T480 Will not boot with a USB Mouse or Keyboard plugged in, Laptop or Dock

Q: T480 Will not boot with a USB Mouse or Keyboard plugged in, Laptop or Dock

When we have a USB Mouse and or Keyboard plugged into the laptop or the ThinkPad Pro Dock (M3F00) it will not boot, it will boot however if we turn off the USB UEFI Bios Support off, then we will have to use the laptop keyboard to logged in. Then the external mouse and keyboard will start working after that.How do we get this to work with the external keyboard and mouse. Seems to be a hit and miss issue with our organization.Added note...Mcafee Endpoint Encryption is also installed, and the system will lock up either before or at the McAfee login screen.

Preferred Solution: T480 Will not boot with a USB Mouse or Keyboard plugged in, Laptop or Dock

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.

Hello.I`ve got Lenovo T480 with some problems.1 : After undocking and using laptop for some time the blank screen just shows and nothing you cant do, only do a HARD SWITCH OFF, and then switch on again. After that is ok. I`ve got it 2 times, laptop is no more than one month old. There is no specific way when it shows, just unplug the dock, have some apps turned on and BOOM, blank screen and cant do nothing but hard switch off. 2. When i`ve got plugged USB -C Dock from Lenovo to T480 it doesnt see a network via Ethernet cable, anything else is working good with dock (i mean external screens or some USB stuff) but only network is not visible by T480. Windows 10/Updated drivers and BIOS as wellMaybe some Lenovo stuff just crashes it? I mean Active protection or something?Cheers

I'm using a Razer Trinity mouse, and it works fine, as long as I plug it directly into the laptop's USB port. If I try to use any sort of USB hub or switch (I've tried three different hubs -- each with a different set of USB cables) the mouse cursor randomly freezes on screen for about one or two seconds at a time. I tried installing the Razer Synapse 3 software on the laptop, and turned off the mouse lighting (to reduce power usage and rule that out), but that didn't help. I've also: -updated all drivers/bios via System Update-installed all Windows Updates-tried all three Windows power profiles

Hello all. I have a user with an older X1 Carbon (Machine Type34443444GYU) and a ThinkPad USB 3.0 Dock (basic model from what I can see). They've been using it for over a year at the very least but for the last couple of weeks their wired keyboard and mouse on the dock just lock up. The keyboard and touch pad on the laptop work fine. Undocking and redocking do the trick but this happens several times a day with no rhyme or reason. I've run virus scans, hardware diags, done some cleaning on the system, updated all the drivers I can find and I even swapped the entire dock and all of it's cabling for the same model. We had a spare that had never been used. I reinstalled the dock drivers fresh. The only thing I have not had a chance to do is to update the chipset which I saw was availble via Lenovo updates. I intend to do that as soon as I can get access to the system again. If that fails to help does any one have any ideas at all about what to try? Thanks!

So I just got a brand new Lenovo Thunderbolt3 Dock Gen2 to use with my lovely T480. The dock works ok but I have a big problem everytime I put my laptop to sleep at the end of the day. In the next day when I wake my machine (by pressing the power button on the Gen2 dock) my system wakes up fine but my external keyboard doesn't work.I have to reboot my laptop to get the keyboard working again. Anyone have dealt with the same problem with Lenovos docks? All drivers and firmwares are installed from Lenovos site and the Thunderbolt3 software (the older app not the new UWP) sees the dock fine. Tried to unplug and plug back the USB keyboard but still it doesn't recognize or work.

I have a new Thinkpad T480 docked to a new ultra docking station.  I have a new Logitech M500 (corded) mouse plugged into a USB port on the docking station.  As I am using the mouse, the cursor will sporadically "freeze" on screen for a couple seconds and then go back to normal.  This will happen frequently as I am using the computer.  Very frustrating.  Substituting this mouse for a Logitech MX400 yields the same results.  If I instead plug (either) mouse into the laptop directly (instead of the dock), the issue is does not occur.  Any ideas as to why this is occuring and what I can do to fix it?  I have already installed the latest updates from Lenovo Updater and for Logitech Setpoint as well. Thank you,CJ

I purchased a A485 and worked well but quickly replaced Mech harddrive with SSD. After reinstalling windows 10 I noticed I loss the function of the backlit keyboard, as well as my mouse cursor kept freeze when using the Track point when I would use the middle button for scrolling. all drivers up-to-date and even tried reinstalling windows and drivers again...still have this issue the mouse freezing is the must fustrating since I primarily use the Trackpoint to control my mouse functions. I found that locking (windows + L) and login back in frees up the mouse again...but typically freezes shortly after pretty fustrating, especially when one of the main reasons I buy Lenovo is their trackpoint. I've seen people have similar issues but no resolutions in their threads.

