Dell Precision 7710 Backlit Keyboard Not Working

Q: Dell Precision 7710 Backlit Keyboard Not Working

I bought a computer from the Dell Outlet that was dead on arrival. I sent it to the repair depot and they put a new motherboard (5RY82 - Motherboard) and video card (YM9KW - Graphics Card) in it then sent it back to me. I powered it up and everything worked except for the backlit keyboard. I called and Dell Support sent me a replacement backlit keyboard that I swapped in and the replacement does not light up either. I called Dell Support again and they sent me another backlit keyboard that also did not work. I don't know what to do at this point and could really use some help from a Dell Tech.

I've got a Dell Precision 7710 with the Dell Precision Optimizer. It works great for when I'm using AutoCAD Civil 3D in setting up the laptop for optimization by turning off 2 cores and increasing the clock speed of the processor. 
Unfortunately I also do programming with Virtual Machines. When I'm in this mode I want all 4 cores to share the load instead of 2 cores. 
Is there a workflow available to go from one profile to no profile? Do I have to do a restart to switch between profiles? So if I'm doing CAD work and then switch over to programming do I have to turn off the AutoCAD profile to no profile and the restart the computer? I tried turning off the profiles and nothing changes for the cores. 
Is there a way to create my own profile? Or should I pick one like 3ds Max that would utilize more cores?  Or should I not use it since it won't meet my needs? 
Thanks.

My Dell Precision 7710 is 5 months old. One week ago the audio on my Windows 10 disappeared - the speaker icon got a red cross. Clicking on it I get the message that no audio speaker is connected. I reinstalled the drivers - tried three types: from Dell's website, Nvidia's and directly from Realtek - no result. Then reinstalled Windows with drive_C formatting: still no sound. I know that my laptop has a built-in Audio from Realtek. But in the Device Manager in the list of sound devices there is no such device: just "NVIDIA High Definition Audio" (in case of Nvidia's driver was installed) and "Audio Device High Definition Audio" (in case of Dell's standard driver) - both related to the HDMI output. No mentioning about Realtek Audio. It looks like Windows 10 doesn't recognize Realtek audio hardware anymore. I launched device test from Dell's Support website - the results said the system is alright, no problems. Thinking that probably this is a hardware issue I also launched the ePSA diagnostics (pressing F12 on the startup), but the test hasn't found any hardware problems. But when I clicked to audio test there (there was something about test beep) - there was no sound from the speaker.But Windows 10 still doesn't see any sound device (except that mentioning about HDMI). Here is 3 screenshots:https://imgur.com/a/ZgVYTWhat's the problem with it and how to fix it? Thank you. ...

A:Dell Precision 7710 - no Audio at all

Hi blamingas,
If there was no sound from the speaker when you ran the test in ePSA it would indicate a hardware failure.
If you send me a PM with your service tag and contact details I can look into options for you.

I own a M6800 that is not equipped with backlit keyboard and I was wondering if is possible to replace it with a backlit one. Are those two cross-compatible?
Also, I've been reading that people have problems setting the time for M6800 backlit kb (as there is no app for it) and they were using older version of Dell Enhancement Pack intended for M6700. If a replacement for my situation is technically possible, I would also appreciate a solution for controlling/configuring the light on the keyboard.

Hello all,
I just got in a new Precision 7710 system. I checked out the battery and it says 91 Wh, Standard, Li-ion Battery, Type MFKVP". 
However, the order I played had Lithium Polymer selected:
"451-BBUV | 6 Cell (91 Whr) Long Life Cycle Lithium Polymer battery"
Was I given the wrong battery or is it incorrectly labeled?

A:Dell Precision 7710 Batteries - Do I have Lithium Polymer?

No, you do not have the correct battery.
Unfortunately, Dell never made this battery or discontinued it before shipping (yet as of mid-April 2016 they are still offering it on new systems. Ugh.) The 91Whr Lithium-Ion battery (much cheaper) is their replacement equivalent.
You and I have been OVERCHARGED for a battery that they don't have. Call Dell and GET A REFUND.

