Kristina’s Status Report for 11/15/2025

Hardware Updates & Repairs 

• Replaced previous PSU with a higher-wattage supply to start full-load heater tests
• Fixed issue where screw heads completely de-threaded
  • Used pliers to remove and mount new PSU
• Verified stable operation of power output with new PSU

Data Collection & Testing

• Began running automated synthetic test patterns, including:
  • Ramp up and ramp down CPU power profiles
  • Step spikes
  • Holds
• Debugged issue where tests suddenly stopped mid-run
• Finished a complete sweep of synthetic data collection
• Collected real CPU power traces using HWiNFO on my laptop to simulate realistic user workloads
  • Imported traces into power traces and successfully began running them on testbed

Schedule & Progress

• On schedule

Next Steps

• Begin processing data
• Start building regression model to predict power output
• Start fault-condition runs to collect fault data for anomaly detection
