Apple Macbook Pro A2338 EMC8162 lid sensor doesn't work
I have an Macbook Pro A2338 after small liquid damage, all working fine but keyboard was sticky so I have replaced palmrest for genuine second hand and now lid sensor doesn't recognize when I'm closing the lid. Display is always on, can't find sensor for that model, can someone explain my how does it work, where that flex is if there is any.
Maybe that the motherboard issue, not sure where to start.
Thank You -

Asus FA507R no power, capacitor needed
Hello
I've got an Asus laptop which received with no power, so I found that one capacitor been damaged. I don't have schematics for that board which is DANJMMB11A0 REV:A
Without that caps laptop is turning on fine so problem more likely is sorted but I would like to put back the correct one as it should be.
If any way could help with sorting out specification somehow, I just know that my meter shows 11,2uF but is it 50V or 10V ?? or any others.
See attached photo off the capacitor, maybe someone have same motherboard and can check it for me please.

Hello
Can I have help with unlocking my bios please, when I'm using RCunlocker, laptop doesn't turn on at all, can't get into recovery. Laptop model is Lenovo 100E Chromebook 2nd gen BM5866 V1.4.
Is it possible that the laptop will not work with any other BIOS just with original?
Another strange thing is that I've power wash it and laptop doesn't have chromeOS anymore now and even I can't install new by using recovery....
