Issues about turning on the system
Problem: System does not start.
Check The Following:
•
Steady, long beeps -- This is another POST code that noted a bad power supply. The difference is,
while the “steady, short beeps” code notes that the power supply may be bad, this POST code notes
that is has gone bad. Be sure that power voltage is in a range of DC 12V – DC 19V.
•
Steady, short beeps -- The power supply may be bad, this is a good one. We tested the power supply
to see if it turned things on, but what if it's not turning everything on? Or if the voltages are wrong?
This POST test helps us narrow the cause down to the power supply. A replacement would usually be
necessary.
•
Long continuous beep tone -- Memory failure. This is usually what you hear when one or both of
your Random Access Memory (RAM) sticks goes bad. If there is more than one stick installed, try
taking one out first to see if the computer boots, if it does not, try with the other one. Usually, this
will tell you which stick has gone bad, and you can replace or upgrade accordingly. If there is only one
stick installed, you will need to replace or upgrade to fix the problem.
