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.

Lenovo T400 / T500 :: Prevent Users Access The BIOS On T520i And T530i?

Oct 28, 2014

In my business, we created supervisor password and enabled "lock BIOS settings" to prevent access BIOS on model T520i and T530i. But it's always possible to access on "read-only" to BIOS. How to prevent this access ?

Lenovo T530 T400 / T500 :: Boot Failure After Thinkpad BIOS Update

Mar 26, 2014

After the latest system update from Lenovo System update, my laptop T530 doesn't do a successful cold boot. A warm successive boot (with interruptible boot screen) works fine.
But cold boot always fails and the system powers down in less than 5s. This is seen after the BIOS updated to restore to older version of BIOS(downgrade it)?

Lenovo T400 / T500 :: ThinkPad T540p / Unable To Select UEFI / Legacy Boot In BIOS / Startup

Aug 7, 2014

I bought a ThinkPad 540p that comes with preloaded Windows 8.1. As I want to dual boot the machine I tried to select the Legacy Boot option in the BIOS/Startup tab, but I can't do anything as the option UEFI/Legacy Book is greyed out and locked in "UEFI Only". Below it there is an option called: -CSM Support that is also greyed out and selected as [No]. (below  these options there is a little note with an asterisk saying "Unselectable for Secure Boot").
How can I enable the UEFI/Legacy Boot option again in order to dual boot the computer? I want to be able to boot from USB or from the CD Drive.

Lenovo ThinkPad L R/SL :: R400 Freeze On Boot Before BIOS Access

Feb 10, 2013

My R400 laptop (7447-W14) suddenly freezes on boot: it displays the early logo ("thinkpad, to interrupt normal startup, press the blue Thinkvantage button"), and waits forever, neither the bios menu nor the operating system (windows and ubuntu in dual boot) appears.
I can shutdown by holding the power button more than 5s, but on reboot, the same freeze come back, whatever I do:
- holding the F1 key before and after powering on
- holding the "ThinkVantage" button
- doing this on battery, or with power supply (with or without battery)
- trying to boot on an external USB HD drive
It does not seem to be a CPU problem (nothing would be displayed), nor RAM or harddisk one (it is cheked later, at BIOS time).
In fact, I was wondering wether removing and putting back the small battery of the mainboard would solve this problem ... but this battery seems not to be eaysyly found. At least, it is not under the keyboard, where the RAM is.
of course, warranty has ended ... any way, before I throw this laptop to trash ?

Lenovo T400 / T500 :: T531 Intel 82579LM Shows No Internet Access But Internet Works Fine

Jan 22, 2015

Taskbar icon for Gigabit Network Connection shows "No Internet Access".  But Internet access works fine.  But, since the driver thinks there is no access, I have to disable WiFi to force the laptop to use the wired LAN.  Device Manager says everyhting works fine.  Driver update says I have the latest driver ( dated 2014-05-02).  My T430 with the same adapter works fine.  What do I do?  Only difference between T530 and T430 is the T530 is in a dock.

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.

Lenovo T400 / T500 :: T410 Will Not Boot With New SSD

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 T400 / T500 :: T440s Do Not Boot After Recovery

Oct 8, 2014

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 :
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)

Lenovo T400 / T500 :: T530 Boot Failure 1802

Feb 6, 2015

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?

Lenovo T400 / T500 :: SSD Slow Boot Windows 7 On T520

Jun 3, 2011

I have replaced  my old sata disk with a ssd disk . Intel 520 240 gb. on my  T520. I have a Windows 7 and a minor Linux partition. Dual boot. I have moved the old image  with Arconis True HD.
However, there is a HUGE difference in boot times between Windows  and Linux.
Windows is 1 min and 35 sec with windows logo until login screen appears. Then additional 20 seconds.

Linux is 7-10 seconds from Lenovo sign in bios until I'm ready to go. Off course I did not expect Windows to boot  as fast as Linux, but things has worsened after the change.
When Windows is up and running  the SSD disk is preforming in the same speedy way as under Linux. It is just the boot situation which is terrible. AHCI is enabled .

