Razer Blade 14 I 2023 I Ryzen 9 / RTX 4060 - WHEA, random resets, battery mode crashes in under 30sec, AC-only unstable. suspected power delivery problem

Hi,

I’m experiencing a serious and persistent hardware-level issue with my Razer Blade 14 (2023) and I’m posting here after extensive troubleshooting to see if others have encountered the same failure pattern.

System

• Razer Blade 14 (2023)
• AMD Ryzen 9 7940HS
• NVIDIA RTX 4060
• 16 GB RAM (2× SO-DIMM)
• NVMe SSD
• Windows 11

Problem summary

The laptop suffers from random freezes and immediate resets, often without a visible BSOD.

The issue is strongly dependent on the power source.

Power-related behavior:

•  Battery-only: system always crashes within ~30 seconds
•  AC-only: system can run hours, but still crashes 2–3 times per day
• BIOS / Windows Recovery: stable
• Windows load / startup processes → crash

Errors observed

• WHEA_UNCORRECTABLE_ERROR
• MEMORY_MANAGEMENT
• CRITICAL_PROCESS_DIED
• UNEXPECTED_STORE_EXCEPTION
• Sometimes instant reset without BSOD (Kernel-Power 41)

Crashes usually happen:

      •during Windows boot

      •when startup programs load

      •during CPU/GPU load spikes

What I have already tested (extensively)

RAM

• Tested each RAM module individually
• Tested each RAM slot
• No errors → RAM and slots ruled out

SSD

• SMART clean (CrystalDiskInfo)
• Issue persists regardless of disk activity

Battery / Power

• Tested with:
  • original battery
  • brand new battery
  • battery removed (AC only)
• Battery is not the root cause, but battery-only mode exposes the issue immediately

BIOS

• Reset to defaults
• No overclocking / undervolting
• BIOS is stable indefinitely

OS / Drivers

• Clean Windows reinstall
• Multiple driver versions
• Issue persists → software ruled out

Voltage measurements

• Measured with multimeter:
  • DC input ~14–15 V
  • 5 V rail
  • 3.3 V rail
• Voltages remain stable even immediately before reset
  (suggesting transient / timing issue rather than steady-state voltage drop)

Behavior analysis

• Stable in BIOS / Recovery (low load)
• Crashes only under real OS power management
• Battery mode crashes almost instantly
• AC-only mode is more tolerant but still unstable

This probably points to a power delivery / power sequencing issue:

• CPU VRM / SoC VRM
• power controller / PMIC
• or possible CPU/SoC BGA degradation

This does not behave like:

• a driver issue
• a RAM issue
• a storage issue
• a simple battery fault

My conclusion

This appears to be a hardware-level power delivery failure that manifests under dynamic load and power-state transitions.

I am planning board-level diagnostics with a repair service, but before that I would like to know:

Questions

1. Has anyone seen similar failures on Blade 14 (2023) Ryzen models?
2. Are there known issues with power delivery / VRM / SoC rails on this generation?
3. Has Razer acknowledged similar WHEA / battery-mode instability cases?

Any insight from Razer staff or other Blade 14 owners would be greatly appreciated.

Thanks
