So, I just got my shiny new T540p with a 3K display and Win Pro 8 installed. I promptly upgraded to Win 8.1 Pro and now I have a problem with the Intel HD Graphics. Basically, the system will not turn the display on after a sleep and I can't adjust brightness.
I tried downloading the drivers from the support page, but they reference a Intel(R) HD Graphics 5000 card, whereas my system says it has a Intel(R) HD Graphics 4600 installed. When I try to run the driver install anyway, I get a message saying that my system does not meet the minimum requirement for installation (?).
I tried manually installing the Intel(R) HD Graphics Family driver instead. This fixed sleep and brightness control, but then all things 3D was completely messed up (like buttons in Skype and Chrome).
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. I've read in other forums that uninstalling the webcam driver and reinstalling it doens't work. I really need the webcam to work so this is pretty urgent for me.
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.
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.
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.
I bought a T540p. It came with windows 8. I tried to install windows 7 pro 64 bit. It now hangs on the starting windows screen and I can't get to the desktop. how I can get it to work? Are there any bios settings that need to be different for windows 7?
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.
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.
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.
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.
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.
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.
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?
I recently bought a Thinkpad T540P laptop. But there is always some noise made by the hard drive. The noise makes me feel uncomfortable. It sounds like it has been used for a long time, but actually only two days.
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 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.
Windows 8.1, 64bit, all drivers up to date, Nvidia 730m, intel 4600. Fairly new issue (couple of months), laptop wakes from sleep but display does not function, everything seems to be working normally during, just no display. Forced to hard restart.
Just avoiding using sleep mode for now. Seems to be a software issue, upgraded to 8.1 when purchased almost a year ago, worked fine until recently.
My problem is that when I'm connected with the t540p to the ultradock that this sound comes from the local speakers instead of through the HDMI cable though the monitor and then through my external speaker which are way better. In the Sound playback devices I have written: "High definietyion Audio Device Not plugged in".
So I tried connecting directly via laptops mindpoit to the monitor and then it worked. But as soon as I connected it to the docking station which is also connected to the same monitor via DVI plug then it results as Not plugged in.
So I tried upgrading the dock station firmware by downloading the fwdphb03 latest firmware, and this does not launch despite being connected to the docking station and using an external monitor and properly plugged in.
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.
I 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?
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.
On my T540p, I configured the rapid start technology according to [URL] ....
Since I have performed a BIOS update to 2.14 and an update of the Intel Wifi driver to 17.0.5, I experience the problem of battery drain when the computer is in S4 sleep state, at a rate of approximately 0.125% per hour (on the 56Wh battery).
This was not the case before these updates. There was no noticable power drain in S4 sleep state, even not over multiple days. I'm using Win7, I set all the WoL capabilities both in BIOS and in the Intel driver to disabled, according to [URL] ....
External device USB charge settings are also fully disabled in BIOS and Power Manager. The problem does not occur when the system is fully shut down, but in S4 Sleep state, which should be a zero-power state too, as it was before the updates. In the details of the BIOS update it is stated " Fixed an issue where the computer might fail to enter sleep state". Could the power drain be a side effect of this fix? Or is it an issue with the (new) Wifi driver, as it was the case for the Y410P?
