To fix various driver issues on your PC, you will need a dedicated tool to find the freshest and the original drivers. You can use PC HelpSoft Driver Updater to do it in 3 easy steps:
TheERROR_SET_POWER_STATE_VETOEDsystem error, with code1140 (0x474), appears when an application or driver prevents Windows from changing its power state, i.e., sleep, hibernate, or shutdown.
The error message reads,An attempt to change the system power state was vetoed by another application or driver, but it doesn’t tell us anything about the app or driver that caused the error in the first place. So, troubleshooting may take some time!
Before you proceed, restart the PC, disconnect all non-critical peripherals, and install any pending Windows updates. For many of you, these quick checks alone should fix the error!
How can I fix ERROR_SET_POWER_STATE_VETOED?
1. Terminate active applications
2. Uninstall conflicting apps
If the problem persists after a quick removal, the app may still have some leftover files triggering the1140 (0x474)error. In this case, I recommend using atop-rated software uninstaller for Windowsto get rid of any remnant app cache or Registry entries.
3. Reinstall the malfunctioning driver
4. Update the affected driver
If you were able to find the conflicting one in Windows error logs, simplyupdate that driverinstead of all the installed ones. In case Windows tells you that the best driver is already installed, head to the manufacturer’s website, find out the newest version, and thenmanually install the latest driver!
5. Repair the corrupt system files
In a few cases, theERROR_SET_POWER_STATE_VETOEDWindows system error was caused bycorrupted system files. Here, simply running the SFC(System File Checker)andDISM(Deployment Image Servicing and Management)scans should replace the protected system files with their cached copy.
6. Disable fast startup
7. Perform a system restore
A system restore allows you to revert the PC to a previous stable state where theERROR_SET_POWER_STATE_VETOEDissue didn’t exist. All you need is arestore pointcreated before the issue first appeared!
In case a restore point is not available, the last option is toreinstall Windows. For that, get theWindows ISOfromMicrosoft’s official websiteand then proceed with the reinstallation.
