How do you pack up your laptop and bring it somewhere else without it melting down in the bag? Just make sure nothing is burning CPU, pack it up, and hope for the best?
Depends what you meant be 'save your sessions.' If you have an entire environment setup with multiple applications open in various states, then no, you can't 'save state' in any way that I know of (other than suspend-to-disk). It can also be a pain in the ass to setup said environment again.
On the flip side:
- Using suspend-to-RAM is less secure.
- Enabling secure swap (at least on Linux with in a password-less setup[1]) doesn't work with suspend-to-disk.
[1] In a password-less setup, there is no way to recover the swap after a fresh boot since the key is regenerated on every boot (at least it was the case the last time that I manually setup encrypted swap).
I have been using my notebook lately while on the move as an external battery for the tablet. Just plug the usb, put the laptop on suspend and you have 12 hours of decent performance ahead of you - so suspend is somewhat important for me right now. (8 hours in a bus is testing experience)
One of my favorite features on my current laptop is the USB port that is connected directly to the battery, so it charges even when the laptop is not turned on.
What laptop is this? Is this an advertised feature or something that you only got information on in some obscure way (newsgroups, forums, etc vs. the official manual)?
Alienware M11X R2. It's not really advertised, I just noticed the option in the bios one day - http://www.techmonsters.com/DellTraining/bin/Foundation2010/... . It's ridiculously useful when travelling - if I don't use my laptop I get an extra 2/3 days worth of battery for my phone.
