The link probably doesn't work as it's no longer available........................................because I bought it!!
Here's the spec -
Inspiron 15R - N5110
Display: 15.6in High Definition (720p) LED Display with TrueLife
Processor: Intel Core i3-2310M (3M Cache, 2.10 GHz)
Hard Drive : 500GB Serial ATA (5400RPM)
8X DVD+/- RW Drive
English Genuine Windows 7 SP1 Home Premium (64Bit OS)
6 Cell Primary Battery, 48W
Wireless: Intel Centrino Wireless-N 1030 (1x2 b/g/n+ Bluetooth Combo Card)
Back Up Media Not Included
Black
4 GB DDR3 SDRAM 1333MHz (1 DIMMs)
Power Supply: 130W AC Adapter
Intel HD Graphics 3000 with up to 1.6GB Dynamic Video Memory
My only concern was that it has 1 DIMM, but looking on Google I think this meas the 4gb of memory is in one slot, which leaves a second one empty to upgrade?
