, the have to be used with caution.

Hsueh-Wen Chang believes that the development of large-scale power module is an inevitable trend, although not currently used widely, but believed that with the technology, continuously improving the stability of large data centers can use the modular power supply.

Be more diversified power structure

Master energy-saving technology innovation, communication power supply must evolve accordingly. To distribution of the base station, for example, although mobile devices is not widely distributed base station applications, but mobile operators have indeed become more and more attention to it high, annual mobile operators are expanding distributed base station Jicai acounts.

Distributed base station to BBU and RRU separation, loss of the previous antenna amplifier circuit to widening losses, reasonable choice of wire and cable pull distance, then if the power supply is also used in the previous model, it will increase the cable length and layout, which requires in addition to traditional computer room power, should also have no air-conditioned environment can be used for indoor coverage, and direct installation of power supply in the open air outdoor power system.

Currently, China Mobile base stations being without air conditioning test, in addition to the main equipment and some equipment, the need to adapt to high temperatures, the communication power supply is also required to adapt to higher temperatures with the energy saving. Energy supply structure and application environment need to be more diversified needs of different applications to meet the installation, distribution and other various needs.

The old equipment

The old equipment

Cordless phones really make life easier. But beware: Some very old equipment to radio waves, which are banned from next year. Anyone who buys a new phone, you can expect heavy fines of up to 2,000 €. pb994a battery

The difference is in some obscure abbreviations. Are prohibited from January devices to cordless CT1 + standard analog transmission, the CT and get second These devices are likely only in very few households, as was already foreseen in 1998 that these standards are eventually eliminated.

The problem: These phones use certain wavelengths that are reserved in 2009 for phone calls. From then on E-Plus and O2 customers will be calling on these frequencies or surf the mobile Internet. On the freedom when cordless phone must therefore not be waived, but a few € for my current device.

For current cordless phones use the so-called DECT StandardDECT stands for "Digital European cordless telecommunications" and introduced in 1992 called the European standard for digital radio transmission. It connects with cordless phones, the mobile handset with the base station. Advantages of DECT is the high voice quality and privacy, the identification of the handset and base station and subscriber identification. With DECT, up to twelve handsets to be connected to the base. That is secure, and guarantee better quality. Do not panic: In most households, these machines are in use for years. According to Manfred Breul, head of the telecommunications industry association Bitkom, have responded to large manufacturers many years ago and stopped production of the old equipment. pb995a battery

From the Far East were in the aftermath, however, still get a lot of cheap imports into Germany. "It may be true that have been sold this year even the analog standard equipment," he warns. Therefore it is difficult to estimate how many such phones are currently in use.

But how can you find out whether one uses one of the banned phones soon? Here the view helps in the manual. "Should not be available, you can also enter the type name of the phone into an Internet search engine and you'll have the necessary information," advises the expert. These data are usually found on the underside of the base station. If both methods do not lead to a result that also helps a simple test.

Therefore you must be on the phone from the base station to leave. In the disputed equipment breaks the connection does not suddenly, but is overlaid by a higher noise. A modern DECT phone You can tell that it comes at too great a distance to sudden interruptions, the connection quality has previously not abated.

Those who still remains one of the prohibited uses as of January phones must face heavy penalties. To track down the old equipment, drive test car of the Federal Network Agency, through residential areas or go to Display. "The effort to identify the source of interference may be 1000-2000, and € is the user of the phone by the Federal Network Agency is charged." Addition could also be imposed a fine. Mild to the user is likely not to share. "There are already ten years a transition period. At some final time must also be "stressed the expert. lenovo ideapad y450 battery

Cordless phones have become anything but expensive in the supermarket or wholesale electronics there are simple devices from 20 €. Even those who prefer a neat device with voice and sound equipment like something, it must not spend so much more: The testers Connect the journal have been tested at the end of time, some devices out there for under 100 €.

For the winner was crowned with the narrow lead Sinus A 501 of the Deutsche Telekom. The telecom markets the devices under its own name, they are manufactured by Siemens. In addition to the convenient phone number management praised the magazine the integrated answering machine. Only the power system, it was easy deductions have here the testers wanted a little more frugal. In Internteshops the devices are to have from 70 € plus shipping.

Hardly a bad cut from the Panasonic KX-TG8321. Here are enchanted by the elegant design, but also on the equipment, processing, and gave the readings it nothing to criticize. No wonder the Japanese manufacturers can point to many years of experience in the development of cordless phones. Of course the Panasonic device has an integrated answering machine the same. Only when there is power for improvement, according to Connect, the testers wanted a modern switching power supply. The price on the internet search revealed to the KX-TG8321 at a price of 65 € plus shipping.

For the price of the magazine has named Tip the Swiss Avena 758th Ironically, the device now costs more than the competitor to Panasonic and is on par with the telecom model. Such price hikes are not uncommon after testing devices have cut heavily. Advantage of the Swiss model is its economy, it must be an owner to live with a smaller screen than the first and second place. Currently, online retailers require from 70 € for the Avena 758, then to get the shipping costs. compaq presario v2000 battery

With the online purchase can save a lot of money, in part, the potential savings is 30 percent or more compared to the retail price. However, there are hunting for bargains a few things to note, as the news.de-shopping guide explains.
