Buy this computer if you need a really great, full HD screen and a capable computer to do surfing, microsoft office sort of tasks, watching netflix, etc. Becomes a snappy surfing and binge watching champion if you throw an extra 4gb of memory in it and another SDD for storing your files.Installing a memory (RAM) upgrade is easy. You turn the computer over, remove several small screws and then gently but firmly pry off the bottom plate. You will see one RAM module already installed. Snap the additional one into the open slot. If connected correctly, you are done. No changes needed in BIOS.Installing a 2.5 HDD or SSD is a more difficult process that I would not recommend to folks who have not done a computer build or PC repair before. At first glance it appears that you can just plug your SATA drive in and close up the computer. This is not the case! You need to unscrew the SATA controller board -- you will notice that it isn't connected to anything! You will see a tiny ribbon cable in the same spot. You need to pick up that cable and clip the end of the ribbon marked HDD into the connector on the SATA controller board by lifting the tiny beige clip on the SATA controller and hooking the prongs of the ribbon cable's end into the slot before snapping the beige clip into place. Plug in your drive to the SATA connector and place this whole assembly onto the plastic sheeting with the SATA controller lined up next to the open connector on the motherboard that is labelled HDD0 (very small label). Take the end of the ribbon cabled marked Motherboard and plug that into the HDD0 connector on the motherboard, using the clip as before. Then you will screw the drive into the two metal rails to keep it in place, and finally screw the SATA controller board into it's new spot. Make sure nothing is wiggling or loose, make sure the ribbon cable ends are snapped in and not floating around. Then close up the laptop case. WHEW. Then you need to boot into BIOS by tapping F2 while the computer is starting. Verify that you see your drive listed in HDD0. Proceed to boot into windows and use the windows Disk Management tool to format your new drive!
