brightness osd not working

i updated the intel graphics driver to the intel one and now there is no brightness osd. the reason i upgraded to the intel one was tha tthe lenovo ones were giving me problems. is there any way to get the osd function back. the osd of the other functions are still working as far as i know. anyone have any ideas?

 

What model and operating system you're using? Can you give details of the problem you had on the Lenovo Intel drivers?

 

it's an x201. the problem with the lenovo driver was that sometimes the when i hover my mouse over the taskbar to use preview or run my mouse over the alt tab window, it would give me a short freeze of about 1 second. i am just trying the intel driver for now to see if it fixes the problem.

also about how often does lenovo release updated drivers of crucial components such as mouse drivers, graphics drivers, etc.?

 

I had this same problem on my x200 when I did a clean install upgrade to Windows 7. The solution was to install an older Intel video driver for the 4500 GPU. Once I did this, the brightness OSD started working again.

The most recent driver is version 8.15.10.2057 (7xd652ww.exe). The older one I installed was 8.15.10.1855 (7xd808ww.exe). Unfortunately, I can't find the download link I used to get the older driver. I remember it being somewhere on this forum.

 

but the one i am currently using is from intel themselves and not downloaded from lenovo which i think is why i don't have the brightness OSD. the one from intel is a newer version according to the revision number. if i were to download the one from lenovo then i will have that brief freezing problem but the brightness OSD would work.

 

The OSD does not work for me either. I think the OSD is a lenovo driver feature only so the only possible way for us to get OSD is if we download the driver off the lenovo site.
You can get the 2 step brightness control in the registry from the lenovo driver. For the intel drivers, I was only given ~7 different levels of brightness but for the lenovo drivers I was given 15.
Does anyone else have this problem? Whenever I resume from standby, I cannot use the fn+home/end key to increase/decrease the brightness level. To fix this, I have to reboot my notebook

 

i still get 15 levels just no display so i have to count it myself lol.

 

Lenovo modifies the original display drivers made by Intel so that it can implement its own technologies such as the OSD. Unfortunately you won't be able to use that feature using the official Intel drivers alone even though it is newer. Same is true with any OEM drivers such as Dell or HP.

Kevinf, I don’t think you’re the only person who has this stuttering problem on their X201 as others on this forum have also noted this problem. Did the official Intel drivers work out better for you in the end? I don’t have an X201 at the moment to test this theory (though I am getting an X201t soon), but I would experiment by combining certain files from the Lenovo and Intel drivers to see if that works. I let you know once I receive it so that I can test it out.

 

so far i haven't experienced the problem yet but it doesn't happen very often though. i can probably give a conclusion after a week of use. the last laptop that i used didn't have osd for brightness either so i think i can live with it. what other features would i lose by going with the official intel drivers? so far i haven't noticed anything else different besides the osd

 

I can't confirm whether this is true for the X201 but my sister has a R61e using Intel official drivers. Waking up the laptop from sleep mode occasionally make the screen garbled so I don't think the power management settings are implemented properly on the Intel driver in comparison to the Lenovo modified driver. Other than that I don't think you're missing much from the OEM driver.

 

I upgraded a while back to the Intel supplied drivers on my T410 and it fixed my 'final' T410 issue which was a periodic crash (BSOD) while the PC was sleeping.

Every 2-3 weeks I'd switch on my laptop to have it power on from scratch rather than wake. The 'Problems and Solutions' had always showed the Intel driver as the problem which is why I forced the upgrade.

The Intel drivers have garbled the display once, but otherwise worked perfectly, other than the mentioned missing brightness OSD.

I would love an official upgrade to the latest from Lenovo as the video BIOS has not been upgraded when just loading the drivers.
