Hey guys, grateful if anyone can provide known good Main BIOS + EC for Toshiba Satellite L40-A.
Motherboard: LA-9865P rev 1A
EC: KB9012QF
Please find attached original main BIOS dump and another bios downloaded from (https://www.badcaps.net/forum/showth...ht=toshiba+L40). I will attach EC dump as soon as I dump it.
Laptop issue:
Laptop came in as no power. After initial diagnostics, a shorted input mosfet was found and replaced. Laptops then exhibits issue hereunder.
when power button is pressed, board turns on (fan spins, hdd spins, etc but no display) and turns off after about 3-5seconds.
No other shorts were found and all voltage rails seems to be present and stable when power button is pressed as well as stable 3.3V when off.
upon first connection of charger, laptop idle draw is 21mA @19.7V. After first boot cycle (Off-On-Off), current draw drops to 8mA @19.7V.
Laptop consumes 320mA at start-up and stabilize quickly to 261mA@19.7V.
Laptop charges fine and exhibit same issue with AC only, Battery only & both AC + Battery. Any help is greatly appreciated.
