    Re: HOWTO Fix A Buggy DSDT File

    Hello,

    I have a new Dell M5010 (with newest A10 BIOS, AMD P360), and I have a problem. It's overheating (70 °C at boot, 75 °C at work, the service say's OK, but Dell it's not...).
    I want to edit DSDT, but it doesn't have Thermal Zone and I got many error during recompline...

    Can somebody help me?

    Re: HOWTO Fix A Buggy DSDT File

    I've been working on fixing the Compaq Presario CQ61 DSDT since I discovered that the fan spins slow all the time and the laptop overheats.

    I have managed to fix it and now it compiles without any errors.

    Everything works as expected, the fan speeds up when the load gets hight, but It is still running a little bit hot. I am willing to trade some noise for a few degrees down, and I am trying to figure out where in the DSDT can I control the fan speed? I have been looking into it for a long time and I still cannot figure it out...

    Any help would be greatly appreciated

    Re: HOWTO Fix A Buggy DSDT File

    Laptop: HP Pavilion dv6 6008el (2Ghz Intel Core i7 2630QM, 8Gb DDR3, Radeon HD 6490 1Gb, 500Gb sata 7200rpm).

    My laptop doesn't boot - blank screen - if acpi=off is not specified in grub, that way disabling ACPI entirely (unacceptable). Ubuntu 10.04 LTS and 10.10 aren't affected, Natty 11.04 is. I followed debug instructions on LessWatts and discovered DSDT table is broken, please help!

    HTML Code:
    DSDT.dsl    37:     External (\TNOT)
    Error    4057 -                   ^ Name already exists in scope (\TNOT)

    Re: HOWTO Fix A Buggy DSDT File

    For my DSDT file, when recompiling, at first I get a series of error like this:

    Code:
    dsdt.dsl  8236:                             Name (_PLD, Buffer (0x10)
    Error    4080 -              Invalid object type for reserved name ^  (found BUFFER, requires Package)
    I changed s/Buffer/Package/ in each line and the Errors are gone.

    All that remains are these Warnings:

    Re: HOWTO Fix A Buggy DSDT File

    Hello i tried to copy the dsdt file to my home folder but there is no such file in /proc/acpi/ do you know what i could do?

    EDIT: i think that it is now located in folder /sys/firmware/acpi/tables/ is that correct?

    Re: HOWTO Fix A Buggy DSDT File

    i have a Pentium M 760 Dothan C0 2.00 GHz and motherboard has ACPI 1.0

    cpu scaling is broken with natty and oneiric likely due to the kernel devs no longer supporting kernel hacks and choosing to go for the safer acpi option.

    is it possible to hack the DSDT to get cpufreq working again.
    currently i'm stuck with p4-clockmod and 1.5GHz.

    Re: HOWTO Fix A Buggy DSDT File

    Hello experts,

    I have an HP Envy 14T-2000 (Beatsaudio) and have extracted it's dsdt. When I try to compile it I get the following error and warnings:

    19 Error Name already exists in scope (\TNOT)
    2316 Remark Initializer list shorter than declared package length
    4520 Warning Not all control paths return a value (_HID)
    4520 Warning Reserved method must return a value (Integer/String required for _HID)
    4579 Warning Not all control paths return a value (_CID)
    4579 Warning Reserved method must return a value (Integer/String/Package required for _CID)
    5052 Warning Not all control paths return a value (_BST)
    14218 Warning Not all control paths return a value (_CRS)
    14218 Warning Reserved method must return a value (Buffer required for _CRS)

    Can you please help fix the above errors so I can compile and use it on my Ubuntu 11.04 installation?

    I have attached the DSDT file for easy reference.

    Thank you.

    Used my dsdt editor to try and automatically repair the 124 errors,

    1 Error left 1 or 2 warnings and 1 remark I think... though much improved on the original... Give it a whirl

    (that's about my limit)
