Hi. I have problem with dell laptop E6440 val91 la-9934p rev.1.
I turn on the laptop and it turns off instantly. After 5-6 attempts it turns on normally. I saw that it was burnt PU800, CD3301B Power Controller Chip.
If you see in the photo someone tried to do bypass and remove PR831, PR832, PC820, PR838.
I will replace CD3301B. I have the schematic but i dont know what are the characteristics of other componets to replace...
