Yoga 500-15IBD sudden power off

Question: Yoga 500-15IBD sudden power off

I bought a new Yoga 500 15IBD 2 Months ago and since a view weeks the Laptop had several power breakdowns while in battery mode. All of a sudden the Laptop turns black, all lights and the hdd turns off and I have to connect the power cord to get it started again - although the Battery certainly isn't empty according to the OS-Battery indicators AND often having the Laptop fully charged less than half an hour ago. (The Yoga runs for at least 3 hours if the bug does not appear). Now this is no driver issue, I have the problem while running Windows 10, Linux Mint and Backbox Linux. I suppose it's either a battery issue or a faulty architectual design. Since I see a lot of similar power-off related messages accross the spectrum of lenovo devices, could someone finally publically explain the source of the problem so there is a chance to get rid of it ... especially in future products?

Preferred Solution: Yoga 500-15IBD sudden power off

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 (This link will automatically start a download of Reimage that you can save to your computer.)

Earlier today, I had shut the lid on my Chromebook (putting it into standby mode) and had put it away. At this point it had full power. About half an hour later, I had opened it up again, but it had shut off, and I coudn't get it to turn on again until I plugged it in to auxilary power. When it revived, it still had full battery, but had forgotten the details of the network until I had signed in. This is similar to another issue, wherein the system will occasionally stop opening and running user-installed applications and block any access to local storage (such as viewing and downloading files), citing lack of permission (which does not apply otherwise), until restarting and logging in again. My device is fully up-to-date on the stable update stream. Why am I having these issues? Are there any ways to fix this permanently (aside from purchasing a different device)?

Answer:N23 Yoga Chromebook - Sudden shutdown, won't power on without charger; no local storage access?

EDIT: The shutdown seems to be caused by overheating, from what I can tell. Is there seriously no heat sink on this device? For shame, Lenovo.Still no idea why local storage keeps breaking, though.

I recently bouht refirbished Yoga 500-15IBD, It has Intel HD 5500 and GeForce 940M. When I bought the laptop online I was under the impresion that the display is FHD. Unfortunatly the maximum resolution that I see in the Windwos 10 display settings is 1366x768. Is this a software issue or the display is not FHD? I am wondering if it is possible that seller changed the original FHD display with HD display. I can't find the full spec of the laptop. Machine Type Model: 80N600FWUK.

Hi, I've tried looking for tech specs (I know the hardware specs) for the monitor so I can work out what pen/stylus would be best for the touch screen. However, I can not find this particular product (spec specific) on the website.  If anyone could help me out that would be great, Ideally I'd like something with pressure levels as I do digitally draw from time to time, and would be helpful whilst writing. But would settle for something that isn't due to owning a GFX tablet anyway. Also, I'm unsure if this ideapad is referred to as a 15, 500 or 8 due to not know where this terminology is based from (model name, model series ect) seems unclear, perhaps I'm just looking into it too much and it is just a 500. Thanks to anyone that spends time reading, and thanks in advance for advice. ~Kris

I bought the yoga 500-15IBD(w/i5 5200U;GT 940m and 8G of RAM) in summer of 2015. At first the notebook is doing fine. But at mid-late 2016 the notebook start acting strange, the CPU start lock the frequency at 0.44 Ghz while charging. I find out that the BD prochot is the reason and I disable it with throttlestop. Then when I start gaming for few minutes the laptop just shut down, because of overheating. So I try playing game with BD prochot on and with battery. And the gameplay become very laggy. Not like low fps, but just very laggy. I monitored the CPU and the CPU just get throttled massively frequently and the frequency just go up and down. Which never happen before, the laptop used to be at least playable with consistent (low) fps.  What should I do. Is some component damaged? Should I clean the fan (I checked the fan and it seems fine to me)? Should I charge the thermal paste?  ps I try to stress test both CPU and GPU, it's fine when doing test alone. But when testing both CPU and GPU the temp of CPU just go sky high (~100 C) and the GPU seems to be cool in terms of temperature(75 C)and than the laptop shut down. Even when testing GPU only while CPU is idle both temp got ~75 C. When doing only CPU test CPU temp ~88 C max and GPU stay at ~55 C. It seems the GPU is transfering heats to the CPU.

Hi mariuszwol5, Welcome to Lenovo Community Forums. Based on what I've found out, seems like both models has same specs as you have mentioned. If I'm not mistaken, the difference here is that, the 80N60084PB has this FRU : 18201638, whereas, the 80N6006FPB does not. FRU : 18201638Description : LGD LP156WF4-SPL1 FHD AG S LED1 NB LCDCommodity Code :  LCD PANELS Also checking on the price of the part itself, based on ebay, it is around USD $99.00. Which as per google, 400 PLN = 98.21 USD.  Hope this helps!

