The Dell inspiron 9400 battery in use will become "aging" after a period of time, 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 is also 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). As 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 result of core failures from Dell inspiron e1705 batterypackage of a certain energy-saving . 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, 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 over charge / 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 ,such as inspiron mini9 battery 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.
The first way of Rechargeable lithium-ion battery fast charge as constant current ,when the voltage reaches a certain value ,and then slowly charge as constant voltage mode. Notebook computers are often not strictly a constant-current charge of monitoring devices. The 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. 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 KD476 charging requirements, so I fear that this will work, rechargeable batteries were defective. 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 (Expresschargemode), to avoid premature battery "full." There is a time of low pa3399u 1bas battery power to prohibit the use of the highest CPU performance in order to reduce the power of the competition.
You had better keep the computer always running for electric-discharging lithium pa3480u-1bas battery, let it naturally discharging. 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, 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.
Tip: In general, notebook computer battery protection circuit in the part is usually voltage block, control chip, insurance, and temperature probes. 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. If the charge-discharge process exceptions, immediately there will be a current through the temperature protection device, will fuse fuse, the pavilion dv6000 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.
Discharging is the discharging current as small as possible, the operation is to slow down and let the CPU, hard disk stops turn, 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 pcga-BP51a shortage.
