I've been somewhat bummed by the long boot time of my Lenovo Z580 laptop although it's an 2.9 GHZ i7 processor with 8 GB of RAM. For Christmas, my lovely wife (with my assistance) ordered a Crucial solid state drive for it, along with an install kit which included Acronis software and a USB adapter that plugged into the new drive (same contacts as the original drive.)
After some failures, working with tech support I got the original disc cloned to the new solid state drive, and now boot time is only 30 seconds from off to fully functional! WOO HOO!!
I'll be interested to see whether the battery lasts longer as well...should be interesting to check it out.
