My Dell 7720 has uneven screen backlight on the edges, is it normal? Do all the 7720 dell laptops has the same issue with the screens, or it is only my problem?
Here is the video where I make screen darker and brighten: [URL] ......
I recently purchased an Inspiron 7720 in October 2012. A week ago, the laptop started freezing up while playing world of warcraft. I checked my Nvidia video card and there were some updates. I installed them and the computer started working normal again. On Saturday, while I was using Skype to transfer a file, the computer gave me a white screen and I had to hold down the power button to get it to shutdown. It rebooted and was working normal again. Then yesterday (Sunday), while using video chat on Skype the computer screen went into a flashing color pattern and I had to hold down the power button to get it to shutdown. Are there any diagnostic tests that I can run before calling Dell's tech department? I believe it is a video card issue but not completely sure.

View 7 Replies View RelatedDell Inspiron 7720 (17R SE) approx 2 years old, just started having problems about a week ago when turning on the computer. LEDs flash and dell quickset buttons light up; but then process just dies, screen is black and only the LEDs by the power symbol and on power buttons are lit, never reaches the Dell logo screen, no fan sounds or anything.
At first, hitting the power button to turn off then back on and the second time the boot process would work. Then it failed to do that, so I had to remove the battery, pull the power cord and hold the power button down for 30 sec's, and then it would boot normal. Now even that does not work, just have to keep powering down and re-powering and after a random number of times, 10-30 it finally boots normal, every once in while it will work first try. It seems to be getting worse.
I have used the Dell Diagnostic on boot (though it took many tries to get into the ePSA, that did not detect any problems. When I use the Dell Support Advanced, no problems detected, and I specifically rand the Motherboard (which included CMOS test) and those did not find any problems.
If I put the computer in sleep, it comes back fine. It is only when I shut down, laptop just will not boot until I hit power on (fail) / power off repeatedly until finally, as if by luck it works fine.
First off before I get into the problem I want to say that I am an experienced computer technician having worked on hundreds of laptops in the past. So I'm very familiar with the problems and solutions for them.
I just want that disclaimer to be up front that I'm not a rookie seeking laymans terms or solutions.
Anyway, that aside. A customer dropped off an Inspiron 5160 last week. The system wouldn't half power on he said so after testing, I determined that the AC jack was 'broken'. Sure enough after disassembling the computer I could see on the bottom of the motherboard where the AC adapter had been knocked loose.
I replaced the motherboard and immediately noticed that the screen would display the BIOS Dell logo for about 5 seconds, and then cut off.
With a flash light I could see the data images on the screen, just no CCFL light from the bulb to brighten the screen.
When i press the power button laptop seems to be powering up and running but the screen is black. The LEDs for power and disk are on and i can enable the keyboard back light. If i try to turn the laptop on again and again then after some time it boots up ok and then works without any problems, at least until i turn it off. I tried to connect an external monitor but it didn't get any signal.
I'm not sure if it is connected but i think it starded after i did the system recovery. I use Windows 7 Home Premium SP1.
new screen/inverter/ backlight installed. NEW screen still black, but visible with flashlight. Went ahead and got ANOTHER inverter off eBay and tried that - screen still black. Haven't ever replaced a backlight, and the operation looks delicate (and expensive to HAVE done) ...

None of the repair options work from the boot options etc, so I need the OEM win 8.0 installation disk, so that I can at least boot to safe mode and maybe correct from there once out of the boot loop.
On my old XPS, when the screen turned off, the keyboard backlight would turn off with it automatically. My new Inspiron 17 does not do this, and I can't find anything that seems to control the behavior. Is there a way to do this?
Alternately, is there a software solution to control the keyboard backlight?
I have found that the base of my M1330 is uneven at times, sometimes it is even and all the rubber feet touch the table and sometimes the bottom left corner is 2 to 3 mm higher. This is tested on the same surface all the time and I have tried other even surfaces as well and see that the base is definitely uneven at some times. It is weird that this happens at random times, I think it might be the changing whether and the case shrinking or something during cold temps and expanding at hotter temps. I also think it might be some tight screws or loose ones that don't keep the M1330s base in the correct shape. Any one else have this problem? I have tried bending the case and it will fix it for a short period of time but the problem will come back.

