After two years, my dead gaming laptop came back to life

I have an MSI GE72 2QD Apache that stopped working completely it would not turn on, with or without the battery. I took it to a well-known repair shop, and they diagnosed the problem as a dead motherboard, which would’ve been pretty expensive to replace. Instead of fixing it, I decided to buy a new laptop.

Today, as I was about to throw the old one away, I figured I’d plug it in one last time and to my surprise, it powered on! :sob:

Now, I am wondering if I can rely on it going forward, and what might’ve caused this in the first place. I’m also considering fixing the dead pixels on the screen, but since a 17-inch replacement is costly, I am unsure if it’s worth it. I am also afraid the same issue could happen again. Any thoughts?

(I originally bought the laptop in 2017.)

Before spending any money on repairs, you might want to wait a few days to see if the laptop dies once more. These problems may occasionally be transient, but if they persist, it might be worthwhile to remedy.

Observed, I appreciate your feedback.

And play some games to see if it functions or not! If it does, you’re safe; it appears that the devil roused it.

If you are thinking of upgrading or getting rid of it, I would honestly suggest giving it to your neighborhood recycler. It’s not a good idea to leave something in a landfill, especially because it will likely take the entire thing 1000+ years to melt away unless it was melted at extremely high temperatures.

Just keep the RAM, storage, and display intact. Even the motherboard, in fact. And if that laptop was well-liked enough to warrant fixing another, the repairman might buy it. Additionally, you can use the laptop’s external display as a secondary display.

I am not sure why this occurs, but my theory is that as time went on and there was no longer any electricity flowing through the circuits, a chemical reaction was set off, allowing the computer to function once more. I’ve experienced it previously, but I can’t explain it satisfactorily. Perhaps a capacitor that has been charged with the wrong polarity? To ensure the laptops are in good working order, I would put them through a stress test and check if they continue functioning.

The system, especially the Cmos battery, was probably drained.

Okay, so can a laptop not boot up because of the CMOS?
