  3. Chapter 1Testing Flow Chart

  4. 1. Pretest Flow Chart Visual Inspection CIDcheck Return to CID process Plug all test tools, run Freedos test program. Rework (ARN) Check R R ARN: Abnormal Request Notice Windows OS Plug in CPU voltage test tool on the CPU socket. Measure CPU voltage (Vcore) R R Turn OFF Power supply Remove all test devices. Plug in Cpu,Ram,port80 Check post code has passed CPU& Memory. R Means Return to RMA or Pass to Repair Engineer. R

  5. 2. Final Test Flow Chart Visual inspection (OQC) OQC: Output Quality Control Rework Check (ARN) Return to engineer repair again, if can’t repair, pass to exchange flow. Plug all test tools, run ASUS test program. Windows OS Test Finished, pass to next station

  6. Chapter 2MB Component Introduction

  7. Input / Output Devices

  8. Get familiar with PC • PC consists of: • Input/Output Devices • PC System • Motherboard • CPU • CPU cooler • DIMM (memory) • Cables (IDE, SATA, floppy, COM, etc.) • PSU (switching power supply) • Add-on cards (VGA, audio, LAN, modem, SCSI, TV-Tuner, video capture, etc.) • System fans • Storage Devices • Externally-accessible (External SATA, USB) • Internal

  9. Inside the PC Case Power Supply DVD/CD/RW System Fans CPU Memory Cables Motherboard Add-on cards Hard Disk

  10. MB Socket type Different socket type

  11. MB Socket type Different Type of CPU Intel

  12. MB Socket type Different Type of CPU Intel Socket 478

  13. MB Socket type AMD Different Type of CPU AM3 Socket 754 AM2 754 939 940 938(AM3)

  14. Motherboard Components • Motherboard is composed of: • PCB : printed circuit board • chipsets : North bridge + South bridge • internal connectors(CPU, memory, floppy, IDE, power, add-on cards, etc.) • external connectors(USB, PS/2 keyboard & mouse, RJ-45 LAN, parallel (line printer), serial (COM), game/MIDI, audio I/O, etc) • headers(fans, audio input, LED, switch, USB, WOL, WOR, thermal sensor, etc) • BIOS(Basic Input/Output System) • ICs, Resistors, Capacitors, Inductors, MOSFET, Battery • jumpers / DIP switches(host-bus frequency, CPU multiplier, etc.) • Others • All these on-board components could be split into two categories: • SMT (surface mount technology, or SMD – surface mount device) • DIP (dual in-line pin) packages

  15. Introductions • High-speed • North-Bridge: • CPU • Memory • AGP/PCIe • Mid-speed • South-Bridge: • PCI, PCIe • IDE/SATA • USB NB SB • Low-speed • LPC Super I/O: • KB/MS/FDD • COM/LPT • ROM BIOS SIO
