Lenovo T400 / T500 :: Black Screen On T420s And No Boot
Jun 7, 2013
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'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.
I want to run a Virtual PC in VirtualBox and get the message, that I need to enable VT-x. I have updated to the newest bios (1.31) but i still don't have the option to enable "Intel Virtualization Technology" under the Config --> CPU menu.
We installed a Kinston 240 GB SSD in the Ultrabay, and it is not fully recognizing the SSD - it does not show up as a device, though we know the machine knows it is there, and we could use Linux and ghost to it..
We then ghosted to it with no issues. We then put it in the main bay, but it would not boot.
We looked at it from the USB port of another computer, and the files looked fine. Are we missing a driver?
I installed Windows 8 x64 recently and installed all the drivers. I was pretty sure that all the devices were installed.I was having a hardware power management problem before installing Windows 8 that I was hoping was a software issue that reinstalling the OS would fix. Turns out it wasn't software, but had to have the main board replaced under warranty. Even after the main board replacement, I was still pretty sure I saw all the device drivers were installed under device manager.
I'm noticing an "unknown device" listed that doesn't have a driver installed. I know often these can be the TPM or other system device, but I have the TPM installed as well as the chipset software and power management driver. But there is still this unknown device.The only clue I have as to what the device could be is under details, the "hardware ids" property value is "rootsscbfs_storlib_bus3". A Google search brings up nothing for this string. "STORLIB" makes it seem like it has something to do with storage, but I have the Intel RST driver (11.7 from Intel) as well as the card reader driver installed. I can confirm the card reader is functioning fine too.
I have a t420s and so far I'm happy with it.Recently I purchased a MC7700 card from ebay with lenovo FRU. Everything looks smooth except that I found there is no way to turn on the mobile broadband switch.i believe I have a whitelist-removed bios otherwise it won't boot. The driver downloaded from lenovo website is installed fine, I can see the card working in device manager. I could read the iccid in windows network settings. Everything looks good, but I just can't turn mobile broadband on.
My laptop runs windows 8.1, I heard there is a thinkvantage connectivity tool that might work for windows 7 but not windows 8. I have quite a few files on my laptop and going back to windows 7 is the last option I would like to try.
I need to do a recovery on a T420s. I want to recover to same state as out of the box. I already backed up all the data. I am using the disc provided by Lenovo but cannot seem get the disc to start the process. I think I set the DVD as the first boot device but it goes right past it and into the normal start up process.
Is there a way to start the process besides from boot up?
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.
I bought a Roline DP to HDMI cable hoping to be able to watch HD content in my livingroom and not having to plug an extra audio cable as DP should carry sound too.
When I do the same as on the youtube video, I get the following settings in the control panels: [URL] ....
But there's no sound coming out of the TV. I've tried it on my SyncMaster PC/TV Screen and on my Samsung TV in the living room. On the TV in the living room, the windows audio manager shows the device, but it cannot be selected as show above. It stays grey.
I've got a T420s with discrete nVidia Optimus graphics (Quadro NVS4200M). Driver version is 126.96.36.199 for nVidia HD-Audio and 188.8.131.5296 for NVS 4200M. This information comes from the device manager. I installed my system from scratch and used ThinkVantage System Update 4.
Where the problem comes from? I could only imagine that the cable isn't capable of carrying audio, but that seems rather illogic, does it?
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..
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 have been running ubuntu on my T420s for about 2 years now. Needed a Windows box to work from home so I installed Windows 7 Home Premium - Service Pack 1 on it. Installation went smooth but Windows did not recognize my wireless card, preventing me from connecting to the internet to download and install the rest of my drivers. I tried to manually install the Intel Wireless Lan (bg, abg, abgn) for Windows (64-bit) Centrino Advanced-N 6205 which is what I thought was installed on my machine to no avail.
I have a Lenovo t420s with dualboot win7 and Ubuntu. I never had any problems until now and could switch on/off my wireless and bluetooth connections via the Hardware Switch (right bottom left of the notebook) or via FN + F5.
