    Turned out my laptop was still under warranty. Called HP, they Fed Ex'd me a box with shipping label, got my computer back in 3 days, start to finish, although they told me it might take up to 2 weeks. They had to put in a new screen. Their customer service was fantastic, and the laptop is working perfectly.

Definatley the display close power switch, located under switch/speaker panel.im not sure if the hinge activates it or not. looked into mine and found part# tag interfering w/ power switch board, cleaned it up, working good now. discovered this by gently pulling top left and pushing lower right of display, it would flicker.thaught it was closed probably a result of closing it with right side after every shut down.im trying to close only from middle..i also try never to pick it up from one corner, plastic is very bendy and screw comes loose.two hands always, specialy where rom is.i think your monitor thinks its closed. while black hold it under bright light and you can see enough to navigate.tried svid, used it for safemode driver check, took several hours before i got to hinge. i hope this is your troubles as they cost nothing to repair.my warrenty left 22 days ago.i was sweating.hope this helps.

I have a compaq presario cq 60 to and when I turn it on it just sounds like it's going to start up and goes to a blank bluish black screen if I did it says the main screen and then it goes to that after I...


The blue screen typically would have a error message on it. I would recommend hitting the F8 key once a second after turning the computer on to get the windows diagnostic menu with choices such as safe mode. If you can select this then try a system restore point to when the computer was working properly. If you are unable to have it start up by hitting the F8 key then you either have a failing hard drive or a corrupt windows.

How do I enable a compaq laptop's keys


Compaq Presario computers provide users with a row of function keys for added keyboard functionality. Function keys can serve a dual purpose as well.
Function keys are located at the top of Compaq Presario keyboards.
By learning how function keys work on a Compaq Presario you can take advantage of time saving keyboard shortcuts.Purpose
Use function keys to access menus, save changes and create shortcut keys.
Various applications, including Microsoft Office, allow you to select a function key as a shortcut key for running specific tasks. These settings are usually found under the Tools, Settings or File menu.
Each Compaq Presario computer has twelve function keys.
The most common used keys are "F2," "F8," "F10" and "F12."
The first three are used mainly to access and use the Compaq BIOS. "F12" is used to access a set of run from options during the boot process.

How to Access
Access function keys on a Compaq Presario by pressing any of the keys on the top row of the keyboard. Access the key's dual purpose by first pressing the "Fn" key located on the bottom row of keys.
Use function keys as shortcut keys by pressing them anytime while in the desired application. Remember, you must set them as shortcut keys first.
Note that some programs may already have certain function keys set as shortcuts.
Open menus and view the shortcut keys beside each menu item before setting your own shortcuts.


Dual Uses Each function key has a dual use. Press "Fn" plus the desired function key for the key's other use.
Below each function number is a small picture within a square or rectangle.
This dictates the dual use. "F1" opens help and support. "F2" serves as a printer shortcut.
Open your homepage by pressing "F3."
If you use dual monitors, switch between monitors by using "F4." "F5" puts your computer in stand-by mode.
Quickly lock your computer by pressing "F6." "F7" and "F8" adjust the screen's contrast.
Play and pause your music in Windows Media Player or other default media player by using "F9."
Press "F10" to stop playing media. Skip ahead or rewind media by using "F11" and "F12."

Other "Fn" Keys

In addition to function keys, the "Fn" key is also provides other keys with a dual use.
Any key with a small square on the key has a dual purpose such as the "scroll," "insert" and "delete" buttons.
Since laptop keyboards have no number pads, certain keys serve as the number pad by pressing the "Fn" key.

Have you checked the brightness options for the screen using the HP function keys? Fn +F7 or Fn+F8 should adjust the brightness of the screen for that C306 model laptop. If adjusting the brightness has no response then try the next steps.

What happens if you turn the computer off, plug it into an external monitor or projector, and then turn the computer back on? If the video displays correctly on a computer monitor or projector, but it stays dim on the LCD screen of the laptop, then the laptop LCD Screen Back-light or inverter is probably going out. You'll need to contact HP for a replacement part or take the laptop to a certified repair center.

Compaq Presario R 4000 to dark when on battery only.


The R4000, or at least mine will appear to be brighter when on battery also. If you press the function key and then the f8 key it will brighten the screen.

Blank (dark) screen


If you can still see a faint image on the screen, then its the inverter coil or the inverter itself which has gone bad or maybe even worked itself loose causing a bad connection.
Either way you will have to take it to PC repair shop to be looked at.

Good luck and thanks for using Fixya!

Compaq Presario R3000 dim screen but not dark


Sounds like the auto-dim in the BIOS is set too low. Fortunately the Compaq R3000 allows you to adjust the brightness right from the keyboard. Hold down the [FN] function key while tapping the [F8] key will brighten the screen, while [FN]-[F7] will dim it. The settings are different for running on AC power and battery, so you must do each individually.