Hi, I got a problem with my laptop. The fan is making loud noise everytime I open a new window, a new tab, any setting window and so. I believe it is supposed to make this kind of noise when I'm stressing it with more programs running, not by simply open the files explorer... Any idea on what to do? (model is Lenovo Yoga 500-15IBD)ThanksNstant

Answer:Lenovo Yoga 500-15IBD loud fan noise

Hi Nstant,  Most probably a program or App is running at the background cause fast spinning fan to cool down CPU temp.  To figure it out, right click in your taskbar and from the opened menu click on task manager.  -From top menu click on performance tab then click on resource monitor ==> from top menu click on CPU tab and look at to the Average CPU usage and see which App or Program is using a high percentage of your CPU capacity==> right click on it and end the process.  .Regards,  **If the issue has been resolved please, mark me as solution provided to help others find the solution easily and click the Kudos.**

Answer:Yoga 500 - 15IBD - Bios update went wrong

What you can see there is a Boot menu. Your laptop can't boot from disk and display boot selection menu. Try to enter BIOS (can't say how to do it, as you didn't told which Yoga model do you have) and try to change boot settings from UEFI -> Legacy (or in other way) and/or disable Secure Boot. Check if after these changes your laptop will be able to boot.

I recently upgraded my Lenovo Yoga 15-IBD to an SSD, with a complete reinstall of Windows. Everything was working great; boot times were quicker and the system was far more responsive. However, the computer randomly freezes now, without any warning. I have to do a hard reset. Reliability monitor gives no clues of what the problem might be. The SSD is brand new, and passed a 'long' test this morning.

I have no idea where to go next; I seems that there is one problem after another with this laptop!

Thanks for your help!

Answer:Lenovo Yoga 500-15IBD Freezes Randomly after SSD Upgrade

Hi soopg.

When it freezes is there anything being logged in the event viewer? (System / Application / Other)

Have you looked at your Storage drivers. Before attempting to update please ensure you have an Image you can fall back to if required. While investigating would also be a good idea to have data backed up. You said this was a clean install so you likely have that point covered.

If you don't have a tool you could check out Macrium Reflect. Free, reliable and tutorial with forum.

You may wish to check out the Driver Verify process.

This tutorial will guide you through the verification process, heed the warnings. Assuming it fails follow the posting instruction in the BSOD section of forum.

Driver Verifier - Enable and Disable in Windows 10

The tutorial states make a restore point. Seems to be a lot of people having issues using restore points hence have an Image.

Answer:Lenovo Yoga 500 15IBD mystery restarts (BSOD)

Is this while running idle or under load? What surface is it being used on? (getting at ventilation) Leaning towards heat, but could be power issues or something else. Scape that, just noticed the dropbox links (its been one of those days) if memory serves bad_pool_caller is a processor 'misfire' Check in device manger that the processor is running correctly (ie flags 'device is working properly' this is stated in the devices properties (right click DM entry) ) if need be,uninstall, and have windows install them (this can be done in the right click menu of the device in DM selecting 'update driver software') Normally if this doesn't fix the issue its very often software based, ie something installed is causing the issue, bad drivers probably the top contributors, but not exclusively. Posting the .dmp file (google is your friend) would almost certainly flag the culprit.

Hi everybody, when I unplug the charger on my yoga 500 the screen starts to flicker like a rave party, I have searched like crazy all over and have found no solution to the problem. Things already tested:-Unplugging and plugging battery cable.-Disabling Windows error reporting service and Problem reports and solutions-Trying to update intel drivers from driver section and intel site.-Trying to update, and disable realtek hd audio driver. Things to take in account:-When connected to a second monitor, the new one won't flicker.-Laptop has warranty voided because of ssd install. (problem still occurs on bios with and withouth an HDD/SSD) so it shouldn't be considered a Windows 10 problem.-After SSD install, windows update doesn't allow me to update anything. I believe it thinks I'm booting from external hard drive.

My Yoga 500 ideapad totally loses it when I plug it into power. The CPU slows down imidiately and runs at 100% usage every time I make an action (opens Chrome takes like 30 seconds). In Speccy, I can see, that the CPU runs at a speed of approx. 500 Mhz (Core speed). If I unplug the laptop, the speed goes up to like 1,9 Ghz when I opens chrome (chrome opens instantly) and CPU usage maxes out at 40% or so. I can now close Chrome, plug in the laptop once again, and if I open chrome now,it maxes out at 500 Mhz speed with 100% CPU usage. I have just completely reinstalled windows (10, 64 bit) hoping that this would solve the problem.

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'm having trouble with the battery on my satellite P10. I can use the Notebook fine when I am on AC power but when I want to run it on battery power, it will last a while ( showing 100% and slowly decreasing as normal) then will suddenly change to 5% and switch off due to critical battery level.

Can anyone help me?

