Hi, have a la-b991p that power up but has no video, no usb mouse or pendrive light, or acces.
Seems a problem like in this thread:
https://www.badcaps.net/forum/showthread.php?t=72709
All voltages are present and main bios/ ec-bios are programmed with good dumps,
PLT RST goes low and then high, so seems that power up sequence are fulfilled also.
The weird thing is that there are no activity on spi bus.
Bios chip also replaced.
Any comments about this problem?
