Suspend Mode
Hi all,
I bought an old 486-based laptop recently (Dell Latitude XP 450C), and
successfully installed Debian linux on it. I'm a newbie to both laptops
and to Debian, but not to linux (I've been running linux since 1992).
I'm wondering about the "suspend" mode feature on this machine. If I
close the lid while the machine is running, it seems to go into some
power-saving mode. It stops responding to the network, etc.
That's great, except: the clock stops running!
I closed the lid last night, and when I opened it again this morning, the
system time was eight hours slow :(
So how do I fix this? The hardware clock still keeps time, so it ought to
be a simple matter of running "hwclock --hwtosys" upon resume, no?
How do I set this up?
According to information on Dell's web site, when I close the lid, the
computer enters a "suspend mode" where it turns off CPU clock, disk motor,
monitor, etc.
The machine also has a "suspend to disk" mode, in which it is supposed to
dump its memory contents to a "special partition" on the disk, and then
shut off the power completely. This way, one can resume exactly where one
left off. I wiped and repartitioned the disk when I installed linux, so I
no longer have the special partition on it. But this sounds like a nifty
feature. Does it work with linux? Supposing it is large enough, can I set
up the machine to use the *swap* partition for "suspend to disk"?