I wouldn't of thought it is just a case of needing to replace the battery becasue it has suddenly gone like this, it hasn't got gradually worse over time.


Answer:Sudden Power loss when running on battery power on Satellite P10


How old is your battery and how many times did you charged and discharged the battery?
Usually after a one year or after 500times of charging/discharging, the battery slowly loses the performance?
In my opinion this is a simply battery issue and the battery must be replaced to solve this problem?
Simply contact the ASP in your country and order the new and compatible battery!

Hello, I have recently come across these power related problems on my Lenovo Y510P: i7 Model, 8GB Ram, GT750M configuration. ---- It first began after I installed a new SSD to the system, clean install of Windows 8.1 with all latest drivers except previous version BIOS and Lenovo Energy Management. Before all of this began, the battery would not charge; I troubleshooted and fixed this issue by removing the battery and holding down the power button. Over the next few days, I began to have additional issues. When I unpluged the power adapter, the system suddenly powered off. Here is what occurs: 1. Power up system with adapter plugged in and battery attached.2. Unplug adapter3. Quickly replug adapter4. Quickly unplug adapter again.5.

Hi everyone, i am using lenovo laptops for more than 10 years for me and my family. Never had any problems before i bought Yoga 2 Pro machine. All these flickering issues, yellow color instead of white, constants bios upgrades, SSD replacement during the warranty - not the whole list of issues with this machine, the others, by the way, work perfect  Now, after more than a year of Y2P usage i am out of warranty and have new problem. The laptop shuts down suddenly, without any reason, there is just black screen and nothing more.What i tried to do:1) To clean CPU fans (thought that may be there can be an overheating problem) - they are fine, the temperature is steady around 70 C2) To connect/disconnect AC adapter and internal battery - the problem is still here, the laptop continued to shut down occasionally3) Connect/disconnect SSD (during this time the system was booted up from usb-flash) - the problem is still here, it happens even without SSD4) Disconnect wireless card, update and reflash bios - nothing helped. It`s an EPIC to have such problems with more than $1000 machine, the others, which i have in my family (more than 4 here) work perfect, but these problems and finally, the last one (unexpected shutdowns) makes me think that high-end Lenovo laptops is not an option for me anymore, paying more than one thousand you get only one year warranty and continious problem.Anyway, did anyone has any suggestions what to do next? P.S.: going to Lenovo serv...

If you have experienced sudden shutdowns with your Thinkpad Yoga S1, then this test may help.
I experienced several sudden shutdowns during normal usage. The thinkpad has never been dropped or damaged in any strange manner.
After the shutdown, the power button would not respond immediatly, but eventually you could power the thinkpad again.
Test to reproduce the shutdown
-Put thinkpad yoga in laptop mode
-Power up
-Hold thinkpad with your right hand, having the thumb on top and the 4 fingers below the laptop, landing on the grid at the back. As shown.
-Lift thinkpad above table with one hand (the right one).
Shutdown occurs
Would lenovo replace the whole unit (bought in June 2014).

If you do not have any LED lights on the front lower edge of the notebook it means the AC adapter is not charging the main battery.  You can try the following steps to correct this issue.

Make sure the AC adapter is working, try a different plug (source) to use.  If the AC adapter is not working the battery is depleted and will not allow the notebook to turn on.
If the AC adapter is working (producing DC electricity) and the notebook does not show a light to indicate it is charging then it may be an issue with the connection on the notebook for AC power has failed and needs to be serviced.
If a LED glows white on the lower front edge when you plug in the AC adapter, but the battery will not charge it indicates a problem with the charging circuit or the battery.  Check for damaged or bent pins on the battery connection.

If nothing works, it means you will need to send the notebook in for repair as it may have a main system board issue that will require replacement.  If you need to save your user files, do so by removing the hard drive and using a different computer with a USB... Read more

Question: Sudden Power off

My PC shuts down randomly when playing GTAV,sometimes during the day it can stay on for 2-3 hours without going off,sometimes lets say during the same hour it shuts down every time i start the game (like 1 minute or 5 after loading the game) and sometimes it never shuts down like it has it's own mind,so far i have tried the following:

Checked all cables.
Removed DRAM's(have 16GB,used only 2 then switched with the other 2).
Removed OC profile in BIOS.
Disabled Anti surge from BIOS and used a power plug protector(electricity is very stable)
3 clean OS install.
Tried different Nvida driver versions including all settings.
Everything is up to date.
Cleaned all components.
Tried another wall power point.
Changed the cable connector between the wall and PC.
Non heat issues.

This is what i see after the shutdown

"Power supply surges detected during the previous power on.
Asus Anti-surge was triggered to protect system from unstable power supply unit!
Press F1 to Run Setup"

The way it shuts off is as if someone pulled the plug out of the wall,i've posted about this some time ago thinking that the issue is gone but it has come back now,is there any way to fiind out the cuase for this ? thanks.

