Hi everyone,
I am desperately after a schematic for this board.
The unit cam from another repair store with no power issue, no lights, nothing.
I assume someone tried to power it with 19v (its a 15v unit) as a smd fuse was blown, after replacing it the DC power light is on, however no battery charge or response from power button.
Manually shorting the 3v 4th pin (on pwr flex conn) to ground gets the unit to throw an error sequence on the dc_in led (10100010) which i translated to A2 (am I wrong?) which in the service manual is ;
A2h 1R05-E1V voltage is under 0.89V when the computer is booting up.
I have no idea where to go from there, can anyone help?
Aside from this the charging ic is a FUJITSU MB39A118B (http://www.alldatasheet.com/datashee...39A119_08.html)
I think its no good, I get..
1 - 15v
2 - 15v
3 - 15v
4 - 2v
5 - 2v
6 - 0v
7 - 0v
8 - 1.6v
19 - 0v
27 - 1.2v
Im going to change it but I thought id ask first in case im doing something wrong.
