I’ve just had a brief look at ’suspend’ modes with Ubuntu on my Compaq Presario 2103EA.
First off, ‘Hibernate’ (Suspend to Disk) works fine, the image is saved from RAM fairly quickly considering there is about 570MiB installed. Starting up again takes just a little less time than a normal boot.
‘Suspend’ (Suspend to RAM) however, does not work. The system goes down quickly and the power light begins it’s rise/fall strobe. On restarting, the system fan spins up and the power light comes on but the wireless and wired NICs stay off, the screen staying blank. This is pretty much as expected as the Presario 2100s are not renowned for their standards compliance when it comes to ACPI.
I had a poke around on Google and found plenty of other people with the same issue - I will look in more detail soon to see if any found solutions.
So, if you do have Ubuntu on a Presario 2100, don’t use ‘Hibernate’ if you value your data in unclosed apps! (You should be saving before a hibernate anyway)
If you need statefull power-down, you should use ‘Suspend’; otherwise a normal power-down and power-up will be just as good time-wise.
