X1 Yoga 3rd gen caught in heavy throttling state while connected to power

Q: X1 Yoga 3rd gen caught in heavy throttling state while connected to power

This may be a one off, but I thought I'd report it just in case anyone else comes across it. Scenario - Disabled wifi, logged off, closed laptop- Got to work, connected X1Y3 to TB3 dock (connected to ethernet, iPhone connected to TB3 dock)- Pressed key on attached USB keyboard to wake the laptop, logged in From that point on the fan would basically not come on, the CPU refused to go above 2GHz, and when launching a bunch of 'apps' the CPU would throttle down to as low as 0.5GHz, while CPU utilization wouldn't go above ~25%. That way the system kept the CPU temperatures below 65C seemingly without using the fan. I wasn't able to see any settings in Windows power settings or in the Vantage app where I could adjust this behavior. Needless to say performance was terrible. A reboot fixed this. It kind of looks like the X1Y3 got stuck in the "on battery power" plan, not sure how this could have happened. Any suggestions on where to find the settings corresponding to this incredibly conservative power plan? Or is there a chance this was not a power plan but rather a case of 'the fan didn't work'? Preliminary theory: maybe the fact that the iPhone was on the TB3 dock plays a role here, since charging the iPhone draws significant power. I wonder if the X1Y3 can be tricked into thinking that it's on battery power when the TB3 dock can't deliver sufficient power on wake. This might explain getting stuck in the 'battery mode' if subsequently the X1Y3 firmware doesn't adapt the power plan until a user connects or disconnects power.

When using my P51 on battery power it seems to throttle heavily regardless of the bios options, or the Windows option to allow for best performance.  Running something like the benchmark utility in CPU-Z the processor will start at a higher clockrate and then fall to 800Mhz quickly.  The system acts as expected on battery, the clockspeed stays high and is very quick. Can anything be done to allow for something inbetween on the battery?  I'd rather have a little less battery life than sometimes getting a bit of lag running at 800Mhz. Thanks

Hi, My CPU has been throttling down to 400 MHz when on battery. This does not necessarily happen on low battery - it sometimes happens when I have over 50% battery life left (albeit the removable battery is low), and sometimes when i have less than 25% battery life left. My temperatures appear to be good (according to Core Temp), usually around 40-50C. Has anyone encountered this problem before? All of my drivers are up to date according to Lenovo companion, and I have placed power settings in windows to High Performance, and changed the Intel Speedstep settings in the BIOS to max performance as well.

Hi everyone, Long-time W520 owner here. With the FHD display, and the 32 GB RAM, 500GB SSD & 2TB HD I've upgraded it with, after five years it's still a fine machine in many respects. Lenovo makes great workstations, kudos to the team behind them. However I face a pretty annoying problem: under load and on AC power, when using all cores it quickly and regularly drops down to the slowest state, which is about 800Mhz, sticking with that for some minutes, coming back to 2.2 Ghz, sticking with that for less time, and repeating that cycle.  I'm not expecting a machine that never throttles, but I'm sure it used to be a lot better. I've tried blowing out the dust with a Giottos Rocket Air Blower, but it makes no difference. Perhaps the CPU thermal compound has reached its EOL, and an application of new thermal paste would restore its former glory. The thing is, is it worth paying someone to tear it down and apply that paste? Or is it doable for me to do it myself? I'm not at all an expert, and I don't want to inadvertently wreck my only computer. Quite apart from the cost, there is the issue where due to its age I wouldn't be surprised if random things start to break. And it is aging. The screen isn't as bright as it once was, for example, which is easy to tell because I regularly calibrate the display using a high quality calibrator. Thanks in advance for any advice!

A:Heavy W520 throttling worth fixing?

Welcome to the forum!
 
That's a nice specc'ed W520 you have! In my opinion it has surely quite some power for the years to come, (although that may depend entirely on your computer needs).
 
Replacing the thermal compound is not difficult, all you need is a screwdriver, a small plastic pick and good thermal paste brand (like Artic Silver 5, Artic Cooling MX-2, Noctua NT-H1, Thermal Grizzly  Kryonaut, to name a few).
 
You can download the hardware maintenance manual and check chapter 9, step 1150 to see what needs to be done, then you can decide if you feel confident to do it yourself or ask somebody to do it: click me!

