Dell :: The Free Fall Sensor Didn't Sense Anything
Mar 12, 2009
yesterday my e6400 fell from 5 feet! 1.5m! I almost caught it but it just fell. Fortunately it fell flat and there was en empty box of cleenex that fell with it and fortunately made the impact with the ground a little softer.
But STILL, I have a free fall sensor that did absolutely nothing. I picked the 6400 up and it just kept running as usual. Nothing happened to the machine, which to me is a great sign of durability, but AFAIK the HDD should have shut off, otherwise what's the point of having a free fall sensor?

I 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

When I press the start button on my Latitude c600, 2 green lights light up on the right side for power and hard drive, as well as the 3 lights for the keyboard. The lights stay lit for about 5 seconds then go out.
However, that is with the external power connected.
With just the battery, it lights just as above, but then blinks off and then on again for another 5 seconds. Wash rince repeat.
Additional information:
I removed the hard drive weeks ago to use in another system and I don't know if laptops fail to boot if there is no hard drive detected.
Before you ask, I tried reseating the memory.
Although I have worked for years on desktop computers, I have never dismantled or provided support for a laptop.
Also, I cannected an external LCD but that means nothing untill it boots.

I updated the HP Assistant and one of the items listed was an update to HP Cool Sense.
I downloaded the file and installed it. No snowflake icon at the lower right.
I went to Start and typed in HP Cool Sense in the search all programs and files box. No snowflake icon. There is an entry at the top listed under Programs, so I clicked that.
Error message popped up: Windows cannot find C:Program FilesHewlett-PackardHP Support

I posses a dell 9400/e1705. Currently I have 2GB of RAM installed (in one piece). I was thinking of installing an additional 2GB. I was wondering if there is any sense in doing so.
First of all I have 32bit system, so the whole amount (4GB) will not be recognized. Secondly I am unsure if I will notice any increasement in performance. I mainly use the computer for photo retouch in Photoshop (I operate on big RAW files) and sometimes I install games.
A friend of mine said this would a good idea beacause even though the system will not see 4GB the chipset will allow the two memories to work in dual channel (If i were to add just 1GB I would have a total of 3GB but no dual channel).

i have a problem with my precius Dell Inspiron 17R SE 7720. I have actually 2 HDD of 1TB. I want to install a mSSD into the mSATA conection. The mSSD is one SAMSUNG EVO 840 of 250GB.
My problem is... all my conections are SATA2?????? I read in this forum than Dell Inspiron 7720 are 2 SATA3 conections, because the HM77 supports only 2 ports of SATA3... but when i passed "CrystalDiskInfo", i see in all drives SATA 300 (2 hhd and 1 msata).
My laptop didn't have SATA 3 conection?

I had this plugged in but no charging issue and I called, they said it was the MOBO or the AC. So the guy came today and put in a new MOBO and used a new AC, but it still won't charge.
So he called Dell and they said it had to be the battery (even though we don't get the light 1/3/5 indication on the battery meter), and that since I was out of the 1 year battery warranty I would have to pay.
Well here is the thing, I have a freaking 4 year warranty on this thing, and it is barely over a year old and the battery already failed? WTH is up with that? Also, the guy said my battery warranty expired in March, but I didn't even place the order until June and I didn't get the computer until July 18 or even later. And they won't approve my battery replacement, they said if I called before the end of July (like 2 days earlier) I would be able to. This is ridiculous.

My Latitude D800 laptop recently had trouble to turn on. When pressed the power button (no matter how hrad or hard long to press), nothing happened, totally dead, power light didn't turn on at all. I tried with battery (two batteries) only, AC power only and both, same thing, but sometimes it could be turned on when I waited for a while or came back later and tried again.

I just bought a new sony laptop and when I first started it, I forgot to put in the battery and just plugged in the AC adapter. So near the end of the setup of the system language and everything, I got a blue screen saying something about a power state failure and the computer shutdown. I immediately put the battery in and turned back on the computer and after a while, it was fine. So should i be concerned if i permanently damaged the computer or anything?

The screw that holds the bracket in place at the top of the compartment, I stripped it.
I used the correct screwdriver but the screw is too tight. I am going to use a drill with a tiny drill bit to see it that will spin it.
Does anyone know if hard ware stores sell screws as tiny as those? I want to replace the screw but can't seem to find it at the Rona.

I have an issue with my Inspiron N5010 screen, it doesn't work when switching on my laptop on Battery or AC mode. It happens a lot of times when I turn on the laptop the power button, the power indicators at the bottom turns on normally and the laptop is running without any weird sounds. But the screen is pitch black even doesn't show up anything when I concentrate on it in with a lamp or any light.
When I press the power button again even after 5 mins from the start time of being running the laptop just turn off immediately and doesn't take time to switch off as If the windows wasn't loaded!
I was resolving this problem by disconnecting the AC adapter > removing the battery > Pressing and hold the power button for 20 seconds technique.but today it doesn't work anymore, If there's anything I can do to get the screen backlight to work normally ....

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.

Just under 3 years ago I bought an Inspiron 6400 and it came with a free upgrade to a 3 year warranty, I'm so glad about that now.
This week the screen on my Inspiron stopped working so dell is now replacing it with a XPS M1530, A very nice upgrade

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.

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.

I am considering the Dell Vostro 1520 as a laptop but I am confused about the windows upgrade option (I would get Vista Home Premium to be able to get it as a start). Here's a link to the page:
http://www.dell.com/us/en/business/n...20&s=bsd&cs=04
I was under the initial impression that any dell laptop sold in the few months before Win 7 released would be eligible for the free upgrade.
But when I look in the lineup there's one that says "Windows 7 ready" for an extra $140?? Is that the only one that gets the free upgrade? It's not really free then and why not just buy it separately?

on my m4400 it seems the fingerprint software is only used to log on to windows.
my girlfriend has an acer with a fingerprint reader, she can use it to log on to websites etc...
does the dell software allow me to do this? or do i have to download some third party software?
what is the difference between a UPEK fingerprint reader and the non upek one? lol... dell has those two options

Has anyone had any luck getting dell to upgrade anything because of shipping delay? Or offer discounts?
Specifically, I am thinking about trying to convince them to upgrade my warranty. I ordered a studio 17. the basic warranty is 1 year limited warranty with 1 year return to depot service. This is included in the base price. When I placed my order i upgraded (for $198 CND) to the 2 year limited warranty, with 2 year return to depot service, lojack+ accidental damage service.
I have been given the usual order delayed bullcrap like most of you. But is it possible to use this to get them to upgrade it to the 2 year NBD onsite service, lojack, and accidental? ($80 value over my original 2 year return to depot)
I am going to give it a shot this week when I can manage to find the time to sit on hold for a few hours. I will let you know what comes of it.
Anyone try anything similar? share your results

Does anyone else have a problem registering for the free upgrade to windows 7. Whenever I try to validate my service tag it says I should wait 10 days because my order might not be in the system. I order my E6400 early mid July. And it also says my system isn't eligible when it is.
I've chatted with a Dell person online and he was no help. He just gave me a number to call. I called that number and I had to talk to a lady with an Indian accent that didn't understand what I was saying. And I got transfer a couple times until some guy gave me a number to call, but I couldn't because they were closed or something. Now I call that number and they give me another number to call. Everyone keeps saying "I am not trained to handle this issue."
