Zenbook 13 UX363 power issues

[DanTheMan]

Hi all. A while back my Zenbook crashed a few times and had trouble finding a boot device on restart. Leaving it to rest for a few minutes seemed to fix the problem. Today when I was using it on battery I plugged in the power cable and bang... everything went sluggish, I could switch apps and eventually the mouse froze and it rebooted. And couldn't find a boot device.

So I think there is something seriously wrong with the power or thermals on this laptop. I did some digging and this is a Kernel Power 41 error and the logs seem to coincide with every time I remember this happening. I'd say it's been on average once a month Starting 10 months ago with this two year old laptop.

Does this laptop model suffer from overheating? I like to use it lid closed with a USB hub monitor, which of course blocks both underside (no screen lifting of base) and keyboard heat dissipation. Could this be it? I'm using it open now with external screen only mode and the fan is quiet and the laptop is warm but not hot.

Any suggestions welcome!

Using the laptop with the screen closed can indeed affect its cooling, so we do not recommend using it this way.
If your laptop still has thermal issues, we suggest taking it to a service center for further inspection.

OK, it's good to know this is a known issue at least. It's a pity I can't use the neatest option then of just plugging in the USB C and using the external keyboard and mouse connect to the hub screen, but more important that I don't melt the laptop!

If I can report back more than a month later, this problem seems to have disappeared. Unfortunately the Zenbook needs the screen open for cooling, so it won't be as neat as a Macbook Air or something when docked. Anyway, I've it set to second screen only any I get my face unlock back so not too bad.

OK, and another month later I needed 4 reboots to get past the "No bootable device" BIOS screen. Time to look for another laptop I think. Don't know would I go for Asus again if this is a regular thing. If it's easy enough to do I'll try reseating the SSD.
