Lenovo ThinkPad L R/SL :: L520 - Goes To Sleep Mode Randomly While Doing Work
May 28, 2011
The most critical issue on my week old L520 is that it goes into sleep mode seemingly randomly even while I'm doing work. (In fact, it went into sleep mode twice while writing this post.)
I have the newest (3.59) Power Management Installed with all settings set to keep the system awake, plus updated drivers for both Lenovo and Microsoft via the Think Vantage Toolbox update feature.
According to TP Fan Control the temperatures seem fine, except perhaps for the 6th and 8th sensor, where the temperature always hovers around 60c or a little below. [URL]...

I have updated some months ago, my laptop 7859-5SG from Windows 7 to Windows 8 -> 8.1 and after that the bluetooth radio doesn't work anymore.
I tried to find a driver on the driver download section for my laptop, but I didn't find nothing. First problem found, is the hotkey fn+F5 that not show nothing on the display after key press, and normally with this function I can see if the radio is on or off.
I checked on the BIOS section if bluetooth is enable, and this is on. What I can do to activate bluetooth radio again?

My question concerns the non-functioning sleep mode buttons on my Lenovo W540 20BG.
In my current power management settings, the W540 is suppose to enter sleep mode by pressing Fn4 or by pressing the round power button shortly. However, either one of these methods do not work.
My computer does enter sleep mode when usign the Windows start menu (Start->Shut Down -> Sleep).

sometime in sleep mode my Yoga fall into irresponsive mode without any possibility to do anything. The power button is simply not working - pushing it for more than 30 second not change anything... Yoga red light is slowly blinking, the fn key is lighting, the fan is working, processor is heating and this follows to full drain battery.
Is any possibility to reset or reboot this "thermal brick" Yoga mode? Some computers and tablet have the hard reset button to work with such a situation - have Thinkpad Yoga similar solution (i.e. button combination invoking reset)?

I have a Macbook Pro (17" Penryn model just before the unibody one) and it's been working great so far until recently...
Lately it's been randomly going into sleep mode and waking up just as randomly as if nothing happened. Someone told me its a RAM issue, but i'm sure it cant be that since that will usually shut the mac down instead of putting it on standby.

I just got my x230 yesterday and I'm having some weird issues.
(1) whenever my laptop goes to sleep mode. I can't seem to make it wake up. The power button would just slowly blink and would not respond to anything. I would have to hard reset my laptop for it to turn on. When I turn it back on, it would go the "Start windows normally" screen.
(2) whenever I close the lid, I'm guessing it tries to go to sleep mode, then if I wake it up, the system seem to reboot and would go to the "start windows normally" screen.
Both seems to all relates to sleep mode.

I have a quad core Lenovo W520 (i7-2820QM) equipped with Intel AMT. I have all RAM slots populated (original 2GB in each that came with the machine). I have updated to the latest BIOS (1.42 at the time of writing) and latest Intel Management Engine Firmware 7.1 (7.1.85.1216 at the time of writing). The machine has Crucial 256GB X100 SSD installed in the main compartment and a regular HDD in UltraBay.
The computer acts normally in sleep mode and restart sequence only when Intel AMT states that "ME is in recovery state..." during boot.
When it looks like AMT is happy problems begin. The problem is that when I'm trying to put the computer to sleep it goes all the way until the end per normal procedure and then suddenly decides to power itself off! Obviously Windows doesn't like this and displays recovery suggestions after starting the laptop again. This happens when connected to AC and also when disconnected from it. Also, when computer reboots it turns off all power (i.e. the display along with backlight, indicator LEDs turn off and fans spin down for a sec) inbetween and automatically starts up after that.
I've tested this on Windows 7 and openSUSE 13.1 (which I had lying nearby) and same behavior happens on both OSes. On Windows, all the latest drivers and updates were installed. So I don't think this is driver nor OS dependent - rather firmware/hardware related problem.
What is funny, it doesn't matter whether Intel AMT is activated in BIOS or not. What matters is whether the Management Engine is in some kind of recovery state or not. When it's not, computer starts acting crazy as stated above and behaviour is repeatable. Intel AMT itself seems to work however. Changing the power policy in Intel ME configuration doesn't work for sleep issue.
Some things I've also tried doing:
* Replace CMOS battery (measured its voltage before putting it in, of course) with a new one - no effect
* Tried two different brands of SSDs (OCZ Vertex 3 and Crucial X100) - no effect
* Tried both legacy and UEFI modes - no effect
* Scanned RAM for memory errors - no effect
Could Lenovo try to repeat this issue and possibly do something about this?

