Where is lcd lid close switch

I would say either screen inverter board bad inverter feeds backlight tube or backlight tube bad. So, good to know what that little part is called. I'm going to replace that and see if it was it.

What about the magnetic counterpart of it? Could that also be the origin of the malfunction? Hm, getting a new screen would give me a new screen inverter board too. Gonna check availabilities and prices Edit: looks like a screen only comes with display and cables, no inverter board. I've ordered such a board. And now guess what, the screen is back on. Maybe fondling around under the cover pushed something in the right corner.

The screen is flickering sometimes though. There are sometimes pixel thin horizontal lines that flash up and divide the screen into four segments. Sometimes there are more shorter lines. Is that a symptom of a malfunctioning inverter board or the backlight tubes?

Actually before opening up the laptop, I would need to purchase a replacement part for it. Can you share a picture of how it looks like so I can purchase it from the local market or share any online link. Yes, although I haven't opened up my laptop to take a look at the switch foe reference. I guess I'll have to check in the local stores if I can find this part for my laptop.

Move the lid to the close position, wherever the magnet position of the LCD cover meets the bottom case, is where the sensor should be located.

It is entirely possible that you dislodged the magnet when you replaced the LCD. On some of the older models it was about an inch from the right hinge. Hope this helps, good luck. So, theoretically, with the bezel removed, there should be no "lid switch" action and the power button should work.

Sounds like I need to tear it down to the power button. Not necessarily. If your lid switch is not functioning it may be stuck in the off position. Run a magnet along the outer edges of your laptop and see if that activates the switch. When you replaced you LCD, did you make sure that all your parts went back in the proper place? Any leftover's? No leftovers.
