How to Choose Compaq Evo N410c battery for your laptop

How to Choose Compaq Evo N410c battery for your laptop

Equally at home on the road or on the desktop, the Evo N410c can serve as a lightweight ultraportable or as a desktop alternative, depending on your needs. It weighs a scant 3.6 pounds without add-ons, but includes a surprisingly full set of connections and wireless connectivity via a Wi-Fi (802.11b) module that mounts on the lid. (A Bluetooth module sells for $129.) An extra battery such as Compaq EVO N400 Battery Compaq EVO N410 Battery can be snapped onto the back. When plunked atop its Mobile Expansion Unit docking station, or MEU, the N410c gains two modular bays that bring a whole raft of additional configuration possibilities. With the MEU attached, you can equip the Compaq EVO N410c Battery with two optical drives at once, or with a total of four batteries for (according to Compaq) up to 10 hours of cord-free computing. The MEU also replicates the notebook's connections, adds two USB 1.1 ports (for a total of four), and provides good stereo speakers.

You might feel nickel-and-dimed trying to get everything you'll need for the N410c. The optical drive and an internal or external floppy drive cost extra ($219 for the 8X DVD-ROM drive we got with our test unit and $69 for the internal floppy drive). The MEU, or docking station, costs another $199 and adds two pounds to the weight. Compaq EVO N400c Battery life with the N410c's standard 4-cell internal power pack is about the same as its predecessor's, the N400c: only two hours. Should you need longer battery life, a second, high-capacity external 4-cell battery adds $219 to the price.

For top longevity, you can buy two additional two-cell batteries such as Compaq EVO N400 battery Compaq EVO N400c battery Compaq EVO N410 battery Compaq EVO N410c battery etc.for the MEU's modular bays at a low price online from http://www.battery-mag.co.uk, apiece for a total of four power packs in use simultaneously. The MEU is easy to pop on and off the notebook using a big blue latch button on the side, but its drives are difficult to eject. You have to slide a release on the bottom, and the devices tend to stick in the bay--our DVD-ROM drive and floppy drive froze halfway, and we had to tug them out. Finally, the hard drive isn't removable by the user.

A modest refresh of last year's EVO N400c Battery, the EVO N410 Battery doesn't include many changes, except for an upward tick in processing speed and a different pointing device, but then it didn't need many improvements. Equipped with the top processor currently available for its size, the 1.2-GHz/800-MHz Pentium III-M, the Evo turned in a terrific PC WorldBench 4 score of 101, better than that of many full-size Pentium 4-M-equipped notebooks we've tested. The keyboard now sports a touchpad instead of an eraserhead and better-positioned mouse buttons: both welcome changes.

With its full stroke and spacing, the EVO N400 Battery line's keyboard has always been easier to type on than those of most other ultraportable notebooks. That hasn't changed with the N410c. Neither has the handy set of four dedicated shortcut buttons and the notebook's crisp 12.1-inch screen. You even get volume buttons on the front of the notebook and a TV-out port on the back (although it has no FireWire port). The MEU adds impressive-sounding speakers for such a small notebook. Overall, Compaq provides attractive, handy, and thorough documentation, including troubleshooting and ergonomic booklets; we only wish that the Acrobat-format manuals on CD-ROM were also provided in easier-to-access print form.

Although the EVO N410c Battery's price is higher than those of some other ultraportables, its docking station's flexibility is unique. All in all, it's a compelling wireless-ready portable, great for the road (and easy to set back up on the desktop).

Tips to maximise laptop battery performance:

• Brightness: how low can you go? Without any question, the fastest way to suck the life out of a laptop battery is leaving your brightness high. Turn it down as low as you possibly can without needing to up your glasses prescription.
• Single-task, not multi-task. The more you are doing at the same time with your PC, the more memory and CPU usage increases. Both of which directly use up hp laptop battery
• Do not let your battery dormant for long periods of time. I recommend using the hp 530 battery at least once every two to three weeks. If a battery has not been used for a long period of time, perform the new battery break in the proceedings described above.
  
• Rechargeable hp 530 battery will give you their longest charge when you've fully discharged and recharged them several times in a row. It may be a pain, but a day or so before your trip, let your laptop run until the system shuts down. Then recharge it and, if you have time, discharge and recharge it a second time, preferably overnight.
• Once your hp 530 laptop battery is full, tweak your laptop's settings to maximize battery life.

