Lenovo T400 / T500 :: New T540p - Numlock Warning At Login
Feb 5, 2014I have a new T540p and I have an issue with numlock when logging into the computer. (This is NOT the numlock on-screen display icon). Basically, whenever I get ready to type my password in the login box, it brings up a warning that my Numlock is on and that "your password may be entered incorrectly".
I understand the need for this warning on keyboards without a separate numpad, but my T540p has a full-size keyboard with a separate numpad PLUS I am using an external keyboard. This error comes up both with and without an external keyboard.
This wouldn't be a problem except that this warning is especially aggressive and never in the same spot twice, and will sometimes even entirely cover the username AND password field with an ugly black box.
BTW, this is Windows 7 Pro (purchased downgraded from Win 8). I just can't figure this out, it's gotta be something with the Lenovo software but I can't find it.
Lenovo T400 / T500 :: T540p - Fingerprint Reader Not Working Upon Waking From Sleep For Windows Login
Mar 11, 2014I have a brand new T540P with a Validity fingerprint reader.
Rougly 80% of the time, the Fingerprint reader is unresponsive at the windows login screen after waking the computer from sleep. It works 100% of the time when booting from an off position, however. Once logged in, it also works 100% of the time. The issue only arises when logging into windows.
Things I have tried
-uninstalling/installing device in device manager and finger print manager pro software
-setting fingerprints through both fingerprint manager pro software (lenovo) OR through the built in windows fingerprint control panel options
-disabling "allow windows to turn off this device to save power" in device manager.
I should note as well that I have another T540P that I ordered as a replacement. Both models experience the same issue.
Is this a platform wide issue affecting all T540P models?
Lenovo X / Helix Tablet :: ThinkPad X230 Login Screen Not Appearing - Black Display With Cursor
Jun 21, 2013I have a ThinkPad X230 Tablet. I tried system restore and safe mode, but none of it works.
After windows loads with the glowing animation, the login screen does not appear. I cannot open a task manager. I don't know if it's a problem with explorer.exe or what.
The explorer.exe crashed when I tried to connect to an external hard drive, and I tried to get task manager to open, but it wouldn't open.
That's when I tried to restart computer, and login screen would not appear. All I have is a black screen with cursor.

Dec 23, 2013My T540p with Window 7 is experiencing problems starting and shutting down. After booting up I often get a blank screen where just the moused pointer is displayed.

Quite often when I shut down Win 7 The desktop icons disappear but the desktop background continues to be displayed and the notebook doesn't shut down.

Dec 13, 2014After updating my Thinkpad T540p, I cannot adjust the brightness in anyway. This is a problem because the screen is too birght and eats up battery.
It appears the only way to adjust the brightness is to use Intel HD Graphics, which isn't so convenient.
Fn keys don't work. changing the brightness on the Power Manager settings doesn't work. There is no brightness option on Windows Power Manager.
I have Intel HD Graphics 4600 10.18.10.3960
I have Lenovo Power Manager 6.66.3
Edit: In fact, I think it's posisble that Power Manager to just outright no longer works.

Jun 7, 2013I 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.

Nov 21, 2014I have a two month old Lenovo T540p with win 8.1 and a Realtek 2x2 1 1b/g/n wireless Lan M.2 adaptor that loses the connection to all wifi every 10 minute. The wifi worked fine in the beginning, but after a month and some updates the problem started.
Lan cable works without any problem.
I can always fix the wifi with turning off all wifi ( t. ex. fn+f8) wait 5 seconds and turn it on again. But after aprox. 10 min. it drops out again.
Every part of the laptop is up to date, even bluetooth driver, bios etc..
I tried another router same result. I tried changing channel on the router.
I tried connecting to a hotspot on my smartphone, same result.
The distance to the router makes no difference.
The Laptop is scanned for virus with Avast free.
I use chrome but tried IE and mozilla with the same result.
I tried to ping the router and it receives no data when the connection is lost.
I tried turning the firewall off, same result.
There no power saving on wifi.
Everything is fine in device management
Maybe its a win8 issue ? Do I really have to format the hd turn the computer back to beginning and start all over ? This shouldn't happen to a brand new computer.
Lenovo T400 / T500 :: IE 11 Asks For Windows Password On New T540p?
Mar 11, 2011My new T540p came with IE 11, and from time to time, I get a bar across the top of the big window where it's asking me to type in my *Windows* password. Not for whatever site I'm on, but my WINDOWS password. My year or so older T440 does not do this, nor does my non-Lenovo work IE11. There's a red cirle in the far right of the bar, with a "voice balloon" with 4 Xs.
The machine is virus free, but why I'm getting this prompt ONLY in the browser.

View 3 Replies View RelatedLenovo T400 / T500 :: T540p - Creating Extended Partition
Aug 23, 2014I've just bought a t540p thinkpad and started migrating to the new machine with my all stuff from the old one. Unfortunately I've encountered a problem which I cannot resolve by myself.
I've got preinstalled Windows 7 which came with 2 partitions for itself - system_partition and os_files. After them there are 2 more primary partitions: Lenovo_Recovery and hibernation partition for 30-day standby.
I really want to rearrange these volumes so I can divide the files betweend OS C: partition and D: partition for my data. The problem is that there are already 4 primary partitions at this disk which is the limit for MBR so I can't create any more.
I've tried to boot up a linux mint live usb with gparted, but the system didn't start. Probably some UEFI issues which I cannot afford to deal with now.
So my disk looks like this at the moment:
- system_drv - 1,46 GB - system, active, primary
- os - 60 GB - bootable, pagefile, primary
- unallocated - 154,25 GB (space for D: partition which I got from shrinking OS partition)
- lenovo_recovery - 15,76 GB, primary
- (no name) - 7 GB - hibernation partition, primary
So, is there any possibility to change the volume with OS partition to the extended one and create second logical partition for my D: partition? Or maybe there is a way to change hibernation partition to the extended one?
If both options above are not possible I would be grateful for specifying the steps to fully disable the 30-day standby so I can delete hibernation partition (however the 7 GB at the end of disk will be unused then because I still won't be able to attach them to C: or D: partition). I assume that simply unchecking the option in the Global Setting of Lenovo Power Manager won't be enough.

Lenovo T400 / T500 :: Can't Install Windows 7 - No Drives Were Found On T540p
Jan 17, 2015I have lenovo ThinkPad T540p. With Intel Core I7, 8gb RAM and 500gb HDD. I think my HDD is Toshiba. There was Windows 7 on it but it won't boot on it anymore. When I start Windows it shows 5 second black screen and then it shows Boot Menu. Well, I tried to reinstall Windows but when I have to select on which drive to install Windows I've got an error: "No drives were found". And the list with drives is empty, so I can't reinstall Windows. I updated BIOS but it didn't work. Finally, I formated my HDD and created two partitions on it. It worked, but not for a long time. I installed Windows 7. Everything was fine until I restarted my computer. And then I've got the same problem: "Can't boot from HDD" and it shows Boot Menu. Then I started Windows installation and I've got the same error: "No drives were found".
I don't understand what's going on with my HDD and what's destroying it's partitions.And I don't think that my HDD is broken.
Lenovo T400 / T500 :: T540p With UltraDock USB - Plane Mode Has Been Initiated
Oct 13, 2008I have the T540p with Win 8.1, actual drivers. Updates as in the web site. It works in the Ultra Dock with a 135 W power supply.
Attached to the Dock are following USB Peripherals
1) MS Keyboard 4000
2) Ms Mouse
3) Web Cam (Logitech 920)
After some time (sometimes 10 Min after booting, sometimes longer), the USB ports do not work. Unplugging the peripherals and plugging them into other USB ports of the dock does the trick, but the previous ones do not longer work until the next start.
The Screen goes blank. Sometimes but not always I get a message from the power manager stating that plane mode has been initiated due to power supply problems. I have tried connecting the thinkpads own 135 w supply, but no difference.
