Sleep and power issues with T450; Lenovo Power Man...

Q: Sleep and power issues with T450; Lenovo Power Man...

Hi everyone; this is my first post here. I purchased a T450 (Core i7/Nvidia Graphics/SSD) last September here in Korea and upgraded to Windows 10 shortly thereafter. For the last few months (not exactly sure when it started, but I think months after I upgraded) I've had 2 system problems that may be related. #1: In my Windows power settings the computer is set to NEVER sleep when the computer is plugged in, yet sometimes (and I'm never sure when) it goes to sleep after only one minute of inactivity. I thought maybe it happened only when the battery was charging, but this is not the case. Resetting seems to fix the problem. #2: When I attempt to open Lenovo Power Manager 8 the application crashes and can't open. I need to use the task manager to end the program. Has anyone else had these problems? I'd really appreciate some help on this. Regards,Chris

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.)


Hello, I have a yoga 920 that when I put it into sleep mode the battery drains from 100% to 5% overnight.  I've looked through forums and tried to find solutions but this one appears to be resistant to previous solution or I am implementing the solutions poorly.  I tried deleting and reinstalling the Intel Management Engine Interface but still faced the same behavior.  I altered the power plan so that in sleep mode I disabled the Turn on Fast Start up.  I also changed what happens when I close the lid from sleep to hibernate and the battery stopped draining overnight.  While hibernating works it doesn't solve the sleep power drain problem.  I ran a sleep study and found that the camera was draining the battery as a USB deviceI disabled the USB always on and I don't have any other devices connected to the laptop.   Are there any other methods for disabling features during sleep that might be draining power? Thanks

Ever since I upgraded my laptop to Windows 10, this SoftThinks Agent Service is taxing my HDD to 100% slowing things down.
This is related to Dell Backup and Recovery software. I can kill this service and that's that but every-time I start up, this happens.
As for sleep mode, I will come back to my laptop and raise the lid, hit the keys, move the mouse, nothing. I hit the power button and nothing. So I hold the power button and then hit it to boot up, so clearly there are issues in relation to sleep mode and something shutting it off. (others have posted the same)
I installed all newest Intel drivers on your site and I read 1 user stated to uninstall Intel Rapid Storage, which I did. Intel Management Engine remains as I am still trying to troubleshoot. Are you testing all these new drivers you are putting out for download? Do I need to go back to Win8.1, your site said my laptop could be upgraded.
Please advise and "do the needful".

same thing here as far as the power issues. you must remove the 2 other intel things that were installed along with the Intel rapid storage
intel security assist
intel management engine something or other (cant remember the exact name) 
i still have the intel graphics and chipset drivers installed without any problems. it was just the intel rapid storage stuff that caused all the power , sleep mode problems..

This is ridiculous. I need support and Experts help. I have a brand new C930 Notebook. The laptop goes to sleep but does not wake up. Only the led light on the power button keeps blinking. I have to hard press to shut it down and then again press the power button after 10 seconds so the laptop would do normal boot. Then the Fingerprint reader does not work. The next restart works fine but from sleep still does not resume. I checked all settings on device maneger power managerment save mode and all available hardware resources are set to "Allow computer to turn off this device to save power" checked. If i change the Device manager lid close action to Hibernate, it works as expected. So computer can resume fine with hibernate and not from Sleep mode. All my device drivers and BIOS is upto date to lenovo recommended versions. I have seen some online forums but nowhere it is known if it is a software issue or Hardware issue. Lenovo Please suggest!

I have a two week old Lenovo X1 Carbon 20A7 and from the beginning after simply got Windows7 initial setup with nothing else on, I noted that if I left it to go in sleep or Hibernate, when the lid was closed, upon opening it again, the notebook screen was black although the adaptive keyboard was active and the machine was pingable from the network. No matter what I did I could not get the unit to come back to life so I always had to press the power button until it power cycled to get it back. I noted that I was not alone out there and some reported the issue on earlier X1's Support suggested to send it back and were not helping much. They decided it is either hardware or configuration issue, and in both cases it required a return.  Because the issue was reported in the forums on earlier X1's I decided that it was probably software and I started by disabling all sleep modes only to find out it would still go to sleep. This is how I found out that if the sleep mode was disabled in Power Manager, it would automatically enable in Windows version of the power manager. Disable it in Windows and it would enable in Power manager... yeah - exactly; I had the same reaction.. Same thing with other power functions. So I de-installed Power Manager 6 and bingo, no more issues. But now I get non critical warnings  in Lenovo tools that I have no power manager software installed. Plus I don't get the extra features that are useful in PM6. ... Read more

Hi everyone. Basically when the PC goes into sleep mode it often has issues coming out of it. For example when you press the keyboard or mouse it sometimes does not respond. You then proceed to hold down the power button but this doesn't do anything either forcing a hard power down to reboot.

