    Hello.

    We have Elitebook 8470P 6050A2466401-MB-A04 . After several BIOS flash, it do this: Light on charging OK , but laptop wont turn on (AT ALL , power led is not emitting). All components around BIOS ok (soldered by IR.) checked for short, all looks OK.

    We got 8 different BIOS flash for the same motherboard : 6050A2466401-MB-A04.

    laptop wont turn on. By shcematic A04 there are missing some parts (Q2993). Motherboard 6050A2466401-MB-A04 need schematic 6050A2466401-MB-A02 (Calvin UMA MV BUILD 2012.03.08) to solve propertly. (guess some manufacturer mistake in label of the motherboards)

    UPDATE:
    None of motherboard works, all circuits looks OK, changed BQ 736 and TPS , no result, voltage inputs and outputs in both circuits OK , error on transistors around BQ 736, (Q6012) input OK output not working, transistor OK

    can anyone help ? looks like lot of those laptops doing the same error. e got now 3 motherboards with same error .