The surface itself is flat, but the left side sits a bit lower than the right side, as if the whole touchpad is tilted to the left. The right side is flush with the surrounding aluminum, but the left side is maybe .5mm lower. Is this normal?
View 9 Replies View RelatedI got my E6400 last week and I found that everything all right except the color of LED screen, it's awful.
The color of the screen is pale, i had tried to calibrated the graphic settings but it doesn't improve too much.
Also, i saw some posts here said that the LG screen is better than the Samsung screen, but I can't agree with that because my screen is LG.
Is it normal for LED backlight screen that the color is more pale than the CCFL backlight screen or just the screen of mine had some problems?
I bought this laptop in December and have had no problems with it. However, today I shut down and updated and then a few hours later i tried to turn it on but it does not work. When i turn it on, the screen shows the dell logo and then turns black. After a minute or so this occurs again and then an empty bar appears at the bottom with text next to it that says "F12 Boot options."

Computer: Inspiron 7720-17R, i17Rse-3589BK, Intel i7-3630QM
A. I have checked the power chord it works on my older backup Inspiron17, I two power adaptors the work. the original Dell and an after market rocket fish. both work on my older model Inspiron 17.
B. Without the power chord: open the lid, press the power button, it does not turn on the computer on or light up, none of the indicator lights do not light up.
C. When I plug the power adaptor in to laptop:
1. the power indicator light on the laptop does not light up showing it is plugged in.
2. pressing the press the power button it does not turn light up or turn the computer on, none of indicator lights do not light up.
3. (Original Dell power adaptor) the blue light at the end of the power chord goes out.
4. (Rockfish aftermarket power adaptor) the blue light on the adaptor goes from a solid blue to a blinking blue light.
I have a new 17R 7720 SE- that worked great when I got it, but after all the Dell updates- the Waves Maxx doesn't work, and if I use it for more than an hour the screen turns white and the Laptop screen then goes blank! I've called Dell and they told me the 17R 7720 SE runs hot because of the internal 2gb nVidia 650 Video Card.
I spent the money for a Cooler Master Laptop cooler with 3 Fans (separate A/C adapter to run this thing) and the Cooler Master sounds like a jet airplane under the Dell- and the Dell screen still shuts off. The only way to solve this is use an external monitor... if I would have known this I never would have order this worthless Inspiron.
I write this from my trusty Latitude D630- it's never let me down... the 17R 7720 SE has nothing but trouble! Dell recommended I reformat the Hard Drive, and re-install the factory software from the System Restore Disc...
Is this the backlight? i hot glued the connector and wires in the socket into the inverter....?
I have replaced the inverter AND the flex cable (yes, the part numbers are right)
I have to shake or pressure point the left-middle of the screen for it to stop otherwise it stays unreadable...
when i hook it up to an external monitor...
I purchased my laptop a little over 2 weeks ago. After the first week I noticed that when I turn it on the dell logo will come on and then immediately go to a black screen. At that point I have to power off the back on and it boots normally. I flashed the BIOS to the A11 update but the didn't fix the issue.
View 10 Replies View RelatedBrand new Dell Inspiron 17R SE has started to switch off in a few seconds after I hit the start button. I tried going into setup using the F2 key and just doing that and exiting without saving allowed me to restart yesterday. Today, that didn't work. I had to go to Boot Options F12 and I tried randomly changing secure boot to ON and then exiting by discarding changes. That worked. I don't want to be doing this everyday.
View 1 Replies View RelatedI want to install a SSD in my laptop, a Dell 17 R SE 7720. I can see that the hard disk is right under the palm rest, on the left side.
I want to move the Hard Disk to the other HDD slot, and put the SSD where the HDD is now.
The question is, can i do this without voiding the warranty? Am i allowed?
Is there a list with what i can do / change to my laptop without voiding the warranty?
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?
Dell Inspiron 7720Bios V. A07Windows 8.
Today when I booted up my laptop, it shows the Dell logo and goes to a screen that only shows me a few things. It says "Boot mode is set to:UEFI; Secure boot:ON" Then there are two categories, "UEFI BOOT: Network" and "OTHER OPTIONS: Setup, Diagnostics, Change boot mode settings" I ran the diagnostics in ePSA and it said there's something wrong with the video card. It gives error 2000-0332 - "Video memory -Video memory integrity test discrepancy"... when I searched for this code, it said the solution is "Flash latest BIOS, retry diagnostics."
