ASUS power jack


These power adapters are almost impossible to buy, or rather obtaining a cheap adapter with the correct connector is very very difficult to find. The original adapters cost 800-1200 baht.

Anyway, I thought that instead of buying an expensive new, or second hand, supply (the 240 W or 330W can go for up to £100+), is it possible to to fix them? Is there a common failure mode? A recurring point of failure?

Unfortunately, it overheats and then shuts down, or rather, goes to sleep, shortly after being powered on.   This self imposed sleep happens quickly, especially if the processor is being pushed, such as by running a full screen video in VLC.