The main performance indicators of rechargeable batteries

The main performance indicators of rechargeable batteries

Safety performance indicators for battery failure is unacceptable. In which the greatest impact is the explosion and leakage. The occurrence of explosions and leakage mainly related to the battery internal pressure, structure and process design (such as valve failure to Acer LCBTP03003 Latitude D600 Battery Latitude D610 Battery, there is no lithium-ion battery protection circuit, etc.) and should be prohibited by the incorrect operation (for example, a battery into a fire) of the.
To AA 2300mAh Ni-MH rechargeable batteries, for example, indicates that the batteries 230mA (0.1C) charge 16 hours after 460mA (0.2C) discharge to 1.0V, the total discharge time of 5 hours, the release of electricity for the 2300mAh. Accordingly, if 230mA of current discharge, the discharge time is about 10 hours with 45Wh Apple PowerBook G4 Adapter.

Refers to a certain discharge conditions, the battery can release the total electricity consumption. In accordance with IEC standard and GB, nickel cadmium and nickel-metal hydride batteries in 20 ± 5 ° C conditions, in order to 0.1C to 0.2C charge 16 hours after discharge to the 1.0V power emitted when the Dell Latitude D620 Battery Dell Inspiron 710m Battery Dell Latitude D800 Battery's rated capacity to C expression; Lithium-ion battery at room temperature, constant current (1C), constant-voltage (4.2V) after 3 hours under the condition of charge to 0.2C discharge to 2.75V emitted when the battery's rated capacity of electricity. The unit of mAh battery capacity, and Ah (1Ah = 1000mAh).

Battery internal resistance refers to the current flowing through the Sony VGP-BPS12 battery when the subject of internal resistance. Charging the battery internal resistance is small between ibook g4 adapter and APple A1021 adapter, need to use special equipment can only be measured more accurate results. Generally known as the battery internal resistance is the charge-state resistance, meaning that the battery is fully charged when the resistance (corresponding to a discharge state of resistance, saying that after the battery fully discharge resistance by 65Wh Apple PowerBook G4 Adapter. Generally speaking, the discharge state of resistance Charge-state resistance than the large, and not very stable). The greater the battery internal resistance, the battery itself consumes energy more efficient use of the battery lower.

A great resistance when the battery charge is very severe fever to Sony PCGA-BP2NY battery PCGA-BP51 battery, so that the battery temperature is rising sharply. The impact on the battery and charger are all great. With the increase in the number of battery life, due to the consumption of electrolyte and battery internal chemical activity in the reduction of internal resistance of the battery will have different degrees of increase. The worse the quality of the battery up faster. Cycle life batteries that can be experienced repeated charge and discharge cycles to Dell Inspiron 510m Battery VGP-BPS9/B Sony VGP-BPS5. Battery life and capacity into the inverse relationship, the general Ni-MH battery cycle life of up to 500 times or more. High-capacity battery life is shorter, although up to 200 times or more. With the charge-discharge cycle life is also closely related to the conditions, generally the greater the charge current (faster charging), the shorter the cycle life.

Charge retention ability that is often talked about self-discharge, that means open-circuit state, the battery storage of electricity in certain environmental conditions to maintain the ability. Mainly by self-discharge battery materials, manufacturing processes, storage conditions, and many other factors with Sony VGP-BPS2  VGP-BPS9/S Dell Inspiron 1721 Battery. That the large current discharge capability. Digital cameras, power tools, electric toys, electric appliances in particular need to have excellent large current discharge performance of the battery. Large current discharge performance of primary and battery-related materials and production processes.

Usually the higher the temperature the greater the self-discharge rate. Rechargeable battery to a certain extent of self-discharge is normal to apple a1036 adapter or 45Wh Apple PowerBook G4 Adapter. With nickel-metal hydride batteries, for example, IEC standards require that the battery is fully charged after the temperature of 20 ± 5 ° C, humidity 65 ± 20% conditions, the open set aside 28 days, 0.2C discharge time of not less than 3 hours (ie, residual consumption is greater than 60%). Lithium-ion batteries and dry battery self-discharge is much smaller than Dell Latitude D620 Battery.

Activate the "aging" of the laptop battery

Activate the "aging" of the laptop battery

When the laptop screen shows the Sony VGP-BPS9 battery is damaged,what will you do? Therefore, the battery maintenance and rehabilitation needs of laptop users is the topic of concern. Maintenance process is also often referred to as "activation", "activation", a very vivid and to reflect that the battery "dead" and rebirth process.