I have a new Dell XPS 13 Linux edition (this one) and immediately installed Linux Mint 18 on it, wiping the Ubuntu 14.04 which was shipped with the it.
I am really confident with it, only the backlight for the keyboard is not working. I have a keyboard light symbol on my F10 key but when I press it, nothing happens. All other features and all other media controls/media keys/screen brightness keys work. When clicking the battery icon in the Linux Mint taskbar, I see 2 controls, one for the keyboard lights brightness and one for the screen brightness. When I drag those bars, only the screen brightness is working again.
I also see the settings in /sys/class/leds/dell\:\:kbd_backlight/ (I think that's the config folder for it). The brightness file in this directory contains "1", so as I understand this correctly, this should theoretically work.
As I noted before I immediately installed Linux Mint on it, so I can't say whether it worked before. And this is really the only thing which is not working on the laptop.
I have obviously checked that my ultrabook has backlights with the product number on its back.
Do you have some tips so I can get this to work? Thanks in advance!

Hi,
I purchased a Dell Precision 7710 laptop 2 months ago from Dell's website with the fingerprint touch sensor.  Afterwards, I installed Windows 10.
The laptop has been working fine until I installed the following update for ControlVault

Dell ControlVault2 Driver and Firmware
View details
File Name: Security_Driver_JP80V_WN64_4.4.28.187_A06.EXE

Importance: Recommended


Description: Update Package for Microsoft® Windows® 64-Bit. (27.78 MB)

Release Date: 10 Aug 2016

Version: 4.4.28.187 ,A06

Last Updated: 19 Aug 2016
The update appeared to succeed, but now I get a notification saying "ControlVault firmware upgrade in progress" EVERY REBOOT.  I tried uninstalling the ControlVault application, but that doesn't get rid of the popup. 

In the Event Manager, it shows an Event ID 2 for the source "USHUpgradeService" with a description of "CV firmware upgrade failed".

1)  How can I uninstall the ControlVault software?

2)  Is there a fix for a bad firmware install?  Or is the ControlVault hardware useless now?

I've had this laptop two weeks now and the backlit keyboard has just stopped working. According to Quickset, it is "on" and I've toggled between using the Ambient Light Sensor and not but to no avail.

When you start the notebook and before Windows loads does the keyboard light up?  You can also check in safemode, start the system while tapping F8 and choose safemode.  Log on to Windows, at any time in this process is the backlit on?  If not then there is likely a problem.  
If you aren't able to get the backlit on anymore no matter what you try please shoot me a private message.  On the Private message please include your name, address, phone number and the service tag of the notebook.  I will be happy to research possible service options.  If I can't help personally, I can certainly get you in contact with someone that can.

Just purchased a Precision Workstation 7520 from the Dell Outlet.  To my surprise, it came without a backlit keyboard.  Who would spend so much money on a premium laptop and not throw in a few more bucks for a backlit keyboard?  It really makes a big difference!
Anyway, I purchased a replacement backlit keyboard (383D7) and installed it.  The keyboard works fine, even the little light on Caps Lock key turns on when pressed.  But the backlighting does not work.
I tried the obvious fixes like double-checking that I connected the keyboard ribbon correctly.  And I also ensured that the contacts on the ribbon are clean.
According to the manual, there is supposed to be a Keyboard Illumination entry in the Bios that I can toggle on/off.  However, this entry does not appear in my Bios, which is the latest version 1.6.0.  I even upgraded the Bios (to the same version) just in case the upgrade process might detect the backlit keyboard and make the entry available, but no luck.
I suspect this might be a bug in the Bios.  This type of hardware control is purely a Bios function and has little to do with Windows.
To help me diagnose this, can anyone with a Precision 7510 or 7520 please tell me if you have a backlit keyboard that is actually lighting up?  If yes, which version of the Bios are you running?
Thanks in advance!

The machine came with 16GB in primary slots on bottom side.
Successfully upgraded them to 32GB.
Trouble with the top (secondary) slots underneath the keyboard.
First try (with memory installed) the machine was essentially "Dead" -- only the battery light alternated amber/white for a few seconds and the machine would power off.
Second try.  I used same brand as in bottom side.
The BIOS showed 64GB in all four slots.
HOWEVER, the machine would not boot up Windows 10 Pro.
After removing the memory and  putting back the battery, I noticed the keyboard electrical connectors to keyboard that are under the battery had worked loose. 
Don't know if they were already loose when I was trying the full 64GB installed.
Could this be the reason that the BIOS could see the memory, but the OS would not start?
Just asking before I go to the effort to try another time to use 64GB.  Having to deal with the keyboard each time is a real hassle.
OR, could there be another reason for the memory under the keyboard not functioning properly?
THANKS.

