Question about HP Compaq nc6220 Notebook

1 Answer

No screen activity

There is no activity on the monitor at all. Power up, the computer spins the drive, lights are working, but no screen activity. Not even a motherboard boot screen. Is there a way to fix the computer or does it need to be hacked?

Plug in an external monitor to see if it is booting normally and it is only a screen malfunction.

If you plug in an external monitor and the screen works then it's just a monitor issue.
If the external monitor doesn't light up then try unplugging the power cord, taking out the battery, holding down the power button for a minute and then plugging the AC back in trying to power it up.

If it doesn't power up. Then it's probably a motherboard issue.
I would get an external hard drive enclosure (2.5) and take out the harddrive and plug it into another computer to take the data off.
You can then send in your computer to repair somewhere but for the price, you may as well buy a new one.

I have problems in sarting up my EI System laptop ,the power light is on but no display on screen


The power light will only show whether power is reaching the machine. The important light is the hard drive activity light and perhaps the wireless activity light.

If the power light is all you have you should take your laptop to the computer doctor but if the hard drive light shows activity it would be worth connecting it to a separate monitor and if it then produces a display you might be able to figure out what has happened.

EMachines eMD620 suddenly shutdown and not boot anymore


When this happened was the laptop overly hot? If the laptop's head got too high it could have shutdown to protect itself. It wouldn't boot until the heat had disparate. Sit you laptop aside for about 30 minutes and see if it will boot then. If it does you might want to check out a cool mat.

Computer won't boot up


Does it sound like the computer booted up except the screen is black. Do you hear fans running, the hard drive spinning? Maybe the system booted up, but the screen has an issue.

Shine a flashlight on the dark screen to see if you barely see the icons on the desktop. If so, then the LCD Inverter is bad.

Plug in an external monitor and see if the display shows up on it. It can be any kind of monitor even the old big fat crt monitors as long as it has a vga cable to connect to your computer's vga port. If so that proves your video card is ok. The video will show on most systems when you reboot without you having to do anything. Some systems will require you to hit the FN (Function key) + F1 thru F12. Hold down the FN key then hit the correct key for displaying on the monitor (F1 thru F12). The correct key will normally have CRT/LCD on it or it will have the icon of a display.

If you see no icons by shinning a flash light and the external monitor works, then your screen is bad. If you see no icons by shinning the flash light and nothing shows on the external monitor, then most likely your video card is bad.

TVonics DTR HV250-Just the fan can be heard nothing else.Screen does not light up.Anybody know how i can fix it?Thank you


test all leads that attach to your hard drive including electrical extensions

the leads from your ((motherboard to your hard drive)) Sata make sure they have dust free secure connection and are not faulty or just replace them they could be faulty

make sure all leads that are attached to your drives dvd\cd have secure connections and are not faulty or just replace them they could be faulty ?


even something as small as an electrical extension or a faulty fan lead can cause this problem follow the troubleshooting procedure a computer needs all of the data and electrical current to travel through every working device and to have an end for a computer to be able work properly

make sure your graphics card is securely seated with no dust


if you remove the graphics card to clean the socket replace it

restart the computer the found new hardware wizard should activate

Blank screen


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:
When you press the power button do you hear fansrunning, hard drive spinning, lights on the computer, hear any beeps or lightsconstantly blinking, hear the DvD/CD drive click and the light on the drawer ofthe DvD/CD turn on for a second or two? If so the laptop is trying toboot 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 thelaptop and why it is not booting. Most times it's a motherboard issuewhen you hear beeps or blinking lights continuous.

What stops computer from starting up


hi

turn off the notebook. take a regualr desktop monitor VGA or LCD monitor and plug into the notebook (make sure to power up both the notebook with AC adapter and power cord for monitor). Turn both on and you should see video on the desktop monitor . if you do not see anything, i would hint at the fact that the notebook screen may be bad. Do you hear the hard disk drive spinning when you turn on the notebook ? if so, thats a good indication that the mainboard is still working and that the LCD screen on the notebook is not functioing . You will have to replace the LCD (notebook) screen

IBM Thinkpad 701CS monitor lights up but no picture


Looks like your hard drive is having a problem, and if it spins then the cable from the motherboard to the tft screen is faulty. You will need to open up the casinf to replace the cable or re-attach it if it has loosened somehow.

Dead compaq laptop, no boot activity


Larnold..Sounding like you need to check the LCD Power Inverter Circuit board.. this is located inside the screen a long rectangular circuit board that sends power to the screen backlight & Display Panel.. Could also be a Bad Backlight.. Try Booting it.. Hold it up to a light and look closely at the screen.. If you see a faint image but no light, it is the Backlight, if Just Black No Activity then its most likely the Power Inverter, OR a Bad Video Card.. You can test the VIDEO by Connecting the laptop to a Computer Monitor or similar with the laptops VGA Serial port.. then Use your function Key and Switch to 2nd Display.....(one of your F keys.. ).. If it Shows up on another screen, Its a Display problem and not the video card... Hope This Helps alittle.. Cheers
