Dell Latitude E6420 :: Three Monitor Setup (VGA And DVI)
Jun 19, 2012
I am trying to set up my laptop to use two (2) external monitors (both Dell monitors). I am using a Dell Latitude E6420 laptop that has an external VGA connection as well as an HDMI connection. I can currently use the laptop LCD screen as one display and an external monitor (either VGA or DVI) as the second, or I can use both external (VGA and DVI) as my extended output. But I am unable to get it to work with all three. Is this a hardward limitation? or Setup limitation? Do I need third party software to accomplish that?
The laptop is running Windows 7 Enterprise 64 bit.

I have a Latitude E6420, and i can't for the life of me get it to work. There is absolutely no life, and the battery and power lights don't light up with the ac adapter connected. I've tried taking out the battery and connecting the ac, no change. Won't work.

I have a Latitude E6420 that came without a Bluetooth card. Is it possible to add the Dell TrueMobile 375 Bluetooth module to this machine? I looked in the Service Manual for the 6420 but it did not show where the Bluetooh moduel cable the plugged into the motherboard. In fact, I opened the case and found the slot where the Bluetooth module would be mounted but did not see a place to plug in the cable.

I always put my laptop on standby and turn it off only when required. Today 4 hours after I left it on standby, I could wake him up from standby but could not see anything on screen which worked and all operating system sounds could be heard, hard drive worked as well. I tried powering it off and on, entering BIOS but I still could not see display. Here's a link to YouTube video that portrays what I see:
cs_setInnerHtml('video_b18ffb1a-cd3e-41db-bbec-cd6ba4b8104e','');
I later saw information here on how to access ePSA testing environment so I followed the steps: removed battery, plugged off power supply, pressed Power Button for 1 minute to drain power, held Fn key and powered laptop on until I heard funny sounds. This was ePSA probably but I still could not see anything on screen:
cs_setInnerHtml('video_bc3d9966-f72d-4bdc-853b-07df0bd78756','');
If I am not mistaken, my laptop was running on dedicated nVidia graphics card. What should I do now? Luckily I have customer on-site warranty still valid, but I am looking for a faster way to solve problem. Who knows, but it may be a mere problem of cable got lose which is in my abilities to fix.

I recently came to the same fate, Recently had my battery replaced by Dell which was wonderful n the mess up part is that I cannot get it charged on my Latitude E6420.
My flashing problem started when I had a power failure in my area while i had my note book on charge. I cant do anything without having to keep my notebook on charge. i doesnt start up without it being plugged in now n it doesnt even charge my new replacement battery.

I have the charger from here brought as a replacement for the original one, but when I plug it - the laptop works, but the battery it's not charging. The battery is 6-7 months old, was pretty good - lasts for more than an hour and a half, but it's not charging now.I have tried to enter the bios and stay there for about 2 hours but the battery does not charge..Or the charger it's not the good one?

I am trying to install a Dell TrueMobile 375 Bluetooth module in my Latitude E6420. I have read the instructions in the E6420 Service Manual but it is not obvious where the other end of the cable on the 375 Bluetooth module plugs into the motherboard. The images provided in the Service Manual are of no luck, as they only show where the module goes, not where the cable on the module plugs into a corresponding socket.

I recently had to reinstall my Latitude E6420 with Windows 7.
Afterwards, Audio and Video (having Spotify+a few Office apps running) start to lag.
I tried reinstalling the Machine again without success. I tried all driveres suggested on the Dell supportpage and I asked google which told me "Turn off eSATA and SpeedStep" [URL] .... which hadnt any success either.

The above fails with an error "check for updates failed" in the gui.
Sometimes it determines the list of updates to get, but then fails to download those updates, sitting on the download screen and doing nothing.
Files are created C:UsersadrianAppDataLocalDellClientSystemUpdate emp but they never exceed 11.7MB.

when I dock my in my E-port docking station, my CPU usage will shoot up to 100%, and it may come down periodically to the 80s or 90s, which makes my laptop virtually unusable for anything. I tried a different power cord but it made no difference. Undocked, it works just fine, so it's obvious it's something wrong with the docking station.

