Lenovo T400 / T500 :: T420 Takes 20 Seconds To POST Screen After Pressing Power On Button
Sep 18, 2013
My T420 takes about 20 seconds from pushing the power on button to the Lenovo POST screen. After that boot takes about 30 seconds to Desktop. What bothers me is this long wait until I see the POST screen. It doesn't seem normal to me.
My System is setup with Windows 7 64bit booting from UEFI on a mSATA Crucial M500 SSD. It has 16GB of Ram and a i7 CPU. I have the newest BIOS (1.46) installed.
Why it takes this long to reach the POST screen?

Just to clarify, my laptop is a Lenovo ThinkPad T420i, Type 4178. It is about 2 years old. I have Windows 7 64bit.
My laptop takes about 2-5 minutes to switch on, sometimes it doesn't turn on at all. The screen freezes every 15 seconds or so, but I am still able to move my cursor around. It also lags quite a bit. For example, typing 'how to download google chrome' will take me sometimes an entire minute, because only parts of the sentence will show up on the screen at a time. My keyboard is responding fine. The problem is not with the wireless internet, because even when the wireless is off the laptop is still unbelievably slow. Watching videos is impossible, because the screen freezes so much.
I have been having this problem with my laptop's performance speed for about 2 months now. I had it completed wiped back to factory settings, downloaded every malware and virus scanner known to man (none of them found any problems with it) and updated all my drivers.

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...

Ever since i've wiped the machine, i've been having these two problems. When I close the lid, it used to go to sleep straight away, but now I can see the sleep light (and the power button) flash and flash, then it goes to sleep.
When waking up it goes through the lenovo startup screen and resuming windows, then it asks for a password, before I used to open the lid and it would ask me for the password straight away. I know it was going to sleep because I could hear the beep straight away when I closed and opened it, but now it just takes too long.
Also, everytime I boot up into windows or resume into windows from a sleep state, I can hear the device noise, like something is being plugged in/out. But there is nothing being plugged in or out at the time. I can't get to device manager quick enough to see what it is that is causing it. But all drivers seem okay.
Also noticed, when the lid is closed, randomly the laptop turns off (hear the beep) an then turns back off again.

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.

I had an admin power on password on a T420 that contained a character that isn't allowed in the newer version (old password had a dash - in it) and I didn't remove the password prior to update so now I can't get into the BIOS as admin - are dashes changed to something else during update or can I revert back to a previous bios version (if so where are they located)?

I've been trying to set-up a second hand T520 bought without the original hard drive. I've installed a Samsung mSATA SSD. I tried to use a set of recovery discs produced on my T510 which seemed to install but got BSOD whenever Win 7 tried to boot. I then downloaded the Win 7 ISO and booted from the DVD to try and initialise a repair which would not initialise. I next tried installing Win 7 Pro from the Win7 ISO disc which succeeded but ran into problems with unrecognised network components and drivers.
I've gone through this whole cycle again and got to the set-up screen for Win 7 then got distracted; my thinkpad then appeared to have gone into hibernation before I could finish set-up. Unfortunately, when I try to power up I get a few flashing lights for a few seconds; no POST bleep and the power dies. I've tried pulling and reinstalling the RAM and SSD but to no avail.

I'm tried hard-booting the device, but no dice. When I push the power button, I show activity in the status lights and can feel heat coming out of the heatsink. I think I see the 'ThinkPad' screen displaying very faintly at that time, but it seems not to proceed through the regular boot process. I'm definitely not able to get to a BIOS post.

I have a T530 with an SSD, less than a year old, that appears to be bricked ... when the power button is pushed, there is absolutely no noise (no fan, no beeps) and no indicator lights.
I'm having trouble getting the "what happened" story out of the user but I heard something like "the battery ran out and now it won't start". I suspect some improper behavior like hauling the machine around when it was "sleeping" (not off) but that as they say is another story.
Elsenet I saw the following "one weird tip" to discharge static buildup (*)
* unplug power
* take out battery
* take out RAM
then a sequence where you pushed the power button 9x and on the 10th time held it for 30 seconds. Then plug power in and try again. No soap (although the ram is internal, not in the expansion slot, so I haven't disassembled the keyboard area to check).
I also unplugged the battery/power and held down the power button for one minute - still no luck
Swapped out power supply and battery - no luck
Only indications of "life" are the little battery icon on the top of the case (e.g. when computer is closed):
- Battery not installed - put power cord in, icon flashes green 3x, stops, but power button does not turn on
- Battery installed - put power cord in, icon flashes green 3x, flashes long orange 1x, flashes short green 1x more
Is there something else I can try or is this a "Call IBM/Get this guy a loaner"?
* laptop appears to be staticy, I have gotten a couple of "snaps" off it, and that doesn't regularly happen

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.
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?

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.

I have been trying to install a new version of windows on my T420s laptop but have been unable to get the system bios to allow me to select the USB jump drive. I have tried a number of different BIOS setting trying to get the drive to show up in the F12 boot list. 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.

my 4-in-1 card reader (04W1701)is on the fritz, can't find any on ebay, but there are plenty of '5-in-1' (FRU 45M2658) to be had. Can I use that instead?

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?

I have a new Thinkpad T430 and I have an issue with the touchpad. My touchpad is disabled while holding a key on the keyboard which is extremely frustrating. If I hold down a key then my pointer will move a short distance before stopping and becoming unable to move any further until I release the key. I've learned that this feature is know as the palmcheck feature of the ultranav drivers. However, in the settings for my touchpad, there is no palmcheck setting. The feature seems to simply be on with no option to turn it off. I have updated to the latest drivers, but still there seems to be nothing I can do to fix this issue.

I have multiple T430's at my company that are slow to shutdown. It takes approximately 10 minutes to shutdown. It is also consistant, as soon as you login and shut down it will take that long. These are all installed using an image. Running windows 7 64 bit. Looked in event log, but no indication of abnormal errors. Using Kaspersky, Office 2010, Mozy. Checked some registery settings on microsofts website but that didn't fix the issue either. Not sure if this is a lenovo problem, or a windows problem or a conflict with other software.

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.

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?
