I'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.
Anyone know if Dell has this up their sleeves for future release? I see the ambient light sensor service in services.msc and I really want to use it!
View 6 Replies View RelatedI 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..................
The ambient light sensor on my M3800 seems to Think the room is darker than what it actually is, so the display is Always too dark, even if I turn the display brightness to maximum. I cannot find a way to turn off the sensor, not even in the bios.
I'm on windows 8.1 .......
It seemed to stop by itself after an apple update. Am on 10.6 with no other issues so far. Any way I can remove the update?
View 5 Replies View RelatedI 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
I have a Dell n5010 laptop.... sometimes I have seen that laptop is getting shutdown automatically after 5-6 minutes of powered on. Lots of internet search I came to know about HWiNFO software which shows cpu temperature and fan speed.... I have seen sometimes cpu gets heated up but the fan is not started yet causing overheat issue.. so as shutting down the system... my bios is up to date as per dell website latest bios driver version A15... I am sensing that that the thermal sensor may be not working properly always... Please note down not always it is happening sometimes it is happening...???

View 7 Replies View RelatedI am using hp pavilion dm4 1265dx. running in win 8 os. my finger print sensor not working .....
View 6 Replies View RelatedJust purchased a Pavilion dm4 notebook that came with the Validity Fingerpring scanner. As soon as I bought the laptop, I was quick to install Windows 7 Pro 64 bit as my work requires the extra features in Win 7 Pro. The stock OS that was pre-installed was Win 7 Home Prem.
So here is my issue, the fingerpring scanner wont work. I have the proper driver installed from hp's website (found here) and after rebooting, it still does not work. I have installed the hp Support application that scans my notebook for the latest drivers and found no updates needed. I have not tried rolling back the driver as the option is not available (only one driver was ever installed anyways) and I have also tried uninstalling the driver, rebooting, reinstalling the driver, rebooting, and it still will not work. I have also tried doing the same just previously mention but this time running the installation as an admin (right click, "run as administrator"). Still nothing.... I also tried navigating to the driver folder on C: and then runing the application as an admin, but still come up short handed....
Sometimes the light will come on like its working, but when I go to use it to enroll my fingerprint it just won't do anything.
Is there another piece of software besides the drvier that I need to install to get this work?
I have a Pavilion dv7 (dv7t-6c00) CTO Quad Edition (Product # A1L77AV) that I cannot get the Validity fingerprint sensor to work after installing Windows 8.1 Pro 64-Bit from scratch.
The Windows 8 drivers that are available for this model do not seem to work. Other Windows 8.1 drivers available in HP site do not seem to work either.
The device shows in Computer Management as working, I guess using a Microsoft Driver. The device shows as 'Validity Sensors (WBF) (PID=0018)' under Biometric devices.
After i did update to Windows 8.1 my Fingerprint Sensor Driver not working anymore ! My laptop is Envy-Dv6 7300 ex
I tried to download last update Driver for Envy-Dv6 7300 ex Validity Fingerprint Sensor Driver "sp58900.exe" file but not working !!

I'm currently having issues with a HP Envy dv7, I'm currently running windows 8.1.
I had a little of trouble with my original hard drive (physical damage) and had to replace it, obviously I lost my HP recovery partition and all the extra drivers that come with it,is there any way to get them? And also i can't seem to use my Biometric device since I don't have HP simeple pass , I tried downloading one from other post but it didn't work.

View 2 Replies View RelatedI currently have an issue with my original X1 Carbon (2012, 3443-CTU) light not working on the LCD. I attached an external monitor to the laptop and it works without issues so it's not the motherboard. Under the right lighting conditions and angle, i can see very very faintly my desktop background.
This leads me to believe that the screen inverter is damaged, or the lcd. Since my ultrabook isn't under warranty, i believe the best course of action is to find the screen on ebay and replace it. [URL] ....
Is replacing the LCD as easy as it sounds? It looks like i need to remove much of the parts underneath the keyboard panel, and remove the LCD bezel and replace the screen. Is there something i'm missing?
Some keyboard keys didn't work properly.
I opened the laptop (Pavilion G6 2241sa) cover and saw that keyboard cable was loose. I reconnected it properly, closed the cover and switched laptop on. Now, all keys are working fine, BUT CAps Lock light is not working well. Key is functioning, but when I press it - the light come on, but as soon as I release the key - the light goes off. Light doesn't stay. Also when the actual function of caps lock is on, when I press any other key the light come on the surface of Caps lock key but it is dim.
I rechecked keyboard cable again - all is fine, but Caps lock light doesn't stay on when pressed. I do practice typing for the last 3 months for few hours each day, so I guess it also affects the life span of my keyboard.

