NEED 8MB FILE FOR 6050A2466401-MB-A04
HP 6470b 6050A2466401 8MB
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)
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 .
