I get this message, "suspended-computer in use",even when the computer is idle with nothing running. Anyone know what is wrong?

Please post the contents of your global_prefs.xml file and if it exists, the global_prefs_override.xml file. These can be found in your BOINC Data directory, whose default places are in this BOINC FAQ. The directory is hidden.

Once was enough. ;-)
Mind telling me which BOINC version you use?
Are you sure you don't use local (advanced) preferences, stored in the global_prefs_override.xml file?

And is Superlinktechion the only project that you run? I ask as they don't have any work, they seem to have died a silent death back in 2010.

I am using Boinc 7.0.28 and running SETI , Cosmology, Einstien and Rosetta.

Also not using local(advanced)preferences

OK, can you please update your preferences from Einstein@Home and try again? I suspect it's something missing in the (old) Superlink preferences that gets 'activated' in BOINC 7.0

To do so, first edit your Einstein computing preferences. To make sure it isn't the preference I think that's interfering, set the value for "Suspend work if CPU usage is above X%" to 0% or 100% and check that "Suspend work if no mouse/keyboard activity in last X minutes" is set to zero (showing as ---).

Save the preferences with the Update preferences button at the bottom of the page. Next open BOINC Manager, advanced view, Projects tab, select Einstein@Home and click Update. When you now check the Event Log (CTRL+SHIFT+E), you should see that your preferences have been set to those of Einstein.

If it doesn't reflect that, check that you set the preferences for the correct venue (default, home, work, school) for what your computer should use at Einstein and set those accordingly as above.