Hi Guys,
i installed the D3100 dock on my XPS 13 and everything works fine, until i had some kind of update on windows10. After this, windows shows the message "display link core software is not available anymore on your pc". I've updated the driver, re-installed the displaylink driver, but since that upgrade, the mouse and the keyboard started to lag in a pretty buggy way.
If i use the laptop without the dock everything works fine.
I'm using Dell wireless mouse+keypad.
Any suggestion?

I am not sure if this should be on here or on the peripherals section of the forum.
I own a XPS 13 laptop and type c dock, I have erratic mouse movement and keyboard issues from these external components when used through the dock via the USB ports.  If I leave the laptop slightly open the issues go away.  Also if I plug them directly into the USB ports on the laptop I also get no issues. This is my current work around although for a brand new laptop and dock having to plug in 3 things rather than just the docking station doesn't make much sense.
I have tried the keyboard and mouse on other PC's with no issues.

I have a Dell XPS 15 9560 laptop that I've updated with the latest BIOS and drivers.  I also have a Dell TB16 240w dock.  I recently bought a Sonnet Echo Express SE1 TB3-PCIe Chassis where I've installed a 10Gbit Ethernet card.  When I plug the Sonnet Chassis directly into the laptop, the laptop sees the network adapter perfectly, but if I plug the dock into the laptop and the Sonnet into the dock, it fails to see it (the network card).  Any ideas??
I can plug the Sonnet chassis into my laptop and plug the dock into that, but then I lose the ability to charge my laptop via the TB3 cable.  Not ideal.

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?

(As a preface, some of this has to do with me installing Linux on a different drive, but I'm pretty sure it has nothing to do with the problem, which is with Windows 7 behavior, so please bear with me)

I recently bought another SSD in order to install Linux on it, so that my current SSD with Windows 7 will remain the same (so I can avoid partitions and stuff, and SSD space is scarce). I also have a separate bigger HDD with just data.

I can successfully install Linux Mint on the new SSD, but whenever the new SSD it's plugged in, Windows 7 won't detect my keyboard or mouse. I tried every available USB port to no avail. I can't even log in.

The thing is, if I then shutdown, remove my new SSD, then boot back into Win7, then both keyboard and mouse work (I'm in Win7 right now). It therefore does not seem to be a driver issue, since it worked previously and it still works with this hardware change. It's like windows detects that something is not as usual (the new SSD) and decides to ignore every hardware it can, to my despair.

I've been here four afternoons trying different permutations of installing linux, plugging drives in different places, and nothing. I don't know what to do anymore.

In case this is relevant: Right now I installed Linux on my SSD with the other two drives unplugged, then plugged them back in, and for now, I choose the OS to boot via BIOS (hold F8 and choose), no GRUB or anything yet. That will come later when Win7 works by itself with the new SSD plugged ... Read more

A:USB keyboard or mouse not detected when a new SSD is plugged in

Some additions:

I can boot into Linux and it works perfectly, both with the other drives plugged in and not, so it doesn't seem like a BIOS thing.
I reset the BIOS settings to default yesterday and it did not help unfortunately. It seems to be a Windows thing.
The system is not frozen at log in, I can see the textbox caret blinking and when I press the power button on the computer (just press, not hold) it detects it and shuts down properly. So it is not recognizing keyboard or mouse, it's not like it's frozen.

I have an XPS 13 9360 connected to the WD15 dock. I've noticed that regularly the external mouse and keyboard I have attached to it stop working.
Here are some things I have observed:

When this happens, the mouse and keyboard are still recognized by the computer. i.e. when I plug and unplug them I can see them show up and disappear from Windows Device Manager. Also, when I view the mouse and keyboard's device status in Device Manager it reports "This device is working properly."
The USB port on the dock seems to be working fine. I know this because when this happens I can unplug the mouse and plug in a different peripheral (e.g. external hard drive) and find that it works fine. But when I replug the mouse, the mouse still does not work.
I know my mouse is fine, because when it stops working I can unplug it from the dock and plug it directly into the laptop's USB port which causes it to work fine (but if I unplug and replug to the dock it does not work).
The laptop's built-in keyboard and touch pad still work fine.
This usually seems to happen sometime after coming out of sleep especially when waking the computer using the power button on the dock (but not always as far as I can tell so far).
Sometimes restarting the computer fixes (temporarily) the issue.
Sometimes unplugging and replugging the dock fixes (temporarily) the issue.

