Windows XP Won’t Hibernate/Stand By? Disable JQS.exe

Notes: This issue seems to be particular to XP and not Vista or 7. In addition, it is not guaranteed to work as they may be other apps interrupting your Hibernate/Stand By process – but – there’s a good chance it will work.

Java, the thing we all love to hate, is in many cases a necessary evil for specific web sites and apps like the OpenOffice Suite.

For as long as I can remember Java being in existence, people have absolutely hated the jusched.exe (Java Update Scheduler) every single time Java is installed or updated. It’s almost as annoying as when QuickTime puts the qttask.exe (QuickTime Task Tray) on install of its software.

Well, now there’s a new kid on the block from Java, JQS.exe, that being the Java Quick Starter. If you have a recent version of Java installed in your XP, you will see this running in the process list via the Task Manager.

Does anybody want this? No.

Will it block your Windows XP from hibernating/standing by after the time you specify? Absolutely. If you search with Google for common issues as to why XP won’t hibernate/stand by, JQS.exe is usually at the top of the list.

Can you disable it? Yes, but wow is it buried.

1. Go to Control Panel and double-click the "Java" icon.

2. Click the "Advanced" tab.

3. Expand "Miscellaneous"

4. Uncheck "Java Quick Starter"

It looks like this:

Why does disabling this junk have to be so buried? Why can’t this simply be one of the first things you see when you double-click "Java" in the Control Panel? I guess we’ll never know.

JQS.exe will be shut down after you uncheck that box, and chances are if your Windows XP absolutely would not hibernate or stand by after the time you set, it should now work.

    Unfortunately, turning off “jqs.exe” in the Java control panel only turns it off temporarily. After a few days, something turns that checkbox back on in the control panel, and “jqs.exe” starts running again, doing I/O and hogging memory.

    Any idea what could turn that checkbox back on?

  2. Thank you so much, this is exactly what was preventing windows xp from standby/hibernating.