Lenovo T400 / T500 :: T430s - Boot From External USB DVD Drive

Lenovo T400 / T500 :: Enabling Secure Boot On T430s?

Jun 17, 2010

My laptop was running Windows 8.1 with SecureBoot enabled just fine. But I just swapped out my boot drive for a bigger SSD and, when I tried to boot from my USB installation media (to do a fresh Windows 8.1 install), nothing would happen (the screen would just flash when I tried to select the USB drive). I realized I had to disable Secure Boot in order to boot from the USB drive and then to enable booting from legacy/non-UEFI devices.
So now I've been able to install Windows 8.1 and it's running without a hitch, but Secure Boot is still in the disabled state. When I enable it, I can't boot from anything. How can I re-enable Secure Boot with my fresh Windows 8.1 install? Or if I have to reinstall, what steps do I need to take this time?

The only devices that show up are the SSD Hard Drive, the CD/DVD drive and the network boot option.
note I have tried all 3 USB ports, I have 3 different USB jump drives and each of them work when connected to other systems.

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 :: 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.

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 :: T440P - USB Boot UBCD4WIN Cannot See Hard Drive

Nov 25, 2014

IBM/Lenovo laptops and desktops for a long time. I recently purchased a T440P laptop with a standard 7200 RPM HDD in it. In the past, with previus models, when I wanted to troubleshoot the current Windows install (virus infections etc) I would use UBCD4WIN on a USB stick to boot the computer to USB and access the hard drive to pull data off or remove files infections etc. With this new T440P I cannot seem to see the hard drive when I boot it up with the USB stick.

I can boot the computer just fine and run the USB based OS without trouble but I simply cannot see the hard drive.

So far I have tried:
-Adjusting UEFI to Legacy and/or "Both"
-Adjusted CSM to Yes and No
-Disabled/Enabled Secure Boot

and several combinations of all of the above in hopes it was the issue but it doesn't seem to change my ability to see the hard drive. It simply doesn't show up.

The drive itself (in the T440P) is a standard HDD (not SSD) and is formatted NTFS with Windows 7 64bit installed on it.. The UBCD4WIN is a basic "Windows XP" x86 (32 bit) OS on a USB stick and the USB stick is formatted FAT32.
In previous lenovo models (T400/T410 etc) all I had to do was switch AHCI to Compatibility and I could see the drive but this one is giving me a real fit and I am not exactly sure if its a controller driver, UEFI or something else.
how to see the hard drive when booting to the USB UBCD4WIN stick?

Lenovo T400 / T500 :: Replacing MSATA SSD On T430 And Using For Dual Boot?

Jan 30, 2015

Replacing the stock mSATA SSD used for caching on the T430 with a large capacity SSD and placing an OS on it?
I've got a T430 with dual boot Windows 8.1 and Ubuntu.  I rarely use the Window partition, and I want leave it on the HD and migrate the Ubuntu partition over to a new mSATA SSD installed in slot currently used for caching for Windows.  I'm not concerned about Windows slowing down without the cache, but I do need a bootable windows partition.
I was about to go ahead and purchase a suitable mSATA SSD for this process when I read the hardware maintenance manual (pg 26) and mSATA update guide, which made me think that using the mSATA for anything but caching on the T430 might be problematic.

Lenovo T400 / T500 :: T440s - Disabling Internal Battery If Can't Boot

Jul 31, 2014

I just got my T440s a couple of weeks ago. I stupidly ordered it with only 4GB of RAM, thinking that I couple upgrade it myself if neccessary (and it would be much cheaper that way).
Well it seems 4GB definately isn't enough for my needs, so I ordered another 4GB stick. I installed it, plugged the machine in and powered it up. And was met with the tone for a memory error. Probably the module isn't seated correctly, but I suppose it could be faulty.
Anyway, you'll notice I said that I plugged it in before powering up. That means that the internal battery has been reactivated. I can confirm this because it will start (and give me the error) without being plugged in and without the external battery connected. So my problem is, how do I disable the internal battery again to remove or reseat the problem DIMM, since I can't get to the UEFI/BIOS configuration to disable it.

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

Sep 12, 2012

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).

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)?
