Latitude E6410 resume from S3 Suspend (on batteries)

Latitude E6410 (Intel i7) fails to resume (total system freeze within first 3 seconds) from S3 Sleep (STR) when resumed running on battery power. Sometimes first resume cycle passes and problem occurs  during 2nd or 3rd suspend/resume cycle.  When the laptop is running on AC-power the resume works 100% correctly.

This issue disappears when SpeedStep is disabled in BIOS.

It seems like a BIOS bug (tested with rev. A05)

OS:  Linux 2.6.35 and 2.6.36 x64, Windows 7 Ultimate 32-bit

Update:  Dell phone support classified the issue as HW problem; laptop servicing has been scheduled which should hopefully resolve the issue.

Replaced:

- mainboard (which includes nVidia discrete GPU)

- CPU

- Display

No success so far. Remains to be tested with a different battery (currently using 9-cell hi-capacity battery with Express Charge)

Finally the issue has been officially classified by Dell as BIOS bug, there's no intermediate solution available until next release of BIOS (except from never resuming the laptop on battery power or having speed-step disabled, obviously).

I would gladly test-out a beta BIOS;  Dell, please, feel free to contact me. I would provide you with my service in order that you could check-out the details of my HW specs and to provide you with feedback on the appropriate BIOS beta.

Herroux,

I've had my E6410 for about two weeks and have observed the same condition.  Mine is the same configuration but with 64-bit, 8Gigs of RAM.

You are absolutely correct about waking from standby.  I have observed the exact same symptoms and it was pretty frustrating.

I may have something that will work for you.  If you can live with changing your power options from "standby" (S3) to "hibernate" (S4), your Latitude will probably wake normally.

No guarantee that this is the best workaround and it may not be as fast for you, but I tried doing this after I read one of your earlier posts, and so far, during the past week, it seems to be working perfectly for me.

I don't know what trade-off disabling speed-step in the BIOS would introduce, but I was somewhat skeptical when I you reported that Dell Customer Support suspected that it was a defective unit.  I'm sure they did their troubleshooting correctly, but I couldn't imagine that I'd have the exact same issue with my machine.

I believe I'll be looking for the A06 BIOS on a regular basis.

Herroux,

 

Here's the information from my PC.  We have similar models and features, but I don't have the Solid State Drive.  I opted for a 7200RPM drive.

The only reason I chose this machine was because I really, really need a Dell laptop with a USB 3.0 port.  What's that you say? This one doesn't have one of those.  Correct.  But it does come with an ExpressCard slot.  This is not a great solution, but the configuration does allow me to use a third party "ExpressCard to dual USB 3.0 port" adapter.

Herroux,

Another update.

I've  been working on this for some time.  What's been interesting is that each time, I get to the point where the "Resuming Windows" animated graphics appears and then, a few seconds later, the screen blanks, including the LED backlighting.

What I think may be happening is that it's definitely related to the "suspend" and "hibernation" modes, and the relationship between them.

I noted that you'd mentioned Linux OS on your earliest post so I don't know whether or not you're principally running Windows, or whether this applies to you.

What I've found in my case is that there's a point in the Windows 7 power management options where the we set the "sleep" and "hibernate" options.  The default setting for S3 sleep may be five or ten minutes, or some other period of time.  But S4 hibernate's default is set for 360 minutes.  If the machine is left alone, Windows thinks you need to save yourself from a potential calamity, so sleep automatically changes over to hibernate .

For example,

When I close the lid, my machine goes to S3 sleep mode.  There's a little blue LED on the top of the unit near the hinge that gently blinks on and off, indicating it's snoozing.  According to the default power plan I'd selected, after 360 minutes, or six hours, of this kind of "sleep", my machine will "wake" for just enough time to write information to disk, go into hibernation, and then power down completely.  From this point, all hope is lost.

Upon attempting  to restore from S4, the machine becomes confused and the "resuming windows" graphic appears, which in itself, proves that it is trying to restore from hibernate.  Normally, when you come back from unmolested S3, the machine simply awakes from "Standby", and there is no such graphic.

I have changed my power management to a shorter standby and have induced the machine to become a sleeping beauty much quicker.  In fact, I can now get it to become comatose in a minute or two.

My new workaround is to set the hibernate option in my advanced power management window to "Never" so that my E6410 never invokes S4 hibernation.  It's probably not the best option, but I have the larger 9-cell battery and as long as the lid is closed, the machine not drawing much current.  I am confident that I will be able to charge it before it completely runs down.

So now I have a question, is this a problem with the machine or with the OS?