I have tried every possible solution to find out what the problem here is and am unable to find any way to fix it. I have maxed out all power settings in windows power manager (including advanced settings. I have maxed out everything to do with battery power in the bios settings. I have used throttlestop and disabled bd prochshot. Used nvidia inspector and evga to try and overclock them over. The GPU is specifically locked in at 457.3mHz on the battery, While plugged in, I can get the gpu to around 750mHz or about 830mHz if im overclocking. Does anyone else have this issue and know if this is a windows, driver, or bios problem. I am running my laptop off a 9 cell battery and I am certain that it would provide enough power to all the components. It is my belief that each lithium cell can safely discharge about 5 amps each which means that with a 3s3p setup, you will get about 10.8 volts at about 15 amps. With this configuration and using ohms law, I have found that the battery of this laptop is capable of providing about 162 watts of power to all the components. This is around the same power of the charger (170 watts) which is enough to power the computer at full speed and still have enough to charge the battery at the same time. I would Really appreciate a response and replies from people with the same problem.

Hi all, i just got a brand new yoga 910 from the lenovo store and was running it through its paces.First off, I'm not noticing any fan noise issues at idle - mid load. So that's a relieve. However, I've noticed some slow downs during sustained load (CPU @ 80-100%).  The CPU reaches around 91 degrees celcius after a while and then throttles the clock speed back to 400 mhz for a few (5-10) seconds until the processor package has cooled down enough.It'll then speed back up to 3.2 - 3.4 ghz until it reaches 91c again.  I'm pretty sure i'm encountering thermal throttling due to a cooling issue. However, I find it strange that the CPU doesn't power down to a sustainable clock speed.  Has anybody else encountered this?  When I limit the CPU to a maximum processor state of 99%, it doesn't boost and stick to ~2.8 ghzI've got the latest bios version installed and the issue occurs both in balanced and high perf mode. Haven't tried quiet yet. CPU: i7-7500u Temp Monitoring: Open Hardware MonitorClock Speed Monitoring: CPU-Z  

A:Yoga 910 cpu throttling to 400 mhz

quite mode seems to be much less agressive when it comes to boosting clock speeds. It keeps the CPU just below 3 ghz under sustained 100% load.I guess the other modes (balanced and high perf) will only work if your cpu is up to the task (be lucky, get a good cpu)

I have a problem with the performance of my Lenovo X1 Yoga 3rd generation. The CPU performance is throttled when core temperature reaches 85C. The i7-8550u processor is not supposed to throttle until it reaches 100C (and this is also what other X1Y3 owners seem to report), but for some reason my specific laptop is configured differently. In addition, the fan fails to spin up during heavy load, probably because it is temperature controlled. This causes additional throttling. The result is that my laptop performs poorly under heavy CPU load. I have attached a screenshot from Throttlestop, which displays the temperature the CPU is configured to throttle at. I have tried updating to the latest firmware and I have updated all drivers, but the problem persists. Can I do anything to resolve this issue?

I have recently bought a Yoga 520 with an Intel Core i5-8250U and Geforce 940MX and so far I have been impressed with it except for one thing : Under a short, full load, the CPU throttles really, really bad. It would start strong and around 2.6-3.4Ghz but then around 2-3 minutes later it would stay at 1.6Ghz. Once it hits 1.6Ghz, it won't clock any higher even if the temperature/load has been back to normal unless i reboot it. I have tried to update the BIOS and even relpacing the thermal paste with a high-performance one and it still throttles. My question is, is this normal? I see no reason for throttling the CPU since the thermal headroom is still plenty when its under load (around 66 degrees celcius). Or perhaps does Lenovo implemented a specific power management? such as setting the CPU cTDP-down to 10W-12W instead of the normal 15W? My reasoning for this is that the HWmonitor reading for the CPU power never really exceeds 11 Watts once it's under full load.

A:Yoga 720 15 what throttling CPU level is normal?

Hello.I have done a bit of research about your laptop, and here are my sayings:Does your laptop feel hot to the touch when you are using intensive application, or it's just comfortably warm, or a bit cool?If it is just comfortably warm, or a bit cool or so, then the probable reason why your CPU and GPU drops frequency is to save battery life, and so that your laptop won't heat too much.Also this is part of the Nvidia Optimus Technology where it switches graphics from integrated (Intel) to dedicated (Nvidia) and vice versa. It would only use the dedicated GPU once you are using an intensive application like gaming or video editing software.The fan of the Lenovo Yoga 720 is actually a bit quiet, even when running those intensive apps.Try plugging in your battery with an AC Adapter and see if the CPU and GPU remain at 100% consistently.I have this with my Lenovo Ideapad 320 and whenever I unplug the battery, after some time both the CPU and GPU starts to reduce its frequency and performance, and it made my game lag. Plugging it back actually solved the issue.

