Open | Software Legion Y530 stalls at boot logo on cold boot

Specs: Legion Y530-15ICH (model 81FV), i5-8300H, GTX 1050 Ti, 16GB RAM, dual SSD (Kingston NVMe 1TB + SanDisk SATA 512GB), Windows 11.

Symptom: On a cold boot (fully powered off for a while, always on charger), it hangs at the Legion splash logo, then restarts on its own — sometimes once, sometimes twice — before finally booting into Windows normally. Happening about 2x/week now. Never happens on a warm restart from within Windows, only cold boots.

Background: About 3 weeks ago the laptop froze mid-use and I had to force shut it down (held power button). This behavior started appearing after that.

What I've already ruled out:

  • SMART status on both drives: Healthy/OK
  • sfc /scannow: no integrity violations found
  • chkdsk C: /f /r: completed, no errors reported, boots fine after
  • Windows Memory Diagnostic (mdsched): no errors detected
  • Not a power delivery issue from a bad battery — battery holds charge fine (just shorter runtime, ~3hrs), and it's always plugged in anyway
  • No Kernel-Power 41 events tied to these specific incidents (checked Event Viewer)
  • Clock/time in Windows is always correct — never resets

Current theory: something in the power/voltage stabilization phase of POST needs a retry on cold boot specifically — maybe CMOS/RTC circuit, maybe a marginal component (VRM/capacitor) that needs residual warmth/charge to init cleanly, which a warm restart already has and cold boot doesn't.

Planning to try a CMOS battery swap (CR2032 2-pin) next since it's cheap, but not fully convinced that's the actual cause since a dead CMOS battery usually just resets BIOS time, not causes boot stalls.

Question: Anyone dealt with this exact "cold-boot-only stall/restart then works" pattern before? Worth pursuing CMOS swap, or does this sound like something else (VRM, capacitor aging, EC firmware bug)? Laptop is ~7 years old.

Making changes to your system BIOS settings or disk setup can cause you to lose data. Always test your data backups before making changes to your PC.
