Why does Memory Diagnostic Tool turn off my laptop on its own at 6%?
Hello,
I am running Windows-7 (64-bit) on Acer 5738.
Off late, my laptop has started misbehaving. It randomly turns off on its own...without any BSOD or anything. It simply Turn Off in the blink of an eye...without allowing me to save my work etc.
At first, I thought it might be due to erratic/unstable power supply. So I did the following tests:
- I confirmed that the Main Power Supply was stable. So it was ruled out as a possible culprit.
- The next likely suspicious character appeared to be my laptop's battery. I thought that maybe the battery wasn't able to provide a stable power supply. So I removed the battery and started using the laptop on direct A.C. power.
- However, even on direct A.C. power, it did the same...it would turn off randomly. There's no pattern to it...like a fixed time of day it would turn off. So I knew that it's not related to any scheduled activity and was likely a hardware issue.
While I started investigating the Event Viewer logs for these random turn offs. However, for each one of these random turn-offs, all the Event Viewer had to say was that "The previous system shutdown at <<time>> on <<date>> was unexpected."
e.g.: The previous system shutdown at 7:55:19 AM on 10/22/2017 was unexpected.
I then came across this article:

As suggested in this blog post, I unchecked the "Automatically Restart" option. So my Startup and Recovery options are as shown in the attached image (titled "Startup and Recovery options.jpg").
However, even now, the system randomly turns off...without creating any dump files or giving me a BSOD.
So I thought maybe I should check my memory. And I ran the "Windows Memory Diagnostic" tool.
I ran it twice with the following settings: Extended, Cache ON, Pass=1.
In both runs, the system turned off at 6%. And no Memory Diagnostic logs are created in the Even Viewer.
Any ideas what my next step should be?
I tried running the Basic version of the Windows Memory Diagnostic Tool, instead of the Extended version. And the Basic tests completed successfully without turning off the laptop. Could this help me narrow down the problem to any specific hardware component/cause?
Also, even though the Basic version of tests completed successfully, I didn't find any test results in Event Viewer -> Windows Logs -> System. I right-clicked and clicked Find to find "MemoryDiagnostic". The only entries I see are those informing me that "The Windows Memory Diagnostic scheduled the testing of the computer's memory to run immediately". Are there not supposed to be any logs for successful tests?
Edit:
1. [24th October 2017 7:20 PM] I completely forgot to mention that although no logs were being created, and no BSOD is being shown, I created a Dump by following the procedure mentioned in this link: Blue Screen of Death (BSOD) Posting Instructions - Windows 7 Help Forums
The tool created the dump which is attached as a ZIP file titled "XOLO-Sat_10_21_2017_110502_23.zip".
2. [24th October 2017 7:48 PM] Before running Memtest, I just ran Windows' Memory Diagnostic Tool again. I can confirm that no errors are detected in Basic and Standard tests. But when I tried Extended Tests, it again crashed...not restart...but turn off.
