Q: T480 Laptop & Doc problems

We just purchased 20 of the T480 laptops, with 40AF ThinkPad Hybrid USB-C with USB-A Dock's. We are having several issues with these devices:The internal battery drains almost all the way down before the replaceable battery drainsThe monitors connected to the dock don't work in BIOS and pre-windows logon screen. We are unable to enter the bitlocker unlock key without using the laptop itselfThe USB ports on the dock cut in and out. You'll be moving your mouse and all of the sudden it stops moving, then jumps accross the screen. You'll be typing, and all of the sudden you'll get 10 of 1 character. This happens about every other minute or so. Sometimes the dock and laptop don't proprly recognize each other. The orange light on the dock never turns white, the laptop never chargess. The only way to fix this is the power cycle the dock. I've tried 2 different docks with my laptop, and they both have the same issues. Running BIOS 1.12, and I see the new BIOS version's don't fix any of these issues.

I recommend downloading and running Reimage. It's a computer repair tool that has been proven to identify and fix many Windows problems with a high level of success.

I've used it in the past to identify and fix everything from blue screens (BSOD's), ActiveX errors, corrupt files and processes, dll/exe/sys errors, recover lost memory, Windows update problems, defragging, malware removal etc.

You can download it direct from this link http://downloadreimage.com/download.php. (This link will automatically start a download of Reimage that you can save to your computer.)

Hi,This is the first Lenovo Laptop bought by me.I am using the laptop for a few days and the impressions are overalling good, but, I have 2 problems:The first is with the 2 battery system.I tought that the first battery to discharge was the removal battery, but that is not the case. Do I have to change something in BIOS?The second problem is with the UltraDockStation.When I have 1 USB disk connected to the DockStation, I am unable to backup laptop to USB disk, or to transfer big files (10GBs for example) (from the laptop to USB 3.0 disk). It starts normally and then it freezes the transfer.If I connect the USB disk directly to the laptop this problem doesn't occur.All components area updated, with Lenovo Vantage.Anyone has this problems and are there any ways to solve it?Thank you

A:2 Problems with new T480

I can only respond to the 1st question.  See post below.  you cant change in Bios discharge priority.  Discharge priority depends on the wear level of the 2 batteries.

I got a T480 today and it shows out that the dirve already been power on 106 times. I just got my new laptop today. I ordered it at Nov.14th and it is a T480 with 512G HDD.I opened my laptop, went through the guide, but when I ready to use, I noticed there are some films in my recycle bin that I never download. So i went to download a Crystaldiskinfo and found out that this drive's power on count is 106 count. I was gald with my new laptop. I was. Now, should I ask to change a new laptop or just ask for a new drive?

Hello to all the lenovo community. I have a T480, ( a should mentioned that I had a lots of Thinkpad these last years T40, T43, T410s, T420S, T450S, T480 and an X1 carbon...)I just love the thinkpad 14 inch computers ...  Several month ago,  I bought the T480 (great laptop),but,  sudently , some keys stop working .... (F9, F10, F11, 7, 8 ,9 , 0, ? u,i,o,p... and other keys didn't work) it was not a Windows 10 problem (driver or something else) because on linux the sames keys didn't work neither and even in the bios.  I call the lenovo support and they send me a new keyboard. The new way to replace the keyboard on the T480 is very very simple and mutch more easier compare to the t450s for exemple .. so it is a great improvment. So i change the keyboard, and it works fine. But sometimes after a several hour hibernation, it stop to work and I just cant use the keyboard , no key works.I So I have to reboot and then the keyboard works well again.  Just want to know if some of you had troubles with t480 keyboards and If you find a solution.  thanks

I'm having some major issues with my keyboard on my T480 laptop (running Windows 10). It will randomly decide that the CTRL key is being pressed as I'm typing. To the point where it's trying to paste something in my clipboard, or enable my microphone in Chrome. I've uninstalled and reinstalled the drivers for both the keyboard and touchpad, and I've run all the BIOS updates available from Lenovo using the Vantage app. I contacted Lenovo and their solution is to send me a new keyboard. But I feel that this isn't the actual issue and that it's more of a firmware/software problem. I could be wrong though. The only thing I've found with similar issues on this forum goes back to 2011. https://forums.lenovo.com/t5/Lenovo-B-and-G-Series-Notebooks/System-thinks-CTRL-key-is-pressed-when-.... This post made me think it had something to do with the touchpad, hence why I reinstalled that driver too. In that post the solutions that were worked out don't seem to work for me. Even disabling the touchpad doesn't work. The last solution in that thread was to buy a wired keyboard, which I have no intention of doing for my laptop. It's also not all the time, which is strange. It will just randomly happen and then stop. Does anyone have any thoughts as to a fix for this?

