Dell Latitude 7420's crashing

I'd recommend running the preboot diagnostic on the units. If this test is also freezing or if the units freeze while idle in the menu or in the BIOS, then you're likely looking at hardware failures. Seeing as the RAM is integrated on the motherboard, that will limit hardware you can test to really just the SSD. 

1. Shutdown the unit
2. Hold down the Fn key and the power button together
3. The quick test should automatically start
4. Make note of any errors or freezing and contact Support

Since you mentioned freezing when plugging in a charger, does physically moving the unit cause it to freeze up? If its freezing when being picked up or on movement, that too will typically point to the motherboard. 

Hi Daniel,

Thanks for your response. 

I'm anticipating this to be a software issue, as it's extremely unlikely that 15 of the same make/model all have a similar hardware fault at the same time. The devices don't seem to freeze as a response to movement.

It's worth noting that these devices all worked perfectly fine a month ago, which makes me think that a specific update has caused these issues.

Kind regards,

Ben

If you have one of the systems you can use as a test, remove (uninstall) any updates that have been installed at or since the time the issue began.  Does that solve the problem?  This includes any firmware updates, Windows or driver updates you know where either manually or automatically installed.  If you have system protection turned on, you can also try reverting to a restore point before the issue began.

@Zeal_LG 

1) use DELL Command | Update to grab the lastst drivers for your machines
2) USB-C Dock: make sure, you got the latest firmware for the docks

3) if you on W11, make sure to get the release 25H2 26200.8037

We're also having this with 183x 7420's. Seems to be a mix of either Windows Update, Intel Chipset Driver or BIOS... Disabling modern standby/sleep has helped to some degree but it's not perfect.

We are also encountering this with multiple 7420s.

We performed detailed analysis of the system state at the time of the incidents, and have narrowed down the issue to an inconsistent deadlock condition inside of the Intel Graphics kernel-mode driver when toggling power to the internal display that crashes csrss.exe.

We have an open case with Dell Support. Potential workarounds for the time being that we have not tested could be falling back to the Microsoft Basic Display Adapter and/or disabling the lid switch in BIOS and disabling sleep and screen off in Windows. Downgrading the Intel Graphics driver should also be tested, but it's difficult to work around Windows Update and DCU attempting to automatically reinstall it.

This has been not good for our organization.

We had to replace several with Lenovo laptops to avoid the issue.

Driver & BIOS updates having zero effect.

Thanks all for the recent posts!

Our organization has encountered exactly the same issue with 4 (reported by now) Latitude 7320 laptops. BIOS + drivers via Dell Command | Update are up to date.

No solution or fix found so far.

Hi all, 

Can you try updating the GPU driver with this version here? Please let us know if that possibly helped with the freezing. 

Hi all,

Just wanted to add that we've seen this issue sporadically on our fleet of ~175 7420s as well.  It's resulted in random total system freezes (sometimes at a black screen, sometimes not) with no Windows BSOD logs being written.  

@DELL-Daniel V @DELL-Nat M There was a new Intel graphics driver released on 4/9/26 on the 7420 support page: 32.0.101.7084, A19.  Would you please be able to confirm whether we should continue with the engineering recommended driver A13 (which is ~1.5 years old) or attempt to use this new version that was just released.

Thank you!

Hi everyone,

The issue is reproducible on the latest version, 32.0.101.7084. The fastest way that we have found to replicate it is to set the "Turn my screen off after" timeout in Windows settings to the lowest (1 minute) and just tap the touchpad each time the screen turns off.

After a variable but reasonable amount of attempts, the condition will trigger and the console will freeze. Most often, it freezes on a black screen with only the cursor visible. If you perform a manually-initiated crash while it is frozen, WinDbg analysis will reveal the exact cause of the fault.

Our next posts will include one instance in which we performed this analysis. It is a clear circular wait deadlock which sometimes occurs after the Windows console process (csrss.exe) defers to igdkmdn64.sys (Intel Graphics kernel-mode driver) via dxgkrnl!DxgkPowerOnOffMonitor and toggles power to the internal display. Additionally, we have all but confirmed that the problem does not occur with the oldest version published on Dell's website, which is 31.0.101.3222.

This should be more than enough information for the engineering team.
