Should pay attention to the use of questions:
Laptop battery is a kind of "consumables," the degree of damage depends on the battery Laptop Battery when you use the battery for the correctness of the operation, the operation mode, operating frequency, the working environment temperature, storage time (for unused batteries), etc. factor.
1. Laptop battery charge and discharge frequency is directly related to battery life, in general the number of lithium battery charge and discharge of about only 400 ~ 600 times, improved product nothing but 800 times, each time the battery charge on the end to the use of a step forward . (When the power of 85% or less of the battery charge, will be recorded and to increase the number of times on a single charge.)
To this end, when the battery Compaq EVO N410c Battery voltage is greater than the battery-management process set starting value 96% charge, and your current place in which there is 220V AC power, they should make full use of AC power and minimize the number of notebook computer battery charging, to prolong battery life.
At this point the battery do not have to remove from the machine because it will not start more than 96% of the electricity to recharge the battery. But even so, if you are a long-term use AC power and rarely used the battery, it is recommended, or remove the battery from the machine to compare the good, because the long-running laptop heat generated when the battery will cause some damage. It should be noted that in such a case, once the AC-powered power outages, you have not saved data will support the absence of cell loss, this was a failure, the user must carefully Compaq EVO N400c Battery weigh.
2. When the power is 3 ~ 5%, it should be timely to charge the battery, or battery self-discharge phenomenon will cause over-discharge and damage to the battery, charging the machine and may be shut down, suspend any other state, you can also charge while edge use.
Laptop charging must be a full, otherwise it will damage the battery. This is based on reduced sufficient to avoid an increase with cycle number of charge cycles and shorten battery life; rather than due to "memory feature" issue, lithium batteries, unlike nickel-cadmium Compaq Armada M700 Battery batteries and nickel-metal hydride batteries have "memory characteristics", lithium batteries do not have the "Memory characteristics. "
If charging machine at shutdown or hibernation, when the charge to 3 ~ 4 hours after the green power status indicators are no longer beating, the time has reached 100 percent capacity, it is timely removal of the AC power plug to prevent excess charge on the battery The damage the battery.
If charging machine was waiting, hang, or side with the state of charge while, then when the charge to 3 ~ 4 hours after the green power status indicators are no longer beating, the battery will automatically exit charge state.
Charging process will carry out a fast-charging, when the power status indicator light yellow (Chang-liang), filled to a certain a certain value into the thin trickle charge current is slow, when the power status indicator light flashes green the color becomes ; has been filled with 100%, after, it becomes green (Chang-liang) of the. Lithium battery charging process is the constant pressure approach, and began charging voltage that will soon stabilize, while the current is getting IBM FRU 92P1121 Battery smaller and smaller.
3. Power is not fully depleted before (ie electricity at 5 ~ 100%), not to recharge laptop batteries, otherwise they will reduce the charge to increase with the cycle number of charge cycles and shorten battery life.
When the power is 5 ~ 95% battery should be used, so the use of AC power adapter will charge the battery (charging side by side state).
4. When the power is 96 ~ 100% or the battery removed from the machine can use the AC power adapter switched on, use the AC power adapter AC power adapter when you please put the DC output plug on the plug into the machine, and then AC power plug to plug it into 220V ~ socket; removed when the AC power adapter should be first, and then unplug the AC power plug from the machine, unplug the AC power adapter DC output plug. Otherwise, they might damage your equipment.
Using the AC power adapter, when the AC power plug to plug it into 220V ~ socket, while the power status indicator on the machine yet, gave the former IBM FRU 92P1125 Battery (Note: During this period of about 5 seconds time), please press the power button to turn; shutdown or go to sleep, in addition to green power status indicator lights have been extinguished all the other things, make a timely manner from 220V ~ unplug the AC power outlet plug (not later than 5 seconds), AC power plug pulled out in about 5 seconds , the green power status indicator light turns off; otherwise the battery will overcharge and damage caused by the battery. Off state due to AC power adapter is still non-discharge state, the system's power management procedures and battery power management chips from inside the interface circuit composed of about 5 seconds will be automatically transferred to the "off state of charge", recharge the battery IBM 40Y6793 Battery. (If necessary, may from time to unplug from the machine on AC power adapter's DC output plug, this time the battery will discharge through the AC power adapter reverse.)
If the suspension of work in order to wait for the machine to enter, or suspend state, not from 220V ~ socket unplug the AC power plug; so when the machines still have the power to maintain. (Not recommended for a long time to make the machine enters a wait or suspend state, in order to care for your machine.)
5. IBM in ThinkPad notebook computers information technology indicators have highlighted the "laptop battery" is the manufacturers are measured under the conditions specific to the indicator used in our normal notebook can not be achieved under the conditions of , such as: information technology-related indicators have highlighted the "battery" for 4 hours, we can only get the normal use of about 3.5 hours of battery power supply. If the difference is very far, and is still under IBM ThinkPad Z61t Battery warranty, dashing contact IBM.