Today i have found that when plugging the mouse in one of the USB ports on the right side .. it does not work but the mouse gives light .
I tried it on the USB Ports on the left side .. it works well ...
Okay so my first question is this: Right now my wireless light is on showing that it's wireless, but if I close my laptop, or if it goes to sleep, and then I go back onto my laptop the wireless stops working and the light is off and it won't go on when I move the switch. I have a Aspire 5590
My second question is: I've hooked up a second monitor to my laptop I checked the settings and it works like this, if I move my mouse to the right and keep going, my mouse appears on the second screen. How can I make it so that the start menu and everything goes from the first to the second screen that way I can close my laptop, cause if I close my laptop screen it disables the second screen also/
I have a Latitude E6510 that will not start. When pressing the power button, the power light goes on for about 5 seconds and then turns off. I also notice the battery light flashes a few times when re-connecting the AC adapter.
Removed the battery, held in the power button 30 seconds, but still not working.
We have had this laptop about 6 months. About a month ago, it exhibited this problem. After talking to Dell Support, they recommended a system board replacement. The laptop was sent in and the board was replaced. When I got it back and tried to start it for the first time, it did the same thing. I then pressed the Latitude "ON" button, and the laptop started.
Now it is doing the same thing, and I find it hard to believe that another system board is bad. I am suspicious about this "ON" feature, that maybe the laptop is "stuck" or something trying to get into the "ON" mode. Or maybe it is just trying to get into "ON" mode.
I am not sure what the "ON" feature does, but I have noticed a few other posts on the internet of users having the exact same problem. Again--I find it hard to believe a second system board could be bad.
I have had my xps 15z just nearly two years (out of warranty) an today it won't turn on. The battery light does not light up and neither does the light to indicate if it is charging, when I press the on button nothing at all happens. The green light on the plug transformer is on until you plug it into the laptop when it immediately deilluminates. I am trying to establish if this is an issue with the plug or the laptop hardware, I could not find a solution and I only have my phone to look on now my laptop has died.
Moreover I am very annoyed with the quality of this range topping machine, when it first came the hard drive had to be replaced, the dell rep who fixed it managed to break the battery indicator lights which I had to take it apart to fix. When you consider the wireless issues, the focus losing problems which made it impossible to type until I found which dell programme to uninstall to fix and the crackling speaker issue which I still not found a solution for, this is not good enough.
My first month with this brand new notebook was problems it gave me a blue screen and shut down on me. I thought it was normal being that it was my very first notebook. My hp pavilion notebook is only 3 years old but it now it has a blinking caps light and a orange light on the wireless key. I have tried to hard reset it but nothing works. I was use to it shutting down on me and restarting again but this time it would not come back on. I call Hp tech and now I'm being told this computer is obsolete and can't be fixed.

Does anyone know how to disable the infrared sensor on an XPS 1645?
I ask as I often use the laptop while also watching a media pc and the remote control operates both the laptop as well as the media pc and it's damned annoying.
All of the items referring to the infrared receiver in the device manager can't be disabled so other than sticking a piece of tape over the sensor does anyone have any ideas?
what i wanted wass to fix/bypass the sensor without having to replace the damn board. i couldn't even find a single post staing where exactly the sensor is on the board.
my problem specifically was that beer got spilled on the keyboard. after a while the machine shorted and shut off. I have a Dell Inspiron 9300, with a 1.73 ghz Sonoma CPU. i left the laptop off for two days so some of the liquid would dry out. after some problems and a dozen reboots i got into the bios, then finally through to windows. everything was fine except that the CPU was working at a very low frequency. also the fans were continually at highest speed. the CPU was being reported between 101 mhz to 503 mhz, depending on the software. it was being recognized correctly but showing to operate at 202 mhz in the system properties panel. what was really striking is that the notebook harware software i had installed was reporting the CPU temperature as 85 C. I tried various software to manipulate the CPU frequency to no avail. The temp was a constant 85 C, although i could tell that it was not even close to this temperature since i my laptop was partly disassembled and i could feel the surface of the heatsink with my hand; it was cool.
I finally surmised that the problem was with the thermal sensor on the motherboard. it had probably shorted or got soaked and was reporting the highest temperature it could as a safety measure, thereby limiting the CPU to a very low frequency and not allowing it to throttle above 503 mhz.
My last option, save for replacing the motherboard, was to find the sensor chip, clean it, dry it and hope that it would work again.
But this is not what solved the problem. somewhere on the net i came accross a code, that when entered on an Inspiron 9100 (an older laptop, with a different chipset) would bring up the Thermal Management screen or something like that, which is certainly not accessible via the BIOS. I was playing around with the settings on a program called Hardware sensors monitor, again to no avail, when i finally decided to enter this code:
FN key + zxcvasdqwer. almost the second i pressed z, or maybe after x, the high speed fans shut off! after a short while they kicked back into operation but at a low speed, just like they were supposed to. the program hmonitor began reporting a more realistic CPU temp. i tried to play a high-def movie file and finally it played normal, without any lag or stuttering! as i played it, the fans kicked into higher mode, and the temp which had been steadily rising, began to drop. the program, and most other programs were still reporting the cpu at 202 mhz, windows system properties as well. but since it was playing a 720p video file normally, it had to be much higher than that. i did a reboot and voila!
all monitoring software are now reporting the CPU at 1.73 ghz. the system temperatures are perfectly normal, and at idle the CPU goes as low as 20 degrees C. The software Speedfan, however, is still giving an error regarding the sensor chip on the motherboard.
I seemed to have fixed the severe thermal sensor problem by a few keystrokes, without having to replace the motherboard or even the sensorchip. in fact, i didn't even have to find the sensor node and clean it.
I came accross more than a dozen people who had a very similar problem to mine, with the temperature being reported at 85-86 C, for no reason. At least those who have a Dell notebok might be able to solve this problem.
Alright, so today I decided to try out I8k Fangui with Intel thermal analysis tool, and my was I shocked. My M1710 was registering temperatures of 97 degrees centigrade before I shut off the thermal analysis tool. I would've probably went way past 100. I got a non overclocked T7600G.
