IIc on Forever?

[neiderma@eden.rutgers.edu (Kid)]

I finally figured out a use for my spare Apple IIc with LCD panel:
A phone directory.  I always kept my list of phone numbers, 
ftp sites, BBS numbers, in AppleWorks databases.  So I "copied"
them to AppleWorks AWP files, and use a P8 AWP reader to select
which file to run through and scroll around.  Better than using
the stacks of paper I had laying around.  :)

My guru question is how long can a IIc stay plugged in?  Will the
brick burn out if I leave it on for 24 hours?  A week?  A month?
I've heard of Laser 128s being left on to run BBSes but I'm
not sure a IIc is up to it.  Anyone?