Hello all, About a month ago, the DC power jack on my friend's Yoga 13 broke. (It's not all that well designed, honestly--for a part that is subject to frequent use, having a tiny piece of plastic in the middle of the jack really stinks, IMHO.) Unfortunately, she only noticed this after she'd decided to drain the battery before recharging it. Needless to say, she couldn't charge it anymore.  Since I'd already gone inside the computer to upgrade memory and hard disk space, I took another look and thought it looked like an easy repair. When the part finally arrived, I figured it'd be an easy fix. But no. The computer is a dead as it was before. Not only won't the machine turn on, even the light that is supposed to come on when the battery is charging doesn't light up. Even with the battery disconnected and the cord plugged in, it won't start. Today I even dug out a voltmeter and from what I can tell, there is power everywhere there should be, including off the motherboard to the battery cable, and to the switch that turns the machine on (which is on the keyboard bezzle). Obviously this is only true when the power cord is plugged in. The battery itself however still tests as dead (assuming I'm doing that test correctly), despite leaving it time to charge.  So now I'm stumpted. I'm thinking that the consitent volt readings I'm getting are misleading, and that there's some sort of short nonetheless. The laptop is just a year old, so I'm totally confus... Read more

I have a Gateway NV79 laptop. In the past couple of weeks I have been experiencing a problem where the computer randomly powers off. It happens most often when watching videos on the internet, but has happened once or twice in other circumstances. I am running Windows 7. Any thoughts on how to identify the cause of this problem would be appreciated.

Answer:Sudden power off problem

This is usually caused by overheating. Blow out all fans with a can of compressed air. Make sure the bottom of the laptop is well ventilated. Do not use the laptop on carpet or a bed. Consider a laptop cooling pad.
Try a Clean Boot. If that solves the problem, add one startup item at a time till you find the culprit.

It will do this once only... subsequent pressing of power button does nothing, HOWEVER if i disconnect power to the wall and reconnect, it will do the same thing.I opened it up and the processor, PSU fans all start momentarily and then die.No other equipment in the house flickered at the time (like lights or TV).Am I right in thinking it's the PSU that has suddenly died?

Question: Sudden power issue

(I've searched the forums for a couple of hours, with no luck, before posting) I have a T61p which has worked great for a few years.  Suddenly yesterday, it refused to power up:  a cold boot goes like this:  to start, only the power-plug light and battery lights are on.  When I press power button, the Z-with-a-circle light and the caps-lock and num-lock buttons flash (with a faint click), then then, with another faint click, the caps-lock and num-lock lights go off -- and nothing else.   I've taken out the battery, unplugged the power cord, drained the laptop by holding down the power button and plugged the cord back in -- same result (except the battery light isn't on, of course).  Today, putting the battery back in only makes the battery light flash orange, making me think it's not charging, either. Am I deeply hosed?  Should I now start asking about how to recover my data from the hard drive for my soon-to-be-newly-purchased laptop?

Question: Sudden power loss


I'm putting together a computer for my dad out of a few parts I no longer need and was creating a new partition on the hard drive in preparation for a format and installation of Windows.

However, whilst the the partition was being created the power died. Now the machine won't switch on. There is a red LED on the motherboard that lights up when the power button is pressed and the processor fan twitches, but doesn't start turning. There's no power to the CD-ROM drive.

I've tried disconnecting all disk drives, removing/switching position of RAM etc, but nothing seems to work.

The case and power supply are new and the machine was working fine for 30/45 minutes prior to this happening.

I'd appreciate any thoughts - I'm afraid it might be a problem with the motherboard, but am not really sure.

Of course pressing the power button still allows your PC to shut down correctly whereas a power cut does not.

Windows has suddenly changed the way the computer powers down and boots. I am the only user of the computer and do not use accounts. In the past, when I click "shut down" I was prompted with three icon options (shut down, stand-by/hibernate, and restart. Now I am prompted with a pull-down menu with these options plus "log-off" with my name as a user account.

Similarly, in the past, when booting, the system went right to my desktop. Now it either prompts me for a (non-existent) password, or brings up a welcome account screen with my name on it and asks me to load my settings.

I've tried changing settings in user accounts (unchecking use welcome screen) and also change the setting in power options that requires a password in recovering from a stand-by. None of this helps. I also note that there is an account called "ASP.Net Machine A" alongside my account and Guest account in User Accounts. I don't recall seeing this before. What's going on?