I have my lenovo x230 laptop set to sleep when I close the lid. When I close the lid the "sleep" icon on the back of the screen lights up. But the batter will not last through the night on sleep mode. Within five hours or so, the battery is completely drained and I have to plug in and boot up the system. I've never seen such poor batter performance during sleep mode on any other laptop I've ever owned.
Another thread in this forum blames the USB port that allows you to charge mobile phones/etc. during low-power states and recommends disabling the "always power on" option fo this USB port in the Bios settings. At least my laptop still will not make it through the night in sleep mode.
At this point, it seems my ownly option is to use sleep mode only when the laptop is plugged in and hibernation mode when on batter power, which is disappointing. I've never had to worry about this in the past with other laptops. Perhaps/probably related is the fact that the lenovo ThinkVantage Power Manager (v. 7.16) hangs at the splash screen when I try to open it, so I've been trying to manage the power through the windows control panel power settings.

Really odd issue. My touchpad does not respond at all after I wake the computer from sleep mode. The mouse buttons do not work and the touchpad is completely impossible to get to move. The only solution is to shut down the computer entirely and turn it back on.
Does anyone else have this issue? I've re-installed the mouse drivers and it keeps doing it. There is no way to re-create the problem; it just happens totally randomly (and usually very inconveniently).

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 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.

There isn't a print screen button on my new L520, know of any key combinations that do the job? or do you have to use the Win 7 snipping tool?

I've had my L520 for over a year now and have not previously needed to burn stuff to disk, so I do not know if my problem is new or old.
Essentially the drive recognises disks when they are inserted and accurately displays files already on the disk, but it gives available space as nil regardless of disk or existing file size. Additionally if a blank disk is inserted it will say that the disk cannot be read and to try formatting. These are standard preformatted disks I'm using.

I want to install a new ssd-drive, which is empty. I did create a DVD under rescue & recovery. But on startup with the new hdd, it only offers me a restore option, not a NEW system. R&R also only created ONE disc, imho thats not enough, dont I need some more for the whole system?
And I cant backup the whole windows system, because even though its fresh its 80 gig (some data was taken along, dunno which)...
And thats my problem in a nutshell: I cant create discs with ONLY the windows install-system, or rather I dont know how
I now tried 3 times, and R&R burns only ONE disc, and booting from that, it asks for a recovery. I want a new fresh virgin system...
I tried a couple of times, did not work. Had to swap back the old drive to work again.
System: Windows 7 professional
Lenovo L520

So, I've had this problem from some time now. When I put my switch 10 to sleep, and then re-open it, the keyboard is not working anymore, like it has problem recharging drivers. Same issue happens sometime when I use it in tablet mode and then reconnect the dock to it, I've a very hard time trying to make the keyboard and touchpad working again. The fact is that the usb port on the dock doesn't seem to have any problem at all, only the touchpad and the keyboad. I can't figure out if that's a software or an hardware problem.

I have a problem with My Lenovo y510p. I was working for some time on Windows 7 with no errors. I decided to upgrade my system to Windows 8.1. I did a clean install and installed all drivers from Lenovo website as well. I have a problem that after waking up laptop from sleep mode sometimes (not always) built-in keybord is not working. Solution is to turn compter sleep again and wake it up again or logoff from windows and login again.
Have any of you had such problem with Windows 8.1? I tried power management options changes that used to be a solution for other brands but with no success...

This has been happening for a few months. Doesn't do it every time. Now out of waranty.
Closing the lid or sleep mode via Win 7 shut down works. But later and sometimes immediately, when I lift the lid I have to power up and boot. Found on the forum that there is a Intel bios option? Haven't checked that yet. But; this is an AMD unit.

I just bougth the T440 and I have two main problems related to sleep mode, which both seems to happend randomly.The most common problem is that when I close the lid (the action suppose to activate sleep mode), the computer seems to freeze during the time it is going to sleep : The red light is still on as when the computer is in 'normal mode', but there is no display and the keyboard seems unresponsive. I have no choice but to restart the computer.
Sometimes the computer seems to enter in sleep mode correctly (the red light slowly goes on and off, which according to the manual indicates that the computer is in sleep mode), but when I open the lid, the screen remains black and I can see nothing but the mouse. I have no choice but to restart the computer.
It also happened once that the above problem (the second one) kept occuring even after multiple restart of the computer. The only way I could solve it was by using 'windows safe mode'. As the problems occur randomly, I am unable to say if they were already there when I received the computer, or if they started to happen after the few windows updates/software installation I did.

I have a T430 that is a couple of months old. I've had this problem from the very beginning. Decents specs (have a Dell laptop with same specs and it never has this issue).
Processor: Intel Core i5-3320M CPU @ 2.60 GHz
RAM: 4GB
Basically, after every time the laptop is in sleep mode for more than 30 minutes, once I open up the laptop and log in, there is a period of 3-4 minutes where it is EXTREMELY slow. The computer lags ridiculously...

