How do you fix your laptop battery 2011-04-1109:24
Our unit is already a notebook with a total of several hundred. People often reflect that the notebook battery is not charged, the charging time is not long enough to fill up, but it can be used quickly (only a few minutes) to prompt the battery to be low. In response to this question, I have searched the Internet, and combined with my experience, I hope to help you.
Low power slow discharge method:
1. Open the power options of the control panel and select the maximum battery mode.
2. Set in battery mode to never standby and never to sleep!
3. After the setup, the computer is put there until the power is off.
The following text is reproduced:
Today, a colleague's SONY laptop battery is broken. Let me check it. Take home inspection, the discov
ery is because the lithium battery is in low power long-term place, cause the electric core excessive discharge, protective circuit lock dead.
In this case, if you don't want to change new battery, can only open the battery disconnect protection circuit, direct extensions for the batteries voltage make them return to normal discharge above the threshold, then start charging circuit are
connected.
This practice requires a violent breakdown of the battery's shell, affecting aesthetics, and disconnecting and reconnecting circuits requires special spot welding equipment, which can be time-consuming and laborious. Directly for lithium ion batteries is very unsafe, this article comes from: XXXXHTTP: / / www.itsky.it/thread-229-1-1.html did not open the battery can restore the batteries to charge above the threshold, the method of charging circuit to unlock?
As we know, over discharge does not necessarily cause the damage of the lithium ion battery, in most cases is caused by locked circuit battery scrap, then, can in some way to bypass circuit directly recharge batteries? After research, I found every time put the battery on the system, in the first few seconds protection circuit does not begin to work, this a few seconds, the laptop charging voltage ca
十大珠宝品牌n be loaded directly on batteries, the batteries voltage rise of 0.01-0.02 V, after a few seconds, batteries began to issue instructions to laptop charging circuit, stop charging, or lock the battery. So, repeating that the battery has just inserted into the system for a few seconds, will it be able to slowly restore the battery voltage to normal?
I started experimenting. For the SONY VAIO T17C notebook, the system battery is 7.2 V / 7200 ma, inserted into the system to protect the battery, road start working time interval is about 6 seconds, so I for 6 seconds interval, plug in the battery for 6 seconds, remove the battery, and plug in 6 seconds, and repeat. Meanwhile, battery mon monitor the battery voltage status in real time. After unremitting efforts, the voltage gradually increased from 5.32 V to 5.93 V. When the voltage reached 5.93
V, the charging circuit was automatically unlocked, and the system battery began to charge the battery effectively. The battery saved the day!
After the test, the battery has reached the capacity level before discharge, and the heating is stable and the charging is the same. The experiment succeeded.
Conclusion:
1. This method can be applied to lithium ion batteries that have failed due to overloading
2, use this method to save battery is a prerequisite for batterymonitor still can see the basic information of the battery (e.g., manufacturer, serial number, etc.), chemical media, if the battery information loss caused by long-term over discharge, restores the odds.
3. Before saving, insert the battery into the system, and the system can enter the charging state of the battery.
4. The battery saved in this method is not suitable for deep discharge in the future. X健康产业

Laptop battery repair
Method one:
Laptop batteries, especially lithium battery unused for a long time or just maintenance, its charge curve and discharge curve have certain deviation, need to use real full of after a few steps to correct repair their charge and discharge curve, we also call electricity pool since the learning process.
Set 1. (this is the relationship to can repair the battery to the best of the most important step. Please
do not need to pay attention to) a open my computer e e control panel power supply option e power use solution as shown in figure 1 to use the battery of this item never alarm item b the parameters selection for the two options box, purpose is when the battery down to a few percent response corresponding operation, let the program does not make notebook battery power after, so that the battery itself revised its lowest power synchronization with curve of 0%
2. Charge and discharge: as above after setting, and then, based on the principles of full of it finished for battery charge and discharge, two or three times back and forth, the curve of the battery can be offset repair. Note: must let the battery charge, is the best way to shutdown filled a few hours or a night, and then pull the discharge, until the computer automatically fall off. And then you go back and forth at least two cycles
Method 2:
Battery is in use and charge the unstable factors will cause the loss of the capacity of the battery, but the decline is not caused by aging, so the appropriate calibration is to be able
to make this part of the lost capacity to recover. Therefore, it is necessary to carry out regular battery calibration, such as one to February.星座对对碰
Laptops such as Compaq and IBM have provided battery calibration in their BIOS or power management programs, so friends with these two brands can follow the instructions. For those who do not offer this feature, the user can follow the following steps:
1. Set screen protection to "none"
希腊字母发音2. Set the power usage plan to "always open" in Windows power management, and set the following closing device related menu to "never".
3. Set the "low power alarm" to 10% in the alarm TAB, and the operation is set as "no operation"; Set the "serious shortage alarm" to 3 % and operate as "standby"
4. Screen brightness to maximum
Confirm that all Windows are closed and all previous data is saved
6. Confirm that the battery is charging 80% of the time, unplug the power and all external equipment, if the screen brightness is automatically reduced, then please hit it to the brightest
