Some people will confuse that there is just only one connector on the back of its LCD screen, while the new screen he bought has two connectors. Is new screen suit for his laptop? Does wrong screen he bought? Now, let us have a look of it.

If the new LCD’s power board may not as same as that of old LCD, and moreover, you will find that near the connector which is used to connect the LCD to your notebook, there is an extra and smaller connector. Do these differences will affect your laptop? What is it used for?

The extra connector is used in the touch screen laptops to connect with digitizer or as a data port to update the LCD internal BIOS. So if there is no digitizer for you, there is no need for you to use extra connector. The new screen with extra connector will work well with your laptop, and what you need do is just leave it alone.

Today we talk about other kinds of blue screen codes’ reasons and solutions.

0×0000006F:SESSION3_INITIALIZATION-FAILED

Error Analysis: this blue screen code indicates that the session manager process creation failed. This error usually happens when you boot your laptop, usually caused by the error device driver or system files.

Solution: if you installed hardware recently, you can disable and remove the hardware, and then you can see if the problem is still.
If removing the hardware doesn’t work or you don’t do any installation, you can reboot your laptop with recovery options set to create a dump file. Followed by it, you can reboot your laptop with the selection of Last Known Good option.
If the blue screen code continues to appear, I recommend you use the Windows installation CD to repair the system.

0×00000077:KERNEL_STACK_INPAGE_ERROR

Error Analysis: this blue screen code indicates that requested page of kernel data could not be read in. This error code indicates disk hardware failure, disk data corruption, or possible virus infection.

Solution: STOP: 0×00000077 (parameter, parameter, parameter, parameter), if the first and third parameter are zero, it indicates that there is a problem of your laptop hardware. If you installed hardware recently, you also need to disable or remove the hardware.
In case of the virus infection, you can scan the system with the antivirus software.
At last, you can check and repair the disk errors by running the Chkdsk follow the instructions.

0×0000007A:KERNEL_DATA_INPAGE_ERROR

Error Analysis: this blue screen code is often caused by that the kernel data in the virtual memory can not be read into memory. The reason may be that the virtual memory paging file has the problem of bad cluster, viruses, and disk controller error or memory issue.

Solution: first of all, upgrade your anti-virus software to the latest version to see if there is virus in your laptop.
If there is 0xC000009C (indicates bad blocks (sectors) on the hard disk) or 0xC000016A code (bad blocks (sectors) on the hard disk) in the blue screen code information, it is resulted from the bad clusters, and if the system disk inspection tool can not repair it automatically. In this time, you should enter the Recovery Console and running the Chkdsk command.
And when you see this blue screen code, you also can see the blue screen code of “0×00000077:KERNEL_STACK_INPAGE_ERROR”.

0×0000007B:INACESSIBLE_BOOT_DEVICE

Error Analysis: this blue screen code indicates that when Windows can not access the system partition or boot volume in the boot process. This problem usually occurs in the first boot time when you have replaced the motherboard; it is mainly because that the disk or SCSI controller with the new motherboard is different from that of the old motherboard so that the laptop can not support it. Also, this error might occur because of the installation of a new SCSI adapter or disk controller or if the disk was repartitioned with the system partition.
This blue screen code might occur because of the virus infection or damaged hard disk.

Solution: generally, you can solve this problem as long as you boot your computer with the installation CD-ROM and do a repair installation.
If that is because of the damaged hard disk itself, please install it to another computer, and runs the \\chkdsk / r \ \ command to fix the errors followed by the instruction.
For more information about hard disk corruption, you can see the “Stop 0×00000024 or NTFS_FILE_SYSTEM” in the article “Blue Screen of Death STOP Codes (two)”.
If this blue screen code is caused by the virus, you can scan the system with the antivirus software.

0×0000007F:UNEXPECTED_KERNEL_MOED_TRAP

Error Analysis: this blue screen code indicates that a trap occurred in kernel mode, the kernel is not permitted to have or intercept.
This blue screen code may also caused by the defective hardware such as memory hardware or some kind of software.
Sometimes, overclocking will also result in this error.

