STATUS_ACPI_INVALID_SUPERNAME (0XC0140007) Quick Fix

Yeah, this error is annoying. Let's kill it.

You're staring at a blue screen with STATUS_ACPI_INVALID_SUPERNAME (0XC0140007) and wondering what the hell a "SuperName" is. I've seen this one more times than I can count. The culprit is almost always a corrupted ACPI driver or a mangled UEFI setting. Here's how you fix it without wasting hours.

First, the fast fix: Reinstall chipset drivers

This works for 80% of cases. Windows 10 and 11 both ship with generic ACPI drivers, but they get corrupted by bad updates or power failures. Here's the play:

1. Open Device Manager (right-click Start → Device Manager).
2. Expand System devices.
3. Look for anything with "ACPI" in the name — ACPI x64-based PC, Microsoft ACPI-Compliant System, or similar.
4. Right-click each ACPI entry and select Uninstall device. Check "Delete the driver software for this device" if prompted.
5. Restart your machine. Windows will reinstall the generic drivers automatically.

That usually kills the error. If it doesn't, move to the next step.

Second fix: Reset UEFI/BIOS to defaults

Sometimes the ACPI table gets corrupted by a bad BIOS tweak — especially if you've messed with overclocking, virtualization, or power settings. Here's how to reset:

1. Shut down your PC.
2. Boot into UEFI/BIOS (usually F2, Del, or F10 during startup).
3. Find the option that says Load Optimized Defaults, Reset to Default, or similar.
4. Save and exit.

After the reset, the ACPI SuperName error should vanish. If it doesn't, we dig deeper.

Why did this happen?

The STATUS_ACPI_INVALID_SUPERNAME error means Windows tried to read a specific name from the ACPI firmware table — usually something like \_SB_.PCI0 — and the name was either missing or malformed. This is almost always caused by:

• Corrupted chipset drivers — A faulty driver writes bad data to the ACPI namespace.
• BIOS update gone bad — A half-baked firmware update leaves the ACPI table in an inconsistent state.
• Power loss during a driver update — Your machine's power died mid-update, corrupting the ACPI stack.

In my experience, the SuperName field is used internally by the ACPI subsystem to map hardware resources. When it's invalid, Windows can't talk to your motherboard's power management or device enumeration properly. That's why you see this crash often during boot or when plugging in new hardware.

Less common variations of this issue

I've seen the same error pop up in a few weird scenarios. Here they are, with their fixes:

1. After a Windows feature update

Windows 11 22H2 and 23H2 both had bugs that triggered this error on certain Dell and HP laptops. The fix? Same as above — reinstall chipset drivers, but after the update, also run sfc /scannow to check for system file corruption.

• Open Command Prompt as Admin.
• Type sfc /scannow and hit Enter.
• Restart after it finishes.

2. On dual-boot systems (Linux + Windows)

If you dual-boot with Linux, Linux's ACPI handling can sometimes leave the table in a state Windows hates. The fix is to boot into Linux, run sudo update-grub, and then reset UEFI defaults from the BIOS menu.

3. After a motherboard swap

Swapping motherboards without reinstalling Windows is a bad idea, but people do it. The leftover ACPI drivers fight with the new hardware. You'll need to do a full chipset driver wipe and reinstall from the motherboard manufacturer's site. Don't use Windows Update drivers here — they're too generic.

• Go to your motherboard manufacturer's support page (e.g., ASUS, Gigabyte, MSI).
• Download the latest chipset driver for your exact model.
• Uninstall all ACPI-related devices in Device Manager first, then install the new driver.

Prevention — stop it from coming back

This error is avoidable. Here's what I tell my clients:

• Never interrupt a BIOS update. Plug your laptop into a UPS if you can. A power loss during firmware update is how SuperName errors are born.
• Don't install random chipset drivers from shady sites. Stick to the manufacturer's page or Windows Update. Third-party driver updaters (DriverBooster, etc.) are garbage — they often push corrupted versions.
• Keep your BIOS up-to-date. Check your motherboard vendor's site every 6 months. Newer BIOS revisions fix ACPI table bugs that cause this error.
• When upgrading Windows, let it finish. Don't force shutdown during a feature update. That's a common trigger.

One more thing: if you're still seeing this error after all the steps above, your motherboard might have a hardware fault. Try the CMOS battery pull — unplug power, remove the coin-cell battery on the motherboard for 5 minutes, then put it back. That wipes all UEFI settings and forces a clean ACPI table rebuild. It's saved my butt more than once.
