With the development if the science and technoligy,hp nc6000 battery are becoming more and more important in powering our computer and other electronic.Battery research is focusing heavily on lithium chemistries, so much so that one could presume that all portable devices will be powered with laptop batteries in the future. In many ways, laptop is superior to nickel and lead-based chemistries and the applications for laptop batteries are growing as a result.
laptop has not yet fully matured and is being improved continuously. New metal and chemical combinations are being tried every six months to increase energy density and prolong service life. The improvements in longevity after each change will not be known for a few years.
A laptop battery provides 300-500 discharge/charge cycles. The battery prefers a partial rather than a full discharge. Frequent full discharges should be avoided when possible. Instead, charge the battery more often or use a larger battery. There is no concern of memory when applying unscheduled charges.
Although laptop is memory-free in terms of performance deterioration, batteries with fuel gauges exhibit what engineers refer to as "digital memory". Here is the reason: Short discharges with subsequent recharges do not provide the periodic calibration needed to synchronize the fuel gauge with the battery's state-of-charge. A deliberate full discharge and recharge every 30 charges corrects this problem.
Letting the hp nc8000 battery run down to the cut-off point in the equipment will do this. If ignored, the fuel gauge will become increasingly less accurate. (Read more in 'Choosing the right battery for portable computing', Part Two.)
The speed by which laptop ages is governed by temperature and state-of-charge. Figure 1 illustrates the capacity loss as a function of these two parameters.
The mentioning of limited service life on laptop has caused concern in the battery industry and I will need to add some clarifications. Let me explain:
If someone asks how long we humans live, we would soon find out that the longevity varies according to life style and living conditions that exist in different countries. Similar conditions exist with the batteries, laptop in particular. Since BatteryUniversity bases its information on the feedback from users as opposed to scientific information derived from a research lab, longevity results may differ from manufacturer' specifications. Let's briefly look at the various living conditions of the laptop battery.
The worst condition is keeping a fully charged sony vgp-bps2a battery at elevated temperatures, which is the case with running laptop batteries. If used on main power, the battery inside a laptop will only last for 12-18 months. I must hasten to explain that the pack does not die suddenly but begins with reduced run-times.
The voltage level to which the cells are charged also plays an important role to longevity. For safety reasons, most laptop cannot exceed 4.20 volts per cell. While a higher voltage boosts capacity, the disadvantage is lower cycle life. Figure 2 shows the cycle life as a function of charge voltage.

A good battery is important and there are many things about the laptop battery that people seem to forget or never know in the first place that are very important to the proper care and use of your laptop and your laptop battery. The first, and probably most important, rule about laptop batteries is you should never open your laptop battery for any reason. Your laptop battery is sealed so that it works properly and there are dangerous chemicals inside a laptop battery that can cause serious damage to your skin if you come in contact with them and very serious damage if those chemicals get ingested by anyone. So never open your laptop battery for any reason. You are more than able to remove the battery from your laptop if you have the need and it is very simple to do that. Just follow the battery removal instructions in your laptop user guide and remember to take it very slowly when you are removing your laptop battery. It should be very easy to remove your laptop battery and if you experience any resistance trying to remove the battery then something in your laptop could be damaged so take it to a repair shop.
Use a full charge cycle before recharging. All laptop batteries in our site are Li-Ion batteries, so, they do not have memory which you might find in NiCad batteries. However, each chemistry has a limited number of charge cycles, so use a full charge cycle before re-charging to maximize your battery usage. When charging your Laptop notebook battery for the first time your computer may indicate that charging is complete after just 10 or 15 minutes. Don't worry, this is normal with rechargeable batteries. Just simply remove the Laptop battery from the laptop and repeat the charging procedure.
Try To avoid over-charging, especially, do not let your laptop battery over discharge. It is normal for Laptop notebook battery to become warm when charge and use you battery. The battery exhaust much faster under the high temperature, you should avoid using your toshiba pa3366u-1brs battery in shady, cool place. Hit the battery, and other acts will also accelerate depletion of battery. So, pay attention to your battery as much as possible.
If you don't use your Laptop batteries for 1 month or longer, you should remove the battery from your notebook, make sure leave your battery power about 40%, stored in a shade, cool, dry place away from heat, metal objects and direct sunlight, but not in the refrigerator. It's objected strongly store your Laptop laptop battery for over three months without any using. A charged ACER laptop battery will eventually loses its charge if unused. It may therefore be necessary to recharge the battery after a storage period.

