Thanks for the tips, Scruge!

I'm beginning to think we need a sub-forum for computer problems! sf-laugh

Sony had a good computer in the VIAO, but they too have pulled out of the market in Canada.

…It is periodically overheating again now. I don't know anything about its innards, but I can feel it underneath and also along the top of the keyboard near the hinge. Eventually, if it runs true to form, the power cord at the computer end will become quite hot as well and will jump out of its socket.

The technicians may not be able to fix it permanently, but they do seem to be able to fix it temporarily, which I find strange. Within a few weeks it is back to its old tricks.

I've had similar problems, ultimately, with all my laptops, but the other ones had run a reasonable course of 3 to 5 years first. One of them was repaired and that repair lasted another year or so - it just required a new connector where the power cord goes in, and they stopped making those available - nothing else was wrong with it (Sony VIAO). But not so with this current ASUS.

Those are significant observations about the power connector. Some of the chips may get hot, like the CPU. But, that power connector should not get that hot. Those are signs of excessive current.

The extra heat from that excessive current could be melting solder joints. That would explain how the technicians are able to fix the problem temporarily. They replace and resolder the power connector and resolder any other loose joints they find. It will last until the heat melts the solder joints again.

Do your laptops have a significant number of accessories or peripherals plugged into the USB ports directly or through an unpowered USB hub?

Such peripherals will draw power through the USB ports. The extra power will be supplied through the laptop's power system via that power connector.

Do you ever use the laptop on battery power alone ? If not then maybe you should try it and see if you still experience these overheating issues and also see how long it lasts on battery power alone. It may have something to do with the charger/adapter and this might help isolate your problem. Battery might be overcharging.

I don't use any peripherals.

I do have the screen set for highest brightness as I need this for my vision problems This means the battery drains faster, from what i can tell. If I unplug it, it only lasts about an hour or so, which is a nuisance, so I stopped doing that. Also, it would always be dead if I unplugged it and left it alone with the cover closed.
However, they did put in a new battery the last time, so perhaps I should try this approach again.
