The notebook computer hard disk noise of the causes and repair methods
I recently discovered in playing games or watching hd movies after exit, hard disk dell inspiron b130 series laptop cpu cooling fan will have "snickering" voices, why hard disk will be abnormal sound, notebook hard disk abnormal noise will not affect the life of the hard disk?. Follow the below to view the cause of abnormal sound hard disk and the method of resolution.
The reason is in the system of free time, hard disk head will be home, for some hard disk speaking, head home will bring about such cryptids, on the surface will not affect the normal use, but should pay attention to, once head home to 100000 times, read disk will appear delay, pause and reaction, and head home 600000 times, hard disk basically one foot in the grave. Therefore,dell inspiron e1501 series laptop cpu cooling fan whether out of to reduce noise pollution consideration, or out of hard disk maintenance consideration, should reduce the number of hard disk head position, in the system spare time don't let hard disk head home, we can through the setting DiskInfo software to realize.
Hard disk abnormal sound solution
1, operation DiskInfo software, the software will automatically detect hard disk all kinds of information, and in the task bar icon display hard disk usage rate.
2, double-click the taskbar software dell inspiron e1505 series laptop cpu cooling fan icon, and then will pop up software main interface, in the "function" under the menu select "advanced features".
3, and then select "AAM/APM control", and click "AAM" project "enable" button, will slide block move to "quiet mode" position, which can reduce the hard disk power consumption and the work noise.
4, click "APM" project "enable" button, will slide block move to "performance mode" position, so only in shutdown in hard disk head will be home.
Because work head not home, so hard disk earthquake resistance will be reduced, so hard disk of abnormal sound can solve, use this way, laptop computers dell inspiron m140 laptop cpu cooling fan don't violent vibration, the proposal on solid using a notebook on the table when using this way.

Graphics common troubleshooting
Common fault one: show no boot
Such fault general because graphics and motherboard bad contact or motherboard toshiba satellite a10 sp129 laptop cpu cooling fan slot have caused problems. For some integrated graphics motherboard, if memory Shared main memory, it is required to pay attention to the position of the memory bank, generally in the first memory bank slot should be inserted in a memory bank. Due to the graphics cause boot show no fault, after startup generally will be issued a long two short bumming (for AWARD BIOS for video card).
Common fault 2: display flowers screen, see not clear handwriting
This kind of failure is usually due to a display or video card does not support high resolution and cause of. Flowers screen can switch startup mode to the safe mode, and then in the Windows 98 to enter the display Settings, 16 color state click on the "application", "ok" button. Restart, Windows 98 system normal mode delete graphics driver program, and then restart the computer toshiba satellite a15 s127 laptop cpu cooling fan. Also don't enter the safe mode, in pure DOS (henan emba) environment, editing SYSTEM. The INI file, will display. DRV = pnpdrver to display. DRV = VGA. DRV, save exit, and then in the Windows update driver.
Common fault 3: color display is not normal, this kind of failure usually have the following reasons:
1. The graphics card and display signal wire bad contact
2. Display their own fault
3. In some software running in the color is not normal, general common in old machine, in the BIOS has a school
Check the color options, its open can
4. Graphics damage;
5. Display was magnetization, this kind of phenomenon is toshiba satellite a15 s129 laptop cpu cooling fan generally with magnetic objects can too close to be caused by, magnetic change after may cause show scenes appear deflection phenomenon.
Common fault 4: system halted
Such fault appears more commonly found in main board and the graphics card not compatible or motherboard and graphics bad contact; graphics
And other expansion card not compatible can also cause system halted.
Common fault five: screen abnormal noise point or design
This kind of failure is usually due to the graphics memory problems or graphics and motherboard bad contact cause. Need to clear clean graphics goldfinger site or replace graphics.
Common fault 6: graphics driver program lost
Video card driver loaded, running after a period of time the toshiba satellite a15 s1292 laptop cpu cooling fan drivers are automatically lost, this kind of fault is generally in graphics by poor quality or graphics and motherboard not compatible, make graphics temperature is too high, resulting in system operation instability or appear crash, the only change video card.
In addition, there is a kind of special circumstances, before can be loaded with graphics driver program, but in graphics driver program load into, into the Windows there was a crash. Replaceable other types of graphics in load the driver, insert the old graphics resolved. If it can't solve the fault, then explaining the registry fault, to the registry in henan from toshiba satellite a15 s157 laptop cpu cooling fan an line recovery or reinstall the operating system can.

