Three Ways to solve computer noise
|
Laptop noise, almost because of these aspects: power supply fan, CPU fan, case fan, graphics card fan noise; hard drives and optical rotation of the noise; resonant voice.When we hear the laptop running the "buzzing" sound, that is, the superposition of these voices, to reduce computer noise, a separate power supply or use of a quiet CPU fan is silent, often can not achieve good results, you need to From the start of each source of noise problems. 1, The fan noise elimination HP Pavilion DV9000 CPU fan noise is the main source of noise. Power supply fan noise problem easier to solve, direct purchase of a quiet power to it. power supply fan noise is generally lower, while the CPU fan speed is low,less affect the CPU's heat, so the main CPU or a noise reduction method is the bearing lubrication and the structural design of blades. As high-speed CPU fan, CPU fan making the noise value to achieve the level of power ,a little bit quiet difficult, but we try to choose a fan with a mute function. Of course, add yourself to the point of the fan bearing lubricant is also a good way. Graphics card fan and chassis fan noise is relatively smaller, but too many installed in the chassis chassis fan, will increase the HP DV9000 noise. As little as possible to install the fan is an effective means of noise reduction, but for those who need to install multiple chassis fan computer, you can choose a number of large-diameter low-speed case fans. 2, The hard disk or optical drive noise reduction As technology improved hard disk, hard disk read and write data annoying "giggle" sound is basically not hear, but some of the hard disk rotation is the "buzz" sound is relatively significant. Currently, Sony VGP-BPS13 hard disk manufacturers have launched some of the concept of quiet hard drives, such as the use of "Fluid Dynamic Bearing" technology, Seagate and Samsung V Series hard drives are a good choice. CD-ROM often difficult to solve the noise problem, some drive noise even reached alarming proportions, with some friends, saying, read the disc when "the same as the helicopter." Some friends installed as DVD-ROM Utilities software, the use of CD-ROM, mainly when watching DVD, effectively reducing the optical noise. 3, The elimination of resonance noise Not every computer, include HP Probook 4710S, will have a resonance noise, eliminating noise resonance method is very simple to adjust the placement of the chassis or increase the number of pillows on it.Increase the sound-absorbing cotton inside the chassis is not a good way, so that the heat tends to affect the case. These are just a commonly used method, in fact we hyperactivity little clever, and the noise problem is not really the "problem" was. |

Failure caused by notebook computer batteries
|
I often repair the computer to others, recently encountered three cases of notebook Dell M1210 does not boot, shutdown problems, which are battery related. Resolution process will now be written, so that the growing number of notebook computer users can get some inspiration. Example One: Asus 1005 notebook Celeron CPU, the failure phenomenon is when you boot into Win 98, can not find the system file prompt appears, it can not enter Safe Mode. Check and clear the virus, boot, failure remains. Re-install the system, there SUXXX error and can not continue with the installation, then to delete the system re-installation. Just then, the system can not boot the. Carefully check the power supply light is not lit, and the laptop all the lights are not bright. Check the external power supply, it did not find any problems, remove the external power supply, nor can the computer lights. I do not know how to do, suspected of computer hardware problems. Suddenly, inspiration, take down the laptop's battery, then the external power supply connected, the indicator light notebook computer, the machine normally. Example two: Toshiba laptop suddenly can not boot one day, but after relieved the battery ,computer working. Example Three: Another unknown laptop,maybe Apple A1189 CPU is P a level. Friends at 2 am wake up from my sleep, said her laptop computer crashed, no reset button, can not be shut down. I told her laptop and its external power supply disconnect the battery removed. But how she can not remove the battery. Later, the others help, she unloaded the battery. After it is installed and then go back to solve the problem. The number of cases above show that the Apple A1189 Battery is very easily lead to not boot failure. When your laptop will not boot, all the lights are not bright, you can try to remove its battery to see if an external power supply to power through. Try it, most can solve the problem. |
Four analysis and countermeasure for laptop restart and crash
|