Solution: try to use the detection software such as Memtest86 to make sure that if the memory is overclocking, if it is the problem of the overclocking systems, restore all clock and bus speed settings to the manufacturer recommended.
In addition, if there is a problem of the overclocking systems, the South Bridge chip of the motherboard will overheat, so lower the temperature of the South Bridge will makes the laptop works well.
This blue screen code can occur by the installation of incompatible applications, drivers, or system services, you can disable or remove it, and moreover, you can also get an advice from the manufacturer.

The cost of High-resolution LCD screen is higher than the low-resolution LCD screen, but high-resolution notebook is not necessarily suitable for all types of users. If it is at the same price, you must be based on your individual application requirements as the sole judging criteria.

Here is a misunderstanding, that is confusing LCD and CRT monitors resolution, people hold the opinion that the laptop LCD screen resolution is adjustable. Such as laptop LCD screen with a resolution of 1920 × 1200, if they feel the font is too small in 1920 × 1200 display mode.Can resolve the small font problem by adjust to 1680 × 1050 or 1440 × 900? The actual situation shows that the resolution on the laptop LCD screen to make any changes will affect its display, there will be a small degree of burr light phenomenon, can also cause stretch.

How to solve the high-resolution LCD screen font smaller problem? There is another method that is to change the font in Display Properties WINDOWS option: click the right mouse button on no icon region of the desktop,then click the property,or click on control panel,then“Appearance Theme”, choose “display font size”. But in that case, it will erase the advantages of high-resolution LCD screen.

The main advantage ofthe high score screen is providing a natural field of vision and more work area, such as panoramic animation, sophisticated financial statements, cross-page file operations, the biggest advantage is that we can enable users to increase the working area, it could also show more of content, so users can simultaneously conduct a number of work without frequent switching. Encounter such trouble with this, it is better one-step selection of a LCD screen size and resolution are suitable for laptop.

Therefore, the proposals we give about laptop LCD screen resolution are:

1,For the need for greater perspective of users, as far as possible the selection of large-size notebook, but the larger resolution must be priority in the same size of the LCD screen.

2, For users who require larger fonts, select portable notebook while the size meet the requirements.But in the same resolution the smaller size of the LCD screen the more priority should be given, of course, you can also change the font size to make the font become bigger.

Touchpad is currently the most widely used notebook computer mouse, HP, Dell and other brands of notebook computers equipped with it.Touchpad which is composed of board and two buttons is capable of sensing the pressure to run track a sense of by a finger.Two buttons is equivalent to the standard left and right mouse button. Touchpad is no mechanical wear, the control accuracy is also good, the most important thing is that it is too convenient to beginnners to use.A number of notebook computers even extend handwriting input function into touchpad.However, the disadvantage is that the user’s fingers wet or dirty, it will not be so smoothly in control.

Track Point was invented by IBM, now common in Thinkpad and Toshiba notebook computers, it has a small button located on the keyboard of the G, B, H. There are two major button at the buttom of a blank button. Finger the small button to be able to sense the size and direction of thrust, and thus to control the mouse movement trajectory, while the large button is equivalent to the standard left and right mouse button.

Track Point is characterized by movement speed, positioning accuracy, but the control was a bit difficult for benginners. But many users are enthusing about trackpoint after have mastered the use of know-how. The disadvantage is that the button jacket with a long easy to wear off, then must be replaced.

About Touchpad

A touchpad is a pointing device consisting of specialized surface that can translate the motion and position of a user’s fingers to a relative position on screen. Touchpads are a common feature of laptop computers and also used as a substitute for a computer mouse
where desk space is scarce.

Touchpads are primarily used in portable laptop computers, because a standard mouse requires a flat surface near the keyboard not always available outside of a standard computing environment. Because the touchpad’s position is fixed relative to the keyboard,
and very short finger movements are required to move the cursor across the display screen, many users find touchpads preferable, and desktop keyboards with built-in touchpads are available from specialist manufacturers. However, these features can also cause frustration when a user’s thumb accidentally swipes over the touchpad while typing.