The mouse only quantitative index is the samsung np n145 jpm3 laptop keyboard interpretation of the degrees,
explain degree also called resolution, and image correlation is an
important concept, it is a measure of the technical parameters of image
detail expressive force. But the explanation degree type has a lot of,
its meaning is different. Explain degree with each inch can be produced
on the points that DPI (DotsPerInch) to measure. To explain degrees from
three aspects to determine: optical parts, hardware and software part.
But the mouse explanation degree and no special software to measure,
light see manufacturers released by the numerical are not reliable. So
this time we design a new scheme to test the performance of the mouse. A
brief introduction of steps:
1, on a piece of white paper on 2 cm draw a straight line, don't think 2 cm distance is very short, this 2 cm with the mouse reaction on the screen distance is almost 20 cm! (for ease of measurement, the display USES a 800 x600x16bit resolution.
2, open Photoshop, create a new blank documents, size for 500 x1200 pixel.
3, choose 9 pixel brush to draw down the samsung np n150 ja05 laptop keyboard mouse movement trace (with a square box pressure online on boundary, in case the mouse go wide), then carefully and uniform to school official cites use the mouse to carry off over the line.
4, finally use Photoshop scale measure off the mouse pointer on the screen moving distance.
5, this distance reflect the mouse explanation degrees, the mouse to explain the degree, the corresponding pointer on screen moving distance is bigger also.
What say here can be observed the change of the screen, can be cursor movement one (or N) pixels, also can be in FPS game turned to 10 degrees. This change can be made by the mouse drive or software (game) Settings to change, but one of the most basic, the most subtle change can only be cursor movement 1 pixel. We discussed here is 1 pixel change. But the mouse must move minimum distance, is the reciprocal DPI. If the mouse is 200 dpi,samsung np n150 ja07 laptop keyboard then the mouse A must move 1/200 inch, screen cursor movement 1 pixel. And the other one each 800 dpi mouse B, simply moving 1/800 inch, the cursor can move 1 pixel.
This is the first layer in the sense of precision difference, is the mouse to tiny moving response ability. When the mouse B moved 1/200 inch, screen cursor can move four pixels. The samsung np n150 jp06 laptop keyboard show as A result of which the mouse B cursor movement speed is faster than the mouse A 4 times (by this time the mouse itself movement speed is the same). So in the same mouse movement distance, DPI value low mouse A can obtain higher cursor movement speed? (note, is the cursor speed)?
Of course no problem, drive to an accelerated went. A not mobile 1 pixel, but four pixels, then it can and mouse B the cursor movement speed. But the new problem and produced, mouse 1 itself fast moving may also can't see, when the mouse moves slowly, you will find the mouse on the screen cursor always only in a multiple of 4 number of pixel stay, the mouse cursor beating the mobile. This is the samsung np n150 jp0b laptop keyboard second in the sense of precision difference, is the mouse to the screen pixels control ability. So high DPI mouse, can be made by small operation get high response, and at the same time maintain a high level of pixels control ability.
1, on a piece of white paper on 2 cm draw a straight line, don't think 2 cm distance is very short, this 2 cm with the mouse reaction on the screen distance is almost 20 cm! (for ease of measurement, the display USES a 800 x600x16bit resolution.

Teach you four recruit easily get Windows system optimization
System with long, each part will have redundancy, ibm lenovo thinkpad x200s series laptop cpu cooling fan bloated local influence system speed. In order to make the system run more fluent, we will often through the manual Settings or tool the system optimization. For beginners, manual setting place too much, the process is relatively complex, and system optimization is a often of work to do, so suggest or use special optimization software to optimize is more convenient. Many friends are familiar with "super rabbit" this kind of optimization tools, its function is strong, but it's still not enough ShaGuaHua, this period we introduce a small tool XPy, just simple steps, can let the system to optimize.
A, what you need to do optimization
System after download and install where need optimization? First the rookie to Chou Chou, so in XPy in setting optimization options will have targeted the.
1. The page file system optimization
2. System start menu popup speed too slow, icon cache is ibm lenovo thinkpad x300 series laptop cpu cooling fan too small, need to adjust.
3. The default launched some independent service, has nothing to do with port may be safe hidden trouble.
4. Some application after installation will self-assertion in the start menu since the launch of the program to add the corresponding items (such as installation Office after some input method entries appear in the automatic item).
5. System can not be automatically according ibm lenovo thinkpad x301 series laptop cpu cooling fan to your network link mode set different maximum transmission unit equivalent; IE and connection number is too small.
