Re: Inspiron 15 Gaming 7577 la-e992p

Does anyone know the part number for the keyboard connector on the motherboard?

I'm currently working on a 2017 EVGA SC17 Laptop that will not post and I'm unable to find anyone working on these or any boardviews or schematics, hopefully someone here has them?

Thank you so much!

Geez, the prior work and liquid damage is making me forget the basics, SMC_LID is 0V.

Re: 820-3787 No LCD_BKLT_EN



Thanks Piernov, I appreciate your response. I thought I was testing with a known good screen but I had grabbed the wrong one (I need to read my labels on the back first), sorry about that. So here is the update, blinking folder due to missing SSD but still no backlight and LCD_BKLT_EN is still near 0V. Fuse voltage is 12.5V (but recall prior work on the board replaced it with a wire). So the backlight chip is not being told to turn on by U9600. Everything else seems fine, could it be that this new short in the screen burned out U9600?...

This is quite a head-scratcher for me, just received a board yesterday from a customer and it has a shorted LCD cable and connector on the LCD assembly. Backlight circuit resistance without the screen is the nominal >150kOhm. Using a good test screen I still have no image and no backlight.

This is where it gets weird...

Prior work on been done on this board, appears that there was liquid around backlight circuit area in the past and the fuse F7700 was replaced with a wire.

LCD_PWR_EN is good 5V but LCD_BKLT_EN is near 0V. Resistance on LCD_BKLT_EN...