I am trying to do a clean install of Win 7 Pro on my Precision 7710 and every time I boot off of the DVD and click Install it goes a screen saying there are no drivers found for the device. I have tried switching to UMEI mode, RAID mode, Legacy on and off... no luck. What drivers am I missing exactly?

A:Cannot install Win 7 on Precision 7710

Hello!  In the BIOS make sure RAID is off and switched to AHCI, Legacy should be on, secure boot off.  Then when you hit the F key (forget which one) to access what to boot from, make sure you are using legacy DVD drive and not anything that would say UEFI.  As long as you are not using RAID or via some USB 3 external drive you should be fine.

Hi, 
I'm custom configuring a Precision 7710 system and trying to pick a 2nd SSD.  
The boot drive will be the "512GB M.2 PCIe NVMe High Performance Class 50 Solid State."   I believe it's connected directly to the PCIe bus buss via an M.2 connector.  
For the second drive I'm considering the "512GB M.2 PCIe NVMe High Performance Class 50 Solid State Drive with Interposer."   However, I looked up Interposer and it appears to be a SATA adapter. So, does this mean the 2nd drive will be running on the SATA bus?  If so, this high performance PCIe SSD will not be able to live up to it's full potential due to the SATA bottleneck, right?   I would be better off just getting a cheaper SATA drive, no?

Hi!
Our corporation are running several lines of computers from Dell where as the Precision 7710 (soon to be 7720) is currently the "top of the line" laptop computer available for our employees.
Some of us are finding the Quadro cards installed limiting for certain tasks and I am currently researching the possibilities connecting an external egpu unit to the P7710 through the Thunderbolt 3 port.
The setup I have is, as mentioned, a P7710 connected to an Asus Rog XG Station 2 holding an Asus Strix Geforce GTX 1080 TI inside. It's not working. I spent the entire day reading forums and reddits, flashing bios and updating all drivers possible. I've also been tweaking and adjusting settings inside the BIOS ot get it working.
As far as I can tell the Thunderbolt firmware currently available to the P7710 is not supporting external GPUs. PD Firmware version is currently 16.00. Thunderbolt do recognize the external unit by name though.
Any help getting it working or notification on implementation progress is really appreciated!
Thank you.
Best regards.

I have a new 7710 that came with a 256GB NVMe SSD.  I have upgraded it to a Samsung 950 Pro 512.  I am using Windows 10 UEFI.
I have a question on the bios setting.  Should it be AHCI or RAID.  The machine came default with RAID On and came with Win 10 Pro pre-installed.
Currently I switched it to ACHI, used the MS Download and installed Win 10 Pro.  Once in windows, I installed all the dell drivers and also the Samsung NVMe driver.
I have read on different forums that the bios setting should be RAID, but also read it should be AHCI. 
Question:  Which should it be.  Is one better than the other?  
Or is it just that if in AHCI, it will use the MS NVMe Driver (or Samsung NVMe Driver) and if in RAID, it will use the Intel IRST drivers?
I assume if AHCI like I have it, then I can use the Samsung NVMe Driver.  I have read if not in AHCI, the Samsung NVMe Driver will not install.  
If I switch to RAID, then I would need to use the Intel Rapid Storage Tech (IRST) Driver and not the samsung driver (I read samsung driver will not install if AHCI).
So I am confused if one is better than the other (AHCI or Raid).
FYI, I have been using for around 10 days and no BSOD due to the PCIe NVMe drive.

A:Precision 7710 and Samsung NVMe 950 Pro

I own a Precision 7510 and am in the same situation. I did exactly the same except that I left the BIOS setting to Raid ON. When in Raid ON the Samsung Magician can only do the following:

Disk drive information for all installed disks. Particularly with the NVMe drive S.M.A.R.T. is not functioning even though it should be. All other drives display S.M.A.R.T. correctly.
Performance Benchmark. Only this function is selectable. All other functions are not available. Probably because the Intel Rapid Storage Techonlogy driver is loaded and not the Samsung NVMe

From performance view it seems pretty fast. Today I am going to change the BIOS setting to AHCI and I will share my results.

