• Dell Inspiron 17R 5720 does not work with the charger. Charger is not recognized. No problem with charger.

  My Dell Inspiron 17R 5720 does not recognize charger. And unfortunately my warranty expired 2 months ago.
  It was plugged and work in the morning, but then in the afternoon I noticed he was running on battery only. It does not start without battery (charger just plugged).

  1 this is what I did to debug. Me and my brother, we bought the same computers Dell laptops at the same time a year and a bit ago. That's why a debugging purposes, it was good.
  I took my charger and plugged into his computer. And it works. Certainly not the charger problem I guess. And when I plug the charger my computer, green light is still on the charger. And I have the original charger provided with the laptop.

  2. now, laptop is running on battery only, so that means that this motherboard works. I think so.

  3. the next thing I did was charger disconnected and removed the battery from the laptop. Then I pushed and hold the "Power" button for 45 seconds to pay a royalty to the flea market. Charger plugged in but laptop will not start.

  4. then I booted the laptop on battery, went to the BIOS and check if the charger is recognized in the BIOS. No, it does not recognize charger. So, if this isn't a charger so what else can we?

  5 laptop has no strange smells so I don't know if something happened with the motherboard, but I guess that motherboard is ok because it works battery.

  6. I was thinking of updating the BIOS, but I can't do it, because it will be not be updated then the laptop runs on the battery, it needs to be plugged.

  Now I'm stuck. I don't know what I can do. I'm willing to spend a little more money on it to try to fix.

  If someone had such a problem in the past please let me know what you have done and if it fixed it.
  Or if anyone has any other ideas, I will be happy and appreciated the help.

  Hello and sorry for this late post. Just had this problem... If there is nothing wrong with the AC adapter, it's a software problem.

  Close the laptop... Unplug the AC adapter / CC... Remove the battery... Plug the power adapter... Start the laptop... Go to the control panel... Find and select the Device Manager... Batteries, left click... Uninstall Microsoft AC Adapter, uninstall Microsoft ACPI compatible with battery control method... In fact, uninstall all you can under the batteries, but that should be all there is. It will be re - install when starting... Stop cell phone... Remove the AC adapter / CC... Replace the battery... Plug the power adapter... Start the laptop... Now, everything should be good.

• New screen for Inspiron 17R 5720 - AUO-HD + FHD

  Hello

  I have a Dell Inspiron 17R 5720. I want to change the screen since the range of colors in this regard is bad in my opinion. The screen is an AUO B173RW01 V5 which is HD + I think it is a 40-pin connection.

  The AUO B173HW01 V4 would be compatible with my laptop? This screen is FHD, has the best range of colours by far and is also the 40 pin connection I think.

  More information on laptop:

  Mid-2012
  Win 7 64
  Intel Core i7
  Intel HD 4000.

  If a FHD is incompatible, there HD screens + who have a better range of color, brightness and contrast?

  If you need more info ask you please, I really want to fix soon!

  Thank you very much for your help!

  If this screen is known to be the one that was shipped with this model, it should work.  If this is not the case, see the link below for compatible screens

  >

  Also note that the wiring harness must be amended to increase the screen resolution.  Yes, the connector is the same - but the internal cable structure is different between the models of low and high resolution - if you try to use a FHD screen with HD cable, you won't see a complete picture.

• How do I know if my Inspiron 17R 5720 supports a backlit keyboard?

  There are several sites that sell backlit keyboards for the Inspiron 17R 5720, but they all have a warning that says something like this «...» If your laptop computer motherboard does not support the feature of backlit then the backlit function does not work.

  Well, how can I determine if my motherboard supports if the narrowing of my laptop down for 17R 5720 is not clear enough? Many subspecies of 17R 5720 (17R 5720-A, 17R 5720-B, 17R 5720-C)? How much more specific that I can determine if the kb works on the system?

  Impossible to get a straight answer from anywhere.

  It seems that the 5720 do not have the option of a backlit keyboard - the 7720 is the model that has made.

• Audio Inspiron 17R 5720 problem

  Hello

  I have an inspiron 17r laptop 5720 with which I am facing audio problems. Whenever I start it up, the audio does not work on the speakers and headphones. To resolve this problem, I reinstall the drivers by uninstalling the audio drivers in Device Manager, then restart the system.

  The audio works after the restart as long as I continue to use it all the time. If I stop audio playback for awhile and then try to play again, it does not work. I have to repeat the same procedure to uninstall the drivers + restart to get it working again.

  How can I solve this problem? Below are the drivers installed.

  Definition Hiigh CODEC IDT by IDT (6.10.0.6426)

  Audio device high definition from Microsoft (6.3.9600.16384)

  I tried dell support where it scans my system to determine if any driver download is necessary. All this turns out to be good. In addition, in the Device Manager, it says that the drivers are up to date. I am running windows 8.1 (upgrade of windows 8 from the "Bank") and is updated regularly!

