Microsoft Surface Random "Kernel Power" Shutdown

Microsoft Surface & Surface Pro
"Kernel Power" Shut Down Bug

Here are a few ways you can fix the random "Kernel Power" shutdown issue that some Microsoft Surface and Surface Pro systems can have. 
The issue seems to be tied to the Intel Graphics/Display driver and/or the associated Intel Graphics Command Center software settings.

Option 1: Update the display drivers to the latest version (from Intel, not Microsoft):

• Download and install the latest display drivers from Intel:
  https://www.intel.com/content/www/us/en/download/19344/intel-graphics-windows-dch-drivers.html

Option 2: Disable the "Panel Self Refresh" option in the Intel Graphics Command Center:

• Install the Intel Graphics Command Center from the Microsoft Store. 
• Open up the Intel Graphics Command Center software after it has been installed
• Go to System > Power and look for "Panel Self Refresh"
• Turn it off for both "On Battery" and "Plugged In"

Option 3: Change the display drivers to the Microsoft Basic Display Adapter:

• Open the Device Manager.
• Expand "Display Adapters".
• Right-click on "Intel(R) Iris(R) Plus Graphics" and select "Update driver".
• Choose "Browse my computer for driver software".
• Choose "Let me pick from a list of available drivers on my computer".
• Select "Microsoft Basic Display Adapter" and click Next to install the drivers.

 

Option 4: Remove "Modern Standby" features and create a new (non-balanced) power plan:

• Open the Registry Editor and navigate to: "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Power".
• Change the "CsEnabled" value from '1' to '0'. 
• Click OK and restart the Surface Pro.
• If you do not see the "CsEnabled" subkey, create it by right-clicking on "Power", selecting "New", and then click "DWORD (32-bit) Value" and typing "CsEnabled" as the value name, and then press Enter.
• Now you should be able to change the "CsEnabled" value from '1' to '0'. 
• Click OK and restart the Surface Pro!

One or all of these tricks might be needed to correct the Kernel Power shutdown bug. But I have gotten the problem fixed for clients by using one, or all, of the tricks listed above!

Mac Battery/Power Management System Calibration

Calibrating The Battery/Power Management System of a Mac Is Easy To Do!

On a new Apple computer, or after a new battery is installed...

Step 1 – Charge The Battery To 100%

• Shut down the computer and then connect the power adapter.
• Keep the computer plugged in until the light on the power connector turns green indicating a 100% charge.

Step 2 – Charge Two More Hours

• After the battery is 100% charged, keep the power adapter plugged into the computer for an additional 2+ hours. 
• The computer can be powered up and used during this time.

Step 3 – Temporarily Change the Energy Saver Settings

• If the computer is off, you'll need to turn it on.
• In OS X System Preferences click on the Energy Saver preferences.
• In the Energy Saver / Battery preferences:
• Set the "Turn display off after:" slider to "Never"
• Various Mac models may have two sliders for "computer sleep" and "display sleep". If you have two sliders, simply slide both to the right to set them to "Never"
• UNCHECK "Put hard disks to sleep when possible"
• UNCHECK "Slightly dim the display while on battery power"
• Note: The location/existence of certain settings may shift or vary depending on your computer model or OS version.
• In the Energy Saver / Power Adapter preferences:
• Set the "Turn display off after:" slider to "Never"
• Various Mac models may have two sliders for "computer sleep" and "display sleep". If you have two sliders, simply slide both to the right to set them to "Never"
• CHECK "Prevent computer from sleeping automatically when the display is off"
• Note: this setting may or may not be available depending on your model or OS version.
• UNCHECK "Put hard disks to sleep when possible"
• Note: The location/existence of certain settings may shift or vary depending on your computer model or OS version.

Step 5 – Unplug And Drain The Battery

• Unplug the power adapter.
• Leave the computer on until it automatically shuts down.
• You can use the computer during this step, but don't put the computer through heavy use to deplete the battery faster. Steady, even usage is better for power system calibration.

Step 6 – Leave It Off And Unplugged

• After the computer has automatically shut down, leave it shut down for at least 5 hours or overnight. 
• This will ensure the battery is completely drained of energy.

Step 7 – Charge To 100% Again

• Plug the computer back in until the battery is 100% charged.
• While plugged in, the computer can be used.
• This is also a good time to go back and select your desired Energy Saver preferences.

AND THAT'S IT!

After this essential calibration, the new battery will be able to achieve its fullest charge and reach its full lifespan, and the system will display an accurate battery level. You can also reuse these steps to recalibrate the power management system every few months if desired.
