  29. Repairs and Re-Setting System PC Module 4 • For the type of ATX If the power switch is turned on or the power cord dicolokkan, the fan still, all in the socket when the voltage is measured with a voltmeter will be zero, except the pin 9 is +5 V as a voltage source at the position stanby. If pin 14 is connected to the right with a 9 pin cable, the fan will rotate, voltage on each pin socket 20 when measured with a voltmeter as shown in the table is 3.2. Especially for power good signal when measured with the voltmeter akan bertegangan +5 V down momentarily and then be near 0V when power is turned on. Melakukan perbaikan dan/atau setting ulang sistem PC

  30. Repairs and Re-Setting System PC Module 4 • Likelihood of Damage Total dead (no output voltage on all pins) Voltage output is not stable +12 V output voltage greater +12 V output voltage drop No output voltage +5 V There is no signal voltage on the power good Melakukan perbaikan dan/atau setting ulang sistem PC

  31. Repairs and Re-Setting System PC Module 4 • Procedure and troubleshooting • Check the existence of the voltage source from net, if there is no (meaning there is damage to the voltage source / fix dead jalajala / wait for life), Melakukan perbaikan dan/atau setting ulang sistem PC

  32. Repairs and Re-Setting System PC Module 4 • Check the power cable and connectors with a multimeter. If the row to drop out / replace the cable that is still good, • Check whether the fan rotates, • Check all the pins on the DC voltage output connectors, • Check the switch on / off the power supply. • Check soldiran, path, connection components, and electronic components (active components: Dioda, transistor or SCR and pasip components: resistor, capacitor, PTC, fuse). Melakukan perbaikan dan/atau setting ulang sistem PC

  34. Repairs and Re-Setting System PC Module 4 Troubleshooting Keyboard Keyboard some keyboard models, namely: • 83-Key PC Keyboard • 84-Key AT Keyboard • 84-Key Space-Saving Keyboard • 101-Key Keyboard • Other Keyboard Styles Each button / key on the keyboard with the IBM declared a four: • Characters shown on the surface of the cover lock • Character code of each character key cover • The lock code reading • Decimal place of key figures Melakukan perbaikan dan/atau setting ulang sistem PC

  35. Repairs and Re-Setting System PC Module 4 • Keys on the keyboard may be delayed or does not work because: • Clog sewage • The switch plate or per weak • Track dropouts • Damage to the chip that is inside • To overcome this, the keyboard needs to be treated in a way: • avoid the entry of dirt and animals to the keyboard • to provide adequate air circulation on the keyboard • If interference occurs, the steps that must be made, namely: • remove the cover lock • clean up all the dirt is in • improve the per plate or a key subject • close the back cover lock as

  36. Repairs and Re-Setting System PC Module 4 • Keyboard Troubleshooting • Checking the general functions of the keyboard are: • Check the switch ¬ XT / AT (switch must be in a position for connection to the AT-AT system) • ¬ Check the keyboard lock on the front panel system is in open condition • ¬ Check cable connection and the keyboard is connected properly with the system board. Connections that are less well will cause problems. • ¬ Check glowing LED on the keyboard during the power on whether to flash

  37. Repairs and Re-Setting System PC Module 4 • Possible Damage • Keyboard does not operate a full • Some of the key does not work • The key is broken or depression • The keyboard interface • The keyboard connector • The keyboard cable

  38. Repairs and Re-Setting System PC Module 4 • Procedure and troubleshooting • The keyboard on the keyboard Mikrokontroller, soldiran passive components on the keyboard dry, the PCB on the keyboard to drop out. Or can be also caused by a series of interface units in the system is broken. To isolate areas of damage can easily be done in a way to connect the keyboard to either the unit system, the problem disappears if the damage to the keyboard and if not then the damage to the set of interface units in the system. • The logic pendekode row or column in the keyboard or the line dropped out or PCB soldiran dry or casual contact. This problem can be solved with the keyboard is good. • Apear drop out or switch depression. For that need to be replaced. • The keyboard on the motherboard chipset. To change this chipset IC (SMD IC) or replace the motherboard is good. • Damage due to dropping out or interested in the frequency of use. To replace the keyboard connector. • USB keyboard dropouts checked with the multimeter, and then to.

  39. Repairs and Re-Setting System PC Module 4 • Use Diagnostic Software • For testing the function can use the software keyboard checkit, • QA plus, PC tools, and Norton utilities. Facilities provided in this software is not checking the button is pressed or the lock-key keyboard.

  40. Repairs and Re-Setting System PC Module 4 Troubleshooting Floppy Disk Drive or Hard Disk Possible damage Damage to the floppy disk drive ¬ The system displays the disk directory is not suitable ¬ The system can not be read from all drives ¬ wrong when reading floppy disks written on a PC the other Damage to the hard disk ¬ The system can not booting from the hard disk ¬ disk performance decreases Melakukan perbaikan dan/atau setting ulang sistem PC

  41. Repairs and Re-Setting System PC Module 4 • Diagnostic procedures and trouble shooting floppy disk drive • When reading the system disk in the floppy drive first, the information on the FAT and root directory will be copied to memory. • A copy of this disegarkan akan reading the content of the diskette in the new. Replacement diskete line modifier resulted in changing the disk. If this type of problem occurs, check jumpers setting on the modifier line disk. • Check the data cable and power (check the LED lights a flame in the drive) • Head dirty drive (clean the drive head with the cleaning head) • Possible damage to the series of logic drive (try to replace the drive with another) • Possible damage to the controller (try to change the other controller) • Due sesuainya not format the drive or disk is not appropriate. Try reading the other floppy disks. Melakukan perbaikan dan/atau setting ulang sistem PC

  42. Repairs and Re-Setting System PC Module 4 • Diagnostic procedures and trouble shooting hard disk • ¬ settings in the CMOS drive type does not match or lost (run SETUP and autodetect the hard disk type) • ¬ corrupted boot track (re-install the boot track using the command SYS) • ¬ BUFFERS in CONFIG.SYS is set too small (add / increase the value of BUFFERS in CONFIG.SYS) • ¬ SCANDISK Run program to manage data in the hard disk. • ¬ Interleave does not fit (do low-level format) Melakukan perbaikan dan/atau setting ulang sistem PC

  43. Repairs and Re-Setting System PC Module 4 Evaluation • What steps are needed to ensure that the conditions peripherals remain in good condition? • Corrective steps which needed to be damage to the peripherals is not extended to the other peripherals? Task ! • Read the Instruction Manual of each equipment • Make improvements to the summary procedure of the respective peripherals. Melakukan perbaikan dan/atau setting ulang sistem PC
