Battery Review and Tips

If there is no electricity supply, check the electricity situation of PC power supply interface and power supply line

1. Check the chassis power interface and power lines, is intact. If the interface and power lines are damaged shall be replaced broken;
2. Check the motherboard power cord jack. If not broken, it will pull out and then insert the jack. General can be solved, because the motherboard is bad the situation led to no electricity;
3. Check the switch on the chassis FUJIFILM np-40 battery power supply to see if it is properly connected with the motherboard. Check the jumpers on the motherboard, find the control power of the jumper, try to cut short the jumper pins, if the motherboard can operate normally, which indicates that the jumper has been a problem. Mainly due to the jumper pins and the jumper cap is bad. Cut short jumper pin can make the full coupling between the two.

Electricity supply OK but still black screen

1. Check all of the cards, graphics cards, sound cards, CPU, RAM is installed in place, if good contact is stupid way is to pull out them, and then re-insert in. Check all interface cards and interface is good contact. The benefits of this treatment is a blank screen, one by one eliminate the problem, they would rather kill a thousand, not given a statement or a purpose is to examine the issue.
2. If the issue is too serious to have to use the most cruel trick, unplug all the minor nature of the original parts. Disconnect all the secondary sexual power lines, including the IDE floppy drive and other equipment. All you need is the most basic initial startup screen memory self-test data. Motherboard, CPU, RAM, graphics card and so on. If the test passed. One by one add other components to add a self-test once. If the test pass, you find a problem, which is not properly installed or not compatible with other issues to be solved.

Check the general steps:

1. Open the case, first check the BIOS reset pins.
2. Just insert a memory, try several times, usually memory problems. Memory problems may or may not self-police, the best by a good memory test, or the memory into the CASIO np-60 battery machine on the judge friends.
3. Startup floppy disk, hard disk light is not on the motherboard may be bad.
4. Memory self-test passed, floppy drive, hard disk indicator light, will not start.

Restart the machine, press the F8 key to enter safe mode to see if it can be easy to handle, the system can be restored. Not to use the DOS boot floppy, see if you can access the hard disk, can enter to see if you did GHOST backup clone, and some machine factory to do a good job, could not get to format the hard disk reinstall system.

Computer black screen troubleshooting

For computer processing basically excluded black, replacing the combination of methods, the principle should be replaced in a suspicious rule out the biggest part. For ordinary computer users is concerned, lack of expertise, can cause failure analysis, follow these steps to make your own troubleshooting.

First check the contact is good. Check the video card and monitor, respectively between the contact is good, the graphics card and motherboard I / O is good contact between the slot if necessary it can be removed and re-install time, ensure that the installation place, a good contact. If the access is no problem, it is best to replace a monitor to try to identify the monitor, no problem. If the monitor is no problem, view the cpu fan is running, such as running, with a multimeter measure the voltage output is normal for the ± 12V, ± 15V, if not normal to try for a Acer aspire 5720 battery power supply.

If still a blank screen, then remove the components installed inside the computer, leaving only the cpu, video card, memory, you can limit the cause of the malfunction cpu, motherboard, memory, among the three. General If the memory is faulty, the alarm should sound. If you exclude the memory failure, and only the cpu and motherboard. For a normal cpu (should be compatible with the detection of computer), start re-testing, if still a black screen appears, you can only change a motherboard, the question should appear on the motherboard.

Computer black screen computer failure may indicate more serious problems exist, it may appear black in the phenomenon to be excluded by the above method. Should be flexible in processing applications excluded, substitution method for the timely processing phenomenon to be eliminated.

1. When the display is blank no image is displayed (the display currently on the market, but no signal sent to the host, the screen will display “No signal cable”), first check the host power is a good plug, power supply fan spins? Host panel power indicator, whether the hard disk light is flashing light? If the system does not work because the power supply or motherboard no electricity, the monitor signal is received in the absence, of course, there will be no image displayed.

2. Check the monitor and then plug the power supply is good? If your monitor’s power switch is a touch switch, when you power up the monitor, you should hear a slight “provision pop” sound, then the monitor can determine the switching OLYMPUS li-40b battery power supply circuit is good. Then the monitor’s power switch is turned on? Monitor power light is lit? When the hand near the display screen and move it slowly there hissing sound, while the hair on the hands of the feeling of being sucked, which checks the monitor is working the high-voltage circuit.

3. If it is determined the display has been added to electricity, and there is high pressure occurs, continue to check the monitor cable connector and the signal output interface card is a good contact? Are there loose? Unplug and then check, D-type interface for bent or broken needles or have a lot of dirt. This is a problem often encountered in many users, when connecting the D-type socket, non-uniform force, or forget to tighten the screw interface, the interface to loose cause bad contact, or because of improper installation or excessive force, so that D There are needle-type interface, or a curved needle, resulting in poor contact.

