UNSOLVED
Latitude 5430, BIOS 1.10 update, slow CPU
Good day all,
We are currently observing a problem after updating the BIOS Version from 1.8.3 to 1.10. In my company, more than 10 devices are now affected. Either immediately after booting the laptop or after a few hours, the CPU is being down clocked to about 0.40 GHz.
The only thing we could do was downgrade the BIOS back to 1.8.3. CPU performance has improved after downgrade. Varies from ~1.30 GHz up to ~2.50 GHz.
So far, I have not found any forum entries with the same problem.
Best Regards,
Dino

We are having the same thing on 2 devices. Also Latitude 5430. Happened after BIOS update. Will try to downgrade BIOS and see if it improves anything.

We had this problem as well. Downgrading to 1.8.3 fixed the problem.
Now BIOS 1.11.2 is available. @DELL-Chris M Does this version solve the performance problem that occurred under 1.10.0?
There is nothing in the changelog that clearly indicates this.

Unknown. We only see the same changelog that you see. All you can do is try it.

If you have time, reply to the Dell agents private messages with this =
1. Update the BIOS to 1.10
2. Capture a video in Task Manager which shows decrease in performance
3. Downgrade the BIOS
4. Capture a video again in Task Manager which shows improvement in performance
