It's the Monitor! Most laptops do NOT have an IPS Monitor and you should connect them to a calibrated IPS Monitor for final color ajustments. If you do not have a quality IPS monitor that is properly calibrated you will never get your colors right except by accident. See Arnaud Frich's excellent article on photographic color management:
http://www.color-management-guide.com/how-to-choose-monitor-for-photography.htmlFor a fairly current list of IPS monitors see:
http://www.144hzmonitors.com/best-photo-editing-monitor-2016/ Lots of CPU and GPU speed and lots of GPU and main system memory make the editing process go much faster and smoother: If you are a Windows 10 user please note Gaming Desktops and Gaming Laptops have plenty of this stuff. Note most photo editing software does not support multiple video cards so if you go the gaming desktop route invest in the best single video card with lots of memory not multiple video cards. And turn on the "Use Graphic Processor" feature as GPU's are designed to more rapidly process graphics than any CPU of the same generation. Also make certain you have something that allows your camera to transfer graphic images to your the computer. If your camera is fairly new it will most likely have WIFI. If not you will need a card reader that supports the same memory card as your camera uses. If you get a 4K monitor make certain the video output of your computer or laptop supports 4k.
If you are an Apple person all the same applies but make certain that you get the Apple Computer you get and the monitor you get can be connected. Many Monitors have "Apple" versions or are "Apple compatible". Also be very careful that the particular Apple computer or laptop you get even has a way to connect to an external monitor. Apple does not feel the least bit obligated to conform to any PC industry standard or to not completely change their interfaces when a new model comes out. Check your specifications carefully.
Note laptop touch pads are terrible when using photo editing software, a high quality mouse is a little better but do not come close to a Wacom graphics tablet. (You don't need the $800 one unless you have really great drawing skills. they have models under $100 that will fill most photographer's needs.)
LAST BUT NOT LEAST --- SHOOT RAW! and use or learn Lightroom/ or On1's raw editor due out in a few weeks that allow you do non-destructively edit raw files. You loose too much detail when you have your camera convert your photos to JPEG.
