Re: Fan never stops DSDT / BIOS hacking thread

hi lemach,

as we moderators are volunteer here and not working for lenovo. so, we cannot give you any information about upcoming updates.

about your issue, can you check if the issue persists on safe mode and/or if you can, try to boot-up your computer with linux to check if it's driver or windows issue ( no need to install linux )

Re: Fan never stops DSDT / BIOS hacking thread

lemach, do not expect a quick solution. i have had this problem for 8 months now and still no update or patch - nothing. right now i am at local library, everything is quiet, but my laptop is noisy as usual... love it.

 

and lenovo: thanks for your great customer care. (irony of course)

Re: Fan never stops DSDT / BIOS hacking thread

[ Edited ]

who have reported the problem to the mods by PM as requested in other posts ? I reported my case twice and didnt get feedback yet ...

 

One workaround for powerusers is to load fixed BIOS DSDT using grub for booting OS , easybcd if using windows , else use patched kernel on linux , ask me for latest version ...

Re: Fan never stops DSDT / BIOS hacking thread

Hi rzr,

 

I don't have a windows OS on the laptop - and I don't know if you can override the DSDT before booting windows.

 

With grub2 it's simple to insert a custom DSDT file on boot. I found a good reference post at http://blog.michael.kuron-germany.de/2011/03/patching-dsdt-in-recent-linux-kernels-without-recompili...

 

I didn't use the 01_acpi.txt he provides - even though that's probably the easiest way of doing it.

 

I took a chunk  of /boot/grub/grub.cfg and copied it to /etc/grub.d/11_acpi:

 

menuentry 'Ubuntu, with Linux 3.0.0-12-generic' --class ubuntu --class gnu-linux --class gnu --class os {

recordfail
set gfxpayload=$linux_gfx_mode
insmod gzio
insmod part_msdos
insmod ext2
set root='(hd0,msdos1)'
search --no-floppy --fs-uuid --set=root ff5bc546-589b-42f4-a9d3-048348c9eba8
linux /boot/vmlinuz-3.0.0-12-generic root=UUID=ff5bc546-589b-42f4-a9d3-048348c9eba8 ro quiet splash vt.handoff=7
initrd /boot/initrd.img-3.0.0-12-generic

}

 

added in the shell script bit at the start:

 

#!/bin/sh -e

echo "Adding entry with custom dsdt.aml loaded"

cat << EOF

menuentry 'Ubuntu, with Linux 3.0.0-12-generic' --class ubuntu --class gnu-linux --class gnu --class os {

recordfail
set gfxpayload=$linux_gfx_mode
insmod gzio
insmod part_msdos
insmod ext2
set root='(hd0,msdos1)'
search --no-floppy --fs-uuid --set=root ff5bc546-589b-42f4-a9d3-048348c9eba8
linux /boot/vmlinuz-3.0.0-12-generic root=UUID=ff5bc546-589b-42f4-a9d3-048348c9eba8 ro quiet splash vt.handoff=7
initrd /boot/initrd.img-3.0.0-12-generic

}

 

and added the acpi call at the end:

 

#!/bin/sh -e

echo "Adding entry with custom dsdt.aml loaded"

cat << EOF

menuentry 'Ubuntu, with Linux 3.0.0-12-generic' --class ubuntu --class gnu-linux --class gnu --class os {

recordfail
set gfxpayload=$linux_gfx_mode
insmod gzio
insmod part_msdos
insmod ext2
set root='(hd0,msdos1)'
search --no-floppy --fs-uuid --set=root ff5bc546-589b-42f4-a9d3-048348c9eba8
linux /boot/vmlinuz-3.0.0-12-generic root=UUID=ff5bc546-589b-42f4-a9d3-048348c9eba8 ro quiet splash vt.handoff=7
initrd /boot/initrd.img-3.0.0-12-generic

acpi /boot/dsdt.aml

}

 

where /boot/dsdt.aml is my fixed dsdt.aml explained in earlier posts.

 

Made this exexutable (chmod +x), then ran update-grub or update-grub2 (not sure which?) then to add these to the grub boot menu.

 

Probably better explained by the man himself mr dedoimedo

Re: Fan never stops DSDT / BIOS hacking thread

patching windows7's kernel is illegal i suppose, but my suggestion was to use a bootloader that will load , inject and replace the BIOS's DSDT before booting the OS of your choice  but I am not famillar with ms product and dont really care ...

the MacOSX hackintosh guys are using those kind of tricks but I fear this is not a job for a regular user ...

 

So as any of you tried to call / contact lenovo for support ? please report ...
