Lenovo L15L3PB1 Laptop Battery Installation Instructions

Laptop batteries are generally divided into internal and external. The external battery is usually located under the computer. Turn over the clip that holds the battery and remove the battery. This battery is the easiest to remove. The following is a brief description of the process of removing the built-in battery.

The shape of the built-in battery can be divided into square and cylindrical.

The computer itself is very thin and is a square battery, usually located under the computer. Cylindrical batteries are usually located above the interface between the computer body and the display. Today, more and more new notebook computers have become ultra-thin portable computers, and built-in batteries have become a trend.

1. Remove all screws from the computer back cover.

2. Clip the gap on the back cover with your nails, then cut the gap with a card or screwdriver to separate the back cover from the host.

3. Open the back cover and locate the battery.

4. Remove all screws used to secure the old battery.

5. Use your nails to pull the battery cable connector out of the cable port and carefully remove the cable connector from the cable port. Do not use excessive force or urgency.

6. After removing the old battery, first check whether the new battery cable connector is compatible with the corresponding screw hole. After confirming that it is correct, start installing a new battery.

7. First, gently insert the battery cable connector into the cable port. Don’t use too much force.

8. After installing the cable connector, tighten each screw.

9. After installing the battery, close the back cover and tighten the screws.

Samsung EB504239HU Mobile Phone Battery Installation Instructions

Before replacing a new battery, make sure that the phone battery is an old battery that is easily removable or a built-in fixed battery.

Traditional batteries are usually not removed.

Steps to replace the battery inside your phone.

1. Since the adhesive is already attached to the built-in battery, please heat the back cover of the phone for a few minutes to loosen the adhesive.

2. Using a removal tool, gently pry the slit on the back cover and secure it with the card. Next, secure the suction cup to the back cover and pull it out. While cutting the slit with the card, drag with the suction cup to keep the back cover open.

3. The battery metal interface and the phone main board are fixed, so after opening the back cover, you need to hold the back cover to continue operation.

4. Locate the battery. Remove the screws that secure the battery.

5. Remove the battery metal connector with tweezers. Use a utility knife to remove the tape toward the battery fixing position. Don’t use too much force. Also, be careful not to scratch the battery. If scratched, the battery will explode and burn.

6. After cleaning the tape, make sure that the battery’s metal connectors and screws have been removed. You can remove the old battery.

7. Make sure the metal connector on the new battery matches the original battery. Align the battery’s metal connector with the insert. Align the tape with the battery.

8. After fixing the battery, screw on and fix it.

9. Close the back cover to complete the installation of the phone battery.

Poor heat dissipation, troubleshooting motherboard

As the core of the computer, the motherboard has a high probability of failure due to its circuit integration. Poor heat dissipation, capacitor breakdown, etc. will cause the entire system to be paralyzed. Most people think that as long as there is a problem with the motherboard, it can not be repaired by conventional methods. Therefore, once a computer motherboard fails, it is often a new thing.

In fact, although most components of computer motherboards are highly integrated chips, there are also resistors, capacitors, diodes, and triodes commonly used in ordinary circuits, especially some high-power tubes often pass large currents, so Due to the large heat generation and the size limitation of the computer motherboard, it is impossible to make the heat sink very large, especially some cases are small and the heat is not easy to dissipate. Therefore, these high-power tubes sometimes work at temperatures exceeding their maximum operating temperature for long-term use It is inevitable that problems will occur. Next, I will briefly introduce the main board failures and troubleshooting methods I encountered in the computer. Friends who have encountered similar failures may wish to learn from my repair experience. Maybe they can restore your computer’s power and save you Many expenses.

First, the computer fails to start, the motherboard dust is too fierce.
Failure performance: The assembled compatible machine often fails to start recently, and occasionally it can enter the system is also frequent crashes, affecting normal work and entertainment.
Fault summary: Dust is the invisible killer of the computer. The accumulated dust prevents heat dissipation, easily damages components, and can cause short circuits in wet weather. Dust also has a great impact on the mechanical parts of the computer. Therefore, it is extremely important to regularly give love to the machine.

Second, poor heat dissipation, leading to damage to the motherboard capacitor troubleshooting
Failure performance: After the assembled compatible machine continued to play the game for seven or eight hours, all of a sudden the screen became black and did not respond. After pressing the power button of the chassis again, the machine still did not move.

Fault summary: Due to the large number of motherboard manufacturers, the materials and workmanship are uneven. Many second-tier motherboards of different brands not only do not work hard, but they are not sufficient in materials. In addition, the heat dissipation environment is not good, which can easily lead to Capacitors or other components are burnt out. Therefore, when choosing a motherboard, you must choose a product from a first-tier manufacturer. In addition, even if the motherboard is made with sufficient materials, if it is used in a high temperature environment for a long time, the capacitor element will burn out over time. Everyone must pay attention to do a good job of heat dissipation to prevent accidents.

Simple judgment method of motherboard failure

The motherboard is the bridge responsible for connecting computer accessories, and the stability of its work directly affects the normal operation of the computer. Due to the many and complex components and circuits it integrates, there are relatively many causes of failure.