A:When Using WD15 Dock External Mouse and Keyboard Stop Working Occasionally

This is admittedly a rather long shot, but try installing the latest Thunderbolt firmware for your XPS 13?  I know the WD15 is just regular USB-C and that the USB-C controller firmware is updated as part of the regular system BIOS update, but I'm wondering if the Thunderbolt controller might still be in the hardware path somehow and therefore a firmware update there might fix something like this.

Hi community,  I'm expiring strange issues on some of our X380 Yogas when working with a USB-C Dock (Type 40A0). The cursor starts to freeze for a second, and then jumps, sometimes the keyboard types unwanted letters (I don't know the english word for it, but e.g. I would like to type Thinkpad, and out comes Thinkpaaaaaaaaaaad or Thinnnnnnnnnnkpad), and on a connected USB Headset the audio quality is bad. This happens only with USB devices connected over a USB-C Dock, if directly attached to the Yoga its fine. Also the internal Keyboard and Trackpoint are working fine. There are not always all 3 problems the same time. And usually after a clean boot everything is OK, it happens only after undocking, and docking in again.  On some computers having that problem, installing the USB-C Dock Firmware update fixed it. But on some others it does not. Anyway installing this Update is a pain, since it cannot be installed unattended. Maybe any ideas here? I have not contacted Lenovo support yet about this. Regards, DJ

I have a X1 6th Gen. Recently I got two different Thunderbolt 3 docks. Work gave me a Kensington one. I bought a Caldigit one for home. I have them connected via the diagrams below - basically through my monitors as usb Hubs. (nBoth docks have similar problems: 1. Keyboard repeats keys: https://tinyurl.com/TB3Keyboard2. Mouse randomly pauses: https://tinyurl.com/TB3Mouse3. Web cam stuters: https://tinyurl.com/TB3Webcam4. USB Head set crackles5. Sometimes my laptop hard freezes requiring a hard reboot. Yuck. There's even more USB devices (phone, etc) but they're more "optional" than than mouse/keyboard/webcam/headset.  When i connect them directly to the docks, there's no (maybe fewer?) problems.  Has this happened to anyone else? It feels like an X1 problem since this repros with two different monitors and two different docks. A few other coworkers have reported weird issues as well with their X1 and the docks.

I have a user with two LT3053s (2560 x 1600) and his previous T440 + Ultra Dock (I believe) supported the full resolution at 60 Hz (again I believe).  I upgraded him to a T480 and our standard Type-c dock that we deploy limited the screens to 1920x1080 @ 60Hz.  After this and complaints from the user of headaches from the drop in resolution we purchased a TB3 Gen 2 Dock and even after plugging the dock in to the actual TB3 port on the laptop (not the top type-c port) we are having issues with not all of his devices working, namely the kb+m. Any ideas here?  Right now we are running it with the 135W power adapter that it came with, but there is also another power adapter available that did not come with the unit we purchased.

Hi guys, I have a ThinkPad T480 combined with a Pro dock (side). I was hoping to use 3 external monitors (not including the laptop screen). The pro dock only has 2 display ports and the laptop has a HDMI port which i was hoping to all use to get my 3 displays.My setup is 2 VGA external monitors to display port adapters and 1 hdmi monitor to the laptops hdmi port directly. 2 display port monitors display fine, however the HDMI display goes black. If i un dock the laptop, the HDMI monitor works.Can i not output all 3 at the same time, i know the laptops chipset allows 3 monitors.I was thinking of buying a USB C to HDMI adapter for the 3rd monitor, maybe this would resolve it? thanks in advance

Hi all,

Hoping the forums can help me out….

I have a friends laptop (Notepad, 32MB ram, 5GB hd,133mhz processor, 2mb video ram, win 98 o-s) anyway it worked fine when I got it off my mate to load Office 2000 on (she’s not comfortable doing things like that…worries that she’ll break it..)

All is ok..except for the mouse….

If I boot up without the mouse plugged in, the p.c. boots as normal and everything works. I can then plug the mouse in and use it. However if I plug the mouse in and then reboot, the p.c. gets stuck in the start up boot…If I reboot using “restart” with the mouse plugged in, all is ok, but if I shutdown & then switch of it doesn’t work.

It literally gets as far as the part at the start of the boot up where it counts up the base memory and freezes, it doesn’t go onto count the extended memory (ram?) as it does normally.

My only option is to unplug the mouse and reboot without it in.

I’ve spoken with the friend who owns it and she says she’s not had this problem before.

I cannot think how putting office 2000 has had this effect and wonder whether it’s just a coincidence..I have uninstalled Office 2000, and I still have this problem.

Anyway, any thoughts/ideas welcomed. I’m due to give the p.c. back tomorrow so am hoping we can sort this before then!

