Here is another problem. This time my PC seems to have shut down problems with Windows 8.1.
Scenario: My Desktop is relatively new (assembled on Nov 1st 2013) with i7 Haswell Processor, Asus Z87 PRO Motherboard and Win 8.1. I had problems in the beginning with Win 8.1, most of them related to Asus driver issues and software compatibility which is almost completely fixed now. However, there is one issue I ignored. Whenever I shut down my PC, the blue LED on my Power button remains turned on for almost 10-15 secs, somtimes even up to a minute. This happens even after the Monitor goes bank and the fan sound from CPU and Graphics card stops indicating the PC is shut down completely.
Usually I ignore the blinking blue LED light and turn off the SMPS power supply as soon as the fan sound stops and monitor turns off, until the day my OS did an automated scan for checking driver error as soon as I turned on my PC. This happened twice continuously and that is when I decided to take a look into this problem. After some searching online, it is clear that Win 8 and 8.1 do have some issues with shutdown. In this article, let me show you how to fix shut down problems with Win 8 and 8.1.
Check the Event Viewer
- Press Windows Key + R, type eventvwr and click OK. This will open Event Viewer window
- On the left window pane, expand Windows Logs
- Check both Application log and System log
- Check if there are any error logs registered at the time of computer shut down
- Check the details under Error logs. Check what is listed under Faulting Application Name. This might be the software or device driver which is interfering with proper shutting down of computer
- Once you get the name of software, uninstall and re-install the software. (The software might be corrupted or had some settings changed as a result of changes in the PC. Re-installing the updated software should fix the problem.)
In my case, the error messages in event viewer were erratic and didn’t point towards any one software. Even though some error log did coincide with the time I shut down computer, it was not pointing towards any particular application. So I assumed it should be something else.
Check the Hybrid Shutdown feature
Hybrid Shutdown is a feature introduced with Windows 8. Basically, it allows Win 8 to boot 30-70% faster than previous operating systems. It works on the principle of system hibernation. When a shut down is done, the kernel session is hibernated. So when the computer turns on, the kernel session is restored which significantly reduce start up time.
- Press Windows Key + R, type powercfg.cpl. This opens Power options -> System Settings
- Click Choose what the power buttons do
- Click Change settings that are currently unavailable to make changes.
- Under Shutdown settings, disable Hybrid shutdown by unchecking Turn on fast startup
- Restart computer.
In my case, the issue was fixed by turning of Hybrid shutdown feature. The power LED light went off at the same time when monitor and fan stopped spinning. Also I didn’t notice any difference is boot up time. It was faster before and faster now. Note: You might find a slight difference in boot up time after disabling Hybrid shutdown.
Hopefully this should fix the shut down problem in your computer. Use the comments for feedback and if any queries.
