XPS 15 9750 sleep mode and freezing problems

I bought this computer for animation purposes and since the first week: 1) system freezes randomly regardless the task it's performing. 2) It never wakes up from sleeping mode, keyboard light tuns on when pressing but nothing happens, I have to reboot it all the time. 3) Sometimes, when login screen displays and you re-log, all tasks and windows that were open are now ended and closed. 4) There are blue screen errors also. 5) And last week after a blue screen I got a "hard drive not installed" message. What's going on?! I had to travel as soon as I got it, and I'm working on location with someone else's computer right now because this one doesn't work well. I'm very disappointed.

Re: XPS 15 9750 sleep mode and freezing problems


Thank you for your message. I apologize for the inconvenience caused.


Did this issue start after any recent Windows or driver update?


Is the system connected to a dock or an external monitor?


Run a hardware diagnostic by following the video on this link & check if there is an error.


What is the BIOS version installed?


What is the bluescreen error message you get?


For my reference, please click on the message tab next to your avatar– click “New Message” & search for my Dell username (Sreejith R) & send a private message with the service tag, registered name & email address.
