Hello, I believe this is not a problem, I have encountered similar problem and I have reason to believe this happens when the computer memory is running slow. Please try uninstalling unnecessary software to see if that changes things. I hope this solution has been helpful. Have a wonderful day.

How do I turn down brightness on my hp Windows 7 computer?


Hi,

Below are instructions to adjust brightness on HP laptop

    • Press the "Fn" key with the computer turned on and hold the key.

    • Press the "F7" or "F8" key on some HP laptops, which are printed with a small sun icon on the key. The sun icon is filled on the function key for dimming the laptop. The other key is printed with a hollow sun icon for brightening the screen.

    • Press the "Fn" and left arrow keys together on some HP laptops to turn down the brightness. The "Fn" and right arrow key will increase brightness. Press and release the right arrow key repeatedly, while holding down "Fn," to decrease the screen brightness slowly, or hold the keys to darken the screen as low as the setting will go.

  1. For HP Monitors

    • Press and hold the down arrow key on the front panel of the monitor below the screen to turn down the brightness on the external monitor to the lowest setting.


    • Repeatedly press the down arrow button to dim the monitor gradually.


    • Press the up arrow key on the monitor to increase brightness.


Regards,
Rahul

Blank screen


Check keyboard for 'F' keys which relate to screen Functions. Look for brightness UP or DOWN keys and if nothing else works hold down POWER button until it shuts down. Then push button and allow it to start up again. It will run through self-diagnostic testing and will ask if you want to run computer in Safe or Other Modes-pick Normal Mode.
Very often this will fix the problem.

Boots up but black screen


If your laptop screen is not working and is blank, you are out of luck as far as working on your computer. However, while there may be a major problem you need to troubleshoot, there are some easy solutions to keep in mind as well, such as brightness settings and your power source.
1.Check the power source. While you have presumably already attempted to turn your laptop on and off, the problem may lie with your AC power adapter. Is the power-indicator light on the adapter on? If not, your problem may lie here. However, whether or not you have a power indicator light on your adapter, consider unplugging it and plugging it into another outlet. This may turn on your laptop and take care of your blank-screen problem.
2.Check your brightness settings. While it seems like a simple oversight, the brightness on your laptop may sometimes be turned all the way down. Thus, the screen appears to be black, off or defective, when the problem is simply that the brightness is on its lowest setting. To fix the brightness, check your laptop keyboard. Most laptops have the brightness settings mapped to two keys at the top left of the keyboard, accompanied by a symbol (often a sun). Use these keys to fix your brightness, but keep in mind that some laptops require that you press the Function key at the same time as the Brightness key.
3.Check the status of your laptop battery itself. There should be a battery indicator on the laptop that is connected to the battery. This indicator is either on the bottom of the laptop or (likely) on the side. If there is no indicator, your battery itself may be the problem, and may require replacing. Keep in mind that older batteries of the nickel-cadmium variety are more likely to decharge over time and forget their initial maximum charge level; this may be a particular issue to users of older laptops.
4.Find a VGA connector and hook up your laptop to an external monitor if the above steps have not alleviated the blank-screen problem. Turn on the computer and the external monitor. Does the external monitor light up? If so, the blank screen is likely due to a video subset problem/LCD problem in your laptop.
5.Consider that a deeper problem may exist if the external monitor did not light up This problem may lie in the motherboard. In this case, taking the laptop to a professional repairman or sending it off to the manufacturer is recommended.

How do i adjust brightness in hp g60


Here's how to adjust the screen brightness for a laptop in Windows 7:
  1. Go to Control Panel -> Hardware and Sound -> Power Options.
  2. Click on "Change plan settings" for your laptop's selected power plan (either Balanced or Power saver).
  3. Now edit your plan settings by moving the sliders next to "Adjust plan brightness" at the bottom. You'll be able to change the brightness for when your laptop is On battery power, or when it's Plugged in.
  4. Once you've adjusting the brightness settings to your liking, then click on the 'Save changes' button.
Alternatively, here is another way: From the Windows desktop, hold the fn key and press the f7 key c00776226.jpg to increase or the f8key c00776225.jpg to decrease the brightness of the display. If using the function keys does not resolve the problem and you have a Lid Actuator on your particular model, check the movement of the Lid Actuator switch to determine that it moves freely and is not stuck. NOTE: The key numbers (f7 or f8 ) may vary depending on the notebook PC; however, the images on the keys should be similiar. If you reboot the PC after using the function keys to change the LCD brightness settings, the brightness may return to the default setting on some models, which is based on the power source-battery or AC. This is not an error. The notebook is functioning as designed. If the notebook returns to the default setting after rebooting on your particular model, use the function keys to change the brightness back to the desired settings.

I have a compaq paserio notebook and when I boot up the computer, either I get a blank screen or I get a very faded image that I can't hardly see so I can't log on. Most of the time I just get a blank...


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.

I need an explanation as to the secondary function of the keys on my NB305. Mainly the top row of 'F' keys, but the remainder of the keyboard as well. What do all these little symbols on the keys mean?


F1 through F12 are called function keys because they execute programmed functions when pressed. Used in combination with the Fn key, keys marked with icons execute specific functions on the computer. The function executed by individual keys depends on the software you are using.





1. Sound Mute: Pressing Fn + ESC in a windows environment turns sound on or off. Press Fn + Enter to simulate Enter or the enhanced keyboard's numeric keypad. 2. Instant security: Press Fn + F1 to blank the screen to prevent others from accessing your data. To restore the screen and original setting, press any key or press the Touch Pad. 3. Power save mode: Pressing Fn + F2 changes the power save mode. 4. Standby: When you press Fn + F3, the computer enters Standby. 5. Hibernation: When you press Fn + F4, the computer enters Hibernation. 6. Display selection: Press Fn + F5 to change the active display device. Hold down Fn and press F5 again to change the device. 7. Internal LCD screen Brightness: Pressing Fn + F6 decreases the display brightness in decrements. 8. Internal LCD screen Brightness: Pressing Fn + F7 increases the display brightness in increments. 9. Wireless setting: If your computer has both Bluetooth and Wireless LAN functions, you can press Fn + F8 to select which type of wireless communication you want to use. 10. Touch Pad: Pressing Fn + F9 in a windows environment enables or disables the Touch Pad function. 11. Press Fn + F10 or Fn + F11 to access the integrated keypad. When activated, the keys with gray markings on the bottom edge become numeric keypad keys (Fn + F11) or cursor control keys (Fn + F10). The power on default for both settings is off. Press Fn + F12 (ScrLock) to lock the cursor on a specific line. The power on default is off. 12. TOSHIBA Zooming Utility (reduce): To reduce the icon size on the desktop or the application window, press the 1 key while holding down the Fn key. (13. TOSHIBA Zooming Utility (enlarge): To enlarge the icon size on the desktop or the application window, press the 2 key while holding down the Fn key.