Restart the computer, including Acer Aspire 4810T notebook computers and crash failures, computer repair process is a hot issue, which is involved in all aspects of the problem, not a few words can all be summed up. Here I only initiate in conjunction with their usual maintenance experience, do some simple analysis of these failures, if improper, but please correct me. The following analysis focused on 600 and T series. Laptop restart, crash failures including a few aspects: First, hardware failure 1 ,restart caused by power problems, crash failures, such as voltage instability, surge, underload and so on. Laptops Acer Aspire Timeline 3810 are delicate, fragile look at the power adapter and notebook computer power supply circuit board can know. Measures: a, attach the battery, not through fear of mischief and to reduce the weight of the battery remove the battery, especially in areas where power is not so stable. After all, the battery is quite intelligent, and unless some of the mentally retarded product, otherwise there will not be any major problems. Also to note, do not expose the battery to low-temperature environment, it will affect the battery's activity. This can be verified to the battery manufacturing plant, where there are save laptop batteries with air temperature of 40 degrees. So do not be afraid of our battery is "hot" with the. 2, not the Acer Aspire Timeline 4810 Battery and high-power electrical power strip connected to the same seat, in particular the high-power electric air-conditioning and so on. For this reason we all know, I do not say. Members of the power adapter I had for this reason was shot through. Second, the software failure 1, the virus, which goes without saying. Solution is to buy genuine anti-virus software, the key is to constantly upgrade, the Internet, the best is to upgrade anti-virus software. Never upgrade or update antivirus software and little deaf ears is no different. 2, directx restart and crashes caused by failures. Countermeasures: A, re-install or update the driver B, cancel directx device for testing. 4, the conflict between the software measures: A, try to avoid the use of test software, B, remove the software causing the problem easily, C, installation of system optimization software, such as optimization of the Acer One master and so on. |

HP Pavilion DV7 can not shut down automatically
|
HP Pavilion DV7 Can not automatically shut down, there are several reasons: 1, may be incorrect BIOS settings, boot or restart the computer hold down the DEL key to enter the BIOS. Find Load Fail-Safe Defaults, press the arrow keys to select after the carriage return, prompted to confirm, press Y, Enter. Finally, select the Save & exit step (saving settings), press the F10 can also directly. Press Y hit enter. Take the initiative to restart ! Enter the BIOS settings menu ,set the "keyboard power On" of "POWER" to "Disabled" ,Press F10 to save the configuration information, restart the computer. 2, Enable Advanced Power Management solution can solve HP DV7 not take the initiative to shut down, open the Control Panel / Power Options / Advanced Power Management / Check the "Enable Advanced Power Management Support" determined by application. 3, open Control Panel / sex with Maintenance / Power Options / Advanced / In the power button options "when you press the power button on the computer" drop-down list, select the "off" to the application and determined. 4, virus infection, with anti-virus software and malicious software conducted in safe mode killing viruses and malicious software. 5, USB devices conflict, pull off before the USB device. 6, Pavilion DV7 software is not compatible, and some anti-virus software is conflict with the system, before turn off, first to shut off anti-virus software, monitoring functions can be turned off. If the failure occurred before the downloaded application software, come out the failure, please uninstall it, if troubleshooting, and then re-download and install, if not, do not apply. 7, check the motherboard, motherboard aging, capacitor failure or explosion pulp, which can cause failure that can not take the initiative to shut down and change damage capacitor will be ok. Then clean up the dust inside the laptop, plug about graphics cards, memory, polished graphics. 8, can not take the initiative to shut down, that is, crash when shutdown ,can be CPU fan with too much lead dust, the proposed clean up CPU fan and heat sink of dust, the new thermal grease added, if a fan is another question ,replace it. 9, Caused by inadequate power ,to test like that, if the computer has a CD-ROM drive, floppy drive, or recorder and other hardware, you disconnect their power supply, which can reduce power consumption to see if you can start properly. 10. DV7 Power shortage can also cause trouble, recommendations, and replace higher-power power supply. |
How to determine failure of variety of hard drive?