6. The system default installation Microsoft offer of some software, don't need can be removed completely.
7. Software uninstall not completely, the system still have residual files or registry key.
Second, the quick setup XPy
First start XPy, in the "Settings" (set) ibm lenovo thinkpad x61 7673 laptop cpu cooling fan window choose the type of optimization, simply from the drop-down list can choose scheme. XPy besides contains "No Settings" (don't change system original Settings) outside, optimization Settings combination also contains the following modes, and every kind of mode have good match for you the related items:
"XP Antispy Settings" : anti-spyware program setting. Which can improve the ability to prevent malicious software (for Windows XP effective).
"All possible setting (Auto Detection)" : automatically detects All possible needs to adjust the project, the proposal USES.
"All Settings" : All optimization, automatically in XPy will provide optimization option All selected and applied into the system.
"Custom" : completely by the user choose our need to set up entries, but there are some difficulty for beginners.
O sprout tip: generally don't choose ibm lenovo thinkpad x61 7674 laptop cpu cooling fan"No Settings" and "All Settings," the former not optimization, while the latter may optimize excessive lead to new problems. Try to choose customizable set.
According to the different choice models still need to affirm, then click "Apply" button, in the next "Installing" dialog box, the software will be the home on the system provide necessary modifications, click the "Show Details" button to view Details. Then ask if restart to complete the final modification, restart your system will be selected according to the model optimization.
Three, system Settings, give me the right to know
XPy can also let users have to set up the system of right to know - when the mode choice, in the list, you can detailed view each mode changed exactly what project.
For example, choose "XP Antispy Settings" item,ibm lenovo thinkpad x61 7675 laptop cpu cooling fan you will find it only chooses the "General" (conventional), "Services" (Services), "Internet Explorer" (IE browser), "Windows Media Player" (Media Player), "Windows Messenger" this several, it only for these entries of small projects to carry on the revision, and spread the corresponding items, you can better understand XPy exactly what to change.
For example, in "XP Antispy Settings" (anti-spyware software pattern) expansion "Internet Explorer", we find it only in the following Settings: "Disable Automatic Updates" (prohibit Automatic Updates), Rename UPLDDRVINFO HTM. "(will UPLDDRVINFO. HTM file renaming), UPLDDRVINFO. HTM file is" Windows XP HCP URI can be directly deleting files loopholes "may be used in a document, because the browser submitted HCP URI request existing safety problems, therefore has the hackers will use the file of the ActiveX control to delete local files, this belongs to the dangerous file,ibm lenovo thinkpad x61 7676 laptop cpu cooling fan affected system including Windows XP home edition and professional edition, many security experts have suggested directly deleted, and XPy approach is to name it. If you want to under this model are fixed more depth system Settings, completely available checked.
O sprout tip: through this detailed Settings, you can completely will system optimization Settings control on palm, understand exactly what the project is modified. The comparable one by one into the system registry or service manager and other Settings much more convenient to use.
Four, give you an undo key, sorry, don't worry optimization excessive
If you graph save trouble and dark chose "All Settings", ibm lenovo thinkpad x61 7677 laptop cpu cooling fan in the discovery after restart the system operation anomaly also need not nervous, and many system set up different is, XPy provides "regret medicine", you can easily modify the previous reduction set to (a lot of software just optimization, does not give you the optimization of the right to know, let alone make you Restore previous set up), particular way is rerun XPy, in tip picture click the "Restore" button, and then click "Apply" button can return to its original state.
This mechanism, you don't have to worry about system is "optimization excessive", once the system has any exception, you can quickly restore previous state.ibm lenovo thinkpad x61 7678 laptop cpu cooling fan When you play in new system after the patch, use the system to do some XPy set-up, no doubt will be quite convenient, and the optimization effect is also very obvious.

And the other one each 800 dpi mouse B, simply moving 1/800 inch, the cursor can move 1 pixel.
This is the first layer in the sense of precision difference, is the mouse to tiny moving response ability. When the mouse B moved 1/200 inch, screen cursor can move four pixels. The show as A result of which the mouse B cursor movement speed is faster than the mouse A 4 times (by this time the mouse itself movement speed is the same). So in the samsung n128 laptop keyboard same mouse movement distance, DPI value low mouse A can obtain higher cursor movement speed? (note, is the cursor speed)?
Of course no problem, drive to an accelerated went. A not mobile 1 pixel, but four pixels, then it can and mouse B the cursor movement speed. But the new problem and produced, mouse 1 itself fast moving may also can't see, when the mouse moves slowly, you will find the mouse on the screen cursor always only in a multiple of 4 number of pixel stay, the mouse cursor beating the mobile. This is the second in the sense of precision difference,samsung n140 laptop keyboard is the mouse to the screen pixels control ability. So high DPI mouse, can be made by small operation get high response, and at the same time maintain a high level of pixels control ability.

