I have installed Ubuntu 12.10 on my Acer Aspire 5742G recently but I can't neither put it to hibernation nor suspend it. If I hibernate it then when I press the power to wake it up, it doesn't show anything on the display and I have to force power it down (by pressing the power for a few seconds), and press the power again. Even sometimes the same thing happens when I shut down the laptop.

I tried TuxOnIce, without success.

As far as I know it's not a bug in 12.10. My internal wireless card is not working properly and I am using a USB wireless card. Do you think it might be the reason? Any one has an idea how to solve this problem?

how much RAM do you have? Do you have the 8GB model or a lesser one? Most of the time it is usually RAM that causes that. – mojo706 Jan 30 '13 at 4:46
It's 4GB. Is it because of that? – Adham Jan 30 '13 at 12:00
It might be you may have many running system processes. Do you have MYSQL, APACHE or any DB or server installed? – mojo706 Jan 30 '13 at 13:11
No, I am not running any of them on the machine. It's a clean install, and I have not installed any software on that yet. – Adham Jan 31 '13 at 0:36
