Yes! First you can use command free to find yhe size of swap using.
then just do the following commands
mkdir swap
cd swap
sudo dd if=/dev/zero of=swapfile bs=1024 count=100000
to create swap file with a size 1024000Byte ( count)
after swap file was created,use sudo mkswap swapfile to convert the file to a swap file.
use sudo swapon swapfile to active the swap file.

Some laptops don't support suspend/hibernating under Linux, this depends on their hardware I guess. But you can You try this.

Stop the computer from suspending when the lid is closed
If you don't want the computer to suspend when you close the lid, you can change the settings for that behavior. To set the computer to blank the screen, rather than suspend, when the lid is closed:
Be very careful if you change this setting. Some laptops can overheat if they are left running with the lid closed, especially if they are in a confined place like a backpack.
Open the Terminal application from the Dash.
To change the setting used when running on battery power, type this command and press Enter:

Code:

gsettings set org.gnome.settings-daemon.plugin.power lid-close-battery-action blank

To change the setting used when running on AC power, type this command and press Enter:

Code:

gsettings set org.gnome.settings-daemon.plugin.power lid-close-ac-action blank

There are other settings available besides "blank," such as "nothing," which causes the computer to do nothing.

I copied that from this link https://help.ubuntu.com/11.10/ubuntu...-closelid.html
Good luck to you!

Increasing your Swap might be a good idea if you dont have sufficient RAM installed in your computer.
But even if you do have a large swap partition or ton of RAM doesn't not ensures your laptop hardware supports hibernation / suspend under Linux due to hardware incompatibilities.

However you can select a different behavior for your PC when you close the lid.

Good luck to you.

If you "man dd" command, you will find that the number followed count can have a suffix of K,M and G. In you case, you can use "count=4G" or "count=4000M".

Following is what the manual of dd says
BLOCKS and BYTES may be followed by the following multiplicative suffixes: c =1, w =2, b =512, kB
=1000, K =1024, MB =1000*1000, M =1024*1024, xM =M GB =1000*1000*1000, G =1024*1024*1024, and so on
for T, P, E, Z, Y.

That is an awful highlight colour - almost unreadable. Leave it as black, and use [quote] tags instead would be more useful.

To delete the small file, simply

Code:

rm swapfile

Then create it bigger again - it can be any name BTW.
