by Nick Lai

Quanta Confidential

Agenda• DM3D and DM3L

• No Power

• No Post

• How to debug

• Key signals

Quanta Confidential

DM3D and DM3L• The difference between DM3D and DM3L

– DM3D is using Intel graphics (915GM North bridge, FSB 533MHz)– DM3L is using Intel graphics (910GML North bridge, FSB 400MHz)

• CPU – Banias 400– Dothan 533

• Memory

– DM3D/L is DDRII which is not compatible with DDR. The socket key is different.

• SIO– DM3D/L series are Mac III

Quanta Confidential

DM3D and DM3L• Video

– DM3D/L is Intel graphic

• Cardbus– DM3D/L series are TI cardbus

• LOM– DM3D/L series are PCI bus 10/100Base LAN

• MDC

– DM3 low cost MDC

• Support Express card

No Power• Short

– Capacitor cracking– Metal garbage– PCB– Assembly issue– Bad parts– Burn parts

• Open– Bad parts– Burn parts

• Debug skill (Use Power sequence)– Power switch (the current on power supply)– +3VALW– SUN_ON– Flash and SIO interface.– Thermal protector (U8)– Power good (ICH_PWROK)

Quanta Confidential

No Post• Power level

• Thermal protector

• Power good (ICH_PWROK)

• Clock

• Use debug card

• POST LED

• LCD or CRT no display

Key signals• CPU

– CPUPWRGD– CPURST#– ADS#– CPU_VID0~5– Vref

• NB• VGA

– LCD power or LCD signals– Inverter

• ICH6– ICH_PWR– PLTRST#– PERST#

• SIO– SUS_ON– Most of GPIO

• SMbus• Voltage level

• Review the schematics
