Thinkpad t400 Screen blank when fully opened but displays when open at acute angle

Q: Thinkpad t400 Screen blank when fully opened but displays when open at acute angle

When opened fully (at right angle) the screen is blank. I can initially see a very dim Thinkpad logo on boot but nothing else, no BIOS, grub or luks screens. Also during this time the bluetooth LED on the inverter is on. The thinklight still works as does external display: If I move the screen down towards the keyboard the display comes on and I can see the screen as normal and other inverter lights come on such as the battery light.WHILE DISPLAY IS DOWN IN KEYBOARD PLEASE ANY ONE SUGGENST ME WHAT SHOULD I DO?

Please see the picture below. This error happens randomly when I close my lid, and/or move my laptop fast from one place to the other. I get either the error screen below or a blank screen. Both the error screen below and blank screen require me to hold the power button down and reboot my W530.
 
Has anyone ever experienced this error? What is the cause of this issue? Does anyone know of a fix that won't void my warrantee?

When I adjust the angle of the screen on my Inspiron 5555, the screen goes black.  Sometimes I get black-and-grey horizontal pinstripes across the screen for a moment before it goes black.  (These stripes replace the video display -- nothing is visible beneath them.)  Initially, this only happened when I adjusted the screen to a certain angle.  Now it sometimes happens simply if the computer is bumped.
The computer is not going to sleep when it goes blank -- if I am streaming a video when it happens, I can still hear the audio.  If I attach the laptop to an external monitor like my TV and set the display to duplicate, the TV display continues to work even when the laptop screen goes blank.
I thought that maybe a cord or wire was getting pinched in the hinge, but if I press the power button to put the computer to sleep and press it again to wake it, the display comes back like nothing happened.
The laptop is about a year and a half old -- I bought it on Black Friday 2015
Anyone have any ideas?

Want to use computer in laptop mode (not tablet mode) with the screen rotated 360 degrees all the way open (to the tablet position, I guess) and with a monitor connected via HDMI.  With the computer/screen in that position, I want to use the regular on-board keyboard; sometimes it will work and sometimes it is disabled.  Some toggle I'm missing? I set the computer to ask before enabling tablet mode when I swing the screen around; I tell it no, but it still randomly disables my keyboard. Feels like there's a simple solution to the randomness somewhere, since I know it IS possible for the keyboard to work with the screen fully rotated. Doug D

I have a Toshiba Satellite P745. When I close the lid the fan stays on and so does the light for the power button, then when I open the lid the screen stays blank and the computer doesn't start. I have to then manually power it down and it then works fine. Some other information when the laptop first starts it asks me if i want to use windows 7 or perform a system restore, then the screen that tells you your computer didn't shut down right (the screen that gives you the option to run in safe mode) and then it starts fine. It also once in awhile makes a weird clicking noise in the bottom right corner. I have tried taking out the battery and that didn't work.
Thanks for the help

Some advanced power setting changes are possibly needed.

A "clicking noise" is usually not a good sign and may indicate the hard drive is dying.

I usually connect the vga cable from my monitor to the port on my gpu,but for some reason it doesn't display anything now.

I tried to locate the source of the problem by doing these

1) Connected the vga cable from my laptop to the monitor, and it displays the laptop's content just fine so the monitor/cable isn't the issue.

2)Connected the cable to the vga port on my samsung smart tv and to the slot on my gpu and my desktop boots and functions just fine.

3) I opened up my cpu cabinet and dusted the ram and the video card and put everything back in place but that didn't help either.

I don't have a DVI cable with me so I can't check if that works and I don't have another similar monitor either I can test it on other than my tv.

Video card: AMD HD6770

Monitor Samsung 23'S22B series
 

A:Monitor powers up, displays blank screen.

Before anyone can help you, you need to post ALL of your exact system specs; ie exact mb installed, exact cpu installed, exact pw supply installed, etc, etc, etc. If this is a big box system ie dell, hp, whatever, then post the exact make and model# If you have a service tag, post that as well.

Next is this a relatively new build or has this system been running fine for a while?

I have an Acer AspireOne D150-1322. When the netbook is open less than 45 degrees I can view and work on the computer, but if I open it greater than that the screen starts flashing Grey, White, Red, Green, Blue, and other colors like it's during a screen test.

When I lower the screen to less than 45 degrees it is ok again. If I connect an external monitor to it, the display on the external monitor is fine if I open the netbook all the way, but still flashes different colors on the netbook.

Anyone seen this before?

Thanks.
 

A:Netbook Screen Not Working When Fully Open

My initial thoughts would be a dodgy connection somewhere. How old is the machine, is it still under warranty at all?

If not, you could always take the screen casing off and check the connections to the screen / inverter board. They are normally just plug in type cables and may have become loose.

A:thinkpad T400 Ram Upgrade

RAM: You need a minimum of PC3-8500 1066MHz DDR3. However faster chips like PC3-10600 1333MHz DDR3 or PC3-12800 1600MHz DDR3 will work fine as well.
 
If there's little or no difference in price I'd buy the faster memory. The reason is that if I upgrade to a new(er) notebook it's more likely the RAM will work at full speed on that system.
 
