Three points of disagreement about how to use laptop battery





Disconnect the battery when using external power . Views 1: Remove the HP KS524AA battery when using external power. View 2: don t need to remove the battery when using external power.
Poll: Most students take out the battery in the use of an external power supply, only a few students stay connected on the laptop battery when using external power, which a small number of students are used in many international brand-name brands.


HP PB992A battery proposed method: in fact, the battery must be removed or not, depending on whether the battery is recharged while in the use of external power. Should know that the life of lithium batteries is directly related to charging and discharging times, even set the number of charging and discharging times is constant, the number of charge cycles only 400-800 times. The first point of view is nothing more than fear of energy use, the battery is charged, not only increases the number of charge cycles and will cause excessive loading. The second view that the battery is full power on the computer, the use of external energy sources will not be charged.


In fact, both views of their right hand, but also a bad side. Because it is only the views expressed by individual people, not very extensive, after my research, many notebook manufacturers take into account the sensitivity of the battery and the product will be added to protect the battery technology, and therefore suitable for notebook batteries of different brands for different protection technologies, such as some big companies in this area is very good, such as IBM, HP, Toshiba, Compaq, etc. Which is considered the most thoughtful of ibm, HP KS526AA battery power to detect a situation, the ThinkPad notebook battery is automatically recharged only when less than 95%.


This can play a very good protective effect of the battery, and now there are so many other manufacturers to follow. In this connection, that the battery in this way, you do not need to use when drawing down because only when the voltage is lower than the 95% of the time will be charged. However, the HP KS525AA battery is recommended to be removed if the computer is in use for a long time, because the heat generated will cause damage to the battery. Each access to the external power supply to charge the battery is considered one, but only a small fee will be a period of time. It is proposed that all the time in the use of the machinery in accordance with their situation, manual notebook check to determine whether the battery should be removed when the use of an external power supply.

Notebook battery last longer






batteries are there to deflate. the only question is how long it will take for you without that energy is noodzakerlijke your laptop alive. luckily computer language some traveling die-hards among his editors who give you their best tips aanbieden longer so that you can work with your computer without taking a lot to lose.
1. Never open more applications than you really need. I know it on my computer often several applications open. it is convenient, but it consumes quite a bit of your HP HSTNN-DB72 battery time. open, so only those programs that you really need and limit the use of software that the limit of your computer questions.


it is often useful to those little icons in your taskbar hbeben. so you know immediately what is available, and what not. beginning but by disabling your firewall and antivirus application when you are not using the Internet. also get all the services road you do not really need. the settings of your graphics card, skype or any other application you may feel off while traveling, provided of course you do not do anything with those files and you just need some programs. once you're somewhere where you do need that, you can just restart the computer immediately and puff ... everything is as you like it.



You have the computer needed for Office, start you travel with, for example, not to watch a dvd or a game to play. Which applications require quite a lot of energy.Adjust the brightness of your screen. Minimize this to the level at which you still can see everything well enough. The less light you screen displays, the less energy you will consume. How you do this varies from computer to computer.switching off unnecessary hardware components. we are thinking of your wireless network (wi-fi) or your bluetooth. Some laptops allow you to switch directly from a button, but usually you will still have to do it in windows.Click on Start. Right click on my Computer and choose Properties.The System window opens.
Now Open the Hardware tab. Click Device Manager. Go to the hardware component that you want to disable.Right click and select Disable the option in the shortcut menu that appears. Keep in mind that the device no more hereafter will work!You can now simply close all the Windows.Do you want to re-enable the hardware, you need to repeat the same procedure, but then click Enable



gives as much as possible external hardware path. a USB stick that you can not geruikt, live or from your HP HSTNN-DB42 battery . also pcmcia network cards and other connections can you best connect only when you actually need it. Connect an iPod or anything else, you can also best to postpone or already on hand for finishing.Keeps the temperature in the eye. A battery is functioning less optimal when the temperature is too high. Court of Auditors with normal room temperatures between 18 and 22 degrees. It Is warmer than say 25 degrees, we recommend you to turn off your computer and wait until the temperature drops.besparede energy features of your computer are useful, but it's not because your computer to sleep is that he no energy. opteis then use this responsibly.


Maintains the HP HSTNN-DB28 battery . Make sure you get the notebook used frequently without feeding. When you don't have a Li-ion battery not completely flat to use. Who has an older nickel, does that better gebazeerde version though. So do you make sure your battery lasts longer.Li-ion batteries are perishable in time but. Once they come, they go quietly from the factory band death. Just use these batteries on the duration without prevents you get stuck.Regularly defragment your hard disk.You do that by opening My Computer. This time then you right-click the hard disk that you want to defragementeren. On the shortcut menu, click Properties.Open the Tools tab and click on defragment now. Click here click Analyze to let verify that defragmentation is needed. Possibly you can still view the report.