Is it possible to raise the cTDP of the Yoga 370?Currently my i3 throttles at a low 60 degrees celsius because of a 10W cTDP. I am sure the cooling system can take a higher temperature of 70 degrees safely. I have used Throttlestop to confirm that the limit is due to cTDP and not temperature (i processors can run way hotter safely). When throttling at 10W my i3 (without Turbo Boost) cannot maintain clock speeds. I'm sure this is worse for those with i5 and above so please increase the cTDP. If 15W is too high maybe 12-13W instead of the current 10W will help a lot. My readings were taken when plugged in and on all high performance settings enabled.This is important as with the 10W cTDP limit active, the CPU runs between 1.4-1.6ghz under load which is a drastic drop and not necessary since temperature is only 60 degrees celsius.

My Lenovo 730 15 has the overheating/throttling issue while gaming (see the attached screenshot). It is clearly related to the high CPU temperature up to 100C (pink) during the GPU load (dark green) while the temperature in the room is 25C. Since both CPU and GPU use the same heat pipes, the increase in GPU temperatue (blue) leads to the increase in CPU temperature (pink). The power plan has stock settings (turbo boost on and no undervolting) but looking at the CPU frequency (salad green) it's almost not turbo boosting. The base frequency of i7-8550u is 1.8 Ghz and it stays below it during gaming. My question is why putting GTX 1050 in the chassis that cannot handle its thermal load? I have to admit that the fans aren't too loud (Intellegent Cooling in Lenovo Vantage is on) so it could be one of the reasons. I'm going to replace it with another unit and see if the problem persists. Could anyone reply if you have similar issues?

I'm working on deploying new Windows 7 pro x86 computers and I'm trying to get windows to throttle down the CPU when it can, but it isn't always working correctly. The settings for the power scheme that I want are basically highest performance on everything except the hard drive should turn off after 5 minutes of inactivity and the display should turn off after 15 minutes. Instead of reducing the CPU multiplier and parking 2 cores, it will run at 126% (the i7's speed boost thing) with all cores active.

More system info:
Processor: Intel i7 L620
OS: Windows 7 Pro 32-bit
Manufacturer: Coban
Model: M7
It might be something with the hardware since the computers are specialized units, but Coban isn't any help with this problem.

If I create a new profile with the desired settings, the CPU will be throttled usually until I restart the system. sometimes it works longer, but not much more than a few restarts. I have also tried exporting and importing a power plan between different computers and on the same computer and modifying the stock "power saver" plan, all with the same iffy results. The stock power saver plan always throttles down the CPU but only if it's in its default state.

I've seen a few other people with the same problem, but no progress towards a cause or solution. Any ideas?

Hi everyone, I just got a Thinkpad x270 and I'm having an issue where the processor gets throttled to 60c / 2GHz when the lid is closed on battery power.  I posted about it in detail on the Linux Mint forums here.  I originally thought this was a Linux kernel / driver issue, but it turns out this happens on Windows too, no matter whether I set every setting in the BIOS and OS power management to max performance, power save, balanced, etc.  I can get around this by closing the lid on A/C power and then unplugging, or just running the  laptop on A/C while the lid is closed.  If there is some kind of inherent danger in running the processor over 60c with the lid closed, I would expect it to thermal throttle at that temperature regardless of whether or not it was plugged in when the lid was closed.  I can also boot up the laptop with the lid closed and bypass the throttling limitation. It seems like either:- the temperature should always be throttled to 60c when the lid is closed for some reason, and it's not being enforced in all scenarios even though it should be, or...- it's a bug and the CPU shouldn't be throttled at such a low temperature at all. Either way, it seems like there is a firmware issue that needs to be fixed.  Can anyone from Lenovo shed some light on this issue?  Is it by accident or by design?

It's as if it's setting the CPU speed on how much power is coming in to the laptop (as the Power Companion is too weak to charge it).This reminds me of the old issue of the CPU multiplier locking when removing the power connector, which now seems to force the CPU to drop to x9.0 multiplier before climbing back up slowly (so it's not instant, but good enough).Does anybody else experience these issues?

It looks like this has been fixed in the latest BIOS.

System has power at the supply entry (blue light ring) and power at the front (blue power light). When the power on button is pressed the control panel buttons light up, the fan runs and the DVD-RW makes a noise then the system goes dead. Approximately 3 to 4 seconds later, the same thing happens all over again. The system cycles through this infinately until the power supply is disconnected and the battery is removed. No post, no hard drive read... nothing, just this infinate power loop. Can you tell me what might be causing this. I have no idea what version of Windows is on this PC. Thank... Charles

I have a X1 Yoga 3rd Gen equipped with the Fibocom L850-GL LTE modem, using a Verizon LTE sim. I ran into this issue whenever I'm using the LTE connection at high speed, Windows 10 has a high chance of crashing (BSOD). This can be easily reproduced by running a speed test on speedtest.net. I'm in an area with good LTE signal, and my speed on the Verizon sim can reach around 200 mbps. When running the speed test, whenever it goes past around 130mbps, it has a pretty high chance of crashing. It's almost as if the module cannot handle that speed (maybe heat/power related). I'm on a clean installation of Windows 10 1809 with the latest Lenovo drivers (including the Fibocom modem) installed. Anyone else is having this issue?