I summed up the activation of a battery approach, its basic principle is that when the charge and discharge currents must be small (but not too small, or too long), there is to try to be filled, released completely. Cell damage because the battery in use after a period of time will "aging" of Asus A2 battery Asus A42-A2 battery Asus W5A battery. Concrete expression of the resistance is bigger, at charging time at both ends of voltage rise faster, so it will be easily found for the charge control circuit has been filled, the capacity also is naturally "down". Since relatively large battery internal resistance, discharge voltage drop by high speed, the system can easily mistaken for a voltage not enough, lack of electricity (in fact, there is no electrical discharge).

Can be seen from the above description of the battery is a vicious cycle of aging process, the discovery of lost working hours, the battery faster than when what it should be tempered, or else it will be finished sooner or later. In addition, many lithium battery failure is the battery package of a certain energy-saving result of core failure, a bad pot of soup mouse droppings. This phenomenon can not be avoided, because the battery power-saving core of each character can not be fully consistent with a long time there are some quality to Sony VGP-BPL8 Compaq Evo N600C Battery Compaq Evo N610C Battery, the aging first weakened, undermining the whole (series after) the discharge curve. It simply means that section of bad batteries before charging full discharge also finished first place, but this time the capacity of the other batteries have not been fully utilized.

The core of a power-saving overcharge / over-discharge will not cause the battery monitoring circuit that the whole is full of / discharge end of the. For example, when charging other batteries start getting close to full charge when pressed, that section of bad batteries may have reached the terminal voltage of 4.30V or higher, resulting in overcharge damage, while others are sufficient dissatisfaction. Editor's note: For internal batteries battery damage, the "Chinese computer education" 2001 No. 2 has a very good article - "notebook computer batteries DIY" worth learning from. Interest, courage and capacity of friends can try to open the battery pack, believe that the help of multimeter to Compaq EVO N400c Battery Compaq EVO N410c Battery Compaq Evo N600 Battery, you can quickly find the damaged batteries (voltage abnormality). If conditions permit, according to the corresponding parameters of the replacement batteries can be qualified product. The battery charge and discharge lithium-ion battery charging poses as a way of fast charge constant current in the voltage reaches a certain value and then to slow charging constant voltage mode. Notebook computers are often not strictly a constant-current charge of monitoring devices.

System load when a large charge current on small, whereas the large, the current from the AC power adapter power margin decision. Clearly, the system will charge the battery and other components, such as CPU, hard drive, LCD and other competing energy sources to Dell Inspiron E1505 Battery. I tried to run side Superπ, while charging the way and found that the charge current in the 0.70 ~ 1.70A between the changes, can not meet the lithium-ion battery charging requirements, so I fear that this will work, rechargeable batteries were defective to Compaq Evo N620C Battery Compaq EVO N400 Battery. IBM statement calling for notebook computers will not operate when the charge is probably the reason. Charge at boot time, if we can select the charge mode, you do not choose fast charge mode (Express charge mode), to avoid premature battery "full."

There is a time of low battery power to prohibit the use of the highest CPU performance in order to reduce the power of the competition. If the notebook computer's CPU is to support the use of SpeedStep technology, it is best to install the driver (the vendor will be responsible installed) to facilitate the adjustment performance to Compaq EVO N410 Battery Pavilion ZD8000 Battery. SpeedStep program icon is a blue flags, right-click performance tuning options it can occur to powerbook g4 adapter . Under the Windows XP system, SpeedStep program will be problems, this time to rely on or to modify the BIOS parameters of the regulation of a number of brand-specific programs, such as IBM notebook computer software is very powerful tool.

Electrical discharge of lithium, or always-on, let the natural discharge better. Is best not to use physical methods (string of resistors in the class). Not to say that that was not feasible, but relatively large risk, if the internal protection circuit was not working, then set aside the batteries as Dell Latitude D800 Battery Dell Inspiron 510m Battery VGP-BPS9/B battery VGP-BPS9A/B battery, and the worst is probably the battery explosion, of course, this unlikely. Circuit hidden dangerous is not impossible, a number of big-name manufacturers have found that the design of potential risk factors exist in a battery recall, as mobile phone battery when you do not hear the explosion.

Little knowledge:

Generally speaking, laptop battery protection circuit in the part is usually voltage block, control chip, insurance, and temperature probes by Compaq EVO N610V battery Compaq EVO N620C battery. Temperature protection device is usually a one-off, the inside has a fuse (some 130 ℃ Fuse), is used to monitor the voltage regulator block work with powerbook G4 ac adapter. If the charge-discharge process exceptions, immediately there will be a current through the temperature protection device, will fuse fuse, the battery's internal circuitry at this time for the open circuit state, and can not be restored.

