Dell :: Vista Owner With Flicker
Dec 2, 2007
I have had a major problem with my M1710 having a fit when running on batteries!
theres a slight flicker when running aero on vista, but the computer has a major fit when running Studio 11 from pinnacle.
have had a great deal of discusion with dell and Tech support with out success.
they suggested new mother board and 7950gtx card!
anyway through reading alot of posts on the forum i tried increasing the clock speeds of the 2d setting on the graphics card
the core is now set at 150 and memory 200
i tried it at 100/150 as suggested on another post.
However 150/200 has created significant performance increase when editting on pinncle studio 11! and vista areo runs smooth as silk
Increasing the Clock speeds cures the flickering problem!

I hope its a problem of the LCD inverter, and not all the panel.

You are correct. Here is that thread.
At this point we are looking for common factors. Post up any other useful information you can think of.
Does anyone know the Hz of the backlights?
Does this flicker still happen on an external monitor?
Human vision factors:
Most people can see flicker at about 80 hz. This is most noticeable in bright light and in the peripheral vision areas. Most people adjust to the flicker rate of their local power so that they no longer notice the flicker.
Most people can see an animation as continuous movement at about 20 Hz. The brain tends to understand that it is seeing an animation and assembles it as movement. On things that are not moving, the flicker is more noticeable as your brain has nothing it can assemble the flicker into.
Some people have said that they can see the flicker while other people around them can't. This could be because some people are less sensitive to noticing flicker. This could also be because the other person is looking at the screen from farther away (say, over the shoulder of the owner) and the screen is centered in their vision, not in the peripheral vision areas. If you are one of these people please let us know it your test persons have actually sat directly in front of the laptop, just like you normally would be when you see the flicker.
I suspect the flicker is actually due to the Hz of the backlights, not the actual refresh rate of the screen.

I put this in a new thread because I do not think this is a real problem but how this screen is.
A lot of people report a flicker problem but a flicker problem when it it exists is a major issue with the screen refresh.
What I see is in very light or dark screens on my 1555 is a just detectable "Waviness" of the screen, Almost non noticeable looking directly.
Worse at low brightness
is this just the nature of LED back lit screens? I cannot find much on the internet about this I guess due to so few computers had them prior to these models.

I just received this machine, and so far so good.
There is some screen behavior that has me a bit confused though and I'm hoping someone here might have thoughts or advice about it.
Every now and again, the screen gets just a bit dimmer for just a very brief moment, not much, just a bit, and pretty quickly, and then comes back to normal. It almost looks like it wants to go into it's "power saving" mode or something, for a moment, and then back out .....

What is happening with the laptop, sometimes I noticed my laptop screen will flicker(or a bright flash as if someone was taking a picture). When I go to the event viewer it tells me Desktop windows service manager has been disabled by the windows system assessment tool. I'I have the nvidia graphics card + Intel(using optimus technology),running windows 7 professional 64 bit.
I forgot to mention when playing videos I think the graphic card makes a strange noise like there isn't enough power or something (Not 100% sure)
I have nvidia gt555 with intel OptimusÂ
Intel 2670m
8GB of RAM
Windows 7 professional
I tried to do a fresh install of windows 7 but the problem still persists and I cannot test it since I have deleted the recovery Drive. How do I test if the graphics card is working properlyÂ

I posted a few times in other threads and received a lot of good advice on which laptop to buy. This led me to the e6400 which I ordered from the outlet.
Received it over the weekend and got it up and running. Though not as stylishly groundbreaking as some, it has a nice sleek, cool look.
It is a business laptop afterall. I will agree with others on the speakers, pretty poor, even for a business laptop. But, other features are nice.... backlit keyboard, screen, keyboard layout/size

On my Acer 5920, the screen flickers off and on when I plug up to my projector to give a power point presentation. I have called Acer NO-HELP; they said it was a 3rd party software issue, which was not true, because there is no software- it is plug and play. I called Epson; they suggested to chage the refresh rate to 60 and I did to no avail.
There final word was that it must be the Graphics Card.

I found a couple other reviews where people said they had a noticeable (more so on dimmer settings, for me) screen flicker with their timelines. I have the 1410 with su2300 proc. Anyone else noticing this problem? It's enough to distract me, which can be annoying, but I'm a bit of a perfectionist when it comes to the visuals.

my white 13.3 inch macbook has developed like a flickering problem, its a good few years old, max memory on this one is only 2gb's. well anyways, the screen, it has only done it intermittently but when opening it for wake up, or when the screen dims, it ocassionaly does like a flicker thing, but only for a few seconds, then it stops. my guess, its the screen invertor.

i was working on my thesis in a completely dark room and realized that the screen on my macbook pro flickers even if the background is completely white. this annoyed me to no end since i have sensitive eyes, so i set out looking for a temporary fix before i try and get apple to replace my panel. anyhow, luck has it that there is a fix out there that at least temporarily stops the flicker (i havent seen it posted on nbr before, and my apologies if this is old news): press ctrl-shift-eject to reset the screen. once it goes blank, hit any key and your display should be good to go. worked for me and my screen has been flicker-free for ~30 minutes.

