Thinkpad Twist s230U no internal display, works on HDMI and mini display port

Hi,
My Thinkpad Twist does not display anything when turned on except on external monitors. The Device manager shows a greyed out internal display icon, says it is not connected.
1. Could this be the power connect ribbon cable p/n DC002C003W00 have a fractured wire(s)? I have tested for open circuit between PWR1 and PWR2 connectors and there are 4 sequential pins which are open circuit. Is this normal?
2. The touch screen works
3. There appears to be absolutely no LED backlighting working
4. Is there a possible fix for this and if so is it the power cables or some physical problem with the ribbon cables OR is it definitely a new display that is needed using existing cables?
Thanks in advance
Andrew

The last 4 pins on the connector are unused I have determined so it is not the power ribbon cable connector.
I found two wires fractured in the LCD ribbon cable right at the point where it feeds through the twist mount. I expect this could be a common problem after use. After repairing these two wires it did not fix the screen problem. I have ordered a replacement LDVS ribbon cable and will report back once I have replaced that.

Will thunder bolt display work off Ati 7970 mini display port?

Hay sorry if this has been done before, after reading a few threads i am still confused re compartiblity,
I have a MacPro 3.1 2x 3.2Ghz quad core, with an Ati 7970, it has a mini display port on it, will a 27inch thunderbolt display work of this? i understand that the thunder bolts on the back of the display will not? but also what about the usb's?

False. The reported brightness issues are very rare. The 30" is one of the best displays ever sold by Apple. Find one for $700-800.
Both the ACD and TBD have the same glare issue as the pre-2012 iMacs. They were never updated to the direct lamination of the 2012-13 iMac screens.

Display works on HDMI and VGA but not on Main Display

My G6 has been working fine for quite sometime. Just the other day the screen went blank. I can see the backlight on but there is no desktop. I use this machine quite frequently to watch movies on my Vizio Tv through the HDMI port. I tried re-booting the machine. I could hear it booting up but still no display. I decided to plug it into the TV and it displayed at that point on both TV and built in display. I can do this also with the VGA port as well. When I remove the cord from the ports I can no longer see the display. It will now only work when I have it plugged into the port.

Hi,
That means the issue is caused by some trouble within the display assembly or connectors to the board.
Have you tried doing a hard reset?
Is the machine under warranty? I would call up HP and give it for repair,
If not, you could give it to a good local computer service shop to look into it.

ThinkPad Twist s230u and ThinkPad x201 Tablet Creating Recovery Media

Hi Lenovo Customer Support,
ThinkPad s230u( model number: 3347CTO) - Window 8 Pro.
Before I start using my Laptop, I want to create a Recovery Media as is shown when installed with all partitions. Meaning if I format all contents of Laptop I want a recovery Media brings back computer as I go it in the first place include all partitions. By default there are five hidden partition and one ntfs.
What is the procedure how to Create a Recovery Media? I heard only Flash Recovery exist for Window 8.
Also I have Window 8 Pro but when I tried this link procedure http://forums.lenovo.com/t5/T400-T500-and-newer-T-series/Create-Win-8-recovery-media-in-ThinkPad-Thi... I saw only Window 8 option and even then it reboot and did not work.
Also I did Flash Recovery and Took Faster with USB 3.0 Flash around 10 min around 16GB Space
Is it possible to do CD Recovery too ?
ThinkPad x201 Tablet(Model Number: 30933PG) - Wundow 7 Pro
Can you do Flash Recovery Media and CD Recovery Media under Window 7 Pro Enviro.
If you upgrade Hard drive to 1T and RAM to 16 G RAM , Can you Still do the Recovery Media?
What is the Procedure to successfully create Recovery Media.
Thanks.