All right, so my company has a try-buy 7710 that we're thinking of making our high end standard. This unit has 2x M.2 PCIe drives in it.

I have a Precision 7710 that the adapter does not power up on the newer Boeing 777's.  I've been told that the 240w adapter is the issue.  The plane power limit is apparently 95w?  Anyone know if a lesser wattage adapter would work with the Precision 7710?  Doesn't need to charge the battery, only needs to power the laptop so I can work longer than 2-3 hours on my long 13 hour flights.

You need a more portable system than this one if you plan to use it on long flights - there's no way 95W will power a Precision 7710.

Hello together,
hope some one has an idea.
We have an Precision 7710 which often, e.g. after returning back to the docking station, doesn't recognize the USB devices like mouse, keyboard and wireless headset anymore. These are connected to the docking station.
In the device manager are then a lot of unrecognized devices also.
We changed already the docking-station, no effect.
We tried to uninstall / install USB device drivers.
We made BIOS update.
Dell support changed the main board, that had no effect either.
The device got reimaged, then it worked for two weeks.
Now the problem reappeared. The user has no administrative rights, no installations have been done in the mean time. He only worked with the laptop, e.g. connected USB sticks, a Nokia phone and a 3D mouse. 
I got it running again by deleting the unknow devices in device manager, then docking again. But after some minutes and undocking / docking the problem appeared again.
We have the same Laptop with same installations at other places with no problems.
Dell hotline says now I have to reimage again, it is probably a software error.
Is it really possible that connecting some USB devices can break all USB ports at the docking station?
Probably we will reimage one more time and take care then which devices we will connect. 
But I don't really know what to do then. I fear the problem will appear at random again.
Windows 10 64-bit is used.

I decided to upgrade my Dell Precision 7710 (service tag: <Service tag removed>) from non-ECC memory to ECC memory. The laptop was originally configured with 8Gb of non-ECC RAM (2x4GB 2133MHz Hynix p/n HMA451S6AFR8N-TF). After replacing the original memory with ECC(2x16GB 2400MHz Crucial CT16G4TFD824A.18FA1 p/n 18ASF2G72HZ-2G3A1 ) the laptop does not boot. Status LED blinks 2 times amber and 5 times white. The cycle repeats few times and the computer powers off.
I'm using only primary memory banks (both of them are working fine with original sticks) and the newest available BIOS – 1.9.5 .
I've tested several configurations and the only one that works is mixing an old 2133MHz non-ECC stick with a new 2400Mhz ECC stick. This suggests that BIOS is not able to handle scenario when only 2400MHz memory is installed.
Are there any chances that this will be fixed by BIOS update?

Hey guys, I just had a Dell Inspiron 15 5559 delivered to me yesterday and I noticed there wasn't a backlit keyboard installed. At first, I thought it was just off, but after looking around this site and doing some research to first make sure I wasn't just not able to turn it on, I've arrived to this conclusion. 
I've tried doing Fn + F10. I've tried Ctrl + F10. I've tried going to Mobility Center and changing multimedia/function key.I also have all my drivers updated and made completely sure everything was updated in case it was just a software issue. I also updated BIOS and went there and checked if I could change keyboard settings there; no luck.
The thing is, my laptop is the touch model and to the extent of my knowledge, all touch models are equipped with a backlit keyboard. So what's going on...? Do I have to pay out another $50 for a backlit keyboard?

I recently just purchased a Dell Inspiron Gaming 7567 and I mistakenly purchased it without a back lit keyboard. Returning the laptop is currently not an option. I was wondering, is it possible for me to replace the none back-lit keyboard with the back lit equivalent for the device and for it to be full functional (i.e. a fully working keyboard + toggle-able back lit keys), or will replacing the part just yield me another keyboard without a back lighting. Minor inconvenience, however I would be extremely happy if I could change that on my laptop. I hoping someone has the answer.

