Hi All, I am working on a Lenovo Thinkpad T490 liquid spill. The spill/corrosion broken some tracks & cannot figure out without the Boardview. Can anyone share the boardview for this Lenovo ThinkPad T490 NM-B901 Rev: 1 . I think ThinkPad T590 are the same. Thanks in advance -
I have a Lenovo ThinkPad T490 that will not start. When the charger is plugged in, the power indicator flashes 3 times, the charging LED lights up, the fan starts spinning, but the charger remains at 5V, which is not the fault of the charger.
The 5V appear on the main power rail at the current sensing resistor.
What can I check next? How can I check the power delivery protocol?

Hi,
For some time I fight with a Lenovo x390, FT491/FX390 NM-B891 Rev:2.0

Hello there.
I am working on a Lenovo Legion T5-26AMR5 desktop that currently has a corrupt BIOS and I have been unsuccessful thus far in trying to fix it myself.
History:
1. This computer came to me initially with an error message that said "BiInitializeLibrary failed 0xc0000001" or "0135 fan error". It would always be one of the two errors. It should be noted that when it produced the fan error, there was no physical problem with the fans. They were all spinning just fine.
I searched for this error online and discovered...
