    My brother had the same problem with his hp. He had to have it shipped out to the hp repair facilities after notifying them, and then they repaired it. I also have a hp laptop and have not have had any issues with it yet. If your unable to afford such repairs try asking a local computer repair shop for advice.

When you boot it up after you see the main screen, I know that you can barely see but you can see something, on your keyboard there's a key that have 2 screens like this: [_]/[_], it could be by F7 or on it, well you would have to hold down the Fn ( function ) button then press on that key and it will switch from the LCD display from your laptop to a monitor from a desktop, which is the connection you have on the back of your laptop.

Have a Pavilion Desktop HP with upgrade from vista to windows 7 ultimate. Turned the power on and no blue light and no monitor yet the fans were running. Computer monitor said no input and went back to...


Your computer has served you bravely and is now wounded in battle.

arfoob43 either your power supply has died or you computer mainboard is toast.

See my published guide dealing with this matter it is entitled My Computer is not turning on!!! Is it dead!!! No POST!!!

To actually fix it requires a bit of electronics skill. First you will have to diagnose the component that has failed and then solder in the replacement component.

Take care

Power supplies tend to be either working or not working. I would start with the computers memory, reseating the memory cards (there are plenty of tutorials on the web for how to do this). If the power supply fan was running, chances are you did not need to buy a new one. Does it do the same thing with the new power supply?

I have a hp laptop. was on line and screen went black. and will not show again. it strats up sounds but black screen.what do i do


1) Do you have a VGA monitor that you can use for an external monitor?
{VGA monitor is also referred to as a CRT monitor. Looks like a small TV}

The back of the laptop, or side, has a VGA port. The VGA monitor is plugged into it.
{Laptop off}
Then the VGA monitor is turned on, and allowed to 'come to life'.

Now turn on the laptop. Press the Fn key down on the keyboard, and hold it down.
Now press the Monitor toggle over key.
Since you did not state the HP laptop Model Name, and Model Number, I can only give you generic guidance on this.

The monitor toggle over key has a monitor screen symbol on it. It will be one of the F keys.

(It's an External Monitor toggle key.
Press it one time and the display toggles over to an external monitor.
Press it again, and both the laptop LCD screen, and the external monitor have a display on them.
Press it once more, and the display goes back to the laptop's LCD screen )

If display shows up on the external monitor, you have a problem with the display of the laptop.

Primer:
An LCD screen cannot produce enough light by itself. It needs an additional light source.
A Backlight is used as an additional light source.

A Backlight is a CCFL.
Cold Cathode Fluorescent Lamp {Bulb}
Similar to the fluorescent lighting used in homes and businesses, but on a MUCH smaller scale.

{Average Backlight is 3 to 5 inches long, and half the diameter of a No.2 pencil.
The Backlight is located on one edge of the LCD screen}

An Inverter is used to provide power for the LCD screen, and the Backlight.

90 percent of the time the problem is the Inverter.

Inverters are relatively cheap, and if I knew the Model Name, and Model Number of your HP laptop, I could give you a link to HP Support where you could download the Service Manual for free.

This way you would have a manual to show, and detail how to replace the Inverter, and I could guide you.

I could also give links for your perusal for Inverters.

There is one more thing however.

HP Pavilion DV2000, DV6000, and DV9000 series laptops, have a graphics chip overheating problem.
The laptop comes on, the blue indicator LED lights light up, but the LCD screen is black.

This video explains why, shows a solution to fixing the problem, and details out a lot more than I am privileged to state here,

Is nvivia gforce 7300 compatible with a6010n hp motherboard


if your PC has a built in graphics adapter then the bios and windows will automatically use that as a primary display unit..u need to boot the PC with that and then check in the device manager if the PC has picked up on the new display unit.. if it has then disable the on board one. the pc will ask to restart ... do it.. then when it does connect the monitor cable to the new display device.. and make sure that the monitor has an image of the start up screen if it does then you have completed the upgrade
