English Install/Boot/Login

Hi,

After sleep (sleep to RAM), I want to recover it, but the system have no responses, just the power light is on. Then, I only can turn off the power, and restart it.

How can I check this problem? some logs?

My laptop is Acer AS4530, and os is openSUSE 11.4 x86_64, Desktop is KDE 4.6 .

Thanks!

It takes a while for a system to recover from sleep. Have you been patient?
My Win 7 box goes to sleep and it takes a while to get the session back after I press the power on button.

Sometimes I have to click a key to “wake up” the laptop - do you get a mouse cursor at all?

If not, you may have some “Power Management” issues - which in a LOT of cases get fixed by running a proprietary display driver (ATI, nVidia, etc.) instead of the OSS drivers. Are you running a specific driver? If not, what type is your graphics card?

yes, wait for a long time. But it can’t recover yet!

Yes, I used Nvidia driver. I can’t get a mouse, maybe it’s a “PM” issues, thanks!

Recovery from suspend to ram should be instantaneous.

Does your owners manual have noted documentation on recovering from sleep?

@robin_listas
It takes time for the hard drives to spin up and retrieve the suspended sesssions.

Not from suspend to ram, everything is in ram.

Yes, the disk has to spin up, because tasks have to read an write things
after so long frozen. But you should get a desktop in less than five
seconds. I do.

It is different with suspend to disk, that takes time to boot a kernel and
then load the suspended session from disk.

Sorry, I can’t understand your question.

I done some test for my laptop, it need kick the power button to recover from sleep to ram.

Just kick a key of keyboard, sometimes, it cann’t recover.

Thanks everyone!
