Fix STATUS_ACPI_INVALID_ARGTYPE 0XC0140008 Error

ACPI called a method with the wrong argument type — usually a bad driver or BIOS corruption. Start with a reboot, then check drivers, then update firmware.

The 30-second fix: Reboot and check for pending updates

Before you do anything else: reboot the machine. I’m serious — ACPI state gets corrupted by bad power transitions. A clean boot reinitializes the firmware interface. If that doesn’t do it, hit Win + I, go to Windows Update, and install any pending updates. Microsoft has shipped ACPI-related fixes in cumulative updates for Windows 10 22H2 and Windows 11 23H2. A single patch can fix the argument type mismatch if it’s a known OS bug.

If the error disappears after reboot, you’re done. If it comes back after sleep or hibernate, move to the next step — your driver stack is the real culprit.

The 5-minute fix: Update or roll back ACPI-related drivers

What’s actually happening here is a driver is calling an ACPI method (like _SB_.PCI0.GFX0._DOD) with the wrong argument type — maybe an integer when the firmware expects a string, or a buffer when it expects a package. This usually comes from one of three drivers:

Chipset driver – Intel or AMD chipset INF updates fix ACPI method tables.
GPU driver – NVIDIA or AMD drivers call ACPI power management methods. A bad driver revision can pass the wrong type.
BIOS driver – Embedded Controller driver (EC). Often misnamed “motherboard driver” in Device Manager.

Open Device Manager (right-click Start → Device Manager). Look for any devices with a yellow warning triangle — that’s a driver that failed to load, possibly because the ACPI method it tried to call threw this error. For each such device:

Right-click → Properties → Driver tab → Roll Back Driver if the option is enabled. Drivers that worked before an update often break ACPI calls.
If Roll Back is grayed out, go to the manufacturer’s site and download the latest chipset and GPU drivers directly. Don’t rely on Windows Update for these — it often lags behind.
Reboot after each driver update. Test by resuming from sleep or hibernation twice. The error usually surfaces on the second resume.

Still crashing? Move on to the firmware.

The 15+ minute fix: BIOS/UEFI update and ACPI table dump

If drivers are clean and the error persists, the firmware's ACPI tables themselves are broken. This happens when a BIOS update went wrong, or the motherboard manufacturer shipped a buggy revision. The error 0XC0140008 specifically means the ACPI interpreter found an argument type mismatch in the firmware code — not something Windows can fix with a driver.

Step 1: Check your current BIOS version
Run Win + R, type msinfo32, and look for “BIOS Version/Date”. Write it down (e.g., “F5” on a Gigabyte board).

Step 2: Download and install the latest BIOS
Go to your motherboard or laptop manufacturer’s support page (ASUS, MSI, Dell, Lenovo, etc.). Find the latest BIOS for your exact model. Read the release notes — if they mention “ACPI” or “system stability”, that’s your fix. Flash the BIOS following the manufacturer’s method (usually a USB stick with the file). Don’t interrupt the flash — bricked boards don’t boot.

Step 3: If the BIOS is already the latest, dump and analyze ACPI tables (advanced users only)
You can use ACPICA tools to disassemble the tables. Run as admin:

asl.exe -table

This dumps the raw ACPI tables. Look for DSDT.aml and SSDT*.aml. Then disassemble:

iasl.exe -d DSDT.aml

Search for methods that call Arg0 or Arg1 with a type mismatch — the ACPI spec defines argument types as integers (0x00 for Integer, 0x01 for String, etc.). Any method that expects a buffer but receives an integer will throw 0XC0140008. If you find one, you can patch it with a hex editor and override the table — but that’s a per-system fix and requires understanding ASL. Most people should just RMA the motherboard if the latest BIOS doesn’t fix it.

Step 4: Disable fast startup as a last resort
Fast Startup uses a hybrid shutdown that saves ACPI state. A corrupt state can trigger the error. Go to Control Panel → Power Options → Choose what the power buttons do → Change settings that are currently unavailable → uncheck “Turn on fast startup”. Reboot. This is a band-aid, not a fix — if it works, your firmware or driver has a real bug that needs the steps above.

Why step 3 works when nothing else does: The ACPI interpreter in Windows doesn’t guess — it checks every argument type against the method definition. When a firmware method says “expects a buffer” and the caller passes an integer, you get 0XC0140008. Updating the BIOS rewrites the method definitions, so the types match. Disassembling lets you see the mismatch yourself.

If you’ve done all this and the error still appears on every resume, the motherboard may have a hardware fault in the ACPI controller. That’s rare, but it happens — especially on laptops with soldered BIOS chips that develop read errors. In that case, RMA or replace the board.
