After connecting the power adapter, the CPU is lowered at a constant 0.39GHz! Thinkpad Yoga 460

Q: After connecting the power adapter, the CPU is lowered at a constant 0.39GHz! Thinkpad Yoga 460

Hello, this has been solved here, but the version of "defect" is indeed the opposite. (sorry my english) As other users solved this problem with - it did not help using more powerful adapter with 90W 4.5A or upgrade BIOS. Power Saver off, no other power saver activated. Many times HW tests from Windows Troubleshooting and Lenovo Vantage - everything OK. I attached here HWiNFO specification. - Lenovo Thinkpad Yoga 460 (Windows 1709, all current drivers updated - no change with update 1803 - same situation) The power adapter (and also i use many others - no change) will immediately reduce the processor frequency to a constant of 0.39GHz and using the bounce between 0 - 15% .Reinstall Windows, HW test and drivers etc. everything is OK. Even no help from Settings - Windows - Options of Power - set min. usage processor 100% - no affects. The problem persists. ..omg... , whats that? Common opening of Explorer, Word, copying etc., and other elementary activities are now a matter of minutes - big loss of performance. Thank for your help

It's worked out well for many of us in the past.

My Yoga S1 has contradictory, intermittent power issues that I'm trying to chase down. Culprits are bad power bric/cord/plug or power socket on mother board or power board that feeds into power button/led on. One day it blacked out and wouldn't restart to hard drive or windows stage. I did get an error code which I can't remember 5100 or 5500 poss?, that seemed to indicate the power board or ribbons to that needed replacement or re-attachment. So fiddled with it and it did fire up in windows all ok. Then ran out of power and died again. power button wouldn't light up. plugging in power unit did light up led as getting charge. Left it overnight and then it miraculously charged up. pushed power button light up twice then nothing. took out power board/detached ribbon, then it fired up to windows, fixed some hd errors and has been restarting without problems. Except now there is no plug showing on battery icon when plugged in. So not recharging but I'm sure the battery is good. And logically, the power brick and plug must be feeding electricity into laptop to get it to recharge enough to start up. So power socket and plug may be suspect with intermittent contact problems. Or the power board somehow is involved in this? I've ordered a new powerboard as easy screw in and cheap. My question about powerboard is does this control ability of plug to charge battery? power brick with new plug is next order from ebay. but the power socket, which see...

Dear all,  I've recently purchased a Thinkpad X1 Yoga 3rd gen 20LES01W00 (i.e., i7, 512GB SSD, 16GB Ram) and though it's a great device there's something that's driving me insane: A constant background eloctrostatic noise. Its a high pitched 'bzzzzzzzzzzzz' and apparently it is emitted from the left part below the keyboard (below the 'caps' key) - when moving my ear close to this location I can hear a permanently 'wipp wipp wipp' sound in addition to the constant 'bzzzzzzzzz' eloctrostatic hum. These noises occur as soon as I start the laptop with any application (or without any, mind you) and is also existent when I use the laptop in any other mode, e.g., tablet mode. I have installed the newest BIOS with Lenovo Vantage. So far, neither restarting the notebook nor setting back Win10 Pro 64bit (the 'light and easy' setback) does help.  What should I do? And what is that noise? Cheers-Felix

I have X1 yoga laptop that won't boot. I tried booting from a USB, but that did not work. Hardware diagnostics returned no problems. At this point, I am trying to salvage my data from the SSD. I want to remove SSD from the laptop and connect it through some cable/adapter to another computer to copy my files. I see tons of options, but I am not sure which one would work for my SSD. The majority of SSD M2 to USB converters support B or B+M key, and then there is something about NVMe or SATA interface... I am very confused and know close to nothing about SSD types, etc. How can I get to my data?