  Help, please!

  Thank you.

  Hello. Go to the Device Manager and right-click on the IDT High Definition Audio Codec and choose to uninstall the driver. Check the box to delete the files. When you restart, you will use the native Windows audio driver (high definition Audio device). If the problem persists with the native driver then it might be a hardware problem.

  In order to exclude the hardware failure, perform a recovery of the system. If the problem immediately after a system recovery, so it's the hardware failure.

• Inspiron 17R cannot install windows on the new drive

  I have an Inspiron 17R SE 7720 with a dead 1 t HARD and the 32 GB SSD drive. The hard drive is a loss total and out of warranty, so I have to install Windows on a new hard drive.

  I don't have a recovery disk so I install Windows 8.1 since an original DVD I ordered from Microsoft, some time ago.

  My problem is that the laptop is not considered to be able to boot from the DVD. I get a message "No operation system Found."

  I changed the startup list in the BIOS to first have the DVD. I tried f12 to choose the DVD to start but nothing works. I checked the disc in another computer and it's good.

  I read something on the problems causing mSATA SSD and also on the Intel Rapid Storage is a problem.

  Please help if you can, I need the laptop for school.

  (Or fact) the DVD Player reads all other discs?

• Problems with Maxx Audio after Windows 10 'upgrade '.

  It seems I'm not the only one with this problem. I use a laptop computer Inspiron 17R 5737 provided with Windows 8.1. After upgrading to Windows 10, I noticed two things: 1. audio Dell, my Waves Maxx Audio 4 works, but miss me all my presets in the QE and I'm actually not able to set ALL the parameters at all. I called Dell 3 times now, for a total of 6 hours on the phone, where they had me not uninstall, then download and reinstall the Realtek audio driver. After you have downloaded and installed 2 times, the EQUALIZER presets are back, but I still cannot do anything else in the program. I noticed, after the first time, update the driver causing the error with Maxx Audio. So the second time I reinstalled it, I do NOT update the driver, but I am still unable to make any changes to the program. It's very frustrating because I record music and mix the final product with my laptop.

  The 2nd question I have to be carried out in another forum, as it has to do with my laptop to wake up do not sleep mode.

  The audio issue any help would be highly appreciated.

  I solved this problem first by downloading the latest audio drivers from Dell Realtek. For my XPS15/M3800 is Realtek ALC3661 Audio Codec version 6.0.1.7525, A00. It is a download of 325MB. After installing it and going through 1 or 2 reboots, my Dell Audio Sound Manager has been restored, but all presets MaxxAudio were missing. To resolve this problem, I opened the Manager of devices--> sound, video and game controllers, the user clicks Realtek High Definition Audio and selected update driver software. I chose automatically search for updates. Windows has found a version update 6.0.1.7628, installed, rebooted and then my presets have been restored.

• Portege M800-10V - creator of recovery after Windows 7 upgrade

  Hello

  first: how to reinstall the toshiba recovery tool creator to save it?

  2nd: the toshiba recovery partition is stay hide, but I don't know how or where is luncher it this function?

  Thank you

  Hello

  The creator of recovery disk can only be used on the pre-installed operating system, in your case of Windows Vista. After upgrading to Windows 7, you can t more use it.

  With other words disk recovery contains only Vista and you can create a new one with Windows 7. After using the recovery disk, you also have the Windows 7 upgrade disk.

• Switching mode inherited in UEFI BIOS after Windows 7 upgrade Win10

  I have an Inspiron 660. Last fall, I upgraded Win 7 to win 10/64.  I was watching the news system recently and I noticed that the BIOS was set to legacy.

  I see that UEFI is a step up from the BIOS.

  Is it safe to pass after the upgrade mode Legacy BIOS UEFI?

  If you have Win 7, it was probably installed as legacy (MBR).  The upgrade would have left it in this configuration.

  If you have a UEFI bios, you will need to do a clean install and select Install Media UEFI version.  Installation cannot convert the current drive TPG unless all the partitions have been deleted.

  So basically, if you don't want to remake your system, leave it in the configuration of legacy.

• Why can't I enter my upgrade key after Windows Anytime Upgrade on Vista?

  I bought the software update Window 7 Ultimate. I followed the instructions on the box:

  Click the Start button

  In the search box, type Windows Anytime Upgrade

  Click Windows Anytime Upgrade and clide enter an upgrade key.

  Yet, there is no link that says enter an upgrade key. There is only a link to the site Web microsoft talks Windows 7.

