Lenovo ThinkPad L R/SL :: Hot Keys For Monitor Brightness On SL510
Jan 11, 2010
I have very annoying problem with hot keys for adjusting monitor brightness! After last version of hot keys driver they don't work. I can't increase or decrease brightness! Pressing them down and can't change anything. And there is something more! For example I have adjusted some level from power manager and everything looks good until I don't try to manage brightness with hot keys. I doesn't matter if i want to increase or decrease brightness, it just goes to maximum level!

I just got the x120e and I already went through and fixed it auto-brightening itself. After I hit the Fn + Home and adjusted it to my preference. It was not on the charger when I did that and I was in a darker room so I had the brightness down lower. Later on in the day, I plugged it in to charge and I went to make it brighter. The brightness is not changing however. All the oher Fn + F keys are working. Just not the two for brightness. The weird thing is, I shut the computer, waited for it to enter sleep mode then opened it up again and it was really bright and I had to pretty much squint, but again the keys were not working to lower it. I closed it again and opened it and it is again dimmer. The keys still aren't working.

I have installed the latest driers and since then I am unable to change the screen brightness using function keys. I have installed multiple driver updates hence it is difficult to find out which driver is causing the issue.

I've got 2 separate but really annoying issues with my W540 20BH:
- display brightness keys not working: when waking up from Hibernation mode, sometimer (really, randomly!) the display brightness keys (Fn+F5/F6) don't work.... either if the display brightness is stuck on max, min or an intermediate level...Is there a way to shut down and restart the process which commands the Fn keys?
- audio channel commutation gets stuck. Normal behaviour of the audio configuration is:
1) speaker volume disabled, mic disabled
2) when plugging in a 4-pin headset, headset's volume is on, headset's mic is switched on; speaker volume is still disables.
3) when unplugging the headset, speakers' volume is still 0
After each boot, the audio channel is at 0, but doesn't commute to the headset when plugged in! I have to open Configuration Panel, realtek properties. With this window open, unplug and re-plug the headset. Now, the volume has its normal behaviour.
Any better way to configure audio channels and evenments, which is able to bypass realtek's manager?

So I made a mistake. I've reinstalled the OS on computers dozens of times and never quite had this issue. I have the Lenovo SL510 and tried to reinstall using the dvd drive. I entered bios and changed boot settings so the dvd drive was first and then booted it up but it went straight into windows 7 on the hard drive. I tried again, hitting f12 at startup and specifically selected the DVD drive to boot from and again it would boot directly from the hard drive ignoreing the DVD drive completely. Finally I opened the DVD drive from windows and installed over top of the old OS, planning to delete the old files once the install finished.
The install went fine, everything worked, except I didn't have internet. Turns out that the wireless adapter wasn't being recognized. I opened device manager and it was showing up under "Other Devices" as Network Controller with a yellow exclamation mark. I then proceed to track down and install the wireless drivers after connecting with an ethernet cable. I tried the intel chipset program and it would fail to install the correct driver, I tried the lenovo support program and it failed to install the driver, I manually downloaded and installed the driver and nothing happened. I tried several different wireless drivers and the result was always the same. I was working on the issue for at least 8 hours.
Finally I decided it wasn't worth the trouble, and why not reinstall again. This time I created a bootable USB drive and went through the same process, changed boot order, no result booted from hard drive, pressed f12, selected the USB drive, same result. Finally I installed the new OS image over the existing OS from the USB while the computer was on.
Installing the OS over the older OS was definitely a mistake, but it seems like the core of the problem was that the computer just wouldn't boot from anything other than the hard drive itself I didn't realize the implications that this presented and during the final install of the OS from the USB the computer restarted during installation. Of course.. the computer did not reboot from the USB which meant it simply came up black screen, the OS had already been wiped from the hard drive, but it could not boot from the USB and therefore simply comes up blackscreen.
The first thing I tried to do was reboot into BIOS, wasn't happening. When I attempted to access bios it would simply blackscreen with the power on indefinitely. I obviously tried booting and using f12 several times to try switching back and forth from USB to DVD and so on, but everything just black screened.
So....If the computer couldn't boot from USB or DVD then the only option was to boot from inside the original OS, but doing that caused a massive driver error which I couldn't resolve no matter what I did. And now I'm thinking the computer is completely lost. The only idea I have is to try using a friends computer to install an OS on to the SL510's hard drive and then resintall the hard drive into the Laptop to see if it will boot from it. I've poured over this entire forum and found lots of similar issues but no one seems to be offering any answers or solutions besides an occasional "we're looking into it" message.

My laptop was able to access the internet via my wireless internet connection just fine until a few days ago when it completely stopped working. I can't even view the wireless adapter in my hardware profile anymore. I'm able to connect wired but not wirelessly. I've reinstalled access points, but it didn't work. Nothing has changed in my setup to cause this to stop working.

I don't have a lot of money to replace the laptop that just completely died a month after the warranty expired. It is a Lenovo Thinkpad SL510, S/n xxxxxxx and the product ID is 28479XU. Purchased 3 years ago. I would like to know if I can take the hard drive out (which I was told by a knowledgeable computer person that it is OK with all the data on it) AND put it in my working Lenovo Thinkpad SL410, S/n xxxxxxx, Product ID 28427PU ?The SL510 is really dead. All efforts were tried to resusictate by same computer person.

Look' s like I have big problem:
1. When I plug charger in to my SL510 lights don't turn on. If battery are take out - laptop is impossible to turn on;
2. If I plug same charger to my second (old r60 thinkpad - lights is turning on and all boots normally);
3. I take charge from my second laptop and test on SL510 - lights still not turning on;
4. If I try to boot without charger (on battery) laptop is working fine.
Is it possible that - when my battery be empty I can never turn on my laptop?

Thinkpad SL510 operated with windows 7.
Whatever I try, I am not able to activate the WLAN card. When I diagnose the network connection it says somethink like "the device is not activated or not installed". However, the device is listed properly as "Intel WiFi Link 100 BGN" in the device manager. All windows updates are installed, and the Lenovo update manager only shows one optional update (Intel Chipset driver for Windows 7) which gives an error when trying to install it.
One strange thing is that, when I use the "ping 127.0.0.1" command in the command shell, only 1-2 out of the 4 tries give a result, the other ones show a timeout error.
What is more, the device works properly with an Linux Live disk, so the hardware seems to be ok. It is just not working with windows 7.

I had 1GB & 2GB rams working fine in the SL510, windows 7 Profession, 62-bit, 320 GB drive. SL510 62-bit can take up to 8GB ram.
I replaced the 1GB by Samsung with a Hynix 4GB. At Crucial they give specs that are replacable for existing ram. I notice one number is different. The original Samsung says PC3 -10600, and the new Hynix says PC3-12800. The 12800 was given by crucial as part of the replacement numbers for the SL510. I bought at EBay used.
Anyway, I bootup and a blank, black screen results. I hear laptop running. I forced closed it and re-started again. Same...black screen as I hear laptop running.
Also, is there a certain order for rams to be installed? Originally, the 1GB ram was first, and the 2GB was below. I installed the 4GB ram below and moved the 2GB to top first position. (in case I want to access the 2GB easily to upgrade with another 4GB)

I have the following problem with my computer, lenovo sl 510: when pressing the power button, the computer won´t boot. On the display you can see a black background, in the upper right corner the intel emblem and in the lower left corner you can see "thinkpad". I cannot enter the bios and nothing works. We´ve tried already to press the power button a few times to reset the computer. Didn´t work as well. The keyboard doesn´t accept any hot key combinations.

I want to upgrade my SL510 (28577MG) with a new Crucial M550 512GB SSD. The Crucial website says that the drive is compatible with my laptop: [URL] ....
Unfortunately neither the Windows 8 Install CD nor my BIOS can detect the drive. Here is a list of steps I tried to solve the problem:
Change the SATA Controller Mode Option in the BIOS from AHCI to Compatibility
SSD does not get detected in BIOS2. Update the BIOS to the latest version 1.52 (6JET94WW)
SSD does not get detected in BIOS3. Run the 2.5 inch SATA Hard Drive Firmware Update Utility
[URL] ....Utility can't detect the SSD / find any updates4. Look for a firmware update on the Crucial homepage
[URL] .... There are "No firmware updates"...
I also installed the SSD in my desktop (Gigabyte GA-MA770-UD3, 770) where it is detected in the BIOS and in Windows 7. So it is definitely in working condition.

Just got a Thinkpad SL510 2847 D2U, Windows 7 Prof.(64 bit).
Often when I touch the Touchpad I see the arrow on screen change to a "button" being displayed. And the button is not like using the arrow. Very difficult to work with it. So I keep moving around Touchpad to get rid of the "button" and return to arrow.
How to rid of this "button" action? Or what am I doing to cause it? I believe I have changed the sensitivity of the touchpad. I'll check again.

