Hi guys, I love my Lenovo and recently, after a mobile broadband outage, I mistakenly squeezed the 4G sim card just above its slot. It got lost inside the laptop and short circuited the motherboard. I opened it, voiding the warranty, and then took it to a private service. They replaced the mobo, but now when I start up the laptop it gives me two errors, 2000 and 2001 (machine type and serial number are invalid AND machine UUID is invalid). To boot, the Lenovo support website won't recognize my device. Any help, please? I've disconnected the hard drive, batteries, reset the laptop with the pin, defaulted the BIOS, nothing works. Those 4 beeps at the beginning of the startup are annoying. Thank you!

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.

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

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.

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 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).

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.

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

After perusing this and other forums looking for a definitive answer, there seem to be dissenting opinions on whether using the drive caddy and adapter cable in the HDD bay will allow 2280 M.2 NVMe SSD drives to utilize all 4 PCIe lanes.

I don't have one to test, but the platform spec for the T480 says that some of the T480 machines have SATA drives and some have this: "M.2 SSD / PCIe NVMe, PCIe 3.0 x 4"
 
To me, that means is should use 4 lanes

Hi Folks,I am looking at a new T480 (not T480s) as a potential work replacement.  I have used Thinkpads off and on since the late 1990s, and am currently using a T460.  I am a Linux user (Ubuntu).I see from specifications listings at Lenovo that the T480 has two (??) SO-DIMM memory sockets.  My T460 has one, and also has RAM soldered onto the Motherboard.  I would like to verify with another T480 owner that it does in fact, have two SO-DIMM sockets rather than one DIMM socket plus on board RAM.https://psref.lenovo.com/syspool/Sys/PDF/ThinkPad/ThinkPad%20T480/ThinkPad_T480_Platform_Specificati...Some of the T480s (specifically the i7-8650u model) have a Nvidia GPU.  I don't need this GPU and see it as something that really could just add battery drain without any benefit.  Can I just remove this GPU?  I see tear down videos of T480s models and it looks like it could be removed altogether.Thank you for any help.  In spite of being slightly larger and heavier than my current T460, the new T480 looks like a power user's dreams come true.  Just need to confirm the two things above to finalize my decision.

I have been having issues with my battery on my T480 lately. I will have the laptop running around 50% battery and sometimes try to restart it but when I do, the laptop will not power back up. The Lenovo bios screen will post but when the Windows 10 circle starts spinning the computer fully shuts itself off and loses power and I cannot turn it back on until I plug the charger in, but when Windows loads it says I have battery. Yesterday I was using the laptop and when it went from 50 to 49% battery the laptop fully died and shut off and would not power on again until I plugged in the charger, yet showed 49% battery when Windows loaded again. I have been working out in the cold with my laptop and I am not sure if that is or has affected it some how but I can't keep having these types of issues when I need to be able to use my computer in the field. I know Lenovo used to have a tool to reset and deplete and recharge the battery, does this still exist? I ran the diagnostic tool but it finished instantly saying both batteries were fine with a time on the diagnostic of 0 seconds. Not sure if there is another tool I can be using to try and get this working properly again.

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.

The laptop has a single HDMI input socket and I don't want to plug 1 monitor into the C-usb port and other into HDMI.I do not have a docking station and assuming I won't get one soon. Can someone suggest an adaptor or suitable product I can use, even better if you can include a link to the item!Thank you in advance,  Jack
