Battery Review and Tips

● 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!
