Hello everyone

i am using Fedora 14 in my Toshiba satellite pro c650
configuration is processor:c2d and intel hd graphics mother board

problem is it doesn't work unless the "acpi" option is made "off"

which in turn treats the laptop as a dektop it doen't show the battery power management and the audio input and output ports do not work so please kindly help me how to resolve this problem

acpi=off is somewhat like using a sledgehammer to drive in a nail. Try other options like nolapic and noapic first.

May want to look at what kernel you are using... Had the same problem with Toshiba (they are known for being difficult on the ACPI side) and had no ACPI support on it until a few days ago when I was testing Linux Mint 11. I forgot to edit the options and add acpi=off and the system booted and had from what I can tell full support for acpi. UNAME -a output is as follows if you need it:
2.6.38-10-generic #46-Ubuntu SMP Tue Jun 28 15:07:17 UTC 2011 x86_64 x86_64 x86_64 GNU/Linux.

Hope this helps. I know how frustrating it can be, I was about to ditch the laptop as I won't have a laptop that can't run Linux.

Well Hello "muchristian"

I am a Linux Lover .And I am a newbie.So, I would be delighted if you could elaborate Yor Reply .

And basically i am fedora lover. That's why i didn't switch over to other flavours

of course , i tried but only fedora did let me in.others didn't even started .

I used Linux on my Desktop Just As a Normal normal User.

I am Just Started Into it .

Rakesh,
Am I to assume you have Fedora installed on the system? If so, I am also assuming you are booting it with the option acpi=off. Would you mind providing the kernel version you are using? If you don't know how to get that information easily you can simply run the command "uname -a" minus the quotes. I really don't have any reason to believe that it is a particular version of Linux that is providing the ACPI support for my toshiba, I think it is solely related to the kernel support. As I mentioned in my post I am using Kernel 2.6.38-10-generic for AMD64 bit processors. Please post the kernel version you are running and maybe we can work from there.

Is there any reason you haven't tested using Fedora 15?

@muchristian

Well I will Soon Get to it friend....

i have installed fedora 14 and i am using linux since past 1 year

i didn,t still tried fedora 15

will soon to get to you

This is what i got in fedora 14 for uname -a:

Linux Monk 2.6.35.6-45.fc14.i686 #1 SMP Mon Oct 18 23:56:17 UTC 2010 i686 i686 i386 GNU/Linux


even when i booted with fedora 15 installation dvd i got bios handoff failed in bios bug while loading the dvd for installation

@rakesh.palaparthi
From what you posted it seems to me like you received a different error when trying to boot from the Fedora 15 DVD. Have you tried booting from that DVD using some of the options that TobiSGD mentioned above? I know you mentioned that you are new to Linux, but I think it might be a good idea to boot in to your current Linux installation (fedora 14) the way you do it now using the acpi=off option and then use the software manager to update the Kernel to the latest that is available in Fedora. Once that is updated you should try to reboot the system without the acpi=off. I really think that your upgrade of the kernel will fix your problem.If you take a look at: http://www.linlap.com/wiki/toshiba+satellite+pro+c650
"ACPI does not work properly with kernels older than 2.6.36 so you will have problems with wireless and other aspects."
according to that site you can simply apply a patch to your current kernel. Pay attention to the comments below the instructions. Looks like there may be some issues with sound after the kernel upgrade/application of a kernel patch, but upgrading ALSA drivers seems to fix it for some people. Post back your results and we can go from there.

Good Luck!

Well

Hip Hip Hurray.............................

The Problem is solved with kernel versions greater than 2.36.x

I have Downloaded from kernel 3.01 latest compiled and installed it.

The problem acpi is done everything is working perfect...

@muchristian : Well I forgot to mention that i am new to Linux in the context of programming kernel details

And i am using linux since past year and 3 months

Good to know that you have solved your problem. Please mark this thread as solved.

rakesh.palaparthi,
Congrats, Glad you were able to get that up and running!

To My Surprise

Fedora 15 Has Made GNOME 3.0 The Default Interface......

It's Really A great Step ...

And Think What Gnome 3.0 is good ..

Gnome 2.x User After A Glance At it Will Be Frustruated ..ONly A n hour R more Surfing In It Will Make Him Smile... And So For Me..

But It's Still In An Imature Stage
