Suspend mode freeze

[lnx64]

This is the only hardware bug I have on this laptop and hopefully I can get it fixed, because otherwise I do like Linux.. I'm making a Fedora 13 disk to see if it does it too on that distro..

The specs:
Ubuntu 10.04 LTS 64-Bit
Compaq CQ61-313US
AMD Dual Core Athlon II M300 2GHz 64-Bit
4GB RAM, 250GB SATA HD
ATI Radeon 4200 (Using either OSS or Proprietary Driver)
Insyde H20 BIOS F.15

The problem: Doesn't resume from sleep/suspend to RAM... LCD stays black with no backlight. Hibername/suspend to disk works fine however. When attemping to resume from sleep, there is also no HD activity. I'm forced to hold down the power button at this point. But when attempting to power back on, there is no POST, and instead the caps and numlock light flashes twice, which the HP manual says BIOS Corruption. I'm forced at this point, to pull the battery and AC adapter, and replace them both, and the laptop boots fine.. The laptop has no problems with sleep mode in Windows at all, and it's only in Ubuntu. I tried other same model laptops, and they all do the same thing..

I made a video of this problem: Youtube video pEsF72DPLSo
(I can't post the full link yet)

Hopefully someone can troubleshoot this. I tried the Ubuntu forums, but it was 12 bumps in and not a reply..

EDIT: I just tried Fedora. It affects it too..

And this reply won't be really helpful to solve your problem.

There are many suspend software like swsusp, pm-utils, suspend, suspend-s2ram... all working on kernel suspend-resume modules, and interacting with ACPI settings and with BIOS settings. You would have much to dig to know what is being used and how on your machine. Worst, a failed resume does not debug any information anywhere. It would be much time-costly with no guarantee of success.

So the simplest way is to try with another distro. It's working fine on my laptop with Mandriva 2010.1, but worked only half-way with 2010.0 and yet fine with 2009.0. You may also try another Ubuntu release.

It's not surprising you did not have any reply. Good luck !

My BIOS has pretty much no settings at all in it, HP crippled it (of which I contacted HP in an attempt to get the BIOS unlocked, but so far no dice)..

I did actually try "s2ram" but that also does the same thing.. It actually seems all utilities do it..

But I just tried another distro, Fedora, with the same exact identical results, including something that happens on ubuntu, having to right click networking icon and re-enable networking, upon cold boot...

Everything else works fine enough though for me to stay on Linux, but so far, every distro does the same thing. I did try Debian, same thing..

I used to use Mandrake since version 7, but since 9 I gave it up and moved to Ubuntu. I forget why I gave it up, but I think it was too many bugs..

Check the Screen Saver and Power Saving settings.
I had some conflict between the two, and it would lock my system out.

Screensaver is disabled, no need for it, and power saving settings are all set to no automatic setting, i want control over it, not the OS..

Thing is though, it corrupts the BIOS on resume, requiring a pull of the battery and AC cord, something there is terribly wrong.

Right, something is wrong.
Try these:
(1) run Ubuntu from a Live-CD, directly into RAM.
(2) Have you tried the 32bit distro Live-CD ?

Yes, I have tried live CD's, and 32-bit distros, they do the same thing.. I also tried other distrobution, EVERY distro I could get my hands onto, do the same thing...

Inx64,
Well, then maybe you should just get another set of hardware from Geeks.com, $169, and start this project over.
Some wierd hardware issue, and perhaps a bad chip.
You could be chasing it forever.
I am far too old to contemplate that option!

Let this thread/forum know of any further developments.

This is a laptop that cost me months of saving up for, that is NOT an option.

Not a bad chip, as I stated, other same models, do the same thing. I also did some Googling and found some Toshibas doing this too.

There seems to be something wrong with the way the linux kernel suspends these laptops.. I think a fix needs to be tested/issued.

It would guess it's some hardware not ill-functioning but designed in some non-standard proprietary fashion. Major computer makers do this (as far as I understood). Linux works according to standardized references and cannot always workaround proprietary designs. You may try flashing the BIOS with a non HP one, if that's possible.
