Laptop Sleep Issue

[Adam Trotter]

I have a problem with my wife's laptop entering sleep mode when I don't want
it to. The laptop is a Toshiba Qosmio F45-AV411.

The laptop works great... until she plays a game. It doesn't seem to matter
what, anything 3D intensive is enough. After a few minutes of gaming, the
laptop will simply put itself to sleep. I don't think heat is an issue, the
laptop does not feel hot to the touch at all. I am 100% positive that
everything related to putting the PC to sleep is disabled, the power profile
she is using is high performance. I enabled the Kernel-Power diagnostic
log, and when the laptop puts itself to sleep, this is logged:

Does anyone have a clue what that code means? I can't find any
documentation about this event online at all. I don't know if it is a
hardware issue or not, but knowing the meaning of that error code would be a
great start.

Thanks a lot!

error code 2147483649 in decimal equates to 0x80000001 in hex, or -1 in
signed magnitude and as such may not have much significance.

really long long shot, could there be some keyboard combination used during
gaming that is triggering a sleep command ?

[Adam Trotter]

I wish it was a keyboard shortcut, but I'm almost positive it's not

I never thought about converting that number to hex... you're right,
probably doesn't mean too much in this case . Another thing that is
logged, this one from the ACPI Diagnostic log, is this:

Unexpected GPE event was fired on GPE bits that should be disabled.

I have no clue what that one means , but I'm wanting to go out on a limb
and say it could be a BIOS bug?

 

[Michael Walraven]

A simple check I would do is to check the Device Manager list for anything
with a flag on it (and view hidden devices as well). Probably won't show
anything but is easy.

As problems seems to touch on ACPI, and on 3D video I would do two things.
First check if there is an update for the BIOS on your machine. Second check
for latest video drivers from the Toshiba site (not from the video card
maker site).

Also some times there is a problem with Vista not seeing the proper hardware
when it is started up. A recheck of the hardware can be forced by restarting
with the HAL checking enabled.

in
msconfig
boot tab
advanced options button
check the 'detect HAL' option
(HAL Hardware abstraction layer, sits between the hardware and the operating
system)

for instance if the BIOS is changed, sometimes Vista has to be forced to see
the change.
(It is not done every startup as it would slow down the startup and normally
the hardware does not change).

Also there may be updates for your machine available from Toshiba, check
their site, especially for ones having to do with chipsets or ACPI.

standard warning, free advice is worth every penny, be sure to do a system
checkpoint before following anyone's advice.

I have that Vista SP2 Beta has improved the handling of sleep mode on my
wireless laptop.

 

[Adam Trotter]

I have tried the HAL check, it didn't help.

The laptop is running the latest BIOS already. I have also already tried
drivers, both the ones on the Toshiba website and the latest ones from
Intel. The problem exists with either set of drivers.

I will probably give the beta of SP2 a try and see if it helps.

I am very curious as to what the GPE event message means.

 

[Michael Walraven]

Sorry I wasn't able to help. Hope you find the problem.

Michael

 

[Adam Trotter]

No problem, I appreciate the attempt.

I'm installing the SP2 beta now... will post back when it's done as to
rather or not it helped.

 

[Adam Trotter]

SP2 did not help at all.

Does anyone here from MSFT know what the ACPI log error means?
