Pattern to record: Cold boot loops before POST but may succeed after several attempts.

Record the boot configuration

Record the laptop model, current firmware settings and whether the SSD is detected before changing boot options. Preserve any BitLocker recovery information so a firmware change does not turn a startup fault into a data-access problem. One possible explanation is that saved timing information no longer matches installed memory or current conditions.

Preserve recovery options

Keep stable power and do not interrupt a firmware write. Increased voltage is not a safe substitute for compatibility.

Firmware and hardware checks

1. Record current settings, check hardware detection and compare a known recovery path before updating firmware.
2. Return memory settings to baseline and test supported modules individually.

Recovery and startup checks

If the checks support this cause, clear only the training data or replace incompatible memory after confirmation. Verification should cover cold boot, restart, storage detection, security state, sleep and Windows loading.

For an assessment of your Windows laptop, contact AEPC in Burswood or call 027 908 8880. Provide the model and the conditions that reproduce this problem. Workshop visits are by appointment.