Note also that while you can upgrade to a maximum of 8GB (2x 4GB) with a 32-bit OS like WinXP-32 you won't be able to utilize more than 3GB.
 
SSD: Any of the drives you've listed will work well.

I honestly have no clue what could have caused this!  I turned it on this morning & it was stuck on the booting screen. It read "ThinkPad" in large letters followed by "To interrupt normal start up, press the blue ThinkVantage button." I waited for about a half hour for it to boot & it never did. I of course pressed the ThinkVantage button & to my dismay...nothing happened. Afterwards, I unplugged it & removed the battery pack. I then plugged it back in & attempted to start it up again. Once again, nothing. I unplugged it again & attached the battery pack. At that point I tried starting it up again and N O T H I N G!  What do I do?!

Hi, I've searched the forums and elsewhere online, and I can't find any real help for this issue. I'm running Win 7, and I have the most up-to-date drivers from the Lenovo site. I have turned on loudness equalization, but it has not helped the problem. This is an across-the-board problem. What I mean by that is, this problem persists regardless of the application, which I happen to be using. For instance, I use Media Player Classic: Home Cinema to watch movies. If the volume is at 0%, as I begin adjusting it upward, the volume level rises. However, as I reach about 70%, the volume stops increasing. There are audio adjustments w/in the application to boost the volume, but they serve to provide minimal effects. Overall, the volume is incredibly low. If you're sitting more than a few feet away from the laptop, it is inaudible. I don't know what else to do, and I was hoping that someone might offer some assistance. Thank you.  Jeff

Did you check with different power adapter or with different power socket?
Is the CPU fan running with regular speed?
Boot the system into ?Safe mode? and check if the issue persists there also?

Here are few things I did so far without any luck: 1. Removed battery and AC adaptor waited few minutes put it back - same problem2. Removed CMOS battery. DIMM cards waited for ten minutes replaced - same problem tried with swapping  DIMM cards - when I put only one card on top slot it says put the card on zero "bottom" position. After placing the Mem card on the bottom slot no thing happens. It beeps again and sit. When I checked in the manual it says either DIMM or System board. I do not know which one is giving me the problem. I just do not want to replace all parts without knowing. Can any body help please or had similar issue and solutions if you managed to solve it.

Now, I suspect that the inverters are fine and I'm wondering about the LCD switch or LCD cable. I suppose I could just buy a cable, but before that, I wanted to take a step back and try to figure out if I'm overlooking anything. I've not been able to find a picture or location of the t400 lcd switch in either the lenovo hardware manual for the t400 or elsewhere online.Hi,I've got a thinkpad t400 with CCFL backlight. I recently replaced a bad LCD (the backlight was working at the time) with a new one. However, while the new screen works, it's backlight did not. I ordered a new inverter and plugged that in - still didn't work. I grabbed the old screen's backlight and tried it with both inverters - did not come on. I then grabbed another laptop I have and plugged in the old screen's backlight - it came on. Plugged in the new screen's backlight (while lcd was still plugged into the thinkpad), it's backlight came on.So, I know both backlights are fine, and suspected I just had a crappy inverter. I got a replacement new inverter and it still doesn't work. Tried new lcd and old backlight with all three again, no dice. Backlights still turn on when connected to spare laptop.

So I uninstalled the antimalware. So I can't really run to see if I have a virus.  To make a long story short right now NONE of the function keys work nor the THINKVANTAGE.  When I reboot and attempt to go to safe mode, bios utility I get nothing except opening up windows where sometimes the cursor will open a program or not and the trying to open programs from the start menu or the task bar is hit or miss same happens in the start menu and trying to open a browser.  I am running on Windows 7 Pro 64-bit and would like to go back to factory settings, but ag...

hey i really cant figure out what is going on. I have a wireless connection to a regular desktop, it is encrypted, and i am 99.9 percent sure the computer is clean of all malware. I can ping servers through cmd and the computer is getting assigned an ip adress, but every internet browser display absolutely NOTHING! Its really bugging me, and could use some help. Thanks!
 

A:Fully connected to wireless, yet browser displays nothing.

Hi,

I have a T400 which has the following two display adapters:

ATI Mobility Radeon HD 3400 Series
Mobile Intel(R) 45 Express Chipset Family

After installing Windows 7 and checking device manager, the ATI adapter does show up under the "Display adapters' section, but it has a ! sign on it, and if I click for details, it says:

This device cannot start. (Code 10)

I tried downoading and installing this:

Lenovo Support & downloads - ThinkPad Switchable Graphics Driver for Windows Vista 32bit and 64bit - ThinkPad T400, R400, T500, W500

and when I rebooted, it went through some diagnostic tests in a cmd window to finish installation. But when I checked the device manager again, the ATI adapter still says it cannot start.

I also tried this:

ATI Catalyst? Mobility Display Driver

which I got to by selecting W7 32-bit > Mobility Radeon > Mobility Radeon HD 3000 series.

It seemed to install OK, but I got a message which I've gotten with previous attempts, which says:

"The Catalyst Control Center is not supported by the driver version of your enambled graphics adapter. Please update your ATI graphics driver, or enable your ATI adapter using the Displays manager."