It may appear screen tearing problem when you use LCD Screen. Base on our repair experience, we summarized the following methods that can solve most of LCD screen tearing problems ( It’s best to exclude problems according the gradual process in practice).

First: Check the connection between the LCD display and graphics is loose. It is the most common phenomenon that apppear clutter waves.

Second: Check Graphic card is overclocked. If the Graphic card is overclocked to use, they often turn up irregular and discontinuous stripes. Then ,you should appropriately reduce overclocking range. First of all is to reduce the frequency memory.

Third: Check the quality of Graphic card. If Screen Tearing comes out after you have replaced Graphic card and practised the first and second step, you should check the Graphic card of anti-electromagnetic interference and the quality of electromagnetic shielding are qualified. Put some of the components that may result in electromagnetic interference away from the Graphics card when you installing (such as hard disk), then look at whether Screen Tearing is disappear. You should replace the Graphics card or doing home-made shielding if the Graphics card’s electromagnetic shielding function is ineligible.

Fourth: Check the display resolution or refresh rate set is too high. LCD resolution is generally lower than CRT monitors, if it exceeds the manufacturer’s recommended best resolution, there may present Screen Tearing phenomenon to you .

Fifth: Check whether have installed incompatible graphics card driver. Such cases are generally easily overlooked for the pace of the graphics card driver update is increasing (in particular, NVIDIA graphics card). Some users always install the latest version of the driver. In fact, some drivers are either the latest beta version, or specific for graphics card or a game-optimized version,sometimes using such drivers may lead to the emergence of Screen Tearing. Therefore, it is recommended you to use the graphics card drivers manufacturers provide.

Sixth: If you still can not solve the problem after having used five methods above, there may be the quality problems of displays. Please replace the other display.

Knowledge on Screen Tearing
Screen tearing is a phenomenon in video where a newly rendered frame overlaps a previously rendered frame, creating a torn look as edges of objects (such as a wall or a tree) fail to line up. This occurs when the video card or the software using it begins updating the actively-displayed memory in a manner that is out of sync with the monitor’s refresh rate.

Tearing can occur with most common display technologies and video cards, and is most frequently seen on systems where horizontally-moving visuals are commonly found, such as in slow camera pans in a movie, or classic side-scrolling video games. The material being shown may also exhibit vertical stretching or shrinking, or repeated parts of images, during vertical motion, depending on the nature of the video.

Why my laptop screen becomes black? It is a very common question. Now, I’d like to summarize the reasons of the black screen and how to deal with it:

First: It could just be a screen saver. In this case, wiggle the mouse or hit a key on the keyboard, your screen may come back. You can adjust the screen saver behavior in the Display portion of Control Panel.

Second: It could be your computer. The most common abnormal reason for a black screen is probably a computer crash. One simple way to determine if it’s just the monitor going out or the computer crashing is to play some audio on your computer. Perhaps load up a longish mp3 play list, for example. If the monitor goes black, but the music continues to play, you know that the computer is running, and that the problem is either the video card, video drivers, the monitor or the cables in between.

Third: It could be a virus, or your computer’s other software or drivers. Unfortunately bad drivers for any hardware on your system can cause the machine to crash or go to a black screen without warning. I’ve also heard of this as a symptom of a virus (though typically a poorly written one). It’s more common that you’ll actually get a message, or the dreaded “blue screen of death”, but nonetheless, it’s still possible that bad software, particularly hardware drivers, could cause it. As always, make sure your computer is up to date on Windows and of course anti-spyware and anti-virus software as well.

Forth: It could be your video drivers. Even though I’ve already mentioned drivers in general, the video drivers are worth a closer look. The software used to control the video card, which can often be quite complex, can also fail, have a bug, or crash in such a way that the screen goes black. Therefore, making sure you have the latest drivers always makes sense.

Next time, if your screen gets black, please have a try.
