Good morning forum. This laptop enters me completely dead, does not turn on. Disassembling the board I did not find traces of oxide, I tried to reprogram the bios but nothing to do, by measuring the voltages on the power on button I find the 3.3 v which drops to 0v when I press it. Couldn't find schematic or boardview
*** update***
Sorry for the post, I found the damage, oxide under a sticker. The resistor was broken connected to pin 3 (enabler1) of L3533. Not knowing the resistance value, I measured the one connected to pin 5 (enabler2) and it is 0 ohm. I then made a bridge and the notebook works fine.