1, on a piece of white paper on 2 cm draw a straight line, don't think 2 cm distance is very short, this 2 cm with the mouse reaction on the screen distance is ibm lenovo thinkpad x201 laptop keyboard almost 20 cm! (for ease of measurement, the display USES a 800 x600x16bit resolution.
2, open Photoshop, create a new blank documents, size for 500 x1200 pixel.
3, choose 9 pixel brush to draw down the mouse movement trace (with a square box pressure online on boundary, in case the mouse go wide), then carefully and uniform to school official cites use the mouse to carry off over the line.
4, finally use Photoshop scale measure off the mouse pointer on the screen moving distance.
5, this distance reflect the mouse explanation degrees, the ibm thinkpad t41p 2669 laptop keyboard mouse to explain the degree, the corresponding pointer on screen moving distance is bigger also.
What say here can be observed the change of the screen, can be cursor movement one (or N) pixels, also can be in FPS game turned to 10 degrees. This change can be made by the mouse drive or software (game) Settings to change, but one of the most basic, the most subtle change can only be cursor movement 1 pixel. We discussed here is 1 pixel change. But the mouse must move minimum distance, is the reciprocal DPI. If the mouse is 200 dpi, then the ibm thinkpad t60 laptop keyboard mouse A must move 1/200 inch, screen cursor movement 1 pixel.

Every time the computer normal shutdown time bluescreen crash is what?
"Bluescreen" phenomenon more and memory size, CPU frequency, cd-rom, hard disk fragments and so on close... In the use of computers in the process, often meet the situation of physical memory physical memory dump complete. For acer aspire 5810t laptop keyboard beginners speaking, like is a computer disaster, at a loss. In fact as long as the understanding of the reason and need not be afraid of. Cause the cause of physical memory physical memory dump complete computer has a lot of kinds, hardware reasons overall can be summarized as the following kinds:
A, screen display system is busy, please press any key to continue...
1, virtual memory inadequate system multitasking operation error
Virtual memory is a WINDOWS system a kind of special solve system resources method, the general requirements of the master boot disk surplus space is the physical memory 2-3 times. Some enthusiasts in order to make full use of space, will own hard disk plug to full, busy record WINDOWS the stringent requirements. As a result of the virtual memory because of lack of disk space and appear operation error,acer aspire 6530g laptop keyboard so they appear bluescreen. To solve this problem is very simple, try not to the hard disk engorged, often should delete some system to produce a temporary files, swap file, which can release space. Or can manual configuration virtual memory, select the advanced, the virtual memory the default address, turn to other logical dish. This will avoid the virtual memory because of insufficient and cause bluescreen.
2, CPU overclocking lead to operation error
It is common for enthusiasts overclocking, so from o.c. caused by all kinds of fault is the unavoidable. Overclocking, itself is in the original foundation finish higher performance, but as a result of the overload operation, cause its internal operation too much, make the CPU overheating, thus cause the system operation error. Some CPU overclocking performance is better, such as INTEL's celeron and AMD - K6-2 processor are relatively good, but sometimes also can appear some puzzling mistakes. (for acer aspire 7110 laptop keyboard example: I have tried to INTEL cy young 300 a, in overclocking to 450, floppy drive without take orders, to read disk operation). INTEL's less than 200 CPU as well as AMD - K5 overclocking ability is not so good. Suggest high-grade CPU to overclocking, then heat dissipation work will be done, had better hold a big fan, plus some silica gel and so on cooling material. As for some low CPU I suggest you had better not overclocking, lest overclocking can not reach the desired effect but often appear bluescreen influence computer normal speed.
Second, the memory bank of no compatible or damage caused by operation error
At this moment the most intuitive phenomenon, because of this phenomenon are often in a boot time can see, simply can't start the computer, pictures revealed in memory has a problem, ask you whether you want to continue. This kind of mistake is caused by the damage of the physical memory or memory and other hardware caused by acer aspire as4720-4721 laptop keyboard incompatibility. At that time only to change another a memory.
Three, cd-rom reading the disk is abnormal open will move mountains
This phenomenon is in the cd-rom is read data, due to be misoperation open and causing bluescreen. This problem does not affect the system normal action, as long as to bounces CD or press the ESC key can.
The above is my in the maintenance of the computer to run into several kinds of physical memory physical memory dump complete reason, maybe there will be some other puzzling problems lead to computer appear bluescreen. Anyway, meet this kind of problem, should be carefully analysis the reason of this problem, and then set out to solve.