Note: the data display 15-pin plug may have a shortage of needles, such as 4,9,11-pin, then normal, do not artificially supplemented by other wire to pin these missing bits, so as not to cause other problems.
1,2,3-pin for the red, green and blue guns signal input, if any of you bad needle contact with the MOTOROLA GP340 battery screen there will be lack of appropriate color. If the first pin 12,15 there is a problem, the host can not find the appropriate display, but this does not affect use. If the first pin in question 13,14, the display will appear black, the display lights in the boot from green to orange after a while. Also appeared in one of the black screen.

4. Open the case to check the display card is installed correctly? Is in good contact with the motherboard slot? Video card or slot is too long and the use of too much dust, as well as causing poor contact? Whether the chip on the graphics card burned, traces of cracking. When the causes for black screen graphics, the computer POST a short time that is four long beeps prompt. Installing graphics card, graphics card to hand hold the upper part, even forced into the slot, so that the screw graphics port and port match the main chassis of the screw. Do not force plug is not fixed, resulting in distorted graphics. If the confirmation is installed correctly, you can remove the card wipe with alcohol cotton ball for about pin cheat, or a slot (only for PCI cards) installed. If does not work, can only be a good graphics card for a try the next. If that does not, in determining the graphics intact, they must also consider the graphics card and motherboard compatibility.

5. Check the other boards (including NIKON EN-EL14 battery sound cards, Decompression Card, video capture card) slot on the motherboard is good exposure? Note Check the hard disk drive data cable and power cable connection correct? Replace other card slot, cleaning pins. This is often easy to overlook many people. Generally believed that black screen computer monitors and graphics cards is the issue, and other device-independent. In fact, because the sound card and other equipment is not installed correctly, cause the system to be completed in early to make of the difficult, especially in the hard disk drive data cable and power cord to the wrong, the fault likely to cause no display.

6. Check the memory is good contact with the motherboard? Reseat the memory or try another slot, or the replacement of the memory. If the memory problem, the computer starts, there will be a continuous rapid beeps. Tone varies because of the motherboard.

7. Check the CPU and the motherboard CPU Block access to well? Due to moving or other factors, the battery shop CPU socket with the SLOT1 jack or SOCKE370 bad. Best removed by hand pressing a CPU or CPU and then re-install again.

8. Check the CPU FSB, multiplier, memory frequency jumpers or CMOS settings are correct. Motherboard manual control, one by one check the relevant jumper, the order of “CPU FSB Frequency Jumper Jumper-CPU – RAM frequency jumper.”

9. Check the CPU voltage is set properly. Set CPU voltage jumpers to be careful with the CPU must match the operating voltage. VIII and IX to this two-step assembly machine or like some overclocking black screen appears when the user double-check.

10. Check the CMOS parameter settings are correct. If your computer is equipped with two graphics cards in your CMOS settings is the first initialize PCI graphics card, and your only monitor connected to the AGP graphics card, of course, the display is not bright.

11. Check the host and display the required whether the work environment? Voltage is normal, the ambient temperature is not too high. In addition to checking the above steps, but also the working conditions according to the computer to quickly locate, such as the power is turned on the host, you can hear the beep is heard that the computer self-completion, if the hard disk light is constantly flashing at this time, it should be In the second step to the fourth step checks.

12. If the monitor in the universal laptop ac adapter computer displays the contents of the startup process, only after loading WIN98 black screen when the screen, which is WIN98 system software problem.

The inspection method is based on the display itself has no electrical fault, that is, the power the host turned the monitor’s power indicator light from green to yellow, but did not display a black screen image display. If you use these steps to display still no display, should be invited to professional maintenance.

● crashes caused by excessive disk fragments

Symptom: a 486 compatible computer, the configuration of marine Hippo-10 motherboard, Intel 486DX2/66 CPU, 4MB RAM, Trident 9440 video card (VESA bus, 1MB display memory), Techmedia color monitor, Seagate 120MB hard disk, run the DOS program everything is normal. An accidentally deleted a file in Windows directory after, Windows failed to start, delete the Windows directory and then reinstall Windows, Windows Setup when there is the word, the Dell XPS M2010 battery system crashes, can not continue the installation.

