The Definitive Guide to Acer Aspire Gemstone Blue Throttling Issues

[moral hazard]

You have to download the microsoft asl compiler use it to load the aml file.

If you look a few pages back you will see a guide.

Basically use the command:
asl /loadtable dsdt.aml

Do you see the following during throttling?

@weinter
I checked the event viewer logs, I don't have it there.
But I'm 100% sure this is throttling.
Have you taken a look at my DSDT? I posted it on page 39.
Thanks!

This is what I see in event viewer related to Kernel-Processor-Power, which is only information on the states. There are 8 throttle states according to this.

[Feoras]

No, I didn't see this in my event viewer.

@moral hazard
I remember you helping other people on another thread with a different laptop model on modifying the trip point for the throttling. If you can, would you please have a look at the DSDT table I attached on page 39 as well?
Thanks!

Although, I re-read the thread from the start again, and see that so far, there is no-one yet who has eliminated throttling with editing DSDT. Is it possible the ACER bios override the DSDT? Then we won't be able to fix it this way. I hope not! Or maybe there's another part on the DSDT that we are missing to edit.

Weinter, please thumbnail your image - it's too big for the page.

I looked at your file, I dont think I can help.
I can only do what Weinter does.

We already tried many things and none of them worked.

On the other thread, they had a nice notebook that responded well to the changes. But your notebook is strange, it manages to throttle no matter what.

I can maybe try a few more things for you.
1. Set the trip point to a larger number (150C).
2. delete the passive cooling list.
3. delete the temp sampling period so that the temp will never change.
4. Set the temp to always be = 20C
5. Cap the temp at 50C.

Let me know if you want me to give you the modified files.

If we delete the passive cooling list it means the fan will always be on? Actually, I'm looking for a way to make the fan always run at full speed.

I know this doesn't make sense to some people, but I believe this machine is really capable of good gaming if not for this throttling problem.

If we undervolt plus make sure everything's cool and run the fan full speed always, hopefully, it will be always below the threshold. Right now the fan only spins fast when the CPU is already hot and is about to throttle.

There's still a chance it will throttle but so far setting the temperatures in the DSDT doesn't seem to work, so why not look for 'more prevention' rather than a cure?

Can we set the fan to run full speed always in the DSDT? Don't really care about battery.

Thanks moral hazard and weinter and everyone for all your continuing efforts on this!

[moral hazard]

yes you have fan code in your dsdt code. Should be possible to set the speed.

Let me think a bit.

[moral hazard]

PowerResource(FN00, 0x0, 0x0)
        {
            Method(_STA, 0x0, Serialized)
            {
                If(LEqual(DTSF, Zero))
                {
                    Return(Zero)
                }
                Else
                {
                    Return(One)
                }
            }
            Method(_ON_, 0x0, Serialized)
            {
            }
            Method(_OFF, 0x0, Serialized)
            {
            }
        }
        Device(FAN0)
        {
            Name(_HID, 0xb0cd041)
            Name(_UID, Zero)
            Name(_PR0, Package(0x1)
            {
                FN00
            })
        }

So I might modify this part and see if it works, will you test the code?
