Hi all,
Got this HP AC adapter model HSTNN-CA15(output 19.5V, 3.33A) for HP laptop which suddenly died yesterday.
Opened the adapter casing and did not find any burning part, loose or broken wire but the square T3.15A fuse still has continuity.
I pulled out the biggest green resistor nearest to main cap at CX2. The resistor has 5 band which is red,red,gray,gold,white. Is this a 22.8 ohm 0.5w type resistor(lenght abt 1 cm)? Please correct me if i m wrong. It measured about 0.4 ohm on dmm, so it is bad. I have no exact replacement so i use a 30 ohm 2w from my stock but the adapter still has no output.
Appreciate anyone with experience to kindly guide and assist on how to revive this dead adapter and not adding to the dumpster instead.