Upon reboot the bios seems to have an issue requested on start up whether to edit settings or use default (F2) and continue. I do F2. PC goes on and stays "restarting windows" only to come up limping. Clock is back in 2004 and so forth requiring another reboot to get things back to normal which solves the problem.

Why is this occurring and should I just turn off all power save options which I prefer not to? Any advice is appreciated.

A:Issues with sleep/power save modes

Please post the make and model of your computer. Seems that your CMOS battery may be dead which will indicate the year being 2004.

For the sleep problem boot into your system follow these instructions how to delete the hibernation file (hiberfil.sys) Windows 7 - Delete Hibernation File (hiberfil.sys) - Help Desk Geek

I bought my laptop in 2015 and unwarranted, I'd like some help to get full functionality back into my laptop. While the subject states my problem, I do have some ways of getting use out of the computer:It can turn on if the battery is fully drained and after the computer is plugged in; it takes 8 days to drain. [Pressing and holding the power button only results in the PC flashing its backlit keyboard.] The battery can recharge and the PC can run on battery just as long the PC does not shut down, go to sleep, or the lid closes.Battery removal with the PC plugged in: the PC can always turn on, but when closing the lid or shutting it off, the power cord has to be unplugged and plugged back in.Additional computer information:-Windows 8.1 with updates-Installed BIOS update and Windows hotfix update from Lenovo.com

After putting my computer into sleep mode last night, I was unable to get it to boot into windows this morning. When i pressed the power buttong, everything turn on and working (all fans are functional, gpu power led is on, all hard drives & cd drives are functional. But the problem is, the screen to my monitor is blank. I also noticed that my usb aren't working (mouse connection light isn't on). I tried a soft power off by holding down the power button but no luck. The system does not turn off no matter how long I hold it. The only way to turn it off is by pulling the power supply cord or turning the power supply switch off.

My pc build:

AMD FX-6300 3.5GHz Socket AM3+ 6 core processor

Is it possible that you can test with another compatible PSU? I would strongly suggest doing so.

Also try the following steps:
?Make sure that the (internal) speaker is connected to the motherboard
?Remove all memory and attempt to boot the PC
?You should get the no memory beep errors

If the Power Supply is in working order and no beeps are present then it can be indicative of a faulty motherboard.

For troubleshooting purposes it may be a good idea to remove the components from the case and bench test to rule out a short.

Microsoft has pushed out an update for the Windows 10 technical preview that it released on Tuesday which will fix the power or sleep issues that your install may be exhibiting.

The update is out now and you can grab the bits by going to Windows Update within the PC settings and checking for updates.
This is a relatively quick patch for Microsoft seeing as the build was released this week, which makes us think that this was likely a known issue before the release. Regardless, the patch is out now and if your machine has had any issues with power / sleep functionality, this should fix it.

Thanks for this forum!  I am having trouble out of a number of Dell OptiPlex 9010 AIO machines that are deployed on my network.  They are all running either Windows 10 Enterprise version 1507 (original release of Windows 10) or Windows 10 Enterprise version 1607 (Anniversary edition).  All 64-bit OS.
The issue is that even though I have configured the systems not to ever go into a sleep state, they are still doing it and when they do, the only way to wake them back up is to hold the power button and recycle.
These are older systems, so I am considering replacing them but I'd like to know if anyone has encountered this issue under this config.  I have tried different BIOS revisions including the latest and have tried different combinations of drivers as well.
Thanks for any advice and If there is additional information that I can provide that would be helpful, please let me know and I will respond.

