Hi Tomriddle,
Welcome to Lenovo Community!
As per the query we understood that you are facing issues with white screen in your Lenovo U430 laptop.
Try to connect an external monitor and check for the issue, also try to move the laptop lid back n forth.
Also try to update the graphic driver and check for the issue.
Click here for the driver for windows 7.
Click here for the driver for windows 8.
Click here for the driver for windows 8.1.
Hope this helps. Do post back if the issue persists!
Best regards,
Ashwin. S
Thank you for you fast response..
Here's what i did..
1.. powered on / off the device multiple times without any luck
2.. plugged my externeal monitor to the hdmi port... external monitor worked perfectly so i followed your advice...
however the drivers i had installed were newer than the ones provided by the lenovo download site.. but i still
"downgraded" the drivers to the ones you provided in your link.. rebooted. no luck .. updated them to the newes
ones found on windows update... rebooted.. no luck .. at this point i was about to give up..
3.. opened up the laptop and unplugged/ plugged the screen connector and turning on the laptop.. no luck..
4.. unplugged / plugged the bios battery on the mother board.. no luck
5.. unplugged / plugged the laptop battery connector and the bios battery ... no luck
6.. unplugged the hard drive and booting up the laptop without it... no luck so i plugged it back in
7.. remove the memory stick and booting up the laptop without it .. screen wouldnt even light up (power button shows it was on.. and the keyboard light went on and off like it does when it boots up.. -- something for a change!!
8.. reinstalled the memory stick and booting up the laptop.. still the same thing.. white screen followed by red.. green.. blue.. no luck
9.. i didnt have a direct replacement of the PC3L memory stick but i did have a DDR3 PC3 memory stick in another laptop.. some google search and found that as long as theyre both DDR3 PC3 they should be compatible .. so .. i replaced the memory stick.. booted up the laptop.. screen wouldnt even light up ..
10.. replaced the memory with the original stick.. before quiting i decided to give it another try before plugging in the hard drive... and ... IT WORKED.. however since the hard drive was unplugged it went to the no booting device and bios screen..
11... powered off the laptop... plugged in the hard drive... (started praying) .. turned it on.. and it worked...
12... powered it off.. screwed the back cover on .. powered it back on... and its working fine so far.. played some video.. rebooted a couple times without any issues..
i do not know if there whas a "current state" flag or data saved on the ram or if it was caused by the UEFI system..
but i guess after replacing the memory stick it cleared up or something that when i replaced it back i booted up from scratch refreshing the devices or i have no idea.. but it works now ..
hope this helps someone in the future.. .. again thank you for your time!!

U430 Touch Screen Hinge Issue

Hi,
I have U430 Touch Screen Hinge issue, but lenovo service agents are not responding even if I give them the reference of below forum. Can you please help me resolve this issue as the laptop is under warranty (bought on december 2014)and it was not damaged. It was used last night and then just closed and kept on the bed. When I returned and tried opening it, I had this hinge issue. Please help me get this issue resolve at once.

Hi, This is the third time I called them but they are persistent that it is not cover under warranty for U430T. I do understand that if it is an accidental damage then it will not be covered. But my point is, from my end, there was no damage on the laptop and simply closed it and tried opening it after a while caused it. Furthermore refering to the post link, it is mentioned by Amy Tuper that if it is under warranty and cause is not by damage contact support. It is also mentioned that Lenovo launched an investigation in which it was concluded that there was mount failure on this model. So, my question is, isn't there a possibility that this defect could have been the mount failure issue ? Last call, they state that it is just for U530T even when the post says it is for both U430T and U530T. People on the same post have posted that they got it repaired by Lenovo for free. I am not sure what to believe, the post posted by Lenovo or the support service ? Can you please escalate the issue as it is hampering my day to day work. Awaiting reply from your end.

WT10-A Touch screen Issues

I bought this less than a week ago and i am having issues with the touch screen. It just stops working all of a sudden for no reason and i have to restart to make it work. It will work fine for hours sometimes but sometimes i have to restart every five minutes. Can someone please help me solve this issue. ThanksKarman

I'm no scientist (although I did stay at a Holiday Inn Express)... but do you think that perhaps the touch screen issues a lot of folks are experiencing could be due to liquid evaporation? Maybe these people are leaving the iPhone in a hot car (or some other really warm place) for an extended period and not admitting it? I mean it is summertime.
Not liquid, but you could be onto something.
Heat is one of the few things that can cause a capacitive screen system go out of calibration, due to the effect on surrounding part specs. Perhaps that's what we're seeing.
I suppose someone with the problem could stick their phone in the refrigerator (not freezer!) for ten minutes and see if that cures their problem.
More likely, there are several different problems going on, and what works for one won't work for others.
My biggest suspicion is that a memory interface is on the edge (either power or timing), and thus weird glitches show up. Restorting the device only when it is fully charged might be one experiment. Give us a dozen bad devices, the source code, a lab with an ICE, and a coupla weeks... and we could figure out what's going on.

On my phone, the screen fails to register the finger gesture appropriately, for instance, a tap on the screen will be identified as scroll up. single touch on the back button will be registered as many taps, ultimately exiting the application.
OHH!this phone has made my life **bleep**!

Hi DesertFox899,
Welcome to Lenovo Community Forums!
Still Microfiber for Glass Panels/Touch Screen.
I would Suggest this Product from Antec
http://www.amazon.com/Antec-XL-Microfiber-Cleaning-Cloth/dp/B00584WZKG
Just wipe the screen gently not applying too much pressure and the smudges should come off.
Hope this helps
Cheers!

