JUMP CI HDMI ONE S...

Hi

Yesterday while browsing the internet with my laptop I noticed that 3 keyboard buttons were not working anymore.

Today, the notebook doesn't boot anymore. My assumption is that the keyboard went bad because the power button is on the keyboard.

Is there a way to jump start directly from the motherboard?

I tried to short all the pins of the connector for the keyboard cable with no luck.

I found the schematics here on badcaps, but I didn't find the pin out for the keyboard. But truth be told, I am just a hobbyist who tries...

Hey guys, long story short, I need the schematic for my “HP Envy x360 13-ay0175ng” motherboard to see what pins I need to short to start it up without a keyboard attached.

I just got this TV in today, and originally it would flash the logo and have no backlight afterwards. I could see the image without the backlight with a flashlight.

Having no 9V batteries or anything on hand, and all the backlight LEDs looking fine during the flash, I decided to jump BL_ON and DIM on the power board/mainboard (White and purple wire) with them still plugged in using some scissors to connect my shielded voltmeter cables.

After jumping a few times, the backlight stayed on. Why?

I didn't measure any voltages beforehand... So just wondering...

just had a brainwave .
i have here a good set of 18650 cells from a 36v pack . and am wondering how easy and if it will work to be arranged for a 12v jump pack for cars etc . .
just wondering about charging it .. i know it will need the correct bms . its the charger bit i am stuck on .. will a linear charger work ?
