I'm facing windows 10 slow/non-responsive behavior (perhaps after 1809 update) and after doing many fixes mentioned online (like drivers update, services on/off, windows update etc) i ended up in finding a cpu frequency change.
When i run it in safemode, it run fast as expected on correct frequency 2Ghz. (see core speed)
Where as when i run it on normal mode, starts fine but after few minutes of idle time, it changes cpu freq. way too slow 0.4Ghz. (see core speed)
Initially i thought it is due to thermal condition of cpu, so i tested it with coretemp and it seems fine.
I also tried changing power plan (default to balanced on 1809) to high performance but no result.
I also tried setting SpeedStep to 'disabled' from BIOS but no change. Also updated BIOS to latest from Dell Update App.
Can any one help?