  I downloaded the Windows Upgrade Advisor. I did everyting that he told me to do. He checked that the computer was eligible for an upgrade (Toshiba Satellite running Vista).  I tried again with the Windows Anytime Upgrade again. There is still no link to enter the upgrade key.

  What should I do to get to the place to enter the upgrad key?

  Please note that there are no Windows Anytime Upgrade (WAU) for Windows Vista to Windows 7. There is only Windows Upgrade (WU) in which you need to buy a Windows 7 disc and upgrade of the key. You can refer to the link below for more information about upgrading Windows Vista to Windows 7.

• SOLVED! -Bluetooth not found after Windows 7 upgrade process - U350 only or other institutions?

  Man, I am hoping somone will be able to point me in the right direction...

  Anyway, has received Windows 7 Upgrade disks in the mail and decided to install them today because I had little time. Chose to 'upgrade' to the previous version of Vista (don't hate me for not doing a custom installation, 'clean'), and everything seemed fine, until I realized that my Bluetooth is not working (or even found in Device Manager).

  Run the separate drive Lenovo sent with the Win7 upgrade disk and made me worry more because the installation of driver told me that he could not find a Bluetooth device (which confirmed the same as Device Manager). Tried to download the drivers manually on the internet without success.

  Someone at - it ideas? The only possible 'factor' would be that I usually leave the Bluetooth in Vista, and when I ran the upgrade, Bluetooth was off I would have thought that Win7 would have seen the device anyway (regardless of the situation).

  Thanks to all in advance!

  Really should try to do a Forum search next time (instead of just google)...

  The answer to this was the Fn + F5 to ACTIVATE the Bluetooth module FIRST, before the system would see the in-camera. Once you actually turn, drivers can be installed according to normal... Thank GOD!

  CONGRATULATIONS to all the pioneers who have actually found this in the first place. Hope this was able to help some lost soul who has the same problem a few hours (and installs / uninstalls useless).

• Inspiron 17r - 5720 problems audio - static, hum, during playback of any audio and the sound of the speaker rear

  Hi, I got my laptop for less than a week and there are several problems with the audio. When no matter what audio is supposed to play, only a static noise comes from loudspeakers. This happens when the music plays, or when a sound system is supposed to play.

  Occasionally when I start the computer, the rear speaker makes a wooshing, a static sound (like a TV white noise) and will continue when I open programs.

  Hello. Unplug the power cable from the computer and listen on the batteries. If the audio improve, then you have a problem of material known with this model.

  The problem is documented in the FAQ Audio Choppy/jump. Look in the section for model Inspiron 7720 and 5720.

  Hello, Zohaib_R welcome on the portable Audio discussion Forum. Feel free to browse the FAQ portable Audio.

• Inspiron 17R 5720/Windows 8 Wifi

  I installed the drivers available in the order appropriate for Windows 8, and he does not even as an option on the new settings. FN/F2 toggle Bluetooth, and I get the same notification icon that I had on Win 7 Wifi turn power on and off. I guess we expect on Intel drivers?

  Hi guys,.

  I contacted the support technique dell via Twitter. They told me this driver. It worked for me. But I had to manually run the file setup.exe in the folder WLAN (see image below) because I came across a few compatibility issues with the driver for the Bluetooth device. My Bluetooth works fine so I don't bother. I went in this directory and run setup.exe: C:\dell\Drivers\P58H7\WLAN

  I hope this works for you guys. If this isn't the case, I recommend you contact dell via twitter support. The response was quick.

• Laptop HP - 15-r213ns: hotkeys (keys of wifi sound, brightness), does not work after windows update

  Hello

  I have a HP laptop - 15-r213ns (ENERGY STAR) with windows 8.1

  Last night, after an update of windows, the shortcut of the brightness (F2 and F3) volume (F7 and F8), wifi (F12) and keys all others have stopped working.  I can always change the brightness and volume using windows, but I can't do more using the keys.

  The function keys are working, as refresh F5 or F3 Browse. I noticed that before I had to press the FN key for this and now she does without the FN + Fx, so I guess that the update of windows must have changed something here.

  They used to work fine before the update. I reinstalled the display drivers (NVIDIA G-FORCE 820 - M) and looked for new drivers or update drivers using HP Support Assistant, but everything is up-to-date.

  I was looking for hot key factors in the page of HP drivers for my product but could not find any keyboard, drivers or software related shortcut keys.

  any suggestions?

  Thanks in advance,

  Marco

  Hi, Marco:

  The system of the event utility is supposed to get the Fn keys to work.

  Details:

  This package contains the HP System Event utility for the laptop models running a supported operating system. HP System Event Utility allows the special programming function keys.

  File name: sp70439.exe

  You can find this file in the Software - Solutions section of the driver for your model page.
