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
