But today, I’m making an exception here. Why? No idea. Perhaps only because the repair details are still “fresh” in my head… which is ironic, given this is a 16 year old monitor that hardly anyone will care about today. It is new to me, though.

by alro7779Hello, there!
The problem with this laptop is that it does not show video at all, even if I connect an external HDMI screen device to its port.
I got it disassembled, and first of all it does have its VDC in (19.81). I checked the 5 inductors having the charger plugged in, and the voltage readings are:

1: 9.04 VDC
2: 1.203 VDC
3: 0.813 VDC
4: 3.403 VDC
5: 5.133 VDC

by momakaI know I've been a little scarce lately (like the last 2-3 years), but I'm still here and still doing my thing with fixing PSUs.
For today's considerations, I have a Seasonic B12 BC-550 [A551bcafh] 550 Watt ATX power supply for you (click on links for full size images).

It's a modern ATX unit with fixed (non-modular) cables and an 80-plus bronze certificate. Here's the label:
