Hello
I try to help a friend with his broken laptop and I am hoping that some one here resonises the symtoons so maybe I can fix it. I already searched the forum and read many as I could, got also the schematics, so thanks for that.
Laptop turns on and the screen/backlight does on off repeatedly
With ram in other socket same, but slower frequently
With double ram even slower
a 4gb module blicks faster then a 8gb
with no ram there is no screen blinking
all is the same, with battery or ac adapter.
battery is charging
cpu turns on after a while.
Around PQ40 I measure some capacitor on 139 ohm, is that shorted ?
Best regards
Jeroen
This guy has the same but has a open end of hidden part 3.
