Lenovo T400 / T500 :: Display Works At BIOS Startup But Goes Black When Windows 7 Starts To Load
Sep 7, 2012
My T400 display works at BIOS startup but goes black was soon as Windows 7 starts to load.. Video out put works and I can see an UN Backlit image on the display. Is there some sort back light controller /driver that may be broken.
I bought a ThinkPad 540p that comes with preloaded Windows 8.1. As I want to dual boot the machine I tried to select the Legacy Boot option in the BIOS/Startup tab, but I can't do anything as the option UEFI/Legacy Book is greyed out and locked in "UEFI Only". Below it there is an option called: -CSM Support that is also greyed out and selected as [No]. (below these options there is a little note with an asterisk saying "Unselectable for Secure Boot").
How can I enable the UEFI/Legacy Boot option again in order to dual boot the computer? I want to be able to boot from USB or from the CD Drive.
I can't get into the bios anymore. I updated the bios via the BIOS Update Utility 2.56 and after that I can't see the "press enter to interupt normal startup" message anymore. And therfore can't get into the bios. Windows is still booting normally.
I have a T440p with Windows 7 Pro. Except on rare occasions, I am unable to log into Windows with my first swipe across the fingerprint reader. The green light is on when I do the first swipe and it immediately goes off and stays off for around 15 seconds, during which time another swipe does nothing. Then the green light will return and a second finger swipe will log me on.
It's made using the fingerprint reader for login impractical, because it's faster to just go to the password screen and log in that way.

Lenovo T400 to install Windows XP on it..It previously worked fine with windows 7 and 8.1.so it boots in windows XP preinstall screen, it formats hdd and like usual installation automatically restarts after that BUT its black screen, lights and sounds show that it works and goes to next screen BUT the screen is still black. Powering down and turn on again is not showing any screen picture. Opened it removed Bios battery, turned up after few on and off it starts it reset bios.
So now there is picture and it goes on the next screen of windows instalation like normal, after installing devices and stuff it automatically restarts like usual BUT it has NO screen again, black screen, lights and sounds again show that its loading windows end instalation screen but no picture on the screen. Reset BIOS again, it starts normaly and this time it shows BSoD with code 0x7B, after BSOD Black screen again..Maybe its a BIOS setting?!? tried installing with drivers for AHCI and tried installing without drivers for Compatible , what else can it be? Updated the bios to latest version, same result. To say it again - it works fine with other windows, but XP must be installed
A new T440s makes multiple times problems after start or sleep mode. Windows 7 comes up but instead of login screen a black screen appears. Just the F7 wireless control gives response. When it happens after wake a programs are runing in background but the screen is black.
I did already all updates, just not my BIOS, it is 2.11 but now 2.19 is available. I hesitate BIOS updates.
I could return the laptop since it is within the 2 week return garantie.
I just bought a Lenovo ThikpPad T540p as a replacement of my old Lenovo ThinkPad R61i.What i'm looking for, is to turn off the internal Display if Windows 7 is locked. On my old R61i, it was the Hotkey FN + F3. I was easy able to changing the function of F3 in the "Energy Manager 6" on the R61i.I did not found any similar option on the new T540p.Because i use is very often when i run the laptop during the night and i sleep in the same room. Then i usually lock Windows an turn off the display.
I am using T440. I just upgrade the operating system from windows 7 to windows 8 using recovery disk. I upgrade according to the manual paper in the box.
The issue is, the windows 8 is installed in my HDD with capacity 500GB and the SSD 16GB are not detected. My question is, it should be installed in my 500GB HDD or the SSD drive? What are the correct steps to do recovery if I 500GB HDD and SSD drive?
I want to upgrade my BIOS, but there is no update available for bios in windows 8.1.. My Bios version is 1.18, I want to update because i read somewhere that if your fan make noise make sure you have updated BIOS :A.. I want to know if I can install "BIOS update for win 8" in my lenovo t410 with windows 8.1..
