M90 (la-2881p) charging

ayad

hi all , when i push bottom switch , i got this warning in brief :
you should use ac adapter 130W , hit F1 to shut down
i have used adapter with 130 w but nothing change
i have tested PR2 PQ2 PD1 PU12 PU11 ext.... all are ok
so could i change bios dump to prevent that message ?

Try a BIOS for Dell Inspiron 9400 - the same MB, but it work with 90W power supply und hasn`t this "press F1";

Look oscilloscope on a thin wire should go charging data. Look pulses in the laptop can be a problem in the connector. This is a typical problem.
