如何修复笔记本电池（How to fix a laptop battery）

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 discovery 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:

/ / / 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 can 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

Above is my point of the battery deep discharge lossless

recovery, for reference only.

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

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.

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"

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

OK, you can go to bed,

Discharge end of the notebook will automatically shut down,

then plug in the power supply for notebook, attention must be

completely filled with such as again after boot, and then the

restoration of power supply scheme to calibration before

setting.

Repair laptop battery methods and maintenance

(1) cause of battery damage

Laptop battery life is long, often charge the battery, even show

the battery has been damaged, the specific performance is the

internal resistance, in charge of both ends voltage rise

relatively fast. This can easily be determined by the charging

control circuit as already full and the capacity naturally

decreases. Due to the large internal resistance of the battery,

the voltage drop in the discharge is large and fast, so it is

easy to mistake the system for insufficient voltage and low

power. In case the battery working time is relatively short,

corresponding measures should be taken.

(2) refresh the battery's discharge time with the battery

refresh program

Most branded laptops have a battery refresh program that we can

use to repair the battery. For example: a IBMThinkpad390/262650

type notebook computer, the match for the nickel metal hydride

batteries (Ni Mh battery, due to improper charge and discharge

at ordinary times, lead to the battery discharge time is more

and more short, only less than 5 minutes, if the laptop to go

out to work, is very inconvenient, is there any way to restore

the battery discharge time?

In view of the above situation, we can refresh the battery with

the battery refresh program introduced by IBM, so that the

discharge time can be restored. The specific method is as

follows.

(1) the use of alternating current (ac) to power a laptop, the

first to ftp:///pub/pccbbs/mobiles/ isbr01ww.

Exe download TP390 provided by the IBM / 390 e / 390 x series

laptop battery refresh program.

(2) restart the computer, press F8 to the boot menu, and select

the safe DOS mode.

(3) enter the directory where the file just downloaded, execute

the battery refresh program isbr0lww, exe, read the warning

information, insert the floppy disk as required, and then press

enter to perform the self-decompression operation.

(4) use this floppy disk to guide the computer, the screen

prompt information.

(5) when the ac power is unplugged, the program automatically

discharges the Ni - Mh battery. After the discharge is completed,

the system will be automatically closed.

(6) due to the high temperature of the battery, the battery

should not be switched on immediately, so that the battery will

be cooled for a while, and plug in the ac power.

(7) using a floppy disk to boot the computer, the Autoexec. Bat

file automatically runs the refresh program and asks if the user

is doing it. After you select yes, press enter.

(8) at this time, the refresh program starts to refresh the

battery, and its process is very fast. When it returns to the

DOS prompt A: >, the refresh has been completed.

(9) turn off the computer and charge the battery until the

indicator turns green.

(10) repeat the procedure three times to get the best results.

In addition, many lithium battery failures are caused by the

failure of a section of the battery pack in the battery pack,

which can't be avoided. Because the core of each cell can't be

exactly the same,

After a long period of time, some of the quality starts to age

slightly, and destroys the entire (tandem) discharge curve.

Interested and capable readers can try to open the battery pack

and, with the help of the multimeter, can quickly find the

broken core (abnormal voltage). If the conditions permit,

replace the qualified products according to the corresponding

parameters of the core-core.

IBM notebook battery to repair actual combat

My IBM2611 laptop, which has been used for more than three years,

has not been changed. In the last six months, the battery power

has gone from bad to worse. Today, it's only twenty minutes to

take a test of the watch. I want to buy a new piece of work,

but I didn't expect to get the blue express accessories. I pour:

R2611 lithium battery 850! My machine is worth a few dollars

now? Go to the second-hand market ask, a battery sells 350, say

to protect a month, but after a month?

There is no way to drive the cat online, and go to the Internet.

On every laptop, BBS or website, there are a lot of

introductions about the core of the old battery, and the dealer

who specializes in it. A battery can range from 10 to 25 yuan.

But like the IBM battery I used, there are eight nickels of metal,

and at least you'll have to spend 100 yuan. Although 100 pieces

is a small dish, in case change is not good, even the original

20 minutes also have no. You can't take that risk.

At this time, there is a superior on BBS to give me an idea:

the memory benefit of nimh battery is very obvious, it is better

to try the discharge first, then plan. I'm looking for a

multimeter to measure the positive and negative side of the 2611

battery, and the interface on both ends of the battery is

positive and negative. A voltage of 10V, it seems that the

voltage is normal, after the complete discharge, the

possibility of battery recovery is still very high.

Now, discharge the discharge. Turn off the ac, start the

computer, watch the power display: 98%, open Winamp listen to

Mp3, listen for 20 minutes, the computer prompts to save the

job. The current charge is 1%. The computer soon went dormant.

