I’ve experience issues with my Acer X1700 only after two years of used.
The problem was: random kernel panic, while memtest86 ran successfully.
I then open the case, found out capacitors (close to ram) where bulgy.
Measuring the voltage, shown lot of noise around 2V.
I then salvaged from an old mobo 2 capacitor (remember, at least same voltage and capacity).
And solder the new one, and check the tension: everything is fine now and then.
Seems to be a plague, such a problem, it’s mainly translated in ….
One word only: ChinaWonderland……