A:Dell OptiPlex 9010 AIO - Power Save/Sleep Issues

Reboot and immediately press F2 to open BIOS setup.
Enable USB Wake which is disabled by default. Be sure to save the change before exiting setup. That should allow mouse or keyboard to wake the PC from sleep.
And if you need even more control, go to the Power options screen in Windows, select the active power plan and change the settings for sleep and hibernation to Never, but set monitor and hard drive to turn off after a set time. And on the Advanced settings screen in the Power plan, turn Hybrid Sleep off and disable USB Selective Suspend.
And you may also have to go into Device Manager and expand the list under USB. Select each root hub and click its Power Management tab. On that screen uncheck the box "Allow PC to turn off....". Do that for all root hubs. Then expand list under Human Interface Devices and uncheck that same box for any entry that has a power management tab.

Hi there. Recently, my N22 Winbook has been having problems with charging. I originally got the "plugged in, not charging" message, and after a quick google search, found it was a common bug when Power Conservation would enable itsself, preventing it from charging above 60% charge. I didn't have any preinstalled power management programs, so I installed Lenovo Settings off the Windows store, to see if it was enabled there. It wasn't and after flipping it on and off to see if that will help, it won't charge at all, unlike previously when it would simply stay at the same charge precentage. Is there any way I can fix this and will my Warranty be voided if I take the battery out to inspect it manually?

Didn't realize the laptop was unplugged and went completely dead sitting there for a month. Went to plug in to power up and nothing. Thought maybe cat chewed on charger cable and tested it and was only pulling 4v vs the 20v it's supposed to but tried new charger that Lenovo sent and still nothing. I've heard battery could be un-chargeable if left to completely die and sit for a while but still don't get why laptop won't boot up when plugged in.  Am I dealing with something else internal in addition to a dead battery?

I’ve been having troubles with my laptop powering on and off, as well as any time I attempt to use sleep/standby mode or hibernation. The machine is a Lenovo G500s running Windows 7 x64 Ultimate, Service Pack 1. In the mornings when I try to power it on, it usually takes multiple attempts before the computer will get past the splash screen, although all the lights on the front light up as though the machine was working. Now, once it does boot, it runs pretty much perfectly, but if I try to put the machine into standby mode, the computer will never actually reach that point – the light on the front indicating that the computer is on remains a solid color, whereas when it reaches sleep mode it is supposed to blink on and off instead. Further, the computer tells me “Windows was not shut down correctly” and gives me the options for Safe Mode, etc., when I boot it, but nothing ever appears in the Event Log to help me troubleshoot this problem.
On the bright side, I have a few crash dumps from my machine, which I have attempted to translate into a readable format using Windows Debugging Tools. I have attached these files to this post. They seem to indicate I have a driver issue, but I have already downloaded all of the most up-to-date drivers for my specific machine from the Lenovo website. (Or so I believe; I also included a driver list in this post's attachments, just in case.)
I am very frustrated by these difficulties. Any help, suggestions... Read more

A:Windows 7 power state issues (sleep mode, hibernation, shutdown)

right off you should try to do a driver update.  Or roll back depending on if the issue started after an update.
For a update of drivers go to Lenovo's website, and look for the drivers and updates.
Perform them in this order as needed.
all others. (unless Lenovo recommends other wise).  The most important are the chipset then BIOS.
Do a backup and recovery/ restore before you update your drivers.  After update use CCleaner (download it here) 
Download, launch and run the registry tab. 
After all are completed shutdown again and reboot.  Still have the issue?  Make sure to check in the control pannel under hardware for the power options, and turn off the sleep mode and see if hybernate works.  Then try it again with just sleep mode working. 
Also program like Itunes, any backup tools, and antivirus programs can cause your computer to run while it should be sleeping, and error when you wake it. Disable them,
in run type msconfig and hit ENTER
Click yes if a popup windows comes up that is UAC
Then in the first tab click on Selective Startup and uncheck Load Startup Items
Then go to Services Tab and click the box that says "Hide all Microsoft Services"
After that disable all that remain.
In the Startup tab all should be unchecked.

I've been investigating an issue that my laptop has when going into sleep mode while connected to certain public networks and access points. After coming out of sleep when connected to these networks, all my network adapters will remain in an "off" state (media disconnected status in ipconfig /all), that takes forever to force it out of (I still don't have a clear remedy, it just seems to finally turn back on after multiple power cycles and airplane mode toggles).As best as I can tell, it's likely a PSP issue with the ac8625 wifi card as described here: https://www.intel.com/content/www/us/en/support/articles/000005645/network-and-i-o/wireless-networki...However, for some reason my X1 Carbon 6th Gen laptop doesn't have ANY of the common window10 power management options available... I don't have a power management tab in the adapter's properties page: I dont' have any wireless adapter power control options in the advanced power settings control panel: And I can't access any of the advanced settings in the Intel ProSet tool. Is this something Lenovo purposefully disabled?? I've never seen a computer set up to exclude all the important advanced power management features. I've gone into the messy lenovo advantage to turn off the weird airplane power saving feature, but I can't find any other way to re-enable power controls so I can adjust the PSP power settings for this adapter.

I have my lenovo x230 laptop set to sleep when I close the lid. When I close the lid the "sleep" icon on the back of the screen lights up. But the batter will not last through the night on sleep mode. Within five hours or so, the battery is completely drained and I have to plug in and boot up the system. I've never seen such poor batter performance during sleep mode on any other laptop I've ever owned.  Another thread in this forum blames the USB port that allows you to charge mobile phones/etc. during low-power states and recommends disabling the "always power on" option fo this USB port in the Bios settings. I've done so, be it doesn't seem to have helped. At least my laptop still will not make it through the night in sleep mode.  At this point, it seems my ownly option is to use sleep mode only when the laptop is plugged in and hibernation mode when on batter power, which is disappointing. I've never had to worry about this in the past with other laptops.  Perhaps/probably related is the fact that the lenovo ThinkVantage Power Manager (v. 7.16) hangs at the splash screen when I try to open it, so I've been trying to manage the power through the windows control panel power settings.

I have a Lenovo G50.  It will occassionally act strange.  The battery will start draining while plugged in.  Can't stop it but the battery will drain.  Then the unit will just go off.  I got a replacement power cord.  Seemed to do the same thing.  Will get to the point where the red battery light is flashing, it's plugged in a tries to come up but then goes off again.  Left it to sit for a while and it then came up.  Only to do it again.  Then, I took the battery out and it came up with just the power plugged in.  Then another time went to the recovery screen and wouldn't come up.  Then did.  It's up now but I need to watch the battery icon to see if it starts to drain again.  Then fiddle with the cord and it seems to stop. What is it?  Battery bad?  Power cord connection bad?  I am on a brand new power cord now.

A:Lenovo G50 Power and battery issues

Hi Jeffskyhook,
Welcome to the Community Forums.
You can have your charger checked on a different machine to check if it is ok.
Remove the battery and connect the charger.
See if you would be able to use it with power and then wiggle the cable a bit to check the integrity of both cable and dc in port.
To check the operational charging of the battery, place back the battery and connect the charger.
Allow it to charge without turning on the battery for 1-2 hours.
The battery indicator should go from amber blinking to white to say that it still have viable charge life.
Update us how it goes.

We are having the same problem with the majority of our N22s (several hundred). If we press Esc + Chromebook Refresh key + Power, wait for the yellow exclamation screen and then restart the Chromebook by pressing the power button twice, it will power up. Otherwise, they are dead as door nails.We are sending two of the Chromebooks back to Lenovo so they can take a look at what is causing them to not power on with out a powerwash.For now, we just have to keep powerwashing until Lenovo comes up with a fix or we RMA hundreds of N22s. I prefer the first option.

I've had my Y510P for almost 4 years now with no major issues ot speak of, until a few days ago. I home to find my laptop dead and my power supply making a chirping sound (NOTE: the power supply only makes the sound when plugged into the laptop) and no indicator LEDs lit on my laptop. I tested the charger with a multi-meter and it reads the ~20v that it should, but again, no response from the laptop.  I also tried the "remove battery/charger, hold power button for 30sec to discharge static" which didn't help at all. Figuring I'd start with the easiest solution, I ordered a replacement charger, that produced no better results. My multi-meter reads the charger at ~20v, I plug it into the laptop, nothing happens (not even charging lights) and strangely when I test the charger AFTER it has been plugged in it read ~0.2V. The replacement charger doesn't make the chirping sound. I figured the issue was some kind of short in the laptop's power jack, so I dis-assembled the laptop and removed the jack. If this were the problem it would be an easy enough fix, that doesn't look like the case. When I plug the charger into the now-detatched jack adn test the voltage coming out of the jack I get the expected ~20v. But if I test the jack while it is plugged into the mother board I get low to no reading. I am hoping the issue is somehow power related, blown MOBO fuse or something causing it to short out considering dead motherboards usually still charge/try to POST.