If you want to repair only the replacement of temperature protection device, but such temperature protection device on the market hard to find. Discharge is the discharge current as small as possible, the operation is to slow down and let the CPU, hard disk stops turn Inspiron 1721 Battery Sony VGP-BPL8 Compaq Evo N600C Battery, transferred the darkest the screen (or close the switch off), then do not run any programs until the laptop automatically shut down. The emphasis on small-current discharge is to prevent premature detection of laptop battery shortage. I have disabled the hard disk, close the screen, cancel the power of the state police under the laptop completely discharge (put a close to 6 hours), the battery capacity from 31.72Wh restored to 33.65Wh or 65Wh Apple PowerBook G4 Adapter.

Apple new product , new environmental report

To Apple laptop battery's view, a company's degree of influence of the environment primarily from its product access and make use of the power generated by energy consumption. This is also an important factor affecting the environment you have. So, Apple is committed to designing energy-efficient products. In fact, every new Mac computers are in line with ENERGYSTAR stringent ENERGY STAR specification for low-power requirements. Lower energy consumption reduces energy Compaq EVO N400 Battery Compaq EVO N410 Battery Pavilion ZD8000 Battery costs and reduce greenhouse gas emissions from power plants impact on the environment.

• Power

Reduce the Sony VGP-BPS8 battery's energy consumption in three ways: the use of more efficient power supply, the use of low-power components, and the use of power management software. Apple-based company's products due to manufacturing of hardware and software systems, we are able to make use of all three methods.

Apple custom design a highly efficient power supply, can reduce the power from the wall to the computer generated when consumption. Mac system uses energy-saving collaboration with the operating system and smooth hardware components in order to save power. Mac OSX slow down for the hard disk in a timely manner Dell Inspiron 1721 Battery VGP-BPL8, for energy-saving features already have LED display to start sleep mode. Can also be a balance between CPU and graphics processor tasks. Mac OSX will never miss any chance to even the tiny energy-saving.

Can even among the percussion buttons adjusts the processor, enter the gap in your energy-saving. This is just the Apple start from a large number of details to achieve a substantial section of electricity, one of the many ways.Today's iMac is Apple perfect example of energy-saving design Sony VGP-BPS2� VGP-BPS9/S. iMac power consumption in idle mode than the previous generation product by 30%. This means that four years could be reduced to 18% of greenhouse gas emissions. Only Cikuan iMac, product improvement by the reduction in carbon emissions, it is almost equivalent to our institutions of all facilities that generate emissions.

• Energy Star certified

iMac meet the EPA's stringent low-power specifications, and received ENERGY STAR Energy Star certification. ENERGY STAR Energy Star 5.0 standard not only improve the efficiency of the power requirements, while the annual power consumption of the computer also made strict demands.

Apple laptop battery line in each computer are in line with ENERGY STAR Energy Star standards. Apple is the industry to make such a statement of the companies. Mac desktop and portable computers even in the ENERGY STAR 5.0 version of the specification in July 2009 before the entry into ompaq Evo N600C Battery Compaq Evo N610C Battery force of the early achievement of its latest energy efficiency requirements. ENERGY STAR5.0 significantly increased the effectiveness of restrictions on the power supply, and annual power consumption of computers standards set more stringent standards. Energy-saving design can not only save energy, but also to reduce greenhouse gas emissions, the largest single product on the environment.

• Durable products

Apple designed the product durable. Apple MacBook Pro 17-inch's built-in battery is a perfect example. Other laptop battery can only charge 200 to 300 times. MacBook Pro battery rechargeable up to 1,000 times 1.In order for you to save money, reduce waste and extend the product life MacBookPro.

A high degree of recyclable products,When the Apple MacBook Pro 13-inch finally the end of a long life, it can be reused for raw materials used in other products. Apple products use aluminum, polycarbonate, glass, high-quality material, great recycling value.Apple Recycling Program

At the same time, Apple provides free of the old Apple computers, monitors, iPod, and iPhone recovery service.

• iMac and the Environment

Apple in product design at the beginning had been taken into account environmental protection needs. That is why the iMac is more energy-efficient, does not contain many toxic substances, and highly recyclable.

• Efficient Power Supply

iMac is equipped with very efficient in power, can reduce the power from the wall to the computer generated when consumption. Reduction in power consumption, not only reduces electricity costs and reduce power plant emissions on the environment impact.

• Advanced Power Management

Unlike many Windows-based PC systems are different, iMac using energy-efficient hardware components may fight side by side with the operating system in order to consume less power. Mac OSX in a timely manner for the hard disk slow down on the already energy-efficient LED-backlit display running start sleep mode EVO N400c Battery EVO N410c Battery. Can also be a balance between CPU and graphics processor tasks. Mac OSX will never miss any chance the tiny energy-saving. Can even among the percussion buttons adjusts the processor, enter the gap in your energy-saving. This is just the Apple everywhere tightening budgets, energy savings add up one way.