The determination of the motherboard failure is generally done by gradually removing or replacing the board cards (memory, graphics card, etc.) connected to the motherboard, and after troubleshooting the possible problems of these accessories, the target can be locked on the motherboard. In addition, motherboard failures often appear as failures that are difficult to visually judge, such as system startup failure and no display on the screen. In the following, the author only introduces some common and easy-to-operate fault judgments. For some circuit and electrical fault problems, due to the need to resort to professional maintenance diagnostic tools and the author’s ability is limited, I cannot list them, and apologize here.

1, related to the motherboard driver

Loss, damage, and repeated installation of the motherboard driver will cause the operating system to fail to boot or cause the operating system to malfunction. Open the “Control Panel-System-Device Manager” in order to check whether the items in the “System Devices” are available. Yellow exclamation mark or question mark. Delete all items marked with yellow exclamation mark or question mark (you can operate in “safe mode”), reinstall the driver that comes with the motherboard, and restart. For example, the motherboard using Intel chipset needs to install the “Intel Chipset Software Installation Utility” motherboard driver, and the motherboard using VIA chipset needs to install the “4 In 1” driver to get better stability and compatibility.

2. Poor contact, short circuit, etc.

The area of the main board is large, and it is a place with a lot of dust. Dust is likely to cause poor contact between the slot and the board. At this time, we can blow air against the slot to remove the dust. If the contact is caused by the oxidation of the socket pins, you can fold the hard white paper (smooth surface facing outward), and insert it back and forth to wipe it. In addition, if dust is attached to the thermistor used to detect the temperature of the CPU in the CPU socket or to monitor the temperature in the chassis on the motherboard, it is likely to cause the motherboard to identify the temperature incorrectly, which will cause the protective failure of the motherboard. Also need to pay attention when cleaning.

When disassembling or disassembling the case, the conductive objects such as small wires that are accidentally dropped may get stuck between the components of the motherboard and cause a short circuit phenomenon, which will cause a “protective failure”. In addition, check whether the main board and the chassis bottom plate are not equipped with small copper pillars to support the motherboard, whether the motherboard is improperly installed or the chassis is deformed to directly contact the motherboard and the chassis, so that the power supply with short-circuit protection function automatically cuts off the power supply.

3. Related to the motherboard battery

When encountering: the computer can not find the hard disk correctly when the computer is turned on, the system time is incorrect after booting, and the CMOS settings cannot be saved, you can first check whether the motherboard CMOS jumper is set to clear the “CLEAR” option (usually 2-3), If so, please change the jumper to “NORMAL” option (usually 1-2) and then reset. If it is not a CMOS jumper error, it is most likely caused by a damaged motherboard battery or insufficient battery voltage. Please try another motherboard battery.

4. Compatibility issues

If you encounter a compatibility issue between the old and new things due to a bug in the motherboard design or an upgrade accessory, you can download the latest BIOS of the motherboard to refresh it after excluding the BIOS setting problem. In addition, I also encountered compatibility issues caused by upgrading the operating system and later determined that the motherboard BIOS was outdated.

Trick one: Clearing the CMOS settings can also solve some “inexplicable” failures, you may wish to try.

Tip 2: When the installed hardware is not recognized by the operating system, set the “PNP OS INSTALLED” item of the CMOS setting to “YES” or “NO” and try.

5. The poor cooling effect of the motherboard’s north bridge chip caused

Some motherboards eliminate the heat sink on the Northbridge chip, which may cause the chip to dissipate heat effectively and cause the system to freeze after running for a period of time. In such a case, you can install your own heat sink or add a case fan with good heat dissipation effect.

6. Caused by failure of motherboard capacitance

The aluminum electrolytic capacitor on the motherboard (usually around the CPU socket) uses an electrolyte inside. Due to time, temperature, quality and other reasons, it will cause “aging”, which will cause the motherboard’s anti-interference index to decline. Affects the normal operation of the machine. We can buy capacitors with the same capacity as the “aging”. After preparing the soldering iron, solder wire and rosin, replace the “aging”. In addition, the loss of tools when disassembling the computer may accidentally smash the capacitor, which should also be checked and removed.

Damaged BIOS

Due to BIOS flash failure or BIOS damage caused by CIH virus, if the boot block (referred to as BIOS Boot Block in Award BIOS and Flash Recover boot Block in Phoenix BIOS) is not damaged, you can use the homemade boot disk to refresh BIOS (for the specific method, please refer to the related article on this site, which will not be repeated here). If the boot block is also damaged, you can use hot plugging method (very dangerous) or use a programmer to perform safe repair.

Computer optical drive maintenance

The CD-ROM drive of a laptop is a very delicate component, coupled with its high frequency of use, the lifespan is indeed very limited. As a result, many businesses have a much shorter warranty on optical drive components than other components. In fact, the laser head is mainly affected by the life of the optical drive. The life of the laser head is actually the life of the optical drive. To extend the life of the optical drive, you should start with the maintenance of the laser head. There are ten methods:

First, keep the optical drive and disc clean
The optical drive uses very precise optical components, and the optical components are most afraid of dust pollution. Dust comes from the entire process of loading and unloading the disc. Whether the disc is clean or not is directly related to the life of the disc drive. Therefore, the disc should be cleaned before it is loaded into the drive, and unused discs should be properly stored to prevent dust pollution.