Hello,After shutting down with my battery around <12% when I next tried to boot my power button flashed 3 times and the laptop failed to power up.  I reset the CMOS and my laptop worked again. However, when ever I shutdown or suspended the laptop the power would reboot and the machine would turn back on by itself a couple of seconds later. I have now updated the BIOS but this did not help, nor did turning off wake up from LAN. I once removed the battery but this resulted in my original issue and I had to reset the CMOS again. Now aftering disabling the battery in BIOS, I am again unable to boot even after plugging in the power cable. This time resetting CMOS has not worked in getting my laptop to boot. Now I am also seeing the keyboard lights for fn, mute and mute mic all lit up even when the battery is removed and the power cable is unplugged.  Can I get it to boot again, given the CMOS trick no longer works? Thank You

My T450 always turns on keyboard backlight when I power-on the machine or even just wake it up from sleeping. I don't look at the keyboard at all, so I don't need this backlight; but worse, it just uselessly consumes some power from battery (I do work without AC quite often), and I might miss the fact that the backlight is on for hours of working on battery, that's pretty annoying. Is that intended behavior? Can this "feature" be turned off? I don't see any option in BIOS for that. Thanks

Core 2 Duo P8600 @ 2.4 Ghz
ATI Mobile Radeon 3650
Intel Wifi 5300 agn
bluetooth, and WWAN

I am running the latest BIOS: v3.13-1.06.
And also the latest drivers from lenovo and so on.

My laptop has been running fine until now. I have checked memory with memtest86 and memtest86+ and it passed the test. HD is tested also and it is good.

Thoughts, suggestions?

Initially I would have suspected memory and even though you have run memtest86 this is no guarantee it isn't memory , to quote since windows 95 Microsoft have stated about memory testing programs

Defective memory chips may not be detected by memory checking tools. Some memory checking programs are not adequate tests because they do not test RAM in the same way that Windows uses RAM. Most memory checkers use read/write cycles when scanning memory. Since Windows is executing code from memory, it uses execute cycles. Execute cycles are different from read/write cycles and are more vulnerable to parity errors. It is possible for memory checking programs to find parity errors if the memory is extremely faulty.

however your crash BAD_POOL_CALLER (c2) is often caused by drivers which have an invalid memory reference in them somewhere ?

named as the faulting module in your crash is

NETw5s64.sys NETw5s64.sys+e805 fffff880`05870000 fffff880`05f1d000 0x006ad000 0x4aafedb7 15/09/2009 20:40:39

which is your intel network driver and needs updating ?

also these drivers mostly pre-dating windows 7 release

SSPORT.sys fffff880`084e2000 fffff880`084ea000 0x00008000 0x42fbda34 12/08/2005 00:07:32

Went to turn on my Lenovo Ideapad Y410p laptop and nothing happened! No led lights with power source on and battery in. When I used it two days ago, I ran AVG and spy-bot and everything was fine. Used it a little bit and turned it off. Now nothing??? Did the power/battery disconnect with holding power button for 30 seconds... nothing. Both batteries 9 cell and 6 cell had full charge, tried my other Lenovo charger... no go. A surge couldn't have happened as the laptop is plugged into same strip as my other lenovo laptop is and that one is working fine.

A:Lenovo Ideapad Y410p won't power on... No power light?

Hi jack61 , 
We now know, power drain failed. No LED error codes , No beep codes
No activity lights even with battery charging led.
Not turning on even with known good charged batteries. 
No power even with known good ac adapter.
What we can try:
Try plugging it directly on the wall and press novo key (number 1 page 7) to turn it on instead. 
Check if the power port shows any signs of burnt / damage / looseness . 
Press Novo key using a charged battery. 
Remove battery, harddrive , memory and other accessories and plug directly with a known working adapter and or with a charged battery ( it should at least beep). 
If all fails , you can have it checked for the motherboard issue with a technician (checking on the internals /cleaning or reseating parts connected to the board / applying thermal paste (for processor isolation) / checking on dc in board and port).
You can check for your warranty here and call in tech support for service.

