After seeing Big Clive's adapter fail teardown, where it shorted mains HV DC bus to output(-) due to the hazardous live heatsink shorting to the output inductor, very scary, fuse was bypassed. No hi-pot test, fake safety approvals.
OP a 0.33uF film cap is X-cap and should not kill the laptop. Wonder what this cap is that failed short. Y-cap is typ. 2,200pF ceramic.
Why do people pay and power expensive stuff worth $1,000's dollars from cheap chinese unsafe power supplies?
