I have what seems to be a set of unrelated problems on 2008 hardware
running Wheezy and GNOME. 

The problem started with a loss of both keyboard and mouse inputs. When
I did a hot reboots I found the results to be unpredictable.

Sometimes the power LED comes and then goes off after a second and
starts an unending cycle that resumes if the power cord is detached and
re-attached. 

Sometimes the power LED and the HD LED both on for a few seconds
and then both go off to start the on-off cycle for both. 

For a while the machine could reach GRUB menu, when it rebooted itself. 

Once it actually started X server and allowed user log in. Everything
worked for about 12 hours, and then mouse and keyboard were again lost. 

Right now when I tried to boot DebLive from USB key, the power supply
LED is on without recycling, but no power to HD and boot process is
hung.
 
What connection could there be between the faulty operation of the X
server and errative power? The hardware is from 2008, Could it be that
the BIOS battery needs replacement? The HD is being supplied with 5 and
11 volts in its power connector.