Reasons am asking this questions:
Sometime you test your computer doing a lot of things learning new technologies etc and suddenly you decide ok I want to take it back to factory state. Until now, most Thinkpad laptop does not come with recovery media. So how can I assure that my Recovery Media includes everything I used to have when I first receive unit.
I want to learn how to do that by myself by learning from the experts.
Until now what I know as follow:
ThinkPad x201:
I tried recovery media 3 DVD only with original hard drive works. I did not try Flash and not sure there is option yet.
If I upgrade unit with 1T hard drive and 16G Ram, How can I do Recovery Media?
ThinkPad Twist s230u:
I tried Flash and followed procedure on link in previous post. I took me less than 15 min to recovery whole. The question is does this process recover all the parts that is included when I receive unit.
I was unable to do recovery since I am not sure when in the Flash and during process showed to choose operating system was only Window 8 option not Window 8 Pro which came with unit.
I was able to do reset within system took longer and worked.
Is the recovery part build-in in the hardware or software partition? Is it included in the recovery Flash with all partitions?
Thank You. Awaiting for anyone to reply.

Thinkpad Twist S230u: Install clean Windows 8

Hello Together,
I got a new Lenovo Thinkpad Twist S230u and want to install windows 8 without all preinstalled Software.
But i cannot find any Recovery Disc/Partition and there is no Registration Key for Windwos 8 in the Package....
So, how can I extract the clean Windwos 8 Image to take it on an USB Stick and how do i get the Windows 8 Key?
It used to be so easy....
Thanks for your Help!

Hi bigwig,
I'm not quite sure what you want to do, but if you are looking to do a clean install without the Lenovo pre-installed software, you are headed down the wrong path.
Here's how you make a copy of the recovery image to USB flash drive. That can be used to restore your Twist to factory state. Factory state includes the pre-installed software too. There isn't a "naked" Win 8 image anywhere on the machine, as far as I know. Only the full Wind 8 + Lenovo recovery image.

ThinkPad Twist s230u cursor flashing

Hello,
I own a thinkpad twist s230u (3347 4HU) purchased 3 weeks ago. From the moment I turned it on, it has a major issue. The cursor goes on the right side of the screen, it flashes and it opens windows and applications itself whether it runs on desktop or on tablet mode. The problem appears every time I use the laptop and I can’t do anything. I can’t write text anywhere due to the cursor flashing. Also most of the times that cursor flashes, the screen jitters too! I updated the bios system to 1.57 version so as most of the rest software including Atmel touch controller firmware update tool, Synaptics ThinkPad UltraNav Driver, Auto Scroll Utility and many others. I also ran linux ubuntu from a usb flash memory but the problem still existed. So it is not a windows 8 or a driver failure. I noticed that few times when i turn around the screen or I change screen’s angle, then the problem temporarily subsides for less than a minute. I am very disappointed and frustrated. I never expected to buy a Lenovo product with such a problem.
Could anyone help me?
Solved!

I have the same issue, on a brand new Twist. So this is not some isolated occurrence. It's a serious problem. Could someone from Lenovo please respond regarding a fix or plans to address this?

HDMI to Mini Display Port not working?!?!

Hi,
I use my macbook Air (latest one with mini display port) to watch movies on my TV. I use a hdmi to mini display port adapter cable which worked perfect for about 6 months. Yesterday, I plugged my mac in and nothing appeared. I have no idea why- no settings have been changed.
As usual, the screen goes blue and then back to normal but the TV screen is plain black. In the Display settings, the 'arrangements' tab is missing where I can set mirro displays things. I tried bying a new adapter and trying this with my sister's macbook pro but it still doesnt work.
Any ideas on why this has happened & to how I can fix it?
Thanks for your help

This is probably NOT the solution you're looking for, but use a 3.5mm to 3.5mm (headphone jack) cable to transmit sound. I use stereo speakers with my setup, sounds far better than the TV.

I need to work on Adobe Premiere on my 2013 Mac Book Pro (with thunderbolt port) and display it on my 2010 iMac (with Mini DisplayPort) using Target Display Mode (TDM). I tried using a thunderbolt cable plus Option F2, but it didn't work. Will a Mini Display cable work? Any other suggestions?

HDMI to Mini Display Port problem.

When I connect my MacBook Pro 13" (early 2011) to my TV using my HDMI to Mini Display Port adapter the MacBook just shuts off completely. I can use a VGA adapter no problem but I would like to get better picture quality from HDMI. Anybody have any ideas what the problem is?
Thanks in advance.

