Sometimes it turns on, sometimes it doesn't. Blue LED lights up, does not respond to any command, does not turn on back light. | Check voltages on ic 1000. 3.3v line. Normal case, when connecting pin 7 IC 1002 tsound must be 3.3v. If you don't have this voltage, check the 3.3v line r1009 (0Ω). this said which was changed to 300Ω. | Check, replace r 1009 | arock |

The video comes out through the vga port but does not appear on the notebook's integrated screen | The 3.3vlcd did not appear in the lcd connector. q2 and q4 (they are under the wireless network card) generate 3.3v and were soldered cold. the region of q42 and q44 (back of the motherboard) with a lot of oxidation. q42 and q44 switch 3.3v to the integrated display. | Resolder q2 and q4. I also resoldered q42 and q44, but for these two I needed to redo some tracks because oxidation destroyed some connections (ground on q44 and the q44-q42 connection) I used thin enamelled transformer wire. | 2000 |
