Lenovo T400 / T500 :: T420 - Turn On Or Off The Wireless / Bluetooth Radio?

Jul 5, 2013

Is there a way to turn on or off the wireless/bluetooth radio when the T420 is docked and using an external keyboard? I don't want to open the lid on the T420 every time to use the Fn+F5 keys when docked.

Aug 20, 2009

I have just installed Windows 8 onto my T510i but I am unable to control the Bluetooth Radio. It seems to be constantly on.
 
If I press FN+F5 nothing happens (not even flight mode)
 
I have downloaded and installed all the drivers and software that I can from the Lenovo support website. Is there any thing I can do so that I can turn the Bluetooth radio on and off....

Lenovo T400 / T500 :: T430 - Mouse Freeze And Requires Turning Off / On Of Bluetooth Radio

Aug 28, 2013

Several times a week, my bluetooth mouse will freeze.  I can still use the touchpad or the red dot.  Fix is to Fn+F5 and stop and start the bluetooth radio.  Looking in Lenovo System Update, I can see the Bluetooth driver is a recent install and is version 6.5.1.4500 for Windows 7 [32/64].
 
Mouse is Targus bluetooth mouse, model: AMB09US

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 :: T420 - HDD And SSD / Can Use Both

Sep 3, 2013

I have a T420 Full model number: 4180-PR1
 
I have a 320 GB HDD, but it's nearly full, I am thinking about buying an SSD.

If so, where would the SSD go?

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-

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.

Lenovo T400 / T500 :: T420 Won't Boot With New Samsung 840 Pro SSD

Jan 31, 2013

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?

Lenovo T420 T400 / T500 :: What SSD Drives Are Supported

Nov 22, 2013

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.

Lenovo T400 / T500 :: T420 - Battery Characteristics Mismatch

Oct 25, 2014

I 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?

Lenovo T400 / T500 :: T420 - Maximum Supported Memory Size?

Nov 10, 2011

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?

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] .....

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...

Lenovo T400 / T500 :: T420 - USB Ports Stop Working After Undocking And Re-docking

Jul 13, 2012

I have a wireless mouse and printer plugged into the USB ports of my docking station and generally have no issues with them functioning.  However, when I take my laptop off the docking station and then return it to the docking station, the laptop no longer recognizes the keyboard and also says that the printer is not connected.  Once I restart they both work.  I have also tried to unplug the wireless receiver for my keyboard from the docking station and plug into the laptop, but it still does not work without reboot.

Lenovo T400 / T500 :: T420 - No Factory Restore Option In The Rescue And Recovery

Apr 23, 2013

I purchased my T420 one year ago and have sufficiently "hosed it up" to the point I wanted to do a factory restore. I saved all my data then proceeded to create the CDs from the Q drive factory restore. I followed the instructs for more and more CDs and once I got up to #12 I noted that the time it was taking to create them was down from several minutes to several seconds. When I got to CD number 18 I thought "this is ridicules" and I popped CD 11 back in to look at its content (via Windows Explorer). I noted it had two folders: 1) Factory restore (or something like that) which was over 500 MB in size and 2) something about data. This "data" folder contained 1 KB of data. I then looked at all subsequent CDs (12-18) and they all only contained this data file. So, rather than continuing to make these (basically empty CDs) I stopped.

I then put the first CD in and rebooted the machine. The factory restore started and I swapped CDs until I got to 12. I put 12 in and it said the required data was not present and to insert the next CD. I did this until I ran out of the CDs I had created. I had to "X" out of the restore app and now when I boot I get nothing but a dimly lit screen and a flickering hard drive light! Am I totally hosed here? How many CDs would it have required had I kept making them? I am ( obviously) a novice.

Lenovo T400 / T500 :: T410 And T420 Keyboard And Touchpad Not Working Windows 7

Jan 6, 2014

I received a T410 and worked two days on it. From one office I moved to another location and worked for some hours. After lunch I started the machine again, but neither touchpad nor keyboard is working. If I connect a pointer via USB on the machine the pointer is working, keyboard unfortunately not.
 
Ok. Admins installed it new. I worked one day, next morning same issue. Well, back to admins, reinstallation completed. Again for two days I could work without any problem. So as it happened the third time admins decided to provide me a new hardware: I received a T420. I have been working with this one week without any error.

I took the notebook home. I had been working with it for one hour. I used a USB-to-bluetooth wireless pointer. No problems so far.

I got back in the office this morning an guess what?!?!?! Same problem as for the T410: Windows is starting up but touchpad and kayboard is not working at all!
 
What did I? In my opinion nothing special:
1) Started up machine
2) Added pointer
3) Connected via WLAN to network at home (settings for Home-Network applying)
4) Packed the notebook into my suitcase and took the flight.
5) Back at the office connected via LAN to network, connected via VGA to monitor, added usb-keyboard, added pointer.
 
What can this be? I mean I'm able to destroy to different machines! Only common is Windows 7 and T4xx series...