Windows 8.1, 64bit, all drivers up to date, Nvidia 730m, intel 4600. Fairly new issue (couple of months), laptop wakes from sleep but display does not function, everything seems to be working normally during, just no display. Forced to hard restart.
Just avoiding using sleep mode for now. Seems to be a software issue, upgraded to 8.1 when purchased almost a year ago, worked fine until recently.
I have Lenovo T420s plugged into ThinkPad Mini Dock Plus Series 3 with USB 3.0 90W. The problem I have USB 3.0 port on the dock (blue one) works as USB 2.0. The laptop port works fine. I am checking it by plugging Seagate mobile HDD - when the HDD is plugged into the blue port on the dock station Windows (7, 64-bit) complains 'Device can perform faster', using laptop's port doesn't trigger the message.
USB 3.0 driver is installed. BIOS version is 1.37. Intel Chipset drivers are updated.
Device manager shows the connection as a chain of two 'Generic USB Hub's, if HDD is connected to the laptop's port its chain of 'Renesas Electronics USB 3.0 .......
I bought my ThinkPad T530 laptop in August of this year and about a month ago I used the Lenovo ThinkVantage updater and it updated the driver for my web cam. Ever since then it has stopped working.
Whenever I open the web conferencing menu, it only shows options for the microphone, and nothing for the camera. I have tried hitting Fn+F6 and accessing it via other software e.g. Skype, Oovoo, Picasa. And they say that my webcam cannot be detected.
When I checked for the webcam in device manager it said it was installed and working properly, and that the driver was up to date. I went to the lenovo website and downloaded the driver for the camera from there (g1ca16ww) and tried to update the driver manually hoping that that would fix the problem. Alas, it did not. I also checked the BIOS settings to make sure that the camera was enabled. It was.
So then I tried to reinstall the driver by uninstalling it, and using the driver I downloaded from the Lenovo website to reinstall. It installed properly, but now the webcam is no longer listed in the hardware manager and the dropdown for Imaging Devices, where it was located before, is no longer visible. I also rechecked the BIOS menu to make sure the camera was still listed there and it is. I do not know why it isn't working. I have also tried system restore and that didn't work either, the device still isn't listed. I don't want to have to wipe my computer.
My 5 months old SSD crashed and I replaced it with a Macrium created mirror. Everything seems to work except the computer no longer recognizes USB drives. The USB drives are good (checked on other devices), I've removed and reinstalled all USB hubs and drivers - the chip drivers and bios are up to date and the USBs are enabled in the BIOS AND I've done several virus scans (online and local) in safe mode (Malwarebytes, Spybot, ESET, Defender, AVG, Housecall). The USBs are recognized on boot but once Win7 boots the USB for storage devices no longer work.... however, the USB recognize keyboards and the mouse. Guessing a new OS install will fix it, however, I would rather not reinstall everything.
Had the laptop for 11 months no issues, I woke up to find the computer stuck on the startup screen. Tried rebooting, took out the battery, tried it pluged in, unpluged and it keeps stopping at the startup screen.
During a restart, a prompt to the effect of "Push Enter to Interrupt Startup" appears beneath the Lenovo logo. When I depress the Enter key, I get the message "Launching the startup interrupt menu" and then the device merrily continues on its path to launch Windows 8.1 Pro.
Initially, I thought this may have had something to do with a recent update to the Fingerprint Reader; however, de-installing that package had no effect. I can workaround this glitch; however, it was so nice to be able to simply specify something like a different boot device rather than having to go into the Setup menu.
Bought a refurb T400 and installed a PNY SSD in it. It POST's okay and I can access bios. I can also read/install Linux from DVD just fine.
Trouble is when I insert my win7 home premium DVD into the drive and boot it, I get POST and then I get a black screen. It seems to be reading the drive and when I interrupt with the Esc key or open the DVD drive, I get a Windows menu explaining that the installation has been interrupted.
I've looked at the bios options and can't see anything obvious that should be changed.
