Battery Wiki- Laptop battery manifestations and precautions
Battery will be used after a period of time "aging" of the. Specific manifestations of resistance become larger when the voltage across the charging up too fast, so easy to charge control circuit judge to have full capacity will naturally be "down". As the larger battery internal resistance, Bell squ-712 Battery discharge voltage drop, high speed, the system can easily mistaken for a voltage not enough, power is low (in fact there is not power up). As can be seen from the above description of the battery is a vicious cycle of aging process, the discovery of battery time out faster than what it should be tempered, or else will be finished sooner or later.
In addition, many lithium battery failure is the failure of the bag resulting in a saving core, an assumed name or bad a pot of soup. This phenomenon is inevitable, because every energy-saving battery can not be completely consistent with the nature of the core, there are some quality with long aging first weakened, undermining the whole (series) if the discharge curve. It simply means that section of bad batteries before charging full, discharge it first had finished, but this time the capacity of other batteries are not being fully utilized. Core of a saving over charge / over discharge will not cause the battery monitoring circuit that is full / End of release. For example, when charging other batteries began charging close to full pressure of time, that section of bad batteries may have to 4.30V or even higher voltage, resulting in overcharge damage, while others are fully satisfied. Editor's Note: The internal batteries for battery damage, the "China Computer Education," 2001 No. 2 has a great article - "laptop battery DIY" worth learning. Interest, courage and ability friends can try to open the battery pack, believe in the multimeter's help, Hp presario cq32 Battery you can quickly find the damaged batteries (abnormal voltage). If conditions permit, according to the corresponding parameters of batteries can replace the qualified product.
Battery charge and discharge
Lithium-ion battery charging, first by way of constant current fast charging, the voltage reaches a certain value and then to constant slow charge mode. Usually laptops are not strictly constant current charging control device. When the system load large charge current to a small, contrary to 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. I tried to run side Superπ, while charging the way, found that the charge current between the change in the 0.70 ~ 1.70A, can not meet the requirements of lithium-ion rechargeable battery, so I worry that this work will charge the battery has been damaged. IBM statement on the requirements of the notebook computer will not operate when charging 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 the highest performance CPU to reduce power struggle. If the notebook uses the CPU to support 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 systems, SpeedStep program will be problems, this time modify the BIOS parameters, or to rely on a number of brand-specific regulatory procedures, such as the IBM notebook computer is very powerful tool.
Lithium has been switched on or discharge, let it discharge better. Best not to use physical methods (like the string of resistors). This is not to say no, only relatively large risk, if the internal protection circuit not working, then the battery on the void, and the worst is probably the battery explosion, of course, this is unlikely. Circuit hidden danger is not impossible, some big companies have found that the design of the potential risk factors than the battery recall, as when cell phone battery explosions do not hear about the.
Tips: In general, the protection of laptop battery is a voltage regulator circuit components are usually block, control chips, insurance, and temperature probes. Temperature protection device is usually one-off, the inside has a fuse (fuse some 130 ℃), used to monitor the voltage regulator block work. If the process of abnormal discharge, immediately there is a current through the temperature protection device, the fuse blows, the circuit inside the battery at this time for the off state, Hp pavilion dv6 battery and unrecoverable. If you want to repair only the replacement of the temperature protection, but such temperature protector is hard to find in the market.

AT&T has begun to communicate iPhone 5 release date on September
A bevy of new information points to early September as the release date for Apple's next generation iPhone. AT&T stores are telling managers to wrap up employee training in anticipation of an increase in customers this September. The report, filed by BGR claims AT&T has begun to communicate "launch plans" to its stores regarding the iPhone 5.
Similarly, Apple stores in the UK and US have been beefing up staff and asking former employees to return. The program is typically invoked for holidays, back-to-school sales and new product launches, according to MacRumors.
The early September time frame does correspond to school starting up for students, however Apple offers discounts to college students and qualified educators year-round. Evidence of the impending iPhone 5 launch was cited by ZDNet, including earnings call sound bites from Apple CFO Peter Oppenheimer. He stated, "We also have a future product transition that we are not good to talk about today, and these things will impact our September quarter."
In any case, this is not the first time we've heard that Apple is planning a September iPhone 5 launch. Design changes, competition for component parts from suppliers, and struggling to keep up with iPad 2 demand have moved Apple off of the annual iPhone launch cycle that industry watchers have become accustomed to seeing each summer. If case design leaks can be confirmed, it seems Apple will deliver a few surprises with the next generation iPhone when it finally hits this fall.

