The SONY PCG-61A11W laptop had a 19V .after checking that the C4906 was burning, i changed it. 19 v circuit is clear. but i did not have 3 and 5 volt. after checking i replaced PU4103 (RT8223M) and laptop turn on. laptop worket 3-4 hour without problem but suddenly turn off !! i missed 3 and 5 v . now i connect charger 3 and 5 v present but next 1 or 2 Second will be disconnect.
now i replaceD new IC RT8223M and motherboard go turn on but next 2 3 hour go offfff.
The main problem with the device is that the circuit 3. It's not 5 volts while I'm sure of the safety of IC. Sometimes, the voltage is 3.5, but it is cut short soon.
Accept my apology for bad speak english . (I'm learning)