Have you tried a different adapter/cable? This is where I would start. (see if you can borrow some).
You can also try these resets:

Can i use a hdmi to mini display port cable to use my iMac as external monitor for a windows laptop?

Does anyone know if a hdmi to mini display port cable can be used to link a windows laptop with an 27 inch iMac to use the iMac as an external monitor. Or are there other options to connect my DELL latitude 6430?

Is the 3.5mm-to-optical cable any better than using a standard 3.5mm? I don't know too much about this stuff. My thought process was that if the source of the connection is a 3.5mm jack, does it make a difference using a cable that starts as a 3.5 and converts to optical?
Chances are excellent that if your receiver is less than 20 years old it has an optical input, this is a digital signal which will sound MUCH MUCH better than using an analog 3.5MM to 3.5MM connection. I recommend using the cable suggested or one with the same connections but of a different length if your needs warrant it.

Thinkpad Twist s230u: Can no Longer Connect to the Internet

Hello,
Several days ago my Lenovo Thinkpad Twist suddenly stopped connecting to the internet. I was at the cafe using my phone hotspot and everything was fine, but then when I got back home, it could not detect any wireless networks in my house. I thought it may have just been my wi-fi but my phone could connect to the wi-fi just fine. I tried plugging in my phone again for personal hotpot and it could detect my phone, but no longer connect to the internet (it'd say that it's connected, but no pages would load). I tried rebooting my computer, but the wireless networks still could not be found and my phone's hotspot could no longer help it connect to the internet. I tried a Malwarebytes Scan but that didn't detect anything, and my McAfee virus scanner is not gonna help me find anymore viruses (long story as to why I don't have a better virus protection).
Can't really install any updates since I can't connect to the internet at all...rebooted several times to no avail...
Any sort of help or ideas would be greatly appreciated! Thank you so much!
Sincerely,
Ingrid

I just started to have similar problem. I cannot connect to interent via ethernet or wifi. Both connections show I am connected, but cannot acces any web pages. It is like it is not connected. I would like to know how to restore back to when I bought it, 12/20/13, and then re-load the Windows 8 pro that is somewhere on the partition HD. Any help out there?????? All my other devices/laptops/computers work fine on the internet.

ThinkPad Twist s230u important questions regarding performance

Hello everyone,
So, I recently bought a ThinkPad Twist (specifically the 33472GU, even though outlet said 3347XF4) from the outlet to upgrade the laptop that I take to class and I have to make a few questions that I hope get answered. I haven't really seen much attention paid to this particular device and it saddens me to see the lack of attention that it has seen.
In particular, I would have liked to see more response and helpfulness from Lenovo staff to address these concerns, but if anyone else has input, please let me know. Here is my list:
1.) It is true when they say the battery doesn't last long. I can barely squeeze 3/4 hours out of it depending on what I am doing. This is considering that I turned many of the settings down and even turned off things like bluetooth and windows 8 effects. How can Lenovo advertise 6/7 hours on this thing? No, my battery is not dead, in fact, it came with 46 mWh charge, better than what it was designed for (42 mWh). So I don't want to get sent to technical support to "fix" it. I want an honest answer and indication from staff that this issue is being taken seriously and addressed.
2.) With the above being said, is there a definitive answer from anyone about how I can extend my battery life to at least 5 hours without crippling the machine? I'm not willing to turn EVERYTHING off. That defeats the purpose of having bought the twist in the first place.
3.) Does anyone know when the Haswell version of the device is coming out? Not that I really have a choice because I already have this one. I just want to know that I didn't buy it weeks before a release so I don't feel cheated.
Otherwise, it's a great unit and concept in general. I was considering the x230t because it has everything and more (including battery life). But unfortunately it's a little overkill, much more expensive, and I couldn't find many configurations on the outlet (probably because nobody wants to return theirs).
I would appreciate any and all helpful recommendations/explanations (particularly honest ones) and I thank you for reading this.

