Z600 screen restore

Z600 screen restore

[Ivor Hewitt]

Hi,
I have a Sony vaio Z600-hek (same as US model Z505). Which I've been trying to 
get working with ACPI for a while....

On S3 restore the screen would power up and flash briefly and then power down 
immediately although the machine was now up and running. 

using "acpi_sleep=s3_mode" makes no difference.
"acpi_sleep=s3_bios" causes the machine to crash on s3 restore.

but if I comment out the two tests:-

#       testl   $1, video_flags - wakeup_code
#       jz      1f
and
#       testl   $2, video_flags - wakeup_code
#       jz      1f

the machine restores from s3 successfully and the screen powers up... so that 
appears to be the area of the problem...
any suggestions what the 'correct' fix for this would be?

Cheers,

-- 
Ivor Hewitt.

I guess it calls for a documentation patch. Pavel?

OK. Sorry, I didn't read your original mail carefully enough,
before responding.

Actually, commenting those lines is equivalent to passing
"acpi_sleep=s3_bios acpi_sleep=s3_mode". So, even that 
should work for you.

Oh I didn't realise you could pass both in at the same time.

Indeed that does work. Thanks.

So for the benefit of searchers anyone using a Vaio Z600/Z505 who has a 
problem where there LCD doesn't power up after S3 suspend. Try adding the 
parameters "acpi_sleep=s3_bios acpi_sleep=s3_mode.

RE: Z600 screen restore

[Pallipadi, Venkatesh]

This is probably the acpid shutting down the system after successful
wakeup.
As it thinks the button event was for shut down.

Check whether you have acpid installed.
Check the acpid config file, whether it has anything like this.
	event=button/power.*
	action=/sbin/shutdown -h now

Comment it if it is there and try again.

Thanks,
Venki

No no acpid running.

Also.. the machine isn't shutting down... it's running just fine. I can type 
commands... it's just that the screen isn't powered up... and commenting 
those lines out 'fixes' the problem.