Hello Everyone!I bought an open box Dell Latitude E5470 today at a very cheap price. Unfortunately this laptop had a non backlit keyboard and a TN (1600 x 900) panel but it had the much needed 6300HQ, so I went ahead and bought it thinking that I can always buy a backlit keyboard later from aliexpress. I looked at aliexpress again today and noticed something I had overlooked before purchasing the laptop and that is that all backlit keyboards available for E5470 have a different shape thanks to the two stupid top mouse buttons that are not present in my variant of E5470. I now have to find a new top panel with frame that has the cutout for those two extra mouse buttons. This is a nasty situation for me as I am not even sure if the required top panel will be compatible with my variant of E5470. Any advise on what I should do?

I recently purchase a Dell Laptop 15 3558, awesome deal touchscreen and many additions. Only thing it didnt have was a backlit keyboard, so I went and purchased a (refundable) non-Dell backlit keyboard on Amazon.
I know a backlit keyboard has 2 connections, one for data and one for the light. When I opened up my laptop the light connector had something plugged in (not sure what). I went ahead and disconnected it and plugged in my new non-dell backlit keyboard...here is what happened.
1- Key board lit up and worked.
2- Back lIght never shuts off, even when you shut down its always lit. (The Windows Mobility Center doesnt even have a keyboard light feature.)
3- Laptop will not restart unless I unplug and replug the laptop in again.
Any ideas whats going on ?
Lastly, Does Dell make a backlit keyboard that would be compatible?

A:Purchased Non-Dell Backlit Keyboard - having issues

Hi MOEMAYA,
This system model is not designed to support a backlit keyboard and hence there are no backlit on /off toggle function keys as seen on other models - see the specifications here - http://dell.to/2gryrMy
Does the backlit stay on when the system is powered off and the power adapter disconnected?
Update the BIOS - http://dell.to/2h6A06p - restart the system and check.
If the issue is not resolved, then I would suspect an issue with the keyboard installed. 
In that case you would need to reinstall the original Dell OEM keyboard on the machine.
Also, please click my DELL-username and write me a private conversation with the service tag and your Name for case records.

I received a brand new Precision 7710 and the first thing I do is complete all Windows updates and do any driver updates that need to be done.
Here are the laptop specs:
Computer:  Mobile Precision 7710BIOS Version:  1.3.12OS Version:  Microsoft Windows 7 Professional 64 bitManufacturer: Intel(R) Xeon(R) CPU E3-1535M v5 @ 2.90GHzClock Speed: 2.9GhzL2 Cache Size: 102417.3" UltraSharp UHD IGZO(3840 x2160) Wide View Anti-Glare LE D-backlit6 Cell (91 Whr) Long Life Cycl e Lithium Polymer battery240W AC Adapter64GB (4x16G) 2133MHz DDR4 MemoryAMD FirePro W5170M, 2GB GDDR51TB 2.5 inch SATA Solid State Drive,MPWSWin 7 Pro,SP1,No Media,64bit,O pti,ENGIntel Dual Band Wireless 8260 (802.11ac) W/ BluetoothIntel Xeon E3-1535M with Smart Card and Thunderbolt 3

I received this laptop on Monday March 21, 2016, saw that there were approx 4 or 5 driver updates on dell.com/support.
I chose to download all updates to the desktop and update from there as I always do.
I saved the bios update for the next day March 22, 2016 as I wanted to be in my office to do this update.  I am well aware you can easily turn your laptop into a brick if the update goes south.
I come in and begin the update via the Precision_7X10_148.exe on the desktop I had downloaded from dell.co... Read more

A:Mobile Precision 7710 BIOS update 1.4.8 failure

Wow! You saved me.
I had the exact same issue with the 7710 and the 1.4.8 BIOS.  Motherboard replacement was scheduled for tomorrow.  
I did a search found your post and now my machine is back in business.  No replacement necessary.
Thank you for troubleshooting this and posting the solution.
This is what the Internet is all about.

Precision 7710 How many m.2 SSDs can install into 2.5" drive bay
What parts are needed to achieve maximum?

