Lenovo T400 / T500 :: T420S Compatible With Kingston 240 GB SSD?

Nov 16, 2013

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?

Lenovo T400 / T500 :: T420s Is Randomly Crashing

May 29, 2012

Lenovo T420s is randomly crashing. There is nothing special in the Event Viewer. Only that the PC was not turned off properly. Not exactly BSOD.
Error video on YouTube

Usually happening under some load (eg. game) but I have seen the same  running only MS Office. No Macros or special calculations.

I would say this happens due to overheating. This is my second T420s I have same problem with. I work as 2nd. lvl IT so I know other colleagues are experiencing the same.
Frequency decreased once performance settings in power management were switched to balanced mode. Not solved though.

Lenovo T400 / T500 :: T420s Windows 8 Unknown Device

Feb 14, 2013

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.

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.

Lenovo T400 / T500 :: No Way To Turn On Mobile Broadband Switch On T420s

Aug 2, 2014

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.

Is there a way to start the process besides from boot up?

Lenovo T400 / T500 :: T420s USB Storage Fails To Load Driver (Code 10)

Aug 21, 2014

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.

Lenovo T400 / T500 :: T420s - No Sound Output Via DisplayPort To HDMI Cable

May 26, 2011

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 for nVidia HD-Audio and 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?

Lenovo T400 / T500 :: T420s (4170-CTO) Windows Unable To Recognize Network Controller

Jul 19, 2013

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.

Lenovo T400 / T500 :: T420s Wireless Radio Button Doesn't Switch On / Broken

Dec 18, 2014

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.

Lenovo T400 / T500 :: T440s - Trying To Enable 30-day Standby

Nov 16, 2013

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.

Lenovo T400 / T500 :: T440 - Enable CSM Support With Script

Jan 27, 2015

How to automatically enable CSM Support on ThinkPad models (preferably T440s) during OS deployment? CSM Support is required in order to install Windows 7 on UEFI enabled machines and is desired within my organization in order to be prepared for a migration to newer Windows OS:s later on in the future.
I've been reading through the documentation (sb_deploy.pdf) and the supplied samples found in the link below, but I'm unable to identify the correct setting.

Lenovo T400 / T500 :: T420 - BIOS Greyed Out

Sep 28, 2014

I purchased this wonderful machine from a friend of mine after he had me install a copy of Windows 7 (64) onto it.  I am not entirely sure when this problem started.

Problem: I can access my BIOS, but my settings are completely greyed out, I cannot select, much less change anything in it. After startup and I press the "BLUE" button, it prompts me for a power up password, so I press the enter key without typing anything in, which is how I believe I set it, and it allows me to "see" the BIOS settings. I am never prompted for a SVP as I do not believe there is one, although when gazing into the mystic BIOS I see the security settings are as follows-

The entire section is greyed out, and I do realize that I am indeed missing some settings that ARE in my BIOS, such as HDD Password (NONE) and I believe something else.

I am trying to edit my display and optimus settings, as I am an avid game player, and the NVIDIA card appears to be a much better option, but I however, cannot.

Aug 21, 2013

I have a T430 (2342-CTO) with an i7-3520M processor that I purchased at the beginning of 2013, and I loaded Virtualbox along with an appliance. When I ran the appliance, it gave me an error something to the effect that virtualization is unavailable on my machine.I went into the BIOS and found the settings for dynamic frequency and hyperthreading for the CPU, but I didn't see any entry for virtualization - where to look or what to do to enable this feature?

Lenovo T400 / T500 :: Won't Boot (can't Access BIOS)

Nov 9, 2009

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.

Jun 20, 2014

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.

Lenovo T400 / T500 :: Cannot Enter BIOS Of ThinkPad T530

I am unable to enter the BIOS (or the boot device and application menu) of my T530. When I press Enter at the 'Press Enter to interrupt normal startup' prompt, nothing happens. It just ignores my input completely. F1 doesn't do anything either.
Otherwise my ThinkPad is working fine, but I would like to change some settings (especially change the boot device, to boot from USB).

Lenovo T400 / T500 :: Brand New T440s With BIOS Password

I purchased online a T440s brand new. I opened the box for the first time myself. When I enter BIOS it asks for password and I just hit enter without entering any password. I can enter the BIOS but i can not change any settings.

What can I do? Can a brand new thinkpad come with a BIOS password out the box?

I get conflicting information regarding the type of password. First image says it's power on which can be removed but bios says its supervisor.

Lenovo T400 / T500 :: T410 - Discrete GFX Missing From BIOS

Nov 22, 2013

I am new to having a thinkpad and I know that my system has a the intigrated graphics and the discrete nvidia nvs 3100m Optimus card. Here is the issue though.  I have been trying to run some programs that are more video oriented (gaming). I discovered that my system is only reading the intigrated graphics and doesn't even acknowledge that the nvidia card is there.  

I have updated to the latest drivers and checked the Bios to make sure things are there.  Sadly they are not.  I looked at the bios, followed the directions I found on the forum to set that to card to on only to find that the the only card it recognizes is the intigrated graphics.  So the question is, how do I get the bios and the computer in general to recognize the nvidia card on my T410 (2522)?

Lenovo T400 / T500 :: BIOS Update On ThinkPad T420 Takes Too Long

Apr 8, 2014

I think my attempt to update BIOS with a "BIOS update bootable CD" method has failed!
My laptop: Lenovo Thinkpad T420, i5 @ 2.5GHz, 4 GB RAM.
My old BIOS infos (taken from Setup before update attempt):
UEFI BIOS Version       83ET52WW (1.22)
UEFI BIOS Date (Year-Month-Day)         2011-03-24
Embedded Controller Version     83HT27WW (1.11)

I intended to update my BIOS to version 1.46 using "BIOS Update Bootable CD"  from this link: [URL] .....

1) I downloaded this ISO image: [URL] .... and burned it on a DVD-RW(DVD rewritable) medium.
2) I placed the DVD in my T420 and turned it off, then turned it on, select F12 (boot menu), selected DVD to boot from, and the BIOS update utility started.
3) In BIOS update utility I pressed "1" to read the instructions, then press "2" to update BIOS. I clicked "Y" to confirm and the update operation started.  First it said " Now updating... ", then afer about 2 minutes, it said "Still updating ..." and it stuck like this.
So, right now, this message stays on my screen for about 1,5 hours(!!!):

"Still updating...
It may take about a few minutes.
<<< CAUTION >>>
Do not turn off the computer during the update.
Do not remove the CD during the update."
Other details (on system setup and current behaviour): AC was continously plugged in before&during BIOS update, battery is OK,  no hard disk activity at all, keyboard is(seems) unresponsive, system's temperature is pretty high, but not dangerously high...

Lenovo T400 / T500 :: T510 4384-DS9 - Cannot Find Any OPTIMUS Options In The BIOS

Sep 3, 2014

I was originally under the impression that my laptop (Thinkpad T510 4384-DS9) had NVIDIA Optimus display technology, however, I cannot find any OPTIMUS options in the BIOS under display (or any other section for that matter).
The reason I would like to know is that I have recently purchased a docking station (model: 4338) and 3 external monitors which I would like to use simultaneously.
Forgetting the fact that I'm using Linux, and that for most people this wouldn’t be a challenge worth undertaking, I would just like to know if my system actually supports 3 external monitors and the laptop screen concurrently using the docking station.
