T480 fan always on on AC

Q: T480 fan always on on AC

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.

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.)

Another similar question, is it possible to install more RAM into the T480?  It comes with 16GB, but are there sockets available to install another 8GB?

Depending on how your machine shipped, you may have a single 16GB stick and an empty socket, or two occupied sockets.

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.

T480 doesn?t charge with the USB-C AC charger plugged in. when the AC charger is plugged in, the orange LED illuminates and blinks three times, the plugged in logo pops up momentarily then nothing. The thinkpad was purchased in October this year with everything working flawlessly... I then left the standard 45W charger at an airport. I ordered a replacement and received it 6 weeks ago and has been working fine until today... Do I have a dead AC charger? anyone have similar issues?

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!

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).

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.

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 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

My organization has recently purchased a number of T480s laptops and we have been experiencing a problem where the laptops are freezing when they are removed from the dock. We called Lenovo support and they told us to open the laptops before we dock them.For the full story:We have 2 external monitors connected to the docks so users leave the laptop closed when docked.Often, a user can put the computer back on the dock one monitor will work but it mirrors the laptop screen. The mouse/keyboard won't work on the dock but the trackpad and laptop keyboard will work. I've seen those components begin to work again after 10 minutes. All of a sudden the other monitor will turn on and then the screens will work properly.It almost feels like the dock is taking 10 minutes to realize that the computer has been put back on. We have been updating the firmware but it doesn't help.This doesn't happen every time but it is sporadic. Has anyone else seen similar issues? Thanks,Paul

HelloAs many others have described in other posts, my trackpoint is not working.It sometimes works when I go into advanced boot options, and when I do a hard restart (unplug batteries, or reset bios to OS optimized defaults) it sometimes starts working again for a small period of time. Then it can stop working, either after a hibernation, but also just in the middle of using the computer. (I was watching netflix I think when that happened)What is the best cause of action?Everybody seems to agree, that it is a BIOS issue, as the problem often persists to other OS's.I would rather not open my computer, however I can and have done that in the past with other thinkpads.If I send it in to lenovo, what will they do to fix it there? And can I just do that from home, with a set of small screwdrivers?

Hi guys, I am planning to purchase the T480. I am a Linux user, therefore, I will be installing Ubuntu 18.04. I will use VirtualBox to run a windows system which will be used to do word, excel, visio stuff. This will run through out my work day. Apart from that, I will also be spinning up other ubuntu VMs to run / test software and apps occassionally. The config I have in mind for the T480 is as below:- Intel Core i7-8650U Processor (8MB Cache, up to 4.2GHz)14.0" FHD (1920 x 1080), IPS,Anti-Glare,250nit32GB(16+16) DDR4 2400MHz SODIMMIntegrated Graphics (Intel UHD Graphics 620)1TB Solid State Drive PCIe-NVMe M.2 2280 OPAL 2.0 So I am opting for the integrated graphics as I will not be playing any games or doing any graphics / video editing related stuff. Also so that I can save on battery consumption. However, I also notice that if I opt for the MX150 graphic card instead, there will be 2 heatpipes resulting in better cooling system. So, I would appreaciate some advise on this. Is it ok to go with the intergrated graphics with the work I do? Will the system heat up if running multiple VMs ?Should I invest on the MX150 for better cooling ? And will there be significant usage of battery with this ?Overall, what is the advise. Also, if I should be patient and wait for the T490 assuming it will be launched in Jan / Feb 2019. I've used the x240 before and I did experience massive heat on the bottom of the laptop.  The X1 carbon 6th gen i...

I have a US model T480 and will be traveling to the UK. In the past, I've taken my MacBook Air and Dell XPS to this country and was simply able to purchase an adapter and it seemed the power brick did the conversion to the right volts. However, this is a new laptop and I want to make sure this will be the same case for my Thinkpad. So, has anyone taken their Thinkpad to the UK and have things work fine or should I just buy a converter? Thanks
