HP Recommended

I am experiencing frequent system freezes and crashes on my HP Laptop 15-ef2xxx (SKU: 6A2P0UA#ABA).

System details:
- OS: Windows 11 Home (Build 26200)
- Processor: AMD Ryzen 5 5500U
- BIOS: AMI F.38 (March 20, 2026) ? the latest available

The problem:
My laptop freezes randomly and requires a forced reboot. After reviewing Windows Event Viewer, I found the following errors occurring repeatedly:

? ACPI Event ID 13 ? "The embedded controller (EC) did not respond within the specified timeout period." These fire in bursts every 5 seconds.
? Kernel-Power Event ID 41 (Critical) ? unexpected shutdown/crash
? Bugcheck 0x00000133 (DPC Watchdog Violation) ? crash dump saved to C:\WINDOWS\Minidump\060126-11281-01.dmp

What I have already ruled out:
- Battery is at 100% health (40,733 mWh design vs full charge capacity)
- Internal SSD (SK Hynix HFM256GD3JX013N) shows OK status
- BIOS is already on the latest version (F.38)

The EC errors appear to be the root cause of the crashes. Since the BIOS is already up to date and all other hardware checks out, I believe this may be a hardware-level issue with the embedded controller.

Could you please advise on next steps, including whether this is a known issue on this model and whether a repair or replacement is available?
