Typically, after charge and discharge for 300 times, the performance of laptop battery will be decreased, but many people prefer to buy expensive original battery but not to buy OEM batteries.
I have a friend like this around, I asked him why, the answer was: fear of problems. Expensive laptop, he would buy an original battery which has quality warranty, but will not buy the OEM batteries for fearing the bad quality cells.

This is a very typical answer, and if the purchase of low-quality batteries hurt his beloved notebooks and even cause accidents is indeed a depressing question. This will be completely disassembled an original IBM battery with a replacement OEM battery, the facts speak for themselves, to check that how is the quality of third-party replacement OEM battery. At the same time, we will introduce in the text interspersed basic knowledge of the battery and circuitry, specifically dedicated to love yourself DIY classmates.

Two batteries to be dismembered , IBM OEM battery and the original 6-cell IBM laptop batteries

Prior preparation, we need two batteries, wallpaper knife 2, the word screwdriver, a pry a piece.
Now all ready, hands split!.

Original IBM laptop batteries will be the first to be mutilated.

Battery closed beta is the gap where the greatest and there is no alignment, we will open it here.

With a wallpaper knife gently tilt here can, careful not to plan too deeply to avoid injury to the batteries.

Pry out from here, hardly managed to open the battery cover.
It is lifted above the state, we can see that this battery of six batteries and control circuitry arranged look. Classified according to cell media, which are lithium-ion laptop battery. Light weight, large capacity, no memory effect and so on.
Because the lithium-ion battery is almost no “memory effect” and does not contain toxic substances, etc, and now most of the more digital devices are used to make lithium-ion battery power, its price is relatively moderate, high energy density, its capacity is with the weight of the nickel-metal hydride batteries 1.5-2 times, and have low self-discharge rate.

This battery is a relatively common structure: laptop battery appears to be something of a box, which is in fact a number of “batteries” composed by series and parallel, in general, notebook batteries are used 18650 or 17670 batteries, the main because the two batteries have larger capacity, smaller size, are likely to cause the shape of the battery needed. We are now open for IBM battery is 18650, of which 18 representatives of diameter 18mm, 65 represent a high degree 65mm, Sanyo products.

Here the humble little piece of circuit board is also the power supply system of the laptop are crucial to do with. Because the basic lithium-ion batteries are 3.6V or so, the two batteries in series to double voltage; parallel voltage unchanged, but the capacity has changed twice. Such as IBM T series, capacity 4400mAh, voltage of 10.8V, the two values is the string from the six batteries and combination.

The information of original battery cells is not written in the skin, but on the printed batteries metallic cavity, the peeling skin to see.
Sorry about that, although the Sanyo is the batteries in is a good brand, but the piece of IBM original battery is only used Class B battery cells.

Well, we have made clear of IBM original battery internal structure, here we start dismantling OEM replacement battery.

This is the internal structure of the 9 cells OEM battery

From the exterior, it’s s similar to the original IBM laptop batteries.

The battery cells of this OEM battery is Samsung 18650, purple, marked ICR18650-26, in front of a model, the back 26 that a single volume 2600mAh, can be regarded as one of Samsung’s best cells.

Name: Samsung Li-ion rechargeable battery
Model: SAMSUNG ICR18650-26
Nominal Capacity: 2600mAh
Nominal Voltage: 3.7V
Diameter: 18.25mm
Height: 65.00mm
Weight: 50g
Density: 520Wh / I, 199Wh/kg
Charging method: constant current constant voltage (4.2V)
Maximum charge current: 1CmA (2400mA)
Maximum discharge current: 2CmA (4800mA)
Discharge Temperature: -20 ° C ~ +60 ° C
Charging time: 3hrs (Standard) or 2.5hrs (Rapid)
Resistance is less than 65 cents in Europe.

It should be said, although Samsung battery cells is not known as well as Sanyo, but at least the top Samsung battery cells is much better than the Class B Sanyo batteries.

Therefore, unless you have enough money to purchase original IBM battery, or it is recommended to buy compatible OEM batteries, it’s sufficient for most everyday’s use.

ASUS EPC10008HA and HP Mini311 difference in battery life are close to the area 1 hour.

Text that Microsoft wants Windows 7 in the Internet market is better than the Windows XP, “but the result does not seem very good.”

Testers pointed out that although the same hardware test environment, but Windows7 WindowsXP and support in different drive, in addition, the online system, the manufacturer driver for Windows7 support and updates are relatively backward, so such an outcome, “do not have to much of a surprise. ”

Testers also noted that the test results do not mean that Windows 7 WindowsXP in performance than the worse, because Windows7 in support of family entertainment, with better performance, of course, the Dell E6400 Battery‘s usage requirements higher.

