Board ID: DA0BLBMB6F0 REV. F0
Schematic: https://www.badcaps.net/forum/showth...satellite+l755
BIOS (Flashed): https://www.badcaps.net/forum/showthread.php?t=31424
first problem was PQ21 shorted on all legs (Gate, Drain & Source Connected) and it's a NIKOS P1203ED not AOD403 like on schematic, after replacing it and make sure all legs not connected each other everything normal. but anomalies occured when i inserted 90% charged battery to the system and plugged the bench power supply, the amperage jump to the max (5A) like shorted and the PQ21 was hot. after realizing that PQ21 is hot i check the legs of it and it still normal, but sometime (once in 10 time attempt) it can charged the 90% charged battery without consuming maximum capabilities of my bench PSU.
things done/replaced (after PQ21 replaced):
- PD2, PD4, PD9
- PQ1, PQ17
- PU1
- EC & Main bios flash
anyone had other idea where to look again?
