Dell XPS 13 9310 sleep mode issues

" have opened a few browser tabs and place it in sleep mode by closing the lid or pressing the power button"

-----------------------------------

You are spiking up memory (ram) on the computer by having browser tabs open in sleep mode. This is why Diagnostic keep running a scan. You could set Sleep to a few hours or Never in Sleep settings while working on a word/power point document. Then again, you would still have to keep an eye on Memory and CPU in Task Manager. If Memory is around 80% - 100% in Task Manager then surely computer will shut down or power off.

I suggest creating a image of windows 10 or back up your files, photos, music, documents and other important stuff to a Cloud or to a external drive. There are many backup software that you could use, two that are popular within the computer world:

Macrium Software | It’s our business to protect your data

Thanks for the suggestion. However, this did not happen in older Dell XPS 13 2015. Essentially you cannot put the laptop in sleep mode  and continue working on later. It's either keep it on for the whole time or shutdown completely without using the sleep mode?

I'm having the same problem! I'll leave the machine, go do something, and when I wake it back up, it reboots, tells me the OS crashed with a memory error, runs memory diagnostics, finds no problems, and boots back into Windows fine.

I suspect it might be a problem with the Connected Standby mode, based on a cursory Google search.

What LSUFAN51 said is bogus. If you open too many browser tabs for how much RAM you have, the browser will kill some tabs or the OS will kill the browser -- this is a situation they're totally equipped to handle. The error we're getting indicates a hardware, firmware, or operating system bug.

I'm having the same issue with my 9310. Seems like a driver or BIOS issue, one that I hope that they can resolve quickly!

Dell support wanted me to reinstall a clean copy of windows. I backed up everything and created a windows installation on a USB drive. BIOS wouldn't detect the hard disk when trying to reinstalling windows using USB drive. So ended up doing a soft reinstall which wouldn't delete all your saved files and programs. I haven't had sleep mode issues since then. It maybe been an issue with Windows copy which came preinstalled from Dell.

Fingers crossed and hope it doesn't happen again.

I've got the exact same issue, ever since the latest BIOS update when you tell the laptop to sleep the display turns off but the laptop continues running as normal.

@Fil Sapia, that's not the same issue, and it's (sadly) not actually considered an issue; that's just how Modern Standby works. The screen turns off and hardware goes into lower power modes as feasible, but apps can still run and sync data (like a phone).

Your problem should be a system setting problem. If it appears recently, it is recommended to reinstall the system.

@lan1991008, your comment is unhelpfully vague (which setting?), wasteful (reinstall without trying anything first?), and just plain wrong: some of us have already tried reinstalling Windows and the problem has persisted.

Like others, I have seen this in a brand new 9310.

I did a few things which may or may not have made a difference (it hasn't happened recently):

• Firmware updated to 1.1.4 (Dell support page)
• I upgraded the Intel Graphics driver here (27.20.100.9079): https://downloadcenter.intel.com/download/30079/Intel-Graphics-Windows-10-DCH-Drivers (recommend the .zip version of the install package)
• I also updated several other Intel drivers but I can't remember exactly which.

We should see if there is some common thread to our issue:

• Intel i7-1185G7
• 16GB RAM
• 512GB NVMe (Kioxia) Drive
• Windows 10 Home 20H2

NOTE: I haven't seen the full reboot into recovery mode in the last day or 2, but I do notice the "USB connect / disconnect" sound coming from the computer every now and then when I leave it alone.

@iamscott Sure, here you go:

For me, updating the firmware to 1.1.4 alone did not fix the issue. Throughout the process I've been checking Windows Update and Dell Update frequently, but I don't recall any particular updates fixing the issue.

I've got the i5, 16 GB RAM, 1 TB NVMe (Micron), and it's reproduced with the most recent Windows 10 Home and Pro. My gut says it's going to be a BIOS problem that's common to all configurations, though.

(also having this problem)

The solution for me was to switch from "sleep" to "hibernate" for the case close action, and other power management settings to avoid sleep mode. I too hope Dell fixes this problem.