I have original recovery cd of Windows XP for lenovo R61/T61 models. I currently have Lenovo R61 type 8933-A32 model.
It install fine, but after that in starts randomly freezing:
- In bios I choose compatibility mode not AHCI, due to fact that Win XP SP2 don't have necessary drivers.
- I updated BIOS
- I updated all the drivers via Lenovo system update utility. (no yellow exclamation marks in manager)
- Installed SP3
- Installed Intel matrix storage driver (no effect)
Freezes are random, i cannot duplicate them. In the evenet viewer I get no errors.
To stop freeze I have to shutdown the computer.
!!!! I am curently using Linux Mint 13 Mate -> not a single problem so far. Working fine, so problem in not hardware but software related.

I have a T440, and I've set in BIOS to swap places for fn and ctrl. This works great until the machine goes to sleep or similar. After awakening the machine the keys are back to their original setting, with fn being fn, and ctrl being ctrl.
I havent explored this in detail but just found the machine sporadically losing the setting, but never while I'm working on it. So either from sleep or from locked screen.
I always use FnLk as well and that is also lost when this happens. I have to restart to get back the setting for fn-ctrl swap, but FnLk i can just enable,
I run Windows 8.1 on my T440.

My Ideapad Z570 has been doing this for some time - the screen is black, lights are on, and won't wake up. I inevitably end up turning it off, so I lose my work.
I've delayed the sleep mode to reduce the number of instances...

I recently upgraded my Lenovo ThinkPad T400 with a Crucial M500 (240GB SATA SSD 7mm) and 8GB Kit (DDR3 PC3-8500 NON-ECC) RAM.
After a couple of days of trail and error I eventually installed (successfully, I might add) Windows 7 via USB. I leave my laptop on when I sleep, but in the morning it's shut off. When I power it on I get to the Windows did not shut down properly and I always select the "Start Windows Normally" option and additionally Google Chrome informs me that it wasn't shut down properly and restores my tabs.
Why it randomly shuts itself off... Also, when I try to run my system rating after one or two flashes of the screen my laptop turns off, so I am unable to do this as well.

I have had the W530 for several months now and it randomly powers off. This can occur when connected to the AC Adaptor, when running on battery, or when using the AC Adaptor without battery. Lenovo first replaced a fan, but that didn't solve. Now they are attempting to replace the system board.
W530, i7-3610QM, 1920x1080 FHD, 16 GB RAM, K2000 NVIDIA GPU, Muskin mSATA, 500GB 7200rpm, Bluetooth, Centrino 6300 AGN WiFi, Win8 Pro

I just got me a W540 with docking. It is connected with two Samsung 24inc screens. They are connected with two display ports kables from the docking. I also have a wireless logitech mouse and keybord. And a Jabra headset connected.I have reinstalled it with windows 8.1 And now I have a serious issue that both screens turns off randomly while I work. They go black for 15 sec. And then re-appear. It seems like the computer looses all USB connection also while this happens. I sometime get an error msg. saying that I connected a USB device that cant be recognized. But most of the time nothing happens.
All 3 of us at work who has a W540 has this issue. So it must be known by Lenovo. I have an ongoing case with the support. But dosnt look like we are getting anywhere. They gave me this to try: URL...We think it could be a driver issue with the USB or that the computer is swiching between the Intel and the Nvidia gfx card.I think I have tried about everything, but can not figgure this one out. I have all the latest drivers from Lenovo installed. Tried to use a wired mouse and keyb. no change, tried with a DVI and Displayport to the screen. No change.
Here is a link to Lenovos System report on my W540. URL...

I've read other forums on similar issues, but I can't seem to find one that matches mine exactly.
System: Y410p with
1tb hdd
24gb ssd
intel i7-4700
8gb ram
64x windows 8.1 (came installed)
Problem:
When I put the computer into sleep mode, it goes into sleep mode without issue. It has stayed in sleep mode for a maximum of 8 hours, but usually before it hits this long the system will turn on. It seems to run random processes and overclock the processor as the computer gets very hot. It will do this until the battery dies, or if plugged in, indefinitely.
While it is doing this I have opened the lid, pressed every key, including power, with no response. Once, and only once, upon pressing the space bar, it had actually come to the unlock screen as though it truly was in sleep (except it was still overheating and on). Otherwise my only option is hard shut down.
I've just gone around it for a while now by shutting down every time and not using sleep. But today I had put it in sleep, and placed it in my backpack where it nearly cooked itself to death.I have tried:
-I have checked the wake_armed, which currently display NONE
-I have checked last_wake
-I have fiddled with hybrid shutdown.

I'm not sure if any other user has experience this issue. I did a lenovo update couple weeks back and since then my wireless adapter would not work after waking up from sleep mode. It shows that the wireless adapter is connected to wireless network but the internet would not work. The only way i can make it work is by disabling the wifi adapter by putting the laptop in airplane mode and then bringing it back out from it. Disabling and enabling the wireless adapter does a quick fix and does allow me to use the internet without any issue for the time being. i have also uninstalled and reinstalled fresh drivers from lenovo website, still having the same problem.