I think our estimate of 3-4 hours of battery life is closer to real world if you are actively using the computer.
From the many forum posts, I have come to believe that the only way to exceed 5 hours is to replace the hard drive with an SSD. I have gotten such good performance after reinstalling from scratch and getting the msata working that it is hard for me to justify the $200 for extra battery life and the annoying pauses when the harddrive shock sensor is triggered.
For me, this was a "you get what you paid for" situation. I would have liked 8G of RAM and the i7 processor, but the i5 is acceptable. The only way I think you will be satisfied is if you go SSD instead of the HD. Good luck.

Thinkpad Twist S230u: Clean Install - Windows 8 on Custom Partition

I want to install Windows 8 using my own partition configuration, meaning where I'd get a C and a D drive. On my other computers, this is what I have and I really like this configuration. I want to install Windows 8 on the C drive and have all my data on D. I have reformatted and partitioned the HDD to C and D. When I slot in Windows 8 Enterprise to install, I keep getting this message "We couldn't create a new partition or locate an existing one." What the machine keeps wanting is for me to delete both partitions and create its own partitions and I don't want this. I know it wants this because I have clicked delete of the partitions and looked to see what it would do. It ended up creating several of its own partitions (not at all how I want it). When I re-partitioned the drive back to C and D (2 partition config), it would repeat that same error message.
Can someone please help tell me how do I install Windows 8 doing my own custom partition (C, D) where Win 8 is installed onto my choice of C and D is left for my data. Why does it keep saying, "We couldn't create a new partition or locate an existing one"? Is it a settings in BIOS that I need to change to enable me to use my own partition? If so, what setting? I have never had these issues installing Win 8 using the C & D partition config on 3 other computers (not Lenovo S230u Twist).
Thanks for your help!!! :-)

Hello LightspeedX!
I glad you wrote this issue cause i still having the same problem (and questions).
I decided to put everithing down on my s230u because it is quietly irritant see a last generation porcessor like the I7 on a top plataform ultrabook running so slowly like our thinkpad do.
Since the embed software and the poor resource planning is the resposable for that issue, i really cant imagine why Lenovo decide to bring all this things up together at this device. I realize that any cheap I3 china device is more confortable and "quickly" to run any software than this machine in his original state (factory defaults), so i decid to try a brand new and clean installation of windows 8 or (perhaps) a dual boot configuration using a linux frindly distro like ubuntu.
At my own risc, like the cusummer service like to say, i will erase all HD and start this "saga" (making a full hard copy first, of course and will soon bring any results i found here.

Touchscreen gesture unresponsive in Thinkpad Twist S230u

Have been using newly purchased S239u ThinkPad Twist for 4 days. The right side touchscreen gesturing to invoke charms menu no longer works (however works if use mouse in corner). Also, gesturing from the bottom does not work. Gesturing from the left side and top of screen does operate. Taking unit back to store where purchased. Anyone else have a similar problem like this?

Mine is unresponsive too. Compltely 100% unresponsive. Even after doing a complete reset and wipe of the hard drive. I already sent it in twice now and Lenovo did not fix anything. I'm ready to sue lenovo for being in breach of warranty.

Fix for slow-as-hell refurb ThinkPad Twist S230u

I recently got a refurbished ThinkPad Twist, and I was having issues with lagging - everything was taking forever, both web-based and local. Kept monitoring performance and nothing seemed amiss with memory or processing, nothing wrong with my internet connection. After a little digging I found that using Lenovo Solution Center solved my problem - it prompted me to update the BIOS, there was some kind of update related to power management, and there were some Windows patches. As soon as I did that everything was running as smooth as silk. Seems a little shady the refurb people wouldn't have done those updates since they came out before I got the laptop, but whatever, just glad I got it solved. I thought I was going to have to try a factory reset but no!
I just wanted to share here since I spent a ridiculous amount of time winding my way through the labyrinthine Lenovo website, when all I had to do was go to Start and type "update." So if, like me, you're pissed off that your brand-new-to-you machine is faulty, do yourself a favor and try that first and see where it gets you.
You can also do a hardware scan through Lenovo Solution Center - which it seems like if you just got a refurbished machine and the hardware scan didn't come out clean that would be a tip-off that they didn't do their due diligence in testing it.

Thank you. I bought my Twist brand new and it has always run slowly until now thanks to your post. I really appreciate it.