Hi, I recently bought a U410 which was working fine apart from a random loss of power. The machine would switch off suddenly in a number of situations (both when being used fairly heavily and when idle) and both under battery and mains power. When it switched off the machine was not excessively hot. When turning it back on the machine booted fine, had adequate battery power and did not report anything in the event logs other than an unexpected shutdown. As the machine was only a couple of weeks old, I returned it to the store and (with a bit of convincing) managed to get a refund. Since this appears to be a fairly isolated issue I bought a new U410 but unfortunately within a couple of days this one was also experiencing the same issue. I would rather fix the issue than take this one back since the U410 is otherwise a very nice machine. After a bit of research on these support boards I found a few threads referring to different potential causes, but no definitive cause. Everything tried so far (fully updating drivers, bios, windows etc) hasn't alleviated this issue. Did any definitive cause of this issue ever get found?

Answer:U410 sudden loss of power

hi stevejefferies,
Welcome to the Lenovo Forums.
Most intermittent shut down / power loss issues that I've encounted is due to overheating or a faulty component inside of the PC.
Here's what I would do if I was in your case:
1. Monitor the temperature of the HDD,CPU,GPU by using HWMonitor.(the Core i-series CPU has a TJ max of 100 C before the unit shuts down)
2. If there's no sign of overheating, eliminate the OS and the preloaded apps as the issue by doing a fresh OS install. If you're running Windows 7, you can get a Windows 7 ISO on this website then install all the drivers (keep windows update disabled for the meantime) and observe.
If the issue reoccurs, I recommend you contact lenovo to report the issue and have it serviced.

Hi Dimitri,

Sudden power downs without the normal shutdown process occurring can be caused by over-heating. Check that your notebook is not blocked with dust and debris in the area of the air intake fans and CPU heatsink.

Anyone know what might have happened? I had changed the settings a couple of weeks before this so I know they were working recently.


Answer:Power settings all of a sudden disabled

Is this a laptop or a desktop?? Well, regardless, it's probably the ACPI drivers which are usually part of the chipset software. ACPI controls power saving features. Check your device manager for any yellow question marks under system devices.... If nothing else, try a system restore to right before the problem happened. Also, check your system BIOS and see what the power settings are in there: it could be that the power saving options have been disabled.....

Hello, I am using my girlfriends HP 530 laptop to write this. Basically, the problem is that since installing Windows 7 from Windows Vista, the laptop has been cutting out without any warning. It isn't going into standby or any other power mode, as it starts from bootup when pressing the power button afterwards. This occurs even when the battery is almost fully charged and plugged into the mains.

I have tried flashing the BIOS to the latest version. Recently, the laptop was displaying these symptoms from overheating, but the laptop was also making a really loud sound. We had to dismantle it and found that a large amount of dust had clogged up the vents, which we immediately removed and then put back together. This was only two months ago, since then we have not been leaving the laptop on soft surfaces such as duvets etc.

I have no idea what this could be, I have changed the power saving settings and updated all the drivers.

My PC isn't new. That said, I've kept it alive and reasonably healthy, sometimes with the help of the fine folks here, with high rate of success. Enough preamble, the new(ish) problem follows.

Periodically, with no warning signs and no error messages I've been able to locate, my PC will just shut completely off. I once investigated this same problem with the thought that it was originating from the power supply. Ultimately, even though I couldn't prove it to be the power supply as the source of the issue, that's what I replaced. This didn't fix the issue.

After watching the event happen for some months more, I began to suspect possibly a graphics driver issue. I play quite a few games, and I use AMD and ATI rather than more popular chipsets. The crashes almost always happen when I'm gaming, and seem even to happen more reliably playing some games than others, and even some VERSIONS of games than others. I've tried replacing the drivers with the latest suggestions, no improvement at all was noticed.

i have an emachines w047, with xp. i am going to give a series event that i have no idea if they are related or not. first, 2 days ago, my computer lost its network connection while it was in use. after restarting a couple of times, it worked again. the following morning, i lost my network connection again. after some effort, i got it back. then last night, the computer lost the internet connection while i was using it. i tried to restart, and it froze up in the middle of booting up. i kept trying to reboot, and eventually got the BSOD. the error said something about NV_4. (unfortunately, i did not write this one down) i tried to do a system restore, but it froze in the middle of it. when i got up this morning, i tried starting it a few times. sometimes, it would seem to boot up, never with a network connection, then i got the BSOD again. this time, the error was PAGE_FAULT_IN_NONPAGED_AREA. i got this error a couple of times in between it almost booting, then it would not even start. when i turn it on, the fans cut on, and the yellow standby light comes on, but it never goes any further. now, that is where it's at, in a coma, or on its deathbed.
any suggestions on what to do? i have thousands of photos on there that i need to retrieve.

Answer:sudden death of power supply???

Emachines are notorious!!!! They are cheaply made with the cheapest components!!!! If the psu (power supply unit)has died then it will almost certainly blow the mobo (motherboard) too!!!!

If it is still under warranty then get Emachines to fix it, if not, it's probably gonna cost!!!!

