Laptops are usually loaded with what I call crapware. Bunch of software that you don't need and they are always running when you turn the computer on. If there are a lot of icons in the systray (next to clock), all those programs are running in the background taking away resources.
You can remove them from the startup. I don't like to mess up msconfig. I use a free software called RegSeeker. You can remove items from startup and will make a backup of any change you make. Be sure what you are deleting.
Another option is optimization software that tries to make your computer run better. You'll have to search for it.
