I bought a new Dell Inspiron 15 7000 core i7 with touch display about a week ago. I've noticed that on occasion, especially when running on battery power, the screen flickers slightly.

View 3 Replies View RelatedI have a new Inspiron 7000 series that I'm setting up. I have a restore app running to download a sizable amount of data from my old backup to this new computer.
Although I have the laptop plugged in and told it to NEVER sleep when plugged in - and I adjusted the hard drive (advanced power management) to stay awake for 120 minutes, it still seems to be going to sleep after a short (less than 1 hour period of time).
I have to hit the power button and wait for the screen saver, then I swipe it out of the way and must login to my laptop. The restore application stops running when it goes into this sleep mode.
Frustrating as my settings all seem to imply the system should stay awake.
Just got the 1920 x 1080 version of the 13" inspiron. The left and right edges (about 5-10% and not top or bottom) of the screen are about half as bright as the rest of screen. Also on closer inspection I've noticed that on the left hand side, the middle part of the rubber edge is squashed in. Is this pretty much normal for these laptops? I'll see if my camera can capture these details.

When the AC adapter is unplugged and I'm running on battery power the whole system lags. It also turns of when unplugged without warning after about 15 minutes.
Also, I get these error messages in my event viewer a couple of times an hour:
Log Name: System
Source: ACPI
Event ID: 13
: The embedded controller (EC) did not respond within the specified timeout period. This may indicate that there is an error in the EC hardware or firmware or that the BIOS is accessing the EC incorrectly. You should check with your computer manufacturer for an upgraded BIOS. In some situations, this error may cause the computer to function incorrectly.
I am using Dell Inspiron 13 7000 2 in 1 laptop for last 2 months. It is a nice laptop to use.
But I have an issue now. It is that the touch screen touches itself automatically on the left side of the screen over top to bottom. It occurs occasionally and it is annoying. I can't control the mouse when it occurs. When I restart the system, it stops.
I can't find any solutions for that. I did calibrate also. It didn't worked.
It touches all over the left portion without gaps.
My Inspiron 13 7000 2-in-1 laptop, after having the screen and hinges replaced due to other problems (ghost touches), now won't auto rotate the screen when in tablet mode. The keyboard is also functional when the screen is pushed back past 90 degrees, so when the keyboard is on my laptop but the screen is facing me. This doesn't happen in true tablet mode however.I've tried reinstalling all of the up-to-date drivers; chipset, BIOS, along with the ST Microelectronics 3-Axis Digital Accelerometer Driver.
There are a number of issues I can highlight that stop this from working;
1) in device manager there is no entry for ST Microelectronics 3-Axis Digital Accelerometer Driver, nor Accelerometer or anything I presume makes this function work. There is a Sensors collection, but nothing in there I think is it,. There is also no 'Unknown' device listed.
2) I should see PopUp_DM.exe in the running services and in the startup selection of programs. This is nowhere to be seen.
3) I don't appear to have a "Sensors" applet
4) when I choose 'Normal Startup' in msconfig & then reboot, it goes back to the bottom option, Selective startup. Is this something I need to do via the Dell BIOS Advanced Options?
Other than doing a full restore, which I loathe to do again as already prompted by Dell previous to this issue, what can I do? A bit worried that when Dell replaced my screen they didn't refit or include the accelerometer!
When I pull the power cord to switch to battery power while in Windows my lcd goes to black. The only way I get my video back is a hard reset and reboot. Later on I tried this and everything was back to normal. Why is this happening? Is this some weird standby?
Dell Inspiron 1505 Bios A-14
I have a Dell Studio 1737 that is having problems shutting down. While it's running; if I tilt the screen slightly the power light will flicker on and off and the laptop shuts down completely. When I tilt the screen again, the laptop will power back on and start booting up without having to press the power button. I have all the power settings set to never and set the laptop to do nothing when I close the lid. Seems to be a short in a power cable somewhere in the screen? Running Vista 64 SP2. This laptop is a month out of warranty. Does the whole screen have to be replaced or can the power system be replaced?? Haven't opened it up yet to see how the power system is set in the bottom of the screen.
View 2 Replies View RelatedHP Envy 15" TouchSmart laptop running Windows 8.1. This is a problem that just started today, it has to do with the screen and fans where the Power LED lights up white, just as when the laptop is running properly.
My laptop was opened and turned on, functioning properly. I had NetBeans IDE running since I wanted to work on the second part of my current CS 137 (Programming Principles) assignment. Because it was almost time for my lecture, I closed the laptop by simply moving the screen back down onto the keyboard, where it goes into sleep mode. (Anytime I flip up the screen, the laptop is supposed to come back on, and the login sliding screen from Windows 8.1 shows up.)
When I took my seat for the lecture, I wanted to spend a little bit of time to work on my programming assignment. However, upon flipping the screen back up, instead of having the login screen show up, I encountered the problem: the Power LED is showing a white light, but I can't hear the fans running from the vents on the left side of the laptop, and the screen does not turn on. I did try to hold the power button for several seconds, and once at least 10 seconds, except that the Power LED keeps on showing a white light. The light for the Wi-Fi board does not show up.
Whatever it is, I don't want to pull the battery out because I did do that on my last laptop, and it was from there that I couldn't turn the old one back on again. If I pull the battery out from the Envy laptop, it'll short-circuit the connections from the battery to the computer, and thus several components will fry. For now, what I'm doing is leaving the laptop as is to drain the charge on the battery. And then, once I notice that the Power LED does not show a white light anymore, plug the AC adapter, then try turning the laptop back on using the Power Button.
My inspiron 15r 5520 is 1 year old and now it shuts down suddenly when doing slightly stressful tasks like playing games ,which i didn't encounter in the starting months.
But from week whenever i play a game it shuts down in 10 min .Later i tried few suggestions from dell forums on overheating and found that the laptop runs fine on battery and as soon i plug in the adapter it turns off in 10 min .I checked if it is a overheating problem and found the cores temp at around 60 degrees celsius when idle and it crosses 100 when i play games plugged in and around 95 degrees on battery.
I then checked if its due to dust but everything is clean and i use a cooling pad so this is quite abnormal.
I have all the updated drivers and bios, fresh installed windows again, so what to do...
My T440p slightly adjusts the screen brightness depending on what is being displayed. For example, on Chrome, one page might have more images, so the screen slightly adjusts brighter or darker. Another page it might slightly adjust again. And it does it when scrolling down a page as well. It is distracting, and I want to disable it? I'm on windows 7.

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 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 Optimus
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 properly
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.

View 4 Replies View Relatedi 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.

View 5 Replies View RelatedI'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)................
