Newest SAMSUNG 300U1A 305U1A 305U1Z notebook battery knowledge

In my own experience with the laptop, I think the use of laptop batteries and maintenance, can not long be left unused, not suitable for long-term set in a notebook with an external power supply used, this would allow the laptop battery is repeatedly charge and discharge, but did not play the role of the battery to the limit, here I share some ways to use the battery, what is the appropriate place, also hope you master the wing.

But in general, can be so considered on the laptop battery, power outages often occur in some places, laptop or connected to the battery used in conjunction with an external power supply is better, although the battery would be more wear and tear, but it helps protect the notebook , laptop battery more expensive than the price, which must be clearly aware of; in some major cities like, the power supply more secure, we can first consider the protection of the battery, after all, the case of UPS, laptop power supply side or will not be any harm.

My laptop battery is usually not set in a notebook, and probably about the time interval of one month, I installed the battery is not connected external power supply, is it so simple to use battery time about two hours, set the battery alarm time is 5%, see the power prompted, connect the external power supply to continue to use, observe the battery charging case, at least not in a fully charged battery before pulling power, shut down the future, they disconnect the battery, use it just take the next boot external power supply so the cycle, the laptop battery that is used once a month or so, once again full of electricity, which helps protect the battery to extend battery life, after all, not how cheap laptop battery Well.

It is now very common to travel by plane, but some precautions plane, I think we do not fully understand. Generally when the plane is very boring, the way people used to pass the time nothing more than to see the book, the newspaper. Most people know when the plane can not open the phone, pagers and other communication equipment, but whether the laptop can not very clear. Most people would say, open the phone, there will be some signal interference on aircraft radar, navigation equipment, may result in the control of aircraft and personnel on the ground contact break. But the laptop does not matter, anyway, I do not go. So please, when you fly on to open the laptop and play games, watch movies to pass the time.

Battery in use for some time and then will aging. Specific performance is the internal resistance becomes large, in charge when both ends of the voltage rise faster, so it is easy to determine the charge control circuit has been filled to capacity will naturally be "down". As the battery internal resistance is relatively large, the battery in use for some time and then will aging. Specific performance is the internal resistance becomes large, in charge when both ends of the voltage rise faster, so it is easy to determine the charge control circuit has been filled to capacity will naturally be "down". Since relatively large battery internal resistance, discharge voltage drop, high speed, the system is easily mistaken for a voltage not enough power is low (in fact, there is no electrical discharge). As can be seen from the above description the battery is a vicious cycle of aging process, the discovery of battery life out of time faster than what it should be tempered, otherwise sooner or later will end.

Battery charge and discharge:
Lithium-ion battery when the first way to fast charge constant current, the voltage reaches a certain value and then to constant voltage trickle charge. Laptop computers are often not strictly a constant-current charging control device. System load when the charge current is small, whereas on the large, the current from the AC power adapter power margin decision. Clearly, the system will charge batteries and other components, such as CUP, hard drive, LCD and other competing energy sources. While I tried to run Superπ, while charging the way, found that the charge current varies between 0.70 ~ 1.70A, can not meet the requirements of lithium-ion rechargeable battery, so I fear that this work, charge the battery will be damaged. Instructions on the requirements for IBM laptop not charging operation is probably the reason.

Charge at boot time, if we can select the charge mode, do not select the fast charge mode (Express charge mode), to avoid premature battery "full." There is a time of low battery prohibit the use of CUP's highest performance, in order to reduce the power of the competition. If the laptop using the CUP is to support the SpeedStep technology, it is best to install the driver (responsible manufacturers are installed) to facilitate the adjustment performance. SpeedStep program icon is a blue flags, right-click performance tuning options it can occur. In Windows XP system, SpeedStep program will be problems, this time to modify the BIOS parameters can only rely on a number of brand-specific regulation or procedure, such as IBM laptop is very powerful tool.

Discharge of lithium or always-on, let the natural discharge better. Best not to use physical methods (string of resistors and the like). This is not to say no, but the risk is relatively large, if the internal protection circuit did not work, then set aside a whole battery, the battery is probably the worst **, of course, this is unlikely. Circuit hidden dangerous is not impossible, and some of the big manufacturers have found that the design of the potential risk factors and a battery recycling, as when the mobile phone battery ** not heard of.

Tips: In general, notebook computer battery protection circuit in the parts usually block regulator to control the chip, insurance, and temperature probes. Temperature protection device is usually a one-off, the inside has a fuse (fuse some 130 ℃), used to monitor the voltage regulator block work. If the charge-discharge process exceptions, immediately there is a current through the temperature protection, the fuse blows, the circuit inside the battery at this time for the off state, and can not be restored. If you want to repair only the replacement of temperature protection, but such a temperature protection device on the market is difficult to find.

Discharge is the discharge current as small as possible, the operation is slow down and let the CUP, hard stops, the darkest tone screen (or closed off), then do not run any programs until the laptop automatically shut down. The emphasis on small-current discharge is to prevent laptop battery voltage is detected early enough.

Whether people in the office with a laptop, or gaming entertainment, when most of them will put a drink next to the laptop, sipping of coffee, while the work is a pleasure ah. Here I must remind you, if you have been careful, you can not achieve their goals, no matter what your means, as long as the dumping of glass, liquid spilled on the keyboard, the task is completed.
   
Notebook and desktop is not the same, if the water spilled into the latter's keyboard which, at most, result in damage to the keyboard, a big deal to change an ordinary keyboard did not have much money. But if the water spilled into the notebook computer keyboard inside, then it may not be able to solve for a keyboard problem. Hidden underneath the keyboard in a notebook motherboard, hard disk, CPU and other important and fragile accessories, the slightest mistake can cause hardware damage, if any liquid gets into the laptop inside, then the consequences would be disastrous. Of course, if you are watering after the power immediately, and the water can dry as possible, it is likely not complete the task - on the notebook into the fire, except dried.

Read the "X-Men" movie friends will remember that film villain - "Magneto King", was covered can emit magnetic him, I can only use "super" to describe. Although in real life there is no such person exists, but in people or things around with a lot of magnetic force, the most common is when the number of magnets, speakers, glass and other items of the magnetization. You need to do is very simple, as long as the notebook on the long-term speaker, next to the magnet, and you're done, though not immediate, but can be called a "suicide" is dead, but also make it to a semi-disabled, what screen color cast, data loss, not to mention.

In the course of using the notebook will also emit radio waves at different frequencies and signals, which may interfere with aircraft pilots and ground command and communication links, and even aircraft autopilot would send the wrong interference to flight instruction security. According to statistics, many air crashes are caused because of these reasons, so you if you want to enjoy a few kilometers altitude free fall, then you quickly open the notebook.
