    Hi there.
    Many laptops do this because of power saving mode in the bios, what procedure are you using to turn the brightness up?

You can change the brightness from the power saving settings in the control panel.
if the dedicated keys don't work you probably need to install the drivers for the keyboard/multimedia keys, download them from the sony website.

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.

Acer aspire 3000 display dim can i make it brighter?


You should be able to adjust the screen brightness using the "FN" key and the keys that have a sun on them with a arrow up and down. Or you can right click on the desktop and change the screen's brightness in the display properties. And sometimes laptops are set up to automatically lower the brightness when the power properties are set to power saver...like when running on batteries only and no ac power connected.

HP dv1000 monitor just stopped working.


Description During the startup or boot process of the notebook, the display is very dim and barely readable. It remains dim when it reaches the Windows desktop. Restart the notebook with AC power Perform the following steps to determine if the dim display is due to a hardware failure:
  1. Connect the AC adapter to the notebook and a working electrical outlet.
  2. Power down the notebook PC by pressing and holding the Power button for 5 seconds.
  3. Press the Power button again to start the computer.
If the display is still dim after restarting with the AC adapter connected try changing the LCD brightness. Change the LCD brightness From the Windows desktop, hold the Fn key and press the F7 and F8 keys to increase or decrease the brightness of the display. If using the function keys does not resolve the problem, determine whether the Lid Actuator switch is stuck. NOTE: The key number may vary depending on the notebook PC. The image on the key should resemble the following images: Figure 1: Brightness Level Down c00776225.jpg Figure 2: Brightness Level Up c00776226.jpg NOTE: During battery power operation, the notebook display will dim to reserve battery power. Adjust brightness control using the control panel Some notebook PCs have the ability to adjust the brightness through video drivers. If the notebook PC has video drivers with this capability, perform the following steps:
  1. Click Start , Control Panel and then double click Display .
  2. Select the Settings tab and click Advanced .
  3. If the feature is available, a tab with the video card name will be present. If it is, select that tab.
  4. Adjust the desired brightness.
Finding the Lid Actuator switch The Lid Actuator switch is a small button or switch located above the keyboard and LEDs on the right or left side of the notebook. It may also be located near the display hinges. Pressing this switch when the computer is on may turn the notebook display off or cause the notebook to enter a different power state. Press the switch 2-3 times while observing the display. If the display is no longer dim the switch may need to be repaired. Contact HP service and support for further assistance.

Monitor brightness


This is normal for almost every laptop - it is to conserve battery power. However, if you want to adjust the brightness anyway, you can do so by holding down the "Fn" key, and then hitting the number key that has the blue 'brighter sun' making on it. This is usually the F8 key, with the F7 key being the less bright key.
