Lenovo T400 / T500 :: Memory Upgrade On Thinkpad T540p?

Aug 15, 2014

i have purchased an 8 gb Kingston Ram module ( KTL-TP3CL). My plan was to upgrade my thinkpad T540p with 12 gb of ram. My configuration is ( i5/4gb ram/hd 4600/W7 pro/500gb hdd). The thing is that I am  having second thoughts about having two modules from a different manufacturer and of different capacity.

Lenovo T400 / T500 :: ThinkPad T540p Battery Manager For Windows 8.1

Sep 3, 2014

I recently bought a Thinkpad 540p and wanted to know a way for stopping the battery from getting charged after a certain level. Its a very common feature to stop a battery from charging say after 80% and run on AC power supply directly.

Other lenovo laptops do support it, under various apps like Energy Manager, or Power Manager but I am not able to find any such options/app on my laptop?

Lenovo T400 / T500 :: ThinkPad T540p Can't Consistently Connect To Home Wireless Network

Feb 14, 2014

I just got a new Thinkpad 540p but it can't consistently connect to my home wireless network. Since a day of getting it, it was able to connect on 3 separate occasions. One being the one during the initial set up which was fine. But after that it will resort to a limited access state after a few minutes as well as with the other instances that I was able to connect. The same thing happens if I try to restart it right away after connecting. It goes to limited access. If I disconnect and try to reconnect, it won't allow me to. It prompts me to a troubleshooting step which did not work at all. I've been trying all day and night to look up solutions but with no clear one ....
This one runs on Windows 7 btw.... The wireless adapter is just a 2x2 11b/g/n wireless lan m.2 adapter... updated drivers and everything. Also, none of our other devices such as mobile phones and an HP desktop have problems connecting.

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 T540p T400 / T500 :: Can't Change Brightness

Dec 13, 2014

After 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
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.

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 T520 T400 / T500 :: 2nd HD Hard Drive Caddy Tray For SSD?

Nov 22, 2013

i want to use the DVD tray to add a 2nd hard drive using one of the many 2nd HD Hard Drive Caddy Trays i see online, but i want to use a solid state drive in it.  Can this be done? From what i ascertain via product literature, it appears that any caddy tray i see online says "accepts 2.5' 12.7MM SATA HDD only" or some such."  While there are many SSD's that are 2.5 inch, I've only seen ones that are either 7mm or "7mm (with 9.5mm adapter)."  Is there a product (either a T520-compatible 9.5mm caddy tray or a 12.77mm SSD) that can make this work?

I have the T540p and the webcam doesn't work at all. When I try using it in Skype and Adobe Connect, I just get the camera icon with a slash through it.

Lenovo T400 / T500 :: WiFi Continuously Drops Out On New T540p

Nov 21, 2014

I 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, 2011

My 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.

Lenovo T540p T400 / T500 :: After Booting Up Often Get A Blank Screen?

Dec 23, 2013

My 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.  I have to hold the power button down to shut down and then try again.  Sometimes it takes 2 or 3 goes to boot-up.  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.

Lenovo T400 / T500 :: T540p - Creating Extended Partition

Aug 23, 2014

I'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 :: New T540p - Numlock Warning At Login

Feb 5, 2014

I 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 Wireless Function Key Not Working

I am a PC technician building a Thinkpad T540p for an end user. It is running Windows 7 Enterprise 64 bit. I have installed all the drivers directly from the Lenovo support page. My problem is that the function key to turn the Wireless Radio is not working. I have checked function lock. The other function keys do their marked function fine. I have uninstalled and reinstalled the hotkey driver as well as the wireless driver and I still can not get it to work.

Lenovo T400 / T500 :: Can't Install Windows 7 - No Drives Were Found On T540p

Jan 17, 2015

I 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, 2008

I 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.

Lenovo T400 / T500 :: T540p - Intermittent Power Supply Connector?

Nov 3, 2010

Symptoms: Laptop switches off unexpectedly; unexpected failure to charge battery; random changes in brightness. Messages appear such as: "This AC adapter may not provide enough power to your Lenovo computer. Please reconnect the proper AC adapter"; "Battery 2: There is an error"; Do you want to switch to 'Airplane in-seat power plan' (if this option is enabled in Power Manager).

This is why I think the power connector is to blame: I opened Power Manager to the Battery tab and also ran BatteryInfoView by Nirsoft. With the power connector firmly plugged in at the back of the laptop and with "90W AC adapter is attached" showing in PM, moving the connector slightly from side to side often triggers one of the symptoms. The two apps then indicate that the AC adapter is no longer present and that charging has stopped. In some cases vibration due to typing or moving the laptop is enough to trigger a symptom.

Supporting evidence: After I taped the power adapter's output cable to the laptop so the plug cannot easily move in its receptacle I found the symptoms stopped (see photo).

Summary:This is a serious annoyance. It means I can't rely on the battery being properly charged when I need it, or that the machine will stay running when I leave it unattended.

I have a T540p laptop with Windows 7 installed on it, and when I insert it in the docking Station (Ultra Dock 90w) the USB ports don't work. 

I tried with another laptop setup with Windows 8.1 and everything works fine. I also tried with another docking stsation, I have the same issue. I suspect something wrong with Windows 7. 

All drivers are properly installed as the computer is new. I also performed the docking Firmware update from this page [URL] ... but this didn't work.

Lenovo T400 / T500 :: System Image Migration / Restoration To T540P?

May 26, 2014

I have previously done a system image of to T500 OS and everything. The T500 is on it's last leg. I received a T540P as a replacement but I want to migrate the T500 system Image to be restored on my T540P.
I know it's doable because I have done it BUT the problem is, I think the downloads. It seems when I go to update software after the image is done the T540P downloads. (the Lenovo PM, Graphics and Display drivers) when the reboot happens I get to the Startng Windows screen and the 4 bubbles coming together and then pulses. But it always says there. It at least, I stopped it after like a 30 minutes.

Lenovo T400 / T500 :: T530 Full Disk Encryption - Hard Drive Password?

Jul 24, 2013

I just received my T530 (2359CTO) and need to encrypt the hard drive. When I purchased it, I opted (among other reasons) for Windows 8 Professional because it comes with BitLocker. I then discovered that some ThinkPads have hard drives that support hardware encryption (FDE).
I've tried to figure out whether mine has this feature, but haven't had any luck. The BIOS gives me the option to set a hard drive password, but I'm not positive that it actually encrypts the hard drive with this setting.

a) how to figure out if my hard drive supports hardware encryption
b) how to enable it
