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.)

I ran a speed test on my new T480's USB-C port on an external SSD. I am using a Sabernet SSD external enclosure with a USB-C adapter. Inside is a m.2 SSD (not NVMe). I also tested the same SSD with a USB 3.1 adapter and the speeds are MUCH faster on the USB 3.1 than the USB-C port. I can post screenshots of CrystalDisk if needed. Any advise?

A:New T480 USB-C port SSD speed slow

Out of curiosity, when you say: "adapter," what do you mean? It is a whole new cable with the A and C heads? Or is it just a small block where you plug the existing USB-C cable into? The reason why I ask? Is it possible the USB-C cable is actually USB 2.0 spec (like a USB-C "charging cable"). Of course, if you are using the same USB-C cable in both instances, then I do not know what to do. There are two USB-C ports on your T480, maybe try plugging it into the other one?

There have been several reports of the Thunderbolt 3 port on the XPS 15 9550 (and 13 9350) being configured to a PCI 2x port instead of the more usual PCI 4X port. Users have been reporting speeds of up to 16 Gbps, only half of the advertised speed (40 Gbps) which should be 32 Gbps (with overheads) for data.

https://egpu.io/forums/pc-setup/xps-15-9550-not-able-to-reach-40gbps-over-tb3/
The result is significantly TB reduced performance to comparable machines, especially when using an external GPU set up.
If this is not hardwarematically configured as such, it may be possible this could be fixed with a firmware update. Will this be coming?

Hi,
I myself own an XPS 15 9550 and noticed that I was not getting the full Thunderbolt 3 speedover it's Thunderbolt 3 port. I expected speeds around 2700MB/s, because of the overhead withthe theoretical gross speed of 3870MB/s, but I only ever got 1400MB/s out of it.
I did some digging and found out that none of the XPS notebooks with Thunderbolt 3 are evenable to achieve the full TB3 speeds, because they are only connected with two PCI Express lanes (x2.3).You can read more about this on the following links:Dell Subreddit PostChipset Digging on Forum

Thunderbolt 3 and the promised speeds were the MAIN REASON I even bought this notebook.I feel very cheated here.

My t480 no longer charges via thunderbolt dock. Sometimes it wontw boot if anything is plugged into the thinderbolt port either (black screen after Lenovo uefi splash screen) When plugging my power adapter into the port, it will enter pluged in modern but report not charging. It will maintain charge. When plugging a docking station, attached perepherper function normally, but again, not charging. This behavior started recently.  Additionally I noticed that in device manager the UCSI USB connector manager sometimes will error out with an error 43. But this is sporadic and may be unrelated. Device manger view appears to repeatedly refresh, but have not been able to discover the conflict. I refreshed the os (win10) and it worked correctly for a bit, but then started doing the same thing again. Is this an error induced by a recent Lenovo or Microsoft update? Hardware problem?  Software?

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.

I am using a T480 with the TB3 dock and 2 external monitors.My problem is my screens go black for a couple of seconds every x amount of time. I've updatad all drivers found under the Display and Video graphics section Drivers T480I remember when updating to Intel Thunderbolt Software for Windows 10 (64-bit) - ThinkPad T480, T480s, X1 Carbon Gen 6 - 1.41.565.0I received the following screen:(I did get 2 Thunderbolt SW apps in my start menu and uninstalled the one which was visible via add/remove programs) These updates did not resolve my monitor issue.I later on noticed there is a new TB3 Dock FWWhen I wanted to make the update I got the message the TB SW had to be above 17.4.77.400.

I have a new T480 and Lenovo Thunderbolt 3 dock. I find that often when I close--but in no way shut down--the computer for the night, when I restart in the morning, it completely restarts, so I lose open tabs, unsaved work, etc. I can understand enough of the system event log to determine that the computer always goes to sleep when I close it, then, per the power plan, hibernates three hours later--or at least tries to. The first sign of trouble in the logs comes at the time of hibernation. For example, at 2:37:25 this morning there is the routine Information event, "The system is entering sleep. Sleep Reason: Hibernate from Sleep - Fixed Timeout." This is followed immediately by the warning, "6105 - deauth after EAPOL key exchange sequence". Over the next 5 minutes come two more warnings and eight errors. Then nothing until I start the machine in the morning. One of the first events on restart is the information message, "The last shutdown's success status was false. The last boot's success status was true." It appears to me that this only happens if the computer is plugged into the Thunderbolt 3 dock overnight. To the dock are connected a (gigabit) ethernet cable, a displayport monitor, a mouse, a keyboard, and a pair of headphones. Here is a fuller dump of the error log at the last time it was hibernating, or trying to: Level Date and Time Source Event ID Task CategoryError 7/30/2018 2:41:33 AM Microsoft-Windows-DistributedCOM 10010 None The server {3EB...

