Lenovo X Series ThinkPad :: X120e Funtion Keys For Brightness Not Working?

Mar 29, 2011

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.

Lenovo ThinkPad W Series :: W540 - Display Brightness Keys Not Working / Audio Channel Commutation Gets Stuck

May 27, 2014

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?

Lenovo X Series ThinkPad :: X120e Running Very Hot

Oct 19, 2012

My x120e has been getting hot ever since I've got it.

Not doing much of anything, it'll be 75-80 degrees C. Full load, 95-99 C.
 
I've tried replacing the thermal compound, replacing the heatsink, the cpu is undervolted. It still runs quite hot. As I write this, the computer is 97% idle and still at 77 degrees C. It's sitting on a hardwood floor, so the vents on the bottom that I just blew out are clear.

Lenovo X Series ThinkPad :: X120e - Simplest Way To Reinstall OS?

May 17, 2014

I have an x120e that's a few years old, works fine but is slow as mollasses.  I want to do a fresh install of the OS, and want to do it in a way that brings the fewest headaches.  I see there is a recovery partition but what that is for.  I have googled this and seen suggestions but those ways seem to eliminate the built-in Lenovo functionality like the f keys and such. 
 
Any easiest way to reinstall to speed up the machine without having to track down drivers and Lenovo-specific add-ons?
 
Love this machine, by the way.

Lenovo X Series ThinkPad :: X120e Bluetooth Non-existent?

Mar 19, 2011

I ordered my laptop from cdw (will post link when cdw gets finished with their downtime).
  
On the one I ordered, it said that bluetooth was included. As a general rule I always re-install windows after I get it, and did the same this time because I had a spare copy of windows 7 ultimate. I re-installed all the levono tools and drivers as normal, but when I got to the bluetooth one it said that my laptop did not have bluetooth. So I opened up the computer just enough to verify that the bluetooth daughter card IS there. So whats going on?

Lenovo ThinkPad W Series :: W500 Brightness Not Working

Jul 4, 2010

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.

Lenovo X Series ThinkPad :: X120e - Full Disk Encryption Of SSD

Mar 11, 2012

I'm contemplating upgrading from my Samsung 830 128gb to a Samsung 840 EVO 250gb, on my trusted x120e. The EVO has Full Disk Encryption (FDE) and I am curious to know if:
 
1. Turning on the FDE is done through the BIOS?
2. Do I need to enter the FDE password each time I reboot (like I have to with the hardware passwds?)
3. Is there a performance penalty (finite but negligible perhaps) for turning on the FDE?
4. Is the FDE significantly greater protection (in a practical sense) than just the (non-encrypting) hardware passwd (which nonetheless is quite effective in that the disk isn't recognized at all if used in another pc)?
5. My X120e is an AMD machine and the Samsung Magician software (most recent versions) works only for Intel machines. If the FDE is controlled through that sw, then I have a problem.

Lenovo X120e X Series ThinkPad :: Bluescreen On Windows Startup?

May 15, 2014

Recently, my x120e began blue-screening (with error code c000021a)  while Windows was starting up. However, if the computer was off for a period of time, usually about 5-10 minutes minimum, it would start up with no problems. I thought it might be overheating except for two things:

1) Once windows started up, I had no issues. No matter how much processing power I was using, it didn't bluescreen or even try to turn itself off

2) When I rebooted in safe mode and looked at what modules it was loading, it always failed after the same one (CLASSPNP.SYS)
 
I had heard that there were occasionally some significant driver issues with my hardware, so I did a clean re-install of Windows (Win 7 Pro, 64-bit), hoping that this would rule that out.

The issue persisted, and in fact would interfere with a Windows install disk booting into the installer. After I got the installation to complete, the previous issue continued to be present.
 
I did some Google searching and found that the BSOD error code c000021a is generally caused by a driver or security issue, and the usual solutions suggested are to try to use the "Last Known Good Configuration Option" for windows startup, and to update drivers. However, neither of these things have worked, as it still does this on a fresh Windows install.
 
I also tried running without the battery (AC power only) and without the AC power (battery only), and neither has fixed the issue.
 
(Side note: This was originally happening with the original 320GB hard disk that came in the machine. I was going to upgrade to an SSD anyway, and this problem has persisted with the new drive).

Lenovo X Series ThinkPad :: X120e - Horizontal Screen Flicker

Feb 6, 2014

My x120e has been giving me grief recently. It started when, upon awaking the computer, my screen would be very distorted. It was mostly horizontal and was different from the known horizontal screen flicker issue. It would take up large parts of the screen, but no more than half. Now get this, the distortion changed totally depending on what was on the screen. I could even get it to go away completely if I just opened the start menu (with my task bar on the left side of the screen). Typically a restart would alleviate the issue. 
 
I would get a screencap for you guys, but last night I shut down the laptop to 'fix' the issue and the screen never came back on. I can still use an external monitor so I'm not thinking this is a graphics card problem, or at least not entirely.

Lenovo X Series ThinkPad :: X131e / Win 8.1 - Brightness Slider No Longer Working

May 19, 2013

Why neither the display brightness slider nor the F8/F8 brightness function keys cause any change to the display brightness? It used to work but for the past few weeks it's not. I thought that slider was able to override any preset power settings.

Lenovo X120e Series ThinkPad :: Bad Dimm Slot / System Will Not Exit Standby

Jan 24, 2011

I have an X120e running Windows 8.1 Pro x64.I just upgraded the unit to 4GB of ram (2x2) from 2GB (1x2). Whenever the upper DIMM slot is used, the system will not leave standby mode, and all power, including the battery has to be removed from the system for it to operate normally again.
 
Of interest, all of the ram tested good with Memtest86+ if it matters the system has the e350 CPU, and a 320GB HDD.

Lenovo ThinkPad L R/SL :: L520 Brightness Controls Not Working?

Aug 26, 2013

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.

Lenovo ThinkPad Yoga S Series :: S440 Function Keys F1-F12 Without Fn Key

Jan 3, 2014

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?

Is there a way to swap the default behavior of the multimedia keys with the F1-F12 legacy keys?

Lenovo P/Y/Z Series :: Y510p With Windows 8.1 Brightness Slider Not Working

Feb 14, 2014

I will keep this short, I have a Lenovo ideapad y510p with Windows 8.1 (I got it with 8.1, did not upgrade from 8) . I noticed a problem yesterday, where I cannot adjust the screen brightness. If I use the keyboard commands (Fn + Up and Fn + Down) The slider appears on the top left of the screen, as always, but does not “slide” It stays static.
 
If I move the slider on the Setting menu, I can slide the value but the brightness does not change and the value is not reflected on the slider on the top left of the screen.
 
I am not sure when this happened for the first time.
