Follow up from this thread.
I bought my laptop on December 2020. I noticed some blue (WHEA_UNCORRECTABLE_ERROR) screens 1-5x a day in about May-ish but didn't bother too much as I though it would go away. Suddenly, the power cable was not charging the laptop, and I was forced to get warranty to solve this issue. The issue was a faulty motherboard. The issue was fixed.
I got this fixed on August 2021. A few months later, the exact same issue persisted and the mechanic changed the motherboard a few days ago.
Now, a few days later, I'm experiencing new issues where the laptop will not boot but be "preparing automatic repair", then turn off, then start again. This will be an endless cycle. The laptop will randomly reboot at any given moment, which makes it impossible for work tasks or study.
I'm reaching 12 months warranty, and I'm worried these issues will persist beyond warranty, which adds another layer of difficulty, even though ACCC should be on my side considering the history of faults.
What are my options here? I'm going to add a poll. Let me know what you think.
EDIT: now the laptop boots up, but its just a 100% black screen. Nothing else. No options or buttons to press. I'm going to call and harass Lenovo every day for a replacement it seems.