I know my laptop screen is able to display 2650x1440 because it can do it when I mirror an external monitor with that resolution but I'm not able to get 2560x1440 without mirroring. Is there anyway to overcome this so I can get 2650x1440 on my laptop screen? It's a touch screen but I don't really care about that.

Hi everyone, I have a T480 on Windows 10 , 10.0, build: 17134 (x64), with an Intel I5-8250U CPU @ 1.60GHz with 8GB RAM, bought three months ago.I've been experiencing intermitent clicking and buzzing for a few weeks when playing audio (both online and directly on the laptop).No change after updating the BIOS and putting the laptop in high performance. I've run LantencyMon, which gave me the following error message: "Your system appears to be having trouble handling real-time audio and other tasks. You are likely to experience buffer underruns appearing as drop outs, clicks or pops. One or more DPC routines that belong to a driver running in your system appear to be executing for too long. Also one or more ISR routines that belong to a driver running in your system appear to be executing for too long. One problem may be related to power management, disable CPU throttling settings in Control Panel and BIOS setup. Check for BIOS updates. " Unfortunately, I'm not so familiar with this, so I'm not sure how to fix the problem? There shouldn't be any CPU throttling on high performance so that's probably not the problem. The main source of hard pagefaults in the diagnostic I ran is msmpeng.exe and system.I've seen a few similar posts for other models, would any of you know how to fix this? Thanks a lot!

Hello,I've got brand new T480 with ThinkPad Hybrid USB-C with USB-A Dock and I'm experiencing USB issues when docked.I have read related topics and they seems to be dead without any working solution. Description of problem:When I docked my T480 for the first time, all USBs (only mouse and keyboard) were working. I had left office for night and when I have returned and docked my laptop again, USBs seems to stop working. I?ve tried to reconnecting dock, powering dock off and unplugging devices or changing USB slots without any success.Only restart of computer seemed to get USBs working back again. BUT, there have been about 5 minute period when USB devices were randomly connecting and disconnecting without any warning.Problem appeared again when I left my desk for 30 minutes without turning off or putting laptop into sleep. USBs were dead again. Only restart helped and it was followed with 5 minute period of randomly disconnecting USB devices again.All other connected devices ? 1x FHD monitor via DP, 1x FHD monitor via HDMI and headphones via front 3.5mm jack are working without any problems and laptop is charging properly as well. My laptop is fully updated via Lenovo Vantage and dock in currently at only available FW. Is there any solution to this? It?s get pretty annoying for laptop that is meant to be docked! And it seems that problem occurs accros multiple ThinkPad Thunderbolt docks.. Thank you

Hi, I"m using a T480 with Windows Hello / face recognition, but it works very unreliable.And I am not referring to the quality of recognition, but the operation itself.After a reboot, I can see the IR LEDs blinking, so I know the camera is in operation and it works perfectly.after a while (Don't know what exactly is needed to reproduce, perhaps some sleep/hibernate cycles), the IR LEDs and the camera are simply not activated on the sign in screen. Fingerprint Auth works, however, there were some cases when fingerprint also refused to work in such cases. Inside windows, I have seen several times the Window Camera Frame server taking too much CPU and  I thought it might be related, so I disabled this service. It did not change anything - Face recognition still worked for some time, and then it stopped again. I suspect this could be some driver issue. Anyone else facing such problems? Any ideas, hints? Thanks

Hi I am having trouble with my HDMI port. It no longer detects a monitor... I've been using two external monitors (one with a usb-c -> hdmi adapter, the other just straight hdmi) for a long time.In the past I have toggled the usb-c/hdmi priority in Lenovo Vantage when running into issues and that has resolved them. Now that option is not available to me and changing it in the BIOS directly does not fix anything. Any help/recommendations would be appreciated.

Hello,

for the past while now I have been having problems with the window on start up and my speakers on my laptop not working.

1-The problem started out with the speakers when I turned down the volume to nothing while playing a game and then I tried to turn it back up a few weeks later I got no sound out of the internal speakers. I tried all the options in the volume looking for anything muted with no results. I then tried to update the sound card drivers with the same results of no sound out of the internal speakers. I did try head phones as I was told by a friend to do so and I am able to hear sounds and music just fine.

