I have an HP Mini Note 2133 that will not power on. When I plug in the AC adapter the light right next to the DC jack will light up blue/white then turn off after 1 second if there is no battery installed. If the battery is installed, the battery charge/orange light with light and stay on. Update (10/01/2022) that didn’t worked. Btw the laptop started ding this after a reflow
@George kts If you had mentioned in your question at first, that the board had been “reflowed” I wouldn’t have posted the answer that I did. Reflowing boards can cause problems if you get it wrong e.g. components losing connection with the board, components connections going short circuit because solder has flowed between them etc You will need to get hold of the schematics for the motherboard (what is the make and model number of the board - not the HP part number - printed on the board) and then use them to trace the power rails to see what’s happening.
