I am on Acer 5742G. Here are some specs
Processor : Intel Core i5-460M Mobile Processor (3MB Intel Smart Cache, 2.53GHz)
Chipset : Mobile Intel HM55 Express
Memory : Up to 3GB DDR3 SDRAM
Storage : Up to 500GB SATA hard drive, 5400RPM
Video : NVIDIA GeForce 420M graphics
I have 3.3GB of Swap partition and 2.3GB of ram. But whenever I try to hibernate it says "not enough free swap".
Here is the output of free command
total used free shared buffers cached
Mem: 2319 1304
1014 0 453 544
-/+ buffers/cache: 306 2012
Swap: 3344 0 3344
So you see there is lots of free swap space. Then why is it not hibernating?
