Lenovo T400 / T500 :: Computer Gives Only 100 Mb Wired Connection - Not 1 GB

Oct 31, 2008

I can only get a 100 Mbps wired connection (not 1 Gbps) on my T500.  I am connecting to a Net-gear GS605 switch.  I have tried using exactly the same port and cable that gives 1 Gbps on another computer (a Dell XPS 420) but the T500 will still only connect at 100 Mbps.  Both computers are running Vista Ultimate.  I have tried changing the Advanced/Link Speed & Duplex setting (in the Intel 82567LM device driver) from Auto Negotiations to  1.0 Gbps Full Duplex but this does not work.

Lenovo T400 / T500 :: ThinkPad T410 Only Boots If Power Supply Is Plugged In

Feb 28, 2011

My thinkpad T410 (2537-UQF) with an OCZ Vertex 3 SSD only boots if the power supply is plugged in. If i have full battery and try to boot without the power supply i get a blue screen after being about 60 seconds in the screen where the windows logo appears. I have Windows 7 installed fresh a few days ago.
 
I think its possible, that i have made some failure with the drivers. The ThinkPad Power Managers always stops working after booting. So i have removed the program by using the "msconfig" functionality.

Lenovo T400 / T500 :: T440p - Audio Coming From Speakers Despite Headphone Being Plugged Into Jack

Aug 17, 2012

This doesn't always happen, but I've noticed a few times on my T440p that when I have headphones plugged in, sounds comes out of the speakers. The headphones are functional and fully plugged in, yet no sound comes out of them, and the sound comes out of the speakers. I've fixed this multiple times by unplugging the headphones and plugging them back in.
 
(My problem differs from this one, where sounds comes from both the headphones and speakers)....

Apr 23, 2010

How do I turn off the UltraNav pointing device?  I just use the Trackpoint and its very frustrating to keep brushing against the UltraNav and move the cursor unexpectedly.  Note that my T400 doesn't have either the Thinkvantage Productivity Center or the Thinkpad Configuration programs installed.

Lenovo T400 / T500 :: T440 - Can't Open Top / Lid To Turn It On

Sep 24, 2008

I just got my new laptop today - but I can't open it to turn it on.  My old T61 has a little latch on one side you just flicked and it opened right up.  This has two silver things on the front, but I've tried everything and I can't get it to open.  I've pressed one, both at the same time, pressed hard, pressed lightly.  Been trying to open for over 20 minutes now but it won't budge. 
 
Will I have to send it back solely because I can't open it?

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.

Lenovo T400 / T500 :: No Display After Installing Win 7 Home Premium On T400

May 4, 2014

Bought a refurb T400 and installed a PNY SSD in it. It POST's okay and I can access bios. I can also read/install Linux from DVD just fine.
 
Trouble is when I insert my win7 home premium DVD into the drive and boot it, I get POST and then I get a black screen. It seems to be reading the drive and when I interrupt with the Esc key or open the DVD drive, I get a Windows menu explaining that the installation has been interrupted.
 
I've looked at the bios options and can't see anything obvious that should be changed.

Lenovo Yoga Flex :: 11s Won't Turn On Without Plugged In

Aug 25, 2014

I've got a Yoga 11s which is barely a few months old and hasn't seen much use. Having the same problem - it won't power on or charge (powers on only when plugged in). In Lenovo Energy Manager battery status shows "Good" and charging status shows "Battery Connected". WIndows power management icon however, shows Plugged-in, not charging. Never had that problem before either, but it came with the power-on failure so I guess they're related.

Lenovo T400 / T500 :: Kingston SSD Not Detected

Dec 28, 2012

I recently got a T440s and wanted to replace the hdd with the SSD from my old laptop, and it is not being detected at boot. It works fine in my e420s.The SSD is a Kingston V+200 240GB. It's a 7mm drive.When I turn on Diagnostic boot in the BIOS I get the following error message:

PXE-E61: Media Test Failure, check cable
PXE-M0F: Exiting Intel Boot Agent.
 
It seems like their is a problem with the connector? The SSD in the computer can actually wiggle around a little bit (<1mm), it seems like it shouldn't do that.

