I have a T420 Thinkpad and have 2 external monitors connected; one using VGA into the docking station and one using DVI into the docking station. The laptop does not recognize the mobile PC display as an option when I attempt to extend to a 3rd monitor. The ultimate goal is 3 monitors extended: 2 external and 1 (the laptop display). Is this possible?

I have a T420 that I'm using with a Mini Dock Series 3 - 90W 433710U docking station. I'm trying to connect to two external monitors (both HP 1965's) using the DVI and VGA outputs on the docking station. From the VGA output, I'm running a VGA (M) to DVI (M) into my monitor. I can only get either the DVI or VGA outputted monitors to work by themselves, but not together. When I connect both external displays, it will switch off one of the external monitors (the first one connected). Both are verified working as external monitors with the T420, just not at the same time. When using the DVI output, I can get dual monitors to work using the ThinkPad display as one monitor and the DVI-connected external monitor as the second. Is there a way to connect to two external monitors from a T420 with a Mini Dock Series 3 - 90W 433710U docking station? Or do you a multi-monitor adapater, such as an Cirago HDX3DV01 to do that?
View 8 Replies View RelatedIs it possible to use two external monitors with my T440p (20AW-A08500) with Intel HD Graphics withou having to buy a dock? I normally use my laptop at home with the lid shut and two monitors attached.
I used to have X1 (still do - now up for sale) and that was happily connected to two monitors via HDMI and via a MiniDP to DVI adaptor.I wrongly assume when I bought the T440p that I would be able to somehow power my existing two monitors from the single MiniDP port.I have seen their is a Lenovo DisplayPort to DualDisplayPort adaptor - but this talks about ThinkCentre usage - no mention of Thinkpads. Plus the price of this adaptor is pretty steep.
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] .....
Steps:
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...
I use a T440 with WIN8.1 pro machine but for whatever reason the external battery has stopped charging. As this laptop is only 3 months old Lenovo send me a brand new one but the outcome was the same, the charge symbol comes up on my screen when rebooting the machine and shortly after stops completely. I have now had my internal battery pack changed and again no improvement.

I have a 320 GB HDD, but it's nearly full, I am thinking about buying an SSD.
I wanted to know is it possible to have 1 SSD and keep the existing 320GB HDD and run it alongside each other?
If so, where would the SSD go?
T420 4180-PR1 - OS: Windows 7 Pro 64 bit
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-
SUPERVISOR PASSWORD [ENTER]
PASSWORD STATUS ENABLED
LOCK VEFI BIOS SETTINGS ENABLED
SET MINIMUM LENGTH DISABLED
PASSWORD AT
UNATTENDED BOOT [ENABLED]
PASSWORD AT START DISABLED
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.
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 am getting a T420 as my new Corporate laptop. I want to buy an SSD drive to replace the internal hard drive. I found the newest bios/firmware and looked at the Readme file. It lists the latest drives and model numbers but not any of the previous models? How do I get a complete list of all SSD drives/models supported on the T420? The laptop is going to be imaged with Win7 if that matters.

My T420 has the 2100 error on HDD0 few days ago. I went to the IT center and found the hard drive is completely dead. My original hdd is 500G seagate. So sad, all the music and good memories are gone.

My T420 doesn't power on at all. I have tried to turn it on with cable, w/o cable, different baterries, removed rams and tried same things, tried holding down power button for 60 secs, tried with an other keyboard and I couldn't manage to start the laptop. No reaction at all, no blinking or anything.
View 4 Replies View RelatedI have a T420 with Windows 7 SP1. I bought a replacement battery of 0A36303 (ThinkPad Battery 70++ (9 cell)) and got one with a new Replacement part number (FRU) of 45N1007 (it is clearly written on the battery alongside “ASM P/N 45N1006”).
[URL] .....
After I installed it in the laptop and made sure to run System Update and update all the Lenovo software to its latest versions.
I also run the Lenovo Battery Firmware update utility, which informed me that the battery has the latest firmware (0003-0080-0100-0165). [URL] .....
When I run “Power Manager” (latest version, 6.66.3) and choose the tab of “Battery” I have this mismatch data:
Both “Design Capacity” and “Full Charge Capacity” shows "90.00 Wh" which almost fits the characteristics of the 0A36303 battery (as detailed at [URL] .....) which is "94 Wh" (in compare with "57 Wh" for the 0A36302 model, detailed on the same web page mentioned above)
But the “FRU part number” field says “45N1001” which fits the “0A36302” model… (as detailed at [URL] ....)
Why is this mismatch?

I consider buying a new notebook and T420 is a hot candidate for me. I'm not sure yet whether I would go for a Core i5 or i7 processor, however I'm sure I'd like to upgrade the RAM in the future and 16 GB . I found out in the Intel specifications that (not only) the i5 2540 and i7 2640 that are available in the T420 configurations support up to 16 GB RAM, however in the T420 specifications concerning those processors I found that only 8 GB of RAM are supported. AFAIK the memory controller is integrated in the processor in these cases, so is there another factor that limits the size to 8 GB, or is it only an improper information in the T420 specs?
View 9 Replies View RelatedI know that the T430 equiped with nVidia graphics is capable of supporting more than 2 monitors.
What about T430 equipped with the HD4000 graphics Card, using the MiniDock Series 3?
I have connected three monitors (Dock-DVI, Dock-VGA, ThinkPad-MiniDisplayPort) but, so far, I can extend my desktop over two of these three monitors only.
I know the Intel 4000 video can only handle dual video, but is there any way have both those streams on external monitors. I have one that is extended and I would like to use another port to simply passthrough the interal display signal. I am using the series 3 miniport plus which has two digital/dvi ports and a vga out. In connecting to the second digital or the vga I get no signal. Likewise with the side VGA on the PC. I wouldn't even mind if the laptop display stayed lit as long as I could see it duplicated on a real monitor AND KEEP MY EXTENDED DESKTOP on another extenal monitor.
Seems like an obvious feature for a docking station.
I connect my T410 to an ethernet connection, open up Access Connections, and try to get the Mobile Hotspot feature working. When I click on "Start", the button just turns to "Starting..." and hangs there forever.

Is it safe to swap hardrives that are running windows 7 between two t420's? I have read in the past that the OS is tied to the hardware and doing such a swap will cause errors or blue screen.
