Suspend to ram on HP ze4400 - on resume, no keyboard/video

Any ideas? Fedora 7

Hello,

I was surprised to see how far linux has gone in M$ world when I installed Fedora7. On my HP DV8000 everything (including dialup, wireless, SD reader etc.) works.

The only remaining thing is the suspend/hibernate.

I am having the same problem. Linux has a very wide contributer community. I think as suspend requires some activities to stop and start after coming alive, not all the modules in kernel are very good at.

For suspend/hibernate I think we should give another 1 year or so for it to become mature...

suspend to ram works well with my dell e1505.
I had a similar machine to this HP with same problem a while back.

Could you plase try to suspend with minimum boot like init 1 and most kernel modules rmmod'ed and post back if it works?

Thanks,

Can you explain how to do so? Using pm-utils, or what?
so telinit 1 and rmmod most modules, then pm-suspend?

Yes that is what I mean.

Not that it is the solution but just out of curiosity. I will try the same...

This morning I tried to suspend from tty1 with init 1 and rmmod'ed almost all the modules. Still my HP could not get back on its feet on resume....

Hmmm.

My HP ze4427 and HP ze5170 both suffer the same problem. My HP dv4217, however, works flawlessly in this regard.

For anyone to really be able to help you all, you need to give some specs on your laptop's like wireless/video.

Have any of you tried this page?

Hi There,

I tried to start my system with emercengy boot option (which loads minimum of everything). Then tried pm-suspend. That did not worked either.

May be starting with the emergency olsa skips some of the modules required to come back from suspend mode, I do not know. But it did not work out...

I will do what you asked for jlc...
