Re: HP HSTNN-HA09 laptop power brick - power led turns off
I've checked the voltage at the rectifier, I get 105V, 105V and 323V. I read 323/322V at the large capacitor. I each case, these readings stay constant even when the PSU has stopped.
The readings at the two small lytics caps are always random between 15 and 20V, whether it's been just plugged or the PS has shut down.
