Siemens Syngo: console hangs when a scan is started
What happened
After the external chiller overheated and its breaker tripped, the syngo console froze every time an attempt was made to start scanning.
What was checked
- The engineers checked the workstation's auto power-on settings after the power interruption, as described in the case.
- They found that date, time and boot path had been lost — typical signs of a dead CMOS battery on the motherboard.
Cause
A dead CMOS battery let the workstation's stored settings (date/time, boot path) reset after the power loss, so the console could not boot cleanly and hung at scan start.
What was done
The engineers replaced the CMOS battery, restored the date/time and re-entered the boot path in the workstation setup; the video card was replaced with an identical model as a precaution, as reported in the case. The problem was solved.
Safety
Unplug the workstation from the mains before opening it to change the battery, and treat a tripped chiller breaker on an MRI as a cooling-system fault that must be diagnosed and cleared before the system is returned to scanning.
Lesson: When a console misbehaves after a power event, check the basics first — a dead CMOS battery can wipe startup settings and mimic a much more serious failure.
