L7100 : 1 volt and 0 repeats
L7330 : 5volt and 0

PM_SLP_S3_L : 3 volt and 0
PP5V_S3_P5VS0FET : 5 volt and 0
PP5V_S3_REG : 5 volt and 0

PP3V3_S5_REG :3.3 Volt fixed (L7220)
PPVIN_S5_5VS3 : 12.13 volt fixed
PP3V3_S0_P3V3S0FET : 3.3 volt fixed
PP5V_S5_P5VSUSFET : 5 volt fixed
PP5V_SUS_FET : 5 volt fixed


Should I inject 5 volts into the L7260 from outside?

Diod mode
PM_SLP_S3_L : 560
L7100 : 27
L7260 : 150 (PP5V_S3_P5VS0FET)

"L7330 : 5volt and 0"
5V is a really bad value there; did you check at C7340?

What about L7630, L7760/70 and other power rails?

sorry i spelled it wrong L7260 giving 5 volts.

L7330 and (C7340) comes 1.5 volts then 0 volts
L7630 1 volts then 0 volt
L7760 1.8 volts then 0 vols
L7770 1.5 volt then 0 volts

I noticed that the bios IC is heated. I tried to write new bios but I couldn't. I inserted another integrated and the device turned on. but it stays at 0.89 amps