According to Mac Rumors , the September launch sits well within the current scheme of things - "with no iPhone release during this year's WWDC, Apple is expected to include the iPhone launch at this September event alongside the public release of iOS 5.
Even though we have been constantly bombarded with iPhone 5news stories in the past months, no one still knows what to expect from Apple's next offering. While some claim to see a significant overhaul, others are pointing towards a more "bumped up specs sheet".
Earlier yesterday we reported on the iPhone 5 leaked cases . While there is uncertainty over the legitimacy of the images, the cases offer some design clues. The case revealed the smartphone to be a thinner version of the iPhone 4 and feature rounded 3GS-like back panel. There is also a indication of a 3.7-inch edge-to-edge screen, support for gesture-based controls and a larger home button.
We had also heard via a Chinese publication earlier that iPhone 5 will be NFC enabled and sport a 8 mega-pixel camera.

Share Tips to upgrades Vista laptops to lower battery life by battery wiki
Laptop owners upgrading their Windows XP and Windows Vista machines to Windows 7 are complaining that Microsoft's new OS has severely reduced their available battery life.
Microsoft claimed that the problem was in the Windows 7 tool that decided when the battery had been drained, or was unable to hold a charge. "We are investigating this issue in conjunction with our hardware partners, which appears to be related to system firmware (BIOS)," a Microsoft spokeswoman said today, referring to the firmware that boots the PC and initializes the hardware components. "The warning received in Windows 7 uses firmware information to determine if battery replacement is needed."One user tells The Reg that after upgrading his circa 2007 HP notebook from Vista to Windows 7, the machine's battery life dropped from two hours to a half hour, and countless others are voicing similar complaints on Microsoft's TechNet forums.
The problem is caused by a new tool designed to alert users when their battery needs replacing. In some cases, according to TechNet posts, this alert appears time and again - even as a battery continues to run as it always did - falsely warning that the machine may suddenly shutdown. But in other cases, the machine does shutdown prematurely. It would seem this occurs well before the battery has run out of juice.

In a statement sent to The Reg, Microsoft has acknowledged the issue, saying it's related to the way Windows 7 reads system firmware. "We are investigating this issue in conjunction with our hardware partners," the statement reads. "The warning received in Windows 7 uses firmware information to determine if battery replacement is needed. We are working with our partners to determine the root cause and will update the [Technet] forum with information and guidance as it becomes available."
According to some users posting to Technet, the issue dates back several months, to the Windows 7 beta. But others say they didn't see a problem until the final "release to manufacturing" (RTM) build. "I was having excellent battery life until I installed the RTM of Windows 7 - all RC and beta builds that I installed I had nearly three hours of battery. Now, I have about 20 minutes and Win7 shuts down my laptop," writes one user.
"This change in behavior happened when I went from an RC to RTM. Instant behavior change. Needless to say, I - like you that have posted here - [am] not happy."
Microsoft confirms that its "consider replacing your battery" warning is new to Windows 7. But the company also says that in some cases, the new tool may be working properly. In other words, if it says your battery needs replacing, it may need replacing. But for so many laptops owners posting to TechNet, this is clearly not the case.
One poster says the problem has occurred on the same machine with two different sets of batteries. "At first, I was thinking the laptop is a couple years old, and sat on a shelf gathering dust, not being stored properly," he writes. "I went to replace the batteries, and realized that HP had recalled them. So i replaced them with brand new batts from the factory. And wala! same issue."