However, without any specific reason the wireless and bluetooth was switched off and the the system tells me that I have to switch on WIFI via the Wireless Radio Switch. However, although I can move it, it doesn't make any difference for the Switch.
I tried to reset the BIOS to Default and changed the network settings, and also rebooted several times. I won't work with any of the two systems.
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.
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.
my Lenovo T410 laptop won't start. I hit the power button and it looks like it's about to boot up. The thinklight blinks on as normal, the cd drive is checked, the caps lock button blinks on, then nothing. No display, and keyboard is unresponsive. Power light remains on; if I leave it a while the fan comes on. I can turn the machine off using the power button, but the problem remains next time I switch it on.
I've tried removing power and battery, pressing power button 10 times then holding power for 30 secs, before replacing power and battery, but nothing happens. I've tried using a different keyboard. I've tried plugging in an external monitor. No change.
This problem appeared after I left it on overnight. I have a hunch that it went into hibernation mode, perhaps, and that it disrupted some important function which it was unable to complete.
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.
We just bought 15 T430S model N1RLPGE/2356LPG. We install all our notebooks with a running DHCP/PXE environment. A formerly ordered notebook, same type, but an older BIOS (Version 2.02) accurately got itself an IP address during PXE boot and startet the installation. The new T430S (all delivered with BIOS version 2.55) don't even get an IP. I already tried updating the BIOS to the newest version 2.56, but this didn't solve the issue. I checked everything at least twice.
MAC address for IP reservation: correct. Swich (Cisco) portfast is enabled: correct. An older notebook with BIOS 2.02, installing smooth and sound.
When I start the BIOS version 2.56 notebook with a Knoppix DVD, I get the assigned IP address. But not during PXE setup. I also checked the available BIOS and PXE options of the notebook/ethernet card. No options that solved this issue.
I've cloned my HDD to a new SSD, but it will not boot. It goes into a Lenovo Think Bios splash screen / Black screen loop. I booted off a repair disk and performed a repair, but it is still doing the bios loop thing. This has happened with both an OCZ and a Kingston SSD.
I seem to have a failed brand new SSD. Before I RMA it.
-I've just used Samsung data migration to copy my C drive to a Samsung 840 Pro 128GB SSD as usual. -I went into device driver, and set the SSD to cache writes, so the SSD was working then. -I removed the 320GB SSD, installed the SSD and rebooted. -After the BIOS flash screen, the system halts with a funny symbol on the screen and a flashing cursor. -It responds to Ctrl Alt Del. but doesn't get as far as testing the DVD drive. -After replacing the SSD with the HDD and rebooting, all is fine again ... -The BIOS shows AHCI mode, and the SSD and contents (in a USB3 drive caddy) are visible and readable.
I can't use Samsung SSD magician because it won't see the SSD over USB (clever!), so can't work out how to upgrade firmware. This is an i5, 8GB, 320GB machine with 1600x900 screen, with XP Pro 64-bit.
What gives?? Others here have posted with working 840 Pros in a T420, so I think it's compatible. Could this be a SATA2/SATA3 thing or AHCI? I can't see any SATA2/3 control in the BIOS - does it just auto-negotiate?
I have a T400 2765-P3U model, and it won't boot up. When you turn it on, you see the Thinkvantage logo and it stays there. Trying to access the BIOS is non-responsive. I connected the hard drive to see if it was a hard drive issue, but it's not. The hard drive is response when connected via USB. I can't get past the Thinkvantage logo, no response when attempting to access the BIOS. It's still under warranty, so I'll probably send it in for repair but thought I'd give it a try fixing it before hand.
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)
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 got a nice T530 with built in 6205 Wireless LAN. As I tried to replace with N-6300 there comes the Hardware boot failure with error 1802 (incompatible PCI device). I just wonder as the N-6300 is in the compatibility list and the third antenna was also already built in. Is there any workaround to get this running?