Thanks in advance.


A:[SOLVED] p.c. won't boot up with the mouse plugged in

Did this problem start only after installing MS Office or did you've the same problem prior to Office's installation?

It seems weird that only in the boot process this is happening and after windows starts you can use the mouse!

Anyways what port does the mouse use USB/PS2 ?

AOTBE, this doesn't happen at all when I have a normal PS2 KB/Mouse plugged in.

However when I replace that with USB KB/Mouse there is a problem. This has been happens whether I use my Logitech USB KB with Logitech Mouse. And the same with Razer KB and Razer Mouse. So I'm presuming this happens with any KB/Mouse plugged in by USB.

1. I'm in Windows. I hit reset, and it freezes at the post.

2. I'm in Windows. I shut down the PC. The next time, I power it up, it goes through a really really long boot to Windows. Then the screen goes blank.

The only way to resolve this is by completely powering off my PC. Meaning I shut it down. Then flip the switch on the PSU to off.

Only when the power to the PSU has been switched off will the PC boot all the way into Windows when turned on and powered up. And even in this case, it takes a pretty long time to boot. IDK if W7 normally should take that long.

(With my other PC using W8, I get absolutely no problems. Restart is amazingly fast. So is booting after being powered off. And there's never a need to shut it off completely from the PSU switch.)

I was wondering if anybody had an idea what's going on. I haven't tried any different configurations to test it out other than 2 different sets of USB KB/Mouse.

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

I own a Thinkpad T480 (20L5: Intel UHD graphics, Core i5 8th gen) and since it supports Thunderbolt 3, I want to attach an external GPU and display for light gaming. I see that Lenovo itself has a "Lenovo Thunderbolt Graphics Dock" but does not offer that as compatible with the Thinkpad series. Nevertheless, as Thunderbolt 3 is a standard, I am wondering if the Graphics Dock works with the T480. Did anybody already try that?

We are currently using Lenovo T480 laptops with ThinkPad Thunderbolt 3 Docks (Model 40AC0135US) in our office and frequently encounter the following issues: ? When a user connects their T480 to the dock, their monitors do not display any video? When a user connects their T480 to their dock, their monitors will display video, but USB peripherals (keyboard, mouse) do not work? When disconnecting from a dock, the charging light on the T480 stays lit and Windows shows the laptop is still connected to power and charging? External displays flicker intermittently When a user experience issues with their dock, the only way to get things working again is to shut down the computer, disable the internal battery in the BIOS, and then plug the T480 into the dock and turn it on. However, the issue eventually returns and we have to repeat the steps again. We have also tried the following steps, but continue to see issues:? Run Lenovo System Update and install all driver, bios, and dock firmware updates? Replaced Thunderbolt cable? Change the Thunderbolt Security Level in bios to No Security and Uninstall Thunderbolt Software Most of our laptops are running Windows 10 1709. Has anyone else experienced these issues and know of a good solution?

Have you tried to use a different USB port?

In the BIOS does the BIOS have control of the Keyboard or does the OS have control?

I was having trouble with my pavilion burning up hard drives so I purchased a new one rather than replacing it with the same one HP always done. I purchased the hard drive from Best Buy and they installed it into my laptop. I then loaded the OS and applications and drivers using the original recovery disks provided by HP. After that I updated windows XP until all the updates were completed.
My problem is that the computer doesn't recognize usb mouses. I tried using my Razer Diamondback and it wouldn't recognize the hardware. After using the driver install disc provided with the mouse it still wouldn't work. I also attempted to download the lastest drivers directly from the website and that wouldn't work. I've had two other people who are much more computer literate than myself look at the computer and they couldn't figure out the problem either. It appears that it is only a problem with mice. I tried another mouse and it didn't work either. Also it recognized other usb 2.0 equipment just not mice. My friend also said that with the current XP installation service pack 2 it should automatically recognize most usb devices even with the driver disks. Any help into what could be causing this problem would be appreciated.

A:Laptop not recognizing mouse plugged into usb port after hd switch

Hi friend....

The most likely to happen in your case is that while repairing your system they reseted CMOS/BIOS or they updated it (it usually resets itself to defaults after update). In BIOS there is an option for usb keyboard and mouse support. Since you have a laptop this option could be by default disabled. Hopefully, getting into BIOS and enabling usb mouse support will do the job! This option is more likely to be found in the "integrated peripherals" section of your BIOS setup. Then exit and save. Usually to access BIOS you have to press DEL during the POST/startup screen. You may have came across the message "Press DEL to enter setup". I cannot know many details since BIOSes have differences between computers especially laptops. Of course go ahead on asking questions if you want me to be more specific on something.