I have the following problem - after upgrading to Windows 7 I have only volume controls working, but not Fn+Fx key combinations.
Details are:
1) Fn key physically works - it worked on Vista
2) In order to have volume controls working I had to install Visual Studio 2010 Redistributable package
3) My BIOS version is 2.24, tried downgrading to 2.23 as well
4) System Interface Driver is installed alongwith Hotkey Support
5) Power Manager is installed
6) Tried older Vista drivers

Another problem on my Lenovo Thinkpad L520: After installing the Lenovo Power Management Driver, I can no longer adjust the LCD brightness by using the FN+DEL/POS1 keys. Immediately after adjusting the brightness, it gets reverted to its old value, set in the Power Management software.
I tried the Windows 7 driver (1.65.05.21) and the WIndows XP/7/8 driver (1.66.0.22), both with the same result.
This is really annoying and I am very frustrated with Lenovo right now, since this is not the only problem I am having with the laptop.

I've had several laptops but I am hating this one and is basically the Fn Keys and F# Key. I am pretty customed to use keys like F4(invoking word magic), F5 (update), Alt+F4 (closing windows)...
So, now I have to press Fn + F4 Keys, Fn + F5 Keys and Fn + Alt + F5 Keys....
So is there a way to continue pressing just F4 F5 and that's it?

Just a got a brand new Thinkpad 540-E. So far this CPU runs like a beast(with a new SSD installed). I have one minor issue though...
GOAL:: Make the F1-F12 keys function without having to press Fn first.
So I've tried the three tips I've come across online. Here is what happens:
1. BIOS(ThinkpadSetup): I only get the option to switch the Fn and Ctrl key. There are no option in my BIOS to do anything else with the keyboard/mouse settings.
2. Holding down the Fn key for 30 sec to 1 minute: Nothing happens. I even tried to do a three minute press and hold. I had a blast, but nothing came out of that neither.
3. Entering the keyboard settings in Win 7 manually: So I have no trouble entering the keyboard settings window, but mine looks extremely limited. In fact I see no options to do anything in there besides updating the driver.

I have the Lenovo L440 (20AT002YGE) with the integrated Intel Graphics.
I have turned off the automatic dimming of the screen brightnes in the windows energy settings and also turned off the energy saver settings in the Intel driver but the screen keeps beeing dimmed when the background is black or dark. This is very annoying when you work outdoor and the sun keeps shining on your display and than it dimms the brightness.

I have a thinkpad l520 5016-c74 running windows 7 64bit and kubuntu 13.04.
When i try to adlust the brightness in kubuntu, the jotkeys work just fine.
On the other hand, in windows, i can adjust the brightness from the windows menu, but every time i hit Fn+home or delete (this is the hotkey on my machine) the brightness, regardless of where it is set, drops to 7 (from a scale of 1-15), and cannot be readjusted, If i hit again Fn+Home or Delete, it does this flash, like it's trying to change the brightness, but something holds it in 7. I can always change it from the windows menu. But again the same thing, hotkey and back to 7.

I have a W500, ATI Mobility FireGL V5700, Windows 7.
When I press FN+Home and FN+END to regulate brightness up or down, the brightness symbols turn on and goes up/down, but the screen brightness is not regulated up or down but stays constant somewhere in between.
What can I do to get "brighness" working?
It has never worked, the computer is 2 months old. I have upgraded from Windows 7, 32 bit to 64, but brightness is still not working.

S440. I prefer to use the function keys F1-F12 without using the Fn key. It seems like in other models there is an option in the BIOS to change this, but not on my machine. Also the Lenovo software nor Windows configuration seems to be able to change this. Is there anyway to do this?

I just purchased these 2 new dual monitors whose input connectors only come in HDMI, DisplayPort, and Mini DisplayPort. I'm using a X230 with a Ultrabase 3 and I can't seem to get the 2nd monitor up and working... My first one is being used through the displayport direclty on my laptop (left side).
Is it not possible to get both monitors using a combination of these cables? Would buying a converter (HDMI or displayport --> VGA) solve the problem?

I have a brand new W540 with Windows 8.1 running. Some Fn-Keys are working, for example Fn+F2 for the volume. But I have some keys which are not working: Fn+F5 or Fn+F6 should change the LCD brightness.
Why these keys are not working? All updates are applied (Lenovo and Windows)...

Knocked half a glass of water over keyboard yesterday. Turned off & wiped away straightaway. No problem re-booting etc but now some kets along top 2 rows not working.After a day - do you think there's any chance these will spring back into life?Do Lenovo supply any on-site repair options (at a cost obviously).....can't spare time at moment to send away - even for a couple of days.