Do-It-Yourself to improve laptop battery cooling
laptop in the use of a period of time, cooling the mouth parts of easier access to the dust and filth, with the passage of time, the dust and dirt flooded CPU fan and heat sink between the gap. When the fan spinning, when the plug because of the dust will be particularly great voice, and heat sink lead dust clearance time duct blockage, so that convection can not be normal, so do not smooth the wind noise is the biggest factor in dell inspiron 9300 battery the laptop. Removed the primary CPU fan and heat sink, the removal of different methods of different laptop.
We can see the product manual attached, fans and heat sinks get down at this time fans will find a lot of dust between the fan, use hair dryer (with wind) surface dust, then use alcohol to clean the cotton pads carefully cleaning up each rotor blades and the center of the dirt. Similarly, the other end of hp dv9700 heat sink as a result of very fine pore, and can only use hair dryer blowing. All work is completed, by the same method installed fans and heat sinks, the boot, you will find that the noise has decreased laptop.
CPU fan clean up the dust, if the heat is still not ideal for a laptop with dell inspiron 9400 battery an external heat sink, for example, prices of about 50 cards laptop cooling, laptop cooling use PCMCIA card inserted into slot, and then USB Line access USB interface, when the cooling fan on the card can be rotating hair style in order to enhance air flow inside the laptop and laptops to solve the problem of fever.
Can also add a heat to the laptop chassis, the principle is set up in the laptop at the bottom of the high-speed fans, and heat the base material is usually a good thermal conductivity of the metal, and great air circulation through the metal heat sink for heat dissipation for the laptop cooling, the products in the accessories market is readily available, the price of 100 yuan, will use the laptop on a fixed base in the heat, heat the base will be able to access USB interface to the heat.

laptop keyboard maintaince
Since the keyboard is the most frequently used one of the components, although many manufacturers have to take into account its durability, especially in the structure was fully optimized, but the water droplets to wear stone, the problem a long time coming. Either not used a key or letter is not a grind. When users should pay attention to the following major points: the first is not to temper the keyboard. It seems to hp dv2200 us that the keyboard is the biggest killer of your own, many laptop users in the crash after the results of the work as a result of the loss of their own, are smashing the keyboard will not help a few gas exports. We remind you that the keyboard keys to do so will play a supportive role in the damage to the soft, there will be a long time the button press does not go up the issue of shells. The second point is that as far as possible not to eat the top of laptops, smoking or drinking, keep the keyboard clean.
In particular, too much liquid into the keyboard, is likely to make short-circuit, resulting in the loss of hardware. We hope that users can develop a good habit to eat or drink when away from the laptop, which will minimize the chance of problems, to achieve the purpose of protection of v3000 laptops. Secondly, we suggest that you can buy a laptop-specific soft keyboard, which a lot of soft surfaces above the key-bit, just to cover the keyboard on the laptop, can waterproof, dust-proof, but also anti - grinding, and the price is not expensive, generally able to buy the PC market. In addition, regular use of clean cloth to remove inter-key gap in the dust is also very necessary.
For those who have flooded the keyboard is not flexible or user, we'll teach you. First of all, the laptop to pull each key can be opened. For standard-sized keys, you use a fingernail to hp v6000 pull from top to bottom can be hard to pull the open, to be followed by a rubber pad, button shells do not like it up well. Shells for the button press is not up users, you can click this rubber hand pad, If you can not then you can use other keys used with the rubber pad in lieu of, or laptop to buy a second-hand market , the price is very cheap, at least you stand to get much cheaper maintenance.
Water users for the keyboard, you need to water it all to pull one of the keys to open, after careful examination, if it is determined that there is no leakage of liquid into the internal laptop, then the distilled water or tap water and so on, can be dry For drinks, such as Coca-Cola, which drinks water evaporation will leave a sticky stem of the sugar, then you will need to use low concentrations of alcohol for cleaning. It should be noted that, when rubbed in every corner, especially the parts of rubber. Well, that simple, how? You have begun to do it?