|
Given the different brands of hard disk have different failures, so to separate it, but whatever, the reason that the hard drive do not turn is almost certainly a circuit board problem, and rarely the motor bad. MAXTOR Disk 1, Asus 1005 Disk Stop immediately after turn on , the problem is not circuit board, is the FW error , rewritten will be ok. 2, The performance parameters of confusion, in the SYSTEM CONFIGURATIONS Department is shown as NONE, ibid. 3, POST to stay for a long time at detected hard disk , but can correctly identify the drive ID, can be displayed in the SYSTEM CONFIGURATIONS at the correct capacity, 0 bad. 4, Long time can’t get into the hard disk after the Dell XPS M1210 system boot,has bad sectors (system problem is not on the table.) 5, CMOS can be correctly identified, but show 'PRI DETECT FAIL' after self-test, failed with 1. 6, POST to stay for a long time at detected hard disk, and does not recognize the hard disk ID, felt head movements, head bad or FW wrong. 7, abnormal sound after boot, you can hear a click sound, head or circuit board failure. 8, self-MODEL is garbled, and capacity does not match in the SYSTEM CONFIGURATIONS ,the circuit board failure (cable problems not on the table.) 9, LE appears recognize disk circularly, is also FW error and be rewritten. (Continued) FUJITSU plate 1 .FUJITSU Siemens Amilo Pi 3560 Disc recognition normal, but the self-test MODEL is garbled, and the SYSTEM CONFIGURATIONS displayed NONE, FW error and rewritten will be ok. 2, disc recognition normally, self-MODEL correctly, SYSTEM CONFIGURATIONS display capacity is also correct, but can not operat under the DOS disk, such as FDISK, DM, LFORMAT etc.; FW error can be corrected. 3, POST to stay for a long time at the hard disk, but can correctly identify the drive ID, can be displayed in the SYSTEM CONFIGURATIONS at the correct capacity, 0 bad, specified : this failure can easily lead to failure 1, repair as soon as possible. 4,Even long time it can’t boot into the hard disk ,has bad sectors of non-0. 5, hard disk boot knocking, circuit board or the head or the FW issue, this failure repair rate is relatively low. 6, recognition timely, the circuit board and FW issues. 7, showing the course of knocking, circuit board or FW problem. IBM disk 1, IBM ThinkPad X200 showing boot self-test squeak, there are two possibilities, the first bad area is 0; second circuit boards and hard body bad contact, the so-called shift circuit board problem. 2, hard disk stay for a long time at boot testing, and did not detect the hard disk, but the hard drive head movement after power on, LODER problems, some need to rewrite the FW. 3, Boot self-test not detected, no sound of head movements, but rotation, head problems. 4, motor rotating bad after power on , circuit board or motor problems. 5, head back and forth sweeping move after power on, circuit board or motor problems. 6, the process of using squeaky, hard disk has bad sectors. 7, IBM X200 hard disk have squeak sound, is the head problem. |

How to solve the issue that laptop can not load official driver
|
Some brands of laptop may be to consider the compatibility, stability issues, limited only to install their own official driver; But sometimes, the official driver published too slowly, there is less easy and stablity to use than others,and this time wanna install other drivers, how to do when the installation can’t install? Dell Inspiron 1545 laptop can not load the hardware's official driver, only add their own drive manufacturers, the main reason is in line with Microsoft's genuine activity, notebook manufacturers have modified the device without permission PID values, of course, there are measures under the policy. Example: My notebook are 1b1g16mi's, 2400XT graphics card, play the game very good, but the graphics settings actually only the basic settings. Not only that, also, downloaded nearly 20 2000 series of drives but can’t installed on, it’s said that can not find the device. Is it only Dell Inspiron Mini 10 with 2300 official drivers? Was performance super garbage? Immediately went to the reasons: Acer 2400 actually changed the equipment privately PID, the Device Manager - Display Card - Properties - Details - Device Sample ID 2400XT where he actually changed the value, causing the other driver can not installed. So seek a relatively new 7-11_xp32_dd_ccc_wdm_enu_54435.exe (there should be later), extracting in Dell XPS M1210 C driver, cancel the installation. under the C drive to search *. inf file in ATI files. Many will come out this time ,to open the CX_54435.inf (such as driving is not the same model name is not the same, give you a reference path, similar to the should be is: C: ATI SUPPORT 7-11_xp32_dd_ccc_wdm_enu_54435 Driver Driver XP_INF 2400XT will be found to find the PID 2400, you were definitely not the same as under the Ha ~, and then modify: Added: "ATI Radeon HD 2400 XT" = ati2mtag_RV610, PCI VEN_1002 & DEV_94C8; "ATI Radeon HD 2400 XT" = ati2mtag_RV630, PCI VEN_1002 & DEV_94C8 Save, and then find the Dell XPS M1330 driver with the equipment, install, restart. Then open the ATI files, the files go Catalyst Registration and under the CCC to install inside the setup.exe. Recommended restart, then you can open the ATI to the 2000 System of the Advanced Settings window, the game can not be stretched. |
Troubleshooting:new Acer for installing XP drivers
|