Four, hardware the remaining space is too small or too much debris
Win9X due to run hard disk for acer aspire as5315-2142 laptop keyboard virtual memory, this requires hard disk must keep certain free space to ensure the normal operation of the program. Generally speaking, the minimum shall ensure that more than 100 MB of space, or appear "bluescreen" is likely to drive the remaining space is too small relevant. In addition, hard disk fragments too much, also easy to cause "bluescreen" appear. Therefore, every once in a while a fragment consolidation is necessary.
Five, the system hardware conflict
This kind of phenomenon cause "bluescreen" is more common. Practice is often met in sound card or graphics card setting conflict. In the "control panel" - > "system", "equipment management" check whether there is a question mark or an exclamation mark with yellow equipment, such as existence can try to delete them, and acer aspire as5315-2191 laptop keyboard restart the computer, by Win9X automatic adjustment, general can solve the problem. If not yet, can be manually adjusted or upgrade the corresponding driver.
"Bluescreen" software causes and solutions
And hardware close contact is software, sometimes software in "bluescreen" phenomenon also "contribution", loading too much procedures, the registry has a problem, soft hard not compatible, the driver has a problem, relative to the hardware reasons to not easily perceive some, but to pay attention
A, boot loader too much
Don't start loading too many applications acer aspire as5315-2940 laptop keyboard (especially your memory is less than 64 MB), lest make system resources consumed. Under normal circumstances, Win9X start after the system resources should be not less than 90%. Had better maintain at 90% above, if after the start not run any program is lower than 70%, will need to shed part of the application, or may appear "bluescreen".
Second, the application exists BUG
Some application programming the defects in or error, run when it conflicts with Win9X or scramble for resources, cause for its Win9X cannot allocate memory address or meet its protective error. This BUG may be unpredictable, free software is most common. In addition, due to some users in using pirated software (including piracy Win9X), these pirated software in the decryption process will damage and the loss of part of the source code, so that the software is very unstable and unreliable, and often cause "bluescreen".
Three, was unknown programs or virus attack will move mountains
This phenomenon as long as it is at ordinary times we are online and encounter, when we in the surf of the time, especially into some BBS station, may expose their IP, is a "hackers" use some software attack will move mountains. This is the best for each other in their computer installation some defense software. Another is the login BBS to security Settings, hide their IP.
Four, version conflict
Some applications need to call a particular acer One A110 laptop keyboard version of the dynamic link library DLL, if in the installation of the software, the old version of the DLL covered the new version of the DLL, or delete the application, the mistaken delete the useful DLL file, it is possible to make the above call failure, so as to appear "bluescreen". Reinstall the might as well try.
Five, the registry errors or damage
In many cases this is appear "bluescreen" main reason. The registry kept Win9X hardware configuration, the application Settings and user material and other important data, if the registry errors or is damaged, it is very possible to dell 0nc929 laptop keyboard appear "bluescreen". If your computer often appear "bluescreen", first of all you should consider is the registry problems, should be timely to the test, repair, to avoid more loss.
Six, software and hardware not compatible
The new technology, new hardware development soon, if installed the new hardware is often "bluescreen", the most and motherboard BIOS or driver too old related, so that cannot very good support hardware. If your motherboard BIOS dell 0nk750 laptop keyboard upgrade support, should as soon as possible to upgrade to the latest version or install the latest device driver.

Software causes of computer system halted
In the use of software, will often appear the hp 540 laptop keyboard phenomenon of crash, although can through the task manager in exit process, but also want to analysis of what is the main reason?
1. The virus infection
The virus can make computer efficiency fell sharply, causing frequent system halted. Need 360 security guards, rising, kappa and other antivirus hp 550 laptop keyboard software to carry out comprehensive herbs, antivirus, and do timing upgrade anti-virus software.
2. Software installation, configuration problem caused by the crash
If the software installation process system halted, may be some system configuration and installation of the software have conflict. If the hp 6530S laptop keyboard software installed crash, it is mounted program and system conflict, but through the delete new installation program to solve the system halted problem.
3. Loading program too much or too little system resource, which make the system resources consumed, make the individual program need data in memory or hp 6535S laptop keyboard virtual memory can't find, also can appear abnormal error.
4. Hard disk the remaining space too little or too much debris, if the rest of the hard disk space is too little, because some application hp 6730S laptop keyboard operation needs a lot of memory, so need to virtual memory, and virtual memory is provided by the hard drive, so hard to have enough the remaining space