I went to the device manager, right-clicked on the ATI adapter and did Update Driver, and it did at first find a better match but said it couldn't be installed with the same error message from above (Code 10). Now, when I try to update the driver again, it says... Read more

A:W7 and ThinkPad T400 ATI Radeon 3400 series driver

I am also running a Thinkpad T400 with an ATI Radeon HD 3400 Series with Windows 7 32 bit. I cannot uninstall the current driver (8.56.1.13) nor can I update using the ATI driver package.

Any help would be greatly appreciated!

Yesterday any / all open windows on my computer (including the desktop) started to minimize and display at an angle. I can click on one of the minimized windows and bring it back up full screen but it will again minimize at an angle without warning and for no apparent reason. Any thoughts on what is causing this and how to stop it?

A:H E L P - Open windows started minimizing at an angle uncontrollably

Without knowing what you've been doing on the computer, what you've been downloading/installing/etc, I can only guess you've got some sort of virus/malware.

I was working on my thinkpad L421 last night and it showed some error and stated your laptop needs to be restarted. I did not read the notification clearly. Since then the laptop whenever restarted shows blank screen. Pressing F8 or thinkvantage also did not help.After that I googled from my phone about the problem. I removed battery, pressed start key for a minute, waited for a minute, inserted the battery and restarted. It still showed blank screen. Now in the morning, after around 12 hours, I started the laptop and it showed thinkpad logo screen. The laptop was only on batteries. I was very glad but it did not move ahead even after waiting for 5-10 mins. Pressing blue thinkvantage did not help. I connected the laptop to power source and immediately the thinkpad screen went blank. Now even after performing all measures mentioned above, I cannot even see the thinkpad screen and the screen us blank like last night. Please help.

Hi, Since I brought the laptop I have always had an issue with fixing the screen brightness. The meter would change on pressing the buttens but not screen brightness. Now, (may be after some automatic updates) my screen is completely off - I get a full black screen. I am able to access my laptop screen by connecting an external monitor and duplicating my screen. I have tried to reset the computer using recovery options but even that doesn't work. What should I do? Thank you,

I am currently running 7 64bit. I have 2 displays and when I opened up Firefox for the first time, it opened in screen1. I moved it to screen 2 and eventually it started opening in screen 2. My question is, how do I set something like that as a default. Take word for example. If I want to tell it to open in screen 2 all the time, what would I do?

TIA
 

A:Multiple Displays - Setting Defaults on which display a window is opened in

To set the Default display in 7, right click on the desktop, then screen resolution, then click on the display in the window that you want as default, and check the box for "make this my main display".

Hope this helps.

 Dear Moderator(s) I am having boot up warning with the current Bios that is recently updated in February 2017. This machine dual boots with Windows 10 and Ubuntu 16.04.2.  I am facing error and warning message from the Bios which can only be fixed by Lenovo Inc. Please review the bug and error messages below.  The bug is as follows:[ 0.000000] ACPI BIOS Warning (bug): 32/64X length mismatch in FADT/Pm1aControlBlock: 16/32 (20150930/tbfadt-623)[ 0.000000] ACPI BIOS Warning (bug): Invalid length for FADT/Pm1aControlBlock: 32, using default 16 (20150930/tbfadt-704) The ACPI error is as follows:[ 1.978280] ACPI Error: Field [TBF3] at 294912 exceeds Buffer [NULL] size 262144 (bits) (20150930/dsopcode-236)[ 1.978287] ACPI Error: Method parse/execution failed [\_SB.PCI0.VID.GETB] (Node ffff8801570b1960), AE_AML_BUFFER_LIMIT (20150930/psparse-542)[ 1.978296] ACPI Error: Method parse/execution failed [\_SB.PCI0.VID.ATRM] (Node ffff8801570b1938), AE_AML_BUFFER_LIMIT (20150930/psparse-542)[ 1.978304] failed to evaluate ATRM got AE_AML_BUFFER_LIMIT I am not certain if it affects the normal shut down. Even though i can use magic sysrq key to shutdown safely, it is a hassle to do so. Thank you for your kind assistance in issuing new update to the Bios for T400.

First, my t400 would only boot with power cord unplugged. Then it stopped booting altogether. I read to press the power button 10 times and hold it on the tenth time and to unscrew the palm rest to unplug the little battery for 30 seconds. That is the only way I can get it to boot now. I picked up a new regular battery today thinking it might be related but that hasn't solved it. Any ideas?
 

A:thinkpad t400 wont boot w/o reseting little battery behind palm rest

I looked at it closer and to get it to start i don't press the power button at all. I unplug the power cord and after unplugging the CMOS battery for awhile i just plug the power cord back in and it starts up. The first thing i see as it starts up is an error message about a bad CMOS checksum and then i have to change the date/time in the BIOS or it yells at me to do it. After all that it boots into windows 7. Once it is in windows no matter what i do to change the settings of what the power button does it still doesn't do anything. I can restart it fine but once i shut it down it the CMOS battery needs to be reset to get it going again.
