Knowledge: Computer switch err r analysis!
[Performance] boot failure normal self test is complete, there “DisketteBootFailure” message, can not enter the system. [Failure Analysis] appear in the message, because the boot floppy disk for errors, cause the system fails to start, as long as the replacement boot disk in the floppy drive to start the system. [Troubleshooting] to resolve the failure, the system starts normally, according to the following steps. ⑴ If the machine does need to boot from the floppy, then use a normal boot disk to replace the damaged boot disk, restart the computer. ⑵ In other cases, the user forgot to use the floppy disk out, and the CMOS and set the floppy drive as primary boot device. In this case, restart the computer an error message will appear, this time only the floppy disk out and press the Enter key to start the system from the hard drive. ⑶ order to avoid future recurrence of similar situations in the CMOS settings into “BIOSFEATURESSETEP” setting option, move the cursor to “BootSequence”, press the “PageDown” or “PageUp” key is set to start “C, CDROM, A “(that is, the C partition, floppy drive and select the boot device order). Then press “F10″ key to save and exit, restart the computer. [Show] the machine POST failure occurs after “Master (\ Slave) None” message, can not enter the system. [Failure Analysis] with an IDE data lines to two IDE devices must be correctly set the primary slave, or there will be “Master (\ Slave) None” error. [Troubleshooting] to resolve the failure, in accordance with the following steps. ⑴ check the data line two IDE devices (such as hard disk or CD-ROM), according to the prompts on the device, two devices were set as master and slave, restart the computer. ⑵ IDE device jumper setting need to pay attention, start with an IDE hard line should be set for the main equipment, or system to not start. [Performance] POST failed, the emergence of “Harddisk (s) drivefail” message, you can not normally enter the system. [Failure Analysis] we can see from the error message is hard disk malfunction, leading to not start the system. May be due to the hard disk is not connected properly, or because of problems with the hard disk itself. [Troubleshooting] To solve the hard disk failure, through the following solutions. ⑴ check the hard drive data interface, data interfaces to ensure that no damage, and carefully check the hard drive power connector, check for loose power. ⑵ exclude the data and power interface problems, if the fault is still not resolved, you will need to drive to get the other machines tested to determine whether the fault for the hard disk itself. [Performance] system startup self-test failure, the emergence of “BIOSROMChechsumerror, Systemhalted” error message, unable to enter the system. Restart the system again, there is still the same error. [Failure Analysis] the message that the BIOS check error is found, it may be due to BIOS update failure or accidental damage caused by the motherboard BIOS. Actually received sacrificial victim wash hate Ken paternity Guo gingival dream trip Di pepper sand barrier Minato umbrella ㄍ BU!? ⑴ If you have just to update BIOS, restart prompt will appear in the error message, the fault is likely to be a failure by the flash BIOS caused. Typically, the motherboard needs to be refreshed after the failure to the repair location specified by the manufacturer, unless the motherboard has dual-BIOS boot, you can refresh fails, start the system with a backup BIOS. ⑵ if the error is caused due to flash the BIOS, then it may be because the motherboard BIOS for some unexpected damage, in this case, also need to specify the location of the motherboard to the manufacturer for repair. [Performance] POST failed, the screen suddenly “CMOSchechsumerror-Defaultsloaded” error, and gives “PressF1continue, Deltoentersetep” message. [Failure Analysis] The error message the CMOS test error, and prompted to press “F1″ key to start the computer, or press “DEL” key to enter the CMOS setup program. This failure, mainly because the CMOS battery is low, leading to a serious configuration errors. [Troubleshooting] to resolve the failure, can be completed by the following method. ⑴ Follow the prompts, press “F1″ key to enter the default CMOS settings, the computer continues to boot into the system, and then restart the computer, check the fault elimination. ⑵ failure after you restart the computer if not eliminate, the interruption is not caused by the CMOS settings wrong. Is very likely because the CMOS battery problem or low battery, need to replace a new CMOS battery. [Performance] POST failed, the screen displays “CMOSSystemOptionsNotSet” information and can not enter the system. [Failure Analysis] The data stored in the CMOS damaged or missing, the error message will appear. Just enter the CMOS setup program to re-set accordingly, you can solve problems. ⑴ restart the computer, press the “Del” key to enter the CMOS setup program, select “LOADBIOSDEFAULT” option and press Enter. ⑵ in the pop-up prompt box, enter “Y”, then press the Enter key parameters into the CMOS default settings, rebooting. [Performance] [failure] POST screen every time “CMOSBatteryStateLow” error message, and gives “pressF1continue, orDELtosetep” message, press “F1″ key to enter the system properly. [Failure Analysis] the message that the CMOS on the motherboard used in battery is running out, to remind users to replace batteries as soon as possible. [Troubleshooting] to avoid a repetition of the message, according to the following solutions. ⑴ to buy a high quality CMOS battery, the CMOS battery on the motherboard replaced the original, restart the computer will no longer appear in the message. ⑵ If after some time, the message is still there, one could buy a battery is the problem. Another possibility is that the motherboard CMOS power supply circuit leakage phenomenon, which requires the board to the vendor maintenance. [Performance] boot failure, the prompt “CMOSChecksumFailure” information. [] CMOS failure analysis and processing parameters are saved will have a code value. This value is used for error checking, if the read value and the value does not match, then this error message. To resolve the failure, need to properly set up BIOS. [Performance] boot failure, the prompt “CMOSTime
