E480 (without RX 550) fan/heat issues?

Hello everybody,

 

I have already read certain posts about the fan/heat issue the E480 seems to be having in the model with the RX 550.

As it is difficult to differentiate which posts are belonging to the model with the radeon graphics card and which posts are belonging to the model without the graphics card I would like to open this new tread.

This therefore only serves the purpose to analyze the fan behaviour of the E480 without the graphics card.

 

I am thinking about buying the model without the RX550, but I am afraid that the fan might go crazy at random times. 

 

What are your experiences with the fan?

As I want to install both Windows and Linux, It would be great if you could differentiate this as well.

 

Best Regards,

TillChima

Does anyone know if a P52 is ordered w/o any SSD if it comes with the adapter or not? If not, does it use the same as the P51, 4XB0K59917 I believe is the part#.

Fingerprint setup will not open Windows 10 X1 Carbon Gen5

In the settings menu under Sign In Options, when I select Fingerprint Set Up it at first appears that the command is working, but the setup window never opens. I see a waiting wheel for a few seconds and then the execution fails. Can anyone help me to diagnose this? 

 

I had a fingerprint set up and it was working fine. I noticed the issue when I went to add a second. Some diagnosis forums suggested clearing saved fingerprints and starting over, but this didnt work and now I cant use the fingerprint reader at all…

Unplugging USB Power cable triggers "Power Surge on the USB Port" warning

I’m having a bizarre issue where simply unplugging the official Lenovo power supply from the orange USB power port causes the laptop to immediately issue the subject warning, along with the detail "A USB device has malfunctioned and exceeded the power limits of its hub port".   This warning pops up every 5 seconds, unless clicked on, where reset/close options do nothing. 

 

Crazy thing is, NOTHING is plugged into any USB port!   Reattaching the power supply does not clear the error.  Only rebooting with the power supply cable connected clears the error.   Remove the power cable, and the error instantly comes back.   All of the USB ports actually work fine, including the USB C port, whether or not this message is active.

 

Maybe it is a hardware issue, but ALL the USB ports actually work fine.  I can’t figure how unpluging the power source can trigger a USB power surge when nothing is actually connected and the battery is fully charged.  I’ve removed/reinstalled the USB Root hub, eXtensible Host Controller, Generic USB Hub, etc., drivers multiple times to no avail.   No errors with any devices are apparent in the device manager.

 

I’ve seen a lot of issues reported about USB power surges but none like mine.   Anyone have any ideas about this?
