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.

Monitor & Printer Color Calibration - PC

Printing out images can sometimes produce different colors and tones than you might expect. Here are a few ways to make sure your screen and printer are properly calibrated.

DON'T USE STANDARD PRINTER/COPY PAPER!
Get a Professional Graphic Design Monitor; Even One Pre-Calibrated:

ViewSonic Professional 27 Inch 4K Monitor with 100% sRGB Rec709 14-bit 3D LUT Color Calibration for Photography and Graphic Design

Calibrate Your Monitor Colors - Windows 10:

Click Search or Cortana in the lower-left corner of your display.
Type "Calibrate Display Color".
Select "Calibrate Display Color" from the flyout menu to open "Display Color Calibration"
If your system has more than one monitor, move the "Display Color Calibration" application window to the display that you want to calibrate and then click Next.
Follow the instructions as they walk you through calibrating your monitor.

Display Color Management - Windows 10:

It's important that you make sure that both your monitor and your printer are using the proper ICC profile. You can see and change these profiles from the "Windows Color Management" dialog box.

To get there, follow these steps:

Click the "Windows Search" or "Cortana" icon in the lower-left corner of your screen.
Type "Color Management".
Click the Device drop-down menu.
Choose your monitor from the list.

Note that if you did not install the drivers that came with your monitor, Windows may recognize and install its own profile for your display. Some inexpensive displays may not come with ICC profiles, and in turn, draw their calibration info from one of Windows' several generic profiles. And remember that, as mentioned, a good number of monitors come calibrated for office settings; the monitor may require some additional tweaking to get colors to match more closely to what comes out of your printer.

Printer ICC Profile for Paper Being Used:

As for your printer's ICC profile, nowadays, nearly all printers come with them, which programs like Photoshop, Illustrator, and InDesign load and read as soon as you select the device from the printer list in the application's Print Settings (or equivalent) dialog box. You can also pick up ICC profiles from the hardware manufacturer's website or by contacting the company directly. When you have the profile in hand, you can install it in Windows in two steps:

Right-click on the ICC profile file (it has a .icc file extension)
Click "Install profile"

Hardware Color Profiler/Calibration Tool:

Monitor calibration kits and/or monitor-printer calibration kits, have been around for some time now and many of them work quite well. They range in cost from just less than $100 to more than $500. These devices can be your go-to for the entire process of calibration, or in addition to the steps listed previously.
