Prior to release, BIOS 1.10.1 was shared to several users with this issue and it appears to correct it. As Ivan_Pavlov3 suggested above, all should install it and retest. * Connect the provided external power adapter to the Laptop* The Laptop is not connected to any dock, external monitor, printer, drives, etc.* Download/Save the latest BIOS file to the Windows desktop* Close/end task all unnecessary software applications (Browsers, Dell SupportAssist, Dell Update Application, Dell Display Manager, Dell Display and Peripheral Manager, Steam, Anti-virus, etc.)* Find the saved BIOS file on the Windows desktop* Right click the file and choose, "Run as administrator". Note, you do not need to "extract" the file. Just run it* Follow the prompted instructions. The Laptop will reboot on its own, do not force it
Greetings community ! The company I work for has recently purchased a batch of Latitude 5431 laptops for a standard replacement and we started receiving numerous issue requests from our users. The issue is not consistent - may happen at any time, but once it occurs the laptop becomes almost unusably slow. During our investigation we found out that while the issue is active the CPU's performance is cut to no more than 10% regardless of the current load. So far we have tried almost everything without success :   - Dell's standard troubleshooting tools (no issues found)  - Update all drivers and firmware  - Update BIOS  - Restore BIOS factory default settings  - Edit Windows power plan to high performance. At this point we are running in circles. If anyone knows how to resolve this issue - please assist! Thank you!