I can't gain access to downloads for my laptop :
For example, if i go to Support / Inspiron 7720 System BIOS for WIN8/WIN7 for my 7720, I get a "Drivers & Downloads Error, an error occurred while processing your request".
I've been expecting a problem recently; when I turn off/restart my Inspiron 7720 and I press F2 to load the BIOS, I notice the bar fills but it continues and loads windows normally. I tried updating the BIOS from A10 to the newest A12. If i press F12 for boot options it works fine, it's only when I press F2 for the BIOS.
View 3 Replies View Relatedafter reinstall, about 3 weeks ago when i played game i get my CPU and Mainboard to 90C. In 2 minutes, my computer shut down, i tried to start computer by power button, but it shut down in 1 sec... just flashing. After 1 minute i started computer..I upgraded BIOS, install recommended drivers also i have cooling pad which i using on HDDs.
OS: Windows 8 x64..I think it's HDD or Mainboard overheating or maybe CPU, because it has 85C too.
i have encountered another bug aside from gpu boost issue, which is currently still unresolved. Fan speed control is not going idle on 7720 SE, even when temps are very low (below 40c)... on A12 BIOS, I have to restart my laptop to be able to switch to FAN Idle speed again. These are temps iam having and fans are still on.
View 2 Replies View RelatedI have Dell 7720 17r SE for almost a year now,I remember it as a fine gaming rig.I used to play Dead Island, Fallout New Vegas on max settings and resolutions,But ever since the latest A13 BIOS upgrade and the new 314.22 Nvidia Driver.
I noticed a significant drop in performance. Almost every game started to lag when the action becomes too "crowded" (lots of enemies etc).
And as for Dead island I noticed the performance drop after 20min of play.Not sure about overheating. (It seems like the usual temp if not maybe a Celsius hotter)
Noticed gaming performance drop after updating the bios and latest GPU driver???
I've had a Inspiron 17r SE 7720 laptop for about a month now, and it's worked wonderfully. However now when I go to start it up it gets stuck at the Dell Logo screen, sometimes the bar fills up and it goes to a black screen. And the bios don´t load, only show a loading bar but never loads, i try removing the battery and turn it on only connected to the electricity did not work. always hear the sound of the fan but does not load the OS...
View 1 Replies View RelatedI love my new Inspiron 17R SE 7720. But I do seem to have some battery issues...
The battery simply never seems to charge to 100%. It charges to just 55-60% or so and never seems to get any higher. I've tried all the various power settings, including the various Dell special setting. Nothing seems to work.
It will be tomorrow before I can run the diagnostics I found in the support pages. But I'd like to make sure I'm not just missing something. Should it be charging when it's powered down but plugged in? I would think so, but still goes no higher than ~57%.
I've just reinstalled win7 Ultimate on my 7720 (09/2012) and have 2 problems: My BT mouse (Dicota BlueLight) stops working after a few minutes, and I have to remove it, and re-pair it several times before it will actually work. Each time I pair it I'm told it's working fine, and the driver is correct, but nothing happens. Ocassionally it will actually work, but only for 3-4 minutes before simply stopping again. The Bluetooth radio is showing as Generic Bluetooth Adapter in Device Manager.Also, in Device Manager I have a USB controller showing no Driver (Location: PCI bus 0, device 20, function 0) and I cannot find an appropriate solution anywhere.
View 1 Replies View RelatedWhen I turn my Dell Inspiron 7720 on, integrated webcam often does not work. Camera app in Windows 8 shows "there's a problem with a camera", other apps also show error messages or just a black screen.
After several resets the camera may start to work properly till the next reset. The camera is always shown in the Device Manager without errors and in the USBView I see that at least USB descriptors are correct. Moreover, after several disable/enable cycles in device manager the camera may start to work.
I've created two HDD partitions and installed Windows 7 Pro and Windows 8 Pro (both from original ISO files downloaded from MSDN). On clear Win 8 the camera shows the same problem, but on Win 7 it works properly.
There is no camera driver for Inspiron 7720 on the Dell web-site, thus I've used standard Microsoft driver on both Win 7 and Win 8.
I'm still not sure is it a hardware problem, because it is reproduced only with Windows 8. The computer was initially sold with Ubuntu, but Windows 8 is in the list of supported OS.
Camera IDs are: VID = 0C45 (Sonix), PID = 648D, REV = 2206.
