|Vista does take longer to boot on a laptop. How is the speed of operation once your system is booted? Is normal speed of operation good enough?|
Slow boot can be related to having too many programs starting up when you boot. OEM's often load computers down with unnecessary startup software, or you could even have malware being started up. You need to be careful doing this, but you can run a program called "msconfig" on your laptop, and see all the programs that are started when your laptop boots. If you go through those programs, and be sure that you understand what each one is, disable those that you're sure you don't need, or that are known malware/spyware. But be very careful, as laptops have startup programs that are needed for the hardware that are not present on desktops, like software for the built-in touchpad, and so on. And your antivirus software starts at this point, as well. Don't turn off anything that you don't know what it's for.
At any rate, if you can turn off some programs that are not needed at startup time using "msconfig", your boot will run faster.
But again, be careful, read about this on the internet before you do it, and make sure that you understand which programs that your computer needs at startup.
