Hello,

 For friends I try to update the very old vostro 3450 : 
1- I replace 4Gb RAM with new 8Gb RAM
2- I replace old 750Gb HDD by a SSD 128Gb (port Sata1)
3- I replace DVD player by cart with the old 750Gb HDD inside (port Sata2 optical)
4- I replace mainboard battery
5- I replace the laptop battery
6- I upgrade from BIOS A07 to A13
7- Last I install clean Windows 8.1 (all devices are recognize)

Now if I boot (1st boot) it goes very fast. Everything is very smooth.

The problem comes if I reboot or I shutdown the laptop : It take more than 10min with blank screen (you don't see anything on it except that you know that the laptop is still ON). Why??..... :((

I try this : I remove the cart with the old 750Gb HDD inside (port Sata2 optical) and it become normal again. Start fast, reboot and shutdown fast.

Someone understand this please ?? I really need to use the cart with the old 750Gb HDD inside (port Sata2 optical) for this laptop.