We have standardized our deployments to ThinkPad X1 Yogas, and in many case including this one, they are the second generation model. Because of the performance, we use the Thunderbolt 3 Dock, purchased directly through Lenovo. This setup is not unfamilar to use as we have deployed over 40 workstations in the same configuration. This morning, our team received a call stating that an end-users monitors weren't working. Upon reviewing, we found that the dock wasn't being recognized by the laptop, although the connection was there because it was charging the laptop. We went through the normal "rinse and repeat" steps of ensuring that the thunderbolt cable was connected to the correct ports on both the dock and the laptop, removing the connection, removing the power, rebooting the computer, reintroducing the dock, etc., but to no avail. We remove the dock from known devices hoping that it would spark it to recognize a new device, but it didn't. We removed the Thunderbolt Software completely, reinstalling it, and then reconnecting the device, and still, nothing. Our devices are set to automatically install critical and security updates both through Lenovo Vantage and Windows Updates, but, the only change made between the time it was working and the time it stopped working wasn't relative to the dock. To be sure, we rolled back the updates, then rolled back farther, but it still didn't resolve the issue. We then followed through with installing all Windows and Lenovo updates: ... Read more

Hi all, I have a Yoga 260 and two external monitors.  It does not seem to matter how I connect them, USB, HDMI, whatever the thing with a square on one end and USB on the other, directly or through a splicer I can not get the Yoga to recognize the third screen individually (yoga has one monitor, plus 2 external monitors = 3). I go to display settings but it just will not recognize the third monitor at all unless I use HDMI out of the laptop in to a splicer then 2 HDMIs out and in that case I only get duplicates on the two external screens. Any suggestions about the best way to set up... as in "it worked for me when I connected USB to one monitor, then daisy chained that to a second one" or "it worked for me when I HDMI to one screen and USB to a second" etc... Thank you

I am thinking of buying an X1 Yoga, but am a bit concerned about the lack of ethernet port. I am looking for feedback on the OneLink+ to RJ45 adapter - Lenovo part #4X90K06975. This is the adapter with just the ethernet port - no other ports. I have found some feedback on the docking station, and the adapter with more ports.., but I am interested in the ethernet-only adapter. Does it work well? I've read about a variety of issues with the other adapter and the docking station. one thing that concerns me a bit about the adapter is that the OneLink "plug" looks like it sticks out a lot from the side of the laptop - is it the kind of thing that can easily get dislodged, or broken.., or worse yet.., damage the port in the laptop? This laptop will occasionally be used in a bumpy environment. I see that i also have the option of a USB-Ethernet adapter, but I would rather leave my USB ports free for other devices - connectig to instruments is one of the main jobs for this laptop. Additionally, I assume that the USB-ethernet adapter will need a driver, and i am worried about driver conflicts with the drivers for the instruments. Presumably, the OneLink to RJ45 adapter does not need a driver - is that corect? Thanks for any help

Hi,My Y260 is having a weird trouble which I believe is hardware/motherboard related : whenever I plug the power supply, the CPU steps down to 0.38GHz... This is 1/6th of the full 2.3GHz the i5-6200U can provide, and the CPU is stuck at 16% use, which is 1/6th of 100%.If I unplug the AC adapter then the machine shuts down as if it had no battery. If I start it without an AC adapter then the CPU uses the full 2.3GHz and everything is fine, until I plug it in !I already tried disabling Intel Speedstep or any power saving stuff onto the BIOS, and I ran every Lenovo hardware tests and everything seems OK. Do someone have any idea about what I could try ?If none, I will have to call Lenovo (46 days of warranty left !) but I would prefer not I need my Thinkpad for my job. Thanks,Boris (from France so excuse my english)

I've had my yoga for almost two years now and recently I've been having two issues: 1. The WiFi adapter will sometimes go out and it won't even show up on the device manager. The only "fix" I've found so far is to shut down and turn the computer back on (usually at least a couple of times) until the adapter starts showing up again. I've gone to the bios to check to see if it's showing up when I run the motherboard test and sometimes the PCI slot that it occupies doesn't even show up. I've been having to use a small USB WiFi adapter when the onboard adapter feels like being particularly uncooperative on certain days. 2. At random times (every few hours or so) when the laptop is just sitting on my desk, I will get an auto rotate notification and the screen will change its orientation, go into tablet mode, and disable the mouse and keyboard. Usually the screen will go back to normal after a few seconds, but the keyboard and mouse will still be disabled and the only way to get them both activated again (as far as I know) is to shut down the laptop and then turn it back on. My guess is that these two problems might be related. The reason why I think so is because I had similar issues a year ago with the WiFi adapter frequently not showing up on the device manager. I had the laptop sent in and it turned out to be an issue with the motherboard, which had to be replaced. So my guess is that there's something wrong with the motherboard again, which is affecting both the... Read more