U430 Touch Screen Hinge

I got the Lenovo U430 Touch in late August and have noticed that the screen hinge wasn't very sturdy but it was still working fine. But today the hinge is broken and I can't close the screen properly without adjusting it. I didn't drop it or damage it and I looked it up and saw that other people were having similar issues and saying it was a production failure. Is there anyway I can get a replacement or do I have to send it in for repairs? I'm in college and I'll be needing it for a couple more weeks so I can't send it in for repairs yet. And is the $99 fee not covered by the warranty? I called Lenovo support and they said they can't look at my laptop until I pay the fee. I feel like the quality of Lenovo has declined recently. Any help would be appreciated.

This just happened to me this morning! For those of you that were working with it broken for a while...did the break impede your daily use in any way beyond the inconvenience of the hinge function? I'm teaching in Romania right now (ironically, I bought this model specifically so it would be easier to travel with) and won't be back home in the U.S. for over a month so I can't exactly send it to be fixed right away. Am I going to damage it further if I keep using it? Edit: I'm also out of warranty, AND I noticed a month or two ago that my screen stop auto-rotating whenever I tried to flip it (which wasn't often at all, so I still don't know why my hinges would break so suddenly). Am I going to end up paying for these repairs?

U430 Touch Screen not working on Ideapad

I just bought a new IdeaPad U430 laptop a few days ago and I love it. However, the touch screen doesnt work. I've looked through the forums and have tried a lot of things and none of it has helped so far. Using the f6 key on the laptop freezes the mouse but the touch screen doesnt seem to recognize my finger. Please help! Like I said, I love everything else about this laptop and I really dont want to return it.
Moderator Note; subject edited; system type added

hi graceella,
Welcome to the Lenovo Forums.
Ideally, the OS automatically identifies if you have unit with a Touchscreen or not. To check, look under Control Panel (large icon view) > System (see images below).
Non-Touchscreen:
- Link to picture
- Link to picture
Touchscreen:
- Link to picture
If the machine is showing No Pen and Touch Input:
1. The OS is not identifying the screen as Touch capable. To isolate, perform a System Recovery (via the OneKey Recovery button) to check if the issue is on the OS level (ensure you backup important files first).
If the machine is showing Limited Touch Support:
1. Recalibrate or Reset the touchscreen
2. Reconfigure the Touchscreen
If same problem,
3. Press the Windows key‌ +R, type devmgmt.msc and press Enter.
4. On the device manager, navigate to Human Interface Devices and uninstall anything that says HID-compliant device. When finished, reboot the system and observe.
5. After the reboot, press Windows key‌ +R, type mspaint and press Enter. On mspaint, try to touch the screen and observe if the touchscreen capability is working.

If the above steps doesn't resolve the issue, I recommend you contact Lenovo and report the problem (or the place of purchase if it's still possible to exchange the unit).
Regards

Lenovo U430 touch screen screen crack in just 6 months?

Hi! I brought my lenovo 6 months ago and my experience was very bad....
After i tink around 2 months. Whenever i open up my laptop, there is like a crack sound. I couldnt see anything visable until yesterday when the bottom of the screen just pop out.
I went to the service center and was told this is not covered in the warrenty and he was sure I had drop it before to have such a problem.
However I AM 100% SURE i have not drop my laptop before. My previous 2 computer could use for 5 and 4 years respectively but this lenovo brand computer that i tried is a disappointment.
I was told the estimated cost is around $300 if i would have to repair it and it would take 1 month to fully fix it.
I am a student. I have many upcoming projects to finish. Do you think i will have 1 month to fix this problem. And that $300 is just too much.
I am pretty sure it is the quality of the laptop since i have NEVER drop it before. Although i close and open the laptop many times due to the need to travel between school and home almost everyday, isit that what a laptop is for to be portable?
Please find out for me what can I do with this problem or are there any cheaper alternative out there since i am not that rich to just throw away my money for this.

I need to gather several customer-provided photos of hinge mount failures on the U430 Touch model.
If you could, it would really help me if several people could provide photos. (Please resize photos to make them smaller before posting.)
Thank you for your help,

I´m writing from Argentina, so we don´t have apple store here to go to replace the cellphone or repair it! I could buy the whole touch screen and replace it by my self, but I don´t know if is only a problem with the touch screen or maybe an issue with the battery or other hardware components!
Sorry for my English! thank you in advance!

Portege M750 Touch screen issues

I have a Portege M750 that has been upgraded to Windows 7. It came with Vista. The digitizer portion of the screen works fine but the touch portion does not. I did a complete fresh reinstall. I cleared the cache and the temp files and downloaded the driver.
The touch portion still does not work. Does anyone else have an idea, or helpful hints. Is there a way to figure out the original configuration through Toshiba?

N97 (White unbranded) - Touch Screen Issues

Hi,
I had purchased N97 white from Nokia Flagship store few months back. From the last month or so i am seen my mobile's touch screen at times freezes and then on its own works after some time. This problem lasts for few seconds to few minutes and really make the phone dead like i can not receive the call using the touch screen or green button.
I have visted flagship store many times and booked it also but unfortunately nokia care people have been flashing the software and saying that it works. Unfortunately it does not look to be a software problem. I now have again booked it and have asked for the replacement.
Has anybody else faced the similar problem ? Does anyone know what's the likelihood of i getting the replacement and what's the turn around time from nokia.
Thanks.
Sandeep

i doubt that they will replace your device if it has been more then 30 days since you bought it. they might fix it for you by swapping some components if indeed this is a hardware issue. here in the US because i have to send out the phone to another state to get it fixed it may take several weeks to get the phone back. it all depends on where you live and if you have a care center by you.
You know what I love about you the most, the fact that you are not me ! In love with technology and all that it can offer. Join me in discovery....