Hi guys, I'm new here and this is my first post. I have an Optiplex 745 running Windows 7 Professional. Normally in the advanced setting section of the power plan option I have the option to change the power state, however all of a sudden these options have just totally disappeared. Any help is appreciated.

Thanks in advance.

What Power plan are you using ?

Balanced, Power Saver or High Performance ?

Also, run a System File Check

SFC /SCANNOW Command - System File Checker

Use option 2

I just had my W520 power adaptor cable literally burst into flame. I don't kow whether I'm more shocked by the fire or the customer support I have received thereafter. Technical support hung up on me after stating that the item has been out of warranty for 3 years. Thankfully, my other electronics of 3 years and older have managed to avoid going up in flames... I would appreciate being contacted by Lenovo support or anyone that has ideas of how I can escalate the issue. Stan

I overclock my CPU by changing its FSB and I have scheduled (Task Scheduler) this script to run every time I logon to Windows. But I would like to schedule it to downclock when I pull the power cord and then overclock as I plug it back in. Is this possible? It would also be nice if Windows changed the power plan when switching between AC/battery.

A:How can I change power plan and run scripts based on power state?

Hello Apex,

I'm not sure it's possible to have Windows change power plans automatically like that.

However, if you like, you could use either tutorial below to help make it easier to manually switch between power plans whenever you like.Power Plan - Choose from Desktop Context Menu in Windows

Power Plan - Create Shortcut to Change Power Plan
Hope this helps some,
Shawn

Hello,

I've done a lot of searches using variations of the above title and came up empty or just plain missed the answer.

I'd like to know, if it is not asking too much, the following points:

1. What exactly is the function of Link State Power Management in the Power Options Advanced Settings, PCI Express?

2. What are the implications of using the options available:

a) Off.
b) Maximum power savings.
c) Moderate power savings.
d) Which option is the best selection for my Dell laptop.

I'd appreciate a feedback on these points.

Thank You for Your time and patience.

A:Power option PCI express Link State Power Mgmt

The function of that power management feature is to manage the power consumed by your PCI devices. PCI components require constant streaming of data when in use so configuring power management to shut them down, or reduce the data stream, when not in use can save some power, which really only has a substantial effect in laptop power savings. The wireless card is usually a PCI component in a laptop, so configuring it for maximum power savings might shut it off when it's not in immediate use. This might introduce some lag into your wireless connection upon first use of the wireless or even during use (if the system decides to shut it down between connections). It's hard to say what impact it will have for you. If you're not extremely worried about getting that extra small fraction of life out of your laptop, I'd leave it alone and configure it not to use power management (keep them on all the time). Otherwise, you can try out the different settings and see if you notice a difference.

I just purchased the Spectra 13-v151nr for travel.  The charging cable is enormous relative the thin, light weight Spectra 13.  Is it possible to get a smaller cable to use when traveling?

After programming for OpenGL and a 'slow OS' case for a couple of minutes the screen went blank.

I shut it down with forcing it with the shutdown key and now there's no led at all with battery or AC, it doesn't start at all, it's totally dead.

It's most certainly not the AC adapter since that didn't show at first, it doesn't start a led at all and

If the AC is connected it does a very slight and faint clicking noise (one has to have his ear next to it to hear it, near the AC connector).

Is there any hope?

I suppose it's a burned motherboard. I suspected a burned GPU but that would still leave the leds at least lid or at least attempting to start up. Now it's totally dead.

It's a TOSHIBA satellite x200-219.
It has no warranty, as it's more than 2 years since purchase.

Hey,

I found some instructions here in forum that you could try if the notebook doesn?t start anymore:

Does it work for you?

I get a BSOD while doing pretty much anything graphics intensive... Before my most recent fresh install of Windows 7, it used to happen while playing games (occasionally while playing StarCraft II or Half-Life 2: Episode 2) but it now is starting to occur (after the fresh install) more frequently and has spread to programs like After Effects. I started to get graphics glitches while rendering a composition (which spread to other programs like Firefox) followed by a BSOD listing the cdd.dll file to blame.

My event viewer states that there have been 3 BSOD's since I've reformatted all linked to a "Kernel-Power" error. I have no idea what this is.

I am hoping this is not a hardware issue, as I don't have the money to replace my video card on a yearly basis.
