(X200s)Windows 7 cannot remember my screen brightness setting?

Hi all.
I just installed windows 7 x64 on my X200s, but encountered an annoying issue.
I also installed the new Thinkpad power manager 3.05, and created my own power plan. However, no matter how I changed the lightness setting and applied the changes, after a restart or log off/log in, it was reset to default values, which are 1 when using battery and 6 when plugged in.

Did I miss something? Or is this an expected behavior?
I don't feel very comfortable anyway...

By the way, I noticed that in Windows 7, the lowest brightness level is much brighter than it was in Windows XP. How weird....

 

Did you install the power manager driver, hotkey driver, and osd drivers? Need more than just Power Manager for it to function properly. If not, uninstall power manager, install hotkey, osd, power manager driver then power manager. Order matters. Look at clean install guides on this forum. It will give you a good idea of what to do.

 

I had the same problem. Try to install the last driver for the Intel graphic card from Lenovo, it should solve this.

 

Thanks for your fast reply

Yes, yes and yes, I installed everything I can dig from lenovo's website.

Hey, I recalled one more strange thing: the OSDs, including volume control/mute/keyboard light, work just fine, except for the brightness meter -- it just doesn't show up. Not a big deal, but maybe this is related to my issue

Hi, did you get your problem solved?
Can you provide driver's version?
Thanks.

 

Yes solved it after a clean install yesterday. Now that I think about it, maybe the updated chipset driver helped too. Anyway I used the updated windows 7 drivers available there :

Lenovo Drivers for X200s

Have fun

 

Oh, didn't know that the drivers are available from the English lenovo/ibm site now.
I downloaded all the files yesterday from Chinese site instead.
Thanks for your information. I will have a try tonight

 

Same exact thing is happening to me. I have a T400 (integrated graphics) running Windows 7 Pro 64 bit.

And I agree that the minimum brightness on Windows 7 is way brighter than it was on XP, and the max brightness on 7 is dimmer than it was on XP.

 

Problems all solved!!

Thanks to frenchbat, new display driver is exactly the key to these problems.
Now my brightness settings can be saved successfully, AND the brightness meter is back. Perfect!
AND, now the minimum brightness gets lower than before, nearly the same to XP.

Note that the driver's installer may claim that the current driver is newer. Just ignore it

 

Will that work for me? I'm on a T400, not X200s.

 

I have this same exact problem with my X200s.
I will be installing a fresh version of win7 64-bit and following frenchbat said (downloading drivers here).

 

@Kuzuryuusen and X200s
Glad it worked for you as well guys. Enjoy

In your case, I don't know if the new Intel driver alone is gonna make the trick. Do you have the hybrid gfx ? In any case you should look for updated drivers at Lenovo. Did you check in the sticky thread above, "Windows 7 Experience and Drivers", to see if anyone has the same problem ?

EDIT : Seen in your other thread that it's solved. Good then.
