Thinkpad P71 Locked Up on Lenovo screen

Q: Thinkpad P71 Locked Up on Lenovo screen

Hi everyone. Hope someone can help me with this one. I have a Thinkpad P71 mobile workstation running on Windows 10.....just got it a couple months ago. Recently when I tried to boot it up, it goes to the Lenovo welcome screen and is locked up. Tried getting into computer settings through F1 on boot, but it wont let me do that either. Any suggestions?

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)

Was recently given a ThinkPad but it's locked on boot. Get two icons, and nothing more. Any ideas how I can unlock the computer without dismantling it?

I posted a similar question earlier and people referred me to the Yoga (much appreciated).  However, I was interested in the 2.6 lb carbon version with touch screen capabilities.  Asus has a Spin 7 model that is very good at 2.65lb, but I miss the red mouse toggle in the middle of the keyboard and Asus's track pad was designed too large....causing unintended tapping.  The Yoga, while nice, is heavier than I was looking for.  The 14 inch screen is about 3.3lb? the 12 inch at 3? I thought that some of the earlier Thinkpad Carbons had touch screen and was hoping they would make a return soon.  Thanks,

Neither my keys for adjusting brightness for my screen nor the manual adjustment from settings work. furthermore, a small lock icon is visible upon the screen icon. I have tried updating my graphics card but nothing has seemed to work? As described, the model I own is Lenovo Yoga 2 13 with Windows 8.1 - has anyone else had this problem?

Hi,i have Lenovo ThinkPad T470 (LENOVO 20HD0002MC) and recently has started a strange problem:While booting at first Lenovo logo shows up (where you can get to BIOS by Enter key) and right after screen goes black. When i power down laptop and boot again (sometime few times) intead of the black screen there is a prompt for Bios password, like it should have and booting continues to OS.Enter key for BIOS doesnt work while it slill get stuck on black screen just right before it loads the BIOS (after trying few times with power -off/on it gets to BIOS and i can boot normally)I have BIOS firmware updated to the latest version, so as well drivers for hardware.Im not aware of any change that could potentionally start this issue, maybe after updating bios to some newer version.Otherwise im using Windows 10 with latest updates, but i dont think this could cause the issue as its way before windows loading.Thanks for the help.

I haven't seen any topics that seem to quite replicate the specific problem I have, so here I am.Without warning, the screen of my Lenovo Thinkpad Yoga 11e tablet-notebook will turn black. It appears to be an "active" black rather than the screen turning wholly off. The rest of the computer is working normally during these times: audio carries on, keyboard and mouse input function, and nothing else seems to shut down or turn off. Keyboard, mouse, or touchscreen input causes the screen to return to normal briefly, but the only way to make it stop happening for sure is to restart the computer. I don't think it's connected to sleep functions, given that it happens while I'm actively using the computer.I don't know exactly why this happens, but it usually happens after long periods of use. At least once it has happened within an hour or so of being turned on for the first time that day, but I had a great deal of Chrome tabs open and that may have been similarly taxing. While this problem is not exactly disastrous, it is pretty annoying and well outside the acceptable boundaries of computer behavior, especially for a device I have had for only a few months. I would greatly appreciate help in rectifying this problem.

I have ben dealing with problems with this touch screen since I got the laptop.  It has been continuously ghosting, while it got better after the June update, it still ghosts without touches, until you start using the touch screen.  When using the touch screen it starts drawing gray lines in between the point im touching and the point its ghosting to (the lines arent always direct). I recently wiped my the drive, reimaged to a backup from april and tried reupdating it.  When I got to the touch screen drivers, I got through the initial setup and told it to open the update when finished but the machine froze.  Now when I try to reinstall, I get to the finish page on the update tools install, have it open the updater, but the program immediately closes.Any help would be much appreciated.

Hello, Since two weeks my Lenovo Thinkpad screen flickers on the right side and on boot up or recover from stand by. This becomes pretty annoying and I have updated all the drivers and also upgrading to Windows 10 didn't work neither. The warranty was due June this year, so I don't know that if I have to repair it that it will cost money. But I think it's strange for a screen to be broken in one year and 3 months. If you perhaps know a solution for this or know how it will be handled by Lenovo if I send it away for repairs please tell me. Yours faithfully, Joost Kolkhuis Tanke

My laptop's screen is shattered and is no  longer protected under warranty. I have been having a very hard time locating the correct replacement part for the model which is a ThinkPad Yoga 12. I was hoping someone here might be able to point me in the right direction, as replacing a screen is far cheaper than buying a new laptop. cheers!

A customer recently brought in the Lenovo Thinkpad T450s because the screen was failing.When I hook up the new screen, there is no display at all.And so I connected an external monitor through the VGA Port ( To boot the system into safemode to try to reinstall the display driver ), however the external monitor only displays a black screen and the mouse cursor and nothing more.Any thoughts on the issue? The fn+f7 combo is supposed to switch your display to external, but without being able to access the desktop due to the laptop screen display issue, it won't allow me to switch.

Lenovo Thinkpad X200, around 5 or 6 years old, used every day for past 4 years. Screen has started flickering. No black screen or white outs, just flickering very quickly/lightly, but very obvious.

Tried to check ribbon cable to screen and it seems ok. Started and restarted computer with battery in and out, checked PSU/plug with my spare set and both ok. Changed from 50hz to 60hz resolution and screen still flickers.

Have checked lenovo help site but caught no joy.

Does this sound like the screen needs replacing or the inverter needs replacing or is there something obvious I've missed ?

Apart from this screen flicker it works fine.
 

A:Solved: lenovo thinkpad x200 screen flicker

It sounds a bit as though the backlight is beginning to fail.

Does moving the screen back and forth make any difference. If so it may just be the connector to the motherboard that has worked loose and needs re-inserting.

I had been having a problem with my laptop that makes the screen reddish for almost a year. I tried everything - creating, setting, deleting Windows color profiles, updating drivers, disabling drivers... I got a bit desperate and started disabling services and processes until I disabled the following process:...and my screen was suddenly OK. Notice how the screenshot is also reddish. This again is due to that little **bleep**. I don't know what it does but it even manages to crap all over screenshots, not just the display. After I found that this caused the trouble, I deleted all of it at this location:C:\Program Files (x86)\Lenovo\ImController\PluginHost Now everything works fine and I can see white on my screen for the first time in a year.

Sometimes Windows does not recognize the screen. When I connect the Flatron 795 FT Plus screen to the laptop, the display disappears on my primary screen (the laptop screen), which is to be expected. BUT the Flatron 795 FT Plus does not display the
Windows desktop, or anything at all! To get the Windows desktop back, I have to disconnect the Flatron 795 FT Plus. I have been lucky to get the Flatron 795 FT Plus up and working, but not on the last 10+ Windows sessions.

When starting computer everything works fine, the windows logo loads, I get the welcome word on the screen and just when the screen should turn into desktop all I get i black screen with a cursor. I can access the Task Manager through CTRL+Alt+Del.
also I can turn it of manually into a sleep mode and on start up I can click on switch users and restart or shut down the computer. I tried setting it to an earlier date, but no difference. I tried the system repair - found no problems. So do not know what to do with it. It does load in safe mode.

This has happened yesterday after I have attached hdmi cable to it, which I have done many times previously without any problems, do not know if this could have any connection to the problem.

Any suggestions how to fix the problem.

I will be grateful for any help.
