Laptop battery using tips

Should we remove the battery when the laptop powered by Household Electricity?

Do not remove the battery when using the AC adapter. If your area have no steady voltage or electricity, a sudden power failure happend when you at work, the work you have done lost and the machine may also burn motherboards without the battery protect.

Notice when charging

Usually used when the battery discharges to 10% of charge can be carried out, do not discharge to 0% every time before charging. In general the battery will be fully charged in 2-3 hours with machine shutdown , 4-5 hours with machine using. IBM’s notebook can not charge at 95% , COMPAQ laptop in about 90% before charging, this is designed to avoid the repeated charge and discharge damage to laptop. Requests depth of discharge once a month : discharge to 5% of the time , shut down the machine to re-charge. “Note - Do not let the battery completely discharged”. Remove the battery if do not use battery for a long time, please charge the battery to 50% before store.

Why do laptop batteries consumed when laptop turned off and cut off the power supply?

please see the following reasons:

1. The computer shut down, the laptop battery will provide power for RTC functions.

2. The power switch is not only the power line switch, but also the management control of power supply switch, the signal sent to the power switch function.

That is, the management of the power supply controller connecting the battery and power adapter has been a state power, so electricity consumption.

Micro-computer circuit to run, even send a message will consume battery power.

VAIO batteries, not just the battery, but also added to monitor the battery status (battery remaining capacity and charge and discharge current value, the temperature of the battery group, etc.) built-in micro-computer, and at regular intervals Send a signal to the computer functions.

Therefore, loading the battery in the computer will definitely consume electricity, even put out there will be a natural addition to discharge outside the electricity consumption. Thus, even cut off the power supply, battery consumption is normal.

 

I have been using my Pavilion dv9000 Battery for a year now, It has been an amazing experience working with it, but I have been always annoyed by the low battery  notification in vista.

When ever my laptop battery reaches to a critical low level it does not sound me an alarm rather it shows a pop up ( a balloon tip ) which indicates the low battery and normally I don’t pay attention this warning, and after some times windows hibernate the laptop automatically which I have configured myself so that I don’t loose my data and opened programs.

I would prefer to setup my windows to use the windows low Pavilion ZD8000 Battery  alarm system to sound an alarm, when it shows the low battery notification so that I can let .

Let’s see how can we setup and alarm in windows vista at the time of critical PA3383U-1BRS battery notification.

 

You will need to configure select the critical Inspiron 700m Battery alarm through sounds in control panel.

1. Open Start >> Control Panel >> Sound

2. Now Click on Sounds tab in Sound properties.

3. Download this alarm sound file from here and place in a separate folder, Click on the browse button and locate the downloaded alarm file.

4. Click Test button to listen to the alarm sound, and click OK

Now when ever your laptop reaches low Toshiba PA3399U-2BRS battery level it will sound the loud alarm before it hibernates or shutdown

How to replace battery cells inside laptop battery

In the last article, we have introduced “how to hack dead laptop battery” to our readers, but it is too simple. Now we write a detail article about ” how to replace battery cells inside laptop battery”.

At present, there are many articles about “how to purchase and use laptop battery” on the network , but there are too less article about “how to repaire laptop battery”. For this reason, we decided to write a article about,laptop battery repair industry to help notebook users know what to do when laptop battery broken.

To notebook the battery is very important as the mobile work. The notebook become to desktop without laptop battery. There are battery cells and protection board in laptop battery inside. The batteries cells supply the power and the proctection panels protect the board safety when charging. Battery cells are consumable items, the capacity reduce in each using, which directly determine the quality of notebook batteries.

Notebook battery life short suddenly , cant work, laptop battery down suddenly (such as: battery capactiy suddenly reduce from 40% to 10% when working), laptop battery cant be fully charged,notebook battery cant be fully discharged (the notebook closed when the battery power state in 40% or more), the above cases may be caused by batteries capacity declining or batteries cells damage. Of course, there may be due to damage of the protection board, but this possibility is very small.

laptop battery cells

If you find that above failure happened to your notebook, it is necessary to check your laptop battery in laptop battery maintenance business. Now, let me introduce the whole process of laptop battery cells changing (for example Thinkpad T40 battery) .
First, we use professional equipment to detect the cause of the malfunction. There are many types equipment of Battery Fault Detection, such as: Texas Instruments products, MAX products, Ateml products, and even some personal home-made products. Most we use the commonly Texas Instruments (Texas) EV2300

Use professional equipment and related software to detect the cause of the malfunction

Once detected 92P1101 battery cells faulty , we are prepare to change the batteries cells for notebook battery.

Before the battery cells changing, We would like to tell you about the structure of the notebook battery.

The 92P1102 laptop battery are made up of three parts: batetry shell, battery cells and protection board.

In general, notebook battery can be divided into three parts: the shell, batteries and protection board。

Battery shell

Battery shell. That is notebook battery casing. There are different three types: type, ultrasonic bonding and adhesive bonding type.

08K8193 Batteries cell

Batteries cells group, that is, combination the batteries cells together in parallel and series connection. In accordance with the parallel, in series of different combinations can be divided into: 2 parallel and 3 serial connection (the most common), 2 parallel and 4 serial, 2 parallel and 2 serial, 3 serial and 3 parallel and 3 parallel and 4 serial (relatively rare).

Protection panel

Protection board, which is based on an agreement SMB1.1 circuit board, with power management functions and charge-discharge management.
Protection board, which is based on an agreement SMB1.1 circuit board. There are three chips on it : battery Measurement management chip, charge and discharge management chip and serial EEPROM memory chips

On positive plate : measuring management chip and charge-discharge management chip

The plate back has a serial EEPROM memory chips

Decrypt and unlock the protection board are two different works. Before you go into the battery management system you must decrypt the protection board, unlock the battery management system in order to change the parameters of the battery and use of information. If you only change batteries cells without unlock, you can not achieve satisfactory results (for example: the battery can only charge to the state “the last full charge capacity”, the battery maintenance management information will be displayed the charged number)
We use professional equipment and related software to unlock and decrypt the protection board. Of course, you must choose the appropriate equipment by 92P1087 battery management chip design.

If the protection board hardware damaged , we would also use oscilloscope, multimeter and logic analyzer

After the deal with the batteries protection board , let me introduce the method to choose the right cells. We must use sub-meter cabinet and the internal resistance to check batteries capacity resistance, separation voltage, select out all specs of parameters for comparison with similar groups. Also the thinkpad R50 battery
thinkpad T41 battery
thinkpad T42 battery
thinkpad T43 battery is the same battery cells.

Sub-capacity cabinet

Select the similar cells to make a battery group

Then we will use the spot-welding and Nickel sheet to joint the batteries cells together.

After unlock and decrypt the protection board, connect the battery cells group. We can assemble the shell protection board and cells together.

During the assemble, you must take high attention. The steps is also suitable for IBM 40Y6795
40Y6797 40Y6799

After doing the above steps, the battery cells changing is compeleted. The repaired battery quality is the new battery in most function, so you must calibrate it first. Generally, you should fully charged in 1o hours then full discharge it 2-3 times.