Lenovo T400 / T500 :: How To Handle The Ultrabay

Jul 16, 2008

A key ? for me in purchasing a new machine is how to arrange 2 accessories: DVD player and a 2nd drive (primary drive would be an SSD).
 
From what I understand, I cannot swap out a HDD and DVD in the ultrabay--if going with a second HDD, the HDD is permanently installed. This implies that you make the pre purchase decision to either have a HDD or DVD player connected by USB and the other in the ultrabay.
 
Would one opt to have the HDD in the ultrabay due to increased data throughput vs. a USB 3x port?

Lenovo T400 / T500 :: T440 F1 Key Clicking

May 30, 2014

I just opened my laptop today, and when I used F1 to unmute, it 'clicked' a sort of odd, plasticky click. I hit it again a few times, and it always clicked. So I took the key off to check. I didn't see anything wrong, no broken plastic. After taking it off and putting it back on a few times, it now only clicks when I apply pressure in the top left area of the key.

Lenovo T400 / T500 :: How To Add Camera To T530

Oct 1, 2014

I have just bought a T530 for my sister, which is due to arrive soon, but on closer viewing, I realise that it doesn't actually have a webcam. Looking at the pictures of the T530, it seems that the bezel doesn't have the necessary hole for the webcam to see out of. It looks like the space is completely filled in. Are all T530 front bezels the same? Is it possible that it is just some kind of blanking plate in the space where the webcam is behind, which can be removed?

I have been searching online but to no avail. I am not sure if I need to buy a whole new bezel for the T530 + a 720p camera (part number: 04W1364?)+ a viewing window to go in the bezel?

Here is the ebay listing of the T530 I have bought: [URL] .....

and here are the parts I am thinking of buying... do I need to buy a new T530 bezel as well? [URL] .....

Lenovo T400 / T500 :: HDD Failure Indicated On T430

Nov 26, 2012

I'm an owner of T430. I have toshiba hitachi 500gb and mini ssd 16gb running windows 7

Right now as I was working on an assignment i got a Microsoft Warning that my Hard drive was failing and that i have to run a back up (which I am doing right now)

Never had this problem and I've been using computer for awhile now and it's my first time seeing the warning window. Is there a way to see if this is a "real" problem? is it caused by viruses? and is it covered by my warranty?
 
I just ran lenovo solution center hard ware scan and passed everything except my mini ssd. with a code WHD00D001-UI4W8F.

So it seems like my hard drive is working fine, I had some problems with hardware scan failing my mini ssd before.

Lenovo T400 / T500 :: Very Dark Screen?

Oct 13, 2013

T400 -  ONE                          
 
  I have a problem with two T400 thinkpads. The first  T400 was dead when I bought it ( suspected graphics card ) . Well I managed to get this laptop to boot up. The screen was black but I found by chance that if shine a lamp or light on the screen it is working.  Now being able to see what I was dooing on the screen faintly. So I updated the bios & that did not fix the problem but I was well happy about finding out this trick. I then added 8Gb kingston ram which works with my other T400 laptops. I installed Win 7 ultimate.  The laptop is working fine. No issues  just extreamley dark screen almost black "but working"  Very strange indeed.
 
T400 - TWO    
 
 Now the second laptop was working fine. But I was swapping the parts with the non working laptop to determine the problem.  Now I have two T400 laptops with a dark almost black screen. But over about a month working on them I am making progress.  I am determind not to give up on these computers. This is not like fixing or repairing a computer. More like rezerecting a computer. I did not intend to spend so much time on these laptops but I have found a common problem that effects a lot of people. I would love to know why a  working laptop when re- assembled gives an almost black screen & still works. Normally I would just buy a new motherboard & bin the defekt one.  What I need is some command codes to try to make the screen brighter. Is this planned obsiletion or just a graphic defekt myth. Because after throwing away more supposidly dead motherboards with a graphic defekt  than I can count. I am starting to think that if I get the brightness back on my computers I will have sloved a major black screen problem. It is not the graphic processor. I have been playing fifa 14 with a lamp shining on the screen. It played fine, not jumpy ,no colour stripes just very dark.

Lenovo T400 / T500 :: T430S No IP During PXE Boot

Oct 23, 2013

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.