Hi, I have a Lenovo IdeaPad 510-15IKB that has developed some issues.  I took it apart to replace a faulty fan module, and put it back together and started having issues with video to the display not working.  Took it apart again to reseat all cables and look at the display cable and its connection to the mainboard.  All looked fine... and the notebook started fine and I had the display working again.  Then after a power recycle lost the display again, so took the notebook apart again, and found that if I removed the main power to the mainboard and reconnected it I could get the display to come back, but only until I recycled the power to the computer again, then it was gone.  Decided to just live with the notebook display not working and just use an external display via the HDMI connector, which worked fine for a few days... then the notebook just shut off.  Now it will not power back up... the AC adapter is good, verified via multimeter, I have tired to power up the notebook with the battery disconnected, no-go, with it connected, no-go, I do not get a charge or power indicator at all anymore.  I think the notebook should power up with the internal battery disconnected, yes?  It does not.  I looked in the Lenovo maintenance manual, and these symptoms point to a bad mainboard.  I can't believe that it could be bad on such a new notebook.  The fan going bad after less than a year I can live with, but loosing the main...

Hi!I recently had to wipe my system and reinstall windows 10 on my Thinkpad L450. After the reinstall of windows, I had lost all of my Lenovo programs. Including the Lenovo Power Optimized power plan, which I really enjoyed using. Is there any way that I can get that power plan back?So far, I've tried to reinstall the Lenovo settings app, but it hasn't brought the power plan.I'm really hoping for an answer because the power plan gave me about 3 more hours of usage than the standard widnows power saver plan. Thank you in advance!Kind Regards,Jes

So I have T450 (20BU-S08U00), and I face this very annoying issue sometimes: I turn off the charged laptop, grab it with me, and when I try to power it on later (on battery), it ignores me completely. I press power button, remove the battery (my model does not have the internal battery, so I can remove it easily), etc; whatever I do, it behaves like a brick. When I get home, I just plug the power cable, the power button led blinks a few times, and after that I can even remove the power cable immediately, and it will turn on normally when I press the power button. So, somehow the laptop gets stuck, and the only way to kick it is to plug the power cable (which might be immediately removed back). Could anyone please share some ideas how to fix that? Thanks

Do you have the latest BIOS?  If not, try that first.
Are you still under warranty?  If BIOS update doesn't fix it, the power circuitry may be sick.

I've recently inherited a lovely Y70-70 touch from my father, and have restored it to factory settings recently. However I'm having issues at the moment where it shuts down instantly at random times when not plugged in. Checking the system logs in the event viewer I see the following Critical message: The system has rebooted without cleanly shutting down first. This error could be caused if the system stopped responding, crashed, or lost power unexpectedly. Generally online help seems to suggest this is a power supply issue. Have I got a duff battery in here? Are there further diagnostics I can run? Unfortunately I'm out of warranty so keen to solve this myself!

I purchased a Lenovo 110S a week ago. I?ve found that I have issues turning it on sometimes whereby the power indicator flashes a few seconds but the laptop doesn?t power on. This happens with enough battery power, for example it?s happened when I have had 50% battery power remaining. I plug the laptop into mains AC power and it will then power on.  But im stumped as to why this doesn?t happen all the time. If anyone can offer help it would be appreciated! PS: my battery is a concealed one ie; in the laptop casing with a cover that?s screwed on.

Just a heads-up: I bought this Lenovo Yoga 13 Ideapad in 2013, so it's out of warranty. Proceed to read my problem..... I always get a black screen whenever I shut off my laptop and turn it back on again, which is why I lock my laptop instead. But when I DO lock it and get back on it the next morning, I encounter the Black screen of death and instead of my lockscreen immediately appearing like normal after I lock it and have left it overnight & try to get on it, I have to shut down my laptop and turn it back on because my laptop won't immedately take me to the lock screen so I can log into my computer.  Today (March 17, 2017), I had to shut down and turn on my laptop while pressing the rotation button button or the OneKey Recovery button (the button with a circle and a line going through it; I don't know exactly what it's called, but I think it's the recovery button OR the screen rotation button, on the right hand side of the computer: If anyone knows the name of this button, please let me know!)..I tried this 5 times and It wouldn't turn on. The 6th time pressing the Recovery button OR the screen rotation button on the right side of the laptop (whatever it's called), it did work and now I'm on my laptop typing like normal. But this Lenovo Yoga Ideapad 13 only works when it wants to. Is there any proven fix to this hardware issue? I was told that it was a motherboad issue, but what's the real culprit? And is the motherboard what's actually giving me th... Read more