2. Regular cleaning and maintenance of the laser head After using the optical drive for a period of time, the laser head must be stained with dust, which will reduce the reading capacity of the optical drive. The specific performance is that the reading speed of the disc is slowed down, the display screen and the sound appear mosaic or pause, and in severe cases, the sound of the optical disc frequently reading the disc can be heard. These phenomena can damage the laser head, the drive motor and other components. Therefore, users should regularly clean and maintain the optical drive or ask professional maintenance.

III. Keep the optical drive horizontally?
During the use of the machine, keep the optical drive horizontally. The reason is that the center of gravity of the optical disc changes due to imbalance during rotation, which can reduce the ability to read the disc when it is slight, and may damage the laser head in severe cases. Some people use computer optical drives to install software on different machines. They often take the optical drive off and take it with them, and even carry it with them, which is very harmful to the optical drive. The danger is that the optical components and laser head in the optical drive are subject to changes due to vibration and oblique placement, which causes the performance of the optical drive to decline.

Fourth, develop the habit of taking disks in time before shutting down
一旦 Once there is a CD-ROM in the CD-ROM drive, not only will it take a long time to read the disk when the computer starts up, but the CD-ROM will always be at a high speed. This not only increases the working time of the laser head, but also makes the motor and transmission components in the optical drive in a worn state, which virtually shortens the life of the optical drive. It is recommended that users develop the habit of removing the disc from the optical drive in time before shutting down.

Fifth, reduce the working time of the optical drive In order to reduce the use time of the optical drive to extend its life, users of computers can use the hard disk space to allow virtual disks to be stored on the hard disk. Such as teaching software, game software, etc. are stored in the hard disk, so that it can run directly on the hard disk in the future, and has the characteristics of fast speed.

26. Opening and Closing the Disk Box Correctly Regardless of the type of optical drive, there are buttons for ejecting the box and closing the box on the front panel. Using this button is a conventional method of properly opening and closing the optical disk box. When pressing the keys, do not press your fingers too hard to prevent the keys from getting out of control. Some users are accustomed to pushing back the disk box directly with their hands. This is a damage to the drive gear of the optical drive. It is recommended that users overcome this bad habit.

7. Use the program to open and close the box
Use the program to switch the disk box. This function is available in many software or multimedia playback tools. If you right-click the CD-ROM drive letter in Windows, there is also an “Eject” command in the pop-up menu to eject the CD case. It is recommended that computer users use software to control the opening and closing of the disk box as much as possible to reduce the failure rate of the optical drive.

8. Careful maintenance
Because all the components in the optical drive are very precise, the user must pay attention to the methods and methods during disassembly and installation of the optical drive, and pay attention to recording the original fixed position. If you are not sure, ask professional maintenance personnel to disassemble and repair. Especially when the laser head is aging, it is necessary to adjust the driving power to increase the power of the laser tube, and it must be debugged by a professional maintenance person to prevent it from being adjusted too large, which will cause the laser head to burn out.

Maintance of Notebook PC LCD

The screen of a notebook is very important, so everyone wants to protect it, so is adding a film to protect it well? How can I make the screen of the notebook as long as possible? The screen cost of the notebook accounts for the entire notebook cost It’s a big part and it’s easily damaged, so we should take good care of it. Adding a protective film can play a certain protection role, you can choose some brand-name products, this effect will be better.

A LCD screen, the normal use time, that is, about 5 years, as time goes by, the screen of the notebook will become more and more yellow, which is the phenomenon of aging of the lamp inside the screen. So how to make the aging time go back as far as possible? Here are a few tips to make your screen last longer.

First, usually reduce the possibility of the screen being exposed to sunlight. Use it during the day, and try to pull up the curtains to prevent the screen from being too hot after it is exposed to sunlight, which will accelerate the aging.

Twenty-two, do a good job of daily cleaning. In daily use, it is in close contact with the notebook, so that various stains will inevitably be left on the screen, so we must do a good job of cleaning the notebook screen. You can use a 3m magic cloth to wipe it, and the general dust can be directly removed. , But for the more stubborn, you need to use a little gas. But be careful, cut off all power to avoid leaks or water.

Third, reduce the brightness, which can effectively extend the service life. It is usually enough to open 1-2 divisions during the day, and 2-3 divisions at night. When you turn on the power again, there are sometimes default options. The screen is particularly bright. Be sure to recall it.

24. Remember to turn off the screen when leaving for a long time. If you have something to leave, you must remember to turn off the screen. The shortcut key is Fn + F3, so that the screen will not light up.

Fifth, do not point at the screen with your hand, pen tip, or other objects. If you pay a price, it is easy to cause bad points, and you are late.