A tip that always works: mount your computer once in a while to your nutrition. You will be surprised about the time that now you suddenly can work.They are small tips, but tips that you can make it work while all other users quietely long to a death stare screen. When your HP EV088AA battery is almost without life in you, do you also good on the tasks that you should perform according to priority. United eventually your battery out then you can clap with clear conscience you portable computer, knowing that you've taken out the maximum.

How to care for hp laptop batteries





Integral part of your laptop battery is a battery, which gives the possibility to use it anywhere without connecting to the mains. Hand in hand with wireless network interfaces gives the previously unimaginable freedom to choose their place of work - from the living room, the backyard to the cafe in the city center and the airport on its outskirts.
But many people do not feel the need to move your computer out of range of outlets, the power grid. Then HP 500 battery becomes unnecessary ballast, and when the moment comes when a moment is needed, it appears that long ago "gave up the ghost" and the computer does not support even for a few seconds.


This text is to acquaint you with the use of lithium-ion (Li-Ion) to ensure their efficiency throughout their operations, regardless of whether you spend most of their time on the road, or using a laptop as a deputy of classical , dealing with cumbersome and plenty of space on your desk PC. Device whose operation is based on chemical reactions must have its durability. In the case of lithium-ion HP PF723A battery for proper operation is usually about 2-3 years and is calculated from the date of manufacture. After that time will clearly lose battery capacity, and in extreme cases when it comes to internal short circuit of one of the cells in general no longer function.


Therefore count the fact that you're not blowing and blew the battery for a few years you will probably still buy new , even if you have used the current very rarely and carefully. Although it is worth to take care of the correct use of the HP WD549AA battery : wrong use can refuse to act even before the expiry of two years, a properly maintained can survive fourth birthday with a little only a limited capacity. The cost of buying a new lithium battery depends on the manufacturer's pricing and capacity and construction of the battery. Count of the amount of 300 ZL in the case of simpler constructions for 700 ZL, for those more advanced.


One of the things that hurt particularly rechargeable batteries are deep discharged. A term used to discharge to the limits of capacity. After long-term recharge deeply discharged cell is usually impossible.Modern electronics protects the batteries from deep discharge, except in early enough to load in the cells remained large enough to even charge a few days gave the expected result. However, you should support this mechanism and when the Acer Aspire 5315 battery level approaches the level of warning (usually about 5% of battery capacity) to connect the AC power and recharge the battery fully.


Fully discharge but can also be "health", preventing memory effect which consists in "getting used" links to the specified level of discharge and treat it as a minimum (thus reducing its usable capacity). Cycle "discharge-charge" also helps to calibrate the sensor electronics measure the level of charge - this mainly because manufacturers recommend charge and discharge several times (formation) of each new HP WD548AA battery . Every few or several weeks, you should discharge the battery until you turn off the computer and immediately upload it back to the full. Do not be afraid of such a procedure - the computer is off before the battery is deeply discharged.


The occasion is worth mentioning about the number of limit cycles of complete charging. Will exercise greater care manufacturers define it at 300 . Even if we assume the lower values is very frequent, as for most users is the loading of every three days gives you three years work. If you loading the HP PB994A battery a long time before its full discharge and full charge carries out only occasionally, functioning cells significantly increasing and if battery refuses to act, rather "from old age", than because of excessive consumption.

Calibration the battery of laptop







Recently I wrote about extending the HP EV088AA battery by updating the firmware. Today I'm going to outline how to extend the battery life by the calibration so that it has your load correctly. After all, the ends of juice when you're on the go is the worst possible scenarios in the electronic world! As a general rule, you should calibrate the battery every month or two that could have operate in peak form.


To calibrate HP 485041-001 battery : Connect your laptop and let it completely charge (the battery icon in the menu will be completely full and the charger's connector light turns green). Keep your laptop plugged in for the next two hours (when fully charged).Unplug your laptop from power. Use it until it falls asleep from exhaustion of the battery.
Turn off the laptop and let it rest? For about five hours. Plug the laptop back and let the full charge.This is very good to use your laptop during all these operations (except, of course, when the computer is in sleep mode).


