Lenovo ThinkPad Yoga S Series :: UltraBook Screen Flickers Randomly
Jul 11, 2014
I just got a thinkpad yoga and I have noticed since I started using it that the screen randomly flickers. I can't narrow it down to a time where I'm doing a specific task.
I have a w520 that is out of warranty. From time to time, the screen just turns off while I'm using it (no, not a dimming/screen off during idle isse). Everything else works perfectly though. I have to shake the laptop (lol, seriously...) and the screen comes back on! It's been getting more and more frequent. What gives? Is this a known issue? Is there some loose connection somewhere inside? What should I check?
I have an S440. I've had it for one week. Two days ago I downloaded the Windows 8.1 update from the store. Since then, when I start up the computer, it doesn't even taken me to the 'sign in' screen. There's just a black screen. When I move the cursor, it briefly appears, flickers, then disappears again.
I understand this is an issue with the graphics drivers. So I ran Windows in safemode and disabled Intel R HD Graphics family and AMD Radeon HD 8600 series graphics drivers.
This, unfortunately, hasn't fixed the problem. It still boots to a black screen with an occasionally flickering cursor. I'm currently running in safemode.
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.
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...
my Lenovo W530 Windows 7 64 bit USB's have been randomly disconnecting and connecting, the things i have plugged into them are my mouse and an external hard drive, and they just repeatedly turn off then on again? i've done some research where people have gone to their device manager then to their USB Root Hub Properties and was told to uncheck the option as show below for all the root hubs but it still does it.
i can't boot on an USB key, the secure boot is desabled and when i press enter to boot on the USB key nothing happen. I had tested with 3 different usb key and 2 different OS. And it work on other laptop i have a lenovo twist... i think its in the BIOS but i had check all options
I have disabled the secure boot and changed the boot to Legacy Only.It still doesn't work.I have also tried updating my bios to the latest version using the Lenovo Solution Center.
I've got the 12inch thinkpad yoga. The left shift key works intermittently. This started happening to me a couple of weeks ago (I've had the computer since December and haven't noticed a problem. I sent it in twice and supposedly, they replaced the whole machine this last time, but I'm still having the problem. Could this be a fault in this model in general?
It was advertised as X1 charger, but when it arrived I thought it's too small in size, so I googled it. Having done that, I've realised it's actually being sold by Lenovo as a charger for Yoga.
Am I safe to use this charger for my ThinkPad X1 Carbon (3460-CLG)?
is there any possibility to make boot from SD Card on Lenovo Thinkpad Yoga?
I have live linux image, but there are no optical drive on system, so I would be glad to use the SD Card slot. When start with boot selection, there no SD Card slot listed even if I have the bootable SD Card inserted into. On other system the same card booting properly.
Are there some bois settings to allow booting from SD Card slot, so it will be included in boot device list? The same system boot from USB, but USB consume one USB port, so the SD Card is more preferable option.
Is there a possibility of installing a 3G/LTE module on the Thinkpad Yoga? To my understanding there is an m.sata slot on the Yoga that allows for us to put extra SSD hard drives on it. Is it possible to replace it?
If not, are there other methods other than using usb-dongles or hotspots?
I have a 3444-CUU that I really love. When I first got it I realised the wireless adapter would just randomly stop working. I updated every possible driver and I'm still having the same issues. All I can do is reset the adapter to get it kicking again. I'm not sure if the wifi care is soldered or if it could be removed or replaced but I'm really leaning towards it being a hardware issue.
It'll either stop working could turkey, won't detect any wireless networks or it'll stop working and I can still view other wireless networks but I cannot connect to them. Resetting the adapter is the only option. As I'm writing this right now the wireless has gone out again. So I have to reset the adapter for 5-10 more minutes of internet just so that I can post this.
two days ago my Lenovo Twist S230u laptop started to freeze a lot, especially when I tried to multitask (like switching to a separate window). It probably took ten minutes each time for the computer to unfreeze and continue.
the in-built 'Lenovo Solutin Center' software ran an automatic diagnostic test, and said that the laptop failed the SMART short-self test (unfortunately I forgot to copy the error code). I didn't think much of it at the time since my laptop is only 5-months old. Just in case, I performed a disk cleanup, disk defrag and made sure everything is up to date. This was when the laptop began to freeze quite a lot. In desperation (and stupidity), I typed the chkdsk /r command in command prompt and asked it to run at reboot. Apparently the SMART short self test is a physical problem rather than a software problem, so obviously chkdsk won't work.
chkdsk ran for about two days now which is clearly too long for a 500gb HDD laptop. I've only used about half of this space too. I forced a shut down and now I cannot access Windows 8.1 through the boot menu (it just hangs on a black screen). Loading a rebootable USB recovery drive is not doing anything too.
