So I have a Lenovo IdeaPad U400, 14 inch, 2.4GHZ x4 (2nd Gen), Core i5, 8GB RAM DDR, 500 GB HDD, DVD RW, Windows 7 home premium,Wireless LAN + GIGABIT. And I want to buy a Lenovo Flex 2 15D, 15.6 Inch touch screen laptop,AMD A6-6310, 1.80GHz Processor with 2.40GHz Max Turbo, 4 GB DDR3 RAM, 500 GB 5400 rpm Hard Drive, 15.6-Inch HD (1366 x 768) LED Backlight Display with 10-Point Multi-Touch, and Windows 8.1. I was wondering what parts I could Transfer from the Lenovo IdeaPad to the Lenovo Flex? Or should I just Fix my Old Lenovos Case (which has taken some drop damage) by buying a whole new casing? The insides work perfectly except the casing makes it difficult to operate. The Bottom is coming off so I have to tape it all together, and its cracked on the joint that connects the screen to the rest of the key board, so I have to open it up slowly so it dose not crack more.
