ACPI/APM Suspend?Forum: Laptops Topic: ACPI/APM Suspend? started by: sfabius Posted by sfabius on Feb. 26 2007,02:30
I am trying to get this laptop to suspend to ram, and then it will be ideal. I have searched the forums and googled and tried numerous things which don't work.ACPI works except for suspend. I read on one of the pages that the 2.4 kermel doesn't support S3 state. I tried anyway and, no it doesn't. I did "modprobe toshiba_acpi" and "modprobe ac" etc. OK, so I'll try APM, I think, which is reported to work on a site putting Debian on < this very machine >. So I add "noacpi" to grub. ACPI seems to load. I try "acpi=off" and the machine hangs on boot (just after reporting the CPU speed). I know the machine can do it; if I hit the power button while in grub, it suspends. Is there a way to turn it over to bios? I would like a suggestion on what to try next, if anyone can think of enything! Posted by Juanito on Feb. 26 2007,03:35
I've tried ACPI "suspend to ram" with a Dell laptop and DSL-N - one thing I found is that waking your machine up sucessfully may depend on how you booted DSL in the first place.I have seen several reports stating that you need to unload the USB modules prior to suspend and load them again on resume - I boot DSL from USB so it is unlikely to work for me. Also, on my Dell machine I need to add extra commands to wake the screen up after a "lid" event which would presumeably be needed after a "suspend to ram". I'd like to get "suspend to ram" working on my machine too - let me know how you get on. Posted by sfabius on Feb. 26 2007,16:26
I'll deal with waking if I ever get to sleep I was look at < this site > and it said to do the following to get ACPI suspend to ram to work:

This is the command for the 2.6.x kernel (i.e. DSL-N) - 'works for me except that my laptop goes into a coma...You have to do something different (as far as I remember) in the 2.4.x kernel. Posted by sfabius on Feb. 26 2007,18:00
Ok. So a search for kernel 2.4 ACPI suspend turns up < this very informative page > (refreshing in its straightforwardness). It is here that it says "S3 is currently _not_ supported by the 2.4.x kernel series in Linux." That would be my main problem.But still, then, why can't I boot with ACPI=off? I didn't realize we could get a 2.6 kernel with DSL. I will have to investigate how to do that. If you have any howto suggestions, please let me know! Posted by ^thehatsrule^ on Feb. 26 2007,18:24

Looks great, and might solve my problem. Two questions:1. Will it run on my Toshiba Laptop (~300 Mhz PIII, 96MbRAM, no CD boot, no USB boot)? 2. How hard will it be to install/upgrade from my existing DSL system? |
