I am an electronics enthusiast. I came to this forum looking for a BIOS file and found a lot of useful information. I hope to contribute some knowledge here in the future as well.
Hi techies !
I'm a french 45 yo fan of at least trying to repair almost everything I can touch, from cars, mower, computers, smartphones, etc. and also playing with 3D printer a bit.
It's like a smart hobby to extend the lifetime of the equipments I have between my hands, coming from my family, my friends, neighbors... I hate to throw in garbage any of possible working things.
So I'm not a deep electronician, I know some basic principles I've learned from school a while ago, but nut I'm also asking my son to bring me some hands, what he's doing with fun, sharing fun together.
I like spending my free time reading and seeing tutorials too, always trying to learn new stuffs.
So all the best to everyone and happy to joint he community !

flashed the bios clean me and updated from the Lenovo site, then removed the switch and immediately jumped the S3 from pins 1 to 4, 2 to 3 but the problem remained the same, thank you
please help friends, I have 3 T490 units with the same case, the USB type C is completely dead, showing 20v 0 amp, loss of voltage VINT20_IN resistance to ground is fine, thank you
I think the problem is that I lost the voltage at PQ0008 pon 1 -PWRSHUTDOWN which should have been high which was picked up by R9512 VCC3SW, thank you very much for your help

usb meter 20v 0.00 amp, after I took the VSYS measurement the drop was only `9.2v which should have been 10.2v I measured from a normal matherboard machine, the VSYS path resistance to ground diode mode is 1900 thank you