A:Precision 7710 How many m.2 SSDs can install into 2.5" drive bay

The 2.5" drive bay still only has a single SATA connector available on the motherboard, so even though multiple M.2 SSDs would physically fit in the space of a 2.5" drive bay, you wouldn't have a way to connect them all. Even if you only wanted one, I'm not sure there's an M.2 to SATA adapter.  I know there are mSATA to SATA, but that's a different physical connector.  Also note that even if there WERE an M.2 to SATA adapter,  you would need to ensure that your M.2 SSD used the SATA protocol, not NVMe/PCIe, since that would not be able to run over SATA (and even if it could, its performance would suffer significantly by doing so).

Only 3 lights on backlit keyboard are working: Volume on/off, wifi on/off, and backlighting button on/off. Is there a way to troubleshoot software and hardware issues related to this problem? Or does this require replacing the keyboard all together. The keyboard is in mint condition so very frustrating

After installing an ssd recently, the backlighting on my keyboard no longer works. Every other button on the keyboard works normally, including the other built in function keys like mute, brightness, etc. I might have messed up some connection, but I didn't take the keyboard off at all to install the ssd, which was installed without issue itself. Another thought is that it might be a driver, since its a fresh drive and windows install. I don't really know what to look for though, so any thoughts you might have to help would be appreciated.

I just received my thinkpad P71 yesterday and I'm using it right now. Immediately off the bat, I removed the Hard drive in favor of a far better one. I'm curious to know does the keyboard require any special drivers for the backlit keyboard to work? I assume that it works similiarly to the W541 Backlit keyboard in which I hit Fn + Space Bar, it should work right? Well, currently it is not working. Keep in mind that this is on a Fresh install of Windows, does it need drivers to work? Thanks!

Hello everybody, just purchased a Z50-70 and am pleased so far.However, the A**zon product specifications stated it would have a backlit keyboard (bought the 59424714). Up to now I have not been able to switch it on (Fn+space doesn't work) and/ or find any settings for it. Can anybody help? Thanks in advance!

Make sure all drivers are installed and up to date, also check bios settings just to double check everything is ok in there.

Hi Folks,
   I have a pDell Precision 7710 with 16G RAM and the ATI graphics card.  Whenever I do a lot of writing to either a USB 2 storage device or a SDHC card, the machine locks up with blinking caps lock light after a few gigabytes have been transferred.

I'm running Linux with kernel 4.13.0-rc1 (but the problem has existed on all the kernels I've tested back to 3.10), and have the latest BIOS.

To reproduce the problem, do
  dd if=/dev/zero of=//mmcblk0 ***=1M
with a 4Gbyte or bigger SD card in the slot, otr do a similar tansfer to a USB stick.

Hello..

I have the S50-B-15P model with Windows 10 installed. I never checked if the backlit keyboard worked on Windows 8.1, as soon as I got it I upgraded to Windows 10.

I have installed all the drivers from the Toshiba Windows 10 upgrade page however as before the keyboard works just not backlit!
I opened the eco utility software and checked for the keyboard backlit settings under eco mode however it does not exist and no setting exists in the BIOS either.The keyboard does have the symbol to enable the backlit function on the Z key however pressing FN + Z does nothing.

Does anybody have any ideas on how to fix this? Does the keyboard even have this function or is it faulty?

Thanks, Craig

No drivers are needed.  If you have a backlit keybiard and it doesn't light, you have a defective keyboard.

I have recently replaced my laptop's bezel. Since then backlit is not working even though the settings are correct. Could this issue be due to bezel replacement. If yes, please suggest how to resolve it

A:backlit keyboard not working- XPS 15 L502

I assume that removed both the keyboard and palm rest first to remove the LCD assembly and finally the LCD bezel. I would go back and check the keyboard and make sure that both the keyboard data and back lite cables are connected correctly. The manual doesn't show a back lit keyboard, but on back lit keyboards there are two cables that will need to be connected.

I just received my new XPS 13 9350 and the backlit keyboard never worked.. the only light i can see is from the caps lock...
I've no idea whether this is a hardware problem or just some driver problem...
I've tried the BIOS setting but nothing changed. And the Windows Mobility Center didn't show anything about keyboard backlight..

Hi,
Thank you for writing to us! You can use the F6 key combination to enable or disable backlight.

Hoping this helps!
