Notebook computers are very convenient, but often is not enough to charge the battery a little trouble there, how to deal with it
If the line is normal, or do not go red, you can see whether the battery charger circuit board bad, for a try.
Battery has been aging is also possible. General battery for about three years, basically aging, even lithium batteries. To a repair shop to check the next.
Generally need to wait for the battery to use about 20%, it needs to be recharged, and when not to wait until zero, too hurt the battery.
The battery pack with a napkin up, pay attention to pack layers, and then again with a transparent cloth twisted stick out good, pay attention to use twisted cloth glued tight, do not let the inside permeable, and then into the refrigerator (2 ---- minus 2 after Celsius in) saved 72 hours out, the battery may recover part of the storage function
On the market there are two main rechargeable batteries are nickel metal hydride batteries and lithium ion batteries, battery charge does not concern the issue into electricity for most of the two types of. The same type and size of the battery and can be connected in parallel, series and hybrid batteries composed of different combinations of cell number as a universal phenomenon, people want to know the battery and battery charging and not into the reasons behind the power and then seek solutions.
Battery charge is not into power from the big reasons is concerned, can be divided into external causes battery inherent internal reasons and battery charging implementation. Lithium-ion batteries for its superior performance is gradually occupying the original NiMH battery market, so here is mainly explained by a lithium battery charging, differentiated place mentioned NiMH batteries.
1, the battery voltage or a combination of zero zero voltage battery in the battery. Either zero voltage battery itself is nonconforming, it did not reach the factory corresponding nominal capacity and voltage values​​, either belong demise, because long-term use, the capacity is exhausted, the voltage drop to zero.
Taking into account the lithium batteries after a long hold, such as more than one year, it is possible to form the self-discharge battery exhausted so that the voltage is zero, the current lithium battery protection scheme designed to require zero-voltage battery can be charged into electricity. Thus, for a zero voltage difference between the two cells: one is to continue to use that can be charged, and the other one is no use value; in other words, the former is a reversible capacity loss, the latter being irreversible. Recharged into the electric zero-voltage lithium battery if unfortunate design to the group, it is possible to protect the chip by signaling to the zero-voltage battery pack, thereby turning off the MOSFET, the battery pack can not be charged.
2, the battery pack connection errors. The likelihood of this happening is small because the rechargeable battery or battery factory generally require full inspection, regular battery manufacturers happen unless there is no full inspection when a batch battery factory, but rather the wrong battery connection not detected in the column. Of course, for non-regular factory produced or individual assembly is another matter, a connection error and can not be completely eliminated. Relatively speaking, the nickel-metal hydride battery pack all seized some low, the probability of error may be a little larger.
3, the internal electronic components, the protection circuit is abnormal. This situation is probably occur after the battery with a long aging of electronic components, shedding will cause the battery charge is abnormal, especially integrated into the protection circuit electronic components appear to play after the above situation will directly affect the circuit protection function, and thus can not properly guide the charging process.
