Note This page is a technician's reference. You will need Schematic and/or Boardview files to follow these steps. |
Note On Corona, Waitsburg, Stingray, and Winchester motherboards, replace "HANA" in all diagnostic steps with "KSB", as HANA functionality was implemented into the KSB. |
- ERROR_NO_ANA/ERROR_NO_HANA
The SMC communicates with the ANA/HANA via the SMBus. If communication is lost, the SMC enters EC_FATAL and the 0010 code is displayed on the front panel.
ANA/HANA Power
- ANA/HANA is powered by V_1P8STBY and V_3P3STBY
- Check that both rails are present at the ANA/HANA
Clocks
- Check that ANA_CLK_OE is high (skip this step for KSB)
- If missing, check pulldown and series resistor
- If still missing, replace Southbridge
- Check that ANA/HANA clock is present
- If missing:
- Xenon: Check Backup Clock Generator and ANA_XTAL_IN series resistor
- Others: Check crystal circuit, replace parts as needed
- If missing:
SMBus
- Check that SMB_CLK and SMB_DATA are not shorted to ground
- If they are, isolate them at the Clock Generator or ANA
- Replace Clock Generator or ANA as needed
- If still shorted, remove Southbridge and recheck
- If short clears, replace Southbridge
- If they are, isolate them at the Clock Generator or ANA
- Check SMB_CLK and SMB_DATA pullups
ANA/HANA and Southbridge
- Replace ANA/HANA
- If error not resolved, replace Southbridge
