Hi All,

I recently got a T430. Planning to install either SL 6.3 or CentOS 6.3 on it.

Is there anyone here who has installed it?

A couple days ago, noticed a sharp hike in temperature and battery usage after installing Ubuntu 12.04. So got scared and went back to Windows 7. Will it be the same with SL 6.3 ? I dont want to fry this guy. It cost me a lot of money and I intend to use it for a long time to come.


I now need to familiarize myself with a Redhat Clone, so thinking to go for SL 6.3 or CentOS 6.3


Any experience will be very appreciated.

I know I can go the VMWare way, but, need to get off the Windows 7. Tired of the crashes. Tired of the viruses and I really feel that a thinkpad deserves a better OS. http://dl.dropbox.com/u/2835777/BangHead1.gif

Please help me folks.

To some degree... yes, it will be the same. My limited understanding is that Linux kernels were not exactly stellar at power management until fairly recently. I don't know the exact kernel versions in each distro but unless they are very new you'll likely see longer battery life and lower temps in Windows 7.

I have Ubuntu 12.10 and Windows 7 Pro running on a T530... Lenovo includes some pretty nice applets in Win 7 for managing the power profiles from eaking out the last drops of battery life to manually boosting the fan speeds to keep temps down during cpu/gpu intensive operations.

There are some indicator applets that work under Ubuntu's Unity that allow reasonable configuration of the power management profiles from the top frame/bar (sorry, I don't recall all the 'correct' terms for all the widgets of every desktop environment I bounce between...), and powertop will let you see what is using power, including toggling a few settings... but the short version is that laptop power management on Linux in general lags behind other OSs like Windows or Mac. Can you get acceptable life out of it... probably.

Also... I've never really ran anything under Linux that really drives the temps screaming up like I do on Win7 (games w/ serious 3D rendering), so temps haven't been a major concern for me. That said... I've never really tried very hard to manually control the fan speed(s) under Linux - the equivalent of going into the Lenovo/IBM power management app under Win7 and toggling 'Graphics Boost', which is what keeps the temps down to a reasonable level (and noticeably increases the audible noise of the fans).

FWIW... there are supposed to be some ThinkPad related things rolled into openSuSE, as SuSE & IBM have in the past shared a slightly closer relationship. I just get frustrated with certain things on that distro, no matter how much I like other bits of it.

Take a look at lesswatts.org for some more Linux power management info/tips.

Lenovo has a forum specifically for Linux here:

And a Linux Knowledgebase here:

And a Linux/ThinkPad wiki here...

Hi,

We run fedora on all of our laptops because they have the latest drivers and kernels and tend to work better. Even the built in web cams.

I'd start with F17 and once you get that straight you can use fedup to upgrade to F18.

We use the crap out of our laptops and have never had issues with heat or cpu utilization, battery life seems to meet the oem's specs. We run t5xx series lenovo laptops.

You can also use the latest Linux kernels on RHEL (and clones) by installing them from ELRepo.

Hi,
i'd give a try with SL 6.x. The power management is good and compared to Fedora, this is stable distribution with 3 year life-cycle.

I personally use on my laptop 'tuned-adm' command to manage my profiles.

try:
CODE

[root@orionis ~]# tuned-adm list
Available profiles:
- throughput-performance
- server-powersave
- latency-performance
- desktop-powersave
- laptop-battery-powersave
- spindown-disk
- virtual-guest
- default
- enterprise-storage
- virtual-host
- laptop-ac-powersave
Current active profile: laptop-battery-powersave


to change profile:

CODE

[root@orionis ~]# tuned-adm profile laptop-ac-powersave
Reverting to saved sysctl settings:                        [  OK  ]
Calling '/etc/ktune.d/tunedadm.sh stop': wlan0     no private ioctls.

                                                          [  OK  ]
Stopping tuned:                                            [  OK  ]
Switching to profile 'laptop-ac-powersave'
Applying ktune sysctl settings:
/etc/ktune.d/tunedadm.conf:                                [  OK  ]
Calling '/etc/ktune.d/tunedadm.sh start': wlan0     no private ioctls.

                                                          [  OK  ]
Applying sysctl settings from /etc/sysctl.conf
Starting tuned:                                            [  OK  ]


cheers,

Hi Helikaon and Nathan,

Thank you very much for your suggestions.

I was able to successfully install SL 6.3 on my laptop, but the heat issues got me scared so moved back to...ahem....Windows 7 sad.gif ( Indeed, I ought to dual boot Win 7 and SL, I need an RHEL Clone physically installed on my laptop (not through VM) to do some work. And I am working towards it)

I have started a separate thread for the heat issue...

Thank you once again for your help.

Which video driver you have? Open driver unfortunately usually strongly heated laptops.

Hi Crazzzy,

Thank you sir. I completely missed that point !!!

I dont have Nvidia Optimus. Just have the stock Intel Graphics.

Here's what I have.

Intel® HD Graphics 4000
Card memory 2,112.00 MB
Provider Intel Corporation
Card version 9.17.10.2843 08-21-2012


If the heating is because of incorrect video drives, please let me know how to fix this.
