DRIVER_POWER_STATE_FAILURE is the blue screen of the sleep-deprived laptop. It strikes when your Acer tries to sleep, hibernate, shut down, or wake up — a driver doesn’t answer Windows’ power-state request in time, Windows waits, gives up, and crashes to protect the system.

Acer laptops see this one a lot because of the particular mix of MediaTek, Intel, and Realtek Wi-Fi cards Acer ships, plus Acer’s own background utilities that hook into power management. The fix is almost always in the drivers and power settings, not the hardware.

Why this happens

  • Outdated Wi-Fi driver. The single most common trigger on Acer laptops. The wireless driver fails to power down or wake cleanly, especially on MediaTek and older Intel cards.
  • Graphics driver mishandling sleep. NVIDIA or AMD discrete-GPU drivers that don’t transition power states properly crash the system on lid-close or wake.
  • Fast Startup conflicts. Windows’ hybrid shutdown keeps drivers half-loaded between sessions; a driver that can’t handle the resume path crashes on the next boot.
  • Acer bloatware interfering with power management. Acer Care Center, Acer Quick Access, and Acer Power Management utilities sometimes fight Windows’ own power controls.
  • USB devices refusing to sleep. An external drive, dock, or even a mouse receiver that won’t enter selective suspend can hold up the whole power transition.
  • Corrupted hibernation file. A damaged hiberfil.sys breaks the hibernate/resume cycle and surfaces as a power-state crash.
  • BIOS power-management bugs. Older Acer BIOS versions occasionally mishandle modern standby transitions on newer Windows builds.

How to fix it

Work through these in order. The early fixes resolve the vast majority of cases on Acer machines.

Fix 1: Disable Fast Startup

This is the highest-yield single change for this stop code.

  1. Open Control Panel > Hardware and Sound > Power Options.
  2. Click Choose what the power buttons do in the left sidebar.
  3. Click Change settings that are currently unavailable.
  4. Uncheck Turn on fast startup (recommended) and click Save changes.
  5. Shut down fully (not restart) and power back on. Fast Startup’s hybrid shutdown is a notorious trigger for power-state crashes.

Fix 2: Update the Wi-Fi driver from Acer’s site

Don’t trust the generic Windows driver here — get Acer’s build for your exact model.

  1. Find your exact model number (it’s on the sticker under the laptop, or run wmic csproduct get name in Command Prompt).
  2. Go to Acer’s official support site and open the driver download page for your exact model, then download the latest Wireless LAN driver. (Use Acer’s official driver portal only; avoid third-party driver sites entirely.)
  3. In Device Manager, expand Network adapters, right-click your Wi-Fi adapter, and choose Uninstall device. Check Attempt to remove the driver for this device if offered.
  4. Install the driver you downloaded from Acer and restart. A clean reinstall beats an in-place update for this error.

Fix 3: Update the graphics driver cleanly

GPU drivers are the second-biggest offender.

  1. Download the latest driver for your GPU from NVIDIA’s driver page or AMD’s driver page , or Intel’s DSA tool at Intel driver support .
  2. During NVIDIA installation choose Custom and check Perform a clean installation. For AMD, use the Factory Reset option.
  3. Restart and test sleep/wake cycles a few times. If crashes stop, the old GPU driver was the culprit.

Fix 4: Remove or update Acer utilities

Acer’s bundled software hooks into power management in ways that can conflict with Windows.

  1. Open Settings > Apps > Installed apps.
  2. Look for Acer Care Center, Acer Quick Access, Acer Configuration Manager, or Acer Power Management.
  3. Uninstall them one at a time, restarting and testing sleep between each. Keep whichever ones you actually use only if the crashes don’t return.
  4. If you like Acer Care Center’s driver-update feature, update through it once, then uninstall it — you don’t need it running resident.

Fix 5: Stop USB devices from blocking sleep

A stubborn USB device can hold the entire power transition hostage.

