Latitude 7420: Hibernating mode is not working
Symptoms are: PC is able to switch to hibernate mode only once (after new start or reboot). After system wake up - is unable to switch to hibernate mode anymore. Screen turns off, fan is starting work faster, and after 20-30 sec get the maximum performance. System is heating up. Just one way to turn it off – push Power button for long period of time.
I've checked and tried everything from HERE , HERE and HERE.
Nothing help.
- BIOS version 1.14.1. I tried ver. 1.16.1 (what disappeared from the site) - no improvements;
- BIOS doesn’t have “USB Wake Support” and Disable “Deep Sleep Control” options;
- Fast Startup option in Power menu disabled;
- Disconnection any type of external device (like mouse) didn’t solve the issue;
- DELL SupportAssist can’t pass the Standby/Hibernate troubleshooting test. System goes to sleep mode normally but not back as expected. If wake up system manually, SupportAssist app will not respond;
- Refresh of hibernate file by " powercfg -h “ command didn’t help;
- SFC scan Command to Repair System Files didn’t help;
- Windows Power troubleshooter didn’t find any issue;
- Registry Key CsEnabled doesn’t exist;
- To add “PlatformAoAcOverride” Registry Key didn’t help;
- The following sleep states are available on this system (powercfg /a):
1. Standby (S0 Low Power Idle) Network Connected
2. Hibernate
S1-S3 states are not supported
- Clean boot didn’t help;
- Create a new user didn’t help;
- DISM to restoration of OS health didn’t help;
This is almost new PC with fresh installation of Windows 10 Corporate.
DELL support tried to solve this issue but the last solution provided - to re-install OS what just installed Why not to change PC to normal one? Like Lenovo ThinkPad or Apple MacBook Pro
