Hi,
I have a new Dell laptop and pretty much every time it goes to sleep it crashes with error code 0x9f
I have done all WIndows updates, driver updates and BIOS update, this seems to be a fairly common problem with Dell laptops
I have 5 minidump files I can upload somewhere if needed
I have analysed the dump file with Windbg and it gives the following output but I don't really know what to make from it
Thanks
DRIVER_POWER_STATE_FAILURE (9f)
A driver has failed to complete a power IRP within a specific time.
Arguments:
Arg1: 0000000000000005, The device failed to complete a directed power transition within the required
amount of time.
Arg2: ffff830fb8d60dd0, Physical Device Object of the stack
Arg3: ffff830fb8fb4010, The POP_FX_DEVICE object
Arg4: 0000000000000000, nt!TRIAGE_9F_DIRECTED_TRANSITION on Win11 SV2 and higher.

I own a new Dell laptop with the specified model and SKU.
All Windows updates, driver updates, and BIOS updates have been applied, which appears to be a typical issue for Dell devices.
Have you attempted reinstalling the operating system via a bootable USB, then installing it in offline mode, followed by installing all required drivers using the latest version through an elevated command? (Right click installer > Run as Administrator?)
I have five minidump files available for upload to a platform such as DropBox or similar services.

I haven't attempted a reinstall yet since I've only used the laptop for a few weeks.
Here are the minidumps.

Uninstall Norton Security, it came with the laptop and it's a mess. One of the dumps (112724-12718-01.dmp) fails due to a Norton driver (nllVmm.sys). The rest are power transition issues, probably caused by Norton too. In my opinion, it's just junk. Winders Defender and Windows Firewall are all you need.

It's my wife's laptop and it's not here at the moment, though I'm 99% sure I took out any Norton or McAfee software that came pre-installed. I'll double-check tomorrow.
I'll try using the Norton removal tool as well and let you know.

Certainly use the Norton Removal Tool. Simply uninstalling from Apps & Features isn’t sufficient. There are still multiple Norton drivers installed, so it won’t be fully removed. This is what’s causing the issue.

You don’t need third-party security software; Windows Firewall and Defender are more than adequate.

It turned out there was McAfee present upon installation, but it has been removed. She then installed Norton without my knowledge, and I have no idea why she did that.
I've tried the removal tools to check the outcome.
Thanks.

Norton and McAffe are both problematic, and combining them was disastrous. I’d remove both, but make sure to use the right tools instead of a standard uninstall.