I am using Windows 7 Ultimate 32 bit on my HP 6910p Laptop. The power plan options were working absolutely fine, but suddenly it has started to act weird. When I used to select a power option For instance , when I click High Performance: The brightness used to be full (As I Configured this plan to have max screen brightness) and when I used to switch to Power Save: The brightness used to be lowest (As I configured this plan to have lowest screen brightness)
However, now, when I switch between the plans, nothing happens. For instance, if I click high performance, the brightness remains the same as clicking the power save plan. Also, If I choose High Performance power plan and lower its brightness, and then click on power save the brightness remains same as the high performance. So, Apparently, there is no change.
Can anyone suggest me what to do?
I have also Battery-Care software installed if that helps.

I have an equium A60-692, just over 9 months old. For the past few weeks the computer just shuts off while i'm working, especially while watching a dvd. I removed the battery and restarted and worked normally. Is something wrong with the battery or is the computer not using AC power but switching to battery?

Any help would be appreciated.

Answer:Equium A60-692: sudden power failure

HI David,

There are two possible reasons for your problem,

1: The notebook may be overheating causing it to power off. This will normally be evident from increased fan operation prior to the notebook shutting down.

If this is the case try clearing any dust/debris from your cooling fans using a vacuum cleaner hose.

2: Your power system could be suffering an intermittent contact from your power connector on your notebook, thus causing the notebook to switch to battery supply even though the mains adapter is still connected. Usually this will require a power-off/restart to restore normal operation. You should notice the low-battery alarm if this is the case.

At 9 months old it is likely that dust/debris is your real culprit so I would check this out first.

If you suspect your power connector then you should still be covered by your warranty although you may have difficulty convincing your Service Agent that this is not due to 'normal' wear and tear.

My Laptop did a scary thing I was using my laptop unplugged to watch some videos before bed and while I was browsing between videos, my laptop shut off suddenly as if the battery had been popped out. It wasn't the normal, gentle low-battery shutdown that happens around 10% where it looks like the computer goes into hibernation and saves your current session, it was a harsh and sudden loss of power. I plugged it in thinking the battery was broken or something and turned the computer back on. When I did so, the "unexpected shutdown" screen showed up, as expected, and everything started normally. When I checked the battery icon, it said It was charging from 1%! What happened? How did my battery drain so completely and so quickly that it by-passed it's normal low-battery shutdown? I continued to let it charge as I ran scans for malware and such to be safe. While doing this, I checked on the battery and it said "62% plugged in, NOT charging" My first thought was "__________ I pushed the battery out of my mind for a few minutes to avoid an oncoming headache but when I noticed the icon fill up a little more, I checked it again and it said: "70% plugged in, charging" and after 5-minutes: "71% plugged in, NOT charging" and after 10 minutes: "74% plugged in, charging" Gently wiggling my power cord by the jack does not affect the charging/not charging status like other power-jack related problems I've experienced...

After looking around the internet I've noticed this problem is quite common but...
As long as I am not playing a game my computer runs fine for hours this Critical Error only occurs when I'm running a game usually after few minutes. Most solutions suggested reinstalling audio driver/making sure there is only one. Well I only have one, it's up to date with one audio device running and was reinstalled a couple of days ago. It occurs in pretty much every game but the times before it happens varies for example Bad Company 2 runs for about 10 minutes where Just Cause 2 and Team Fortress 2 run up to about an hour. Critical error is always the same and always a shutdown even though Restart On System Failure is unchecked. Here is the entire error

A couple weeks ago, the wife was using her Dell Optiplex 780m Windows 7 Pro when the power suddenly went out.

After this episode, there are two problems that I have noticed:
1. Down next to the clock, in the little "Show hidden icons" menu, when I click the little "Safely remove hardware" icon, there is no response whatsoever; then, about ten minutes later, a notification box appears saying that the "safely remove hardware" program is not responding, with a "Close the program" option.

2. If the machine is left ON and unattended with no activity for a few hours, the screen will be bluish-black and there is no response whatsoever to anything I do, at which point, I have two options --- either disconnect the power, reconnect, and then start it up; or, hold the power button for many seconds, until it powers down, and then fire it back up.

So long as some activity is going on, it seems to work fine, other than the "Safely remove hardware" problem.

Any advice and input would be appreciated.

Thanks for reading.

I have a HP DV4170us notebook computer. I have used various programs to edit and encode video on it in the past with no problem.

When I run ConvertXtoDVD 2 and attempt to create a DVD from an avi, it works fine for anywhere from 10 minutes to an hour and my computer instantly and without warning powers off. Upon reboot, I get no errors from windows, and there is no information in the system event manager. The log file for ConvertXtoDVD contains no data since the shutdown occurs instantly.

