Dell Inspiron N4010 (DA0UM8MB6E0 Rev:E) - Water Damage

[orientalsniper]

Hello all, I received this laptop with water damage.

Schematic (I think this is the right one):


Symptoms:
a) Battery LED lights up for 3-5 seconds then goes out.
b) Power LED used to flicker around same timeframe.
c) C605 and C607 was missing and each had a pad with solder missing.
d) Seems like only top layer of motherboard was affected.

Attempts post-diagnostics:
a) Soldered the 2 missing capacitors.
b) C605 didn't have any readings, C607 measured 19V
c) Cleaned out board with IP-Alcohol.
