Lenovo T400 / T500 :: T440s Black Screen After Starting Windows 7
Dec 27, 2011
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 have a T440s and have an issue with the camera. It seems to turn on (little green light comes on) when I access the Windows 8 camera app or any other app (like skype), but I do not see anything out of the camera except for a gray screen with a camera icon that has a bar through it. It looks like the camera needs to be activated somewhere but where to look. I have checked the driver and it seems to be fine (no yellow warning icon), I even unistalled and reinstalled the latest camera driver from the support website but that does not change anything.
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
I just recently received my first lenovo laptop, the T440s. The overall built quality is excellent and performance is great. However, I realized there is a dead pixel on the screen. I am stilI within the 21 days return limit. I am wondering if I am able to get an exchange for one without such defect and not subject to the restocking fee?l
When I connect the USB 3.0 dock to my T440s, I then cannot get the second LCD monitor to be recognised by Windows via the USB3.0.
The monitor is not being recognised as it is is not seen as one of the optional displays in the 'Intel HD Graphics control panel' window.
The driver however for the second monitor is fully up to date and it works fine when I connect the LCD to the VGA port directly on my computer. Also the second monitor is being recognised partly by the windows OS as it comes up as a second screen under the 'screen resolution' window.
My set up is shown below. I am thinking that perhaps there is an issue with either the NVIDIA or Intel HD graphics chip. I read somewhere that windows uses one or the other depending on the load. I am worried that there is some problem with that mechanism. All driver are up to date.
System Unit Nvidia GT730M Graphics without docking connector Processor 4th Gen Intel Core i7-4600U Processor (4MB Cache, up to 3.30GHz) Display Panel 14.0" FHD IPS With WWAN
I installed clean install windows 8.1 (iso directly from Microsoft) and I was thinking, that Lenovo System Update will install all necessary drivers and tools for me.Even newest bios wasn't offered for install. However, on lenovo's website all drivers was available.
I was looking for the software to disable the touchpad. I saw a video that had the option but it was windows 8 and I have been unable to find the same options for 7. The thinkpad tab in the screen shot is not showing up in 7.
I am running 2 external displays through the ultradock on my t440s. The built in display looks nice and crisp. My second monitor is 1440x2560. The task bar is sharp and the title of most windows looks good. All programs looks terrible. Firefox is a blurry mess.
I keep having issues waking up from sleep with my T440s. It WILL NOT connect to wifi and the wireless adapter under windows adapter settings disappears. Only thing that fixes this is a reboot. I have removed "allow windows to turn this device off" under wireless settings.
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.
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.
I am just entering some numerial data and found out that there is no num lock key on the new designed keyboard. There is also no description about this in the manual. Do I need to set something to use?
I was wondering if it is possible to upgrade the built in 4gb on the T440s, Not a big deal if i cant, just wondering because I can actaully get 2 8gb sticks. how to access the built in stick.I only have the built in right now, adding the one 8( hopefully both) later this week.
I have a T440s lenovo laptop whose motherboard was replaced a few months ago.
Today I wanted to make a clean installation (windows 8) using the recover USB key I created before the motherboard replacement (note that I already used it and it was working before changing the board).
It goes through the different steps, deleting files and creating the partitions, but when it is done the computer is not able to boot on the hardrive. I have the following messages :
Intel (R) Boot agent Ge v1.5.43 copyring (C) 1997-2013 , Intel corporation ............. initializing and establishing link...
PXE-E61 - Media test failure, check cable PXE-M0F - Exiting intel boot agent (so looks like it is trying to boot on the pci lan)
Then it comes back to the boot menu where I have a choice between : ATA HDD0 PCI LAN
If I select the first one nothing happens, and the the PCI LAN gives the above error message.
I tried to reset the bios parameters to default but it did not work. So I am wondering if it has something to do with some change in the motherboard ID, bios version....
I also launched the lenovo quick storage device test to check the hard drive and all was ok. I had to change a bios option to UEFI (the new motherboard was set by default to Legacy, messing up all the recovery process)
New T440s doesn't seem to be entering 30-day standby mode.
I did upgrade the RAM and SSD after purchase. RAM is now 12GB and SSD was cloned directly from the factory drive. In Disk Manager, I do see a 12GB partition that I presume is the sleep partition? Computer is running Windows 8.1, all updates applied, as far as I can tell everything relevant is up to date. Power Manager is not installed (not installed from the factory). Rapid Start is enabled in the BIOS and set to 1 Minute for testing.
I did find that in the Windows power plan selected from the factory that Hybrid Sleep was not enabled (nor was Hibernate). I've enabled Hybrid Sleep.
Still, the computer never enters deep sleep mode. Nothing connected to the computer and no significant changes made to the configuration other than updating to Windows 8.1 and installing some software.
My LAN port seems to be unstable. I insert the cable and hear the clicking sound but no LED turns on. I have to push the cable further to get the indicator on. It may also disconnect if the cable moves.
Is this a faulty port? And, if so, what does it take to fix it? (i.e. what do they replace/fix?)
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.
Every time I open one of the Lenovo apps like like Support or Companion, I get the message "Enhanced functions for this application are available". I click the message, a browser opens up, I download "dependecypackage.exe", I install, setup asks for a restart and I let it, and the process repeats again and again. I keep getting this "Enhanced functions..." message. It is driving me crazy. How do I end this cycle?
I got a new T440s about 2 weeks ago and sometimes it doesn't wake up after it goes into sleep mode. It gets stuck on a black screen and the mouse cursor is visible, but moving the mouse or pressing keys on the keyboard fails to wake it up. When this happens, I have to restart the computer by holding down the power button for 10 seconds. I am running Windows 7 Professional 64 bit and hybrid sleep is off. I'm just really confused because sometimes it wakes up perfectly and sometimes it doesn't.
Realtek 2x2 11b/g/n wireless LAN M.2 adapter does not detect my home 5ghz network. Driver (version 2012.10.224.2014) is up to date. 2ghz band works fine. Could it be that 5ghz is not supported by this $2k laptop?
I just bought a new T440s at Lenovo online. But when I started my coumpter, I found that all the storage of my hard disk is under C. I want to partition them into C , D ,F and E. I don't want to get the new system mess up.
