Thank you, Artten. This issue has been plaguing me for a long time. I'd often go months without a black screen but lately I can't run more than a couple apps without it blacking out. I didn't have to check the Overheat Slowdown Override option and with these registry settings in place, the issue seems to have cleared up.
Changing the Graphics Card all depends on the factory installed Motherboard. It may not accept a 4GB or 8GB Graphics Card so you will have to call Dell Technical Support.
Another attempt to correct your black display is restarting and tapping the F8 key during the Splash Screen (the black screen) which is part of booting up.
You may have to do this a couple of times. Once you get the black display there will be several options.
Arrow down until the "Last Known Good" (Advanced) is highlighted and press enter.. This will reset the system when It was running normal.
The normal running for 24 hours and then the black screen, In my view only, indicates that your issue is the Graphics Card in normal as it will either work or not work.
These are only suggestions and you will receive other replies/suggestions that may fix your issues so I feel that it is a good idea to read ALL of them.
I had this issue for a long time and finally found some posts made where the users reported a heavy amount of dust build up inside the heat sink was causing high fan use and poor heat removal. The way that the heat sink is designed, the dust builds up on the inside of the radiator looking part. I broke the computer completely down, got to the area and sure enough, it was full of dust and could only be removed from the inside. (You can find some photos of this online if you look around.) No canned air solution on this! I also ordered a new heat sink and fan just to replace for good measure. Once I cleaned it out and replaced the heat sink and fan I have not had any problems. The only problem I am having now is the mouse freezes up when I run firefox. If anyone has a fix for this I'd love to hear it. Thanks and good luck.
Here you go...I've attached a zip file with the tool. I have had no problems since turning off the Overheat Shutdown option. One time a few months back, the problem came back after a Windows update, and I could not get it quit going black changing setting with the tool. So I restored my PC to an earlier restore point and everything started working again. No doubt that update was then reinstalled and neither it or further updates have not caused any problems.
You've found another user with the exact symptoms as you described. I even went through the same troubleshooting steps ruling out the display, wiped the Intel SSD then clean install, same issues with the CAP lock not responding, random screen blackout times with no response from O.S. Windows 10 Pro x64 bit and it gets even wierder as these issues are occuring on a replacement laptop for a duplicate M6500 that was having the SAME EXACT issues. Two M6500's, one a replacement for the other and having the same symptoms with no solution thus far. I second the need for help
After using the Nividia Powermiser Tool (attached in posting above) with the settings shown in currently attached JPG, I have had not reoccurrence of black screen problem.
I just bought a refurbed M6500 and was ready to send her back. This fix has saved that and now, I can move forward with my portable video/audio workstation!
I have just bought a M6500 with this same exact problem. I have an Nvidia Quadro FX 3800M. Neither searching nor the link posted works. This is a big problem for me since I plan on using this laptop for college. I'd hate to be out of the money I spent on this, having to remove the graphics card, and rely on Intel HD Graphics. Any help would be appreciated.

Hello,
I have the same problem with my dell M6500.
I tried to find Nvidia powermizer manager software in the internet but couldn't find it anywhere at all.
Do you have this software (Nvidia powermizer manager)?
If so, I 'd like to ask you to send it through e-mail.
Please.
I tried to click the link in your post but they didn't allow to download anything.
Regards.

There is a link above to the Nvidia PowerMiser Manager Tool. ( zip link above reads: M6500-NVIDEA-Tool for black screen.zip )
Use the tool to update setting as shown in jpg above... (jpg link above reads: nvidia powermizer settings.jpg
Both download links work for me. if you still have problems downloading, I'll email them to you.
My black screen problem has never returned.
