Fix 0x0000030E: System Power State Transition Error on Windows 10/11

1. Fast Startup is corrupting your power state handoff

What's actually happening here is that Fast Startup—a hybrid shutdown feature Microsoft enabled by default since Windows 8—is a common culprit. It keeps kernel and driver state in a hibernation file so your next boot feels snappier. But if that saved state gets stale or a driver misbehaves during the transition, you'll hit 0x0000030E when the system tries to enter or leave sleep or hibernate.

I've seen this trigger reliably on Lenovo ThinkPads and Dell XPS laptops after Windows updates. The fix is simple: disable Fast Startup. It doesn't affect your ability to sleep or hibernate manually.

1. Open Control Panel > Power Options > Choose what the power buttons do.
2. Click Change settings that are currently unavailable (you need admin rights).
3. Uncheck Turn on fast startup (recommended).
4. Click Save changes and restart your PC.

After that, test your sleep/resume cycle. If the error disappears, you're done. If not, move on to the next fix.

2. A driver is failing to handle the power state transition

The second most common cause is a driver—usually for your network adapter, GPU, or chipset—that doesn't support the power state change. The error code itself says it's transitioning from %2 to %3, but Windows doesn't tell you which driver failed. You have to dig.

Open Event Viewer (eventvwr in Run). Go to Windows Logs > System. Filter by source Kernel-Power or Power-Troubleshooter and look for events with ID 1, 42, or 506 around the time of the crash. The details often name the guilty driver.

If you see something like Intel(R) Wi-Fi 6 AX201 or NVIDIA GeForce RTX 3060, update or roll back that specific driver. Use Device Manager to manually install the manufacturer's driver from their site—don't rely on Windows Update alone. For example, Intel wireless drivers between version 22.100.x and 22.150.x had known issues with power state transitions on Windows 11 22H2.

3. Corrupted power policy or hibernation file

If neither of the above works, the issue is a corrupted power policy or a broken hiberfil.sys. This happens when Windows crashes during a previous power transition and leaves the file in an inconsistent state.

Run an elevated Command Prompt (Win + X > Terminal (Admin)) and execute these commands in order:

powercfg -h off
powercfg -h on
powercfg -restoredefaultschemes

First, powercfg -h off deletes and disables hibernation. Then powercfg -h on creates a fresh hiberfil.sys. The -restoredefaultschemes resets all power plans to factory defaults—this wipes any custom timings but guarantees no corruption in the policy.

Restart your machine after these commands. The reason stepping through these three commands matters is simple: -h off forces the OS to tear down the old file, and the subsequent -h on builds a clean one without referencing any stale state.

Quick-reference summary table

I'd start with the powercfg commands if you're short on time—they cover both Fast Startup and policy corruption in one go. But if the error only happens when resuming from sleep, skip to the Fast Startup toggle first. Either way, you'll get this fixed without reinstalling Windows.