Microsoft recently published a report entitled “win7 Power Management” of the 14 white paper describes Windows 7′s power management technology to reduce power consumption. Windows 7 if you want to know how the power of the white paper will give you the answer. If you only want a simple quick look at, the following will tell you the main means of energy-saving Windows 7.

1. Free energy resources

When a computer starts, not always running at full load, so there will be a lot of idle time, idle time, power consumption has become an important power management technology. In win7, the idle power consumption when the effective improvement of the hardware when a certain period of time does not work will enter a low power state has to save battery power. Including the CPU, hard drive, memory and network elements have adopted this technology. For example, a full power run power 35w of the CPU power consumption at idle is almost 0, only this one will be able to save power.

2. Through the trigger to start the service

System services are typically a time when the system starts with the start, and then resides in the background waiting for calls. In Windows 7, the part of the system service is only triggered by some event will start, such as inserting a device or change the IP. This reduces the long-running background process in the number of services.

3. Enhanced processor power management

win7 in integrating the latest power management technology that allows Windows 7 based on the current load conditions and performance requirements to dynamically adjust CPU performance.

4. Adaptive display brightness adjustment

Microsoft said, usually 10-15 minutes, if no operation, the monitor will automatically shut down. However, in practical use there will be more short-term non-operating condition, in order to better energy efficiency, the technology will reduce the display’s brightness. In addition, it could use some sensing devices to adjust the brightness according to ambient brightness display.

5. Low-power audio

win7 will support Intel’s low power HD audio specification, it allows codec into low power state. win7 also supports selective suspend technology to shut down idle equipment, such as microphones and cameras such USB devices.

6. Timer integrated

The current processor instruction address space through the use of free time to save energy, but most of the energy-saving technologies need a certain length of time to get free energy saving effect. The adoption of this technology for Windows kernel at the same time, the original end and focus more dispersed multiple timers, disposed of in a short time, thus increasing the processor’s idle time.

In addition, when the laptop in case of battery, win7 non-critical background processes will reduce the frequency of activities.

7. Bluetooth devices to improve power

When win7 detected Bluetooth devices in a low-power state, they will be temporarily closed, or “selective suspend.”

8. Network equipment to improve power

win7 the radio network controller for low-power mode compatibility has been enhanced, the wireless AP devices support only low-power mode is enabled only when the situation. Vista because it can not detect in advance whether to support low-power mode, it can cause sudden interruption of the wireless network connection. win7 will prevent that from happening, before entering the low power mode will first test whether to support the model of wireless AP.

9. Typical applications of the optimization program

In addition to the above listed improvements, Microsoft also turned to some specific applications, including search, browsing and small game without networking. The following is optimized DVD playback program part of the occasion:

Without affecting the playback performance of the premise of maintaining low power mode to CPU

By changing the structure to improve the desktop window manager and GPU power consumption

Intelligent data caching can reduce the drive speed

The above is win7 9 in the power management important improvements, compared to the previous system can save more energy. In addition to these improvements, IT professionals also diagnosed with power management that may affect the power efficiency to find the problem.

Well-known Internet-virus software company KASPORSKY Kabajisi recently issued a warning, please, please beware of notebook virus l called Blue Eyes is widely disseminated through the Internet! The virus can attack the laptop battery, notebook battery fire attack will lead to even explode!

It is reported that this “blue eyes” is harmless for the common hardware and software completely , it is disguised as a feedback information packet, by TP / IP network to send interactive mode. Since the packet itself does not have any offensive capabilities, the current firewall and antivirus software can not be filtered or alarm.

But for laptop users, this virus is very dangerous. When the laptop battery is fully charged, it will send a software signal to the transformer, to remind the charging end, into float mode. It is this signal to activate the virus, blue eyes, it will retain this information and issued a “quick charge” signal. Then transformer will accelerate as the laptop battery, just a few minutes will result in laptop battery charge, and thus damage the laptop battery or even explosion. At present in Russia and Europe have been a spate of laptop batteries burning incident, the Dutch bank’s office notebook case of spontaneous combustion in standby, but it is unclear whether because the “blue eyes”, then.

Warning said the current anti-virus software can not resolve by this virus, but a few are given to avoid damage to the concrete measures laptop battery:

1. Do not start a state charge, “blue eyes” virus work in the WINDOWS system environment does not work in DOS or shutdown;

2. The work of the state is best not to use an external power supply, use only the battery, which can persist for some 1-2 hours of laptop models is undoubtedly bad news for users;

3. Any attention to laptop batteries margin shows that the rapid increase in power if found, should immediately unplug the external power supply or off;

4. When they find the keyboard too much heat, you should check the battery remaining capacity in a timely manner.