Hello I own a thinkpad S1 yoga laptop (core i3 processor and 4 GB RAM). It suddenly stopped charging using 45W adapter (20V, 2.5 A). However, it is charging fine using a 90W adapter (20V, 4.5 A) which I got with my previous Lenovo laptop Any recent windows or system updates caused this? Is there any solution other than using a 90W adapter which I am scared to use as it may charge 47W battery too rapidly casuing a quick death of battery or explosion in the worst case. Please help

Hi Chaitanya,Welcome to Lenovo Community! And happy to have you here.As I understand that you have query regarding your 45W AC Adapter is not charging your ThinkPad S1 Yoga
I believe the AC Adapter has gone bad as you have mentioned that its charging fine with 90W Adapter 
I don't think so it is caused due to software or Windows updates. You can also check whether its getting charged in shutdown mode or not to confirm. 
 
I hope the above information helped you.

Hi all, I've already done a little research into my issue, but I just wanted to ask on here for some direct advice/sanity check. As the title suggests, I was trying to network boot some Yoga laptops using a ThinPad USB 3.0 network adapter (model RTL8153) but have been running into a problem where the adapter is seemingly not detected.  In the BIOS of each laptop it lists "ASIX AX88772A/B", which I gather is the supported chipset for USB network booting these laptops, whereas the RTL8153 is Realtek. When I try to boot, I get this: Enumerating for ASIX USB DONGLE ...
No ASIX USB Dongle found.
PXE-M0F Exiting Intel PXE ROM.
Reboot and Select Proper Boot Device. Now, from my admittedly limited research, it appears that I simply need a USB network adapter with the aforementioned ASIX chipset. Is this true or is there a way to get the RTL8153 working?  Many thanks in advance! (PS Apologies if this is better suited for a more enterprise-centric area of the community!

Hello! Recently I am unable to recharge my X1 with the included Lenovo 65W USB C Charger.  When I plug it in, the orange light blinks (1 second on, 1 off), and the windows battery status icon on the system tray flicks on and off between "plugged-in (charging)" and "not charging".  It seems that when I plug it in, windows is trying to mount something like a USB drive, as the icon to unmount a USB C device flicks on and off.  Furthermore, the task bar flickers as it goes on and off thinking that it is trying to mount and unmount a USB device. I've plugged in a few different USB C chargers I have "for my phone, for a battery pack, from a MacBook, etc...", and they work on my X1 no problem. I have 2 Lenovo 65W USB C chargers, and I've tried both of them with the same result.  I'm pretty sure the chargers are ok, as they will charge other devices (like my phone, a battary pack, and a MacBook).  Just, when I plug them into my X1, I get problems. Not sure if this is due to a recent Lenovo Vantage update, or Windows 10 Update.  I recently did the 2018-12 Windows 10 update.  However, even if I turn the computer off the Lenovo charger blinks the orange charge light, and will not charge the X1. Any help is appreciated. Thanks!

The Yoga 3 Pro power adapter looks like a normal USB brick, and the cord looks like USB, except with a kink in the connector at the Yoga 3 Pro end. Can I charge my phone or tablet with it?

A:What's with the Yoga 3 Pro power adapter - it's a ...

Yes the Yoga 3 Pro power adapter is a USB charger too!
 

How does it work?

The special "fool proof" charging cord has two extra pins on the AC adapter end and two extra pins on the Yoga 3 Pro end. The extra pins only make a connection when the fool proof cord is plugged in to the Lenovo charger and the Yoga 3 Pro. When a regular USB cord is plugged into either the charger or the Yoga 3 Pro, it makes a regular USB connection.
 

