I have an Asus Vivobook Pro 15 OLED (Ryzen 7 4800H, GTX 1650 MaxQ, 16gb ram, 512gb SSD). When I bought it, it was working absolutely fine and I was happy with it. But after a month of its use, it started shutting down randomly while usage. It was overheated at that time so I assumed that might be the issue. I called Asus and raised a complaint regarding the shut down issue. This is a creator laptop and it shut down while using Adobe After Effects. The engineer checked my laptop and run a stress diagnosis and the laptop shut down while the diagnosis was running. So they took the laptop away and changed the motherboard. The issue still persisted. This went on for months. They changed the motherboard (twice), keyboard, display, adapter of charger as well everytime. I took it back to the service center. But the issue still persisted. They raised a complaint for each specific part everytime instead of nothing it down as "shut down, reason unknown" instead, they just ordered new parts and changed it everytime and wrote it down as issue solved, and the issue still existed.
They serviced my laptops several times changing the thermal paste as well. It was of no use. So I talked to a higher authority in Asus through call center agents. They scheduled a call with me in 3 days time and after a thorough discussion, they mentioned I should give them a video proof of the issue and they’ll see what they can do and still I specifically mentioned that it’s defective and replacement would be a better option. They said, we can’t promise you that but we’ll see what we can do regarding the same. When I sent them a video proof of it shutting down, they simply declared that the video is old and rejected everything that I said even though the video has proof of me sitting in front of it, date and time of the video and it shutting down and me booting it up again. They said the most they’ll do in such a "fake" case is they’ll extend the warranty for some time (spoiler alert: they extended it to just a month). So the issue still exists. I bought a laptop before this which was Asus TUF A15 and in one day of its arrival, the speakers stopped working. When I put it up for return, I got the refund of 70, 000rs after a month.
After the Vivobook case, I recently bought Asus ROG G16 Laptop (i5 13th gen, RTX 4050, 16gb ram, 1tb SSD) and it’s battery stopped working in a month, so again I raised a complaint (AGAIN) and they took it back for repair, I gave them all of the details of my experience and they said "bring your Vivobook, we’ll fix it as well, I know what the issue is" (ps: this was a different service center). So they took my Vivobook, handled it poorly, said that it needs servicing, took 800 bucks from me (which is fine for servicing) changed the thermal paste and when I took it back home, all the screws were loose and the back panel was loosely fit. Coming back to the ROG laptop, they said aux slot popped off when they opened it so they ordered a motherboard (on their own) and changed it, and are now waiting for Asus’s approval. Two days later they call me and say "Asus did not approve it, you’ll have to pay". I was not included in this motherboard thing. They even sent me a bill for it through email. I talked to several agents and finally fixed that issue that it wasn’t my fault that happened. I bring that laptop back home, after using it heavily for 1 hour, it shut down (this is the ROG laptop) and ps, the Vivobook laptop now shuts down more often. Both these laptops are up to date with their systems, bios up to date, all up to date drivers, both have thermal paste in them, no overheating when it shuts down most of the times and error logs just say "unexpected shut down, so no log could be created".
This has been my experience with Asus and I specifically suggest you, you’re lucky if your laptop doesn’t shut down on its own. Because of it does, Asus would never find a clear solution for it.