My Thinkpad T520, Windows 7 Pro takes over a minute to load any webpage after waking from sleep. The wifi icon shows that the network has connected to the internet after about 10 seconds from wake up. But if I attempt to use a browser to load any webpage, I must wait nearly a minute before the page will load. After that, pages load quickly.
This problem occurs in multiple browsers (FF, IE, Chrome). I am using Intel Centrino Advanced N-6205 wireless adapter. I've updated the wireless driver and BIOS. I've cleaned out my registry using CCleaner, and I've defragmented.
One bit of advice I've read that I've tried from these forums does NOT work: Uncheck from Device Manager under the Power Management tab for my wireless adapater the option to Allow the Computer to Turn Off This Device to Save Power. Unchecking that option (which would seem to keep the driver on) makes the problem worse because the wifi will not reconnect at all.
Looking at fitting an SSD which needs AHCI. So I looked on microsoft and saw registry edit which I've done. Then I changed to AHCI in BIOS and get BSOD so set it back. Also I see that there are problems with Smsung Pro, does any problems with Samsung evo ? Why mSATA is not recommended for boot disk and only for cache ?
Today I was surfing the internet on my Lenovo t500 ubuntu. After a Kernel Panic ( i'm not sure it was that some text on my screen ). I shutdown the computer and restart it but the screen stayed black. Not even Thinkpad logo at boot. The fan is working the lid are working, the keyboard too. So after trying to fix it i went on a walk while the computer was on and when I got back I heard the ubuntu noise when it start. So i try but terminal to run music and it works but the screen stay black. I tried to remove RAM, 10 times shutdown without battery or plug. Nothings worked. I cannot try without another screen yet..
I've purchased this ram from the lenovo site for my T440p laptop and they said its compatible with the original 4gb RAM which it has. but when I install it in the other free slot and turn it on it cames with a black screen and stucks in it!! When I take it out everything is ok and it turns on normally.
Running on Windows 7. I've read similar problems that others have posted, which is the monitor goes black during bootup. My machine boots fine, but every few minutes the monitor goes black / dies - no backlight.
This lasts a minute or so, then the display go back to normal. Then it goes black again. Then it goes back to normal. It's not sleeping, the HDD keeps on spinning.
I've checked the graphics driver - no update available. I reinstalled it anyway. The built in lenovo utility -thinkvantage- is of no support.
At this stage I'm wondering about the integrity of the motherboard.
I have a T420s that I bought a couple weeks earlier, it's a used one, so there's no warranty with it, I used it several days without any issue, I don't use it very frequently as I use my corporate one most of the time.
Someday when I wanted to turn it on, it stacks on a black screen and it beeps one beep then two other, nothing showing on the screen not even the thinkpad logo at startup, I thought it was a RAM related issue so I put the one from my corporate PC but without any luck, so I wanted to see if its graphic controller issue, I plug the VGA cable on the laptop and my TV and here I can see the thinkpad startup logo but after that I see a message on the screen telling :
"Real Time Clock Error - Check Date and Time settings. Press Esc to continue or F1 to enter setup" and when I press either one nothing happen at all, still stacks there.
Taskbar icon for Gigabit Network Connection shows "No Internet Access". But Internet access works fine. But, since the driver thinks there is no access, I have to disable WiFi to force the laptop to use the wired LAN. Device Manager says everyhting works fine. Driver update says I have the latest driver (220.127.116.11 dated 2014-05-02). My T430 with the same adapter works fine. What do I do? Only difference between T530 and T430 is the T530 is in a dock.
I've just out my hdd to check whether the ssd will fit there, just checked whether the slot is ok. Then I put back the original HHD very carefully. After that I opened the extra RAM slot, took it out and put it back, also VERY carefully. I didn't harm the laptop in any way.
Then I turned the computer on and it was just a black screen, nothing happening. No indicators lighted up, except for power button. I cannot enter BIOS, no response whatsoever.
