The laptop is randomly shutting down

Hello,

About two years ago I bought Aorus x7 DT v8. One month ago, I had to remove the battery since it has inflated and I've been running directly on the power adapter ever since.

Recently, the laptop started randomly shutting down, while gaming or just watching Youtube, and the weird thing is, I cannot power it back on unless I disconnect the power cable and wait 2-3 minutes. Just yesterday, it shut down twice.

The laptop is not overheating, since I'm constantly monitoring the temperatures and cleaning the fans and heatsinks on a regular basis. The CPU and GPU are not overclocked.

It's very hard to tell what could be causing these sudden shutdowns since there is no message or anything. It could be the power adapter itself, but I did measure the output voltage and it showed 19.1V, while on the adapter it's written 19.5V.

I would gladly test with another adapter, but the one that came with the laptop is 250 watts, and not a single store in my country sells such adapter. I only found the same one on Gigabyte US store, but they don't ship into my country (Slovenia).

Also, do you think the laptop may try to switch power over to the battery, and since there is none, it turns off? Even if so, why starting to do that now, and not when I removed the battery over a month ago?

At this point, I'm not sure how to troubleshoot this...

Any thoughts?

 

Hello,
I don't think your lack of battery is causing you these shutdowns. If you have to wait some time before you can turn it on, it seems a security. Monitoring your temps will not say you if VRM is overheating for exemple.
If you have a LED indicator on your 250w adapter, then it can be helpfull to see if the LED is still ON or not.
Maybe describing your config can help too (CPU, GPU...)
If your battery has inflated, it can be a sign of something wrong on the supply or on the main board.
I can be wrong, wait for others to confirm

 

I see. I don't see how VRM could overheat, because yesterday I left the laptop in an idle while having dinner, and when I came back, it was turned off. I checked the LED on the adapter and it was still on. Also what I noticed, these shutdowns occur in the evening hours, meaning after around 8 hours of regular work (not gaming).

Today I got a reply from Gigabyte eSupport, and they said I should first update the drivers and all that, which I did, and if the problem still persists, I should do a completer reinstall of Windows. I'm planning to do that later today, but I think this is a hardware related issue. My last resort is to send it to the repair centre.

 

I, too, think of a hardware issue.
If your adapter have a removable cord, you can try changing it.
If the LED was ON when you came back doesn't mean it was not OFF when the shutdown occured, then ON 2-3 minutes later.

 

Fair point. I could replace the removable cord, but I don't think this is the cause. I will keep an eye on the adapter when this happens again.

 

Hello there !

I started having the EXACT same issue after 1 day !!! (05/11/2020)

its just heart breaking and annoying I am still facing it and cant do anything actually without worrying "it may shutdown any sec".

Yesterday it did shutdown during 1 of my online Final exams, that was so frustrating.

What I did in hope of solving this issue:

1- System restore to a stable point.
2-Un-did my Undervolt which was stable for more than 2 years.
3-Updated windows 10 to the latest version.
4-Updated all my outdated drivers.
5-Cleaned my already clean Fans and checked for overheating issues which doesn't exist because temps are at mid 70s for CPU and GPU under the heaviest load (stress testing - benchmarking - heavy tasks).
6-Disabled intel's (Speed step) technology that is responsible for turbo boost, after noticing Huge fluctuations in CPU core Frequency when the laptop switches the power source to battery (from 3.7 GHZ to 1.97 GHZ).
7-Removed all Viruses and malwares by using Bitdefender and Malwarebytes.
8-Removed the latest programs and games installed before the issue started.
9-Went to a local technician and tested my power brick and it is supplying steady voltage (19.55v), I am still a little bit skeptical because he tested it for 4~7 seconds only.
10-Tried operating the laptop on (Battery alone - AC adapter alone - both together) after disconnecting all the power sources and holding the power button for a minute to discharge (every time between iterations).
11-Disabled all the services when booting into windows.
12-Completely removed Nvidia Graphics driver using (DDU) and performed a clean installation of an old stable driver.
13-Completely unplugged all the USB peripherals.
14-Uninstalled all the USB drivers to check if its a problem of drawing more power into (headphones-mouse-keyboard).
15-Ran Intel's CPU diagnostic tool and it passed.
16-Tried to do normal operations (Idle- play a game - watch a movie - run benchmark) with these 3 settings (GPU on normal clocks - GPU underclocked - GPU overclocked) No differences at all between the 3 conditions.
17-Changed the (Travel adapter) that converts my power cord from UK plug to a European one.
18-Ran RAM diagnostic tests and passed them.
19-Ran ("Error Checking" and "Optimization") on my HDD and SSD, and all is fine.
20-Tried normal operations under ("Optimal power" and "Prefer maximum performance") in Nvidia 3d settings.
21-Tried turning Off G-Sync
22-Booted in the device in safe mode, yet the problem remains.
23-Reseated the CMOS battery.

and it was all in vain, it still happens, I cant think of anymore solutions and I cant afford replacements for my machine its only 4 years old!

So kindly if you found the solution share it with me

oh, btw this is my first post on this forum =D

 

I kinda figured it out what was the reason in my case. The day I received a new battery, I installed it, but when I was cleaning something behind the laptop, I accidentally moved the power cable, and the laptop switched its power source to the battery.

When I noticed that, I started to bend and rotate the power jack a bit while it was inside the power port, and at the same time I was observing the battery icon on the desktop. And surprise surprise, the icon was changing from charging to battery. I mentioned this in my email with the Gigabyte service centre, and I asked if they could only replace the power port, and they said no because there are no spare parts available or something like that.

What I did afterwards, I cleaned both the power jack and port with alcohol, and now it's been working ever since.

But I'm speculating there might be another reason why the power might cut off. During gaming, the area of the back plate, just under the power port, it can get quite hot, and I'm suspecting that the power port itself expands just a tiny bit due to the high temperature, and thus breaking the contact with power jack...

 

Thanks for the fast reply !

But my laptop and all its ports are Spotless!, and the My temps are 78 Degrees or lower I dont think thats the problem...I will keep doing trial and error sadly..

 

Wonder if its because the battery was removed, I know the bios is programmed to use the battery for energy sharing. If the system detects a variance in voltage and performs something specific such as internal test it could quickly switch to the battery power then die because its not present in the system. Just a hypothesis though.
