Method 2 : Disable Intel display power saving technology
Disabling Intel display power saving technology is complicated by the fact that
the Intel Graphics Control Panel no longer shows the option for disabling it.
Registry work is now required for that:
- Launch regedit
- Navigate to
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4d36e968-e325-11ce-bfc1-08002be10318}\0001
- Find
FeatureTestControl
, double-click it and copy its value to the clipboard
(mine is 8280
)
- Open the Calculator, set it to Programmer mode, click HEX, then paste the value
- Click BIN (mine: 1000001010000000)
- Change the 5th bit from the end to 1 (mine: 1000001010010000)
- Click again on HEX and copy to the clipboard (Ctrl-C)
- Set
FeatureTestControl
to this value
- Reboot
A PowerShell package that does all these manipulations can be found in
Github dpst-control.
After unzipping, you may use its scripts, named appropriately
get-status.bat
, disable-dpst.bat
and enable-dpst.bat
.
Method 3 : Run Power troubleshooter
- Run Settings > Update & Security > Troubleshoot
- Click Power > Run the troubleshooter
