Noise and high temperature when charging with 140W

Heyho,

yesterday I had a weird behaviour with my FW16 when charging. But maybe it is not weird and I was just too nervous.
The battery was at 36% when I connected it to the charger. It then started to make some constant “brizzling” noise, coming from the top left quarter of the laptop I would say. Not super loud, but notable. The cable was plugged in at the top right USB-C extension card.
It also got very hot at the area located near the Y key on the bottom side. The area below the trackpad, where the battery is, did not heat up that much. Also the fans started to spin after 5-10 seconds (the laptop was turned on, but I didn’t do anything).

I unplugged the charger as I was not sure if something is odd.
Currently it is connected, but as the laptop is near maximum capacity I guess it does not try to drag that much load.

The charger supports up to 140 Watts. It is from Intenso

Can somebody confirm this is expected?

I cannot confirm that it is expected, but mine started to noticeable buzz too when charging with over 40 watts (original charger and cable)
I did not notice any excessive heat but I am also using an external mouse and keyboard so I don’t come in contact for the most part

At least that there is some noise is a very helpful insight for me :slight_smile:
Could you locate from where it comes from? For me it was confusing that it seems to come from the upper/mid left part. If any I would have expected it near the battery or the extension card.
I did a Bios update to the latest version. With that, at least the fans do not start to spin and it also seems to be less heat. So the noise mainly is what remains as “strange” issue.

I’ve ordered another RAM stick, when that gets here I’ll let it run open and see if I can locate the noise and maybe a temperature hotspot too

Thank you very much!

I let mine run without the midplate today, but could only locate the sound to somewhere around the interposer and CPU, also took a picture but nothing unusual as far as I’m concerned (the laptop was pulling 100W for about 15 Minutes at this point)

Thank you for the investigation :slight_smile:
I’ll check if that is the same location, but good to know already it is not coming from the battery for you too!