I purchased a Latitude D505 from a police auction and the BIOS setup is locked by password. It will not allow me change setups, such as system time.
Under system security it shows Primary Password unabled, Admin Password Enabled, Configure Setup Disabled and Configure Password enabled.
I need to clear these in order to setup new HDD and operating system.
If needed the present sys number is #6M81L51-595B

I have a new Dell Latitude. When I first started working with it, a box asked if I wanted the screen to adjust to ambient light. Being new at this, I said yes. Now, I have a monitor which is constantly getting brighter and dimmer even within a few seconds.

I have a Dell Latitude E6820 and have just connected a new Dell E-Port Plus II Docking station. Plugged in to the docking station are two monitors, one plugged into DVI Connector 1 and the other plugged into DVI Connector 2. The laptop is running Windows 7 64 bit.
Try as I might, I can not get the system to recognise the second monitor. I have tried the following to get this to work.
- Enabled Optimus (I think that is what it was called in the BIOS) - When I enabled this, neither of the monitors would work via the docking station
- Disabled Optimus - One monitor works
- Attempted to detect the other monitor via Control Panel > Display > Adjust Resolution (monitor not detected)
- Swapped monitors and cables in case it was a cable or monitor issue. All Cables and Monitors have been verified as working as expected.
- Attempted to connect one monitor via VGA cable. Only one monitor was detected

With this configuration if I have the 2 monitors running I can't get any picture on the laptop screen. I wanted to be able to use all 3 screens at the same time is this even possible, how to have all 3 screen working at the same time.

I'm looking for a computer set up. After some research, I'm leaning towards a Latitude E4300 (with decent specs) and the above mentioned display. The idea is to have a powerful, yet portable notebook for taking to class and mobile study sessions, then having the display function as almost a desktop computer. Has anyone had a similar set up before?

I recently just purchased and received a fancy Dell e6400 from one of the many dell deals. My eyes are light sensitive from looking at many computer screens over the years and due to this I avoid LCD screens and much prefer flat CRT monitors. My goal is to use the e6400 as my workstation computer while using the VGA out to power my 19in Sony CRT .....

i dissasembled my presario cq60 and when i put it together the monitor won't activate.
i tried using an external monitor and the monitor refused to turn on from standby, a safety feature of the monitor. the small card in the underneath with 2 wires leading 2 the monitor, (i assume that is the laptop version of a graphics card) is fine, inserted properly, and i had a slight issue with the plugs fitting, but that was soon resolved.

I have an HP DV 6000T. I just bought a HP Elite M9510f Desktop from HP.com, and I don't have a monitor yet, so I am trying to connect my Desktop VGA to my Laptop VGA in and use my DV6000T as a monitor.
I also have a Sharp TV which I tried using as a monitor but the thing keeps flashing the Power and OPC lights and won't let me see anything.
Anyway I can make my Laptop monitor work with my desktop for the time being?

Is there a way to get 2.1 audio instead of just stereo so I can have control to my subwoofer?
I can only choose stereo, quadraphonic, and 5.1 surround under speaker setup. Is the bass boost the only way I can control my subwoofer on the laptop?
I just have on board audio with sigmatel HD audio software. It will let me change my 2 audio and 1 mic port to all 3 audio ports for front, center, and rear.

I have recently been completely unable to access the set-up area of my bios on my Dell XPS 17 L702x laptop. On booting, i keep pressing the F2 key which seems to be registered by the BIOS as the text that says 'Set-Up' lights up. However, instead of entering the setup, the BIOS simply continues booting my operating system. Even if I remove all of the hard drive's, I cannot enter the set up and the BIOS boots to the PXE Setup.
I have tried reflashing the BIOS but nothing changes, the set-up is still inaccessible. I can't even change the boot order using the F12 key.
I really need access to my BIOS and I am all out of options.

Ever since I saw newer systems being offered with Dual SSD drives in RAID for 128GB of SSD storage I've been wondering if I can do that with my XPS m1710.
My 100GB drive is just too small. I've been looking at replacing it with the Hitachi 200GB 7200 RPM drive, but I thought I'd look at the SSD option as well.
