Missing processor power management settings option in advanced power options settings

Recently receiving an Acer laptop, I saw it was running a bit hot and wanted to adjust the Processor power management options. However, I found them gone when going into Advanced power options I found the CPU options which allow adjusting such things as Minimum processor state, Maximum processor state, and Cooling policy.

Other options were missing too – PCI Express, USB settings, Intel graphics settings, and Multimedia settings, were all gone from the options.

Thankfully there is a very easy solution. It requires opening  and making a minor change. Even if you’ve never messed with regedit before, you should have no problem here.

1. While in Windows press the Windows key + R. Alternatively you can click the Start button.
2. Type “regedit”. This will open the registry editor.
3. Navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power
4. Double click CsEnabled and change the Value data from 1 to 0, and then click or tap OK.
5. Restart the laptop.
6. Check your Advanced power settings and you should see the full array of options restored.
