UPDATE:
I did compare the original bios that I uploaded to 084B9.rar and both are exactly the same. I extracted the original bios from hp drivers support and compared and the DMI and BID information is the same that Hoaca388 uploaded and original upload provided in post 1. Am i missing something here? please correct me if i am wrong.

tried flashing 084b9.rar and same result. 5 long 4 short.
tired flashing 084c0.rar and receiving "Buffer size not equal to IC size"
does this unit have 2 bios IC? I removed the board and checked the other side, seems it only has one?Last edited by ub6ib969; 04-18-2024, 11:43 AM.

Hi hoaca388,
Do I use both .rar files attached ? Do I have to enter the DMI information?

Lenovo Flex 5 14ARE05 LC55-14A U7204 help?
Lenovo Flex 5 14ARE06 unit does not power on. When usb-c is attached U7204 (TPS66021YBGR-GP) gets very hot. I replaced it and still gets very hot. Unit is getting 20V and 0.228amps. when checking around I noticed that PC1051 & PC1052 are shorted (1V_VDDCR_SOC) does this mean that the APU1 is shorted ? or am i missing something? any help would be great....