2-After this first issue, I noticed that when starting my laptop I had a smaller then the normal screen when starting up, I also have this same size on my main screen. I have been able to change to a higher resolution to fill the entire screen but if I go any lower then the highest resolution I have a black boarder were the window should be.

I have upgraded to windows XP from windows ME erasing whatever information I could, hoping that a new operating program would solve this problem. But with my bad luck it hasn't changed. If you someone could help me resolve these problems I would be very grateful.

Thank you,

Hi,Recently bought a T480 with the 150MX Nvidia card. The laptop works great during normal operation during work etc but when I get home and want to play some games, nothing is working as it should. What happens is this:When I start the game everything is running good but after a few minutes I can see my CPU start to lower it's power limit (PL1) slowly towards 5W. It will stop at 5W never gaining any wattage back until i restart computer. The PL1 is at 15W when computer is newly booted. I have tried to uninstall the Intel Dynamic Platform and Thermal Framework, this results in that the processor is fixed at 15W but after a while the iGPU will go crazy and goes to 100% leaving the CPU at 2W = 0.2Ghz. And I have to restart. So this is not a valid solution. All my power settings are on maximum performance ofc.I have tried almost everything I can think of and been browsing all kind of reddit threads without any long term solution.

I ordered a T480 with the Geforce MX150 option. Was surprised to see my delivered unit with Intel UHD 620 and simultaneously active with the Geforce GPU. The Intel GPU however is the default display adapter. Intel UHD 620 is active display adapterI've never quite seen this before. Desktop mainboard BIOS would typically disable the onboard GPU if slotted with an actual video card (leaving the OS blind to its presence), and all my previous laptops that I configured with a discrete GPU would have just that alone. Am I supposed to disable the UHD 620 in Device Manager in order to force the Geforce to take over? I don't see anything in the BIOS that can influence this (in fact it seems to suggest the UHD is in charge with its shared memory setting).

In my T480 I am noticing the bottom of the laptop gets supper buring hot, and the laptop is very quite that is cooling Fan is not running.Upon trying restart the laptop, it shows 'Fan Error' in black screen and the laptop does not start.Have to hit the Power button again to start the laptop. I am affraid if not vigilent (when fan is not working) and the laptop will get very hot and damage the hardware. Started in April, (got this laptop in end of Jan 2019) and it is happending twice a week. Anyone else experincing this Fan Error issue on T480? I just check for System Updated following are being updated now:

A:T480 Fan Error

Take the laptop into your local ASP or call support for depot service, your thermal fan and fan cable connection should be diagnosed.

Hi everyone, today I upgraded the RAM and the SSD of my T480. I am absolutely not doing this for the first time and I was really careful. I removed the external battery and deactivated the internal battery before starting with the procedure. I used only ESD-safe tools and an ESD-wristband to make sure that the device doens't get damaged by static discharge.After installing the components, my device would no longer turn on. When I connect the charger, the power led flashes 3x but when I press the powervbutton nothing happens. No fan spin, no lights turning on, absolutly nothing.I then tried removing the RAM and the SSD and turning on the machine. But that didn't work as well.After that I tried removing all the power sources (internal and external battery, CMOS-battery), pressing the power button for 60 seconds and leaving the device for 1 hour before reconnecting everything. But it still can't turn it on. Do you guys have any idea what I could try to make my device work again? Thanks in advance. --resonance

Hello all, Just received my sixth thinkpad in the last 23 years. It arrived yesterday.  It is a: T480, I7-8550U, 16GB(8+8), 512 M.2 SSD, iGPU, Win10 Pro The fan is really annoying.  It goes on and off constantly.  It seems to ramp up to full speed.  I have been reading about fan noise with this model all over the internet.  Is there a way for it to run constantly at a lower speed than the constant on and off?  My previous model was a T430 never had issues with fan noise (it was very quiet too when it ran). Currently running a test:  Not using the laptop at all.  Opened 1 tab on Chrome and have it sitting on cnn.com.  Also, opened one tab on Edge also on cnn.com.  Task manager open.  Chrome uses less CPU but more memory than Edge.  CPU is running between 15% and 20%.  Fan turns on every minute or so for about 20 to 30 seconds then goes off. It is loud and annoying going on and off.  Why can't it just be a constant lower speed?  On and off is ridiculous.  If this keeps up this machine is going back. Thanks for any replies and suggestions.
