Laptop shuts down and restarts on its own

I just did some more research, and it appears others have had problems with the Z50-75.  I think it is time to replace the laptop.  As always, you guys are the greatest!  Pam  Go to the full post »

I am using a Lenovo Z50-75, 64 bit  AMD Processor A10-7300 Radeon.  Since 1-29-18 the computer randomly shuts off while in use, and restarts.  This has happened sporadically with no rhyme nor reason, at various times during the day.  Today it shut off and restarted immediately after I turned on the computer. 

I was travelling from the end of December to January 22, 2018, so my computer was off during that period of time.  

 

The event log indicates a Critical event occurring.  A couple of times it read Kernal 41 Task 6 event ID.  On another occasion it said Controller Error Device HardDisk2 DR8. 

 

I tried to do a system restore to January 22, 2018, but I receive an error message about my anti-virus protection, which is only Microsoft Defender.  I disabled the antivirus and I was still unable to do a system restore. 

 

I tried to uninstall the January Microsoft updates and there is one I wasn't able to.  I don't believe the computer is overheating, and I tried using the laptop without the power pack, and I had no problems. 

 

I really don't want to do a complete restart so thought I'd see what your thoughts are first.  Thank you. Pam

Thank you for your kind response.  The computer hasn't crashed since Thursday, but I typically don't use it over the weekend as it is my work computer.  On Thursday the crash was again Kernel 41 Task 63.  Pam

By work computer do you mean that it is computer that you use for work at home, need to check as we are not permitted to help with works machines only personal computers.



 

If Windows is crashing you should be getting a BSOD and a Stop code, if yes, check for and upload any crash dmps for us;

 

1. Copy any dmp files from C:\Windows\Minidump onto the desktop.

2. Select all of them, right-click on one, and click on Send To> New Compressed (zipped) Folder.
3. Upload the zip folder using the More Options tab, Choose File then the Upload a File tab.

 

Download then run Speccy (free) and post the resultant url for us, details here, this will provide us with information about your computer hardware + any software that you have installed that may explain the present issue/s. 

 

To publish a Speccy profile to the Web:

 

In Speccy, click File, and then click Publish Snapshot.

In the Publish Snapshot dialog box, click Yes to enable Speccy to proceed.

Speccy publishes the profile and displays a second Publish Snapshot. You can open the URL in your default browser, copy it to the clipboard, or close the dialog box.

 

You are welcome btw  :)

The computer is a personal computer.   I am not getting an error message. I have been running my event log as an administrator. I tried to upload a word document with my event log but I receive an error message "You aren't permitted to upload this kind of file". 

 

I am not technically computer savvy, having learned most of what I know through googling problems, and your website helping me in the past.  

 

I believe the problem may be related to the sceptre meltdown, windows updater..but only an assumption based on the date I began having the problem.  Pam

The maximum safe operating temperature for your CPU is 102°C and your CPU is shown to be 90 °C in Speccy when the computer is not under any load, this suggests that your computer could be overheating.

 

When was the last time that the inside of the notebook was cleaned out of heat trapping dust.

 

You mention using the notebook without the power pack and having no problems, can I ask what you mean by "power pack" is it the main power brick or the AC adaptor, whichever it is it could be faulty and sending too much power to the CPU causing it too heat up in the process.

Thank you for your reply. 

 

By power pack I am referring to the adapter that plugs into the laptop and the surge protector.  And, actually I mean't I didn't use the power pack and the laptop still shut down and restarted. Unfortunately the problem is sporadic. It has occurred several mornings after just turning on the laptop.  Fortunately it hasn't happened today. The laptop has never been opened and cleaned.  We did clean the vents, thinking that dust was creating the problem.

Makes overheating even more likely to be the cause, 90 °C when doing nothing is really hot.

 

Not sure if you will find any temperature readings in the BIOS on your particular brand and model of computer, if you know how to get into the BIOS have a look and see if there are any temps readings and if so what they are.
