Suspend to ram will always drain batteries since the ram requires energy to be kept alive. Maybe you want suspend to disk?

Re: [Haifux] ACPI on IBM R40
Thanks for prompt reply. I should have stressed that I'm talking about UNUSUAL draining - as opposed to APM sleep I used in 2.4. My battery is over in 10 hours, while previously it was at least 4-5 days. Suspend to disk is a good idea, but it doesn't really work for my Radeon7500 video card, i.e. it suspends, but comes back with garbaged display, impossible to see anything.

CPUs have several sleep modes, some are better at saving energy than others, though I know no details on this more than that. Maybe some other learned Kernel hacker will know more, I've been dealing too much with networking and too little with other areas.

Can't help you with the ACPI problem (I've been trying to steer clear of it for years now and am still in apm land) but switching to a text console before suspending might do the trick, using e.g. chvt(1).
