I found a netbook motherboard that was working with broken LCD, it was same model KBC, as soon as I plug the power cable, the WLAN light (D537) is on and fan is running nonstop, I can't power it off unless I unplug cable and I have 3.3V in BIOS pins 1,3,7,8.
hi every one, I got before a problem with my laptop, black screen.
In this case the graphic chip (ATI) after some year of working and the hi temperature ; some pins of the BGA soldering slough from the board , because the manufacturer in this period used a bad tin, the same thing happen with the xbox(it use the ATI graphic card).
to resolve this problem; you can make your a graphic card work again by using hot air station to heat the chip until the tin attach again, or use the big means and desolder a chip and remove the old tin and replace with new one (use specific material).