HP 484171-001 battery calibration every few months is a great way to get the longest life out of it. If I had the laptop for a while and want to know the current capacity of the battery up, you can use the free utility coconutbattery.Coconutbattery isn 't just a tool that only shows the battery charging current also shows the current efficiency than that of the original battery capacity is not as left the factory. You can also get information about the battery loadcycles (how often the full load on the battery), charger current (coconutbattery even warns you if the wrong charger connected to the notebook) and information last but not least the age of the mac.


It is easier to calibrate HP 484170-001 battery or notebook computer battery than you might think - and very useful to extend laptop battery life! The first step is to run the computer while it is unplugged until the battery is down to less than 4% charge. The computer will usually shut itself down when it gets critically low. There will be enough juice to wake it up and shut everything down properly. Then you plug in the computer and leave it to charge without turning it on for at least four hours. It can be hard to resist turning on your computer, but it is essential the computer remain off and not draw anything from the laptop battery while it is recharging.


You'll see some who will argue this advice by confiding it with the standard advice that says to avoid running your Acer Aspire 5315 battery down all the way because this "wears it out". This is true. However it's also true that the charging circuit controls charging rate based upon where it "thinks" the fully discharged level is. This is a moving target as the battery ages it's capacity lessens. The charging scheme applies a higher voltage in the initial staged and then ramps it down as it n ears a full charge. When uncalibrated, this is "off the mark" and also affects battery life.

More efficient Li-ion rechargeable batteries within 5 years






Imagine a laptop battery that stores energy for 4 hours and recharges in just 30 minutes? this dream could be closer to reality thanks to research by the University of the northwestern (Chicago - USA).A team of engineers has created a destination electrode of lithium-ion HP 337606-001 battery that allows them to retain an electrical charge up to 10 times greater than current technology. Batteries equipped with this new electrode could also be charged 10 times faster. The researchers combined two approaches in a single chemical, in the aspect of the limitation of the battery, namely: the ability and energy charge rate. Moreover, this technology could also fit into the way of electric transport with batteries are more compact. According to the researchers, it could even be on the market in the next 3 to 5 years.


"We found a way to extend the new lithium-ion battery life 10 times," said Harold h. Kung, principal author of the article published in the journal Advanced Energy Materials. "Even after 150 cycles, equivalent to operations carried out during a year, the battery still 5 times more effective than the lithium-ion HP 417066-001 battery placed on the market today."
The lithium-ion batteries are charged by a chemical reaction in which lithium ions are sent between the two ends of the stack, the anode and the cathode. When the energy stored in the battery is requested, the lithium ions travel towards the anode through the electrolyte to the cathode; was Conversely, when the battery is charged, the ions travel in the opposite direction.


With current technology, the performance of a lithium-ion batteries are limited. How long a HP 372772-001 battery can remain in office , is limited by the charge density, or how many lithium ions can be encapsulated in the anode or cathode. Meanwhile, the speed at which it is charged is limited by another factor: the rate at which lithium ions can make their way to the electrolyte in the anode.In current rechargeable batteries, anode - made of layers superimposed sheets of Graphene carbon based , can accommodate only one atom of lithium for 6 carbon atoms. To increase energy capacity, scientists have experimented with the replacement of carbon with silicon, this component may be much more lithium: 4 atoms of lithium for each silicon atom. However, in the process of loading, Silicon has adverse tendency to expand and contract dramatically, causing fragmentation and loss of fast charging capacity.


Currently, the speed rate of HP 446506-001 battery charge is constrained by the shape of the graphene sheets: they are extremely thin - only one carbon atom thick. During the loading process, the lithium-ion must travel to the outer edges of the graphene sheet before entering and coming to rest between the sheets. And as it takes time for lithium to go in the middle of the graphene sheet, a kind of "traffic jam ionic" occurs on the edges of the material.
The research of h. Kung team combined 2 techniques for combating these 2 problems. First of all, to stabilize the Silicon, to maintain the maximum load capacity, they took sandwich clusters of Silicon between sheets of Graphene. This allowed to accumulate a greater number of lithium atoms in the electrode while using Graphene leaves flexibility to adapt to the changes in volume of Silicon using.


"Now we have almost the best of two worlds," said h. kung "we have an energy density much higher due to silicon, and sandwiched reduces the capacity loss caused by the expansion and contraction of the silicon. Even if the clusters are broken silicon, silicon will be not lost. " Finally, the team of h. Kung used a chemical oxidation process to create of tiny holes (10-20 nanometers) in Graphene sheets ("in-plane defects"). Lithium-ion be thus a "shortcut" to the anode before there be stored in reaction with silicon. This has reduced by 10 in the recharge time.