  1. Open Device Manager and expand Universal Serial Bus controllers.
  2. For each USB Root Hub, open Properties > Power Management and check Allow the computer to turn off this device to save power.
  3. Unplug docks, external drives, and USB hubs, then test sleep/wake. Reconnect devices one at a time to identify the troublemaker.
  4. As a diagnostic step, go to Control Panel > Power Options > Change plan settings > Change advanced power settings, expand USB settings > USB selective suspend setting, and set it to Enabled for both battery and plugged-in.

Fix 6: Rebuild the hibernation file

If crashes happen around hibernate specifically, the hibernation file itself may be corrupt.

  1. Open Terminal (Admin) from Win + X.
  2. Run powercfg /hibernate off. This deletes hiberfil.sys.
  3. Restart the laptop.
  4. Run powercfg /hibernate on to rebuild the file cleanly.
  5. Test a full hibernate cycle: Start > Power > Hibernate, then wake the machine.

Fix 7: Change the power plan and sleep settings

Aggressive power saving on the wrong components triggers driver timeouts.

  1. Go to Control Panel > Power Options and select the Balanced plan (not Power saver, not a custom Acer plan).
  2. Click Change plan settings > Change advanced power settings.
  3. Expand PCI Express > Link State Power Management and set it to Moderate power savings instead of Maximum.
  4. Expand Sleep > Allow hybrid sleep and set it to Off — hybrid sleep is a frequent trigger for this exact BSOD.
  5. Apply, then test several sleep/wake cycles.

Fix 8: Update the BIOS

If nothing else works, the BIOS power-management tables may be at fault.

  1. Check your current BIOS version with msinfo32 under BIOS Version/Date.
  2. Download the latest BIOS for your exact Acer model from Acer’s official support page.
  3. Follow Acer’s flashing instructions precisely — keep the charger plugged in and don’t touch anything during the flash.
  4. After the update, load BIOS defaults, then re-test sleep behavior before changing any other settings.

Still crashing after all eight? Check Event Viewer > Windows Logs > System for the driver named in the crash — the faulting module is often listed right before the bugcheck entry. This error shares DNA with other power-related crashes, so our general driver power state failure guide and the ASUS-specific variant cover adjacent cases, and if sleep itself is the broader problem, see our walkthrough of Windows 11 stuck on the restarting screen .

Closing

Driver Power State Failure on an Acer almost always comes down to a Wi-Fi or GPU driver arguing with Windows about sleep — with Fast Startup pouring fuel on the fire. Disable Fast Startup, reinstall those two drivers from clean sources, tidy up Acer’s utilities, and your laptop should sleep and wake like it’s supposed to.

Frequently asked questions

What causes Driver Power State Failure on Acer laptops?
A driver fails to respond to a power-state change — usually sleep, hibernate, or shutdown — within the time Windows allows. On Acer laptops the usual suspects are the Wi-Fi driver, the graphics driver, and Acer’s own utilities like Acer Care Center or Quick Access. Outdated drivers and the Fast Startup feature are the two most common triggers.
Why does it only crash when my Acer goes to sleep or wakes up?
Because that is exactly when the bug fires. The error means a driver didn’t handle a sleep or wake transition properly. If your crashes cluster around closing the lid, pressing the power button, or waking the machine, focus on power-related fixes: disable Fast Startup, update the Wi-Fi and GPU drivers, and check sleep settings.
Is Driver Power State Failure a hardware problem?
Rarely. It is almost always a driver or power-management configuration issue. Genuine hardware causes are uncommon — an exception is a failing Wi-Fi card that stops responding to power commands. Try every software fix first; only suspect hardware if crashes survive a clean driver reinstall.
Can I just disable sleep to avoid the crash?
You can, but it treats the symptom, not the cause, and your battery will drain much faster. Use it as a temporary workaround while you update drivers, not as the permanent fix. The real solution is finding the driver that mishandles the power transition.