• Less toxic substances

Today, we are the industry's biggest environmental challenges is the product of the existence of arsenic, brominated flame retardants (BFR), mercury, phthalates and PVC. Apple engineers to work in the iMac circuit boards, internal cables, connectors, insulators, adhesives, etc. in order to stop the use of brominated flame Evo N600 Battery Evo N620C Battery retardants and polyvinyl chloride 2. In addition, Apple has also put an end to many in the computer manufacturing process generally used in a number of toxic substances, such as, iMac display is not backlit display mercury and its arsenic-free glass.

The Llithium Batteries' work style

The Llithium Batteries' work style

In addition, in some cell phones, collecting more than a certain time if it starts not remove the charger to stop, this time only for billing system discharge - charge cycle. Perhaps it is the manufacturer of this approach, its own purposes, it is clear that the EVO N400c Battery Compaq EVO N410c Battery and cell phone charger is a disadvantage in terms of life expectancy. At the same time, long charging would take advantage of a long time, often at night, but our power grid situation, at night in many places higher than the voltage, but also volatile.

As noted above, the lithium batteries is very precious, and it is more than nickel in the electric charge and discharge aspects of fluctuations in the ability of the resistance is much less, so this brings additional risk. In addition, another aspect can not be ignored is the lithium battery is also not suitable for over-discharge IBM 92P1097 battery IBM 40Y6793 battery IBM FRU92P1121 battery, over-discharge of lithium batteries is also very unfavorable. This leads to the following questions.

Iin normal use it should start charging. Recharge in our forums, often the argument that because the number of loading and unloading is limited Asus A2 battery Asus A42-A2 battery Asus W5A battery Asus W1 battery, so that the phone battery to be used as much as possible. But I found one on the lithium-ion battery charge and discharge cycle test table, on the lifetime of data is as follows:

Life (10% DOD):> 1000 times

Life (100% DOD):> 200 times

DOD is the depth of discharge, which the English abbreviation. Can be seen from the table is the depth of the charge and discharge times, 10% DOD is lifetime than the 100% DOD for much longer. The course when they meet the actual costs relative to the total capacity: 10% * 1000 = 100,100 * 200 = 200%, the latter a full charge and discharge, or better than some, but to say to friends that some of the changes: In normal case You should have a spare battery is almost empty, in accordance with the principle of the left side carry disposal charging again, but if you can not use your Evo N600 Battery Compaq Evo N620C Battery in your first two days, expect that in the last entire day, if it was timely for free start, of course, if you are willing to return the charger to the office again a different matter.

And you need to recharge for busy with the next expected communication needs will result in a major event about VGP-BPS2 sony VGP-BPS8, although there are a lot of battery power over time must, then you just charge ahead, because you can not really be lost "a" sub-charge lifetime, ie "0.x" times only, and is often very disturbing.

Run the battery is empty and then fill the rest of the principle do not want to go to the utmost. And as long as the loading of a widespread view that "as far as possible the cell phone battery runs out, it is best to use automatic shutdown." This is really only practical on nickel batteries, is the goal, the memory effect occurs on Compaq EVO N160 battery Compaq EVO N800 battery Compaq EVO N600 battery, to avoid, but unfortunately it is also of lithium batteries for this to spread. It is too low because the cell phone battery warning appears, still does not burden continues to use the sample that was used in the automatic shutdown. The results in this case, cell phone fees from, and later in the no response, had to contact customer service to give overhaul. In fact, this is because the battery caused by excessive electrical discharges in low voltage, so that the normal cost and the boot and conditions.

for lithium batteries cell phones right track. In summary, I have used lithium batteries in cell phones charging and discharging, the most important tips:

1, are consistent with the standards and procedures to powerbook G4 ac charger, charging time, even the first three to do so;

2, when the phone asked if the current is too low, we should try to now be loaded on time;

3, do not enable lithium batteries to the particular method in a normal cell phone use lithium batteries such as PCGA-BP2NX Sony VGP-BPS2are naturally active. If you insist on promoting the use of "the three previous 12-hour long activation charge" approach, in fact, there is no effect.

Hence all the pursuit of super-long 12-hour lithium battery cell phone use and the integration of the practice of automatic shutdown APple A1021 charger, false. If you have previously done in accordance with the false argument correct, please in time, perhaps not too late.