Shutdown, remove the battery, a test voltage, strange: 10V! No

matter, he found two emergency light small bulbs, 6 v put a plug

in the power, the abnormal light bulb, and then put it the first,

after nearly two hours, light finally destroyed (later found

to be burnt out). Install the battery, connect the ac, power

up, power management display is charging, 5 minutes left and

right time, unexpectedly charge 60%! How is that possible

Almost half an hour, the electricity was full. Start the

"Battery Bar" test to show the power of 100%, disconnect ac,

and Battery Bar shows that the remaining power is 98%, and the

estimated time of use is 3 hours and 10 minutes. "I said to

myself," is that all right? It's Easy!" Start the Winamp listen,

but within ten minutes, there was a call! "The battery is low,

please replace the battery." The battery is shown at 3 percent,

and then the computer sleeps. The battery only took ten minutes

to remove the battery, a test voltage, or 10V. It seems that

the battery can't be released, so it can't be connected with

the light bulb. Five minutes or so, the lights went out, the

voltage was measured, it was still 10V. How do you get it? Put

it on. It's like a little bit of electricity. Look at the light

bulb and burn it! That's not going to work.

I load the battery, disconnect the ac,

Start the computer, even start! The electricity is still 3%.

Then there was the quick alarm, and the computer turned to sleep.

Now, I was lost in thought.

Since the battery is still able to start the computer, it's

enough to say that the battery is very high. The switch to sleep

soon after it was started, indicating that the battery was not

running smoothly, and that it was not running out of electricity.

The rest must be enough to start the computer. Try it this way:

the computer is asleep, click on the mouse to activate it, and

after a while the computer activates it again when it's asleep,

and the effect might be better. In this way, the computer wakes

up every three minutes. After 45 minutes, the computer couldn't

wake up. Remove the battery, this time the voltage is less than

5V, then connect the 6V bulb, continue to discharge until the

lamp is out, should be said that the discharge succeeded.

Reload the battery, connect the ac, and turn on. Power

management display: charging, power 1%.

I turned on Word to write this article, and found that the

battery display remained at 1%, but felt the battery, a little

hot, and should be charged. Wait for one hour and 50 minutes,

and the charge is 43%. I can't wait. I'll test it first.

Disconnect the ac and start the Battery MaxiMiser Wizard to set

the Battery to moderate energy saving (CPU speed: medium CPU

speed medium LCDevel 7 screen is brightest), start to measure

Battery usage time, and the background running program Winamp,

word. Cpu utilization is 100%.

The power release is relatively smooth, starting from 43 to 37

percent of the time, from 37 percent to 31 percent, 9 points

from 31 percent to 25 percent, and 10 points from 25 percent

to 3 percent. The battery actually USES 30 minutes and consumes

40% of the battery. In proportion, the battery should be full

of electricity for about 80 minutes. At this point, the battery

announces the perfect return.

The result is really surprise me, not think with this incredibly

can approximate the original methods is to make my old battery

on a second, it also shows the IBM laptop batteries in a sense

of quality. If you have the same IBM laptop as I do, you can

try it.

Laptop battery repair software (BatteryMon)

This is special repair some old does not remove the battery with

alternating current (ac), and failure modes of the battery in

a short period of time, there are instructions, tried a SONY

laptop, 15 minutes to an hour and a half, the text 2 hours, with

rising to kill poison, hope useful for everyone.

How to use it: unpress, when the laptop starts charging, run

and start directly. It will show up after a while. Then turn

off the power, pull out the laptop plug, turn on the computer,

and run the program. Some time after the discharge end, wait

until the computer automatically shut down, and then plug in

a laptop power supply, boot to run the program, charging status,

again after the shutdown, pull out the power and the boot

operation, application showed that the discharge, wait until

to turn it off. The above two rounds, generally 2-3 rounds are

a course of treatment, so the battery basically responds to the

state.

Principle: for technical reasons, the battery still has memory,

Lazy people generally love to remove plug without battery, so

that every time lead to not start charging the discharge, due

to the memory of the battery and battery internal control

circuit of the "intelligent", the battery detection circuit

will think the battery energy is in your charge to end this short,

then has been under the circulation, battery control circuit

is the battery capacity is defined as a low value. This software

allows the detection circuit to suspend operation without error

memory, and refill the more real "charge"

Maintenance of laptop battery

1. When there is no external power supply, if the working

conditions of the time are temporarily not available in PCMCIA

slots, it is recommended to remove the card to extend the

battery life.

2. Room temperature (20-30 degrees) is the optimum working

temperature for the battery. The operating environment of high

temperature or excessively low temperature will reduce the

battery life.

3. When using a laptop in an environment that provides a stable

power supply, it is not correct to remove the battery to extend

the battery life. In the case of asustek's laptop, when the

battery is full, the charging circuit in the battery shuts down

automatically, so there is no charge.

4. It is recommended to conduct a battery power correction

action on average three months.

Minimize the number of batteries you use

The number of charge and discharge of the battery is directly

related to the life span. Every time the battery is charged,

the battery will move forward. It is recommended that you use

external power source,

6. Remove the battery when using external power source.

Some users often plug in a power supply multiple times a day,

and laptops are equipped with batteries, which can be more

damaging to the battery. Because each time the external power

is plugged into the battery, the battery will naturally turn

to life.

7. Charge and avoid charging too long after running out of power

Whether your laptop USES lithium or nimh, make sure you run out

of battery power (less than 1%), which is the best way to avoid

memory effects. Lithium also has memory effects, but its memory

effect is smaller than that of nimh.

8. Precautions should be used

In peacetime use, should prevent exposure, prevent dampness,

prevent chemical liquid erosion, avoid battery contact and

metal contact, etc.
