Thinkpads Forum

I am not sure on the causality on this. However, since I installed Win 7 x64, my X61 (7673-CTO 2ghz 2gb-ram) is getting very warm (40-55 celsius) (especially around fingerprint reader and wlan). The second fan is always running, and gets a bit annoying from time to time (when just idle or surfing with wlan off and no CPU load...). I have removed the modem chipset, and turned down the Wlan effect, but still it's a lot warmer and nosier on Win 7 x64 vs XP.

The other issues i have experienced deals with power and unexpected freezes. I have all new drivers that i have found, and all updates for Win 7.

If i use my Thinkbase without battery, then it happens that the notebook stalls, sometimes it is vomiting ugly noise through the speakers. This has happened even without the thinkbase, but not as frequent (never occurs if battery is installed).

I cant find any information about this, would appreciate if someone could point me right, or have had similar issues.

i run Windows Professional 32 bit on both an X61 and an X61s. I regularly download all updates available through Windows update and i installed most of the utilities offered by Lenovo System Update. i have not experienced any freezes or abnormal noise of any kind. the 32 bit version works great on these machines.

as far as heat goes, i have noticed that Windows 7 Professional 32 bit runs a little hotter on my T60 14" than Vista 32 bit - the x1400 GPU runs maybe 5-7 degrees C hotter. i now use TPFanControl to force the fan to turn on more often and keep my GPU below 60 degrees while docked. i never paid any attention to temps on the X61/X61s before, so can't comment on those.

you might want to play with some of the options in power manager. sorry i can't help...

How long you have been running Windows 7 installation? As far as I know the high CPU load and temperature may be caused by Windows 7 indexing and optimizing services running. According to my experience Windows 7 (and the same goes for Vista) runs hot at the beginning while it is indexing all your stuff. As soon as the job is done everything should be back to normal. If you do not need your files indexed I suppose that you can solve the problem just by disabling the relevant services. And I do not think that this is somehow 64-bit related. I run both versions on two different machines and they behave quite similar in this regard.
As for other issues you have mentioned I do not know what to say.
Hope this helps.

Thanks for the replies!

I have since yesterday, had three freezes (now even with battery connected!). I filmed the behavior but my frakking compact-cam did not record it properly. But I will be able to post a video later on.. However it froze while i was sleeping, and it actually rebooted afterwards. However windows never manages to create any kind of useful information in the logs, thats makes everything a bit annoying really..

I have tried to play with the Power managment settings, but with no success. It seems that the CPU is clocked to maximum (2-ghz) even when idle. But not sure if the information from the "system control panel" is right (right click "computer" icon, choose properties).

I have been running Win 7 since approx three months now. So there should not really be any indexing processes that loads the CPU...

Thanks for your bother

I put Windows 7 Pro 64-bit on my T61p (previously running Vista Business 64-bit) and both the core CPU temperature and the GPU temperature are the same in Windows 7 as for Vista. And in both cases, cool.

So I would say it may be something different in your Windows 7 installation. .... JDH

Great to know JDH!

It would seem that something is wrong with my Windows install. Tried to stress it in safe mode, but did not manage to replicate the crash problem.
However, I have managed to make a video of the symptoms!

I will try to remove all drivers and software, and install only the newest and hope that it will make a difference.

Thanks

Just want to give a notice. The issues with freezes and other issues I experienced, was due to a software from the "Voddler" service (Video streaming thingy). When uninstalled everything went back to normal, and similar issues have been reported on other systems.

Good to know, will never try to use that service again.

Thanks for your help and feedback!

wow, not good to hear but good to hear it worked out.
