When computer boots the power light on monitor blinks but nothing is displayed

Are you powering on your computer and your monitor...

If your computer appears to boot, but nothing on your monitor...
Here's some tricks I would try. Something here, might help...
1. Verify the monitor's power cord is plugged firmly into the wall outlet and the back of the monitor.
2. Verify the monitor cable is firmly connected to the computer and the monitor.
3. Verify that you have turned the monitor power switch on.
4. If the power light on the monitor is not on, test the wall outlet (plug in a light or something you know works).
5. If the power light on the monitor is not on, try a different power cord.
6. If the power light is on and yellow or orange or flashing, but nothing displays, or the display is incorrect, borrow a monitor from a friend. If that works, your monitor probably needs replaced.
7. Also, you could try your monitor on a friend's computer. If it doesn't work, your monitor probably needs replaced. If it works properly on your friends computer, the problem may be with your computers video output port, motherboard video chip (or video card, if you have one), or drivers.
Good luck.

If your computer won't boot...
The hard drive, motherboard, or some other critical component may be failing, or just the OS or hard drive corrupted. If you have files that you do not want to lose, you could try this... Pull the hard drive out, and use a "USB Hard Drive Adapter" (available fairly cheap online) to connect the hard drive to a friend's computer, and save all the personal files (documents, pictures, etc.) you can to a folder on the friend's computer or an external hard drive. That way, at least you may not lose your files.
Then, you could try to do a Factory Restore or Reload on the computer, and if that works, copy your personal files back to your newly restored computer. Good luck.

Maybe one of your memory chips is bad.

If it seems to boot up all the way except the display is blank try the steps below:

Borrow a monitor from a neighbor, friend, relative or co-worker and connect it to the computer. If the Borrowed monitor display the desktop then the original monitor is bad, but the video card inside the computer is ok. If the Borrowed monitor does not display then the video card inside the computer is bad.

If it does not seem to boot up all the way try the steps below.

When you plug in the power cord is there any lights whatsoever on the laptop, where the plug goes in or on the AC Adapter of the power cord?

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 computer 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 laptop 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 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.

Maybe your memory is bad or the memory slot is bad.

Remove 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.

If it seems like the computer completed the boot process but the screen is blank, try the steps below.

The problem will either be the monitor or the video card inside the computer. Connect another monitor to the computer to isolate the problem. Borrow a monitor from a neighbor, friend, relative or co-worker and connect it to the computer. If the Borrowed monitor displays and works ok, then your original monitor is bad and the video card is good. If the Borrowed monitor does not work then the video card inside the computer is bad.

If the computer did not complete the boot process then try the steps below.

Did it boot all the way? Do you hear the fan running, disk drive spinning? If it sounds like it booted but the display is black, try this:

* check cables
* boot windows in safe mode, perhaps the screen resolution is too high to display on the monitor

Actually it boots, just that you don't see it. Try using another monitor - even a tv will do: disconnect the present monitor, connect the new one and reboot. If you get an image then the monitor is dead, replace it. If you don't then the onboard video card id dead, get a new one and try again. If even now it.s dead then you need a new motherboard.

CHECK THE REFRESH RATE ON TH OLD COMPUTER MONITOR AND MOVE IT TO A HIGHER REFRASH RATE IN THE CONTROL PANAL, MONITOR, PROPERTIES, ADVANCE SETTINGS

Fond one solution I think.

This works if you boot the monitor with a pc, open the osd menu and go to reset. reset the monitor.
