Question about Computers & Internet
When i turn on my computer, the lights (green and red) near the power button continues to light up , but the light in my samsung dvd drive does not flash at all. The drive does respond when i push the eject button. I have changed the power cable for the drive no response. the computer does not boot, nothing appear on the screen of my monitor ( no bios, no POST ).
motherboard (ABIT IL8), graphic card (7100 gs nvidia,) hard disk 80 gig , ram 512 mb 533
No bios no post and no power lights on disk drives means hardware problem.
Either call a technician or try the following if you feel you can do it yourself, beware , there is always risk of damaging your PC on DIY.
unplug the computer, open PC and remove all plugs and internal and external devices, leaving only a minimal set of devices.
Start the motherboard with only Power adapter , one RAM module, and video card and screen connected. Unplug all disks and external devices, remove all pci cards.
If it still does not start take it to a repair shop, you may need to replace power supply, motherboard or ram.

you plug in the power cord is there any lights whatsoever on the computer?
When you press the power button do you hear fans running, hard drive spinning, lights on the computer, hear any beeps or lights constantly blinking, hear the DvD/CD drive click and the light on the drawer of the DvD/CD turn on for a second or two? If so the laptop is trying to boot or may have booted, but the screen is not showing for some reason.
Beep tones and blinking lights tells the technicians what is going on with the computer and why it is not booting. Most times it's a motherboard issue when you hear beeps or blinking lights continuous. Most times the problem is with the memory or Video Card. Count the Blinking Lights or Beeps and take note of their pattern (1 Long or 1 Long followed by 2 Short).
Maybe your power cord is bad if you don't get anything to happen whatsoever when you press the power button.
you have a Static Charge Buildup. Remove the Power Cord, then Press and
Hold the power button for 30 seconds. After 30 seconds plug the power
cord back in and hit the power button to see if it boots.
your memory is bad or the memory slot is bad.
the Power Cord, Open the Case and remove one of the memory chips. Set the
chip aside then try rebooting the computer. If it boots, then you know
the memory chip you set aside is bad so mark an x on it with an ink pen.
If it fails to boot then move the chip to the next memory slot and try
rebooting. If it fails take the chip out and set it aside, then put the
other chip in and try booting it in both slots. If it boots, just to
verify that the chip set aside is bad, mark an x on it and put it into the open
memory chip slot and try booting.
your power supply is bad. Sometimes there is enough power to make the
power light or some other lights come on but not enough power to make the fan
turn on or hard drive spin.
Below are links and info I found from Dell's Website based on your model.
Controls and Lights Front of computer:
Power button - push button
green light - Blinking green in sleep state; solid green for power-on state.
amber light - Blinking amber indicates a problem with the power supply inside the computer. If the system cannot boot and there is a solid amber light, this indicates a problem with the system board (see "Power Problems" in your Owner's Manual).
four lights on the front panel (see Diagnostic Lights.)
Standby power light
AUX_PWR_LED on the system board
Hard-drive activity light
green light - When the computer is reading data from or writing data to the hard drive.

My LOEWE CAL 232 will not power up. When the power button is pressed, the monitor turns on, with the LOEWE on the monitor, then the TV continues with the previous activity (antenna, DVD, VCR etc.). Now all that happens is
1. the red light comes on
2.after about 1 second the green light turns on for about 12 seconds
3. the the green light turns off for about 1 second
4. then the green light turns on again for about 12 seconds
and this continues until the power button is pressed to turn the TV off. During this time, the monitor does not turn on and the only sound I hear seems to eminate from the power button.
