Dell :: Is Ambient Light Sensor Working In Win 7 For You?
Nov 21, 2009I'm about at my wit's end trying to get the ALS to work in Win7 on my Precision M4400. I have emailed
Dell and their response was useless, as usual. They said that because I didn't buy the machine
with Win 7, they couldn't help me. (Even though their website states the machine is fully compatible, and even though they're selling M4400s with Win 7 installed.

Lenovo X Series ThinkPad :: X131e / Win 8.1 - Brightness Slider No Longer Working
May 19, 2013Why neither the display brightness slider nor the F8/F8 brightness function keys cause any change to the display brightness? It used to work but for the past few weeks it's not. I thought that slider was able to override any preset power settings.

Jan 5, 2009This is almost a classic problem. I just installed XP SP3 on a Vaio G11. I did everything according to Sony's plan. But the brightness keys don't work.
Is there a chance that Sony's drivers were written for XP SP2, and that SP3 is the cause of my problems?
Reason I'm thinking this is that SP3 recognized some devices that SP2 doesn't recognize
HP/Compaq :: DV6130US- Some Keys Not Working And Brightness
Apr 4, 2009My laptop has gotten into deep trouble..
Since the last few days, some of the keys have stopped working .. These are mainly the z,x,c,v,b,n,m,space-bar,delete,f8 keys.
Accidentally I minimized the brightness level to lowest level using the fn+f7 key.. and now i cannot bring it up using the fn+f8 key.
I heard that this could be problem due to some malware. However, i ran spybot and antivirus checks and nothing seems to have worked so far. Also, these keys do not even work at the boot time before any OS is loaded. So should i assume that this is a hardware problem?
Currently i am alteast looking for a solution to atleast restore the brightness level.. because its really strainful to look at the dim monitor.. Isn't there any alternative to the fn+f8 key combination?
My laptop - HP Pavilion DV6130US.. Windows Xp. about 2.5 years old.

Jan 9, 2010I have a T500 (LENOVO 2081CTO ThinkPad T500) running W7 32 bit. Been working fine since September 10. Today when simply trying to logon the fingerprint sensor has stopped working. Laptop had not even been moved, simply resting on desk and then switched on from powered off.
A few times since have received message that "USB device is being installed" with finally "USB Device could not be installed. There is a problem with your device." Device Manager showed a problem with "USB Composite device"
Powered off/on gave same symptom.
Downloaded & installed latest fingerprint software 7wf162ww.exe. Installed OK. USB device appeared to then automatically pick up and reinstall correctly. BUT still unable to use fingerprint to logon or for with Thinkvantage Client Security.
Using Thinkvantage Lenovo Fingerprint Software gives error "Cannot communicate with sensor. Please confirm the sensor is ready."
I've also noticed the keyboard around the fingerprint sensor is very warm, almost hot. As if it is being constantly turned on?
Fingerprint sensor is AuthenTec Inc. AES2810

Lenovo X Series ThinkPad :: X120e Funtion Keys For Brightness Not Working?
Mar 29, 2011I just got the x120e and I already went through and fixed it auto-brightening itself. After I hit the Fn + Home and adjusted it to my preference. It was not on the charger when I did that and I was in a darker room so I had the brightness down lower. Later on in the day, I plugged it in to charge and I went to make it brighter. The brightness is not changing however. All the oher Fn + F keys are working. Just not the two for brightness. The weird thing is, I shut the computer, waited for it to enter sleep mode then opened it up again and it was really bright and I had to pretty much squint, but again the keys were not working to lower it. I closed it again and opened it and it is again dimmer. The keys still aren't working.

View 4 Replies View RelatedLenovo ThinkPad W Series :: W540 - Display Brightness Keys Not Working / Audio Channel Commutation Gets Stuck
May 27, 2014I've got 2 separate but really annoying issues with my W540 20BH:
- display brightness keys not working: when waking up from Hibernation mode, sometimer (really, randomly!) the display brightness keys (Fn+F5/F6) don't work.... either if the display brightness is stuck on max, min or an intermediate level...Is there a way to shut down and restart the process which commands the Fn keys?
- audio channel commutation gets stuck. Normal behaviour of the audio configuration is:
1) speaker volume disabled, mic disabled
2) when plugging in a 4-pin headset, headset's volume is on, headset's mic is switched on; speaker volume is still disables.
3) when unplugging the headset, speakers' volume is still 0
After each boot, the audio channel is at 0, but doesn't commute to the headset when plugged in! I have to open Configuration Panel, realtek properties. With this window open, unplug and re-plug the headset. Now, the volume has its normal behaviour.
Any better way to configure audio channels and evenments, which is able to bypass realtek's manager?
HP/Compaq :: To Hack NC4200 LCD Ambient Light Sensor
Feb 6, 2009I have the business HP NC4200 laptop, which has a great ambient light sensor.
I generally disable it, because the screen gets too dim in nearly every situation, in my opinion.
But I noticed something strange. When the ambient light sensor is disabled, it is possible to adjust the screen's brightness at your own taste. This is logical.
But you cannot get the screen to 100% brightness. The only way to get 100% brightness is to actually ACTIVATE the ambient light sensor and get a very bright light source right into the ambient light sensor. Then the screen gets MUCH brighter.
Don't bother saying, I've used the Fn keys to control the LCD brightness. That's they way it works.
I use notebook hardware control, and with the nc4200 I can monitor the power consumption of the system in Watts. When the screen is maxed out without the ambient light sensor (which is approx. 50% of the LCD brightness, in reality) the system consumes around 10 watts of power.
When I max the screen with the trick mentioned above, the screen consumes +2 Watts! No need to mention battery life drops a lot.
But I do like that brightness! I'd like to keep it all the time. But it's impossible to apply the trick all the time..................

Jan 23, 2010I used the upgrade kit from Acer to do a clean install of Windows 7 to my Timeline 1410. Everything works great and I love this laptop... except that the brightness controls (Fn+Left/Right Arrow) do not work. It's locked at highest brightness.
I am at my wit's end trying to figure this out.
I have installed all the Win 7 drivers from Acer's site, particularly
- Newest bios
- Launch Manager
- Chipset drivers
- Intel graphics drivers
When I first boot it up, the brightness controls work fine during the BIOS steps. But once Windows takes over, the controls no longer function. In the Windows Mobility Center, there is no brightness control panel. [FWIW, my Dell, which does have functional brightness control, doesn't show one either.] All other Fn-combinations, like volume control, work fine.