I have used QA+ 32bit to run a complete system test, including a rigorous memory test and HDD test, and have no problems detected. I formatted and re-installed windows about a month ago, and so I should have the newest drivers for all my hardware. I also used Perfect Disk to defrag and optimize my HDD.

The laptop does not seem any hotter than usual when it shuts off, and the problem happens regardless of the 'priority level' I set for the encode process in the ConvertXtoDVD options menu.

My system is a Centrino with 1GB of DDR2 RAM and an on-board Intel video chip-set.

If any more information is needed for proper diagnosis, please let me know.

Thank you very much for your help.

On 2 occasions recently my A30 has suddenly just cut out dead, almost like a power cut (although it wasn't!). If I tried to re-boot straight away it would only get to the login screen and then completely cut out again. If I then leave it for an hour-or-two (to cool down?) it boots up OK. Curiously, you do NOT get the usual 'windows was not closed down properly, now checking disk for errors' message i.e. it just booted up normally, however the 2 Word documents I was working on were recovered OK.

My feeling is that it may be a hardware fault, possibly relating to temperature? Anyone out there got any ideas? Thanks in anticipation....

Answer:Satellite A30 - sudden power loss


It could be an overheating issue. If the temperature goes to the critical limit so the OS shuts down the unit. This is an overheating protection of the Toshiba notebooks.
Well, the overheating issue is a very serious problem. I would recommend to check the cooling ventilators for a dust. Try to clean this with the vacuum cleaner.
If the problem remains so you should contact the service partner.

hi, I was on my computer tonight when it suddenly just died. No power to the tower. I hit the power button and it started to power up for just a split second then went dark again. Tried unplugging, turning off power supply, then reconnecting. Still no good. I'm guessing power supply...any thoughts? BTW, there was a thunderstorm going on but at that time there was no activity and nothing else seemed to take a flickering lights or anything. And it's plugged into a heavy duty power strip with surge protection.

I've had a T510 and a "Mini Dock Series 3" for a few years. It has worked fine. However, I recently upgraded to the "Mini Dock Plus Series 3 with USB 3.0" and have an approximately 50% chance of my T510 losing power when connecting or disconnecting. This is a hard cut as soon as contact is made or broken with the docking station. Occasionally it works (though I'm reluctant to keep tempting filesystem problems). Has anybody else experienced a similar issue? It looks like in the past, the T61 had a known issue that caused IBM/Lenovo to issue some rubber nubs to cover the metal pins on the docking station[1]. I could try the same here (simply with electrical tape, or some heatshrink), but I'd imagine those pins are there for a reason (to ground the laptop?). 1. Regarding the new dock, I checked the compatibility list[2] before purchasing, as the T510 doesn't have USB3.0. I really only wanted to drive two external displays. The T510 is on the compatibility list for this dock. (The USB 3.0 port functions as an additional USB 2.0 port). 2.

I am having problems with one of my pcs.
The one in question is an old computer but very reliable.
It doesn't like being turned off.
This has been happening for about a month now and because it's noisey it has to be turned off when someone stays with us in our spare room.

Everything powers up except the monitor
So far the only error message I get of any sort is on the monitor 'no signal check cable connections'

So, I've bought new cable connectors for monitor into pc,
replaced power cables,
exchanged 3 sets of vga wires
Tried 2 different monitors ( Blank screen for both )
Swapped hard drives
Took out ram, cleaned it and reinstalled it
Swapped 3 different agp graphic cards which all work on my spare machine
Tried 2 monitors, 1x CRT 1 x TFT ( Both work on other pc)

So it can't be the power unit (?) because the hard drives are booting up
It could possibly be the mobo but perhaps something is wrong with the agp slot (?)
This pc's stats are
Soltek DDR Motherboard P4 2.6mhz (Mobo has no ID on it and Soltek No longer exist)
Nvidia gt 6600 256mb agp
DDR 2100 ram 184 pins with 1 gb installed (More ram can be added)

I have a T61 with a 42T4530 7.8Ah Battery. A few days ago I was using this on battery power (for about three hours) and the battery had gone down to about 15% indicated charge remaining. When I next switched the PC on I plugged in the mains adaptor - at this point the battery indicator started flashing orange. When I removed the mains adaptor there was no power. I tried an overnight charge but the light was still flashing. It seems as if the laptop is rejecting the battery. It seems unusual for a battery to have absolutely no charge and seems as if it is being rejected.