Can I charge the Yoga 3 Pro with any USB charger?

No. The Yoga 3 Pro requires 2A at 20V, which is what the provided 40W Lenovo AC adapter supplies.
 

Can I charge a USB device with the Yoga 3 Pro AC adapter?

Absolutely. In addition to 2A at 20, the Yoga 3 Pro AC adapter supplies 2A at 5.2V (10.4W), enough to charge a phone or tablet. Works for iPad.
 

Where can I buy spare AC adapters and cords?

AC adapters with cords are sold in the accessories section of the Lenovo store.
 

Where do I find the part numbers for the AC adapter and cord?

Look for AC Adapters In the PDF Yoga 3 Pro Hardware Maintenance Manual.
 

What are the USB specs of the Yoga 3 charging port?

It's a USB 2.0 port. It provides enough power to charge an iPhone, but not enough to charge an iPad. If you want to charge an iPad, try the USB 3.0 port on the right of the Yoga 3 Pro.

We have three Think Pad Yoga X1 (402KZLJ) 2 of which are experiencing the same crash.  See below image. This crash only seems to occur when we unplug from battery - take machine to meeting - then within 10 minutes it usually crashes as seen in the below image.  Machine reboots.  Windows identifies the crash and notes a dump file.  Machine then runs fine for the remaining duration of the meeting. The user does 'docks' (into a Display Link USB 3.0 hub) the machine.  At first we thought this was the issue.  So we repeated our tests with just plugging in battery power.  The crash occured again.  Granted the Display Link driver is still present - it now seems more releated to 'battery'. This machine does not contain any Lenovo 'Power Manager'.  So if this needed... we don't have it.  At this point we are trusting windows power management.  I did read Lenovo Power Manager and Lenovo can conflict. Each time the machine crashes it generates an dump file.  The dump file points to this file as being the issue 'dxgmms2.sys'.  Looking this up it is GPU.  This is fully patched.  We did an uninstall and reinstall of the GPU driver - twice. We updated all the drivers (BIOS, firmware, wireless, etc.) for it from Lenovo and Display Link.  This is our second fresh install of Windows 10 Enterprise- both experienced the crash. Has anyone else seen this?  Any othe...

Hello everyone,  Trying to purchase an extra charger for the Lenovo Thinkpad T470 (which was bought in the US) and would love to know which one I can order locally, from Lenovo India.  These are the chargers are available and I can either buy an USB type C charger or the slimport charger, right?  https://www.lenovo.com/in/en/accessories-and-monitors/chargers-and-batteries/chargers/Lenovo-45W-AC-...https://www.lenovo.com/in/en/accessories-and-monitors/chargers-and-batteries/chargers/Lenovo-65W-AC-...https://www.lenovo.com/in/en/accessories-and-monitors/chargers-and-batteries/chargers/PWR-ADP-BO-USB... This is the one that came with the laptop (USB type C):   Would be great if you could please suggest what would be a good buy for this laptop or if it's better to buy a charger from Lenovo USA.  Thank you for  your time.

A:Recommended power adapter/charger for Lenovo Thinkpad T470

I would buy the USB-C, thinking if or when I replace the laptop, the USB-C charger is more likely to work as a spare.  As far as wattage, the 45W will be lighter, but 65W may charge some devices faster and is more likely to be compatible with any replacement.  (I am not suggesting that you are going to replace the laptop soon, but things happen and situations change.)

Hello, I want to get a spare adapter for my Yoga 910 and I want to make sure I get one that will not damage my computer. I really don't know anything about these so please bear with my ignorance. There are many different ones on Amazon that claim to be for a Yoga 910 but since some of them don't even have a USB-C end, I'm hesitant to trust that all of them work. In particular, I'm interested in this one because it has a longer cord. http://tinyurl.com/y9e7dzuk But I note that it's 65W instead of 45W. Is this a problem? Thanks in advance. James
