Latitude E7450 randomly shuts down

Same problem here, brand new 7450 out of the box for roughly 30 minutes and shutting down constantly.  Was happy to find this post so I know I immediately have to send it back, won't mess around.

I will keep this updated as to the status of the replacements & fix.

I have a few E7450's that experienced display issues.  These were resolved by applying the latest Intel HD drivers (and I upgraded the BIOS to A04).  However, I have one unit that keeps crashing...

I just reinstalled the Intel Dynamic Platform & Thermal Framework Drivers, and I set the associated service from "manual" to "automatic."  Fingers crossed.

Windows 7: The driver \Driver\WUDFRd failed to load for the device... error

Update: I called Dell same day as delivery regarding the shut down/thermal problem.  Diagnostics, during either the regular or thorough tests, showed a CPU temp spike to 102C which generated a warning and appeared to stop the test.  The temperature seemed to jump from 78C or so to 102 for just an instant, then settle right back to 78 or 80 and stay put.

Dell was quick to dispatch a replacement laptop, though it'll be another 2 weeks due to build.  I'm a little nervous about the consistent mention of "same or better" in the e-mail traffic as I had highly customized the laptop and was very specific on the phone about wanting the exact same thing (but working, of course).

Laptop was gorgeous otherwise.  Will check back in with results.  The mention of the thermal management software update sounds promising, I feel stupid saying that I didn't check to see whether it had all the updates.  I still have the bad unit, may unbox and see whats up.  Keep us posted.

I also have run into this same scenario on multiple stations. I have spoke to our Dell rep regarding these units randomly dying.  I have send my results to engineering  explaining these abnormal thermal temperature 102c  is also the highest I've seen. I reconsidering ordering these units and going back to E6540's. I currently have 90 7450 in production and averaging issues with 1-10 units. It is shame because they are well received by the end users due to the weight and performance offering .

Dear Ravi

I am having the same problem as Vajni , ( even worst ) I bought my laptop Dell 7450 ( I7 -5600) in Sept 2015 , and now Dell has replace the mother board 2 times , ( last one was in end of November 2015) . Today the same problem happen again , during one week randomly the screen turned black and back for couple of time and Sunday , God has called my E7450 to the haven .

I called Dell support in Indonesia, telling them the same story again about what’s happened to the laptop , and the answer was “ we are going to replace the mother board but we will ask a good one “ very weird answer .

I have been using dell since 1991 , without single problem , my last laptop was a E6400 Centrino , and had worked with this laptop in different harsh environment , ( never had single problem)

Now with this laptop pretending at the edge of the technology and high price , it is very frustrating to face such repeating situation without having Dell considering seriously this issue .

I would like Dell to replace my machine but apparently Indonesia support doesn’t seem to do so .

Least but not last , is to give up with Dell and seek other less branded but reliable machine with real support .

Really , really *** off customer .

Hi Dayak,

Since the replacement, my laptop shuts down sometimes but it must be a temperature issue. It happens when the fan opening is slightly blocked or I leave it on the charger and the laptop is left on a surface that does not dissipate the heat, like a sheet in the bed :)

With that mother board the cooling is challenging and the ultrabook concept does not help to the design at all. 

Unless I overheat it a but, this replacement is running smooth and reliably.

Cheers, 

Were you able to figure out of the A04 BIOS update did anything on these issues?

We are starting to get reports of the 7440 and 7450 models starting to run hot also....

SOLVED!

The Dell Latitude laptops and many others have a magnetic sensor on the bottom edge somewhere so that when the lid is closed, and the unseen magnet approaches, it goes into sleep (or hibernation mode).

If you are wearing a magnetic bracelet, like many of us do for "therapeutic purposes", your bracelet will often trigger a "sleep" or "hibernation".

Remove your bracelet for a while and give it a try - that should do it!

I have gone through two of these at my work. The first was not function properly at all.  The second one randomly began shutting down when plugged in.  I had to take it back to work to the docking station to get it to run.  Then I received a strange red warning about a tagging issue and had to take the battery out.  To do this you have to unscrew the bottom panel of the laptop.  We removed the battery and put the bottom cover back on and only run it on the docking station or plugged in directly.  The IT department is now ordering me another one.  I'm not impressed with the technical issues of this laptop. As a business model its a an unreliable laptop in the field with these issues.

Band new E7450 (January 2017) & I have the same issue.
