A2337 - L7800 burned

[samstown]

Hi,

Macbook air suden death. It was stuck at 5v -0,4 amp. I found L7800 completely burned. I removed it, now it's 5V -0,004 amp.

Now I have diode mode .464 PIN1 and .224 PIN2 where L7800 was.

Can I replace it and try to power or should I check something else ?

Thanks
Claude

Replace it and test.
If gets hot, replace U7700.
