Driver Dell Latitude E5440

[Samantha Figueredo]

Ihave been dealing with the above named issue for a few weeks now and i don't know where the problem is. I have tried uninstalling and re-installing the drivers again but still doesn't work. I have tried updating from windows update but still nothing. I have tried updating from manufactures site but still nothing. I have a Dell Latitude e5440. My only solution is to either disable or uninstall the Intel graphics driver. But then my machine runs on Microsoft basic driver when that happens and my Nvidia gpu is not detected from there on. So i need my Intel to work in order for my Nvidia to work properly. What i'm i missing?? Please help. I'm running out of my mind here!!

After about two months of digging throughout the internet for a definitive remedy, I realized no solution was working for me. Then I went back to my computer to study the installation logs. It is from there that I found the problem with black screen upon installing intel hd graphics drivers. Apparently, installation always stopped due to the computer's power plan/policy. It happens that the intel graphics driver won't work with the default Balanced Power Plan, which seems to be the default when installing Windows 10 1803. Therefore, to correct the black screen, I entered into Safe Mode and reinstalled the problematic intel graphics driver, then went to the Control Panel > Hardware and Sound > Power Options. Under the Balanced (recommended) option, I selected Change plan settings > Change advanced power settings, then expanding the 'Intel (R) Graphics Settings > Intel (R) Graphics Power Plan', I set both On battery and Plugged in to "Maximum Performance". Then I restarted my computer and voila! It worked. No black screen again.

The switch for Bluetooth disappeared. I uninstalled it in the device manager and scanned for hardware changes, but it didn't reinstall. I manually reinstalled the drivers from intel's website and it still won't show up. Under services there are three Bluetooth related items all running on automatic. When I run the Bluetooth trouble shooter it says my computer doesn't have Bluetooth. My computer says everything is up to date and so are the drivers.

Thanks, in your case the restore may be what solved the problem. But still I gained great insight from your comment. You are the one who pointed me to the right direction(BIOS) where I found Bluetooth unchecked. I enabled it and installed latest drivers. Hurray! I now have Bluetooth.

Thanks so much for the update. My Bluetooth connection just disappeared.

What I did was to go F12 > BIOS > WIRELESS. Both my WLAN and Bluetooth is checked.

I just unchecked and checked again > APPLY.

I had noticed that my bios diagnostics said that no Bluetooth was installed. So I assumed my Bluetooth internal device must have had a hardware failure. But I was pleasantly surprised when this approach of using the restore old settings in bios fixed it.

This is supper. I did not know that Bluetooth can be enabled or disabled from Bios setup utility. I found the check box for Bluetooth unchecked. I ticked it and immediately the computer restarted, dell support assistant suggested driver update which I did and my Bluetooth worked immediately. Prior to this I had tried windows as well as dell troubleshooter which both showed I was running the lates drivers. Windows showed that Bluetooth is not available on this device while dell said the machine is out of warranty hence they cannot assist. Thanks man.