Can you install all drivers into the new Acer Aspire One system? Especially the problems encountered the sound card drivers,. Well ,before that, you must install some more important patches program. 1.UAA HD Audio driver patching program - KB888111 This is the (UAA) High Definition Audio (High Definition Audio) class driver patch that Microsoft Universal Audio Architecture released, there are two versions: the early KB835221.exe and upgrades (the second version 1.0a) of the KB888111. Currently, more and more new Acer One laptop audio systems use UAA (The Universal Audio Architecture Universal Audio Architecture) architecture, Before Install audio device on the bus (such as sound cards, modems) I,first should installed UAA driver and then do next. 2. Dual-core processor power management features patch - KB896256 It is equipped with multiple Microsoft support processor power management features (such as Advanced Configuration and Power Interface (ACPI) processor performance state) of the processor (in a notebook is a mobile dual-core processor) computers may experience decreased performance or abnormal behavior provided by the patch - KB896256. If your Acer ZG5 laptop is a dual-core processor should be installed above the patch, or may appear slower than in the case of monocytes. This patch will be integrated into the next generation of Windows XP Service Pack 3, the system should be installed after Windows XP SP2 installed. 3. Standby or hibernation operation stops responding patch - KB909667 (Which solves the problem that can not shutdown the machine after install the camera driver, suggestions, the majority of the Friends of the installation.) Universal Serial Bus in the computer (USB) connector of the camera (many of VAIO notebook camera are built in the display above, but it is also connected to the USB Hub), camera equipment, the system operation during standby or hibernation will stop responding. Patch to solve this problem is KB909667. This patching program will also be integrated into the next generation of Windows XP Service Pack 3, it should be installed before installing Windows XP SP2 system related equipment (camera, digital camera) driver . This problem may be not install patch (in fact, is to upgrade a system file Stream.sys), and manually turn off the Power((Acer Aspire One ZG5 Battery) Management function of USB Root Hub which connected it. |

Six abnormal memory failure Elimination
|
When you start the computer and operating system or application, operation often failed due to memory exception. I use the computer for many years, summed up the reasons for memory abnormal and gives the following treatment, and I hope to give you some reference. Fault A: Apple A1189 memory slot is poor contact with motherboard, the memory controller fails as follows: When system turned on, the screen shows "Error: Unable to ControlA20 Line"and crash.after error message Solution: carefully check whether the memory slot good contact with maintain or replace the memory. Failure B: self-test passed. In DOS mode , because of the memory address conflicts when run the application, resulting in memory allocation error, the screen appears "Memory A11ocationError" prompt. Solution: Because Dell XPS M1210 Confis.sys file have not use Himem.sys, Emm386.exe memory management file for setting memory or set incorrectly, making the system can only use 640KB base memory, running larger programs will appear "Out of Memory "(memory) prompt, can not operate. These phenomena are soft fault, after redact system configuration files Config.sys, restart the system will be ok. Fault c: Windows applications running on the system of illegal access memory, too many applications in presence of memory, too many active window, unreasonable application configuration file and other reasons related can result in a number of error message about memory . Solution: Such failure must clear the memory-resident programs ,to reduce the active window, adjust the configuration file (INI), reinstall the system and applications and other ways to deal with. Four failures: Asus Eee PC 1005 Windows systems running applications under DOS (such as game software running under DOS, etc.), because the software allocated between them,the conflict occupation memory and appear black screen, crash phenomenon. Solution: Exit Windows systems, enter the DOS state, and then run the application. Failure E: That such as Dell Studio 1555 program IN virus, the virus-memory, CMOS parameter values in the size of the memory modified by virus and so on will cause the memory value does not match the actual memory size, memory, and work exceptions. The solution: use antivirus software to eliminate the virus; CMOS parameters modified by the virus, the first short circuit CMOS for discharge, restart the machine and enter CMOS , careful examination the hardware parameters , set on the memory parameters correctly. Failure F: FUJITSU SQU-809-F01 memory upgrades for expansion, memory have chosen not compatible with the motherboard. Solution: First, upgrade the motherboard BIOS, see if we can solve the problem, if to no avail, have to replace the memory. |
Tips for Acer Aspire One Memory alarm fault
|
Fault phenomena: recently,mien Acer Aspire One often need to wait regular intervals times after ac is on. Once boot into Windows XP desktop, pop-up etheric network adapter hardware equipment dialog box, but even put in the original motherboard CD ,it cannot install the driver. The second day, boot again, can't light system, and with long alarm sound. Troubleshooting: according to general processing ideas, Acer One mainboard long ring because of part of memory error, removed memory, seek to rubber to wipe it, reinsert, booting, still a long ring, remove the memory, separately to insert the memory, one to one test , only one with a ringing voice, but show nothing, another is a long ring. Trying to remove CMOS battery for discharge and so on method but all useless. Memory broken? But the author believes that two may not be damaged at the same time. Thinking the solution, not inadvertently found that when on-board flash lights flashed, sound box has been a regular sound, Should power supply be problem? Examining the power, they found a cooling fan didn't even turn. Immediately seek to another good power supply, replacement to the author machine test, everything is back to normal. Failure analysis: later aparted failure power for check, several filter capacitance already summon up, due to capacitance aging, lead to recharge time too long, so causing boot waiting time too long, and because the bad filtering, thus Aspire One appear afore-mentioned fault. |

why FUJITSU laptop became slowly?
