Subj : Flickering Power LED

Hi Folks!

Have a blue power LED which has started to randomly flicker.  Several days
ago I noticed it was occasionally dimming rapidly and randomly; past
couple of days a definite flicker and lst night and this morning it if 
off for random times.  The random flickering reminds me of a HDD 
Activity LED but that one seems to be working normally.

This morning I plugged: a USB voltmeter: usually a 4.94v but 
occasionally briefly dips to 4.93 and rises to 4.95v.  AFAIK that 
variation is normal.  ...LED is finally staying off and the voltmeter 
reading 4.94 volts -- of course I don't know if the PSU output for the 
Power LED and USB port are the same -- probably not.

Suppose I should also mention this is on a computer I built a year or
two ago.  Motherboard is Asus M5A97 R2.0.  No idea what the PSU is but 
would be a decent brand and power capability.

So the question is is this something to be concerned with, as in 
indicating an upcoming failure (and of probably what - power from the 
PSU but the motherboard control this little light).  Unit is headless, 
so I'll probably add a small monitoring LED into a USB port so I can 
tell at a glance if the unit is powered.

TIA!
