Lenovo Thinkpad X250: can't adjust brightness

Q: Lenovo Thinkpad X250: can't adjust brightness

Hi, I can't adjust the screen brightness on my X250 at all. I have Windows 7 on it. When I press + and - the slider thing shows up, and it goes up and down, but nothing happens. It's really bright and have already been like this for weeks. The colour is slightly wrong as well. Restarting, shutting down or closing and opening the lid does nothing.It got stuck after I disconnected it from my docking station, so I tried connecting it and disconnecting again - nothing. I've updated Windows and nothing there as well. I'm getting really frustrated since nothing works.. Is there something to do? Please help..

Thank you forum! Much gratitude here for your selfless service!!

I am not very tech savvy but I am usually able to solve my own problems. My cat jumped on my keyboard, my display went dim and I could not adjust it ! I am able to move the brightness bar up and down but nothing happens. First, I tried a system restore but that did not work. I went back about a month which was the earliest restore point I had. Then I went to device driver and looked to see if my driver was functioning properly. I was told it was updated and functioning properly. I tried clicking on the windows generic monitor driver also as advised which did nothing. I went to the device driver on the pc and updated from that which also did not work. I am using windows 10.

So i have a X250 with both internal and external batteries, i recentley upgraded the bios to version 1.27 and reinstalled my machine from scratch. This is when i noticed that it uses the internal battery first, and then immidiately powers off instead of using the external one. I haven't found anywhere in the bios that i can set the priority of the batteries but shouldn't it be the other way around by default?  Any help is greatly appreciated

A:Lenovo ThinkPad X250 Battery Priority

I switched batteries a minute ago an now it uses the external one first, and refuses to use my 45N1777 battery alltogether. Would a bios-update really make my machine unable to use that particular battery? Seems odd in my mind.

Using the laptop on battery, when I press on F11-12, the brightness meter is shown on the upper left like usual, but it won't move up or down.  Yet I think it's strange that all other places I can adjust brightness are fine, and especially strange that everything is working totally fine on AC power.
I tried uninstalling the Generic PnP monitor and reinstalling, but to no results.  Also, both my power settings on battery and on power indicate no adaptive brightness.

Hello there, I need help please! I can't fix the screen brightness. It appears to be stuck on full brightness which draws my battery life quickly and hurts my eyes during nights. The brightness button in the action center is missing, there is no brightness slide bar in the display setting nor in control panel, and brightness fn buttons in the keyboard are not working as well. When I click on the battery icon, there is a brightness button next to the battery saver button but also not working (not even clickable).I searched online and I tried:- updating/reinstalling/rolling back display drivers- resetting pc (reinstalling windows)- many other little repairs College is starting soon and I really need my battery life and I will be studying on my laptop in late hours so this brightness issue is a big trouble for me

My screen brightness using FN+F11/F12 and also in the advanced power settings slider won't adjust the screen to anything other than brightness and minimum or brightness to 100% when I move the slider.  It shows the percentage moving up and down, but the screen stays 100% until I'm on the lowest setting,  then it goes right to minimum.  I received a bunch of Lenovo updates on the first Wednesday of this month and I've had several issues since then, I tried reverting back to previous drivers, but it made no difference, so I'm back on the latest drivers.

Beginning today, I opened my laptop from sleep and noticed the display was at its lowest brightness setting. I then tried to restart it to see if that would solve it, no luck. I did some googling and found out it could be a problem with the graphics driver. I then disabled it and enabled it. Now the brightness is at its max settings.

The function (FN) + F4, F5 (the keys to adjust the brightness settings) do nothing. The brightness status will show up on the screen and only change 1 or 2 notches.

I then realized I should have a way to adjust the brightness via the Power Settings in the Control Panel. I even confirmed this with a friend. I should have the sliders to adjust the brightness but I do not. It's very strange.

This is the screenshot from my friend:

I have looked long and hard at other peoples' solutions to this problem to no success. I have tried:-installing latest Intel HD 5500 driver from Lenovo site.-installing latest beta driver from Intel-enabllng the Generic PnP Display-Several registry hacks that claimed to work (I reverted back after they failed to do anything) My question is, when will the display driver support brightness settings again, or is there an older version that works that I can download? I can't "roll-back" my display driver, as the current one was the first I used. Using the default Microsoft VGA driver is a non-starter. I need proper resolution. If anyone can help, I would appreciate it. I feel like I have tried every solution on the internet, and perhaps the only solution for me is a different driver, possibly.