Troubleshooting: At first I thought the system for viruses, the use of KV200, KILL, and other anti-virus software failed to find the virus. After the suspect is a problem with Windows installation disk, replace the Windows installation after-hours, the failure remains. Because the machine running DOS applications under no problems, thus excluding the possibility of hardware failure. Loaded the Windows machine has been destroyed several times, re-install all previous no problem. Is not due to a sudden thought caused it to install Windows again? Norton’s Disk Doctor run external laptop battery NDD, it was found that there are many on the hard disk lost clusters, repair, and later under the order to run DOS disk tools for De-frag, there are many fragments found on the hard disk, the overall order after re-install Windows, completed successfully.

Summary: Installing Windows, to open up a space on the hard drive as the Windows of the permanent or temporary swap space, when the hard disk fragments are too many, cause crashes. The repeated failure is due to the hard disk copy, delete files, resulting in a large number of lost clusters and fragments caused by too much. Therefore, installation of large-scale software such as MOTOROLA GP340 battery Windows, we must first defragment the hard disk, hard disk space for a row to open up Windows or other applications.

● Short-circuit caused by the host local hard disk can not start

Symptom: a GW386 computer, open the panel every time the power switch, power LED flash Jimie, the machine can not cold boot.

Troubleshooting: from symptoms of view, suspected to be the host switching power supply is faulty and, therefore, the normal host another of the same model with the fault plane switching power supply swap. Turn the power switch, the normal machine still boot, and fault plane fault still shows switching power supply itself has no faults. Judgments based on experience at this time, the failure may be due to the three load switching power supply, the motherboard, floppy and hard drives there is a short circuit failure, which led to the implementation of switching power supply output short circuit protection. Were broken motherboard, floppy drive, hard disk boot, found short-circuit fault from the hard disk. The failed hard drive (model WDAC280, capacity 80M) from the host, remove, with 500 meter from the hard disk on the DC power outlet measurement +5 V and +12 V to ground resistance (with a 1K file and the red pen ground, black pen then +5 V and +12 V), and with the same SONY NP-FW50 battery model to compare the normal hard disk and found that the hard disk +12 V to-ground fault resistance 700Ω, while the normal hard drive +12 V to-ground resistance is 3.2K, +12 V hard disk failure can be seen to exist on the local short circuit. Carefully checked and found a sheet of horizontal polarity capacitor C65 burnt charcoal, found on the hard disk from the normal capacity of this capacitor 22μF/25V, due to the market difficult to purchase, the capacitance of this shape, it is the same capacity with an aluminum electrolytic capacitors instead of welded, heavy +12 V measuring resistance to ground has been restored to 3.2K, installed hard drive, turn on the power switch, indicator light, the machine self-test, troubleshooting.

Symptom: My computer configuration is Intel million new motherboard, AMD K5-100 CPU, Seagate 850M hard drives, 9680 video card, Sony six-speed CD-ROM drive, often following the last month some of the strange phenomenon:

1. In DOS, when you play the game often crashes (crashes frequently occurred in the 20 o’clock to 11 o’clock, after 11 if not crashed), crashes when the keyboard is blocked, but the mouse cursor can be moved;
2. Use any other HP elitebook 8530p battery software crashes after a few minutes, less than 2 minutes into the Windows 3.2 will automatically return to the DOS, the screen prompts: “Windows Protection Error # 14 You may need to restart your computer”;
3. With non-toxic floppy disk, and then use the hard disk of the software or play games, the fault remains.

Repeatedly checked with a variety of antivirus software and found no virus, there is important data because of the hard disk, do not want low-level formatting the hard disk. May I ask what is the reason? Is a hardware problem or update the virus in trouble?

Troubleshooting: in a variety of computer failure, the crash most common cause of the malfunction is also the most complex. Once in a crash may be due for some random reason, not necessarily in troubleshooting, but belong to frequent failure of the crash. Variety of software and hardware problems can cause a breakdown, and should therefore be to analyze specific issues.

Question about the “floppy disk with a non-toxic, and then use the software or playing games OLYMPUS li-42b battery hard disk, the fault is still,” I understand to use the software on the hard disk fails, the use of the software on floppy disk crash will not occur. If so, consider the hard drive should focus on the issue. Hard disk failure can be both caused by the software may also be caused by hardware. Software are two main reasons: the virus and the software itself is defective. As has been repeated by various anti-virus software, check and found no virus, you can temporarily excluded. Software itself is defective, such as the file is damaged, improper installation can cause crashes, but generally not all of the software problem. The “minutes after using any other software crash,” so the idea of ​​the software itself can be defective temporarily excluded. That can not consider problems in the software, the main reason for considering the hardware. From the hardware side, can be considered from the following:

1. The hard disk parameters are set incorrectly or changed, the main check:
• Hard disk mode select LBA, Large, Normal, your hard disk is 850M, LBA or Large mode can only be elected;
* Block mode select Enabled, Disabled;
· MOTOROLA HNN9008A Battery PIO mode select 1,2,3,4, if the original set to 3 or 4 to 1 or 2 might reduce the transmission rate of a try.
2. Reduce the DRAM burst read and write time (Read / Write Burst Timing). For example, from X222 to X333, or replace the memory, try again, because the hard drive and memory to be frequent exchange of data between, with good will crash.
3. Taking into account the “Death frequently occurred in the 20 o’clock to 11 o’clock, after 11 will not crash if the” should check the power output is stable. 8 pm to 11 o’clock the general low mains voltage, if the poor performance of switching power supply, the system is not working properly can lead to crashes.
The above analysis is based on the floppy disk to work properly under the conditions. If you are running the same software on a floppy disk crashes, the problem is not necessarily out of the hard drive. At this time should be the main consideration is the CPU chip and memory working properly. If the CPU cooling fan does not work, resulting in CPU chip temperature is too high, will inevitably lead to crashes; memory will cause a breakdown of poor quality; but also to check the stability of the output switching power supply, normal. In addition, do not rule out the battery shop graphics card is faulty (show poor cache performance) due to crash failures, which can be confirmed through the exchange to check.

1.CPU, graphics cards and other accessories do not overclock too high, pay attention to the temperature, otherwise, when you start or run mysteriously restart or crash.
2. In the replacement of computer accessories, be sure to plug it, because the bad parts will cause the system to crash.
    3.BIOS set to be appropriate, although the recommended BIOS settings for the best, but not the best so-called best and sometimes the best set up actually started or run crash cause.
    4. Preferably with power supply in order to avoid voltage instability caused by crashes.
    5. If able to do so, the installation of a UPS, so power outages will not cause computer crashes.
    6. On the floppy disk and vgp-bsp13/s battery CD-ROM unknown, Do not use on the E-mail attached to the software, use the KV300, Rising antivirus software, etc. Check before use to prevent transmission of virus, is a system crash.
    7. In the end application is not normal, do not turn off the power, otherwise it will cause the system file is corrupted or missing, causing auto-start or run in the crash. For Windows98/2000/NT other systems, it is very important.
    8. In the installation of application software which, if the dialog box prompted “Overwrite File”, the best choice not to cover. Because the current system file is usually the best, not according to the time the decision has to overwrite the files (unless you are very concerned about the time of the file.)
    9. When you uninstall the software, do not remove shared files, because some of the shared file system or other programs may be used, once you delete these files, applications will not start the crash, or run a system crash.
    10. Set the hardware device, it is best to check for the interrupt number reserved (IRQ), do not let other devices use the interrupt number, or caused by IRQ conflicts, which cause the system to crash.
    11. In the loading of certain software, pay attention to the order, because some non-standard software programming in the first run is not ranked, but to put the last run, so as not to cause the system to manage the chaos.
    12. In running large applications (such as OFFICE 2000), do not exit before running the program is running, otherwise it would cause the collapse of the Windows98 system.
    13. In memory is smaller (such as 4MB-16MB SONY NP-FW50 battery), it is best not to run large memory for applications, or prone to crash at run time. Recommend running these programs save time when the file is currently in use.
    14. For the system files or important documents, it is best to use hidden attributes, so that and avoid Erased or overwrite these files.
    15. To modify the hard disk master boot record, the best to save the old record, to prevent the failure can not be restored because of changes in the original hard disk master boot record.
    16. The best use of beta software, because the beta is not stable enough in certain aspects, the system will not start after use.
    17. In Windows95/98 as much as possible not to run 16-bit applications, because the 16-bit applications with the Windows 32-bit applications in the conflict, which led to crash or not start.
    18. BIOS upgrade, you should determine the BIOS version of the upgrade, and should be kept about the original version, so as not to upgrade the error that the system can not start.
    19. Try not to use pirated software because the software hidden in a large number of viruses, if implemented, will automatically change your system, the system crashes in the operation.
    20. In the chassis, may contain a large amount of dust, the dust if exposed parts of the circuit, make the system unstable or crash.
    21. In the implementation of the time defrag, do not run large software applications, or cause crashes.
    22. With the antivirus software to check the hard period, do not run other applications in order to prevent system crashes.
    23. In the Internet, do not open too many browser windows once, leading to lack of resources, cause crashes.
    24. In the Turn off the computer, do not directly use the power button on the chassis, because the direct use of the power Inspiron 1545 battery button will cause the loss of files, so the next time does not start properly, resulting in system crash.

The above method, I believe we will have some help, sometimes to specific circumstances take different measures, must not be applied mechanically Oh!