Hi All, I have a Lenovo ThinkPad T520 with Windows Professional. My laptop's 9 cell battery is just over a year old. A couple of weeks ago it suddenly jumped from the typical ~3hrs of running time on battery power to much less. The problem began with the battery draining at the normal pace to ~80%, then jumping straight to <10% and shutting off soon after. Now it can only run for <1min on the battery. Since this was not a gradual decline, I assume the problem is not with the battery, or at least I would like to try all other possible solutions. I would hate to buy a new battery and have the same problem because, actually, something else all together is causing the issue. I updated to Lenovo Power Manager 6.38, ran all Windows Professional updates, performed a single battery gauge reset (since it's harmful, I won't do it again), and tried JDay's suggestion to select "always fully charge" in the power manager. Nothing seems to have any affect on the performance. I also removed the battery and plugged in the laptop and it operated just fine, proving that the motherboard is operating correctly. I would like to update the battery's firmware to see if that would solve my problem, but the firmware I found ( does not include my T520 model. Does anyone know where I may find the appropriate firmware? Any other possible solutions? Thanks! 

Answer:T520 Battery Power Sudden Drop

Did You try option of "Perform Reset" in "Batery Maintenance"/ "Battery section"/"Power Manager" software?If there is that option in Your version of Power Manager, U should use it, after checking "Design Capacity", "Full Charge Capacity" and "Remaining Capacity" of course laptop should be wroking without power supply when You want to check that battery infos. In case of no effect - You should contact Lenovos "party-line" (service infoline ).

Hi please bare with me as I am not the most technical sounding but I try to be thorough. I am not exactly a noob with computers neither. I have an issue where I will be on the computer and then suddenly the computer loses all power and reboots. The only indication I have that something is happening at first is that I hear all my fans in the case stop (just silence) and then the computer is off. Then my computer restarts and states that it did not shut down correctly the last time and asks how I would like to start back into Windows (Safemode or not).

The only thing I can think of is the latest change to my computer which was a month ago now. My friend Dave talked me into putting in a different Motherboard for minor improvement since he got it for free and wanted to gift it to me.

I went from a Asus M3A78 Pro ATX 780G Motherboard (Chipset : AMD 780)
to a Intel(R) Core(TM)2 Quad CPU Q9550 @ 2.83GHz.

As far as I know that is all that has been changed recently.

Let me get this straight... you went from a motherboard with an AMD chipset and presumably an AMD processor to a motherboard with an Intel CPU and chipset?

Assuming that you reinstalled Windows and all the appropriate Intel chipset drivers and all your programs from scratch, the only other thing that occurs to me is that the power supply may not be working properly.

I seem to be having crashes on my laptop as of recent, but the patterns they follow are very strange. It's almost like i'm getting a BSOD while it being used, but instead the screen just go black and all power cuts. It then reboots and starts up as usual. As far as I can tell there is no conflicting software causing this, and it happens without any pattern. Since there is no Blue Screen, I cannot give a dump file. However, on the even
viewer, I see an event labeled

"Critical 8/22/2012 8:29:48 PM Kernel-Power 41 (63)"

under the critical category. Now this seems like the CPU or other internal component is overheating, But when i look at HWMonitor Pro, the CPU stays under a steady 84C under load and 60C idle. This happens in a range of occasions such as rendering videos with Handbrake to simply browsing the web. I will say this, I recently swapped out my RAM cards because the OEM one's were causing BSOD's about a month ago.

I've had two sudden restarts in the past week. The first time my screen went black, but the indicator light was still on my monitor, and my computer was still running. Sound was still coming through normally. However my fans picked up speed like crazy. I've never heard them that loud. I finally shut it off manually, and it started back up fine.

Now just a few minutes ago my computer shut off completely. It would not power back on for several minutes, even when I pressed the power button. I opened up my case to make sure nothing had come loose. Also I unplugged my PSU and plugged it back in. Afterwards it started up normally.

The only recent change I have made is an update for my NVIDIA GeForce GTX 670. It was only a day afterwards that the first error occurred.

12/14 I tried to turn on my computer after putting it on standby last night, but it would not start. All I could hear was the fans running. I had to turn it off manually and turn it back on for it to resume.

Any ideas?

Answer:Sudden restart without warning, no BSOD, no power for several minutes


Maybe high temperatures are causing this issue;check your temperatures with some software,like HWMonitor.

I would also check voltages,just to make sure you're getting enough volts (with HWiNFO).
You can download it here: HWiNFO, HWiNFO32/64 - Download ,64 bit version.
Open it and click on sensors.Scroll down until you find voltages.

Does anyone have any possible ideas as to the source of the problem for my Sony laptop, all of sudden the power has gone dead, it wont charge up, tried using another A/C charger but nothing, no lights appear on the laptop to show its charging or hibernating, dead as a dodo!The A/C charger is not faulty since checked on another laptop, and even removing the battery and trying to turn on laptop with A/C supply only is no good. No additional software or hardware or changes have been made to laptop since it was last functioning. Any ideas of possible cause. Thanks

Answer:Sony CR11Z/R laptop sudden loss of power

I don't know about Sony, but I have known the socket that the power supply plugs into, come adrift from the motherboard. This will prevent it working, and will probably need a proper repair.