Ok I've had vista for a long time, but I switched over to XP and everything is perfect except from one small detail that is kinda big for me. I can't adjust the brightness in my laptopIn vista all I did was press fn left/right arrows to adjust it. And from what I know this is the way you do it in most laptopsNow in this XP I had to install all drivers. Specifically from this page http://www.laptop-software.com/acer-softwa...5738zg-drivers/when I install the graphics driver, VGA intel driver for vista is the one that's used for my computer from that list, the brightness just goes to the max apparently and I can't use fn arrows to adjust it. I CAN use fn arrows up and down to adjust the volume so there is definitely something fishy here. If I uninstall the driver I can use fn to adjust the brightness normally so I know the problem is when I install the driverthis brightness is driving me crazy! the driver bring something called Intel Graphic Media Accelerator which has an option for brightness, but it seems as if that's a different type of brightness cause it just makes the screen duller. You can actually still see a lot of brightness coming out from the computer but the screen is very dull. And it still damages my eyesany help?

Hi: If the brightness is stuck on maximum, you probably need to install the graphics driver. The problem is that HP only supports that model for W10. See if this W8.1 graphics driver works... This package provides the AMD High-Definition (HD) Graphics Driver and Catalyst Control Center for supported notebook models that are running a supported operating system. For notebooks with switchable graphics modes, this package includes drivers for both graphics processing units (GPUs). Switchable graphics enable users to switch between a power-saving graphics mode (normally used under battery power) and a high-performance graphics mode. If high-definition multimedia interface (HDMI) video output is supported, this package also installs the HDMI Audio Driver. http://ftp.hp.com/pub/softpaq/sp72501-73000/sp72773.exe

It says windows cannot adjust brightness on this computer. I tried the various locations where the brightness slider may be but all the relevant screens show no brightness slider.

I don't know whether win 8 had the brightness control before upgrading to 8.1 ( I mention this because several people complain that after upgrading to 8.1 , they loss brightness control amd regained it by rolling back the driver )

I tried the update driver option but it says my driver is already updated. The roll back option is greyed out

How can I adjust the display brightness in XP? On battery power, the display automatically dims. I want the display to stay at a constant brightness when on battery or on AC power.

When plugged in, my aging laptop's LCD brightens, however it seems as if the power supply cannot handle the increased load, so there is a very annoying flicker; it gets dim, then bright, over and over. Could this be an inverter problem or the backlight or the power supply, or any combination. This is an HP, for anyone has any experience with HP laptops.

I'm not sure if this is in the right forum. But in the last couple months, once in a blue moon I couldn't change my screen brightness, and now in the last couple days it's gotten a whole lot worse. Usually, I can't change brightness either via my 'fn -/+' hotkeys or via the actual brightness slider in the power panel. A full reboot or simple hibernation then reboot both let me change brightness again. But the last couple days, restarting the computer just puts the brightness on either fully dimmed or fully bright, and I still can't change it.

This is an HP G60 laptop, and I've had windows seven for a year on it. Like I said above it only started a couple months ago then got worse this week, and what I've found on google so far was all for newly-updated-to-seven issues. My drivers all seem to be up to date according to the windows update driver function... Can anyone help me?

since a reboot fixes it (at least temp.) it is probably not hardware but software. Do you have a backup from before the problem started getting worse?

Do you have the win 7 dvd to do a repair install?

Hello everyone, I just yesterday received my T450 and in general I am really happy.What drives me a little crazy is, that I cannot adjust Brightness. I'd be really happy, if someone could help. The system:T450Windows 10 <-- cleaninstalledAll Drivers up to date (thinkvantage-thingy says so)---------------- The Problem:Cannot adjust brightness via FN + F5/F6Cannot adjust brightness in the energysaving optionsSwitching between energysaving mode and normal mode doesnt affect brightnessCan adjust brightness with the Intel HD Graphic tool, but it looks weird. ---------------What i tried:-Updated BIOS- deleted Intel drivers and loaded the newest one from lenovo homepage- deleted pnp-monitor and reinstall- deactive/activate pnp-monitor This annoys me kind of hardcore. I travel 4 hours at 3 days a week. I bought this notebook to use it in this time. Adjusting brightness kind of is key in a train. So safe me and earn everlasting love!
