1. The computer system time is not allowed
The fault phenomenon ? a use for a long time, every time after start compatibles system of time from January 1, 1998 when start
The failure analysis and processing ? is commonly BIOS can automatic charging and, therefore, appear this kind of failure of the main reason may be that CMOS cell damage, only need to change CMOS battery, failure will be ruled out.
2. Hard disk cannot read or write floppy drive
The fault phenomenon ? a computer boot floppy self to the floppy drive light, but prompt floppy drive not found. Disk boot normal start but they could not read/write floppy drive.
The failure analysis and processing ? first suspect may be the floppy disk is damaged, so will the floppy drive off to another on a computer but use normal, change another good floppy drive to the computer, still appear the same fault. And doubt multi-function card is damaged, but will the card to the other computer test is no problem, with a good multi-function card be replaced, the fault still exist. And he doubt mainboard failure, and most likely damaged is BIOS chips, replaced by substitution method, found that the BIOS and no damage, finally will only on the mainboard take the CMOS power battery, and the information in the CMOS completely lost, then the information reset, fully recovered;
3. After the boot prompt A drive, B drive configuration type error
The fault phenomenon ? A A drive, B drive are using computer, A drive for the use of 1.44 MB of floppy disks floppy disk, solid B for the use of 1. 2 MB of floppy diskette. CMOS the configuration content is completely correct, but the boot does suggest A drive, B drive configuration type error.
The failure analysis and processing ? double-check CMOS configuration content were not found any problems, floppy drive and multi-function card replacement also has no problem, then doubt CMOS infection, each main board after discharge to configuration, also did not solve the problem. Then try in the configuration information will be two floppy drive type to other types, when two floppy drive are changed to 360 KB floppy drive, boot floppy disk error no longer hint, this situation may be due to the communication line connection floppy drive has a problem to change a communication line after fault,
(4) failure in use floppy deny floppy disk
The fault phenomenon ? a computer in use process on the diskette to read/write operation, the following tips:
General Failure Reading Drive A: Abort, Retry, Fail?
The failure analysis and processing ? the situation belongs to faulty equipment, if choose A said quit, R, F to try again for failure to other driver, cause the wrong reason mainly has the following kinds:
Floppy disk and floppy disk capacity is not compatible
Use DOS command the read/write floppy disk, need to consider the floppy disk and floppy drive compatibility. If it is 720 KB floppy drive, and add to the is 1.44 MB floppy disk will appear the tooltip but 1.44 MB 3.5 -inch floppy disk can normal read/write 720 KB and 1.44 MB two floppy disks. Also, 1.2 MB 5.25 -inch floppy disk can normal reading and writing 360 KB and 1.2 MB two floppy disks, the return is not;
The floppy disk boot sector damage
Due to the virus or other improper operation make the floppy disk boot sector damage, read/write disk read will appear error, can use tools to floppy disk repair;
The software of the floppy disk no formatting
For DOS can giving disk format is divided into some sector of the disk, not formatted diskette cannot undertake the read/write operation. For not formatted diskette to read/write operation, the tooltip. As long as in the DOS or system disk format again after the read/write operation can;
In CMOS floppy disk type Settings
In CMOS storage in the computer normal work the equipment parameters setting, if the parameters in the CMOS Settings, in the operation equipment will also appear afore-mentioned problems, if is 1.44 MB floppy drive, and in CMOS is set to 720 KB or 360 KB, etc., the read/write 1.44 MB floppy disk, namely will appear afore-mentioned error;
Tip: in the CMOS the floppy drive set to "NOT INSTALLED", then into the read/write disk, there will be no floppy disk tips, as long as in the CMOS Settings to recover normal floppy Settings, this problem will NOT appear;
5. Start the computer can't detect floppy drive
The fault phenomenon ? start computer, display "Floppy disk (s) fail (and)" error message information;
The failure analysis and processing ? appear Floppy disk (s) fail (and) "or A: drive error messages, said motherboard BIOS check less than the Floppy disk hardware, the majority is Floppy drive hardware failure caused by, the specific solutions are as follows:
Check on the main board of the floppy disk interface and floppy drive data and the power cord, if have not found the problem, and can be connected to other computers on the floppy disk test, if the floppy disk to use normal can check CMOS on floppy drive Settings, check the CMOS "integrated Peripherals", "onboard Fdc Controller" item will be set to "Disabled", if the situation changes set to "Enadled" can debugging;
6. Floppy drive lamp has not been bright
The fault phenomenon ? after boot, appear "Floppydisk (s) fail (and)", and floppy drive lamp has not been bright, changed some BIOS setup after also of no help. The floppy drive to the other place can be normal use, the new floppy drive in this computer is not bright light.
The failure analysis and processing ? reproduce the fault mainly because of CMOS setup wrong, floppy drive's power supply cord doesn't work. The solution is: boot press [Del ? button to enter BIOS setup Settings "INTEGRATED PERIPHERALS", and "Onboard FDC Controiler," this option set to "Enabled" can.
7. Can't write data to a floppy disk
The fault phenomenon ? floppy disk will protect mouth is open, the floppy disk still can't write to the data
The failure analysis and processing ? the correct reading data, case can be ruled out the possibility of failure there floppy drive hard. But at system startup into the CMOS setup, check "Floppy access Contrl" (Floppy disk access control) will be set to "Read - only", so it will be "Read - Write" troubleshooting.
8. CMOS setup error caused by hard disk failure
The failure analysis and processing ? the CMOS hard disk type is correct or not directly affect the normal use of hard disk, the present computer can support "IDE Auto Detect" function, can automatically Detect the type of hard disk. When hard disk type mistake, will appear unable to start the system or the occurrence of the read/write error. The hard disk type such as CMOS is less than the actual hard drive capacity, the hard disk back sector will not be able to read/write, if is more for the individual state of area division will be lost.
In addition, because has IDE support logic parameter type, hard disk can use Normal LBA, large, etc., if the three modes of installed the data, and abundant CMOS will for the rest of the way, the hard drive assembly will happen/write error, because the mapping relationship has changed, will not be able to read the original correct hard disk position.
9. CMOS due to a hard disk boot failure caused by electricity
The fault phenomenon ? the computer after startup screen prompting "Device error" prompt.
The failure analysis and processing ? this is mainly due to the CMOS due to electric cause information loss abundant up. Right according to the following approach: first open the case, observe whether the battery loose. If it is, it will be fixed to start; If not, may be the battery failure, in block good battery, resetting CMOS parameters, hard disk can normal launched.
Tip: if you can't the normal starting, should be due to the data cable joint reverse cause.
10. The old Type parameter error caused by hard disk failure
The fault phenomenon ? host is started, the inner self, the two "beep" sound horn ring, screen appears: "the C: Drive error" error translation piece, hard disk can't start with floppy disk boot success, tried to get into the hard disk, appear: "Invalid media type reading Drive C Abort, Retry, Fail?" Error messages.
The failure analysis and processing ? : appear this kind of circumstance is due to the hard disk parameters Type value does not match the cause, Type meeting is a hard disk feature mark, on behalf of hard disk capacity size, head count, head count and sectors equivalent. If the value of the Type set wrong, the hard disk can't start, the solution is to set the hard disk Type value.
After the boot for self start, press XPS M170 Keyboard ? DEL ? key or at the same time, press the ALT + CTRL + ESC ? key combination, can enter the host parameter table, DriveC: (drive C:) columns of the "Type" items, input the correct Type value can be
11. The hard disk suddenly can't guide system
The fault phenomenon ? a used 3 years compatibles, suddenly there was a boot: "Disk boot failurt, Insert system Disk and press enter" clew cannot lead system.
