Backlight is unreliable, behaves intermittently
Hello! I have a laptop, serial F8V, that has an intermittent backlight -- sometimes it's not on when the laptop powers on, and sometimes it is. Sometimes the backlight doesn't come back when the laptop awakens from sleep. You can always generally get it back on, but it takes powering on/off, etc.
The board previously had some corrosion that was cleaned off, and previously was not powering on fully, and just showing a glowing sleep light. So that issue seems to be resolved, but now I've got this backlight problem.
The question is this: Would this problem more typically be the board itself, the topcase/keyboar
Is this a good question?