I previously sought support on the Microsoft Answers website. They said that my 'hard disk is failing' and I will need to have my HDD replaced.I just want a second opinion here. Is warranty valid under this circumstance? From what I remember, 'Lenovo Solution Center' said I still had a few hundred days of warranty left on the machine.
I have a problem we need to fix because it shutdowns production. The Up and Left Navigation keys, and the Del Keys (Ent in German) do not work properly. We have press for about 5 long seconds to make them work.All stuffn Ease of Access,Keyboard is turned off and does not solve the solution.
Problem exists on IE, Word, Excel. Thinkpad Yoga S1 20C0S0AX0 T61, UZ2AQGE 2.5 Ghz, XP Pro SP3 T400s, NSF20UK, 2.4 GHz, SSD 128 GB, Vista B
Some texts look blurry on some windows. I have attached a picture to show you what I mean. If you see "Device Manager" window, the text is blurry. On the other "System" window, the text is just fine.
I have S430, bios 2.58 I decided to upgrade my HDD to SSD and install clean Windows on it.
I've downloaded Windows 7 ISO from [URL] .... Then I have loaded it into Windows 7 USB DVD Download Tool Prepared with that app bootable DVD and flash
First I tryied to install Windows from usb, installer runs and asked me for CDDVD drivers. I sat up USB3.0 to disabled, then in browser window I can see my flash, but the message about drivers remains..
Also I copyed USB3 driver from [URL] ... to another flash and tryed to give them instead of CD-DVD drivers, but they are shown as "not compatible"
Next i tryied with DVD, but I can't even load installer - DVD begin to roll, but then shows me "choose boot device" dialog. Secure boot is OFF, UEFI tryied both Legacy Only and UEFI only....
I've just bought thinkpad s540 with 1tb hdd and win8. Tomorrow i'll get m.2 128gb ssd and i'm planning to tranfer windows on it. I did nothing with OS, recovery partition is on it's place.
What should i do after replacing ssd cache with new ssd drive, step-by-step?
I have had this laptop for 7 months now, but since about 4 weeks ago when i click on shutdown i realised that it looked like it was shutting down... and 30 seconds later would fire up again. At first i thought it was me clicking the wrong button, but it has happened daily now. Only way to shut it down is my removing the power cable and then shutting down.
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?
No matter what settings are used in Lenovo settings, my display turns piss yellow after boot up. Then I have to manually change it back to normal. How do I disable that paper display?
I am trying to disable UEFI Secure Boot on my Thinkpad Yoga S1 but it keeps getting re-enabled after a reboot. If I set secure boot to disabled I can boot into the non secure OSes installed on the machine imediately afterwards but if the machine is restarted the Secure Boot seting in the BIOS is re-enabled. It's important for me to have secure boot disabled as I use OSes without secure boot.
I try to disable Secure Boot in the BIOS on the following screen :

But if I re-enter the BIOS either after booting into an OS or simply re-entering the BIOS, Secure Boot is back on:
Link to image 2
I have also tried to disable "OS Optimzed Defaults" but it also returns to enabled after a restart.
Link to image 3
Some of the other BIOS settings save correctly so I can't figure out why the secure boot settings don't. The BIOS version I have is the latest (1.18).
It's inconvenient to manually disable secure boot each time I want to use the laptop. The two operating systems (Ubuntu and Android x86) do work reasonably well once booted.
I only bought the one link pro to connect my Thinkpad Yoga 2 to my Samsung monitor with WQHD-Display with 2.560 x 1.440 Pixel. Lenovo told me that this is possible. With DVI I only get the maximum 1920 x 1200 which makes round circles look like eggs...
I need the full resolution.
I there any configuration, cable, display port instead of DVI cable?
(I have the newest, best, DVI cable (forgot the specification for high resolution DVI cable, ports)).
I just flashed BIOS on my thinkpad yoga 20CD00B1US. I got the lates BIOS 1.18/1,09 and sice this flash, I cannot make any changes in BIOS. I can list in BIOS but cannot highlite and change any setting expect quick boot Enabled/Disabled
My even manager is reporting me this warrining: : The embedded controller (EC) returned data when none was requested. The BIOS might be trying to access the EC without synchronizing with the operating system. This data will be ignored. No further action is necessary; however, you should check with your computer manufacturer for an upgraded BIOS.
I do have set up supervisor password for BIOS, password on power on. When going in BIOS, I am not asked to put password in, which could be the issue.
I just purchased a refurbished Thinkpad Yoga, and all was great for a little while. Then I decided to shut it down and set it aside for a few minutes.
Current Status: System responds in no way other than the 'i' light (in the Thinkpad logo) blinking three times when the charger is connected, or the same when the reset button is pressed while the charger is still connected. Nothing else illicits any sort of beep, light, or otherwise.