Hi All,Since a few days I am using T480 with Kubuntu 18.04.When I use the laptop for web browsing and text edition (light use which should not consume too much resources), the CPU's temperature is always around 50 deg C, with the fan speed of around 3000 RPM (the average CPU usage is 6%). The MX150 GPU is disabled with NVIDIA X Server Settings. If the GPU is on, the temperature and fans speed is more or less the same. Has anyone experienced similar CPU's temperatures regardless if it is windows or linux? Are such temperatures normal? The housing is pretty warm all the time.The ambient temperature is around 24 deg C. Best regards,Lendzian

I'm thinking of getting a P70, I see it has 4 USB 3 ports and 2 Thunderbolt 3 ports.  My questions are: 1: Is each of the USB 3 ports connected to their own controller so that each port is capable of it's maximum bandwidth?  Or are all four ports connected to the same controller so that the data bandwidth is divided among the four ports? 2: Similar Thunderbolt 3 port question.  Is each of the two Thunderbolt 3 ports connected to it's own controller?  Or is the bandwidth shared between the two ports? I'm planning on using the USB 3 ports (maybe Thunderbolt 3 also) with a high end, high data rate USB 3 camera that, according to the specs, can use up 95% of the USB 3 bandwidth.  If I were to use two cameras at the same time, it would not work if all four ports are connected to the same controller/bus and sharing the bandwidth.  I have read that laptops usually share all USB ports on the same controller.  I'm hopeing it will be different with the P70, being a "professional" workstation class product. Thanks

I'm using the thunderbolt port for a single connection to a Dell usb-c dock (power in, KVM out, speakers, network, etc.).  The 720 charges real slow and the battery status message (in Lenovo Settings app) states that the "AC adapter cannot provide enough power for normal operation of your computer".  The Dell usb-c docks are powered with a 180w power supply that provides 60w of power to the computer, which is more than the 45w power supply that comes with the 720.  I have tried 3 different Dell docks, including a Dell thunderbolt 3 dock with a 240w power supply. I have to believe this is an issue with the Thunderbolt 3 driver on the 720 or something BIOS related.  BTW, the 720 has Windows 10 pro loaded (updated from the home version loaded by default) and Bitlocker enabled.  Don't think these changes have anything to do with the issue. I purchased Lenovo's thinkpad usb-c dock (which states that it's universal) and hope it charges the 720.

Downloaded the newest Thunderbolt driver this morning. It MAYBE fixed the occasional outage problem that many are having with Thunderbolt/USB-C port adapters - jury is still out on that.
Here is what it DID NOT FIX: The fan speed. No matter what I plug in to that port, the fan revs up and stays up. 
I disconnect all USB-C adapters and revert to my USB 3.0 equivalents and everything works fine. I have a 3.0 LAN/Gigabit port and a Plugable 3.0 to HDMI adapter that are working great with no fan revving.
The minute I use my USB-C versions, that fan gets spinning. Why? Watching my Task Manager, I can see 1-4% CPU, 20% Memory, 1-7% disk. There is NO REASON for that fan to be running.
Until Dell and Intel get that Thunderbolt port dialed in, I'm staying on good ol' USB 3.0. At one level, that is frustrating as I bought the XPS 15 partly because of the promise of the "One port to rule them all."

A:Dell XPS 15 9550 Thunderbolt and Fan Speed

I agree 100%. Bottom line is that ThunderBolt 3, at least in the XPS 15 9550 implementation, is not ready for prime time.
Right now I am running with my XPS 15 closed using an external monitor connected to the integrated HDMI port, a USB 3 adapter into which I have plugged my gigabit ethernet, my usb keyboard, and my integrated monitor webcam. I also have my wireless mouse dongle connected to one of the integrated laptop usb ports and have my power adapter connected. Fan is completely silent and everything works perfectly. I should be able to connect all of that thru the TB15 dock using the single Thunderbolt 3 connection to the XPS 15 9550 with exactly the same results. Unfortunately with the current state of drivers I cannot.
I bought my TB15 dock directly from Dell. Their can't be that many of us. You would think Dell would make the effort to make sure that all of us that did would be communicated to and taken care of...apparently not.

Thinkpad X1 Extreme Platform Specifications:https://psref.lenovo.com/syspool/Sys/PDF/ThinkPad/ThinkPad%20X1%20Extreme/ThinkPad_X1_Extreme_Platfo... On the above link, Lenove states this device only supports [email protected] on DP output of Thunderbolt 3 port, which indicates each Thunderbolt 3 port of this device supports only 2 PCI-E lanes. But on the other hand, there are some articles claims that X1 Extreme supports 4 PCI-E lanes on each Thunderbolt 3 port. Which is true?

Does anyone know how many PCIexpresslanes are allocated to the thunderbolt 3 port on the Yoga 730 15".  I have gotten in touch with lenovo technical support, but they had no idea. I did see where the 720 is thought to have 2 lanes, but I am not sure if that is the same on the 730. Thanks for any info!

Hi,I am trying to hook 2 Dell U2417H monitors via the W541 Thunderbolt/mDP port. I am chaining the 2nd monitor from the 1st using its DP output port. The MST is only enabled on the first monitor as instructed. My laptop has integrated NVIDIA K1100M video card which is capable of daisy chaining.https://www.nvidia.com/content/PDF/line_card/6660-nv-prographicssolutions-linecard-july13-final-lr.p... I cannot extend to the 2nd monitor as it does not detect any signal. I know that my 2nd monitor do work. There seem to be no option to turn on/off MST from my laptop. I don't see where the problem can be. Can someone help? Thanks

Would like to connect my HP27Q (5K, dual display port) monitor to the new Apple products using Thunderbolt 3. There are several Thunderbolt 3 hubs that provide dual display ports but they only work with Windows. I do know that I can go with an Apple machine that provides dual Thunderbolt 2 ports such as recent iMacs and Mac Pros but that isn't a desirable solution. Any ideas?
