Question Acer VN7-571G - turning off by itself without warning and doing a restart

[xMooN]

Hi!
I'd like to ask something about one of my laptops, the "VN7-571G", which is behaving abnormally. It turns on and I can use it for a while. I upgraded the hardware of the laptop to be more responsive and reliable, but it turns out that it's not reliable at all. It originally had 8GB of RAM, a 1TB hybrid SSHD and a WiFi 5 card. I upgraded the RAM to 16GB, installed a 128GB SSD and instead of the SSHD, I installed a normal 2TB HDD for files. So far so good. Then I cleaned up the fans and replaced the thermal paste with some fresh Arctic MX-4. Proceeded to upgrade the WiFi card and installed a Intel WiFi AX200, which works perfectly fine as well. But..

The laptop turns off for some reason as if it would not get enough power. The battery was old so I got a brand new battery to replace that as well, but yesterday it did the same thing again! Even with the new battery.. And it ridiculously showed me 76% of battery wear level after turning off and and on again! (which was the same wear level it had with the previous battery, but sometimes it showed 13% as well)

And now the laptop simply does not work reliably. It simply shuts off without any warning. Just like it would be a restart, but without warning. I don't really know what to do next. I didn't damage anything on the board as I'm sure that I have disassembled 800+ laptops, for repairing and/or cleaning the inside. But I don't have any information on what could cause that issue. I mean.. if it would overheat, it wouldn't turn on again instantly after it shuts down, right? And why does it still think that the battery is "bad"? The battery wear level fluctuates from 0% to 75%, this is really the first time I'm experiencing something like that.



Do you guys have any ideas?



Then please let me know!



Regards,

Emre

Does it have this behavior if it is plugged in? It could be overheating, stopping and restarting is one behavior of overheating. Have you tried setting the power setting to high performance, perhaps it is not getting enough power call during use? If you install hwinfo you can monitor your temps and see if there is overheating somewhere. Is there a pattern to it shutting dsown such as while gaming, browsing etc?

Unfortunately, it does the same while it's plugged in. It's not overheating, I ran some tests and it reaches a peak temperature of 76°C but quickly cools down. There's no pattern or a way to reproduce the issue, it happens randomly but very often and within the first 10-15 minutes after powering on. Sometimes it's even turning off after 5 mins. But why would it turn itself back on again after turning off? I mean, if it's a overheating protection, then it shouldn't turn itself back on, right?

I think that there's a problem with the battery circuit. Laptop always "thinks" that the battery is low or there's some abnormal battery status detected by the system. The orange light blinks for no reason although the battery is full. It did not turn off while running yuzu emulator while plugged in. I don't know why, but it used to turn off on AC as well.

The only other thing I can think of is your power call may be pulling more than it can produce since installing newer parts.

Is there any chance to fix that?

You could try changing the power setting in windows/laptop controls to use high performance, or balanced to see if it changes the behavior at all.

I guess that I've fixed it by power cycling it twice. Used the battery reset button on the back of the device, that was probably needed as the system was (most likely) reading old data from the battery. It hasn't been turned off by itself since that. I'll test it for a minimum of one week and then decide, whether it's fixed or not.
