Windows 7 Backlight level too bright

[veer26]

Hi,

I'm using a Fujitsu S6520 that I recently upgraded to Windows 7 Professional (32 bit). The fujitsu comes with 8 preset screen backlight levels that can be adjusted via the fn key on the keyboard. Prior to this, I was using Windows XP on the same computer, and I used to set the backlight at level 3. After upgrading to Windows 7, even level 2 is too bright (it is slightly higher than level 3 on windows xp even), and level 1 is too dark. The jump is drastic. Oddly, when I am in BIOS mode, the backlight levels work fine. The jumps are gradual, and like how it was in Windows XP, level 3 is a comfortable level.

I notice that I can control the backlight via Windows Mobility Centre. But even there, the levels along the slider are preset. The lowest backlight is 1, the 2nd is 15, 3rd is 29 and so on. If there is a way that I could reduce backlight level 2 on my computer to around 10 or 11 in Windows Mobility Centre, that would be perfect. Is there any way I can do this?

I desperately need a solution. My display drivers are up to date.

Thank you.

It seems like you are facing an issue with the screen backlight levels on your Fujitsu S6520 after upgrading to Windows 7 Professional. The abrupt change in brightness levels between preset settings is causing discomfort, and you are looking for a way to adjust the brightness to a more comfortable level, similar to what you had in Windows XP. To address this concern, you can try the following steps to customize the backlight levels to suit your preferences on Windows 7:

Adjusting Backlight Levels in Windows 7:​

1. Using Windows Mobility Center:
   • Press Win + X to open the Windows Mobility Center.
   • Locate the Display Brightness slider.
   • Unfortunately, Windows Mobility Center has preset brightness levels, which might not be ideal for your needs.
   []Using Power Options:
   • Go to Control Panel > Power Options.
   • Click on "Change plan settings" for your preferred power plan.
   • Select "Change advanced power settings."
   • Expand "Display" and then "Brightness."
   • Adjust the percentages for "On battery" and "Plugged in" to customize the brightness levels.
   []Third-Party Software:
   • Consider using third-party software that provides more granular control over brightness levels. Tools like "Brightness Slider" or "DimScreen" might offer more flexibility.
   []Registry Tweaks (Advanced):
   • Warning: Editing the registry can be risky, so proceed with caution.
   • Press Win + R, type regedit, and press Enter.
   • Navigate to HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\ControlPanel\Backlight.
   • Look for a key related to brightness levels and adjust the values carefully.
   • Note: Incorrect changes to the registry can cause system instability, so be cautious.
   []BIOS Display Settings:
   • Since you mentioned that the backlight levels are fine in BIOS mode, check if there are any BIOS settings that influence the display brightness. By exploring these options, you might find a method to fine-tune the backlight levels on your Fujitsu S6520 running Windows 7 Professional. It's essential to proceed carefully with registry modifications and consider using third-party software if the built-in options do not offer the flexibility you need. Feel free to try these suggestions and let me know if you encounter any challenges or need further assistance.
