I have a model Acer Nitro V15-51-541P with i5-13420H and RTX 4050 Laptop. I bought this laptop just a month ago.
Unfortunately, I had an experience with problems of sudden blackouts while gaming while the fan is still on (probing me to look at a GPU problem). I've already updated my graphics driver, and I have bought a cooling pad (llano v12) to somehow resolve the problem. However, it still persists.
I had to go through acer customer service to use my warranty for the fault in my device (Acer Phils. Inc., Paco, Manila). I told them my problem, and they took my laptop for a week. I already received my laptop recently; the actions taken were thermal repasting and 2 day burn-in with delta force (game I experienced the blackout).
After receiving and testing, I still experience the blackouts while gaming (Arena Breakout this time) around 45 minutes. This led me to a lot of testing with Furmark and Cinebench 2024 to test my GPU/CPU. My CPU deemed to be stable and working fine. On the other hand, my GPU does a great job handling 4K/UHD graphics; however, it occasionally drops in performance.
Here's my observation of the GPU:
1. FPS crash occurs (141 to 7 FPS dip)
2. 70W to less than 10W dip in power
3. 60°C to 40°C dip in temperature
4. 1.8GHz to 0.2GHz dip in clock speed
I noticed that there's a drop in power consumption combined with the drop in FPS, clock speed, and temperature. My conjecture is that thermal throttling is not the problem, while power cut happens occasionally.
If so, does that mean the power happens to be less than what it consumes? This lead me to try an AC Adapter with higher wattage (180W) with same 19.5V, still being an acer brand. Does this help my case? I want to confirm before doing it.