I am from Belgium and since yesterday a proud owner of a m1730
After weeks of surfing the net to get the best bang for buck I got myself a brand new m1730 with sli 9800m gt, 6gb ram, a 2,5Ghz duo, blu ray, etc... for just 1839€. Believe me this is very cheap for this laptop in Belgium.
I also game on my Imac (which I bought to do mostly Lightwave and 3d coat) from 2008 with a 8800gs (in reality a 8800m gt) and 3,06 ghz core2duo .....

I've been plagued with this problem for the past month and a half at least, so much so that the laptop has spent the last 3 weeks with Acer and their technical support team in Plymouth (I only got it back last week).
The laptop was sent off with a fault to the screen. It intermittently flickers, mainly when the screen is moved, but sometimes not. The laptop was sent off to Acer 3-4 weeks ago and was returned last week. A report was returned with the laptop and reads as follows:
Problem Description:
SYSTEM FUNCTION - SYSTEM FAIL TO FLASH BIOS
Repair Description:
STORAGE - OPTICAL DEVICE WILL NOT READ/WRITE
Diagnosis/Repair Details:
fitted new ODD and middle cover
Spare Part(s) Replaced:
ODD HLDS SUPERMULTI DRIVE 12.7
COVER.MIDDLE.W/MMN/EKEY-BD
As you can imagine, this report left me completely perplexed but I assumed that somewhere within that they had fixed the screen problem and left me with a fully functional laptop again. And of course I'd been without it for 3 weeks and just wanted to turn it on again!! lol (On a sidenote, I had asked them to check the disk drive also, because back when I first got it, it struggled to read any type of disk. This explains the apparent replacement disk drive)................

Priced from $649 U.S., the Studio 14z is available now online and over the phone in the U.S. and Canada.

I have a new Dell M4400 Precision running Windows Vista 64bit. Th only function that works with the fingerprint reader is pre boot and windows log on.
I am not able to log onto web pages or applications. The fingerprint reader (in my case the FIPS unit but both are effected) is not attached to the system and will not detect as a biometric device. The fingerprint reader is connected to a unit called a Broadcom USH (Unified Security Hub). Since the unit is not detected as a biometric device you cannot use it with any fingerprint software such as PSQL (Upek's Protector Suite QL) or the built in software with Windows 7. The only software that it works with is ETS (Wave's Embassy trust Suit) which officially from Wave does not support and will not support 64bits OS. The ETS software however does not work even when a 32bit OS is used, Well at least not work in a practical manner.
I AM IN CONTACT WITH DELL LEVEL 2 SUPPORT AND ENGINEERING. BUT NEED HELP FROM OTHER DELL OWNERS TO FORCE DELLS HAND TO RESOLVE THIS POOR DESIGN FLOOR WHICH ONLY EFFECTS THE NEW DELL LAPTOPS.
FACTS KNOWN SO FAR
1. The Fingerprint readers used are standard USB readers
2. The port on the USH is a standard USB port.
3. The fingerprints are stored in the fingerprint unit.
4. The fingerprint reader will still work with the TPM disabled
5. The FIPS and HSPD security is part of the UPEK reader and has no bearing on the broadcom USH.
6. It is the USH that is blocking the fingerprint from Windows.
7. Up until approx 10 days ago Dell did not see this as an issue. But now see it as a high priority to resolve and are talking about developing a 64bit ETS.
8. Being able to use PQSL with the FIPS reader would resolve issues. Allowing webpage logon and application logon as all previous Dell units did.
9. The FIPS reader is supported by PSQL 2009 confirmed by UPEK.
10. Not confirmed only commented by a UPEK Tech that they are trying to resolve the broadcom compatibility issue that effects Dell.
11. The Broadcom USH controls the Smartcard and Contactless smartcard readers. The fingerprint reader is only connected to a USB port on this device which is restricted from the system. Like a locked port on a USB hub.
12. Which with out Dell owners speaking up as a whole Dell engineering will not listen to the Dell Pro support.
HOW WE CAN FIX IT
After speaking with UPEK and Dell pro support is is confirmed that this solution will resolve the issue of the fingerprint reader not being a biometric device and all of the problem associated with this simple fact.
SOLUTION
If Dell engineering was to update the firmware on the Broadcom USH allowing the USB port that the fingerprint reader is attached to be seen by the system then all would be resolved and windows would see the fingerprint reader as a biometric device instead of Broadcom USH w/ fingerprint touch sensor. This would work the same way a USB port on a hub sees a device. For example a memory stick on a USB hub intergrated into a keyboard is not seen as a "Keyboard w/memory stick".
CONCLUSION
Dell pro support has already requested the update from Engineering and was told they are looking into a 64bit ETS. This does not add inbuilt support for windows 7. Unless Dell owners speak up together and in numbers ENGINEERING WILL NOT LISTEN. So please reply to this post if you are not able to use your new fingerprint unit in the practical way that a HP, Acer, Toshiba or owner of another brand laptop can.
