please help friends thinkpad T470 board CT470 series NM-A931 error post "bottom cover tamper detection error"
I've already
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
Please help friends, thinkpad t480 nm-b501 is dead, help me fix it, thank you
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
