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 inner parts etc.. 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 or did some of you experience a similar issue?
Then please let me know!
Regards,
Emre