|
People often frustrate for his slow computer, ask what to do to solve it. This article slow detail problems analyzed for a solution. 1.Hardware problems cause computer operation and speed Fujitsu SQU-808-F01 Hardware aging or hardware is not suitable for existing software and system.Hardware after long used, performance will have declined, if once maintenance, so the impact on the performance may be more. In running time can obviously feel computer slow. The solution following has two kinds: (1)Upgrade for hardware, upgrade CPU, memory and the mainboard. (2) change low version of the system or low version software. 2. Hardware damage cause computer run slow Sometimes the Fujitsu SQU-808-F02 hardware damage, such as the motherboard, CPU heat dissipation place and so on such fault will lead to computer performance degradation or can not run normally, need specialized computer maintenance engineer testing. 3. Hardware establishment question reduced computers running speed Hard disk long time used will produce some debris on your hard drive, can first fragments finishing. Secondly, we should check computer other hardware whether is normally Set. Close the computer hard disk compression attributes, unloading when some usb peripherals not in use 4. system setting and software problem causes computer slow (1). Too much start up program Some Siemens Amilo Li 3710 computers too many default start up program, first reduces the speed, secondly in computer operation process have too many no necessary process run in the background, reduce computer speed. Then can input powered up decree, modify, removed unnecessary projects, to a certain extent low speed. (2). The driver not installed properly, or be changed Can use special software drivers to drive new installation or upgrade. (3). Too much Desktop icon and too much special efficiency made computer slowly. Special effects cause and icon file can affect computer speed, reduce FUJITSU Siemens Amilo Pi 3560 desktop icon, and close unnecessary special effects. (4). Some process occupies many system resources Sometimes computer boot time is too long, or some program cause computer system resources anxious, this time can restart the computer or finish software occupy high CPU and memory and open again. (5). Antivirus software or other software problems If antivirus software is running or a virus in the computer system operation can reduce computer speed, then first need to wait for antivirus software scanning finished, secondly, the virus killing was carefully. Generally speaking, the FUJITSU Siemens Amilo Li 3910 battery computer slow is caused by above kinds of problems ,can carefully examined or seek professional computer maintenance engineers for help to solve the problem. |
Why SONY VAIO PCG-5K1L black screen after thunder
|
Recently to a thunderstorm season, there is often a lightning, causing potential safety problems on the computer. Users Wang in using the SONY VAIO PCG-5K1L a few days ago when suddenly a muffled thunder outside the window to be fixed that computer screen, the hard disk light is no longer flashing. Restart the computer boot black screen that the host is not bright lights. Open the box and found cpu, graphics card, power the lights are not bright. After the engineers check the laptop, it was found that the motherboard Southbridge chip has burned scars, while the power is also burned. Had to be returned to the manufacturer for motherboard repair, power supply after the damage after a serious view had to change a new SONY VAIO PCG-5K1L Battery power supply. After such a good motherboard repair, replacement of a good new motherboard and power supply, the computer will not boot black screen in the event of failure, and everything back to normal. When the user must use a computer can not ignore the destructive effects of lightning, to prevent static electricity through the network cable, power cord, airborne, causing damage to the computer circuitry inside the laptop burned and unusable. After a black screen failure after the computer boots, Wang more careful use SONY PCG-5K1L, and a more recent lightning have to unplug the power and network lines, protect the computer's security. |
