My Dell Precision 5510 Laptop Does Not Go To Sleep Sometimes

This question has been answered by kstoilov

Hello Everyone,

I am having this problem with my Dell Precision 5510 laptop where sometimes the machine would not go to sleep if I close my machine's lid. I am actually running Arch Linux instead of the official Dell Ubuntu distro.

I know that sleeping normally does work when closing the lid since most of the time, my machine would feel cold when I take it out of my backpack. But this is starting to become more of a problem recently where my machine would be burning hot when I take it out of my backpack. I am worried that my laptop will not last for long if this keeps happening...

I am not sure if this is an improper configuration of Arch Linux or a hardware issue. Has anyone else experienced these problems?

Thomas A.

  • This is probably caused by the following ACPI error, which is due to Dell's broken BIOS. It is a known issue it seems:
