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

I'm trying to connect my T480 to an external display using the left side USB-C ports. When I plug in the external monitor using a (USB-C to DVI cable), Windows 10 displays an error message like: "USB not recognized. The last USB device you connected to this computer malfunctioned, and Windows does not recognize it". According to T480 user guide those ports should work with an external monitor, so is this a hardware issue? All drivers are up to date.

I've noticed my fan always stays on regading the temps when my machine is plugged on the 65W charger, temperatures remain between 38 and 57 on light use, but even when idling the fan kicks on as soon as I plug in my charger and turns off a couple seconds after I plug it off. I have tried to fix it by installing the patch mentioned on https://pcsupport.lenovo.com/es/en/solutions/ht506625 and changin the BIOS profile for the plugged status (it's on the same profile now both for AC plugged and unplugged) but the problem perists. Anyone knows how to fix this issue without the need to install 3rd party software or can point me to the windows 10 settings that regukate this behaviour? Thanks in advance.

We have an associate who uses a T480, he has dual screens and we have an HDMI and USB C to Hdmi for his displays. Most of the time they are running fine, sometimes though the USB C one goes black, and he has to unplug and replug it back in. Then it wakes up, we have replaced his USB C adapter and cable to the monitor and it hasn't helped. Is there possibly some settings that turns off the USB C port after a time period? It's hard to pin point because it happens throughout the day. Any help is appreciated.  Thanks in advanced.

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.

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).

Hey! I was wondering any kind of SSDs would work with the T480? Right now I bought it with 500 GB HDD and Intel Optane (16Gb), but in the future, I might consider upgrading to 512 nVME SSD for system. Also, what do you guys know about the battery life upon general internet usage? I bought a battery with 72Wh so in total it would be 96 Wh. Plus, I also own a Varta Power Bank (13mAh) 48,1 Wh. Do you guys believe it could charge the battery by any chance? https://www.varta-consumer.com/en/products/portable-power/overview/details/lcd-power-bank-13000 Please let me know you guys think!

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.

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

Hi, the display of my T480 that I bough in November, 2018, has scratches from the keyboard and the pointer that appeared after closing the lid. I always carry my laptop in a sleeve and a "slip" between the keyboard and the display (otherwise the scratches could have been even bigger!). I thought that I'm buying a business-product for 1500? that will accompany me for a couple of years during my work at the University. Unfortunately, the scratches are really annoying, and the notebooksbilliger.de told me that it is a purely "optical" flaw, not subject to warranty, and if I really want to, I should contact you in the first place. Which I am doing, because I find it really disappointing of Lenovo, as I bought your laptop due to your excellent reputation. The scratches are definately there because of the construction of the laptop. What do you say about that? Karolina Video: https://drive.google.com/file/d/12helGfqJ0AdEgj2yxzTbUlJGdKrxztLX/view?usp=sharinghttps://drive.google.com/file/d/190jL1109FsM4NOmVPGx8rVBso7dTqsfc/view?usp=sharingFoto: https://drive.google.com/file/d/190jL1109FsM4NOmVPGx8rVBso7dTqsfc/view?usp=sharing

I've been having fun with the new T480, except for a problem with the trackpoint. I don't use the trackpoint for much, but I do use its buttons at the top of the touchpad. I noticed that the buttons were not working, which led me to try and see if the red stick was working. When the buttons stop, the red stick stops too. The trackpoint will just stop working, and I can't see any pattern to what causes it to quit.  I was worried that it was a hardware problem, and it might be, but if I go to the settings and disable, then re-enable the trackpoint, it usually starts working immediately. The computer is only two weeks old, and is under warranty, but being without it while I send it in for service is far more expensive to me than buying new parts and installing them myself. But is there a good strategy for exhausting software problems first? The Lenovo vantage update system seems to think everything is up to date. While I've been composing this post, it has started and stopped working twice.

I've got a 2 month old T480 that intermittently, but frequently, refuses to shut down. It just spins at the Windows 10 shut down screen. After updating all available Windows and Lenovo updates it still occurs. Recently the battery occasionally stops charging. Removing and replacing the battery seems to resolve until the next time. This has only happened twice in the last week or so but I'm not sure if this is a related symptom or something else entirely.  I've got an X1 Yoga that has also had similar issues shutting down but very rarely.

Using the trackpad on this T480 (i5 8350u, mx150, 16gb) results in jumpy cursor movement, especially at low speeds. It doesn't really hinder the usability but it's definitely not smooth. Is the trackpad just *like* this? Or do I have a dud? What I've tried to troubleshoot: This isn't a screen issue because my wireless mouse tracks very smoothly.I'm on the latest intel + nvidia drivers on windows 10 1803 (latest updates).I've also tried using the trackpad on ubuntu live usb and it is also jumpy there -- so is it definitely a hardware issue? Any ideas?
